PART B Passage I:

The population of the world has been increasing faster and faster. In 10,000 B.C., there were probably 10 million people. In A.D. 1, there were 300 million. It took 1750 years for the population to reach 625 million, a little more than double the A.D. 1 figure. In 1990, there were 5.3 billion people. By the year 2000, the world's population was over 6 billion, and by 2050, it is expected to reach 10 billion. Does the earth have enough natural resources to support this many people? Different scientists give different answers to this question. Some say that there are enough resources to support more than 6 billion people. However, the richest countries, with a small percentage of the world's population, use most of the resources. If these resources could be distributed more equally around the world, there would be enough for everyone. Other scientists say that we must limit population growth because our resources are limited. Only 10 percent of the earth's land can be used for farming and another 20 percent for raising animals. It is possible to increase the amount of farmland, but only a little. Some land in developing countries could be more productive if people started using modern farming methods, but this would not increase worldwide production by much, We all know that there is a limited amount of petroleum. There are also limits to the amounts of metals. There is a limit to the amount of water we can use since most of the earth's water is salt water, and most of

欧阳总创编 2021..02.13

欧阳总创编 2021..02.13

the fresh water is frozen at the North and South Poles. It is difficult to say how many people the earth can support, but it will help everyone if we can limit population growth before serious shortages develop. The problem is how to do it. 1. Between 1990 and 2000, what changes did the world population have? It had increased by almost a billion

2. According to some scientists, which of the following is true? The world’s resources are adequate but not evently distributed 3. Why can't most of the earth's water be used?

It is mostly salt or frozen at the North and South Poles

4. In developing countries, what does the use of medern farming methods result in? 5. According to the author, what can you infer from the passage? II 1.There were probably 10 million people. 2.It is expected to be 10 billion.

3.If the resources could be distributed more equally around the world, there would be enoueh for everyone. 4.Only 10 percent.

5. It is how to limit population growth.

Passage II:

Fresh water, life itself, has never come easy in the Middle East. Ever since the Old Testament when God punished man with 40 days and 40 nights of rain, water supplies here have been dwindling. The rainfall only comes in winter and drains quickly through the semiarid land, leaving the soil to bake and to thirst for next November. The region's accelerating population growth, expanding agriculture, industrialization, and higher living standards demand more fresh water. Drought and pollution limit its availability. War and mismanagement squander it. Nations like Israel and Jordan are swiftly sliding into that zone where they are using all the water resources available to them. They have only 15 to 20 years left before their agriculture, and ultimately their food security, is threatened. Even amid the scarcity there are haves and have-nots. Compared with the United States, which has a freshwater potential of 10,000 cubic meters a year for each citizen. Iraq has 5,500. Turkey has 4,000, and Syria has little more than 2,800. Egypt's potential is only 1,100. Israel has 460, and Jordan has less than 260. But these are not firm figures, because upstream use of river water can dramatically alter the potential downstream. Scarcity is only one element of the Middle East’s water crisis. Inefficiency is another, as is the reluctance of some water-poor nations to change priorities from agriculture to less water-intensive enterprises. Some experts suggest that if these nations would share both water technology and resources, they could satisfy the region's population, currently 159 million. But in this patchwork of ethnic and religious rivalries, the water crisis is not a clear-cut issue. It is entangled in the politics that keep people from trusting and seeking help from one another. Here, where water, like truth, is precious, each nation tends to find its own water and supply its own truth. 1. When does the rainfall come in the Middle East? 2. What is the cause of the water crisis?

3. How many years are left for Israel and Jordan before their agriculture is threatened?

4. What is the current population in the Middle East according to the passage?

5. According to some experts' suggestion, what should the nations do in order to avoid a water crisis ?

Part B Passage I

Purse snatching is an increasingly common crime. There are estimated 50 to 100 purse snatchings each month in the New York City subways, the number often swinging widely because of the depredations of a single teenager. When such a professional is in custody, the snatches can decrease by more than 50 a month. One of the favored techniques is to stand between two subway cars and, as a train starts pulling out of the station, reach out and pull free a woman's purse.

Recently, a crime analysis officer for the New York Police Department found that purse stealing in Manhattan's top restaurants was up 35 percent over the previous year. When a woman puts her purse on an empty chair at a table or at her feet beside her chair, she is inviting a purse snatcher to take it. Purse snatchers often work in pairs. When a target in a restaurant is seen, one of them will create some kind of disturbance to gain the victim's attention. While the woman is looking away from her table, the actual snatcher will lift the purse. A popular technique is for the thief to carry an umbrella with the curved handle down. The umbrella handle suddenly hooks the bag and in an instant it is on the thief's wrist, or under the coat over his arm if he is a man, and on its way out of the restaurant. Police advise that women in restaurants keep their purse either on their laps or on the floor between their legs.

Other purse snatchers who operate in theaters are called \"seat tippers\victimizing women who put their purses down on a neighboring empty seat. Others specialize in snatching purses from ladies' rooms. When a woman is in a toilet stall, her purse should never be placed on the floor or hung on the coat hook on the door. Thieves simply dive under the door and grab the purse on the floor, or stand on the toilet in the next stall and reach over and take the purse off the hook. The snatcher has enough time to escape since the victim can't immediately pursue the thief. I. 1. When does the number of purse snatchings decrease most dramatically?

Passage II

On the afternoon of July4,1995, Mrs.Beatrice Weinberger brought her one-month old baby back from an outing. She left the pram outside her house and hurried inside to get the baby a clean nappy. When she returned a few moments later, the pram was empty and a scrawled note was lying where her baby had been. The note said: \"Attention. I badly need money, and can't get it any other way. Don't tell the police about this, otherwise I will kill the baby.\" \"Just put $2,000 in small bills in a brown envelope, and place it next to the road lamp at the corner of Albamarle Rd. at exactly 10 o'clock tomorrow (Thursday) morning.\" \"If everything goes smooth, I will bring the baby back and leave him on the same corner 'safe and happy' at exactly 12 noon. No excuse, I can not wait! Your baby-sitter.\" Despite the kidnapper's warning, Mrs. Weinbarger contacted the police. A small parcel containing broken pieces of newspaper was placed on the comer the following morning. But the kidnapper did not show up. He failed to keep two other” appointments\" with the Weinbergers, and left a second note signed \"Your baby-sitter'. By then, the police felt that the baby was no longer alive. The FBI was called in, and the handwriting experts set to work to try to track down the kidnapper. In both notes an unusual z-shaped stroke was placed at the front of the y in words such as \"money\" and \"baby\". Starting with the New York State Police Office, the experts spent the next six weeks carefully going over local records at police offices, factories, hotels, clubs and schools and examining handwriting samples and comparing them with the writing on the kidnapper's notes. Then, in the middle of August, the experts' hard efforts paid off. The handwriting of John Rush Blake matched that of the kidnapper's, especially in the peculiar formation of the y's. Not long after, John Blake was arrested for making illegal alcohol. On being shown the handwriting samples, he confessed to kidnapping the baby. He told the police that he had left the baby alive and well in a nearby park on the day after the kidnapping. But when officers hurried to the place, all they found was the baby's dead body. The criminal was later put into New York's Sing Sing Prison. Even if John Blake had tried to disguise his handwriting he would still have been caught. No matter how hard someone may try to disguise his handwriting characteristics, the \"individuality\" of the writer shows through, the very angle at which he or she holds a pen, the way a t is crossed and an i is dotted, the height and size of capital and small letters, the amount of space between words, the use (or misuse) of punctuation marks. All these can identify a person as surely as fingerprints.

I. 1. What happened to Mrs. Weinberger on the afternoon of July 4th, 1995?

2. According to the message left by the kidnapper, on what condition could Mrs. Weinberger have her baby back?

3. What did Mrs. Weinberger do after reading the note? 4. How did the FBI catch the criminal?

5. Which of the following words can best describe people's handwriting characteristics?

Passage III.

Timothy McVaigh placed a powerful bomb near a federal government building in Oklahoma City in 1995. The explosion killed 168 people, including 19 children. Arguments are increasing in the United States both for and against the death penalty. The increasing death penalty debate is caused by the planned execution of convicted murderer McVeigh. He is to be the first person executed by the federal government since 1963. 38 states permit the death sentence. Last year 85 people were executed in the United States. Recent public opinion studies show that more than 75 percent of Americans supper McVeigh's execution. These include many Americans who usually oppose the death sentence. Kent Scheidegger is with the Criminal Justice Legal Foundation in Califomia. It is a victim's rights organization that supports the death penalty. Mr. Scheidegger says McVeigh is a perfect example of why there is a need for a federal death penalty. He says anything less than the death of McVeigh would show a complete lack of justice. Groups opposed to the death penalty say the approval of the execution of McVeigh does not show an increase in general public support for the death penalty. Opinion studies show that support for the death penalty has decreased. Studies show 77 percent of Americans supported it five years ago, now only about 63 percent do, Opponents of the death penalty have always argued that it was unfair. They say poor people who can not pay for good legal help receive the death penalty more often than others. And they say courts order the death penalty more often when the accused is a member of a racial minority group.

Part B Passage I

The Application of Computers in Education The best method for improving educational standards is to utilize every tool available, including state-of-the-art technology. Computers and the internet have expanded the way in which information can be delivered to the students of today. Today's networking technologies provide a valuable opportunity to practise new learning techniques. Educators are discovering that computers are facilitating learning. Computer-based communications, or telecommunications, can offer many educational opportunities; therefore, educators will need to adapt current teaching methods to incorporate this new media into the classroom. Computers have made a fundamental impact on most industries, providing a competitive advantage that has come to be essential to many businesses. Therefore, schools must also use technology to improve the educational process. School systems often consider purchasing a computer network, and justify its purchase by applying it to routine administrative tasks, such as attendance records and grading. While these tasks are very important, they only show a small part of what technology can do for a school. Technology must go further than simply keeping attendance; it must focus on keeping students interested and productive. Since computers and the Internet have expanded the ways in which education can be delivered to students, it is currently possible to engage in \"distance education\" through the Internet. Distance education involves audio and video links between teachers and students in remote areas. Video conferencing allows groups to communicate with each other. Desktop video conferencing promises to bring students together from geographic and cultural distances face to face via computer. Not only will the teacher talk to the students, but the students will be able to interact with each other. This will make students more interested in learning.

I. 1. According to the passage, what are educators discovering? 2. What do schools usually purchase computer networks for?

3. According to the author, what should computers be mainly used for? 4. Which of the following is NOT a feature of video conferencing? 5. Which of the following is true according to the passage?

II. fundamental impact; be essential; improve the educational process; justify its purchase; attendance records; what technology can do

Passage II

E-Commerce The Internet, as a means for commerce, did not become reality until the 1990s. Before this time, it was mainly a tool for the army, and a research device for some American universities. Its popularity grew when it proved to be a fast and efficient means to conduct long distance transactions, as well as an effective way to distribute information. The first advantage that e-commerce possesses is speed. With increased speeds of communication, the delivery time is expedited and that

欧阳总创编 2021..02.13

欧阳总创编 2021..02.13

makes the whole transaction from start to finish more efficient. Also, you can find practically any product available for sale on the Internet. Even more significant is the fact that information appearing on the Internet can be changed rapidly. This gives business owners the ability to inform customers of any changes to the service that they are offering. The second advantage of electronic commerce is the opportunity it offers to save on costs. By using the Internet, marketing, distribution, personnel, phone, postage and printing costs, among many others, can be reduced. You can start doing business in cyberspace for as little as $100. The savings, therefore, are tremendous. These funds can then be diverted to marketing and advertising your product or service. Cyberspace knows no national boundaries. That means you can do business all over the world as easily as you can in your own neighborhood. Since the Internet connects everyone in cyberspace, information is transmitted at the speed of sound or the speed of light, depending on your connection. Either way, distance becomes meaningless, which enables you to link to nearly anyone on the globe, and anyone on the globe can link to you. The ability to establish links makes doing business on the Internet attractive to customers in any part of the world. A potential source of trouble is customer concerns with privacy and security. Anything sent over the Internet is sent through several different computers before it reaches its final destination. The concern regarding Internet security and privacy is that unscrupulous hackers can capture credit card or check account data as it is transferred or break into computers that hold the same information. Making a customer feel safe is important when doing business on the Internet. Even though no one can guarantee 100% security when transferring financial information over the Internet, e-commerce is still safer than using credit cards at an actual store or restaurant, or paying for something with the use of a 1-800 number.\"

I. l. Before being used for commerce, what was the Internet mainly used for?

2. Which one of the following is NOT a factor that can make transactions more efficient on the Internet?

3. Why does distance become meaningless in e-commerce? 4. What do customers worry about in e-commerce? 5. What is the main idea of this passage?

II. source; privacy; security; destination; credit card; transferred; feel safe; guarantee; safer than; paying for

PassageIII

Computerized Systems

It was pointed out by a computer wag that a computerized system consists of three subsystems: hardware, software, and jellyware. Hardware is the computer itself -- the collection of slightly impure chunks of silicon dioxide and other metal oxides that sometimes conduct electricity and sometimes don't, but never conduct it very well. Basically, hardware is mostly sand with some metal and some organic plastic material to hold it together. Software consists of the instructions necessary in order for the hardware to do things. The instructions are nothing more than signals indicating that certain pieces of hardware are to turn themselves on or off in specific sequences at specific times in specific areas of the hardware. The basic instructions are written or given in binary terms -- on or off-- and other software elements translate this to and from the more complex language used by the next element in the system. Jellyware is the human being who tells the hardware what to do, who gives the hardware its data, who utilizes the output of the hardware, who writes the software, and who uses the

欧阳总创编 2021..02.13

欧阳总创编 2021..02.13

output of the software. Jellyware itself is a computer consisting of hardware and software. Jellyware is mostly water with specific and small amounts of impurities in certain locations. The jellyware's software is mostly preprogrammed with some RAM that is inputted as a result of experience. Hardware and jellyware differ only in the fact that hardware is made up of crystalline structures while jellyware consists of colloidal structures. The jellyware's operating systems appear to function in the parallel mode while those of the hardware operate in a series mode. However, the output of jellyware is one-channel sequential and series in form. Like hardware, jellyware can do only one thing at a time.

Part B Passage I

The GoldRush One day in 1848, a remarkable discovery was made by a carpenter named Marshall. He happened to pick up some bright yellow particles from the water near his sawmill. Not knowing what they were, he took them to his master Mr. Suffer. Sutter immediately realized the importance of the discovery and sent a man to San Francisco to inform the govemor of it so that he could get permission to found a settlement on both banks of the river. Unfortunately in the beginning, the man did not believe it. Only after a reporter from a weekly newspaper went to Sutter's sawmill to make a report, did the news spread all over the USA, and even to Europe. Within a month, thousands and thousands of people hurried towards California to search for the valuable metal. Soldiers deserted the army, sailors left their ships and all sorts of people gave up their jobs so as not to miss the chance of becoming rich. Large number of Europeans joined in the search, too. Crowds of people, ships and wagon trains rushed to the same destination. This was the California Gold Rush. While this went on, families were broken up, husbands were taken away from their wives and children from their parents. On their way to California, lots of worshippers of gold lost their lives before they got a single particle of it. Some of them ware killed in storms at sea; some could not stand the extraordinary hardships, and died of hunger,

cold or illness. The Gold Rush proved a disaster for Sutter himself. For years he tried to drive the prospectors off his land to keep the entire wealth for himself. The prospectors hated him very much, and did a great deal of damage to his business. All Sutter's houses were burned down and all his family, except for himself, were killed. At the end of his life, he became a beggar, who continually stopped passers-by in the street to tell them that gold is the devil.

Passage II. Functions of Money

There is an ancient rhyme about money which goes like this: \"How many uses does money have? Four. A means, a measure, a standard, a store. \" This rhyme forms an excellent basis for a discussion of the main features and functions of money. Money is a means, it is a means of exchange. It enables us to exchange goods and services. Things valued in terms of money become commodities; they can be bought and sold. Money, whenever it is available, provides the opportunity to obtain useful things or replace old things with new ones. The second thing our rhyme tells us is that money is a measure. It serves as a measure of value. It enables us to measure the value of all kinds of goods and services. The items sold by a large store may be very different from each other, but all without exception can be measured by the same measuring rod, namely money. Two things which are not similar in any way may have the same price. Thirdly, money is a standard of value. This means that money itself possesses a value which can remain approximately constant. To serve as a standard, a thing or a substance must remain fixed and unchangeable in comparison with other things. The amount of money in a country should vary, but it should vary in a regular way. It should correspond to the quantity and value of goods and services available for exchange and circulation in that country; if this quantity and value increases, the amount of money in circulation should be proportionately increased. Finally, money is a \"store.\" We store money just as we store other things. Money does not go bad, though in times of financial crisis it may lose some of its value. It enables us to provide for future needs and situations. When we save money weekly or monthly and deposit it in a bank, our savings serve as a store of value in general; they give us the opportunity to make our choices later instead of making them immediately. When we store money we store the power to choose or to decide, so that we can use this power on future occasions.

Passage III Credit Cards

Americans spend a lot of money in their daily lives. Working people spend money on transportation to and from work and on various expenses throughout the day. Americans enjoy shopping and buy many things that they need and want. They spend a lot of money on entertainment. They buy sports equipment, go to sporting events and do many things that cost money. However, many Americans don't pay with cash or write checks for these things. More and more, they pay for things with credit cards. Credit cards are small, rectangular plastic cards. Banks give these cards to their customers. When the customer buys something at a store, he shows his card at the store. This authorizes the store to charge the bank for the customer's purchase. The bank collects all the charges for each customer. Then once a month the bank requires the customer to pay all the charges for that month. The bank does not force the customer to pay the full amount. It allows the customer to pay for the charges in several payments over a period of time. However, the bank requires the customers to pay high interest on the unpaid part of the charges. In this way the bank allows customers to buy things they can not afford at one time. People can use the card to buy what they want and pay for it over a period of time. They also do not need to carry a lot of money.

Part B Passage I:

The drive from England to Scotland provides the traveler with many pleasant changes of scenery. As it is a fairly long journey, it is good to be able to travel with a friend who can take turns with you at the wheel. A patriotic Scotsman traveling with English friends may tell them they are going to see, in the Highlands, the finest scenery in the world. This may sound exaggerated, but on arriving in the Highlands most people readily agree that the scenery is indeed magnificent. The Highlands are, as the name

欧阳总创编 2021..02.13

欧阳总创编 2021..02.13

implies, the hilly or mountainous region of the country; they form the greater part of the western half of Scotland. On the first night in Scotland tourists may choose to put up at a hotel in the little town of Callander, which is known as one of \"the Gateways to the Highlands\". On the following day they can set out to see the various lakes, or rather \"lochs\aspect of the countryside. When they return to their hotels they will be glad to eat a copious \"high tea\". This is a meal which, in Scotland and many parts of northern England, takes the place of tea and dinner: It consists of one substantial course, such as one would have at dinner, followed by bread and butter, with jam or honey, and some kind of cake or cakes; tea is drunk with the meal, which is taken at about six o’clock in the evening. One has a light supper late in the evening. The next morning many tourists journey on to the west coast. The road twists and turns, dips and climbs, but is not dangerous. The greatest hazard is the black-faced sheep: these animals are as active and impudent as goats, and frequently wander recklessly into the road. The tourists may also see a herd of long-haired Highland cattle, which look savage but are no more so than ordinary cattle. Eventually the road runs parallel with the sea, along a coastline fringed with little islands and made ragged with rocky bays and the deep inlets that are also called \"lochs\".

1.What kind of region are the Highlands?

2. Where might tourists stay on their first night in Scotland? 3. What is meant by \"high tea\"?

4. What is the road to the west coast like?

5. What other animals does a tourist see on the way to the west coast?

Passage Ⅱ:

On the western side of Britain lies one of the most beautiful parts of the British Isles: the Principality of Wales. The Welsh mountains have a beauty which is rugged and forbidding, but the slopes are as green and fertile as the valleys and provide rich pasture for sheep and cows. In central and north Wales, farming is the main occupation, but the valleys of south Wales are very heavily industrialized. Here the wealth of the land lies below the surface in rich coal seams, and the mining villages grew into busy towns around iron and steel foundries, chemical works and oil refineries. Wales is very popular for holidays. Every year, thousands of people spend their summer holidays at the seaside resorts on the North Wales coast or, if they prefer it, enjoy undisturbed peace and quiet in isolated villages remote from town life. Those who like to be energetic will probably choose Snowdonia. This part of the country round Snowdon, the highest peak in the Welsh mountains (and the second highest in Britain), is ideal for climbing and walking holidays. Wales has been called \"The Land of Song\". The Welsh people are famous for their good voices and it is rare to find a village without at least one choir competing in an \"eisteddfod\" or arts festival. The biggest festival of all is the International Eisteddfod held every year in Llangollen in Clwyd. Singers, dancers, musicians and poets come from all over the world to compete for the awards, often wearing colorful national costume. The Welsh girls contribute to the festival gaiety with their national dress-a tall black hat, a scarlet skirt and a starched white apron. The streets of this small country town bustle with the comings and goings of visitors speaking many languages, One of the foreign languages heard will be English, for in North Wales many of the local people speak Welsh as their native tongue. Today, only about a quarter of the Welsh population speak this ancient language as their first language, although many more who use

Passage ISAT Examination

Each year, millions of people around the world apply to study at American colleges or universities. The most widely used college admissions test is called the SAT. More than 3,000,000 of the tests were given in 2001.

The SAT was first used for college admissions in 1926. Its purpose was to help college officials identify which students would be successful in college.

Critics say the test has not always done this. Research suggests that students from rich families do better on the SAT than students whose parents are poor. For example, many rich students are able to improve their scores on the test after taking costly preparation classes.

Critics also say many African-American and Hispanic teenagers score lower on the test than students of other ethnic groups.

The College Board is a non-profit higher education association that owns the SAT.

欧阳总创编 2021..02.13

欧阳总创编 2021..02.13

It recently announced major changes in the test. It says the new SAT will better test a student's reasoning and thinking skills. Education experts say the new test will show how well students have learnt material taught in high school.

The first change will end analogy questions on the SAT. Analogies are words with meaning that are linked. Critics have said that such questions show only a knowledge of words, not reasoning skills. The analogy questions will be replaced with questions that better show the student's reading ability. The second major change will add higher level mathematics questions. The final change will add a writing test. Students will have about thirty minutes to write about their reactions to question or statement. In 2001, the president of the University of California, Richard Atkinson, called on his school to stop using the SAT as an entrance requirement. He said the skills it tests are not taught in high school. He said the results of the test do not show if students are prepared to attend college.

College Board officials say those comments caused them to move quickly to change the test. However, they say they had been discussing such changes for some time. They say students will begin taking the new SAT in March, 2005. It will affect students planning to enter college in the fall of 2006. 1. What is the SAT?

2. What is the purpose of the SAT?

3. How is the new SAT to be different from the former one?

4. Which of the following is NOT true about the changes of the SAT?

5. Why did the president of the University of California call on his school to stop usingthe SAT as an entrance requirement?

PART II Medical Education

Men and women in the United States who want to become doctors attend four years of college or university. They usually study science intensively. They study biology, chemistry and other sciences. If they do not, they may have to return to college for more education in science before trying to enter medical school. Some students work for a year or two in a medical or research job before they try to seek a place in a medical college.

There are 125 medical colleges in the United States. More than 66,000 students are attending medical colleges. It is difficult to gain entrance to them. In 2001, about 35,000 students applied to medical schools in the United States. About 17,000 were accepted. A medical education is very costly. It costs as much as 30,000 dollars for each year.

After entering medical school, students spend the next four years studying only medical sciences. The first two years of medical school are spent mainly in class. The students learn about the body and all its systems. They learn about chemistry and medicines, and they begin studying diseases and how to recognize and treat them. Many students say the first year of medical school is the most difficult. They must remember a great deal of information. For example, many schools require that students remember the names of every bone in the body.

By the third year of medical school, students are ready to use their knowledge to begin helping sick people in hospital. These students work under the guidance of experienced doctors. Students observe the treatment of patients. They also examine patients and advise treatment. As the students watch and learn, they think about the kind of medicine they would like to practice when they become doctors.

During the fourth year of medical school, students begin seeking to enter a

欧阳总创编 2021..02.13

欧阳总创编 2021..02.13

medical training program in a hospital. This training program is called a medical residency. Medical school graduates face strong competition to gain a resident position at the hospitals they want most. Hospitals want the top medical school graduates.

Most states require that a person complete at least one year of medical residency before being permitted to take examinations to practice medicine. Some doctors work for many years as residents in hospitals and the length of the residency depends on which medical field they have chosen.

1. What is required before someone enters medical school? 2. How many medical colleges are there in the US? 3. How much does medical education cost each year?

4. What do many of the students think of the first year of medical school? 5. Which of the following about medical residency is NOT true?

Passage I How to Increase Business Profits

Managers of most businesses want high profits in order to pay high dividends to investors. For this reason, they aim to keep costs as low as possible. They also want to set high prices to gain high revenues. But competition within the industry often prevents them from doing so. Generally, a business will not increase the price of its output if its competitors will not increase their prices. If a business sets its prices higher than those of its rivals, many of its customers will buy the output from its rivals.

An important decision managers make is their choice of input-mix---what combination of capital, labor, and raw materials to use in production. The object is to keep production costs as low as possible. If labor costs are high, for example, a firm may invest in automatic machinery so that fewer workers are needed to accomplish the same task. If labor is cheap, the company may decide to employ extra workers instead of buying a machine to do the job. The combination of inputs that permits a firm to produce its goods or services at the lowest possible cost without reducing quality is called the most productive input-mix.

The goal of keeping production costs low also affects a company's choice of
