Business firms look for the perfect price at which the largest profits（利润）can be made．If the price of the shoes goes up to 50，the consumers（消费者）will not buy all of 3，000 shoes．The producers will have a surplus（剩余）of 2，000 shoes and they can only get 50，000．If the price of the shoes is lowered to10，as many as 5，000 shoes can be sold．Still，only 50，000 is made．

Before the widespread use of computers, managers could not make full use of large amounts of valuable information about a company’s activities. The information either reached managers too late or was too expensive to be used. Today, managers are facing a wide range of data processing and information instruments. In place of a few financial controls, managers can draw on computer-based information systems to control activities in every area of their company. On any kinds at performance measures, the information provided by these systems helps managers compare standards with actual results, find out problems, and take corrective action before it is too late to make changes.
The introduction of computerized information systems has sharply changed management control in many companies. Even a neighborhood shopkeeper may now use computers to control sales and other activities. In large companies, electronic data processing systems monitor entire projects and sets of operations.
Now, there are about 24 million microcomputers in use in the United States, one for every 10 citizens. It is estimated that by 1996, 61 percent of American managers will be using some sort of electronic workstation. In order for managers to be sure that the computer-based information they are receiving is accurate, they need to understand how computers work. However, in most cases they do not need to learn how to program computers. Rather, managers should understand how computerized information systems work; how they are developed; their limitations and costs; and the manner in which information system may be used. Such an understanding is not difficult to achieve.
One research found that business firms were more successful in teaching basic information about computers to business graduates than they were in teaching business subjects to computer science graduates.
46. In the second paragraph the author mentions a neighborhood shopkeeper to show that _____.
A. few people could afford a computer
B. computer is now becoming more and more widely used in business
C. only shopkeepers are wealthy enough to buy computers
D. computer is far more intelligent than man as far as business is concerned
47. From the third paragraph we learn that ________.
A. it is essential that managers know how to program computers
B. managers may sometimes receive inaccurate information from computers
C. in most companies, an employee has to share a computer with at least 9 other employees
D. computerized information system is perfect in every way
48. All of the following statements are true EXCEPT that _________.
A. computer science graduates are quick to learn business subjects because of their professional knowledge about computers
B. with the help of computers, company mangers are now more informed of what’s going on in their companies
C. computer is a great help for business management
D. computerized information enables managers to take timely measures to prevent possible mistakes
49. According to the passage, which of the following statements is right?
A. It’s a difficult task for the managers to deal with a wide range of computer-based information daily.
B. The introduction of computerized information system is a revolution in management
C. In order to perform good management, managers need to have much knowledge about computer.
D. A good knowledge of computer leads managers to success
50. What is the passage mainly about?
A. How to teach information about computers to business graduates.
B. Computer’s growing popularity nationwide.
C. Application of computer in business management.
D. Computer training program for mangers.
It’s true that studying abroad can help students develop themselves. Language skills will improve and it may be easier to find jobs.
But there are problems that should be considered. Language is the first. Students must spend a lot of time learning another language and getting used to a different culture.
Students must also learn to live without parents’ care and deal with all kinds of things they haven’t had to do before, like looking after themselves. There are reports about Chinese students abroad sinking into an ocean of difficulties and giving up easily. When they have to take care of themselves, it is hard for students to study well.
Finally, studying abroad brings a heavy burden(负担) to the family. For most Chinese parents, the cost of studying abroad is very high. But is it worth it?
We know that there are many famous people who succeed in great things through their hard work in China. Liu Xiang is a good example. Once an American teacher invited him there but he refused. He kept training hard with his Chinese teacher. He surprised the world when he won a gold medal at the Athens Olympics. So when you wonder which country is better to study in, consider whether studying abroad is the right choice.
小题1:The writer thinks should be considered first before students study abroad.
| A．places | B．time | C．money | D．language |
| A．Chinese teachers are better than American ones | B．studying abroad is not the right choice |
| C．people can also be successful in China if they work hard | D．Liu Xiang was a gold medal winner |
| A．Studying abroad will cost students’ families a lot of money. |
| B．Studying abroad will make it easy for students to learn well. |

Of course, the good of oxen is not limited to plowing. In fact, they are seen as "boats on land" for their ability to carry loads. Besides, the whole body of an ox is full of treasures. Their meat and milk are food full of nutrition, and their skin can be used to make clothes and shoes. With all these qualities, oxen are regarded as generous creatures.In the past, oxen played an important role in the spiritual life of the Chinese. Even today, oxen still play a special part in some folk activities. For example, some people who1ive in southwest China will cook cattle bone soup and share it among family members when holding the ceremony for children who reach 13. They believe that the cattle bone soup represents the blood relationship among family members. In order to express their love for oxen, people in some other areas will run to shake off diseases on the 16th day of the first month by the lunar calendar （农历）, and during their run they will take their oxen along, which indicates they regard the creature as human.Because of the contribution of oxen in their lives, the Chinese people are very grateful to the animal. In addition, the use of oxen in ceremonies and the thanks people owe to oxen help to develop various traditional customs, which becomes an important part of the folk culture of the Chinese nation.小题1:The words "boats an land" underlined in Paragraph 2 refer to _ .
