During recent years, floods and flash floods have caused billions of dollars in damage each year. They are among the most common and widespread of all natural disasters. Even more importantly, they’re No.1 weather-related killer. A flood can happen anywhere along the Mississippi, in New England, even in the desert.
The following are some fascinating facts about floods and flash floods.
A flood（commonly called river flood）is high flow of water from a river or similar body of water, happening over a period of time too long to be considered a flash flood. Flooding is caused in many ways. Winter or spring rains, together with melting snows, can fill rivers too quickly. Heavy rains from hurricanes or other tropical（热带的）systems can also produce river flooding. The Mississippi River Flood of 1993 was caused by repeated heavy rain from thunderstorms over a period of weeks.
Flash floods are quickly-rising floods which are usually the result of heavy rains over a short period of time, often only several hours or even less. They can also be caused by ice jams（冰塞）on rivers related to a winter or spring melting, or occasionally even a dam break. The constant influx（汇集） of water finally caused a great overflow to begin, powerful enough to sweep vehicles away, roll big stones into roadways, uproot trees, level（夷平） buildings, and knock bridges down. The speed of the rising of water is the most frightening.
Do remember: Move to higher ground and stay away from low areas during heavy rain. Stay out of flooded areas. Never allow children especially to play or walk in flowing water. Never drive your car into water of unknown depths.
43. What is the best title for the passage?
A. The power of floods B. The damage of floods
C. The occurrence of floods D. The facts about floods
44. The last paragraph is mainly about ______ .
A. flood safety tips B. the reasons for floods
C. the waste water systems D. the swift flood waters
45. According to the passage, people are afraid of _____ most during flash floods.
A. the constant influx of water
B. the sudden occurrence of flash floods
C. the quick rising water
D. the great damage of flash floods
46. According to the passage, flash floods are ______.
A. great floods resulted from heavy rains in a short time
B. floods rising quickly from heavy rains in a short time
C. quickly-rising floods in a long time
D. floods happening over a long time

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. |
| C．Studying abroad will help students to improve language skills. |
| D．Studying abroad will bring students a lot of difficulties in their life. |
| A．the problems of studying abroad | B．the dream of studying abroad |
| C．the choice of studying abroad | D．the story of studying abroad |
