Today's personal computers are very different from the huge machines that were born during World War II-and the difference isn't only in their size. By the 1970s, these early PCs could not perform many of the tasks that today's computers can. Users could only do mathematical calculations(数学计算) and play simple games. Today PCs are used in many different kinds of ways. At home and at work, we use our PCs to do almost everything. It is nearly impossible to imagine modern life without them.
The earliest computers were not "personal" in any way: They were large and expensive, and they required a team of engineers and other experts to keep them running. One of the first and most famous of these, the Electronic Numerical Integrator Analyzer and Computer (ENIAC), was built at the University of Pennsylvania. ENIAC cost ﹩500, 000, weighed 30 tons and took up nearly 2, 000 square feet of floor space.
ENIAC and other early computers proved that the machines were worth so much money, space and manpower they needed. For example, ENIAC could solve in 30 seconds a problem that could take a team of human "computers" 12 hours to complete. At the same time, new technologies were making it possible to build smaller computers.
But one of the most important of the inventions that make way for the PC revolution was the microprocessor(微处理器). Microprocessors were the size of a nail. They could run the computer's programs, remember information and manage data(数据) all by themselves.
These new ideas made it cheaper and easier to produce computers than ever before. As a result, the smaller, cheaper "microcomputer"-soon known as the "personal computer"-was born. Today, portable computers, smart phones and ipads allow us to have a PC with us wherever we go.
1.What's mainly talked about in the first paragraph? ______
A.An even more relaxing lifestyle without PCs.
B.PCs can be made full use of to do everything.
C.Differences between modern and early PCs.
D.The difficult situation of PCs being born.
2.What do we know about the earliest computers? ______
A.It was easy to control them. B.They took up too much room.
C.Nobody could afford one. D.They were built by universities.
3.Why does the writer take ENIAC for example? ______
A.To predict high technology will make computers smaller.
B.To show computers are really smarter than human beings.
C.To explain why computers could deal with any problem.
D.To prove spending money on early computers was meaningful.
4.Which of the following makes the biggest contribution to microcomputers? ______
A.Microprocessors. B.Programs. C.Money. D.Imagination.

New economy online
People are talking about the “new economy”. It’s very different from the “old economy”.
In the old economy, people travel to walk. They buy things in stores. They use the post office, the fax and the telephone to send information. They see people face-to-face at their jobs or in stores. People get information from newspapers, radio, television, books and libraries.
In the new economy, people do business through the “net”, which is a connection of millions of computers everywhere in the world. In the new economy, workers often work at home. They can get information online. They can communicate with employers and co-workers by e-mail . Businesses have “virtual（虚拟的）stores”. They are websites on which customers can see the products. Business can sell to customers anywhere in the world.
In the new economy, people live a fast paced, convenient and colorful life. The whole world develops more quickly than before. But the new economy is double-edge sword(双刃剑).Its disadvantage is also obvious. For example, the Internet has led to a huge increase in credit care(信用卡)cheating. Some illegal websites offer some cheap or banned(禁止的) goods or services. Online shoppers who enter their credit card information may never receive the goods they want to buy and their card information could even be for sale in an illegal website. So people in the new economy should be smarter and knowledgeable.
68.The cause of the differences between the new economy and the old economy is ______.
A. the change of people’s idea B. the business people do
C. the use of the Internet D. the change of people’s life
69.In the old economy, people can do the following things EXCEPT______.
A. getting information from books
B. communicating with friends by telephone
C. meeting people face to face
D. shopping online
70.“But the new economy is a double-edge sword.” in the last passage means______.
A. the new economy is as sharp as a sword
B. the new economy has advantages and disadvantages
C. the new economy is better than the old economy
D. both the new economy and the old economy have disadvantages
71.Which of the following is NOT true?
A. People can get all kinds of information on the Internet.
B. Telephone, radio, television, newspapers and so on will disappear in the new economy.
C. People in the new economy should have high quality.
D. Life in the new economy is more comfortable than the one in the old economy.

In today’s world, we rely on computers as never before. They are used for everything from ordering a pizza to running hospitals and military defense systems. Banking and credit card information is stored and accessed by computers. So what happens when a computer gets infected with a virus? One effect is that people’s access to their e-mail accounts is cut off. A more serious possible consequence is that billions of dollars could be lost.
A virus is a computer program that copies itself onto other programs and infects them. Similar to an easily spread disease, a computer virus goes from computer to computer, either adding to or changing the tasks a program is designed to do.
The first computer viruses were created in the mid’80s and had varying effects. Some caused files to be deleted, or made the letters on the screen appear to fall off. Others displayed a specific message once the computer was turned on.
Viruses today are much more widespread and dangerous than ever before. Perhaps the most damaging has been the “I Love You” virus. “I Love You” appeared in May 2000 and has possibly been the most destructive virus in terms of monetary loss.
The virus is released（释放） when an attachment（附件） to a fake e-mail message is opened. By changing the names of files on computers, “I Love You” makes them difficult to access. It also searches for important personal information, including passwords, which it sends to a Web site for others to see.
It is estimated that more than 45 million people in 20 countries have had their computers infected by the “I Love You” virus. Some say the cost of repair and lost business has been more than US$10 billion.
If you own a computer, it is important to keep it in good health by installing（安装） an anti-virus program. If updated frequently, it will protect your e-mail access-----not to mention your wallet.
51. What does “virus” mean in the article?
A. An easily spread disease.
B. A contagious (传染的) computer program.
C. An extremely small organism（微生物）which causes disease.
D. A parasite（寄生虫）in computer.
52. How dose “I Love You” virus spread?
A. It is spread when an e-mail account is opened.
B. It is spread through on-line chatting.
C. It is spread through e-mail.
D. It spread from web site to web site.
53. Which of the following is one of the damages brought by “I Love You” virus?
A. It deletes files.
B. It automatically turns on computers.
C. It automatically turns off computers.
D. It makes it difficult to access files.
54. Which of the following is the best way to guard against virus?
A. To load an up-to-date anti-virus program into our computer.
B. Not to use an e-mail account.
C. To upgrade our computer.
D. Not to use the Internet.
55. What is the purpose of the article?
A. To warn us against virus.
B. To remind us the importance of being healthy.
C. To stress the importance of computer.
D. To alert us to economic loss.

What makes a person a scientist? Does he have ways or tools of learning that are different from those of others? The answer is “no”. It isn’t the tools a scientist uses but how he uses these tools which make him a scientist. You will probably agree that knowing how to use a power is important to a carpenter. You will probably agree, too, that knowing how to investigation, how to discover information, is important to everyone. The scientist, however, goes one step further; he must be sure that he has a reasonable answer to his questions and that his answer he gets to many questions is into a large set of ideas about how the world works.
The scientist’s knowledge must be exact. There’s no room for half right or right just half the time. He must be as nearly right as the conditions permit. What works under one set of conditions at one time must work under the same conditions at other times. If the conditions are different, any changes the scientist observes in a demonstration(实证) must be explained by the changes in the conditions. This is one reason why investigations are important in science. Albert Einstein, who developed the Theory of Relativity, arrived at the theory through mathematics. The accuracy(正确性) of his mathematics was later tested through investigation. Einstein’s ideas were proved to be correct. A scientist uses many tools for measurements. Then the measurements are used to make mathematical calculations(计算) that may test his investigations
1. What makes a scientist according to the passage?
A. The tools he uses. B. His ways of learning
C. The way he uses his tools D. The various tools he uses
2. “…knowing how to investigation, how to discover information, is important to everyone.”
The writer says this to show ___________.
A. the importance of information
B. the difference between scientists and ordinary people.
C. the importance of thinking
D. the difference between carpenters and ordinary people
3. A sound scientific theory should be one that _________.
A. works under one set of conditions at one time and also works under the same conditions at other times
B. doesn’t allow any change even under different conditions
C. Can be used many times under different conditions
D. Can be used for many purposes
4. What is the main idea of the passage?
A. Scientists are different from ordinary people.
B. The Theory of Relativity.
C. Exactness is the core (核心) of science.
D. Exactness and way of using tools are the keys to making of a scientist.

It is not the tools a scientist uses but how he uses these tools that makes him a scientist. You will probably agree that knowing how to use a power is important to a carpenter. You will probably agree, too, that knowing how to investigate(调查),how to discover information, is important to everyone. The scientist, however, goes one step further, he must be sure that he has a reasonable answer to his questions and that his answer can be confirmed by other persons. He also works to fit the answers he gets to many questions into a large set of ideas about how the world works.
