For computer users, there is no bigger excitement than tossing out your old PC and upgrading to a newer, faster and cleaner machine. With hardware designers like Intel, pushing newer, faster products every year, and new software requiring even more powerful machines, companies and consumers have little choice but to go along.

But this rapid turnover is having a serious effect on the planet. Producing a personal computer consumes large quantities of natural resources. A recent study by the United Nations estimates the energy required to produce a single new computer is equivalent to nearly two barrels of oil. And that doesn't include the 22 kg of chemicals or the 1,500 kg of water used in the manufacturing process.

  In fact, pound for pound（均等地）, the process for making a car is about 500% more efficient than that for making a computer. That doesn't matter so much 20 years ago when personal computers were few and far between, but times have changed. These days, computers are found nearly everywhere and sales continue to grow. The number of PCs in use topped one billion in 2002.

Waste in production is only half the problem. Old computers, especially the monitors, are full of dangerous substances, which need to be carefully recycled. The problem is sure to expand over the coming years as users replace their boxy CRT monitors with LCD flat displays.

  Europe now requires that 70% of parts from old computers be recycled, but the study’s authors say that’s also part of the problem. The solution, they insist, is for governments and companies to encourage people to use their computers longer, and upgrade rather than replace. But considering that much of the world’s recent economic growth has come from spending on computers and information technology, that advice may sound like wishful thinking. 

1.What do computer users have to do every few years according to the passage?

   A. Push newer, faster products.

   B. Produce more powerful machines.

   C. Consume large quantities of natural resources.

   D. Upgrade to a newer, faster computer.

2.What does the underlined word “that” in paragraph 3 refer to?

A. The pound.                                   B. The process.

    C. The car.                                     D. The computer.

3.We can infer from the last paragraph that ____.

A. governments and companies will surely encourage people to use their computers longer

B. governments and companies will probably encourage people to replace their personal computers

C. the world's economic has been growing without people's spending on computers and information technology

D. all parts from old computers are now recycled in Europe

4.The purpose of writing this passage is ____

Many famous museums throughout the world can offer you good chances to admire art. Washington, D.C has the National Gallery of Art，Paris has the Louver, London, the British Museum. Florida International University(FIU) in Miami also shows art for people to see. And it does so without a building, or even a wall for its drawings and paintings.
FIU has opened what it says is the first computer art museum in the United States. You don’t have to visit the University to see the art. What you need is just a computer linked to a telephone. That’s enough.
You can call the telephone number of a University computer and connect your own computer to it. All of the art is stored in the school computer. It is computer art, produced electronically by artists on their own computers. In only a few minutes, your computer can receive and copy all the pictures and drawings.
Robert Shostak is director of the new computer museum. He says he started the museum because computer artists had no place to show their work.
A computer artist could only record his pictures electronically and send the records, or floppy discs, to others to see on their computers. He could also put his pictures on paper. But to print good pictures on paper, the computer artist will have  to need a very expensive laser printer.
Robert Shostak says the electronic museum is mostly for art or computer students at schools and universities. Many of the pictures in the museum are made by students. Mr Shostak said the FIU museum will make computer art more fun for computer artists because more people can see it. He says artists enjoy their work much more if they have an audience. And the great number of home computers in America could mean a huge audience for the electronic museum.
【小題1】The main purpose of this text is to give information about____________.

A．famous museums throughout the world
B．a(chǎn)n electronic art museum in Miami, U.S.A
C．a(chǎn)rt exhibitions in Florida International University

If you are planning to study in the United States, you need to consider several factors. Everyone has different opinions about where is the best place to live in. Also, the best places to live are not always home to the best schools. Finally, many schools specialize in different areas of study. The Massachusetts Institute of Technology, for example, is a great school for computer science and technology-related fields of study. However, if you want to study oceanography（海洋學）, your interests may be better served by attending school in a place that is on a coastline or near the ocean.
Now I am sure that you know which schools are considered the best in the country. So I will tell you about which states I believe are the best to live in.
California is a nice state. Northern California specifically has very good weather. Los Angeles in Southern California is another story though. Life in Los Angeles is full of excitement and fast, and sometimes dangerous. As for me, I enjoy the time I spent in Massachusetts, Virginia and Maryland and these states have a lot of history and culture. The weather is not as perfect as California, but it is still quite nice. My favorite area of America is the Mid-west. Middle America, I think, is home to the true American sense of values. In addition, there are many good universities there.
Also, you need to think about your likes and dislikes and then research the various states. You like sunshine and hate snow? Then you probably won’t like the Midwest or even the Northeast. Open space, nature and peace and quiet? Then you probably should stay away from America’s large cities. Are you interested in government? Then Washington D.C. is the only place for you. Whatever you decide, put some thought into it. The place you live could be the difference between a great study-abroad experience and a state of great suffering on earth.
【小題1】From the first paragraph we can conclude （得出結(jié)論）that in the USA _______.

A．a(chǎn)ll colleges and universities lie in big cities
B．a(chǎn)ll colleges and universities lie in beautiful places
C．famous colleges and universities lie in nice places
D．famous colleges and universities may not lie in nice places
【小題2】What should be considered first if you want to study in the USA?
A．The climate.B．The scenery.C．The study condition.D．The living condition.
【小題3】From the third paragraph we can find that _______.
A．California is the best place to live in
B．California is the worst place to live in
C．California is a state with different climates
D．California is a small state in the USA
【小題4】If you study in Middle America, you can probably _______.
A．find the best universitiesB．feel the real character of the nation
C．meet the most famous professors thereD．face more difficulties
【小題5】 From the last paragraph of this passage we can get to know that _______.
A．Washington is the largest city in the USA
B．Washington is the political centre of the USA
C．you can’t find sunshine in the Midwest
D．you can’t find any universities out of big cities in the USA

Last month, students from one hundred and three universities in eighty-eight countries took part in an international computer programming contest, which took place in Harbin, China. Three-person teams from each school had five hours to solve eleven real world problems.

The students first listed the problems in order of difficulty. Then they figured out the requirements of each. They designed ways to test their solutions. And they wrote the needed software systems. Even the winning team from Shanghai Jiaotong University in China was not able to solve all the problems within the given limit. Stanford’s team solved five problems and finished in fourteenth place. Stanford was one of twenty-one American universities that took part in the contest this year.

The official name of the Battle of the Brains is the ACM International Collegiate Contest. The first final competition was held in 1977 at the Association for Computer Machinery Computer Science Conference. Today, a network of universities holds area competitions that send the winners to the world finals, now organized by IBM.

Contest spokesman Dong Heintzman says the world champions receive prizes and scholarships. They are also guaranteed an offer of employment or internship(實習) with IBM. He said, “We have had past world champions that IBM has gone and employed in our Zurich research laboratory and are now working on some of the leading edge materials in science and physics. We have a world finalist from China who’s been working on the Watson Supercomputer that in the near future will be playing Jeopardy(一種超級計算機名稱)against the best Jeopardy players in the world. So this competition is an opportunity to be recognized and to be recruited(招聘) by some of the top technology and research firms around the world.”

1. From the first paragraph we can figure out there were _______ programmers taking part in the contest.

A．3                B．88               C．246              D．a(chǎn) lot of

2. From the last paragraph we know that _______.

A．the winners will be offered a job in IBM
