Bill Gates was born on October 28th, 1955. He and his two sisters grew up in Seattle. Their father, William H. Gates II, was a Seattle lawyer. Mary Gates, their late mother, was a school teacher.
Gates attended public elementary school before moving on to the private Lakeside School in North Seattle. It was at Lakeside that Gates began his career in personal computer soft- ware, programming computers at age 13.
In 1973, Gates entered Harvard University as a freshman, where he lived down the hall from Steve Ballmer, who is now Microsoft's president. While at Harvard, Gates developed a version (版本) of the programming language BASIC for the first microcomputer---the MITS Astair. In his junior year, Gates dropped out of Harvard to devote his energies full-time to Microsoft, a company he had started in 1975 with his boyhood friend Paul Allen. Guided by a belief that the personal computer would be a valuable tool on every office desk-top and in every home, they began developing software for personal computers.
Gates' foresight has led to the success of Microsoft and the software industry. He plays an important role in the technical development of new products. Much of his time is devoted to meeting with customers and staying in touch with Microsoft employees around the world through e-mail.
In the dozen years since Microsoft went public, Gates has donated more than $ 800 million to charities (慈善機(jī)構(gòu)), including $ 200 million to the Gates Library Foundation to help libraries in North America make use of new technologies and the Information Age.

When Joe Bates was twelve years old, he lost interest in school. He stopped listening in his classes. Some of his teachers began to consider him a problem.
But a few of Joe’s teachers thought that Joe might have lost interest in schoolwork because he already understood it. They proposed that Joe try taking a university class in computer science. Joe did. He was the best student in the class. Later tests showed that his intelligence and knowledge were far greater than most children of his age. He entered university when he was thirteen, about four years earlier than most children. And by the time he was in his early twenties, Joe was teaching computer science at a university.
Joe’s story shows what can happen when a child’s unusual ability is recognized. Sadly, however, not all gifted children get this recognition. And educational experts say unusually gifted children may waste their abilities if they do not get help to develop them.
Studies show that almost twenty percent of students who fail to complete high school in the United States are gifted children.This is because gifted children can have special problems as well as special abilities. Teachers may not recognize their abilities or may not know how to keep them interested. Or they may consider such students to be troublemakers or rebels.
Gifted children may feel lonely or different because they do not know other children who share their interests.
Educators say there are more than two million gifted children in the United States today.  But they say fewer than half are taking part in special education programs designed for them.
One of the most successful programs is held every summer at John Hopkins University in the state of Maryland, where Joe Bates went to school. It started in 1980 when educators saw that there must be many children like Joe.
At first, only 100 children took part in it, and now more than 1,000 children between the ages of nine and sixteen are students in the summer program.
The John Hopkins program provides studies in math and science. It also has classes for children with unusual ability in language and writing. The children study the same subject every day for several weeks. It could be biology, or history, or literature. In those few weeks, they learn as much as in a normal nine-month school year.
William Durden, the director says the program succeeds because it permits children to make progress more quickly than in a traditional program. And the children get to meet others like themselves.
49. Joe Bates stopped listening in his classes because __________.
A. he lost interest in school
B. he hated those teachers who considered him a problem
C. he had already understood what he was taught
D. he wanted to take a university class
50. When a child’s unusual ability is recognized, __________.
A. he can do whatever he likes
B. he will no longer be considered to be a troublemaker or rebel
C. he may have more success than most children of his age
D. he will certainly take part in a special education program
51. According to the passage, the most important thing is to __________.
A. recognize and develop gifted children’s unusual abilities
B. design and support special education programs for gifted children
C. help gifted children get to meet others who share their interests
D. encourage gifted children instead of treating them as a problem
52. Many gifted students fail to complete high school in the United States because _________.
A. they take part in traditional education programs
B. their unusual abilities are not recognized 
C. their teachers don’t know how to keep them interested in schoolwork
D. they have special problems as well as special abilities.

The world is not only hungry, but it is also thirsty for water．This may seem strange to you，since nearly 70 percent of the earth's surface is covered with water．But about 97 percent of this huge amount is sea water, or salt water．Man can only drink and use the other 3 percent-the fresh water from rivers，lakes，underground，and other sources．And we cannot even use all of that，because some of it is in the form of icebergs and glacier．Even worse，some of it has been polluted．
However，as things stand today, this small amount of fresh water is still enough for us．But our need for water is increasing rapidly-almost day by day．Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on．
We all have to learn how to stop wasting our valuable water．One of the first steps is to develop ways of reusing it．
Today in most large cities，water is used only once and then sent out into a sewer system．From there it returns to the sea or runs into underground storage tanks．But it is possible to pipe used water to a purifying plant．There it can be treated with chemicals so that it can be used again，just as if it were fresh from a spring．
But even if every large city purified and reused its water，we still would not have enough．All we'd have to do make use of the vast reserves of sea water in the world is to remove the salt．
If we take these steps we'll be in no danger of drying up．
56．The world is thirsty for water because we can only use      percent of the water covering the surface of the earth．
A．3    B．more than 3    C．less than 3    D．97
57．Which of the following statements is NOT TRUE?
A．As things remain unchanging，this small amount of fresh water is still enough for us．
B．Our need for water is becoming larger and larger．
C．There will be no water shortage in the future．
D．We should take steps to deal with the water shortage problem．
58．To reuse water, we should              ．
A．treat it with chemicals              B．use it only once
C．send it out into a sewer system       D．make it flow into underground tanks
59．In order to have enough water．we should also make use of          ．
A．icebergs and glaciers    B．sea water
C．rivers and lakes        D．underground water

Without plants, people could not live. We eat plants. We take in oxygen that plants make. And we need plants for another reason: We need them because they are beautiful.
Imagine a world with no plants. Imagine no flowers with their sweet smells, their beautiful colours and their lovely shapes. Imagine, when the wind blows, we are not able to hear the leaves of the trees or watch the branches swing from side to side.
Everywhere people need beautiful plants. That is why we have parks full of trees and flowers. That is why people always like houses with room for some grass and a garden.
Do you talk to your plants? Do you give them love and take good care of them? Peter Tompkins and Christopher Bird, writers of a book called The  Secret  of  Plants ,  tell of an experiment in which two seeds were planted in different places. While the plants were growing, one plant was given love and hopeful ideas. After six months, the beloved plant was bigger. Under the earth it had more and longer roots; above the earth, it had a thicker stem and more leaves.
68.In the experiment, the two plants were _____.
A.treated in two different ways    
B. of different kinds

Wash Your Clothes with a Cup of Water?
A washing machine that uses only a cup of water to carry a full wash, leaving clothes completely dry, has been developed by British inventors. Researchers say the technology, which uses less than 2 percent of the water and energy of a traditional machine, could save billions of liters of water each year.
The machine works by using thousands of plastic chips— each about half a centimeter in size—to absorb and remove dirt. Around 20 kilos of the chips are added to each load, along with a cup of water and detergent（洗滌劑）. During the washing cycle, the water is heated to help dissolve the dirt, which is then absorbed by the plastic chips. The inventors say the chips should be removed at the end of each wash, but can be used up to 100 times.
The technology, called Xeros, is already being compared to the Dyson bagless vacuum cleaner, which revolutionized the home cleaning industry when it was first introduced to the public in the mid-1990s.
If adopted by many homes across the UK, the machine could save billions of liters of water each year. According to the research, washing machine use has risen by 23 percent in the past 15 years, up from three times a week in 1990 to an average four times now. The average UK household uses most 21 liters of water daily on clothes washing. Nationally, this equals to approximately 455 million liters of water a day — enough to fill 145 Olympic-sized swimming pools.
Although the Xeros is now in the design and testing stage, the inventors say they are in talks with a commercial partner. The machine could be in the market as early as next year. Tests have produced quite astonishing results. “We’ve shown that it can remove all sorts of everyday stains including coffee and lipstick while using a tiny fraction of the water used by traditional washing machines,” said one of the inventors.
An expert said, “This is one of the most surprising and remarkable technologies I’ve had in recent years. Xeros has the ability to save billions of liters of water per year and, we believe, the potential to revolutionize the global laundry market.
64. Compared with the traditional washing machine, the most outstanding feature of the Xeros is that _________.
A. it doesn’t need any detergent
B. it saves a large amount of water
C. it can remove all sorts of everyday stains
D. the plastic chips can be removed at the end of each wash
65. The writer supports his idea with __________ in Paragraph 4.
A. examples    B. words    C. data     D. imagination
66. What do we know about the Xeros from the passage?
A. It will be quite cheap as the plastic chips can be used up to 100 times.
B. It’ll take the place of the Dyson bagless vacuum cleaner in future.
C. The plastic chips play an important role in absorbing and removing the dirt.
D. It isn’t in the market now because no investors are willing to develop it.
67. What is the writer’s attitude toward the new technology in this passage?
A. Positive.        B. Opposed.       C. Indifferent.    D. Doubtful.

第三部分:閱讀理解
What happens to old school buses when they can no longer safely carry kids to school? Most go to waste factories to be changed into pieces of metal. But a few of the old vehicles (車輛) find new lives in the center of Africa. Most of those buses end up on the streets of Kinshasa, the capital of the Democratic Republic of Congo.
The Kinshasa buses are that yellow color, which makes them stand out (突出) in the city’s heavy traffic, but the buses don’t look at all as they did in the United States. In Kinshasa their taillights(尾燈) are almost all missing or broken. They don’t obey traffic rules and often race around the city very fast. The buses compete with motorcycles, cars, trucks, and other vehicles for space on the road. They make loud sounds when moving, and they are packed with people carrying loads of goods, such as fish, milk, beans and onions.
However, Kinshasa business people love the old, yellow buses, which they buy from American companies, because the vehicles are strong, reliable (可依靠的) and inexpensive. A used bus sells for about $2,000 in Congo. A new bus is more expensive. In the United States, a new school bus with all its lights working costs about $80,000.
The fare (票價(jià)) to travel across the city is usually about 30 US cents. “Transport is a big problem in Kinshasa,” says passenger Bruce Kingambo. “But the yellow buses help people here get around.”
56．The underlined sentence in the first paragraph means “In the center of Africa some old US     school buses can be_________.”
A．useful                     B．expensive                C．free                        D．new
57．Before the school buses leave America for Congo, they_________
A．have broken taillights
B．don’t obey the traffic rules and move at full speed
C．carry many people and goods
D．don’t compete with other vehicles
58．How many used buses can you buy in Congo for the price of a completely new school bus     in the USA?
A．10.                         B．20.                         C．30.                         D．40.
59．The passage mainly tells us _________
A．how to use old school buses
B．a(chǎn)bout new lives for old school buses
C．to try to take old school buses
D．how to drive old school buses
