閱讀下列短文, 從每題所給的A、B、C、D 四個選項中選出最佳選項。
A
The
One cold day in February, Mr. Garson, a biology teacher, was taking a walk during his lunch break. He passed the old basketball court. “What an ugly sight!” he said, groaning. As he stared at the empty court, he had a vision. He stopped and let the vision take shape in his imagination. In his mind, he pictured something quite different from what he actually saw.
Mr. Garson asked the school board for money to turn his vision into a reality. In April he organized a group of community volunteers to tear up the old basketball court and take it away. Then he persuaded a local farmer to bring truckloads of good topsoil free of charge, which several students spread over the field. A group of parents volunteered to build a new fence around the land. Mr. Garson bought some garden tools. He also bought seeds and young plants. In May students planted tomatoes, potatoes, corn, lettuce, onions, and peppers. In one place they planted a dozen kinds of flowers that would bloom through the summer and fall.
Two students checked the garden and watered it every day. On Saturdays throughout the summer, groups of students gathered to weed (除草) the garden and harvest what was ripe. In September students enjoyed eating fresh produce from the George Washington garden for lunch. Most days there were freshly cut flowers on the breakfast tables. In late fall a local farmer plowed under the garden so that it would be ready for planting again in the spring.
“What a beautiful sight!” Mr. Garson announced a speech at the first school assembly. “It proves that we can change things if we work together toward a common goal.”
56. The best title of this passage is _______.
A. What a basketball court! B. How hard the work is!
C. We need vegetables! D. What a sight!
57. In this selection, the word “battered” means_______.
A. damaged B. repaired C. locked D. high
58. What is one theme expressed in this selection?
A. It takes a lot of hard work to get large donations.
B. It is important to eat a lot of fresh fruits and vegetables.
C. You shouldn’t be discouraged if you don’t succeed right away.
D. One person with a vision can make a big difference.
59. How does Mr. Garson get topsoil for the garden?
A. He buys it. B. The school board supplies it.
C. A local farmer donates it. D. He finds it under the basketball court.

Creativity(創(chuàng)造性)is the key to a brighter future, say education and business experts. Here is how schools and parents can encourage this important skill in children.
If Dick Drew had listened to his boss in 1925, we might not have a product that we now think or as of great importance: a new type of tape. Drew worked for the Minnesota Mining Company. At work he developed a kind of material strong enough to hold things together. But his boss told him not to think more about the idea. Finally, using his own time, Drew improved the tape, which now is used everywhere by many people. And his former company learned from its mistake. Now it encourages people to spend 15 percent of their work time just thinking about and developing new ideas.
Creativity is not something one is just born with, nor is it necessarily a character of high intelligence(智力).The fact that a person is highly intelligent does not mean that he uses it creatively. Creativity is the matter of using the resources one has to produce new ideas that are good for something.
Unfortunately, schools have not tried to encourage creativity. With strong attention to test results and the development of reading, writing and mathematical skills, many educators give up creativity for correct answers. The result is that children can give back information but can't recognize ways to use it in new situations. They may know the rules correctly, but they are unable to use them to work out practical problems.
It is important to give children choices. From the earliest age, children should be allowed to make decisions and understand their results. Even if it's choosing between two food items for lunch, decision-making helps thinking skills. As children grow older, parents should let their children decide how to use their time or spend their money, but not tell them too much if they make the wrong decision. The child may have a hard time, but that is all right. This is because the most important character of creative people is a very strong desire to find a way out of trouble.
60.What did the company where Drew once worked learn from its mistake?
A. They encouraged people to work a longer time.
B. They discouraged people to think freely.
C. They asked people to spend all their work time developing new ideas.
D. They encouraged people to spend some of their work time considering and improving new ideas.
61. Creativity is something_______.
A. that people are born with B. that depends on intelligence
C. that is a way of using what one has learned to work out new problems
D. that is not important at all
62.Why don't schools try to encourage creativity?
A. They don't understand the importance of education.
B. They don't want their students to think about anything
C. They pay too much attention to examination marks, language and mathematical skills.
D. They think it is very important to remember some information.
63.What should the parents do when their children decide how to spend their money? A. Try to help them as much as possible
B. Take no notice of whatever they do.
C. Help them if their decision is wrong, but not too much.
D. Leave them as they are.
C
Geologists have been studying volcanoes for a long time. Though they have learned a great deal, they still have not discovered the causes of volcanic action. They know that the inside of the earth is very hot, but they are not sure exactly what causes the great heat. Some geologists have thought that the heat is caused by the great pressure of the earth's outer layers(層). Or the heat may be left from the time when the earth was formed. During the last sixty years scientists have learned about radium, uranium (鈾), thorium, and other radioactive elements(放射性元素). These give out heat all the time as they change into other elements. Many scientists now believe that much of the heat inside the earth is produced by radioactive elements.
Whatever the cause of the heat
may be, we do know that the earth gets hotter the farther down we dig. In deep
mines and oil wells the temperature rises about
When the melted rock works its way close to the earth's crust, a volcano may be formed. The melted rock often contains steam and other gases under great pressure. If the rock above gives way, the pressure is released.
Then the sudden expansion(膨脹) of the gases causes explosion. These blow the melted rock into pieces of different sizes and shoot them high in the air. Here they cool and harden into volcanic ash. Some of the materials fall around the hole made in the earth's surface. The melted rock may keep on rising and pour out as lava. In this way, volcanic ash and lava build up the mountains that we call volcanoes.
64. The main idea of this passage is the _______.
A. interior (內部) of the earth B. formation of volcanoes
C. results of vocalic action D. work of geologists
65. The cause for the heat in interior of the earth is_______.
A. radioactive elements B. the great pressure of the earth
C. not determined D. the heat remaining from the formation of the earth
66.
If the temperature at the earth's surface is
A. 30 B.
D
In cars of normal design, the petrol system is made up of three parts: storage tanks, a pump and a carburetor(汽化器).
The petrol tank is fitted at the back of the car where it is out of the way, yet easily filled at a gas station. Tanks are in various capacity but they usually hold enough petrol for 250~300 miles running. Because the tank is at the opposite end of the car from the carburetor, which is fitted high up on the engine, a pump is needed to draw the petrol from one to the other, as it is from the carburetor that the petrol in finally fed into the engine. Pumps can be of two kinds: electrically operated or mechanically driven from the engine.
67. Which of the following pictures shows the correct petrol system described in this passage?
