Each year there is an increasing number of cars as millions of new cars are produced in America . Americans will not live without cars ! However , some have realised the serious problem of air pollution by cars . It is necessary to find ways to solve the problem of air pollution .
One way to clean the air is to build a new kind of clean car . That’s what several of the large car factories are trying to do . But to build a clean car is easier said than done . Progress in this field has been slow .
Another way is to take the place of the car engine by something else . Engineers are now working on it . Many makers believe that it will take years to develop a practical model that can please man .
To prevebt the world being polluted by cars , They have to cut down on the number of their cars and are encouraged to travel and go to work by bike . But this change doesn’t close down ---- many workers may find themselves without jobs if a car factory closes down . And the problem of their pollution would become less important than that of unemployment.

It is believed that it took about 800 thousand to 1 million years for the earth's population to reach the 250 million total which existed at the end of the first century AD. For some time after that, disease, famine(饥饿) and war kept the population increase down to a rate of 1 percent a year so that more than 15 centuries passed before the population reached 500 million. But in the next 250 years, up to 1850, the population of the world shot to 1 billion and today it has reached 3.5 billion. Scientists say that in the next 35 years the population of the world will double, reaching almost 7 billion by the year 2010.
When experts are asked what are the most effective measures that can stop over population, they reply that at least three measures can be considered.
(A) Increasing sources and supply of food for under-developed countries.
(B) Increasing the industrialization of under- developed countries.
(C) Controlling birth.
The experts add, however, that none of the above measures can be effective by itself, and that all must be combined into one whole program. They also agree that without controlling of births, any other measures are doomed (注定) to failure.

Some English words are made up of the same part and have different beginnings and different endings, such as import, export, report and transport. All these words, you can see, have the same "port", which come from the Latin word, meaning "to carry" or "to move" from one place to another. And according to the bit at the beginning, which we call the prefix the meaning changes. "Import" means "to carry in" or "to bring into a country", "export", "ex" means "out of", so this word means "to carry out of the country", "re" means "back", so the "report" means "to tell somebody, to bring back information to somebody", "transport", "trans" means "across" and it means "to carry across one place to another".
Let's look at the following words: supporter, reporter, importer and exporter. You can see that in this case these words are nouns which are made up of the verbs plus a suffix, thus meaning a person who completes the verb. So supporter means somebody who supports. A reporter is somebody who reports. Importer is somebody who imports and exporter is somebody who exports, and so on.
1. In the first sentence the word "part" means _______.
A. different beginnings and different endings
B. the same part that has several meanings

D. the same root that has different meanings
2.By adding a prefix or a suffix to a root, we can get a word which has _______.
A. the meaning of a Latin word B. a different meaning
C. the meaning of "in" or "out of" D. a lot of meanings
3.We can get a noun _______. [��Դ:.COM]
A. just by adding "er" to verbs B. by changing a prefix
C. only by adding "er" to a root D. by adding a suffix to a verb
4.According to the passage, if we talk about a man of refinement, you may guess that he must be _______.

C. somebody having bad manners

The World's Largest Insect
This giant insect can be used as a toy.
A child ties one end of a string to a stick and the other end around the "neck" of an insect. Holding the stick, the child lets the insect go. With a loud whirring sound, the insect takes off, pulling the string in a large curve over the child's head. The child laughs as the stick jumps around. The child is African, and the toy is the African Goliath beetle, the largest insect in the world.
The Goliath is a true insect because it has six legs and a body that is divided into three parts. Like all beetles, it has two pairs of wings. The front pair are thick and stiff and protect the back pair, which are soft. It is these soft back wings that make the beetle fly forward. They also cause the loud whirring sound the beetle makes when it flies. To steer, the beetle twists and turns its legs the same way you steer a bike by turning its front wheel.
African children often use the Goliath beetle as a toy. Although it is over 15 centimeters long, it is quite harmless.
1.The African Goliath beetle is _______.
A. the world's largest insect
B. a toy used in many parts of the world
C. the only insect found in Africa
D. the world's smallest insect
2.What made the whirring sound that the child heard?
A. The curved string. B. The beetle's soft wings.
C. The beetle's six legs. D. The beetle's body.

A. makes a whirring sound when it flies B. has both soft and hard wings
C. has six legs and a body with three parts D. can fly
4.When flying, the Goliath steers by_______.
A. turning its soft back wings
B. twisting and turning its hard front wings
C. twisting and turning its legs
D. twisting and turning its whole body
Here is a question I have often asked at dinner parties:
You're on an island with only one other person, your best friend. He's dying of cancer. In his final days, he tells you, "I have 100,000 dollars in a bank back home. When I die, make sure my son goes to medical school." Then he dies. But his son is a no-good playboy who has no interest in going to medical school and will waste that money away in a very short time. But your son is entering college, and he is willing to become a doctor. Which one do you give the money to for medical school?

It doesn't matter when or how much a person sleeps, but everyone needs some rest to stay alive. That's what all doctors thought, until they heard about Al Herpin. Al Herpin, it was said, never slept. Could this be true ? The doctors decided to see this strange man themselves.
Al Herpin was 90 years old when the doctors came to his home in New Jersey. They thought for sure that he got some sleep of some kind. So they stayed with him and watched every movement he made. But they were surprised. Though they watched him hour after hour and day after day. They never saw Herpin sleeping. In fact, he did not even own a bed. He never needed one.
The only rest that Herpin sometimes got was sitting in a comfortable chair and reading newspapers. The doctors were puzzled by this strange continuous sleeplessness. They found only one answer that might explain his condition. Herpin remembered some talk about his mother having been injured several days before he was born. But that was all. Was this the real reason ? No one could be sure. Herpin died at the age of 94.
