　　Ⅳ. Reading Comprehension (60 points)

　　Directions: There are five reading passages in this part. Each passage is followed by four questions. For each question there are four suggested answers marked A, B, C and D. Choose one best answer and blacken the corresponding letter on the Answer Sheet.

　　Passage One

　　Many people use wood stoves and fireplaces to heat their homes. Scientists have become worried about the smoke that they give off. Harmful chemicals are in the smoke. The smoke is causing air pollution. The pieces of pollution, called soot, are floating in the air. They are too tiny to see. Scientists must use a microscope to see them.

　　Small amounts of soot are safe, but large amounts can be dangerous. The

　　govenment wants to limit this kind of pollution. It may stop people from using their fireplaces.

　　The air is tested every day. When soot levels are high, more than 65 micrograms of soot per cubic meter, factories must stop making smoke. The government thinks that limit should be much lower.

　　Factories produce the most smoke and soot. But the government thinks that all types of burning should be limited. The soot levels from factories and homes could be limited. Home owners may have to install new wood stoves that they comply with the new law. Or, they may not be able to bum on days when the air quality is bad.

　　Residents of some towns are fined if they violate the burning ban. Scientists hope these new regulations will make the air cleaner and less harmful to breathe.

　　36. Why is it dangerous to burn too much wood?

　　A. The fire could burn you.

　　B. It's not healthy to be too warm.

　　C. Harmful chemicals are released in the soot.

　　D. The smoke is filled with unseeable tiny pieces.

　　参考答案：C

　　37. What could home owners do to comply with the new regulation?

　　A. Write a letter.

　　B. Ask for permission.

　　C. Use more electricity.

　　D. Install new low-soot fireplaces.

　　参考答案：D

　　38. What happens to some residents who bum too much wood?

　　A. They could lose their homes.

　　B. They pay for the punishment.

　　C. They get sick from the smoke.

　　D. The fire could get out of control.

　　参考答案：B

　　39. Why is the air quality tested every day?

　　A. Just in case someone asks.

　　B. Scientists like to take tests.

　　C. Scientists are not very busy.

　　D. To keep track of pollution levels.

　　参考答案：D

　　Passage Two

　　At the first sight the planet Mars does not appear very welcome to any kind of life. It has very little oxygen and water, the temperature at night is below -50~Cand winds of 100 miles per hour cause severe dust storms. However, the surface of the planet seems to show that water flowed across it some time in the past, and it is believed that there is enough ice at the poles to cover the planet with water if it melts. Although there is no life on the Mars now, some scientists think that there may have been some form of life long time ago. At that time, the planet had active volcanoes; the atmosphere was thicker and warmer; and there was water. In fact, in some ways the Mars may have been similar to the Earth, where life exists.

　　Some people believe that the Mars could support life in the future if the right conditions were produced. The first step would be to warm the planet using certain gases which trap the Sun's heat in the planet's atmosphere. With warmth, water and carbon dioxide (二氧化碳), simple plants could begin to grow. These plants could slowly make the Mars more suitable for living. It is estimated that the whole process might take between 100,000 and 200,000 years. In the meantime, people could begin to live on the planet in special closed environments. They would provide a lot of useful information about conditions on the Mars and the problems connected with living there.

　　40. Some scientists think there may have been life on the Mars in the past because __.

　　A. there is no life there now

　　B. there is a large amount of water at the poles

　　C. the Mars may be able to support life in the future

　　D. conditions may have been similar to those on the Earth

　　参考答案：D

　　41. There could be life on the Mars in the future if

　　A. it supported life in the past

　　B. certain gases are used to cool the planet

　　C. the atmosphere can be heated enough to grow simple plants

　　D. the planet's volcanoes become as active as they were in the past

　　参考答案：C

　　42. The author's attitude towards the possibility of life on the Mars in the future is __.

　　A. doubtful

　　B. positive

　　C. negative

　　D. uninterested

　　参考答案：B

　　43. Which is the best title for this passage?

　　A. The Possibility of Life on the Mars

　　B. Future Conditions on the Mars

　　C. The Mars and the Earth

　　D. A Study of the Climate of the Mars

　　参考答案：A
