[单项选择]Automobile exhaust is a serious pollution problem in Riverside, and instituting tolls at Riverside’s bridges would reduce the total number of miles traveled by automobiles. Nevertheless, overall pollution levels would not decrease because there would be long lines at the toll booths, and automobiles expel more exhaust per minute while idling than in any other driving situation.
The argument above depends on which of the following assumptions
A. Any reduction in automobile exhaust resulting from a reduction in the miles traveled by cars would be matched or surpassed by the additional exhaust resulting from toll lines.
B. Cars in Riverside spend more time, on average, idling than they do in other driving situations.
C. Increasing automobile exhaust at the bridges will not significantly affect air pollution because few drivers use the bridges in Riverside frequently.
D. Reducing automobile exhaust is not the most effective way of reducing air pollution.
E. (E) The inconvenience of idling in the long toll lines at Riverside’s bridges wilt cause most drivers to change their driving routes, not the amount of driving that they do.

[填空题]Pollution from rail transport is usually measured from the motor exhaust.

Psychologists now believe that noise has a considerable effect on people’s attitudes and behavior. Experiments have proved that in noisy situations (even temporary ones), people would have more irritability (躁易怒) and less cooperation. In more permanent noisy situations, many people cannot work hard, and they suffer from severe anxiety as well as other psychological problems. Some researchers, who study various aspects of effect of noise in people’s mental life, maintain that noise, either temporary noise or permanent noise, often destroy creativity and activity by disturbing people’s emotion and make them more irritable and hard to cooperate.
However, psychologists distinguish between "sound" and "noise". "Sound" is measured physically in decibels (分贝). "Noise" cannot be measured in the same way because it refers to the psychological effect of sound and its level of "intensity" depends on the situation. Thus, for pass
A. can not complete his work in a noisy situation
B. will suffer from complete deafness because of noise pollution
C. can be psychologically affected by working in very noisy factories
D. may cooperate well in a noisy surrounding

[填空题]Energy use and air pollution have been synonymous in China for decades, especially in urban areas. (66) Fifteen or 20 years ago in China’s northern cities, such as Shenyang, air pollution was characterized by decreased visibility caused by high levels of particulates and sulfur dioxide (SO₂). Although conditions have improved in modern cities, such as Beijing and Shanghai, China still has three of the ten most polluted cities in the world and hundreds of cities that are not in compliance with the World Health Organization (WHO) air quality guidelines.
(67) More than 120 cities have populations of more than one million, and by the end of the twenty-first century, 10 to 20 cities will have populations of more than 10 million. Rapid urbanization will challenge governments at all levels, not only to provide basic services to growing urban populations, but also to modernize, to continue to develop economically, and to address environmental concerns, particular

Scientists claim that air pollution causes a decline in the world’s average air temperature. In order to prove that theory, ecologists have turned to historical data in relation to especially huge volcanic eruptions. They suspect that volcanoes effect weather changes that are similar to air pollution.
One source of information is the effect of the eruption of Tambora, a volcano in Sumbawa, the Dutch East Indies (the former name of the Republic of Indonesia), in April 1815. The largest recorded volcanic emption, Tambora threw 150 million tom of fine ash into the stratosphere. The ash from a volcano spreads worldwide in a few days and remains in the air for years. Its effect is to turn incoming solar radiation into space and thus cool the earth. For example, records of weather in England show that between April and November 1815, the average temperature had fallen 4.5°F. During the next twenty-four months, England suffered one of the coldest periods of its history
A. Volcanic eruptions
B. Mountain torrents
C. Crop and livestock production
D. The floods after the storm
