Noise Pollution
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 be measured in the same way that "noise" is measured
B. may be extremely harmful to health
C. is not at all different from "noise"
D. can be measured by machines
[填空题]pollution control needs the support of technology and techniques
[单项选择] There was one thought that air pollution affected only the area immediately around large cities with factories and heavy automobile traffic. At present, we realize that although these are the areas with the worst air pollution, the problem is literally worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the east of the United States and brought health warnings in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be infected by air pollution. Some scientists consider that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels (coal and oil)is creating a "greenhouse effect" ― conserving heat reflected from the earth and raising the world’’ s average temperature. If this view is correct and the world’’ s temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Bo

How Ozone Pollution Works
Introduction to How Ozone Pollution Works
The weather report on the radio or TV tells you that it is going to be sunny and hot and that an orange ozone alert has been issued. What is ozone What does an orange alert mean Why should you be concerned about it
In this article, we will examine what ozone is, how it is produced, what health hazards it poses and what you can do to reduce ozone pollution.
Ozone is a molecule of three oxygen atoms bound together (O
3). It is unstable and highly reactive. Ozone is used as a bleach, a deodorizing agent, and a sterilization agent for air and drinking water. At low concentrations, it is toxic.
Ozone is found naturally in small concentrations in the stratosphere, a layer of Earth’s upper atmosphere. In this upper atmosphere, ozone is made when ultraviolet light from the sun splits an oxygen molecule (O
2), forming two single
A. Corn starch.
B. Coffee.
C. Filter paper.
D. Potassium iodid

[单项选择]The history of modern pollution problems shows that most have resulted from negligence and ignorance. We have an appalling tendency to interfere with nature before all of the possible consequences of our actions have been studied in depth. We produce and distribute radioactive substances, synthetic chemicals and many other potent compounds before fully comprehending their effects on living organisms. Our education is dangerously incomplete.
It will be argued that the purpose of science is to move into unknown territory, to explore, and to discover. It can be said that similar risks have been taken before, and that these risks are necessary to technological progress.
These arguments overlook an important element. In the past, risks taken in the name of scientific progress were restricted to a small place and brief period of time. The effects of the processes we now strive to maste
A. Unconcerned.
B. Humorous.
C. Serious.

[简答题] Air Pollution
When people think about air pollution, they usually think about smog, acid rain, CFC’’s, and other forms of outdoor air pollution. But did you know that air pollution also can exist inside homes and other buildings It can, and every year, the health of many people is affected by chemical substances present in the air within buildings.
A great deal of research on pollution is being conducted at laboratories and universities. The goals of the research are to find solutions and to educate the public about the problem. Two places where this type of work is being done are LBNL and the University of California, Berkeley. Let’’s take a closer look at the various types of air pollution, the effects that they have on people, and what is being (or not being) done to correct the problem.
What Is Air Pollution
Air is the ocean we breathe. Air supplies us with oxygen which is essential for our bodies to live. Air supplies us with o
