It was once thought that air pollution affected only the area immediately around large cities with factories and/or heavy automobile traffic. Today, we know 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 entire eastern half of the United States and led to health warnings even in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be affected by air pollution. Some scientists feel that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels(coal and oil) creating a greenhouse effect-holding in 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, Boston, Miami, and New Orleans will be under water.
Another view, less widely held, is that increasing particulate matter in the atmosphere is blocking sunlight and lowering the earth’s temperature-a result that would be equally disastrous（灾难的）. A drop of just a few degrees could create something close to a new ice age, and would make agriculture difficult or impossible in many of our top farming areas. At present we do riot know for sure that either of these conditions will happen(though one recent government report prepared by experts in the field concluded that the greenhouse effect is very likely). Perhaps, if we very lucky, the two tendencies will offset each other and the world’s temperature will stay about the same as it is now.
1.As pointed out at the beginning of the passage, people used to think that air pollution ______.
A．caused widespread damage in the countryside
B．affected the entire eastern half of the United States
C．almost brought worldwide effect
D．existed merely in urban and industrial areas
2.As far as the greenhouse effect is concerned, the author _____________.
A．shares the same view with the scientists
B．is uncertain of its occurrence
C．rejects it as being ungrounded（无根据的）
D．thinks that it will increasingly destroy the world soon
3.It can be inferred from the passage that________.
A．raising the world’s temperature a little would not do much harm to life on the earth
B．lowering the world’s temperature a little would lead to agricultural disasters
C．almost no temperature variations have occurred over the past decade
D．the world’s temperature will remain stable forever
4.This passage is primarily concerned with________.
A．the greenhouse effect in the world
B．the measures to adjust the climate
C．the potential effect of air pollution
D．the measures to protect the environment

It was once thought that air pollution only affected the area immediately around large cities with factories or heavy automobile traffic. Today we know that although these are the areas with the worst air pollution, the problem is actually worldwide. On several occasions over the past ten years, a heavy cloud of air pollution has covered the entire eastern half of the United States and led to health warning even in rural areas away from any major concentration of big factories or automobile. In fact, the very climate of the entire earth may be affected by air pollution. Some scientist feel that the increasing concentration of carbon dioxide in the air resulting from the burning of coal and oil is creating a "green house" effect--holding in 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 will disappear and cities, such as New York, Boston, Miami, and New Orleans will be under water.
Another view, less widely held, is that increasing particulate matter (颗粒物质) in the atmosphere is blocking sunlight and lowering the earth's temperature--a result that would be equally disastrous. A drop of just a few degrees could create something close to new ice age and would make agriculture difficult or impossible in many of our top farming areas. At present we do not know for sure that either of these conditions will happen (though one recent government report prepared by experts in this field concluded that the green house effect is very likely). Perhaps, if we are lucky enough, the two trends will offset each other and the world's temperature will stay about the same as it is now.
1.As far as the green house effect is concerned, the author________.
A. shares the same view with the scientist
B. is not sure that it will happen
C. thinks it impossible because there is no strong evidence
D. thinks it will destroy the world soon
2.According to what we read in the passage, ________.
A. raising the world's temperature only a few degrees would do no harm to life on the earth
B. lowering the world's temperatures only a few degrees would lead many major farming areas to disaster
C. the temperature in the countryside will remain permanent in the years to come
D. the particulate matter in the atmosphere has lowered the world's average temperature
3.The word "offset" in the last sentence means________.
A. strengthen B. worsen C. balance D. support
4.This passage is mainly about________.
A. the pollution caused by human beings B. the green house effect
C. the potential effect of air pollution D. the possibility of a new ice age

Death Valley is one of the most famous deserts in the United States, covering a wide area with its alkali sand. Almost 20 percent of this area is well below sea level, and Badwater, a salt water pool, is about 280 feet below sea level and the lowest point in the United States.
Long ago the Panamint Indians called this place "Tomesha"-- the land of fire. Death Valley's present name dates back to 1849, when a group of miners coming across from Nevada became lost in its unpleasantness and hugeness and their adventure turned out to be a sad story. Today Death Valley has been declared a National Monument and is crossed by several well-marked roads where good services can be found easily. Luckily the change created by human settlement has hardly ruined the special beauty of this place.
Here nature created a lot of surprising, almost like the sights on the moon, ever-changing as the frequent wind moves the sand about, showing the most unusual colors. One of the most astonishing and colorful parts of Death Valley is the Devil's Golf Course, where it seems hard for one to tell reality from dreams. Sand sculptures stand on a frightening ground, as evening shadows move and lengthen.

A. an Indian name B. the death of the miners

A. no one had ever known the desert before the miners
B. it's still not easy to travel across the desert

D. people have changed the natural sight of the desert
