People have worried about smog for many years, and the government has spent billions of dollars to try to clean up the air of big cities. Now we find that there is no escape from unhealthful air. Recent studies have shown that air inside many homes, office buildings, and schools is full of pollutants; chemicals, bacteria, smoke, and gases. These pollutants are causing a group of unpleasant and dangerous symptoms that experts call "sick building syndrome". A "sick building" might be a small house in a rural area or an enormous office building in an urban center.
A recent study reached a surprising conclusion: Indoor air pollution is almost always two to five times worse than outside pollution! This is true even in buildings that are close to factories that produce chemicals. The solution to this problem would seem very clear; Open your windows and stay out of modern office buildings with windows that don’t open.
Unfortunately, the solution might not be so simple, better ventilation—a system for moving fresh air—can cut indoor air pollution to a safe level, but lack of ventilation is seldom the main cause of the problem. Experts have found that buildings create their own pollution. Imagine a typical home. The people who live there burn oil, wood, or gas for cooking and heating. They might smoke cigarettes, pipes, or cigars. They use chemicals for cleaning. They use hundreds of products made of plastic or particle board; these products—such as the shelves in Oakland High School— give off chemicals that we can’ t see but that we do breathe in. And in many areas, the ground under the building might send a dangerous gas called radon into the home. The people in the house are breathing in a "chemical soup" , and medical experts don’t yet know how dangerous this is for the human body.
Which of the following statements can be concluded from the passage?
选项
A、Sick building syndrome is a sort of disease that is incurable.
B、There is no air pollution in modern office buildings.
C、Few people have realized the danger and harm of indoor air pollution.
D、Chemicals should not be allowed to be produced so as to avoid sick building syndrome.
答案
C
解析
录音讲到“sick building syndrome”是最新研究发现的,而且medical expels还不是很清楚室内污染对人体有多大危害。由此可推测出目前很少有人意识到室内污染的危害。
