We have seen that pesticides(杀虫剂)now pollute soil, water, and food, and that they have the power to make our rivers fishless and our gardens and woodlands silent and birdless. Man, however much he may like to pretend the opposite, is part of nature. Can he escape a pollution that is now so thoroughly spread throughout our world?

We know that even single exposure(暴露) to these chemicals, if the amount is large enough, can cause extremely severe poisoning. But this is not the major problem. The sudden illness or death of farmers, farm workers, and others exposed to enough quantities of pesticides is very sad and should not happen. For the population as a whole, we must pay more attention to the delayed effects of taking in small amounts of the pesticides that unseeably pollute our world.

Responsible(负责的) public health officials have pointed out that the biological effects of chemicals are increasing in amount over long periods of time, and that the danger to man may depend on the amount of the exposures received throughout his lifetime. For these very reasons people easily take no notice of the danger. It is human nature to shake off what may seem to us a future disaster(灾害). "Men are naturally most impressed by diseases which have obvious signs," says a wise physician, Dr. Rene Dubos, "yet some of their worst enemies slowly come near them unnoticed."

Which of the following is closest in meaning to the underlined sentence?

A. Man doesn't care about what happens in nature.

B. Man acts as if he does not belong to nature.

C. Man can avoid the effects of environmental pollution.

D. Man can escape his responsibilities for environmental protection.

People are likely to take no notice of the delayed effects of exposure to chemicals because________.

A. limited exposure to them does little harm to people's health

B. the present is more important to them than the future

C. the danger does not become seen clearly and immediately

D. humans are able to bear small amounts of poisoning

It can be concluded from what Dr. Dubos says that________.

A. people find hidden diseases difficult to deal with

B. attacks by hidden enemies are likely to be deadly

C. diseases with obvious signs are easy to cure

D. people are likely to take no notice of hidden dangers caused by pesticides

GU Zhaodi, 60, had taken water for granted for years. In fact, no one in the beautiful lake city of Wuxi, Jiangsu Province had bothered to spare a thought on water.

But all that changed dramatically overnight last month when taps in the city ran dry. Due to a blue-green algae(藻类) outbreak in Taihu Lake, China’s third largest freshwater lake and the source of drinking water for 4 million Wuxi residents(居民),water from the city’s taps became dark and smelly.

“I can’t believe there is no water for drinking, let alone cooking and washing,”said Ｇu.

The lake was blanketed with the algae, giving off a strong smell of rotting meat. A stone thrown into it took a long time to sink. Experts said that algae usually boom because of hot water and rich chemicals like phosphor(磷)in the water.

“High temperature and a lack of rain in the past few months helped the growth of algae,”said Zhang Lijun, an official from the State Environment Protection Administration. “However, pollution from human activity should be most blamed for the disaster.”

Taihu Lake is surrounded by many small factories, whichsprang up in the 1980s.Inthe 1990s,many foreign-funded(外资的) companies joined in. The industries prospered(繁荣)，Wuxi has grown into one of the wealthiest cities in East China.

But that came at the price of pollution. The lake was treated like a waste dump(垃圾堆)，with factories emptying industrial waste and untreated sewage(污水)into it.

Although, after the government's effort, life in the city has gone back to normal, the one-week crisis（危机）rang a bell for the government and local people.“It's time to rebuild the beauty of nature, or our lives will be at risk,”said Gu.

“A safe environment comes first. Economic growth will be nothing without fresh water to drink and clean air to breathe.” said China Daily.
