Read the passage and complete the blanks This summer, heavy rains have caused huge floods which have killed more than 1,000 people and left more than 1 million homeless in China and Eastern Europe. Scientists at the Earth Summit said that these natural disasters were a wake-up call for human beings to act more quickly to stop the planet from becoming too hot. The United Nations has made the environment one of the key areas for discussion at the summit in Johannesburg, South Africa. About 65,000 people from 185 countries are attending the meeting, which is being held from August 26 until September 4. Scientists say that many things that humans have been doing over the past 100 years, such as deforestation (采伐森林) and sending greenhouse gases into the atmosphere, have changed the climate of the earth. Robert Watson, the UN's leading scientist, believes the earth's temperature could rise by up to 5.8 degrees centigrade over the coming century. This summer the central and southern China have faced floods due to deforestation and soil erosion (水土流失). On the other hand, much of the country is suffering from drought. The very serious water shortages, the worst in the past 100 years, have hit about 1 million people in Shandong Province. The region received just half its normal yearly rainfall from June 1 to August 29. Farmers have had to buy water from other places. The Chinese officials at the Earth Summit say greenhouse gases are one of the country's biggest environmental problems. This is because these gases are one of the biggest reasons why there has been such a great change in the earth's climate. As more people use more cars, more gases will be sent into the air, which will cause the earth to get warmer. "The situation will become worse if China doesn't choose the right means of transport," said Liao Xiaoyi, president of the non-governmental group Global Village. "It's very important for China to develop its public transport instead of private cars." Besides climate change, other important issues will be discussed during the summit. They include how to deliver food, water and sanitation to the poor, and how to maintain the biodiversity (保持生物多样化).

Reading A simple piece of clothesline hangs between some environmentally friendly Americans and their neighbors. On one side stand those who see clothes dryers(干衣机) as a waste of energy and a major polluter of the environment. As a result, they are turning to clotheslines as part of the “what-I –can do environmentalism(环境保护主义).” On the other side are people who are against drying clothes outside, arguing that clotheslines are unpleasant to look at. They have persuaded Homeowners Associations (HOAs) access the U.S. to ban outdoor clotheslines, because clothesline drying also tends to lower home value in the neighborhood. This had led to a Right-to-Dry Movement that is calling for laws to be passed to protect people’s right to use clotheslines. So far, only three states have laws to protect clothesline. Right-to-Dry supporters argue that there should be move. Matt Reck, 37, is the kind of eco-conscious(有生态意识的) person who feeds his trees with bathwater and reuses water drops from his air conditioners to water plants. His family also uses a clothesline. But on July 9, 2007, the HOA in Wake Forest, North Carolina, told him that a dissatisfied neighbor had telephoned them about him clothesline. The Recks paid no attention to the warming and still dried their clothes on a line in the yard. “Many people say they are environmentally friendly but they don’t take matters in their own hands,” says Reck. The local HOA has decided not to take any action, unless more neighbors come to them. Environmentalists say such worries are not necessary, and in view of global warming, that idea needs to change. As they say, “The clothesline is beautiful”. Hanging clothes outside should be encouraged. We all have to do at least something to slow down the process of global warming.” (2008ZJJ) 1.

Our city has begun to pay attention to the problem. As far as I know, some rubbish is sorted and sent to different factories. Rubbish, such as old newspapers and glass, is recycled. Some harmful rubbish is sent to a certain place and buried. Waste air is cleaned before it goes into the air. Waste water is treated before it is poured into rivers。 To protect the environment, the government has passed laws to prevent people from throwing rubbish everywhere. We should do our best to take good care of the environment and fight against pollution. |
