【题目】When building houses, people used to think about not only the climate of the areas but also the building materials and the fashions for their houses. However, since electricity became more and more expensive, people began to pay much more attention to the energy they could get for their houses and the new ways they could find to protect their houses from both cold and heat.

Houses of an old yet new type have been widely built. In some parts of the world, people share their houses with their livestock (家畜). During cold weather, they gather their cows, goats, or other animals and keep them on the first floor of their houses. The reasons are that the animals can be protected from the cold and that they can help to heat the houses as well. The body heat given off by the animals rises to the second floor of the houses, where people live. By sharing their houses with their livestock, people gain a source of heat.

People who live in or near cities do not usually keep livestock. However, home builders use the fact that heat rises. This natural law can be used in building houses in these areas. Instead of keeping livestock on the first floor, builders fill it with large rocks. As they are open to the sun’s rays during cold weather, these rocks take in heat. They also give off the heat, and, of course, the warm air rises into the living areas of the houses. So these houses are energy saving.

House building becomes a great challenge to building designers and energy engineers. They try to meet this challenge by learning from old traditions and by using modern technology. And someday in the future, people will be able to live in more energy saving houses.

【1】What did people begin to consider as electricity was no longer cheap?

A.The climate of their areas

3The underlined words “natural law” in the third paragraph refer to the fact that ________.

A.Heat raises the temperature in the houses

B.Heat increases the temperature of rocks

C.Heat goes up if temperature is raised

D.Heat goes in the upward direction

4From the passage, we can infer that __________.

A.People will no longer consider building materials in the future

B.Energy saving buildings will become more popular in the future

C.Almost all people will move into the houses heated by large rocks

D.Energy engineers will devote themselves only to modern technology.

【题目】One thing the tour books don't tell you about London is that 2,000 0f its residents (屠民) are foxes. They ran away from the city about centuries ago after developers and pollution moved in. But now that the environment is cleaner, the foxes have come home.

"The number and variety of wild animals in urban c城市的) areas is increasing," says Corner Jones. A survey of the wildlife in New York's Central Park last year counted 14 kinds of animals. A similar survey carried out in the 1890's counted only five kinds.

Several changes have brought wild animals to the cities. First, the air and water quality in many cities have improved as a result of the 1970s pollution-control efforts. Meanwhile, rural areas have been built up, and many animals have gone to the area outside the centre of a city. In addition, urban wildlife refuges (避难处) have been created. The Greater London Council last year spent $ 750, 000 to buy land and build 10 permanent (永久性的) wildlife refuges in the city. As a result, many birds are now living in the city. By 1970 the birds had died out east of the Mississippi because the DDT had made their eggs too thin to support life.

That year, scientist Tom Cade of Cornell University began raising the birds for release in cities, for cities afforded abundant food.

Cities can attract wild animals without turning them harmful. The key is to create habitats where they are able to live happily. Such habitats can even be useful. In San Francisco, /span>the local government is testing different kinds of rainwater control basins to see not only which ones keep the cleanest water but which will attract the most birds.
