题目内容

  Deserts are found where there is little rainfall or where rain for a whole year falls in only a few weeks' time. Ten inches of rain may be enough for many plants to survive (存活)if the rain is

spread throughout the year, If it falls, within one or two months and the rest of the year is dry, those plants may die and a desert may form.   

     Sand begins as tiny pieces of rock that get smaller and smaller as wind and weather wear them down. Sand dunes (沙丘) are formed as winds move the sand across the desert. Bit by bit, the

dunes grow over the years, always moving with the winds and changing the shape. Most of them are only a few feet tall, but they can grow to be several hundred feet high.

There is, however, much more to a desert than sand. In the deserts of the southwestern United States, cliffs (悬崖) and deep valleys were formed from thick mud that once lay beneath a sea more than millions of years ago. Over the centuries, the water dried up. Wind, sand , rain, heat and cold all wore away at the remaining rocks. The faces of the desert mountains are always changing –-very, very slowly ---as these forces of nature continue to work on the rock.

     Most deserts have a surprising variety of life. There are plants, animals and insects that :have adapted to life in the desert. During the heat of the day, a visitor may see very few signs of living things, but as the air begins to cool in the evening, the desert comes to life. As the sun begins to rise again in the sky, the desert once again becomes quiet and lonely.

Many plants may survive in deserts when__________________.

       A. the rain is spread out in a year           B. the rain falls only in a few weeks

       C. there is little rain in a year               D. it is dry all the year round

Sand dunes are formed when___________________.

       A. sand piles up gradually                B. there is plenty of rain in a year

       C. the sea has dried up over the years       D. pieces of rock get smaller

The underlined sentence in the third paragraph probably means that in a desert there is____________.

      A. too much sand                     B. more sand than before

      C. nothing except sand                D. something else besides sand

It can be learned from the text that in a desert____________.

       A. there is no rainfall throughout the year         B. life exists in rough conditions

       C. all sand dunes are a few feet high      D. rocks are worn away only by wind and heat

【小题1】A

【小题2】A

【小题3】D

【小题4】B


解析:

【小题1】事实细节题,根据第一段第二句“…for many plants to survive if the rain is spread throughout the year”,throughout the year意思是“全年”或“一年中”。

【小题2】事实细节题,根据第二段第二句和第三句“当风吹动沙子穿过沙漠、沙丘就形成了。一点一点沙丘会经过几年而增大”,而A项piles up gradually为“逐渐堆积起来”之意。

【小题3】划线句子意思是“可是,对于沙漠来说,有的不仅仅是沙子”也就是说除了沙子还有其它的自然界的东西让沙漠发生变化,并且本段有所描述。

【小题4】推理判断题,在最后一段中文章描述到“大多数沙漠都生有让人惊叹的生命,在白天,观光者能够看到很少的生命体,白天一片沉寂与荒凉,只有到晚上,沙漠才有了生机”,依此判断选B。

Life in 2060

  Let us suppose it is now about A.D. 2060. Let’s make believe (假装;虚构) it is about sixty years from now. Of course, things have changed and life is very different.

  Voyages to the moon are being made every day. It is as easy to take a holiday on the moon today as it was for the people in 1960 to take a holiday in Europe. At a number of scenic spots on the moon, many hotels have been built. The hotels are air-conditioned, naturally. In order that everyone can enjoy the beautiful scenery on the moon, every room has at least one picture window. Everything imaginable is provided for entertainment (娱乐) of young and old.

  What are people eating now? People are still eating food. They haven’t yet started to take on heir (继承) supply of energy directly as electrical current or as nuclear power. They may some day. But many foods now come in pill form, and the food that goes into the pill continues to come mainly from green plants.

  Since there are several times as many people in the world today as there were a hundred years ago, most of our planet’s surface has to be filled. The deserts are irrigated with water and crops are no longer destroyed by pests. The harvest is always good.

  Farming, of course, is very highly developed. Very few people have to work on the farm. It is possible to run the farm by just pushing a few buttons now and then.

  People are now largely vegetarians (素食者). You see, as the number of people increases, the number of animal decreases. Therefore, the people have to be vegetarians and we are healthier both in our bodies and in our minds, and we know the causes and cure of disease and pain, and it is possible to get rid of diseases. No one has to be ill any more.

  Such would be our life in 2060.
