6、题数:4,分数:40.00)BDirections:/B There are 4 reading passages in this part. Each passage is followed by some questions or unfinished statements.

7、ith a single line through the center.A scorching sun, an endless sea of sand and a waterless, forbiddingly lonely land-that is the image most people have of deserts. But how true is this picture? Deserts are drylands where rainfall is low. This is not to say rain never falls in deserts. It may fall
8、once or twice a year in a fierce torrent that fades almost as soon as it has begun, or which evaporates in the hot air long before it has got anywhere near the earth. It may fall in a sudden sweeping flood that carries everything in its path. Rains may only come once in five or six years or not fall
9、 for a decade or more. The Mojave desert in the United States remained dry for twenty-five years.Without water no living thing can survive, and one feature of the desert landscape is the absence of vegetation. With little rain and hardly any vegetation the land suffers under the sun. There are virtu
10、ally no clouds or trees to protect the earths surface and it can be burning hot. Under the sun, soils break up and crack. Wind and torrential rain sweep away and erode the surface further. Eight million square kilometers of the worlds land surface is desert. Throughout history deserts have been expa
11、nding and retreating again. Cave paintings show that parts of the Sahara Desert were green and fertile about 10, 000 years ago, and even animals like elephants and giraffes roamed the land. Fossil and dunes found in fertile and damp parts of the world show that these areas were once deserts. But now
12、 the creation of new desert areas is happening on a colossal scale. Twenty million square kilometers, an area twice the size of Canada, is at a high to very high risk of becoming desert. With a further 1.25 million square kilometers under moderate risk, an area covering 30% of the earths land surfac
13、e is desert, becoming desert, or in danger of becoming desert. The rate of growth of deserts is alarming. The worlds drylands which are under threat include some of the most important stock-rearing and wheat-growing areas and are the homes of 600 - 700 million people. These regions are becoming dese
14、rts at the rate of more than 58, 000 square kilometers a year or 44 hectares a minute. In North Africa at least 100, 000 hectares of cropland are lost each year. At this rate there is a high risk that we will be confined to living on only 50% of this planets land surface within one more century unle
15、ss we are able to do something about it.(分数:10.00)(1).What does the passage tell us about rainfall in the desert? A. It never rains. B. It rains so little that nothing can live. C.

19、0)A.B.C.D.The first thing to notice is that the media were all familiar with-from books to television-are one-way propositions: they push their content at us. The Web is two-way, push and pull. In finer point, it combines the one-way reach of broadcast with the two-way reciprocity (互惠) of a mid-cast
20、. Indeed, its user can at once be a receiver and sender of broadcast, a confusing property, but mind-stretching!A second aspect of the Web is that it is the first medium that honors the notion of multiple intelligences. This past centurys concept of literacy grew out of our intense belief in text, a
21、 focus enhanced by the power of one particular technology-the typewriter. It became a great tool for writers but a terrible one for other creative activities such as sketching, painting, notating music, or even mathematics. The typewriter prized one particular kind of intelligence, but with the Web,
22、 we suddenly have a medium that honors multiple forms of intelligence- abstract, textual, visual, musical, social, and kinesthetic. As educators, we now have a chance to construct a medium that enables all young people to become engaged in their ideal way of learning. The Web affords the match we ne
23、ed between a medium and how a particular person learns.A third and unusual aspect of the Web is that it leverages (起杠杆作用) the small efforts of the many with the large efforts of the few. For example, researchers in the Maricopa County Community College system in Phoenix have found a way to link a se
24、t of senior citizens with pupils in the Longview Elementary School, as helper-mentors (顾问). Its wonderful to see- kids listen to these grandparents better than they do to their own parents, the mentoring really helps their teachers, and the seniors create a sense of meaning for themselves.
