1、英语阅读(二)自考题-18 及答案解析(总分:100.00,做题时间:90 分钟)一、BPART ONE/B(总题数:0,分数:0.00)二、B(总题数:0,分数:0.00)三、BPassage One/B(总题数:1,分数:10.00)Plants and animals that have been studied carefully seem to have built-in clocks. These biological clocks, as they are called, usually are not quite exact in measuring time. However
2、, they work pretty well because they are “reset“ each day, when the sun comes up.Do pigeons use their biological clocks to help them find directions from the sun? We can keep pigeons in a room 1it only by lamps. And we can program the lighting to produce artificial “days“, different from the day out
3、side. After a while we have shifted their clocks. Now we take them far away from home and let them go on a sunny day. Most of them start out as if they know just which way to go, but choose a wrong direction. They have picked a direction that would be correct for the position of the sun and the time
4、 of day according to their shifted clocks.It is known and experimented that homing pigeons can tell directions by the sun. But what happens when the sky is darkly overcast by clouds and no one can see where the sun is? Then the pigeons still find their way home. The same experiment has been repeated
5、 many times on sunny days and the result was always the same. But on very overcast days clock-shifted pigeons are just as good as normal pigeons in starting out in the right directions. So it seems that pigeons also have some extra sense of direction to use when they cannot see the sun.Naturally, pe
6、ople have wondered whether pigeons might have a built-in compasssome- thing that would tell them about the directions of the earths magnetic field. One way to test that idea would be to see if a pigeons sense of direction can be fooled by a magnet attached to its back. With a strong magnet close by,
7、 a compass can no longer tell direction.To test the idea, a group of ten pigeons had strong little magnet bars attached to their backs. Another group carried brass bars instead which were not magnetic. In a number of experiments, both groups were taken away from home and let go. On sunny days none o
8、f the magnet-pigeons was fooled. They were just as good as the brass-pigeons in starting out in the right direction toward home. On cloudy, overcast days, however, with no sun the brass-pigeons chose the right direction, but the magnet-pigeons were in trouble. They later started out in different dir

They are used by all plants and animals to tell time. B. Pigeons biological clocks are regulated every da

They gradually developed as pigeons grow mature.(分数:2.00)A.B.C.D.(3).How can people shift pigeons biological clocks? _ A. By training them when they are young. B. By minor and harmless operations. C. By taking them really fa

They can find directions better than other birds. C. They use the earths magnetic field and the sun to find direc

On heavily cloudy days, pigeons that are not well trained do not fly. B. Pigeons use different sources to find directions on different weather. C. Magnetic

The little magnet bars make it easier for pigeons to find directions.(分数:2.00)A.B.C.D.四、BPassage Two/B(总题数:1,分数:10.00)During his lifetime Alfred Nobel reaped millions of dollars in profits from his invention and manufacture of hi
15、gh explosives. Some of these greatly increased the killing power of weapons and so made war more terrible. Nobel, nevertheless, left much of his fortune for the promotion of world peace as well as the advancement of scientific knowledge and the encouragement of literary achievement.Alfred Bernhard N
16、obel was born in Stockholm, Sweden, on Oct. 21, 1833. Alfred was a sickly child. He was educated at home. Instead of going to high school he traveled widely. He learned chemistry and mechanical engineering in private studies and study abroad. At 21, he joined his father and brother in St. Petersburg
17、. The father had begun some experiments with nitroglycerin but had abandoned them. Alfred resumed these experiments and invented a blasting cap, made of fulminate of mercury, to fire a charge of nitroglycerin. The cap was a very important development.Although still sickly, Nobel took charge of the f
18、amily business. In 1863 he returned to Sweden and set up a small factory to make nitroglycerin. A year later a terrific explosion destroyed the plant and killed five people. One was his youngest brother, Emil. Nobel, how-ever, refused to give up his work and moved the plant to a barge moored in a la
19、ke. Further tragedies occurred. In 1866, after disastrous explosions at world ports, many nations for-bade their vessels to carry nitroglycerin. Nobel then sought to make the explosive safer to handle. He found the answer in dynamite.The invention made Nobel wealthy. He spent the next ten years sett
20、ing up plants in the United States and Europe. In 1876 he patented blasting gelatin, a combination of guncotton and nitroglycerin. In 1878 he and his brothers developed oil fields in Russia. He invented ballistite in 1888, one of the first smokeless powders.Nobel never married. He found recreation i
21、n his laboratory and in writing poetry in imitation of his idol, Percy Bysshe Shelley. In later years he traveled throughout Europe and had homes in Paris, in Stockholm, and in San Remo, Italy. In 1876 he met Bertha Kinsky (later Baroness yon Suttner), a Bohemian noblewoman. In letters to Nobel over
22、 several years she developed his ideas for world peace. Nobels bequest for a peace prize was largely in tribute to her, though he was somewhat doubtful of the effectiveness of the pacifist movement. He died in 1896 at San Remo, leaving the executors of his will to work out the details of administeri
23、ng the Nobel prizes.(分数:10.00)(1).Nobel made a fortune out of _. A. his promotion of world peace B. his advancement of scientific knowledge C. his encouragement of literary achievement D. his invention and manufacture of high explosives(分数:2.00)A.B.C.D.(2).Nobel resumed the experiments his father ha
