8、 Comprehensio(总题数：4，分数：40.00)Text 1 The dog, called Prince, was an intelligent animal and a slave to Williams. From morning till night, when Williams was at home, Prince never left his sight, practically ignoring all other members of the family. The dog had a number of clearly defined duties, for wh
9、ich Williams had patiently trained him and, like the good pupil he was, Prince lived for the chance to demonstrate his abilities. When Williams wanted to put on his boots, he would murmur “Boots” and within seconds the dog would drop them at his feet. At nine every morning, Prince ran off to the gen
10、eral store in the village, returning shortly not only with Williams daily paper but with a half ounce packet of Williams favorite tobacco, John Rhineys Mixed. A gun dog by breed, Prince possessed a large soft mouth specially evolved for the safe carrying of hunted creatures, so the paper and the tob
11、acco came to no harm, never even showing a tooth mark. Williams was a railwayman, an engine driver, and he wore a blue uniform which smelled of oil and oil fuel. He had to work at odd times “days”, “late days” or “nights”. Over the years Prince got to know these periods of work and rest, knew when h
12、is master would leave the house and return, and the dog did not waste this knowledge. If Williams overslept, as he often did, Prince barked at the bedroom door until he woke, much to the annoyance of the family. On his return, Williams slippers were brought to him, the paper and tobacco too if previ
13、ously undelivered. A curious thing happened to Williams during the snow and ice of last winter. One evening he slipped and fell on the icy pavement somewhere between the village and his home. He was so badly shaken that he stayed in bed for three days; and not until he got up and dressed again did h
14、e discover that he had lost his wallet containing over fifty pounds. The house was turned upside down in the search, but the wallet was not found. However, two days laterthat was five days after the fallPrince dropped the wallet into Williams hand. Very muddy, stained and wet through, the little cas
15、e still contained fifty three pounds, Williams driving license and a few other papers. Where the dog had found it no one could tell, but found it he had and recognized it probably by the faint oily smell on the worn leather.（分数：10.00）(1).How did the dog perform his duties?（分数：2.00）A.He was delighted
16、 to show them off.B.He did his best but was not often successful.C.He did them quickly to get them over.D.He had few opportunities to do them.(2).What does the passage tell us about gun dogs? （分数：2.00）A.They are the fastest runners of all dogs.B.Their teeth are removed when they are young.C.They can

Th
20、ere are different forms of colour blindness. A man may not be able to see deep red. He may think that red, orange and yellow are all shades of green. Sometimes a person cannot tell the difference between blue and green. In rare cases an unlucky man may see everything in shades of greena strange worl
21、d indeed. In certain occupations colour blindness can be dangerous and candidates are tested most carefully. For example, when fighting at night, soldiers use lights of flares to signal to each other. A green light may mean “Advance” and a red light may mean “Danger! Keep back!”, You can see what wi
22、ll happen if somebody thinks that red is green! Colour blindness in human beings is a strange thing to explain. In a single eye there are millions of very small things called “cones”, These help to see in a bright light and to tell the difference between colours. There are also millions of “rods” bu
23、t these are used for seeing when it is nearly dark. They show us shape but not colour. Wait until it is dark tonight, then go outside. Look round you and try to see what colors you can recognize. Birds and animals which hunt at night have eyes which contain few or no cones at all, so they cannot see
24、 colours. As far as we know, bats and adult owls cannot see colours at all only light and dark shapes. Similarly cats and dogs cannot see colours as well as we can. Insects can see ultraviolet rays which are invisible to us, and some of them can even see X-rays. The wings of a moth may seem grey and
25、 dull to us, but to insects they may appear beautiful, showing colours which we cannot see. Scientists know that there are other colours around us which insects can see but which we cannot see. Some insects have favorite colours. Mosquitoes like blue, but do not like yellow. A red light will not att
26、ract insects but a blue lamp will.（分数：10.00）(1).Among people who suffer from colour blindness, .（分数：2.00）A.some may see everything in shades of greenB.few can tell the difference between blue and greenC.few may think that red, orange and yellow are all shades of greenD.very few may think that everyt
27、hing in the world is in green(2).When millions of rods in our eyes are at work in darkness we can see.（分数：2.00）A.colours onlyB.shapes and coloursC.shapes onlyD.darkness only(3).According to the passage, bats and adult owls cannot see colours.（分数：2.00）A.because they hunt at nightB.because they cannot
28、 see lightC.because they have no cones and rodsD.because they have no cones(4).According to the passage, dogs and cats.（分数：2.00）A.as well as human beings can not see some coloursB.have fewer cones than human beingsC.have less rods than human beingsD.can see colours as well as human beings(5).Which o
29、f the following is not true about insects?（分数：2.00）A.Insects can see more colours than human beings.B.Insects can see ultra violet rays which are invisible to men.C.All insects have their favorite colours.D.The world is more colorful to insects than to human beings.Text 3 A child who has once been p
30、leased with a tale likes, as rule, to have it retold in identically the same words, but this should not lead parents to treat printed fairy stories as sacred texts. It is always much better to tell a story than read it out of a book, and, if a parent can produce what, in the actual circumstances of
31、the time and the individual child, is an improvement on the printed text, so much the better. A charge made against fairy tales is that they harm the child by frightening him or arousing his sadistic impulses. To prove the latter, one would have to show in a controlled experiment that children who h
32、ave read fairy stories were more often guilty of cruelty than those who had not. Aggressive, destructive, sadistic impulses every child has and, on the whole, their symbolic verbal discharge seems to be rather a safety valve than an incitement to overt action. As to fears, there are, I think, well-a
33、uthenticated cases of children being dangerously terrified by some fairy stories. Often, however, this arises from the child having heard the story once. Familiarity with the story by repetition turns the pain of fear into the pleasure of a fear faced and mastered. There are also people who object t
34、o fairy stories on the grounds that they are not objectively true, that giants, witches, two headed dragons, magic carpets, etc., do not exist; and that, instead of indulging his fantasies in fairy tales, the child should be taught how to adapt to reality by studying history and mechanics. I find su
35、ch people, I must confess, so unsympathetic and peculiar that I do not know how to argue with them. If their case were sound, the world should be full of madmen attempting to fly from New York to Philadelphia on a broomstick or covering a telephone with kisses in the belief that it was their enchant
36、ed girl friend. No fairy story ever claimed to be a description of the external world and no sane child had ever believed that it was.（分数：10.00）(1).In the writers opinion, a fairy tale .（分数：2.00）A.cannot be read to children without variation because they find no pleasure in itB.will be more effectiv
37、e if it is adapted by parentsC.must be made easy so that children can read it on their ownD.is no longer needed in developing childrens power of memory(2).According to the passage, some people who are openly against fairy tales argue that . （分数：2.00）A.fairy tales are harmful to children in that they
38、 show the primitive cruelty in childrenB.fairy tales are harmful to children unless they have been adapted by their parentC.fairy tales increase a tendency to sadism in childrenD.children who have read fairy stories pay little attention to the study of history and mechanics(3).In the writers opinion
39、 to rid children of fears, fairy stories should be. （分数：2.00）A.told only onceB.repeated many timesC.told in a realistic settingD.presented vividly(4).In the writers opinion, fairy stories . （分数：2.00）A.have a very bad effect on childrenB.have advantages in cultivating childrens imagniativityC.help ch
40、ildren to come to terms with fearsD.harm children greatly(5).According to the passage, which of the following statement is not true about fairy stories? （分数：2.00）A.If children indulged his fantasies in fairy tales instead of being taught how to adapt to reality by studying history and mechanics the
41、world should be full of madman.B.Children can often be greatly terrified when the fairy story is heard for the first time.C.Fairy tales may beneficially direct childrens aggressive, destructive and sadistic impulses.D.Fairy tales are no more than stories about imaginary figures with magical powers w
42、hich has nothing to do with external world.Hadley If you smoke and you still dont believe that theres a definite link between smoking and bronchial troubles, heart disease and lung cancer, then you are certainly deceiving yourself. Just have a look at those people in hospital with these diseases and
43、 count how many of them do not smoke, you may be surprised at the number. Even these few people might be passive smokers without realising it. Randy Tobacco is a wonderful commodity to tax. Its almost like a tax on our daily bread. In tax revenue alone, the government of Britain collects enough from
44、 smokers to pay for its entire educational facilities. So while the authorities point out ever so carefully that smoking may be harmful, it doesnt do to shout too loudly about it. Sampson The advertising of tobacco is one of the problems. We are never shown pictures of real smokers coughing up their
45、 lings early in the morning. That would never do. The advertisements always depict handsome, cleanshaven young men. They suggest it is manly to smoke, even positively healthy! Smoking is associated with the great openair life, with beautiful girls, true love and togetherness. What utter nonsense! Ro
46、wley Of course tobacco can help government to raise money. However, while money is eagerly collected in vast sums with one hand, it is paid out in increasingly vaster sums with the other. Enormous amounts are spent on cancer research and on efforts to cure people suffering from the disease. Countles
47、s valuable lives are lost. In the long run, there is no doubt that everybody would be much better off if smoking were banned altogether. Bernice Smoking can provide constant consolation. When I feel worried or nervous, I just get a cigarette and everything seem to get right. After a days hard work,
48、the thing I want to do most is smoking. It can be even better with a cup of coffee. Its so enjoyable and relaxing that it relieves stresses of every day life. So why bother to ban it and take the pleasure from us. Now match each of the people (1 to 5) to the appropriate statement. A Smoking brings m
49、any psychological benefits. B Tobacco is an important source of income to the government. C Smoking is sure to cause diseases. D Its a shortsighted policy to depend on tobacco for money. E The advertisement for it is dishonest and harmful. F The tobacco industry makes highquality advertisement for smoking. G Its doubtful whether there is link b
