单项选择题
1、根据以下内容回答题：
Many things about language are a mystery，and many will always remain so.But sone
things we do know．
First，we know that all human beings have a language of some sort．Thero is no race of men anvwhere on earth so backward that it has no language，no set of speech souBds by whieh the people communicate with one another．Furthermore，in historical times，there has never been a race of men without a language．
Second．there is no such thing as a primitive language．There are many people whose cal-tures are undeveloped，who are，as we say，uncivilized，but the languages they speak are not Drimitive．In all known languages we can see complexities that must have been，tens of thou-sands of years in developing.
This has not always been well understood；indeed，the direct contrary has often been stated．Popular ideas of the language of the American Indians will illustrate．Many people have supposed that the Indians communicated in a very primitive system of noises-Study has proved this to be nonsense．There are，or were，hundreds of American Indian languages，and all of them tum out to be very complicated and very old．They are certainly different from．the lanlguages that most of us are familiar with，but they are no more primitive than English and Greek.A third thing we know about language is that all languages are perfectly adequate．That is，each one is a perfect means of expressing the culture of the people who speak the language.
Finallv，we know that language changes．It is natural and normal for language to change；the only languages which do not change are the dead ones．This is easy to understand if we look backward in time．Change goes on in all aspects of language．Grammatical features change as do speech sounds．and changes in vocabulary are sometimes very extensive．and may occur Very rapidly．Vocabulary is the least stable part of any languages.
In the second paragraph the author thinks that__________.
A．some backward race doesn’t have a language of its own
B．some race in history didn’t possess a language of its own
C．any human race，whether backward or not，has a language
D．some races on earth can communicate without language


2、根据以下内容回答题：
No one knows for sure why birds migrate．One theory of migration says that ancient birds of the northern part of the earth were forced southward during the Ice Age，when ice covered large parts of Europe，Asia and North America．As the ice melted，the birds came back to their homelands，spent the summer，and then went south again in winter．Gradually，these comings and goings became habits，and birds now migrate though much of the ice has gone．
Another theory proposes that the ancient home of all modern birds was the tropic areas．There lived so well that the region became overcrowded．Many species had to move northward．During the summer，these birds found plenty of room and food．In winter，however，food be-came scarce and they had to return to the south．
A newer theory is that increasing daylight stimulates certain glands(腺)in the bird’s body and prepares it for migration．One scientist is able to make birds migrate in midwinter by expo-sing them for two months to artificial daylight．Recoveries of marked birds indicate that they fly north as soon as they are set free．The conclusion is that the urge to migrate is determined by changes in the bird’s body which take place under seasonal changes in the length of daylight．
This theory would account for the fact that not all birds migrate at the same time．Each sDecies seems to have its own schedule．The theory would also account for the regular time and rou‘tes of migration．Birds arrive at a given place year after year．Unfavorable weather delays them only a few days．Total hours of daylight，rather than weather，start them on the way．
How birds find their way to the same place year after year and why they follow their own Darticular route are still mysteries．They evidently do not follow known landmarks，for many young birds migrate alone without the help of experienced adults．
We can conclude from the first paragraph that__________ ．
A．during the Ice Age，the whole Europe was covered with ice
B．the south used to be the homelands of all birds
C．scientists can confidently explain why birds migrate now
D．migration of birds can be explained by the change of ice on earth

7、根据下面材料，回答题：
Concerning money or anything else, conflicts between husband and wife usually reflect a powerstruggle. Conflicts between parent and child often center around the same issue. As children enter ad-olescence, they begin to demand greater freedom to go where they please, do what they please, andmake decisions without parental interference. Many American parents do not know how to deal withtheir teenagers and seek advice from books, lectures, and parent-training courses. Parents want to maintain a friendly relationship with their teenagers and also want to guide them so that their behaviorwill be whatever the parents consider proper and constructive.
But in a society of rapidly changing social and moral values, parents and children often disagree about what is important and what is right.
Arguments may concern such unimportant matters as styles of dress or hairdos. But quarrels mayalso concern school work, after school jobs, decisions, use of the family car, dating, and sex behav-ior. Some famihes have serious problems with teenagers who drop out of school, run away from home,or use illegal drugs. Because so much publicity is given to the problem teenager, one gets the impres-sion that all teenagers are troublemakers. Actually, relatively few adolescents do anything wrong, andnearly all grow up into "solid citizens" who fulfill most of their parents' expectations. In fact, recentstudies show that the "generation gap" is narrowing. The vast majority of teenagers share most of theirparents' values and ideas. Many parents feel that they get along with their adolescents quite well.
