英语(专科起点本科)3A

一、阅读理解(共20题,共40分)

1.Despite the fact that today viruses(病毒)are known to cause cancer in animals and in certain plants, there exists a great reluctance to accept viruses as being of importance in human cancer.Basic biological phenomena generally do not differ strikingly as one goes from one species to another.It should be recognized that cancer is a biological problem and not a problem that is unique to man.Cancer originates when a normal cell suddenly becomes a cancer cell which multiplies widely and without apparent restraint.Cancer may originate in many different kinds of cell, but the cancer cell usually continues to carry certain traits(特性)of the cell of origin.The transformation of a normal cell into a cancer cell may have more than one kind of cause, but there is good reason to consider the relationships that exist between viruses and cancer.Since there is no evidence that human cancer, as generally experienced, is infectious, many persons believe that because viruses are infectious agents they cannot poibly be of importance in human cancer.However, viruses can mutate(突变)and examples are known in which a virus that never kills its host can mutate to form a new strain of virus that always kills its host.It does not seem unreasonable to aume that a harmle latent virus might mutate to form a strain that causes cancer.Certainly the experimental evidence now available is consistent with the idea that viruses as we know them today could be the causative(引起…的)agents of most, if not all cancer, including cancer in man.(10分)

(1)According to the paage, cancer cells are ____.(2分)A.similar to the cell of origin B.mutations of viruses C.unable to reproduce

D.among the smallest cell known

标准答案:A

(2)The best title for this paage is ____.(2分)A.New Light on the Causes of Cancer B.The Newest Theory on the Nature of Viruses C.Viruses and cancer D.On the Nature of Life

标准答案:C

(3)Cancer should be considered to be a biological problem rather than a medical one because ____.(2分)A.viruses are known to cause cancer in animals

B.at present, human cancer is not believed to be infectious

C.there are many known causes for the transformation of a normal cell to a cancer cell D.results of experiments on plants and animals do not vary greatly from species to species

标准答案:D(4)Many people believe that viruses cannot poibly be of importance in human cancer because ____.(2分)A.they are harmle agencies

B.they are the causative agents of most human cancer C.they seem to be infectious to many people

D.they are generally thought to be relevant to most cancer in man

标准答案:C

(5)The poibility that a virus causes human cancer is indicated by ____.(2分)A.the fact that viruses have been known to mutate

B.the fact that a cancer-immune(免疫的)individual may lose his immunity C.the fact that production of human cancer cells might be due to a genetic factor D.the fact that man is host to many viruses

标准答案:A

2.We all know that it is poible for ordinary people to make their homes on the equator, although often they may feel uncomfortably hot there.Millions do it, but as for the North Pole---we know that it is not only a dangerously cold place, but that people like you and me would find it quite impoible to live there.At the present time only the scientists and explorers can do so, and they use special equipment.Men have been traveling acro and around the equator on wheels, on their feet or in ships for thousands of years;but only a few men, with great difficulty and in very recent time, have ever croed the ice to the North Pole.So it may surprise you to learn that, when traveling by air, it is really safer to fly over the North Pole than over the equator.Of course, this is not true about landings in the polar region(which paenger aeroplanes do not make), but the weather, if we are flying at a height of 5,000 meters above the Pole, is a delight.At 4,000 meters and more above the earth you can always be sure that you will not see a cloud in the sky as far as the eye can reach.In the tropics, on the other hand, you are not certain to keep clear of bad weather, even at such heights as 18,000 or 20,000 meters.Aeroplanes can’t climb as high or as quickly in cold air as in warm.Nor can clouds.In practice, this is an advantage to the aeroplane, which is already at a good height when it reaches the polar region and so does not need to climb, while at the same time cold air keeps the clouds down low.(10分)

(1)The polar region is ____.(2分)A.a good place to land at by aeroplane B.a good place to fly over C.a good place to live in D.a good place to cro

标准答案:B

(2)It is a delight to fly at the Pole because there ____.(2分)A.planes fly higher than at the equator B.the eyes can reach about 4,000 meters C.planes fly more quickly than at the equator D.planes are clear of bad weather

标准答案:D

(3)Aeroplanes usually do not need to climb quickly or fly high in the polar region because ____.(2分)A.they do not land there B.there are no clouds at all

C.they can cro the ice with special equipment D.it is very cold

标准答案:D

(4)In the sentence “Millions do it”, “do it” refers to ____.(2分)A.feeling uncomfortably hot on the equator B.flying over the North Pole C.flying over the equator D.making homes on the equator

标准答案:D

(5)Aeroplanes can climb quickly ____.(2分)A.in warm air B.in cold air

C.when it reaches the polar region D.only when the clouds are down low

标准答案:A

3.Our environment is getting worse and worse with the increase of the world population,which affects the environment in two ways.Firstly, the limited energy resources will be used up much faster.Secondly, the increasing population creates more pollution,another severe problem that needs to be solved.Both problems are long-term ones because actions taken now show their results slowly over many years.They are also urgent because delays in action can lead to great suffering and social problems.The question seems to be difficult to handle for most people.However, a person can be a protector of environment in everyday life if he takes actions to save the environment right now.With the development of technology, cars make transportation easier and quicker than before, but we can’t ignore the disadvantages brought to us by more and more cars in use.For example, we are consuming gasoline(汽油), which is a non-renewable(无法更新的)resource, and will soon be gone.Moreover, the exhausted gas from cars pollutes our air, and our health is therefore threatened by air pollution, which has a big potential effect on our daily life.So we can consider walking, taking buses, carpooling(合用汽车), instead of driving cars alone.This seems to be a very slow proce that can’t be so effective if it’s taken by a single person.But when more and more people become aware of the importance and positively take it as their personal responsibilities.The condition of the air will be improved to a great extent.(10分)

(1)The author’s main purpose in writing this paage is most probably to ____.(2分)A.complain about people's slow actions to protect the environmentB.advise people to take actions to protect the environmentC.show himself to be an active environment protector

D.point out the bad effects of technologies in protecting environment

标准答案:B

(2)From the paage, we can know that ____.(2分)

A.effective measures can be taken mainly by the government B.taking measures now can soon improve the environment

C.immediate measures can cause great suffering and social problems D.every single person’s action has some effect on environment protection

标准答案:D

(3)According to the writer, the main problem to our environment today is ____.(2分)A.the increase of population B.the limited energy resources C.the more serious air pollution D.the development of technology

标准答案:A

(4)The paage is mainly about ____.(2分)

A.energy resources savingB.environment protectionC.population controlD.air pollution

标准答案:B

(5)The author believes that carpooling ____.(2分)A.can give help to those without cars B.can save people money and time

C.can save energy resources and reduce air pollution D.can promote friendship among drivers

标准答案:C

4.The elephant is the biggest four-legged animal in the world.It is also, perhaps, the gentlest;but not always!

Elephants are like us in some ways.They live for a long time---fifty or sixty years.They can remember things very well.They never forget great sadne or great happine.When a female elephants dies, her daughters and

grandmothers are sad for many months.They stay with the dead body.Then they carry a bit of it away with them.They never forget a dead friend.Elephants are like us, but they are also different.They live in families, families of females.There will be a few young males---a few “baby boys”.But the females will soon send them away.An elephant family keeps only its daughters, mothers, grandmothers and its great-grandmothers.The females stay together for fifty, sixty … a hundred years.The older animals look after the younger ones.The mothers teach their daughters and set a good example.And what happens to male elephants? Well, the young males stay with their mothers for a time.Then they must leave family.The females just send them away.A bull(雄的)elephant does not often have a friend.He lives apart away from the family, and often away from other bulls.Sometimes the females call a bull.He can visit them then, and stay for a time.But soon his “wives” and sisters send him away again.The females have very happy family life.What does the bull think about it? We don’t know.(10分)

(1)What happens to a male elephant when it grows up?(2分)A.He often lives together with his wife.B.He leaves the family.C.He tries to form a new family.D.He lives with other male friends.标准答案:B
