Question

Scientific experiments can sometimes go wrong and when they do the results may range from the disastrous to the troubling. One such experiment took place in South America about fifty years ago. Whether its final consequences will cause serious damage or nothing more than a small trouble still remains to be seen.
The story began in 1956 when an American scientist working in Brazil decided to solve the problem of increasing the productivity of that country’s bees. He imported a very active type of African bee from Tanzania and mated (交配)it with the more easy-going native variety to produce a new kind of bees. The new bees worked harder and produced twice as much honey. It seemed that Professor Kerr, for that was the scientist's name, had a total success on his hands.
Then things began to go wrong. For some reason as yet unseen, but perhaps as a result of something in their environment, the new bees began to develop extremely attacking personalities. They became bad-tempered and easy to be angry, attacked the native bees and drove them from their living places.
But worse was to follow. Having taken over the countryside, the new bees, with their dangerous stings (叮) , began to attack its neighbors -- cats, dogs, horses, chickens and finally man himself. A long period of terror began that has so far killed a great number of animals and about 150 human beings.
This would have been bad enough if the bees had stayed in Brazil. But now they are on the move, heading northwards in countless millions towards Central and North America, and moving at the alarming speed of 200 miles a year. The countries that lie in their path are naturally worried because it looks as if nothing can be done to stop them.

B．make Brazilian bees more easy-going

C．increase the number of bees in Brazil

D．increase the amount of honey in Brazil

小題3: Which of the following may be the cause of the new bees' attacking personalities?

Answer 1

小題1:A
小題2:D
小題3:B
小題4:C

試題解析：本文通過一個(gè)實(shí)例：引進(jìn)新的蜜蜂以增加蜂產(chǎn)品的同時(shí)帶來(lái)的不僅是給巴西還有其他的國(guó)家?guī)��?lái)困擾來(lái)說(shuō)明：科學(xué)實(shí)驗(yàn)有時(shí)會(huì)不科學(xué)。
小題1:細(xì)節(jié)理解題.根據(jù)第一段最后一句話Whether its final consequences will cause serious damage or nothing more than a small trouble still remains to be seen.最終的結(jié)果是將導(dǎo)致嚴(yán)重的損害還是僅僅是一個(gè)小問題還有待于研究，所以Ａ正確
小題2:細(xì)節(jié)理解題。根據(jù)第二段第一句話  The story began in 1956 when an American scientist working in Brazil decided to solve the problem of increasing the productivity of that country’s bees.由此可以判斷出Ｄ正確。
小題3:細(xì)節(jié)理解題。根據(jù)第四段開頭  But worse was to follow. Having taken over the countryside, the new bees, with their dangerous stings (叮) , began to attack its neighbors -- cats, dogs, horses, chickens and finally man himself.可以判斷出是環(huán)境變了，導(dǎo)致了這些問題，所以Ｂ正確。
小題4:推理判斷題。根據(jù)最后一段第一句話This would have been bad enough if the bees had stayed in Brazil. But now they are on the move, heading northwards in countless millions towards Central and North America, and moving at the alarming speed of 200 miles a year.可以推斷出這些蜜蜂會(huì)給更多的國(guó)家?guī)��?lái)困擾，所以Ｃ正確。
