Question

【題目】

When we talk about snails, it is easy to think of their slow move. But much of the time snails don’t move at all. They are in their shells-- sleeping. In the spring the snail wakes up. Its body, about three inches long, comes out from the shell. When hungry, the snail looks for food. Its eyes, at the end of the top feelers (觸角), are very weak. But its sense of smell is very strong. It helps the snail to find food and the new greens.

Scientists have always believed that snails are not able to find their way home. But Briton Ruth Brooks, a retired (退休的)teacher, has found that it is not true.

Brooks began an experiment on snails after she got mad with the snails in her garden. The snails had eaten her vegetables. She didn’t want to kill them, so she took them to another place. But she found they always seemed to come back.

Brooks did an experiment. She marked the snails in her garden with nail polish (指甲油). She placed the snails in the area around her home and made notes of their movements. She found that snails have a strong homing instinct(本能); the longest returning snail traveled back 90 meters.

Brooks has been named Britain’s best amateur (業(yè)余的)scientist after her work won the BBC Radio 4 project, So You Want To Be A Scientist. She said, “I’ve always wanted to know whether the snails that eat my plants just come back when I move them, and if they do, what is their homing distance? “I would say on the evidence (證據(jù)) that it would be safe to take your snails away beyond 100 meters or even further. If you put them somewhere nice with some food, you can be almost certain that they won’t come back.”

【3】What might Brooks’ advice be for keeping snails away?

A.You’d better kill them.

C.Move them to a nice place with food.

【4】According to the passage, we know that ________.

Answer 1

【答案】

【1】B

【2】B

【3】C

【4】C

【5】A

【解析】

這篇短文是關(guān)于蝸牛的。蝸牛大部分的時間都在睡覺，不管是晴天還是雨天，它都縮在殼里睡覺，冬天還會冬眠，春天它就醒了，用它的嗅覺來尋找食物。蝸牛有很多牙齒，可以用來吃東西，而且牙齒會更換，它一般晚上尋找食物。

【1】細(xì)節(jié)理解題。根據(jù)“But Briton Ruth Brooks, a retired (退休的)teacher”可知，布魯克斯是一個退休教師，故選B。

【2】推理判斷題。根據(jù)“But she found they always seemed to come back.”她發(fā)現(xiàn)這些蝸牛好像總能回來，及“Brooks did an experiment. She marked the snails in her garden with nail polish”為此她做了一個實驗，給這些蝸牛用指甲油做了標(biāo)記，由此可以推測，做標(biāo)記是為了看看他們是否能回來。故選B。

【3】細(xì)節(jié)判斷題。根據(jù)“If you put them somewhere nice with some food, you can be almost certain that they won’t come back.” 如果你把它們放在有食物的好地方，幾乎可以肯定它們不會再回來了，可知布魯克斯讓蝸牛遠(yuǎn)離的建議可能是把他們放在有食物的好地方，故選C。

【4】推理判斷題。根據(jù)“the longest returning snail traveled back 90 meters.” 最長的蝸牛返回距離是90米，及“it would be safe to take your snails away beyond 100 meters or even further” 把你的蝸牛移到100米以外甚至更遠(yuǎn)的地方是安全的，可推測蝸牛在一定的距離內(nèi)可以找到家，故選C。

【5】文章出處題。全文的介紹是關(guān)于蝸牛，B是科幻小說，C是故事書，均不符合，用排除法，該文章最可能出現(xiàn)在報紙上。故選A。
