Question

【題目】根據(jù)短文理解，選擇正確答案。
It's a popular belief that a fish's memory lasts for only seven seconds. It may seem sad to think that they don't remember what they've eaten or where they've been, and they don't recognize you or any of their friends — every moment in their life would be like seeing the world for the first time.
But don't be so quick to feel sorry for them. A new study has found that fish have a much better memory than we used to think. In fact, certain species of fish can even remember events from as long as 12 days ago.
In the study, researchers from MacEwan University in Canada trained a kind of fish called African cichlids to go to a certain area of their tank to get food. They then waited for 12 days before putting them back in the tank again.
Researchers used computer software to monitor the fish's movements. They found that after such a long break the fish still went to the same place where they first got food. This suggested that they could remember their past experiences.
In fact, scientists had been thinking for a long time that African cichlids might have a good memory. An earlier study showed that they behaved aggressively（挑釁地） in front of certain fish, perhaps because they remembered their past “fights”. But until the latest findings, there was no clear evidence.
Just as a good memory can make our lives easier, it also plays an important part when a fish is trying to survive in the wild.
“If fish are able to remember that a certain area contains safe food, they will be able to go back to that area without putting their lives at risks,” lead researcher Trevor Hamilton told Live Science.
For a long time, fish were placed far below chimpanzees, dolphins and mice on the list of smart animals. But this study has given scientists a new understanding of their intelligence.

（4）B
【解析】人們普遍認為魚的記憶力只有七秒。 本文講述了一項新的研究發(fā)現(xiàn)，魚的記憶力比我們過去認為的要好得多，某些種類的魚甚至可以記住12天前的事件。

⑴主旨大意。根據(jù)第二段第二句A new study has found that fish have a much better memory than we used to think.（一項新的研究發(fā)現(xiàn)，魚的記憶力比我們過去認為的要好得多）；根據(jù)文章最后一段But this study has given scientists a new understanding of their intelligence.（但是這項研究使科學家們對他們的智力有了新的認識。）可知“魚比我們認為的聰明”是文章的大意。故選B

⑵細節(jié)理解。根據(jù)第一段中they don't recognize you or any of their friends可知，他們不認識你或他們的任何一個朋友。故選D。

⑶細節(jié)理解。根據(jù)第四段最后They found that after such a long break the fish still went to the same place where they first got food. This suggested that they could remember their past experiences. （他們發(fā)現(xiàn)，休息這么長時間的魚還能回到第一次得到食物的地方。這表明他們可以記住他們過去的經(jīng)歷。）可知，他們知道在哪里能得到食物和生存。故選A。

⑷推理判斷。根據(jù)第五段最后一句But until the latest findings, there was no clear evidence.（至今沒有清晰的證據(jù)。）故排除A；根據(jù)最后一段For a long time, But this study has given scientists a new understanding of their intelligence. （很長時間，魚被放置在遠遠低于黑猩猩，海豚和老鼠的名單上，但是這項研究使科學家們對他們的智力有了新的認識。）故排除C；根據(jù)第五段第一句African cichlids might have a good memory. （African cichlids可能有一個好的記憶，但并未說只有African cichlids才有好的記憶。）only太絕對，故排除D�？v觀全文，又根據(jù)第二段第二句A new study has found that fish have a much better memory than we used to think.選故B
