Question

【題目】Many animals around us are smart. Let’s get to know some of them.

Dolphins are smarter animals in the sea. Researchers put sea animals to a test. In the test, the researchers made red marks on the animal’s bodies and took them in front of a mirror. Many sea animals either ran away or fought with the ones in the mirror. However, when the dolphins saw themselves in the mirror, they tried to clean the red marks off their bodies. So the researchers believed that the dolphins knew the ones in the mirror were just themselves.

Bees work hard, and they are smart enough to learn something. Researchers found a group of bees and taught them to tell which horizontal line (水平線) was higher than the other. If they could find the higher line, they would get sugar as a prize. After training for a period of time, the researchers tested the bees. To their surprise, the bees found the higher horizontal line quickly and got sugar. Instead, when the researchers showed them vertical lines (垂直線), the bees simply flew away, because they knew there was no way to get sugar.

Chimpanzees (黑猩猩) are very human-like. They can learn fast and well. Researchers showed the numbers from one to nine on the screen. Chimpanzees and some college students were asked to remember where the numbers were after watching the numbers in less than a second. The adult chimpanzees and the college students performed almost the same, but the young chimpanzees performed much better. It was amazing.

【1】In the test, the dolphins _______________.

A. felt afraid and ran away from the mirror

B. tried to fight with the ones in the mirror

C. didn’t find any red marks on their bodies

D. tried to clean the red marks off their bodies

【2】When the bees saw the vertical lines, they _________.

A. flew away

B. found the higher line

C. stayed there

D. found the numbers

【3】_____________ performed better in remembering where the numbers were.

A. The adult chimpanzees

B. The old chimpanzees

D. The college students

Answer 1

【答案】

【1】D

【2】A

【3】C

【解析】本文介紹了幾種比較聰明的動物：海豚，蜜蜂和大猩猩。

【1】句意：在測試中，海豚試圖清除身體上的紅色標(biāo)記。A.感到害怕并逃離鏡子B.試著和鏡子里的自己打架C.他們的身上沒有發(fā)現(xiàn)任何紅色標(biāo)記D.試圖清除身體上的紅色標(biāo)記。原文“they tried to clean the red marks off their bodies.”（它們試圖清除身體上的紅色標(biāo)記），這里描述的是海豚看到鏡子里的自己后采取的行動，故選D。

【2】句意：當(dāng)蜜蜂看到垂直線時，它們飛走了。A.飛走了B.找到了更高的線C.呆在那里D.找到了數(shù)字。原文“when the researchers showed them vertical lines, the bees simply flew away”（當(dāng)研究人員向他們展示垂直線時，蜜蜂只是飛走了），故選A。

【3】句意：年輕的黑猩猩在記住數(shù)字的位置時表現(xiàn)得更好。A.成年黑猩猩B.老年黑猩猩C.年輕的黑猩猩D.大學(xué)生。原文“but the young chimpanzees performed much better.”（但年輕的黑猩猩表現(xiàn)得更好。），故選C。
