12.【2018年陕西省中考】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 (水平线) 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 (垂直线), 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.

【答案】26. D    27. A    28. C
【解析】本文介绍了几种比较聪明的动物：海豚，蜜蜂和大猩猩。
26. 句意：在测试中，海豚试图清除身体上的红色标记。A.感到害怕并逃离镜子B.试着和镜子里的自己打架C.他们的身上没有发现任何红色标记D.试图清除身体上的红色标记。原文“they tried to clean the red marks off their bodies.”（它们试图清除身体上的红色标记），这里描述的是海豚看到镜子里的自己后采取的行动，故选D。
27. 句意：当蜜蜂看到垂直线时，它们飞走了。A.飞走了B.找到了更高的线C.呆在那里D.找到了数字。原文“when the researchers showed them vertical lines, the bees simply flew away”（当研究人员向他们展示垂直线时，蜜蜂只是飞走了），故选A。
28. 句意：年轻的黑猩猩在记住数字的位置时表现得更好。A.成年黑猩猩B.老年黑猩猩C.年轻的黑猩猩D.大学生。原文“but the young chimpanzees performed much better.”（但年轻的黑猩猩表现得更好。），故选C。
