Betty, a New Caledonian crow living in a research lab, was hungry. She could see a piece of meat at the bottom of a glass test tube, but she could not reach it. In the wild, crows use twigs to dig into trees to get insects. There were no twigs in Betty’s cage, but that didn’t stop the hungry crow. She found a straight piece of wire that someone had left in the cage. She picked it up with her beak. Then she stuck the wire under some sticky tape that was also in her cage, and bent the wire. Finally, she used her new tool to remove the piece of meat from the test tube. The scientists in the lab watched in amazement as she popped the piece of meat in her mouth. They knew crows could use tools, but could they make them? That was something new. Clearly crows were more intelligent than they had thought.

In another show of intelligence, a group of crows in a Tokyo suburb have learned a new way to get lunch. They fly over intersections and drop nuts in front of cars. The cars drive over the nuts, and the crows wait for the light to change. When the light turns red, the cautious crows fly down and eat the nuts without fear of being run over. The behavior has become widespread as more and more crows teach it to others. After observing crow behavior in the laboratory and in the wild, scientists now believe that the birds are not just acting instinctively. They believe that crows have the intellectual capacity to plan, solve problems, and teach new behaviors to others.

These stories of crow genius attracted the attention of a writer named Joshua Klein. To find out if crows could be trained, Klein designed an experiment. He built a vending machine for crows. Inside the machine were nuts. He knew that crows were attracted to shiny things, so he put coins on the ground around the machine. At first, the crows just picked up the coins. By chance, a few crows dropped some coins into the machine and were rewarded with a nut. Soon the crows appeared to understand the relationship among the coins, the machine, and the nuts. Klein’s experiment, along with other research, shows how well crows can adapt to new challenges.

1. How did Betty get the meat from the test tube?

A. By using the wire. B. By digging.

C. By using her beak. D. By popping.

1.【答案】A

【解析】细节理解题。根据第一段第七、八句“Then she stuck the wire under some sticky tape that was also in her cage, and bent the wire. Finally, she used her new tool to remove the piece of meat from the test tube.”可知，乌鸦是用铁丝取出了那块肉。故选A。

B. The traffic is very busy in the Tokyo suburb.

C. The crows can learn behaviors from each other.

D. The drivers run over the nuts to help the crows.

2.【答案】C

【解析】细节理解题。根据第二段第五句“The behavior has become widespread as more and more crows teach it to others.”以及本段最后一句“They believe that crows have the intellectual capacity to plan, solve problems, and teach new behaviors to others”可知，乌鸦可以互相学习。故选C。

D. To test whether crows could be attracted to shiny things.

3.【答案】C

【解析】细节理解题。根据第三段第二句“To find out if crows could be trained, Klein designed an experiment.”可知，Klein设计这一实验的目的是弄清楚乌鸦是否可以被训练。本句中的be trained和C项中的be taught属于同义替换。故选C。

4. What impressed the scientists most according to the text?

A. The crows’ way of acting instinctively.

B. The crows’ ability to learn and think.

C. The crows’ behavior of dropping nuts.

D. The crows’ understanding of the experiments.

4.【答案】B

【解析】推理判断题。本文主要通过几个实验证明乌鸦比人们想象得更聪明，它们有规划、解决问题和教给其它同类新行为的智力。因此最让科学家留下最深印象的应该是乌鸦的学习和思考能力。故选B。
