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】細(xì)節(jié)理解題。根據(jù)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，烏鴉是用鐵絲取出了那塊肉。故選A。

2. What can we learn from Paragraph 2?

A. The crows fly away when the lights turn red.

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】細(xì)節(jié)理解題。根據(jù)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，烏鴉可以互相學(xué)習(xí)。故選C。

3. Why did Joshua Klein design the experiment?

A. To prove that crows could pick up the coins.

B. To try to build a vending machine for crows.

C. To find out if crows could be taught some skills.

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

3.【答案】C

【解析】細(xì)節(jié)理解題。根據(jù)第三段第二句“To find out if crows could be trained, Klein designed an experiment.”可知，Klein設(shè)計(jì)這一實(shí)驗(yàn)的目的是弄清楚烏鴉是否可以被訓(xùn)練。本句中的be trained和C項(xiàng)中的be taught屬于同義替換。故選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】推理判斷題。本文主要通過幾個(gè)實(shí)驗(yàn)證明烏鴉比人們想象得更聰明，它們有規(guī)劃、解決問題和教給其它同類新行為的智力。因此最讓科學(xué)家留下最深印象的應(yīng)該是烏鴉的學(xué)習(xí)和思考能力。故選B。
