【题目】Scientists in Britain have managed to teach bumblebees(大黄蜂) to pull strings to get to food and then pass on what they have learned to others in their colony(群体)showing a high level of intelligence despite their tiny brains.

Researchers at Queen Mary University of London said the experiments, often used to test the intelligence of apes (猿) and birds, showed for the first time that some insects are up to the task, and can also pass skills on through several generations.

The findings add to the evidence suggesting the ability for “culture spread” the ability to learn and pass on knowledge and skills — may not be exclusive to humans.

In the research, published in the journal PLOS Biology on Tuesday, the scientists were able to train 23 out of a group of 40 bees to pull strings with their legs and feet.

The strings were attached to discs — or artificial “flowers” — containing food at their center but placed under a transparent screen. The bees, spotting the food beneath the screen, learned to pull the “flowers” out by pulling the string with their legs and feet to be able to get to it.

From another group of bees given the chance to solve the task without any training, only two of 110 were successful.

Another group of bees was then allowed to observe the trained bees pulling the strings, and 60 percent of them successfully learned the skill. Finally, trained bees were put in colonies, and the scientists found the technique spread successfully to a majority of the colony’s worker bees.

Lars Chittka, a Queen Mary University professor who guided the project, said the team is interested in figuring out the brain processes behind the bees’ learning and teaching skills.

1What does the underlined word “exclusive” in Paragraph 3 probably mean?

A. Ordinary. B. Unique. C. Beneficial. D. Widespread.

2What did the researchers find about bees?

A. Bees learn best in insects.

B. Bees are as clever as birds.

C. Bees are born good learners.

D. Bees can be trained to learn skills.

3What may the research team focus on next?

A. What else bees can do. B. Where bees learn skills.

C. How bees teach others. D. How bees’ brain work.

4What may be the best title for the text?

A. Small bees, great abilities B. Bees can learn and teach

C. Bees are smarter D. Let bees learn

【解析】本文为说明文,属于科普类文章。介绍了大黄蜂有学习能力,还会传播自己学到的知识。

1猜测词义题。依据第二段可知,大黄蜂也具有学习并传播所学知识的能力,结合第三段本句话可知,这种能力并非人类独有的,故选B项。

2细节理解题。根据第三、四、五、六、七段可知,蜜蜂可以被训练学习技能。D项正确。

3推理判断题。根据文章最后一句...the team is interested in figuring out the brain processes behind the bees’ learning and teaching skills.可知,该小组感兴趣的是找出蜜蜂学习和教学技能背后的大脑活动过程。故D项正确。

4主旨大意题。综合全文尤其第一段可知,文章主要介绍一项科学发现,大黄蜂也可以学习并传播所学技能,故选B项。
