Question

（2014安徽）

  North American black bears are shy animals．They are fearful by nature，and will usually run away if they see or hear people．Because of this，it can be difficult for scientists to learn about these animals．

  In order to study black bears，researchers from New Jersey，the USA，catch bears and use drugs to help them go to sleep．Researchers then work out the size and the weight of the bear，take blood to test for diseases，remove a tooth and take it to the lab to find out its age．From these studies，researchers want to find out how many bears live in New Jersey，how long they live，and how many babies they produce．

  But in Minnesota，the USA，researchers study bears that are completely awake．The bears know the researchers’voices and they are not afraid of the research team．With the help of a few grapes to keep the bears busy，researchers can touch them to check their hearts，look at their teeth，and do other jobs．Researchers can also walk or sit with bears for hours and make videos to learn about their everyday lives．

  In both places．the main purpose is the same—to make sure there is a healthy population of black bears．But the research methods and the kinds of information that researchers are able to collect are quite different．

4.D

5.B

【解析】

1.North American black bears are shy animals．They are fearful by nature…可知，北美黑熊天生害羞、胆小，故选A项。

2.take it to the lab to find out its age可推断，必须拔下（remove）黑熊的牙齿才能将它拿到实验室去研究，故选A项。

3.Researchers then work out the size and the weight of the bear…和第二段最后一句…and how many babies they produce．可知，在新泽西州的研究包括弄清黑熊的年龄、体重、健康状况、数量、寿命和产崽数量，而它们的沟通方式不包括在内，故选B项。

4.Researchers can also walk or sit with bears for hours and make videos to learn about their everyday lives．可知，研究人员可以了解很多关于黑熊的日常生活，故选D项。

5.In both places，the main purpose is the same—to make sure there is a healthy population of black bears．可知，两项研究的主要目的是一致的，故选B项。
