Question

【题目】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, 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(疾病), 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, USA, researchers study bears that are completely awake. The bears know the researchers' voices and they are not afraid of die 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.

【1】 In the first paragraph, we can learn that North American black bears are _______.

A. shy and fearful animals B. not found today

C. well known to scientists D. not afraid of people

【2】 The word "remove" in the second paragraph probably means _____ in Chinese.

A. 拔下 B.移植 C. 清洗 D. 修补

【3】Which of the following may NOT be included in the New Jersey studies on bears?

A. The age. B. The way of their communication.

C. The weight. D. The number of babies they produce.

【4】In the Minnesota studies, researchers _____.

A. can never get close to the bears

B. study the bears while they are asleep

C. use grapes to make the bears full

D. learn a lot about the bears' everyday lives

【5】What do the two studies have in common?

A. Research places. B. The main purpose.

C. Research methods. D. Collected information.

【解析】

试题分析：本文介绍了在明尼苏达州和新泽西州人们研究黑熊及获取信息的不同方法。

【1】A 细节理解题。题意：在第一自然段中，我们了解到北美洲黑熊：A.是胆小害羞的动物；B.是如今未被发现的动物；C.是被科学家所熟知的动物；D.是不怕人的动物。根据短文内容，北美洲黑熊胆小害羞。故选A。

【2】A 词义猜测题。题意：第二自然段中的remove可能的汉语意思是什么？ A.拔下；B.移植； C.清洗；D. 修补。根据原文，研究者测出熊的大小、重量、抽血查疾病，把一颗牙齿取下拿到实验室去测熊的年龄。应该是拔下一颗牙齿，因此选A。

【3】B 细节理解题。题意：下面哪一个不被包括在新泽西对熊的研究中？A.年龄；B.交流方式；C.体重；D.生产小熊的数量。根据原文，新泽西的研究者们，用熊的牙齿测其年龄，用药后测量其大小和重量，通过各种方式算出小熊的数量。因此，正确答案是B。

【4】D 细节理解题。题意：在明尼苏达州的研究中，研究者：A.从不靠近熊；B.在熊睡着时研究熊；C.用葡萄让熊吃饱；D.了解了许多有关熊的日常生活。根据短文内容，明尼苏达州的研究者们，用葡萄靠近熊，同熊一起步行，了解许多有关熊的日常生活。因此，选D。

【5】B 细节理解题。题意：两个研究的共同处是什么？A.研究的地点；B.研究的目的；C.研究的方法；D.收集的信息。原文最后一自然段说，两个研究的目的都是“确保有一个健康的熊的数量”，因此，选B。
