Question

【題目】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/span> 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. 修補(bǔ)

【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】

試題分析：本文介紹了在明尼蘇達(dá)州和新澤西州人們研究黑熊及獲取信息的不同方法。

【1】A 細(xì)節(jié)理解題。題意：在第一自然段中，我們了解到北美洲黑熊：A.是膽小害羞的動(dòng)物；B.是如今未被發(fā)現(xiàn)的動(dòng)物；C.是被科學(xué)家所熟知的動(dòng)物；D.是不怕人的動(dòng)物。根據(jù)短文內(nèi)容，北美洲黑熊膽小害羞。故選A。

【2】A 詞義猜測(cè)題。題意：第二自然段中的remove可能的漢語(yǔ)意思是什么？ A.拔下；B.移植； C.清洗；D. 修補(bǔ)。根據(jù)原文，研究者測(cè)出熊的大小、重量、抽血查疾病，把一顆牙齒取下拿到實(shí)驗(yàn)室去測(cè)熊的年齡。應(yīng)該是拔下一顆牙齒，因此選A。

【3】B 細(xì)節(jié)理解題。題意：下面哪一個(gè)不被包括在新澤西對(duì)熊的研究中？A.年齡；B.交流方式；C.體重；D.生產(chǎn)小熊的數(shù)量。根據(jù)原文，新澤西的研究者們，用熊的牙齒測(cè)其年齡，用藥后測(cè)量其大小和重量，通過(guò)各種方式算出小熊的數(shù)量。因此，正確答案是B。

【4】D 細(xì)節(jié)理解題。題意：在明尼蘇達(dá)州的研究中，研究者：A.從不靠近熊；B.在熊睡著時(shí)研究熊；C.用葡萄讓熊吃飽；D.了解了許多有關(guān)熊的日常生活。根據(jù)短文內(nèi)容，明尼蘇達(dá)州的研究者們，用葡萄靠近熊，同熊一起步行，了解許多有關(guān)熊的日常生活。因此，選D。

【5】B 細(xì)節(jié)理解題。題意：兩個(gè)研究的共同處是什么？A.研究的地點(diǎn)；B.研究的目的；C.研究的方法；D.收集的信息。原文最后一自然段說(shuō)，兩個(gè)研究的目的都是“確保有一個(gè)健康的熊的數(shù)量”，因此，選B。
