For those who study the development of intelligence (智力) in the animal world，self-awareness is an important measurement. An animal that is aware (意识) of itself has a high level of intelligence.

Awareness can be tested by studying whether the animal recognizes itself in the mirror, that is，its own reflected image (反射出的影像). Many animals fail this exercise bitterly, paying very little attention to the reflected image. Only humans, and some intelligent animals like apes and dolphins，have been shown to recognize that the image in the mirror is of themselves.

Now another animal has joined the club. In the Proceedings of the National Academy of Sciences, researchers report that an Asian elephant has passed the mirror self-reflection test.

“We thought that elephants were the next important animal.” said Diana Reiss of the Wildlife Conservation Society, an author of the study with Joshua M. Plotnik and Fans B. M. de Waal of Emory University. With their large brains, Reiss said, elephants “seemed like cousins to apes and dolphins”.

The researchers tested Happy, Maxine and Patty, three elephants at the Bronx Zoo. They put an 8-foot-square mirror on a wall of the animals’ play area (out of the sight of zoo visitors) and recorded what happened with cameras, including one built in the mirror.

The elephants used their long noses to find what was behind it, and to examine parts of their bodies.

Of the three, Happy then passed the test, in which a clear mark was painted on one side of her face. She could tell the mark was there by looking in the mirror, and she used the mirror to touch the mark with her long nose.

Diana Reiss said, “We knew elephants were intelligent, but now we can talk about their intelligence in a better way.”

1.What can mirror tests tell us about animals?

A.Whether they have large brains.

B.Whether they have self-awareness.

C.Whether they enjoy outdoor exercises.

D.Whether they enjoy playing with mirrors.

2.Why does the author mention apes and dolphins in the text?

A.They are most familiar to readers.

B.They are big favorites with zoo visitors.

C.They are included in the study by Reiss.

D.They are already known to be intelligent.

3.What made Happy different from Maxine and Patty?

A.She used her nose to search behind the mirror.

B.She recognized her own image in the mirror.

C.She painted a mark on her own face.

D.She found the hidden camera.

【答案】

1.B　细节理解题。根据第二段第一句可知，通过研究动物是否在镜子中识别自己可以测试它们的自我意识。

2.D　推理判断题。根据第二段最后一句可知，作者提到猿和海豚是因为它们和人一样可以识别镜中自己的形象，是人们已知的有智力的动物;再根据第三段，一个亚洲象也通过了该测试，也加入到有智力的行列里，故选D项。

3.B　细节理解题。根据倒数第二段，三个大象中只有Happy通过了镜子测试，也就是说只有她能识别镜中自己的形象，因此这是她有别于其他大象的地方，故选B项

Think about the different ways that people use the wind.You can use it to fly a kite or to sail a boat.Wind is one of our cleanest and richest power sources (来源), as well as one of the oldest.Evidence shows that windmills (风车) began to be used in ancient Iran back in the seventh century BC.They were first introduced to Europe during the 1100s, when armies returned from the Middle East with knowledge of using wind power.

For many centuries, people used windmills to grind (磨碎) wheat into flour or pump water from deep underground.When electricity was discovered in the late 1800s, people living in remote areas began to use them to produce electricity.This allowed them to have electric lights and radio.However, by the 1940s when electricity was available to people in almost all areas of the United States, windmills were rarely used.

During the 1970s, people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity.People also realized that the supply of coal and gas would not last forever.Then, wind was rediscovered, though it means higher costs.Today, there is a global movement to supply more and more of our electricity through the use of wind.

1.From the text we know that windmills ________.

A.were invented by European armies

B.have a history of more than 2,800 years

C.used to supply power to radio in remote areas

D.have rarely been used since electricity was discovered

2.What was a new use for wind power in the late 19th century?

A.Sailing a boat.

B.Producing electricity.

C.Grinding wheat into flour.

D.Pumping water from underground.

3.One of the reasons wind was rediscovered in the 1970s is that ________.

A.wind power is cleaner

B.it is one of the oldest power sources

C.it was cheaper to create energy from wind

D.the supply of coal and gas failed to meet needs

4.What would the author probably discuss in the paragraph that follows?

A.The advantages of wind power.

B.The design of wind power plants.

C.The worldwide movement to save energy.

D.The global trend towards producing power from wind.

【答案】

1.C　细节理解题。根据第二段的“When electricity was discovered in the late 1800s, people living in remote areas began to use them to produce electricity. This allowed them to have electric lights and radio.”可推出，C项符合题意。

2.B　细节理解题。根据第二段的“When electricity was discovered in the late 1800s, people living in remote areas began to use them to produce electricity.”可知，B项符合题目要求。

3.A　细节理解题。根据第三段的“people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity”可知，A项符合题意。

4.D　推理判断题。第三段最后已提出现在全球已越来越多地使用风力发电，所以下一段应该要进一步推广使用风力发电，这是一种总体的能源发展趋势。故D项正确。
