問題詳情：

Wind power is a very clean source of energy. This is how wind power works. Wind makes windmills spin (旋轉). When the windmills spin, they make electricity. Then we can use the electricity.A lot of people think that wind power is new, but that’s not thousands of years, people have used wind to sail boats and move water. We still do those things today, but these days we mostly use wind power to make electricity.

Wind power is a very popular source of energy. Most people think that we should use it more and more. First of all, it’s clean. Windmills don’t pollute the environment at all. Second, we can use wind power forever. After all, we will always have wind. Also, wind power is cheap, and it’s getting even cheaper.

A lot of people don’t understand wind power very well. They believe that there are problems with wind power, but many of those problems are not real. For example, some people say that windmills are dangerous for birds. They used to be true, but it isn’t true anymore. Old windmills killed birds because they spun very fast. New windmills spin slowly, and they aren’t dangerous for birds.

However, there are real problems with windmills. One problem is that many people think windmills are very ugly. This is a problem for people, because windmills are often in very pretty areas. Also, wind doesn’t blow all the time, so we can’t use wind power all the time. Finally, windmills are noisy.

Wind power is becoming more and more common. Right now, more than 80 countries use wind power. About 2.5 percent of the world’s power comes from the wind. For some countries, that number is a lot higher. Wind power gives Denmark more than 25 percent of its electricity.

C. About 500 years ago.                       D. Over 1,000 years ago.

33.                         , so we CAN’T use wind power all the time.

A. Windmills break all the time               B. We can’t use windmills at night

C. Windmills are too expensive to use all the time  D. Wind doesn’t blow all the time

34. What does the article say about wind power?

A. Expensive Windmills                        B. Cheap and Clean Energy

C. Popular and Clean Wind Power               D. Dangerous Birds

【回答】

31.B

【解析】細節理解題。根據第三段中的句子“Old windmills killed birds because they spun very fast. New windmills spin slowly, and they aren’t dangerous for birds.” 舊風車殺死鳥是因為它們旋轉得很快。新的風車旋轉緩慢，對鳥類來説並不危險。故*為B。

32.D

【解析】細節理解題。根據第一段中的句子“For thousands of years, people have used wind to sail boats and move water.”幾千年來，人們藉助風帆來航行和通過風車來灌溉。因此藉助風力至少有一千多年的歷史，只有D選項符合題意。

33.D

【解析】細節理解題。根據倒數第二段中的句子“Also, wind doesn’t blow all the time, so we can’t use wind power all the time.”風不會一直吹，所以我們不能一直使用風力。故*為D。

34.B

【解析】細節理解題。根據第二段中的句子“Wind power is a very popular source of energy.”可知，風能是一種非常流行的能源，A選項錯誤；根據第二段中的句子“Also, wind power is cheap, and it’s getting even cheaper.”可知風能很便宜，而且越來越便宜。B選項正確，D選項錯誤；根據最後一句“Wind power gives Denmark more than 25 percent of its electricity.”風力發電為丹麥提供了超過25%的電力。C選項錯誤。故*選B。

35.C

【解析】標題歸納題。短文介紹了人類對風能的利用。風能是一種非常清潔的能源，也是一種非常流行的能源。故*為C。
