Ⅶ.阅读理解
Wind power is a very clean source of energy. This is how wind power works. Wind makes windmills spin(旋转). 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 true. For 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. It used to be true, but it isn't true any more. 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.
(　　)35.Why DON'T new windmills kill birds Because ________．
A．birds don't fly near them
B．they spin slowly
C．they are shorter than old windmills
D．new windmills don't spin
(　　)36.When did people start using wind power
A．About 25 years ago. B．About 80 years ago.
C．About 500 years ago. D．Over 1，000 years ago.
(　　)37.________， 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
D．Wind doesn't blow all the time
(　　)38.What does the article say about wind power
A．Most people don't like it.
B．It's getting cheaper.
C．Denmark doesn't use it.
D．It's getting more expensive.
(　　)39.What is the best title for the passage

B．Cheap and Clean Energy
C．Popular and Clean Wind Power

Ⅵ.[主旨大意] 本文为一篇说明文，首先指出废水问题很严重；然后说明了解决废水问题的重要性；最后给出了解决废水问题的方法。
27．B　动词的词义辨析。drink 意为“喝”；save意为“节约”；carry意为“扛，抬”；watch意为“观看”。句意：它不仅使我们考虑水的重要性，还号召我们节约水，保护水。
28．D　形容词的词义辨析。easy意为“容易的”；popular意为“受欢迎的”；small意为“小的”；serious意为“严重的”。根据上句中的terrible可知，废水问题很严重。
29．A　名词的词义辨析。结合语境可知废水的来源有工厂。
30．C　动词短语的词义辨析。get back意为“回来”；hand in意为“上交”；change into意为“变成”；pick up意为“拾起，捡起”。句意：在暴风雨中，当雨水流过街道时也会变为废水。
31．B　复合不定代词的辨析。句意：无论它来自哪里，这种水中一定含有某些有害的物质。something意为“某些东西”，表示肯定的意思。
32．C　特殊疑问词的辨析。句意：我们为什么必须处理废水？下文列举了废水的危害，因此用why提问处理废水的原因。
33．C　名词的词义辨析。work意为“工作”；interest意为“兴趣”；health意为“健康”；business意为“商业”。句意：我们必须在意我们的环境和我们自己的健康。根据上句中的illness可知选C。
34．A　形容词比较级的辨析。less意为“更少”；more意为“更多”；better意为“更好”；worse意为“更糟糕”。来自家庭的废水被再次利用，废水会变得更少。
Ⅶ.[主旨大意] 本文是一篇说明文。文章主要介绍了风能这种清洁能源以及风车。风能是通过风使风车旋转发电来让我们获得能量的。风能并不是一种新能源，早在古代人们就利用风能来行船、取水等。很多人认为人类应大力应用风能，因为它有很多优点；但也有一些人对风能持不同观点。风车也的确有些问题，比如风车不美观、有噪音等。但无论如何，风能越来越普遍，已占到世界总能量的2.5%，在丹麦占的比重高达25%。
35．B　细节理解题。由第四段最后一句话“New windmills spin slowly, and they aren't dangerous for birds.”可知，新的风车因其旋转得很慢，因此它们不再会杀死鸟类，
36．D　细节理解题。根据第二段第二句“For thousands of years, people have used wind to sail boats and move water.”可知，人类运用风能有一千多年了，
37．D　细节理解题。根据第五段倒数第二句“Also, wind doesn't blow all the time, so we can't use wind power all the time.”可知，因为风并不总是在刮，因此我们不能一直使用风能，
38．B　细节理解题。根据第三段最后一句“Also, wind power is cheap, and it's getting even cheaper.”可知，文章指出风能是便宜的，并且正在变得更加便宜，
39．C　主旨大意题。通读短文可知本文介绍了风能的相关情况，风能是一种清洁的能源，正在变得很普及，因此选项C的描述“受欢迎又干净的风能”最为恰当，
