Wind power is a very clean source of energy. This is how wind power works. Wind makes windmills spin. 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. That used to be true, but it isn't 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, many countries use wind power. About 8 per cent of the world's power comes from the wind. For some countries, that number is a lot higher. Wind power gives Denmark about 50 per cent of its electricity.

【分析】
做这几道英语阅读理解题时，需先根据题干关键词定位原文对应段落，再将选项与原文内容逐一比对，排除错误选项得出答案。第1题定位新风车与鸟类安全的段落，第2题定位风能无法持续使用的原因，第3题核对原文对风能的描述，第4题总结全文主旨。
【解析】
1. 第1题：根据题干关键词“new windmills kill birds”定位到文章第四段最后一句“New windmills spin slowly, and they aren't dangerous for birds.”，可知新风车旋转缓慢，因此不会伤害鸟类，对应选项B。A选项文中未提及鸟类不靠近新风车，C选项未提到新风车比旧风车矮，D选项“不旋转”与原文矛盾，故答案为B。
2. 第2题：根据题干关键词“can't use wind power all the time”定位到文章第五段“Also, wind doesn't blow all the time, so we can't use wind power all the time.”，直接明确原因是风不会一直吹，对应选项D。A选项未提及风车频繁损坏，B选项“夜间不能用”无依据，C选项“太贵”与原文不符，故答案为D。
3. 第3题：逐一核对选项：A选项与第三段“Wind power is a very popular source of energy. Most people think that we should use it more and more.”矛盾；B选项与第三段最后“Also, wind power is cheap, and it's getting even cheaper.”一致；C选项与最后一段“Wind power gives Denmark about 50 per cent of its electricity.”矛盾；D选项与原文“getting even cheaper”矛盾，故答案为B。
4. 第4题：文章围绕风能展开，介绍了风能的清洁性、受欢迎程度、价格优势及实际应用等，A选项“昂贵风车”与原文不符，B选项仅概括部分内容，D选项是错误信息，C选项全面概括主旨，故答案为C。
