【答案】F；D；C；E；B
【解析】随着科技的发展，我们的生活比以前更加的便利了，但是也带来了一些新的问题，例如污染，水污染、空气污染噪音污染等等。这篇短文尤其提到了最严重的污染—空气污染，并对人们提出了建议。

①上文说到Life today is easier than it was hundreds of years ago, but it has brought some new problems.我们现在的生活比几百年前更方便了，但是也带来了一些新的问题，因此这个空应具体说明带来了什么问题。再根据下文Man has polluted the earth. The more people, the more pollution可知，这里说的问题是污染。故应选F。

②根据上句话The more people, the more pollution. 可知，人口越多，污染越多。这个空后面又提到the problem was not so serious.问题不是那么严重，还使用了一般过去时态，因此这里是说很多年前人口没有那么多，故应选D。

③根据下文Many countries don't let burn something bad for air in houses and factories in the city.可知，这里提到的是空气污染的问题，故应选C，空气污染仍然是最严重的。

④上文说到交通拥挤会导致空气污染，下句话提到When you are riding, there is no pollution当你骑自行车的时候，就没有污染。因此这句话建议人们骑自行车，故应选E。

⑤根据上下文的意思可知，这里仍然在说的话题是让人们骑自行车，因此选项中B跟这个话题是有关的，我们应该有自行车的专用道路，这样能跟下面的句子连贯起来，make it so difficult and expensive for drivers to take their cars into the city让司机们开车比较困难和昂贵，这样开车的就少了，骑自行车的多了，对空气污染是有好处的。
