【解析】

试题分析：现在的生活比数百年前是更容易了，但它也带来了一些新的问题。最大的问题之一是空气污染。告知人们为了人类，为了后代，我们必须要保护我们的家园——地球。

1.B考查数词及语境理解。表示整百时hundred不用复数，也不跟of连用，但表示概数时，hundred必须用复数，并且跟of连用。数百年前hundreds of years ago是一固定用法，所以选B。

2.C考查名词及语境理解。Moon月球；star 星；earth 地球；sun 太阳。结合句意人类已污染了地球可知选C。

3.C考查形容词及语境理解lot 很多；little 很少，几乎没有；many 许多，修饰可数名词复数；much 许多，修饰不可数名词。根据上句The more people, the more pollution.（人越多，污染越多）可知本句句意为：许多年前，这问题不严重是因为没有如此多的人，people是复数名词，所以选C。

4.D考查代词及语境理解。others 其他的，泛指；the others 其他的，特指；the other 另一，指两者当中的另一者；another另一，指多数当中的另一者。根据上句When the land was used up, the river was not clean in a place,（当土地被用光，那地方的河流不干净时）知本句句意为：人们就去了另一个地方，所以选D。

5.A考查名词及语境理解。 Air 空气；Food 食物； Water 水；Noise噪音。跳读知句意：现在，人类正在慢慢地污染整个世界，空气污染仍然是最严重的，所以选A。

6.C考查名词及语境理解。life 生活，复数为lives；live 居住，现在分词为 living ，第三人称

单数为lives 。living things生物，是一固定说法，所以选C。

7.A考查不定代词及语境理解。something 某事，某物；bad 坏的； good 好的；形容词修饰复合不定代词要放在后面。跳读知句意：许多国家不允许人们燃烧废物，所以选A。

8.B考查形容词及语境理解。east 最少的； best 最好的；most 最多的；worst 最坏的。跳读知句意：人们说最好骑自行车，所以选 B。

9.C考查动词短语及语境理解。puton穿，戴；look at 看；put away 收起，放好；look up向上看，在字典参考书中查找。根据前句It’s because the number of cars on the roads becomes larger.（这是因为道路上的汽车数量变大） 知本句意为更多的人收起他们的自行车而开车去工作，所以选C。

10. 考查连词短语及语境理解。so..that，都译为如此……以致，由于difficult为形容词，故用so。所以选 D。

考点：科普环保类短文。
