【解析】

短文大意：现在的生活比数百年前更容易了，但它也带来了一些新的问题。最大的问题之一是空气污染。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.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是固定用法，故选B。

2.考查动词及语境理解。listen听，是一个非及物动词，常与to搭配使用，强调听的动作过程；hear of听到，听说；hear听，听见，是一个及物动词，强调听的结果。根据We can see it, smell it, drink it and推知，故选D。

3.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。故选C。

4.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，故选C。

5.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，故选D。

6.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，故选A。

7.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，故选C。

8.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，故选A。

9.考查名词及语境理解。water水；air空气；noise噪音；white白色，白色的。根据常识二氧化硫污染是最危险的空气污染可知。故选B。

10.考查形容词及语境理解least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，故选B。

11.考查动词及语境理解。驾驶汽车用drive，骑自行车用ride。跳读知句意：人们骑自行车，没有污染。根据前面的are可知，此空用现在分词，故选C。

12.考查疑问词及语境理解。why为什么；because因为；what什么；how怎么。根据句意这不是因为自行车贵，故选B。

13.考查动词短语及语境理解put on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，故选C。

14.考查形容词及语境理解。better and better越来越好；more and more 越来越多；worse and worse 越来越坏；bigger and bigger越来越大。根据前句more people put away their bikes and go to work by cars（更多的人收起他们的自行车而开车去工作）知,本句句意为，情况变得越来越糟，故选C。

15.考查副词及语境理解。quite很，非常；such如此，常用在名词前；very 非常，很；so如此，常用在形容词或副词前。such…that，so..that，都译为如此…以至于，由于difficult为形容词，故用so。故选D。
