Question

The earth is our home. We must take care of it. Life today is easier then it was     years ago, but it has brought some new problems. One of the biggest problems is pollution. We can see it, smell it, drink it and even hear it.

Man has polluted the     . The more people, the more pollution. Many years ago, the problem was not so serous because there were not so     people. When the land was used up or the river was not clean in a place, man went to     place. Now man is slowly polluting the whole world.

     pollution is still the most serious, it’s bad for     things in the world.

Many countries don’t let people burn     for air in the houses and factories in the city. Pollution by SO2 is now the most dangerous kind of air pollution. It’s caused by heavy traffic. People say it’s     to ride bikes. When you are riding, there is no pollution. But even in developed countries, most people don’t go to work by bike. It’s not because bikes are expensive or people are tired if they ride to work. It’s because the number of cars on the roads becomes larger. So more people     their bikes and go to work by car, then things are getting worse and worse. We should have special roads only for bikes and make it     difficult and expensive for divers to take their cars into the city that they will go back to use their bikes.

试题分析：这篇短文主要讲述了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。文章告知我们：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，故选B。

2.C考查名词及语境理解。Moon：月球；star：星；earth ：地球；sun：太阳。根据语境可知，这里指的是人类已污染了地球。故选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.”的描述可知，这里指的是许多年前，这问题不严重是因为没有如此多的人，people是复数名词，故应选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,”的描述可知，这里指的是人们就去了另一个地方。故应选D。

5.A考查名词及语境理解。 Air ：空气；Food ：食物；Water：水；Noise：噪音。根据语境可知，这里指的是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，故应选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，故选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时，形容词要后置。根据语境可知，这里指的是许多国家不允许人们燃烧废物，故应选A。

8.B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。根据语境可知，这里指的是人们说最好骑自行车，故应选B。

9.C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.”的描述可知，这里指的是更多的人收起他们的自行车而开车去工作，故应选C。

10.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……以致，由于difficult为形容词，应用so。故应选D。
