Question

  Taking away a city’s rubbish is a big job．Every day trucks come into a city to collect it．Most rubbish is made up of things we can’t eat or use．If we kept these things, we would soon have a mountain of rubbish．

In some cities the rubbish is collected and taken outside of city to a dump．Often the city dump is placed where the ground is low or there is a big hole．The kitchen rubbish is broken into small pieces and sent into the sewage system．The sewage system takes away the used water from toilets, bathtubs and other places．

To keep mice and flies away, some earth is used to cover the newly dumped rubbish．Later, grass may be planted on the rubbish-filled land．Finally , a house or a school may be built there, and then you’d never know that this had once been an old rubbish dump．

In other cities the rubbish is burnt in special places．The fire burns everything but the metal．Sometimes the metal can be used again in factories where things are made of metal．The food parts of rubbish are put in special piles where they slowly change into something called humus, which looks like black earth．It is rich with kinds of things that feed plants and help make them grow．

试题分析：短文大意：这篇文章主要讲了带走城市的垃圾是一件巨大的工程，垃圾被放到远离城市之外，垃圾都是放在低地或大坑里面，在这些垃圾的上面可以种草或建造房屋。在垃圾中有一部分是金属可以回收利用，一些垃圾是可以成为其他植物的食物。

1.A词义猜测题。根据本句句意The sewage system takes away the used water from toilets, bathtubs and other places.带走厕所浴室和其他地方的污水，可知应该是排污水水系统，可知选A。

2.B细节理解题。根据文中最后一段The food parts of rubbish are put in special piles where they slowly change into something called humus, which looks like black earth. It is rich with kinds of things that feed plants and help make them grow可知一些垃圾可以成为其他植物的食物。故选B。
