科目:初中英語 來源: 題型:

 Rubbish is a major kind of environmental pollution. Each person produces about two kilograms of rubbish in our homes a day. And this is only a small part of all the rubbish we produce. We also create waste in industry (工業(yè)). Have you wondered what happens to the rubbish?

   Most of it is buried (填埋)in landfills (垃圾填埋廠)or burned. Less than 25% of our waste is recycled.

   A landfill is carefully designed and it is built into or t  on top of the ground. Rubbish buried in landfills is cut off from the surrounding environment, such as

 groundwater,air,rain,etc.

   One problem with landfills is that they cover a lot of land  space. If they are not well built,there is a high risk of polluting the land and water. Some people also

 say that landfills remove materials for ever. As a result, the materials that can be reused are wasted.

    Burning rubbish in factories is another way to cut 1  out waste. Burning reduces 95% of the waste. And if poisonous (有毒的)materials are removed,and burning is completed at controlled temperatures,it’s possible to do so without causing too much pollution. Some factories could even produce electricity from the burning process

(過程).

    Not all of the rubbish can be burned,so we have to [separate it before we burn it. However,separation costs a lot of money. Another problem with burning rubbish is that what is left after burning is poisonous. How to safely deal with it is a continuing problem.

    Before the mid - 20th century,landfills were the main way to deal with waste. In the late 20th century,other ways like recycling have been introduced to help reduce global (全球)pollution.

根據(jù)材料內(nèi)容選擇最佳答案。

(   ) 1. How many ways do people  do  deal with rubbish?

A. Two. B. Three. C. Four.  D. Five.

(   ) 2. What is the advantage of burying  rubbish in landfills?

A. Producing electricity.

B. Reusing the materials buried in landfills.

D. Cutting off rubbish from the surrounding environment.

(   ) 3. Paragraph 6 is mainly about         .

A. the separation of rubbish
