How to Be a Green One What does it mean to be green? “Green” is more than just a 1     It also means taking special steps to protect the environment —the water,the land and the air we breathe. Why green plants are green,and 2     them the earth wouldn’t be such a lovely home for us human beings. Here’s a four-step guide to being green : Reduce It!

When  you use less of something,you do a good thing for the earth. For example,a shorter shower means you use 3     water and less fuel (燃料) 4     your house use fuel to run the water heater that warms up the water.

Reuse It!

Sometimes we’re a little too willing to throw away old things and buy new things. Many times,if you no 5     need something,someone else just might need it. For example,if your baby brother grows out of 6        , why not give them to another family who has a little kid?

Recycle It!

Recycling has never been easier. Leave the things which you do not need right in front of your house and someone who needs them will 7     them up. Tell your parents you want to become “ Head of Recycling ” for your house and tell others 8     things can be recycled.

Enjoy It!

It’s 9     that pollution is a problem, but the earth remains a huge and beautiful place for you to go and study. You can start by 10     the naturally beautiful places in your hometown. Go for a hike,visit local nature centres and gardens,climb up mountains and so on.

   In the past,man did not have to think about the protection of the environment.  1     Today things are different. The world has become too crowded. We are using up our natural resources too quickly and at the same time we are polluting our 

environment with dangerous chemicals. 2     Everyone realizes today that if too many fish are taken from rivers and the sea,there will soon be none left. 3     We know that if too many trees are cut down,forests will disappear and nothing will grow on the earth. Yet we continue to use bigger and more powerful machines to cut down more and more trees.

   We realize that if rivers are polluted with waste products from factories,fish will die. However,in most countries waste are still put into rivers or the sea,and there are few laws to prevent this. Also,we know that if the population of the world is becoming larger and larger,in a few years there will not be enough food. 4    

   If we eat more vegetables and less meat,there will be more food for everyone. 5     The world population will not rise so quickly if people use modem methods of birth control.

   Finally,if we educate people to think about the problems,we shall have a better and cleaner planet in the future. In a word,it is very important to protect our environment.

科目: 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.

C. Reducing 95% of the waste.

D. Cutting off rubbish from the surrounding environment.

(   ) 3. Paragraph 6 is mainly about         .

A. the separation of rubbish

B. the problems with burning rubbish

C. the safety of burning rubbish

D. the cost of burning rubbish

(   ) 4. The best title of the passage is         .

A. Cutting out waste

B. Recycling waste

C. Burning waste

D. Burying waste

   It’s very important that we all recycle (再利用).In nature,everything 1    again. For example,when an animal dies,it becomes  2     animal’s food. Nothing is

wasted. But humans have created things like plastic bags 3     can’t be broken down by nature. Our rubbish kills animals and 4     water and soil. 5 we continue making too much rubbish,the problem will only get worse. If nature can’t reuse the rubbish,we must recycle 6     We should clean up the rubbish we’ve made because nature can’t.

  Recycling is also the right thing to do for another reason. The earth is rich in natural materials like water and trees,7      these materials are not endless. We

use up our natural materials much 8     than the earth is able to reproduce them. For example,each year we cut 9     more than 6,000 square miles of forest. But it takes an average of 25 years for a new tree 10      .

Recycling can help us save the earth,so let’s take actions right now.
