How to be green

We all need a healthy environment, but we produce waste every day, and it is harmful to our environment. Repeat these     1     words daily: reduce, reuse and recycle.

Reduce means “use less”. Do not waste things. It saves money and     2     less pollution. Do not order more food than you can finish. Turn     3     the lights when you do not need them. Before you buy something new, think     4     it is really necessary because maybe the old one is just as good!

Reuse means “use again”. Use things for as     5     as possible. Look after them so that they will last. Repair them if possible. Do not throw them away and buy new ones. Do not use paper cups or paper bags. It is better to use china cups and     6     bags because they can be used many times.

Recycle means “change things into something else to be reused”. Although it takes energy to change things     7     something else, it is better than throwing things away or burning them. We throw     8     of rubbish away each year, and we have to make a change. Divide your rubbish into plastic, glass, paper and rubber.     9     a recycling policy for the whole community. Buy products such as recycled paper to help save trees.

We cannot hope for     10     change, but let’s take these simple steps today so that we will save the world for our grandsons and granddaughters tomorrow.

Our clothes are usually made of cotton or wool. Some students in Shandong did something     1    . They wore the clothes made of discs(光盘) or old clothes!

Last year, some students in Linyi, Shandong Province, wore beautiful clothes in a fashion show.    2     clothes were made of many kinds of things. The show gave the students opportunity(机会)    3       things by hands.It also helped them learn to make good use of waste and not to throw some old things away .

Students had lots of good ideas. To make   new dresses,some found the things that    4    like old clothes, old newspapers, old discs and so on.

" Our world is short of energy     5    .We hope to save energy. "said Xie Hong at Linyi Art School. Xie had     6     than 20 discs on her nice blue dress. She got them from her friends ."Though the discs are old. I look very cool in them!” she said.

Zhang Jing, a student from the school looked like a     7     in her straw(稻草)coat and hat. She picked the straw     8     the fields and put them all together. "I want to show what people wore in the past. "she said.

Wu Yue made clothes for     9    . She had white cloth all over her. She tried to walk as slowly as possible. It looked like she was walking on the moon. "I hope I     10     it in space some day. I wish that I could walk on the moon!"she said.

The total amount of carbon dioxide (CO2) you produce a year is called your     1    . Besides breathing, there are two other ways you can produce CO2. First, you can do it directly, by driving a car or using a gas stove.     2    , you can do it indirectly, by buying or using products that produced CO2 when they were made.

Generally, you should make your carbon footprint     3     possible. For example, you can use public transport     4     a car, or you can walk or cycle.

More and more people, both young and old, are becoming greener today. This means they are trying to protect the environment in     5    . Let's see how green you are!

The environment is becoming worse and worse. There are many kinds of     1     that I worry about. The most terrible two are     2     pollution and air pollution, because people can’t live healthily with     3     water and polluted air. Animals can’t live in the world, either. More and more people are becoming ill     4     of polluted air. I think factories shouldn’t pour（倒）dirty water     5     rivers directly or produce so much waste gas. We’d better go on foot or by bike     6     of by car. Finally, everybody must pay     7     to rubbish pollution. If everybody     8     so much rubbish , one day we may live in the world which is     9     of rubbish. How terrible it will be! We should take action to make our world     10     and more beautiful.
