How to be green
By Wang Lingling
How green are you? Answer these questions and find out.
Do you walk or ride a bike to school?
Do you buy new clothes just because they are modern?
Do you turn off the lights when you leave the room? Do you take your own bag when shopping? and not ask for a plastic bag?
Do you buy drinks in bottles? And what do you do with? the bottles when they are empty?
Do you divide? the waste into things to recycle and things to throw away?？
We all need a healthy environment, but we produce waste every day, and it is harmful to our environment. Repeat these three words daily?： reduce, reuse and recycle. Reduce
Reduce means “use less”. Do not waste things. It saves money and causes less pollution. Do not order more food than you can finish. Turn off the lights when you do not need them. Before you buy something new, think whether it is really necessary because maybe the old one is just as good! Reuse
Reuse means “use again”. Use things for as long 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 cloth bags because they can be used many times. Recycle
Recycle means “change things into something else to be reused”. Although it takes energy to change things into something else, it is better than throwing things away or burning them. We throw tons of rubbish away each year, and we have to make a change. Divide your rubbish into plastic, glass, paper and rubber. 1011 Develop a recycling policy for the whole community. Buy products such as recycled paper to help save trees.
We cannot hope for rapid change, but let's take these simple steps today so that we will save the world for our grandsons and granddaughters tomorrow.12知识点3when shopping 当买东西时考向【易错点】 when＋doing，when为连词，由于主句和从句主语相同，故可省略从句中的主语和be动词。
