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 whey 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. 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.
【知识点1】clothes，cloth与clothing的用法：
①clothes意为“衣服”，统指各种衣服，是一个没有单数形式的复数名词，谓语动词是复数，其前不可加不定冠词，也不可加数词，但可用some, these, those, many, few等词修饰。如：
I need to buy some clothes. 我需要买一些衣服。
②cloth指布，常用作不可数名词，a piece of cloth意为“一块布”，如指有特殊用途的布时则为可数名词，复数形式为cloths。如：
Clean the windows with a soft cloth. 用块软布擦窗子。
③clothing表示“衣服”的总称，是一个不可数的集合名词。如：
They wear very little clothing. 他们衣服穿得很少。
They don’t have enough to make these .
A. cloth; cloth B. cloth; clothes
C. clothes; cloth D. clothes; clothes
B
【知识点2】do with与deal with的用法：
①do with意为“处理，处置，对付”，do是及物动词，后可接宾语，因此do with要与可作宾语的疑问代词what连用，构成特殊疑问句。What do you do with… 意为“你怎样处理……？”。如：
I don’t know what they will do with the problem.
=I don’t know how they will deal with the problem.
我不知道他们将如何处理这个问题。
②deal with意为“处理，处置，对付”，因此要与疑问副词how连用，构成特殊疑问句。如：
What do you do with the matter
=How do you deal with the matter 你如何处理这件事情？
1. Jane is very bust these days, for he has a lot of problem to .
A. deal with B. keep up with C. agree with D. come up with

【知识点3】divide与separate的用法：

A year is divided into four seasons. 一年分为四季。
Please divide the apple into four pieces. 请把这儿苹果分成四块。
②separate常与from连用，表示“把……从……分离”，指把原来连在一起或靠近的各个部分隔开，被分隔开的对象没有统一性。
The two countries are separated by a river. 这两个国家相隔一条河。
In the fog, they got separated from the team.
他们和团队在雾中分开了。
Our English teacher us five groups and ask us to practise the dialogue.

D
【知识点4】throw away意为“扔掉；丢弃”。该短语是“动词+副词”结构的短语，当宾语是代词时，代词要放在短语中间。与throw连用的常见搭配：throw about乱丢，乱扔；throw at投向；throw back扔回；throw oneself into sth.积极投身入某事中去。如：
Don’t throw away those boxes. 不要把那些箱子扔掉。
The food got bad. I have thrown it away.
那食物坏了。我把它扔掉了。
The meat smells bad and you’d better .
A. throw away it B. throw it away
C. throw away them D. throw them away
B
【知识点5】be harmful to= do harm to=be bad for意为“对……有害”。其反义词为do good to=be good for，意为“对……有好处”。harmful是形容词，意为“有害的”，其反义词是harmless意为“无害的”。其名词和动词形式都是harm意为“伤害；害处”。如：
Smoking is harmful to/does harm to your health.
抽烟对你的健康有害。
Watching TV too much is harmful to/does harm to your eyes.
看电视太多对你的眼睛有害处。
Exercise will do good to your health. 锻炼将对你的健康有益。
