One solution is to make their school a green school.Lingling: After our lesson on the environment, I'm
worried about the future. Pollution is our
great enemy, and we have to fight it. If the
rivers are polluted, farmers can't use the water
for their crops.

spreads over cities and villages. It makes people
ill, and may even kill them. Pollution is a danger
to our health.

use so much oil and cause pollution as well.
Listen and read.Daming: But we're only students. We can't do
anything about factories and cars.
Betty: It's no use talking about things we can't
do.We've got to think of things we can do!
Daming: Such as...?
Lingling: Do you think we can make our school a
green school?
Daming: What's a green school?
Lingling: At a green school, every class collects
waste which can be recycled or used
again.
Then the school sells the waste and uses the money to help students in poor areas.
Daming: Nice idea!
Betty: Students at a green school also learn ways
to save energy and recycle at home.That means
less waste.
Tony: That’s s good idea. Though pollution is heavy now,
I don’t think it’s hopeless. If everyone starts to do
something, the world will be saved.

Reuse means “use again”.
Though pollution is heavy now, I don’t think
it’s hopeless. Make new words. Join the parts of words in Box A with the words in Box B．You need to use some of the parts more than once.
A
B care collect hope possible use
usual wanted waste-able -ful im- -less re- un- Learning to learn
Sometimes if you know the meaning of the parts of a word, you can work out the meaning of the whole word. re＋new＋able：re=again, able=can be，renewable=can be new again
构词法
1. 合成法
将两个或两个以上独立且语义不同的单词合在一起构成新词的方法叫做合成法。合成法是一种比较灵活的构词方法，可以合成名词、形容词、副词、代词、动词等。
例如：afternoon, sportsman, blackboard, sportsperson, newspaper,
airplane, classmate, grandfather 等就是通过合成构词法构成的名词；kind-hearted, middle-aged, hard-working 等为合成形容词；however, maybe, himself, everyone, nothing, overlook 等也都是通过合成法构成的单词。
2. 派生法 通过在词根前面加前缀或在词根后面加后缀构成一个新词的方法叫作派生法。要通过派生法理解和记忆单词, 我们需要掌握常见的前缀和后缀及派生规律。 常见前缀work out解决；计算；产生结果；设计出
这里的go为系动词。英语系动词的功能主要是把表语和主语联系在一起，说明主语的属性、特征或状态。系动词不能在句中独立作谓语，
必须和后面的表语一起构成句子的谓语。 某些含有变化意义的动态系动词如get, become, grow, turn等的进行时态可与形容词的比较级连用，表示渐进过程，其意思是“越来越……”。
eg：He is growing taller and taller.
他长得越来越高了。
Our life is getting better and better.
我们的生活越来越好了。
