Language pints
Reduce Reduce means “use less”. D nt waste things. It saves mney and causes less pllutin. D nt rder mre fd than yu can finish. Turn ff the lights when yu d nt need them. Befre yu buy smething new, think whether it is really necessary, because maybe the ld ne is just as gd!Reuse Reuse means “use again”. Use things fr as lng as pssible. Lk after them s that they will last. Repair them if pssible. D nt thrw them away and buy new nes. D nt use paper cups r paper bags. It is better t use china cups and clth bags because they can be used many times.
Recycle Recycle means “change things int smething else t be reused”. Althugh it takes energy t change things int smething else, it is better than thrwing things away r burning them. We thrw tns f rubbish away each year, and we have t make a change. Divide yur rubbish int plastic, glass, paper and rubber. Develp a recycling plicy fr the whle cmmunity.

【知识点1】clthes，clth与clthing的用法：①clthes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sme, these, thse, many, few等词修饰。如： I need t buy sme clthes. 我需要买一些衣服。②clth指布，常用作不可数名词，a piece f clth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clths。如： Clean the windws with a sft clth. 用块软布擦窗子。③clthing表示“衣服”的总称，是一个不可数的集合名词。如： They wear very little clthing. 他们衣服穿得很少。

【知识点2】d with与deal with的用法：①d with意为“处理，处置，对付”，d是及物动词，后可接宾语，因此d with要与可作宾语的疑问代词what连用，构成特殊疑问句。What d yu d with…? 意为“你怎样处理……？”。如： I dn’t knw what they will d with the prblem. =I dn’t knw hw they will deal with the prblem. 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hw连用，构成特殊疑问句。如： What d yu d with the matter? =Hw d yu deal with the matter? 你如何处理这件事情？

Our English teacher us five grups and ask us t practise the dialgue. A. turns; int B. fits; int C. puts; int D. divides; int
【知识点4】thrw 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thrw连用的常见搭配：thrw abut乱丢，乱扔；thrw at投向；thrw back扔回；thrw neself int sth.积极投身入某事中去。如： Dn’t thrw away thse bxes. 不要把那些箱子扔掉。 The fd gt bad. I have thrwn it away. 那食物坏了。我把它扔掉了。
The meat smells bad and yu’d better . A. thrw away it B. thrw it away C. thrw away them D. thrw them away
【知识点5】be harmful t= d harm t=be bad fr意为“对……有害”。其反义词为d gd t=be gd fr，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： Smking is harmful t/des harm t yur health. 抽烟对你的健康有害。 Watching TV t much is harmful t/des harm t yur eyes. 看电视太多对你的眼睛有害处。 Exercise will d gd t yur health. 锻炼将对你的健康有益。

【知识点7】tns f意为“大量，许多的，一大堆（口语）”，后可接可数名词复数或不可数名词，用来形容数量很大。tn是量词，意为“吨”。拓展tns f位于数词后，表示具体的吨数，a tn f...意为“一吨……”；tw tns f...意为“两吨……”。如： I have tns f things t d. 我有很多事情要做。 I bught tns f fruit while it was cheap. 当水果便宜的时候，我买了大量的水果。 We stred up ten tns f cal fr the winter. 我们为过冬储备了10吨煤。 Each stne weighs abut tw tns. 每块石头重约二吨。
