By the end f the class, we will be able t:
In the last lessn, we learned abut kinds f pllutin and what we can d t cut them dwn. D yu have the awareness f envirnmental prtectin in yur daily life? List sme examples.
Hw much waste d yu r yur family prduce every day?What des the waste cntain r where is it frm? Hw d yu usually deal with the waste?
Mst f the time we just thrw away the waste. Can yu think f sme envirnment-friendlier ways t deal with waste? Or what can we d t reduce the waste?

1. Lk at the pictures n this page. Say which ways are gd fr the envirnment and why.
Reading and vcabulary
dispsable plastic meal bxes(一次性塑料餐盒)

2. Lk at the title f the passage. What suggestins d yu think the passage will make? Use the wrds in the bx t help yu.
It is better t use china cups and bwls because they can be used many times.
3. Read the passage and answer the questins in the first part.
Hw t be greenHw green are yu? Answer these questins and find ut. D yu walk r ride a bike t schl?D yu buy new clthes just because they are mdern?D yu turn ff the lights when yu leave the rm?D yu take yur wn bag when shpping and nt ask fr a plastic bag? D yu buy drinks in bttles? And what d yu d with the bttles when they are empty? D yu divide the waste int things t recycle and things t thrw away?
We all need a healthy envirnment, but we prduce waste every day, and it is harmful t ur envirnment. Repeat these three wrds daily: reduce, reuse and recycle. 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. Buy prducts such as recycled paper t help save trees. We cannt hpe fr rapid change, but let's take these simple steps tday s that we will save the wrld fr ur grandsns and granddaughters tmrrw.
