We waste too much water and make the air dirty.Answer 2: We should care for our earth. We should do something to make the water and the air clean. We should plant more trees and help the animals.ii. 閱讀理解1. 讓學(xué)生讀短文的第一、二段，然后用課件或小黑板展示下列句子，讓學(xué)生根據(jù)閱讀的內(nèi)容補(bǔ)全下列句子：(1) There are trees, flowers, rivers and on the earth.(2) We cut down trees.(3) We waste water and make the air.參考答案：(1) many, mountains (2) too many (3) too much, dirty2. 教師讓學(xué)生勾畫出各自在閱讀課文時遇到的不熟悉的詞語，先請同學(xué)們根據(jù)語境猜猜這些詞語的意思，之后教師解疑答惑，講解短語care for, do bad things to.（1）care for關(guān)心、愛護(hù)；如：Alice has a white rabbit and she cares for it.（2）do bad things to對做壞事，損壞；如：We are friends. We shouldnt do bad things to each other.教師鼓勵學(xué)生試著用care for、do bad things說話，或教師給出漢語讓學(xué)生說出英語：1. 爸爸媽媽都很愛護(hù)我。2. 我們要愛護(hù)這些小樹木。3. 人們不應(yīng)該做損害我們地球的事情。My father and mother care for me very much.We should care for the small trees.People shouldnt do bad things to our earth.（3）讓學(xué)生以組為單位討論many, too many, much，too much的用法，最后由教師進(jìn)行匯總概括。教學(xué)小貼士many, much, too many, too much 的用法1. many和much都表示“許多”。但many修飾可數(shù)名詞，much修飾不可數(shù)名詞。many和much都可以用a lot of替換，但a lot of一般用于肯定句中。如：There are many people in the park during the holidays.There is much milk and juice in the fridge.2. too many, too much表示強(qiáng)調(diào)，意為“太多”。用法與many，much 基本相同，不同的是too much可作副詞短語，用來修飾動詞。如：I eat too much, so I dont feel good. （修飾動詞eat）There is too much bread on the table. （修飾名詞bread）Im very busy today, because I have too many things to do.（修飾名詞things）iii. 鞏固活動1. 教師播放錄音，學(xué)生集體跟讀課文，教師注意糾正學(xué)生的發(fā)音問題。2. 學(xué)生通讀短文，完成Read again and tick or cross部分的練習(xí)。參考答案：1. 2. 3. 4. 5.
