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. 阅读理解1. 让学生读短文的第一、二段，然后用课件或小黑板展示下列句子，让学生根据阅读的内容补全下列句子：(1) There are trees, flowers, rivers and on the earth.(2) We cut down trees.(3) We waste water and make the air.参考答案：(1) many, mountains (2) too many (3) too much, dirty2. 教师让学生勾画出各自在阅读课文时遇到的不熟悉的词语，先请同学们根据语境猜猜这些词语的意思，之后教师解疑答惑，讲解短语care for, do bad things to.（1）care for关心、爱护；如：Alice has a white rabbit and she cares for it.（2）do bad things to对做坏事，损坏；如：We are friends. We shouldnt do bad things to each other.教师鼓励学生试着用care for、do bad things说话，或教师给出汉语让学生说出英语：1. 爸爸妈妈都很爱护我。2. 我们要爱护这些小树木。3. 人们不应该做损害我们地球的事情。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）让学生以组为单位讨论many, too many, much，too much的用法，最后由教师进行汇总概括。教学小贴士many, much, too many, too much 的用法1. many和much都表示“许多”。但many修饰可数名词，much修饰不可数名词。many和much都可以用a lot of替换，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表示强调，意为“太多”。用法与many，much 基本相同，不同的是too much可作副词短语，用来修饰动词。如：I eat too much, so I dont feel good. （修饰动词eat）There is too much bread on the table. （修饰名词bread）Im very busy today, because I have too many things to do.（修饰名词things）iii. 巩固活动1. 教师播放录音，学生集体跟读课文，教师注意纠正学生的发音问题。2. 学生通读短文，完成Read again and tick or cross部分的练习。参考答案：1. 2. 3. 4. 5.
