8．要点点拨。
(1)We put on gloves and divided the garbage into different piles：glass，metal，plastic，paper and everything else.
divide v．分开，划分。常用短语：divide...into...，意为“把……分成……”，强调把原来是整体的东西分成若干份；divide...in half，意为“把……分成两半”，相当于divide...into halves。例：We should divide the apple in half.我们应该把苹果分成两半。
(2)I think it's our duty to protect the environment.
It's one's duty to do sth.意为“做某事是某人的职责/义务”。在这个句式中，it作形式主语，真正的主语是后面的不定式短语。例：It's her duty to look after her sick sister.照顾生病的妹妹是她的职责。

7．要点点拨。
(1)People throw too much away.
【辨析】too much、too many与much too
too much 太多，修饰不可数名词或动词，含有“过分，难以接受”之意。
too many 太多，修饰可数名词复数。
much too 太……，修饰形容词或副词。
(2)It is a waste to use paper only on the side.
it的用法：
①it作代词。it不仅可以指代具体的物品，而且还可以指代时间、距离、路程、天气等。例：It is half past five now.现在五点半了。
②it作形式主语。当句子的主语过长时，为避免头重脚轻通常将it置于句首作形式主语，而将真正的主语(通常是不定式短语、动名词或主语从句)放在句子的后面。例：It is important for us to use English as much as possible.对我们来说尽可能多地使用英语是很重要的。
③it作形式宾语。当句子的宾语过长时，常用it作形式宾语，用来代替真正的宾语(通常是不定式短语、动名词或宾语从句)。例：I found it hard to walk through the forest in five hours.我发现在五个小时之内穿越森林是件很困难的事。

②way在此作 “方式、方法” 讲，其后可接动词不定式(短语)、of短语及that/which引导的从句作定语。例：It's a good way to practice spoken English.＝It's a good way of practicing spoken English.＝It's a good way(that)you practice spoken English.那是一个练习英语口语的好方法。
(2)Turn off the television and shut down the computer when you are not using them.
①【辨析】turn off、turn on、turn up与turn down
turn off 意为“关掉，关闭”，一般指关闭电源、水等，后面常接电器、仪器等。

教学过程
环节1 新课导入
T：As is known to us，everything is connected to each other in nature.If one has something wrong，some bad facts will also happen to another.Do you want to know more about how everything is connected Today let's learn more about it.
设计意图：通过描述自然界的所有事物都是紧密相连的以及每种生物的重要性来引出本课时所要学习的内容。
环节2 新课学习
1．在学习课文之前，教师让学生思考教材第122页上方“THINK ABOUT IT”的两个问题，然后和自己的同桌讨论。
2．教师让学生浏览一遍活动1的四个句子，然后浏览文章，完成活动1的练习。教师邀请学生分享自己的答案，最后教师订正答案。
3．教师让学生仔细阅读文章，在文中画出重要知识点，随后教师进行一一讲解。
4．教师让学生理解了活动2方框中的单词的含义后，用这些单词的正确形式完成活动2的五个句子。教师邀请学生分享自己的答案并翻译这些句子，最后教师订正答案。
5．教师让学生一起朗读一遍活动2的五个句子，教师注意纠正发音有误的地方。
6．教师让学生独立完成活动3的练习，然后教师邀请三名学生分别读一读补充好答案的三段话，最后全班一起核对答案。
7．要点点拨。
(1)If we pollute the rivers and oceans，fish may get sick or even die.
【辨析】sick 与 ill
①sick adj.生病的，不舒服的。在句中既可作表语，也可作定语。例：The sick girl asked for a day's leave.那个生病的女孩请了一天的假。
②ill adj.生病的。作此意讲时，在句中只能作表语。例：He is seriously ill and unlikely to recover.他病得非常厉害，不大可能康复了。
(2)If the birds eat the sick or dead fish，they may die off.
die off意思是“相继死去；灭绝”。例：As he grew older，his relatives all died off.随着他年龄的增长，亲人相继死去了。
【拓展】die 还有很多固定搭配，在使用时要注意它们的区别：die of 死于……；因……而死，主要指疾病、衰老等自身的原因。例：He died of a heart attack.他死于心脏病发作。die from 死于……；因……而死，主要指事故等方面的外部原因。例：Many villagers die every year from snake bites.每年都有许多村民被蛇咬死。
8．学以致用。(汉译英)
(1)病人要多注意饮食。
Sick people should be careful about their diet.
(2)这株植物的叶子正在凋落。
The leaves of this plant are dying off.
设计意图：通过做相应的练习题巩固学生对所学的重难点知识的掌握，让学生了解地球上的生物是息息相关的，并体会到学英语的快乐。
