 Module 12 Save our world

Unit 2 Repeat these three words daily: reduce, reuse and recycle.

1. How green are you? 你有多环保？（教材第98页，3）

本模块的green都是表示“环保的，有利于环境的，关注环境的”。

green最常见的意思是“绿色，绿色的”

        This kind of cleaning product is green. 这种清洁产品是环保的。

        Let’s make our school a green school. 让我们打造一个绿色环保学校。

2. Do you walk or ride a bike to school？你是步行还是骑车去上学？

（1）这句是选择疑问句：提出两个或多个事物让对方选择，供选择的部分之间用or（“或者”）连接。回答不能用yes或no，根据实际作答。

        -Is your brother a teacher or a doctor? 你哥哥是老师还是医生？

-Neither. He is a driver. 都不是。他是个司机。

（2）ride a bike to...=go to...by bike骑自行车去.....

I ride a bike to school. = I go to school by bike.

【注意】“骑自行车”的动词短语里有冠词，介词短语零冠词。乘坐其他交通工具，用法一样。

ride a bike或者 take the bike

by bike

3. Do you take your own bag when shopping and not ask for a plastic bag?

购物时你带着自己的袋子而不要塑料袋吗？（教材第98页，3）

Repair them if possible.如果可能，就修理一下它们。（教材第98页，3）

（1）状语从句的省略

① when或while引导的时间状语从句的省略

when shopping 是when you are shopping从句的省略式。当从句主语与主句主语一致，且从句谓语中含be动词时，则从句中的主语+be动词一起省略。

        When (he was) playing the drum, he noticed Wendy was playing the piano.

当他敲架子鼓时，他看到温迪正在弹钢琴。

        While (I was) doing the dishes, I listened to the radio.

我洗碗的时候，会听收音机。

        When （you are）in Rome, do as the Romans do.

入乡随俗（当你在罗马时，要像罗马人那样做）。

【拓展】when doing/ while doing比较常见，已经成固定用法，有时候不拘泥于主语是否一致。

        Good posture is important when (we are) working at the computer.

当（我们）在电脑前工作时，良好的姿势很重要。

When ______ across the road, you should be careful.

1. walk       B. to walk      C. walked       D. walking

② if 条件状语从句的省略

当从句的主语是it，且谓语是be动词时，则主语it + be动词一起省略。

课文句子中的if possible “如果可能” 是if it is possible的省略形式。

        If possible, please inform me when you finish your homework.

如果可能的话，当你完成作业了，请通知我。

注意：其他种类状语从句也有省略式，初中阶段较少遇到，不再展开。

（2）ask for“请求，要求”。

常见搭配ask sb for sth “向某人要某物”

        You can ask for help if you can’t finish the task on your own.

如果你不能自已完成这项任务，你可以寻求帮助。

4. And what do you do with the bottles when they are empty? 瓶子空了时你怎样处理？

【辨析】 do with 和deal with

两者都有"处理；应对“的意思，但侧重稍有不同。

do with常与what连用，侧重对某物的利用或处置。

deal with常与how连用，强调处理问题的方式或方法等。

        I don't know what to do with the mistakes.

=I don't know how to deal with the mistakes.我不知道如何处理这些错误。

（2）throw away “扔掉；丢弃”，是“动副”结构，宾语是人称代词时，要放在动副两词中间。

        Please throw it away.请把它扔掉。

6.We all need a healthy environment, but we produce waste every day, and it is harmful to our environment.我们都需要一个健康的环境，但我们每天制造废物，这对我们的环境是有害的。

be harmful to 对…有害

近义短语：do harm to 或 be bad for。

= Playing computer games does harm to your eyes.

= Playing computer games is bad for your eyes.  玩电脑游戏对你的眼睛有害。

7. Repeat these three words daily: reduce, reuse and recycle.

每天重复说这三个词：减少、反复使用和回收利用。

re-前缀表示“重复，再次”。我们要善于用词缀法记忆单词。

①repeat [及物动词] “重说”

（2）last [动词] 持续，持久，耐用。表示“持续”时，后面可跟具体的时间。

10. It’s better to use china cups and cloth bags because they can be used many times.

12. We throw tons of rubbish away each year, and we have to make a change.

我们每年扔掉许多垃圾，我们必须做出改变。（教材第98页，3）

（1）tons of “许多；很多”， 相当于a lot of，后面接可数名词或不可数名词都行。

其中ton是名词，意为“吨”，故tons of 后面的名词常是可用“吨”来计重的东西。

        China has tons of gold.

中国有很多金子。

题组B  能力提升练

四、    阅读理解

     Some of the greatest problems we face today are the destruction（破坏）of our environment. Brown clouds, polluted water, endangered wild animals... these problems seem so huge.

     So my family does what we can. We take cloth bags to stores instead of using plastic bags. We walk where we don’t have to drive...

     But does it do any good? When I am the only one in line at the market with cloth bags, am I doing any good? Does my walking to stores make any real difference to the world?

     I recently learned something about flamingos(火烈鸟) which like to get together in groups of a thousand or more. Every year, when the time comes for migration(迁徙), a few of them first take off from the lake. But none of the others seem to notice, so the small group returns. However, the next day they try again. This time a few more fly along with them, but most of them still pay no attention, so they return again. They try for several times. Every time a few more birds join in but, since the thousands of others still take no notice, the great migration plan is once more stopped.

     Then one day something changes. The same small group of birds once again starts flying and a small number more join in just as before, then more. Finally, they all take flight and the migration really begins. What a spectacular（壮丽的）sight it must be—thousands of flamingos taking off into the sky at once!

     A few can make a difference. Even if you’re the one to take the first step, and continue trying, others will someday take notice and together we will solve even our greatest problems.

21. Where would you most probably read this passage?

A. A guidebook. B. A movie poster.

C. A personal blog(博客). D. A science magazine.

22. Why does the writer use cloth bags in stores?

A. Because he wants to do some good to the environment.

B. Because he thinks plastic bags are more expensive.

C. Because there are only cloth bags in stores.

D. Because all the people use cloth bags in stores.

23. Why does the small group of flamingos return to the lake?

A. Because they are very tired.

B. Because they can’t find food out there.

C. Because there are some dangerous animals.

D. Because the others don’t fly along with them.

24. Which of the following is TRUE according to the passage?

A. The writer and his family never walk.

B. Flamingos like to get together in groups of a thousand or more.

C. Brown clouds and polluted water are the only problems we face today.

D. Flamingos never travel to other places every year.

25. What’s the writer’s purpose of writing this article?

A. To show that the writer loves to see the migration of flamingos.

B. To tell readers to continue trying and it can make a difference.

C. To introduce a special kind of flamingo to readers.

D. To show that there’re many problems in the world.

五、首字母填空

(2021·天津市·单元测试)根据短文内容和首字母提示，在下文空格处填入适当的词使短文完整

It’s very important that we all recycle. In nature, everything is used again. For example, when an animal dies, it becomes a (26)   animal’s food. Nothing is w (27). But humans have created things like plastic bags which can’t be broken down by nature. Our rubbish kills animals and p (28) water and soil. If we c (29) making too much rubbish, the problem will only get w (30). If nature can’t reuse the rubbish, we must deal with i (31). We should clean up the rubbish we’ve made because nature can’t do it.

Recycling is a (32) a right thing to do for another reason. The Earth is r (33) in natural materials like water and trees, b  (34)  these materials are not endless. We use up our natural materials much faster than the Earth is able to reproduce them. For example, each year we cut down more than 6,000 square miles of forests. But it t (35) a new tree about 25 years to grow.

Recycling can help us save the Earth, so let’s take action right now.
