3. 语言知识点的归纳整理。
（1）We’re trying to save the earth! 我们正在竭尽全力拯救地球!
try to do =try one’s best to do 努力去做某事。
? Every student should try to study hard in order to study in a university. 为了进入大学学习，每个学生都应该努力学习。
（2）Everyone in this town should play a part in cleaning it up!
play a part in 在……方面起作用
? A good diet plays a large part in helping people live longer. 健康的饮食在帮助人们长寿方面起着非常大的作用。
（3）used to…
① used to的意思是“过去经常”，其中的to是不定式符号，不是介词，所以其后接动词原形(不接动名词)。
? He used to live in Paris.?他过去一直住在巴黎。
② used to?与?be used to的用法比较
·used to?意为“过去经常”，其中的?to?是不定式符号，后接动词原形。
? He used to live in Paris.?他过去一直住在巴黎。
·be used to?意为“习惯于”，其中的to是介词，后接动名词。
? He is used to living in the country.?他已习惯于住在乡下。
（4）should的用法：should后接动词原形。

②表示“可能，该(=will probably) ”
? He should arrive soon他可能很快就到了。
③ should与ought to的比较
· 除表示“万一”“竟然”等只能用should外，表示“应该，应当”“可能”等，两者可互换，只是ought to的语气稍重。
? You ought to/should work harder than that. 你应当更努力地工作。
· should 强调主观看法，而 ought to 强调客观要求。
? We ought to go and see my mother in hospital tomorrow, but I don’t think we will. 我们按理应当在明天去看看住院的母亲的，但我主认为我们不会去。

B: I agree. it's good for the environment.
3. 语言知识点的归纳整理。 现在进行时
（1）含义：表示正在发生或进行的动作。
（2）基本结构：
主语 + be + 现在分词（be 的形式随主语的变化而变化）
（3）基本用法：
①表示现在正在进行的动作。特征：常常与now或具体的时间连用，有时句中会有感官动词来提示，或通过上下文来暗示。
②表示现阶段一直进行的动作。这类动词常常是延续性动词。常于at present, this week, these days等连用。
③表示主语的特征、性格、能力等
现在完成时
（1）含义：表示过去发生的动作对现在还有影响。
（2）基本结构：主语 + have / has + 过去分词
（3）基本用法：
①表示过去发生的动作，但强调对现在产生影响。特征：不能与表示具体的时间状语连用。
②表示过去发生的动作或存在的状态一直延续到现在，还可能继续下去。常常与since, for, in the past + 时间名词，in the last +时间名词等时间状语连用，而且谓语动词要求是延续性动词。
③表示一种“经历或体验”，即可以表示经历过也可以是从来都没有经历过。
被动语态
初中阶段我们学习了七种被动结构，归纳如下：
（1）一般现在时是被动语态：am / is / are + 过去分词
（2）现在完成时的被动式：
have / has + been + 过去分词
（3）现在进行时的被动式：
am/ is/ are + being + 过去分词
（4）一般过去时的被动式：was / were + 过去分词
（5）过去进行时的被动式：
was / were + being + 过去分词
（6）过去完成时的被动式：had + been + 过去分词
（7）一般将来时的被动式：
will / be going to be+ 过去分词
（8）含有情态动词的被动式：
情态动词+be +动词的过去分词。
情态动词
情态动词表示说话人对某一动作或状态的态度，如认为“可能”、“应当”、“必要”等。情态动词本身有一定的意义，但不能单独作谓语，也没有人称和数的变化。后面一般跟动词原形。
used to 结构
used to意为“过去常常做某事”，指的是过去的习惯性动作，目的在于与现在形成对照。used to是个情态动词，其中的to是不定式符号，后面跟动词原形。在美式英语中。它的疑问式是：Did ＋主语＋use to do sth．？否定式是：主语＋didn't use．．。在英式英语中，它的疑问式应当是：Used ＋主语＋to sth．？否定式应当是used not to或use（d）n't to。
He used to stay up late. 他过去常熬到很晚。

bring back 恢复；使想起；归还
not only ... but (also) ... 表示“不但……而且……”。本句中的not only位于句首，其后的主谓要部分倒装，即根据主语的人称和数以及时态的变化，将不同的助动词提到主语前，需要注意的是but (also)后面的主谓不用倒装。
? Not only did my aunt teach at school, but (also) she wrote articles for newspapers.
我阿姨不仅在学校教书而且还给报纸写稿。

Write a letter to the city mayor about the problems and your suggestions.
Dear Sir/ Madam,
Environmental problems are becoming more and more serious all over the world.
With the development of the society, there are too many cars on the streets in our city. Cars have made the air unhealthy for people to breathe. Black smoke and poisonous gas are given off by factories. Factories also put waste into the river. And wherever we go, we can find rubbish.
Now more and more people have realized these problems. I think that governments should close down the factories and develop laws to stop people from driving cars every day. I suggest everyone in this town should help to clean up the river and the streets. We should call on everyone in the town to throw rubbish in the dustbins.
I hope the problem will be solved in the near future and our home will become better and better.

写作一封书信，信中首先要介绍你所在城市存在有哪些环境问题，是谁造成的这些问题，然后提出解决这些环境问题的方法和措施。
Dear Mr. Mayor, Thanks for making some time to read this letter. I’m a native here. I think everyone in this city wants to have a bright and beautiful home. But there are some environmental problems in our city. The river used to be very clean, but now the river was dirty. Even the bottom of the river was full of rubbish. People are littering in the river, Factories are pouring rubbish into the river. The air has become really polluted around here. There are so many cars on the road these days. More and more people driving to work or school today. Factories that burn coal also pollute the air with a lot of black smoke. There is also too much rubbish and waste around our living places. People throw away rubbish like waste plastic in public places. This turns beautiful places into ugly places.
To cut down environmental pollution, I think we should develop laws to stop factories’ littering. We should take the bus or subway instead of driving. Never take wooden chopsticks or plastic forks when buying takeaway food, remember to throw rubbish in the cans and keep public places clean and beautiful for everyone. I suggest that everyone in this town should play a part in improving the environment. I believe that our actions can make a difference and lead to a better future!
Best wishes,
John
