6. had better

1.can和coul d

① can表示能力,意为“能够,可以”,could用于过去时,

例如He can finish his homework al one. 他可以单独完成作业的。

He couldn’t cook when he was 18 years old. 他18岁时还不会做饭。

② can表示推测,意为“可能”,在否定句中表示否定的猜测,意为“不可能”,could用于对过去的猜测,can’t be 不可能

例如:He could be cooking at this time yesterday. 他昨天这个时候有可能正在做饭。

③ can表示请求语气,coul d的语气更委婉,

例如:Can I help you? / Coul d I help you? 有什么我可以为您效吗?

拓展:be abl e to=can也为“能够”,用来表示能力(有人称和时态的变化)

例如:He is able to d eal with this problem. 他能解决这个问题的。

2.may和 might

① may表示请求,might语气更委婉,

例如:May I help you?

Might I sit here?

② may表示肯定的推测,语气比can更弱,might对过去的推测

例如:Mary may be doing her homework now.

May can be doing her homework now. can表达的推测语气比may更强,更有把握。

3. must和have to

①must表示命令、责任,意为“一定,必须”,must not/ mustn’t表禁止,“一定不要”,

例如:Children must stay away from strangers.孩子一定要远离陌生人。

刘老师现在肯定在度假因为他正穿着平底裤呢!(上课是要穿正装的)

③ Must作一般疑问句开头提问时:肯定用must回答,否定用needn’t或d on’t have to回答。

例如:Must I finish my homework now?

Yes, you must. / No, you ne edn’t.

④ must 和have to 的区别:

a) must没有人称、时态的变化,而have to根据人称、时态的变化,有不同的形式。

b) Must表示主观上必须做,而have to 表示客观需要。

例如: I must go now. 我必须走了。(我想走了)

I have to go now. 我不得不走了。(因为太晚了等原因,不得不走)

◆Need的用法:

Need既可以作“情态动词”,又可以作“实义动词”。

① Need作“情态动词”的用法:肯定:need 否定:needn’t.

a) need 作“情态动词” 时,多用于否定句和疑问句中,一般不用于肯定句。例如: You needn’t worry about us.

Need I water these fl owers now?

b) 作一般疑问句开头提问时:肯定用must回答,否定用needn’t回答。例如: Need I clean the room?

Yes, you must. / No, you needn’t.

② Need作“实义动词”的用法:

a)Need作“实义动词”时,可接名词或动词不定式。

肯定: need+名词 need+to d o 否定:d on’t need to d o

例如: I need some water, I am very thirsty.

肯定: I need to study hard.

否定:You don’t need to clean this room.

b) 疑问句式:要借助助动词 do /does.

例如: Does she need to do her homework now?

3.shoul d, ought to

① should表示义务,意为“应该”。否定:shouldn’t 表示“不应该”。

②ought to表示义务,意为“应该”,语气更强。否定:ought not to表示“不应该”.例如:We should protect our environment.我们应该保护我们的环境。

We ought to protect our environment.我们应该保护我们的环境。

4.shall, will和woul d

① shall 表请求、建议,

例如:Shall we go shopping together?

② will表请求、意愿,woul d表对过去的意愿或者比will语气更委婉的请求

例如:I will not make this mistake again. 我不会再犯这样的错误了。

Will you open the d oor? 你可以打开下窗户吗?

Woul d you like a hamburger? 需要来一份汉堡吗?

5.had better 表“最好”,

例如:You had better take a taxi or you will be late.

◆注意:

①情态动词没有单复数形式变化,除了have to

例如:They have to face their problems.

②情态动词变为否定句直接在其后加not,回答时用相应的情态动词帮助回答,

例如:Can I help you?

Yes, of course. / I can. No, I can’t. (注意要用缩写形式回答,但may和might除外)

I can’t / cannot/ can not help you.

但是must的一般疑问句的否定回答例外,

例如:Must I finish my homework?

Yes, you must. No, you needn’t./ don’t have to.

③ have to 的否定形式用d o/d oes/did来完成。

例如:We don’t have to go there.

The boy didn’t have to go to school because there were no peopl e there yesterday.

④need作为实义动词,其否定形式和疑问句要用助动词do、d oes或did来帮助提问,

例如:I don’t need to get up e arly.

Parents need l ove their children more.

⑤ had better否定形式在better后加not,had通常可以和主语缩写。

例如:You'd better not make a mistake again.

语法精讲

第一章连系动词

一、定义

连系动词也称系动词,它虽有词义,但不完整,所以不能单独作谓语,必须跟表语一起构成合成谓语,例如:

We are in Grad e six this year.

二、分类

连系动词可具体分为三类:

1、表示“是”的动词be。这个词在不同的主语后面和不同的时态中有不同的形式,is,am,are,was,were,have/has been等要特别予以注意。

例如: He is a teacher. He was a soldier two years ago.

2、表示“感觉”的词,即感官动词,如l ook(看起来),feel(觉得,摸起来),smell(闻起来),sound(听起来),taste(尝起来)等感官动词后面加形容词。

3、表示“变”、“变成”的意思的词,如come,become, get, grow, turn, go 都解释为“变”、“变得”

例如:

① She becomes a coll ege stud ent.

② His face turns white.

③ The weather gets warmer and the days get longer when spring comes.

4、sound弄响,发音;听起来

① The letter “h” in hour is not sounded.

7、grow生长,种植;变

home.__________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ ______________

【答案】Last Monday Wang Qiang rode his bike back home. On his way home, at a crossroads he saw an old lady going across the road. Because the traffic lig hts didn’t work at that time, all the traffic crossed the road without stopping one by one. The lady hesitated in whether she should cross it, but she was afraid to do that When Wang Qiang saw that, he offered to stop the traffic with his bike in order to lead her to cross the road safely.

In my opinion, Wang Qiang is such a good example that we should learn from him. At the same time we also suggest that all the drivers should let people cross first and then traffic when this situation happens.

【解析】

? What activities will you have in the club?

【答案】Dear Mr. Lee,

I’m writing to apply for starting a Chinese Culture Club.

As we know, more and more people are interested in Chinese culture, so a Chinese Culture Club can be a good chance for our students to learn more. In this club, students will work together to complete different projects. As a result, we can understand each other better and develop friendships.

We will have a variety of activities for students to experience Chinese culture, such as performing Beijing Opera, practising Chinese calligraphy, having paper-cutting competitions and so on. Moreover, we’ll hold some salons for students to share their life experiences in China and America. I believe everyone in the club will benefit a lot.

I hope this application will be approved. Thank you for your consideration.

【解析】

【详解】

这是一篇材料作文,根据材料中的相关信息介绍一下中华文化。所提供的材料中列举了你打算向学校申请建立一个社团( Chinese Culture Club)。主要从建立该社团的原因及社团的主要活动安排这几个方面去介绍。时态为一般将来时,人称为第一人称。注意作文中必须包含材料和提示词的所有信息,并适当发挥。写作时,避免使用汉语式的英语,尽量使用我们熟悉的句子或短语。语法要正确,表达要符合英语习惯,注意时态、时间状语的搭配及主谓一致问题。写作中适当使用连词,注意上下文联系紧密,符合逻辑关系,表达具有条理性。

Once, I couldn't make good use of time and it had a bad influence on my

study.__________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ ________________________________

【答案】Once, I couldn't make good use of time and it had a bad influence on my study.

I had an experience like this. Last weekend, my good friend, Jim taught me how to play a kind of computer game. It was interesting. So I spent more time on it. I forgot to do my homework in the end. My teachers and parents were angry with me. I was also upset.

How to make good use of our time? I think we should make a weekday plan. We should write what we are going to do on the paper, mark the deadline of each thing clearly and put the paper up somewhere we can see it easily. It can help us to remember what we have to do next.

【解析】

【详解】

这篇短文使用了大量的固定句式和短语,为文章增色不少,如make good use of,last weekend,how to do,play a game,a kind of,spent more time on,forget to do,in the end,be angry with,be going to do,on the paper,put up等。而特殊非谓语动词结构Jim taught me how to play a kind of computer game.和I think we should make a weekday plan. /We should write what we are going to do on the paper, mark the deadline of each thing clearly and put the paper up somewhere we can see it easily. /It can help us to remember what we have to do next.等复杂从句结构的运用,丰富了短文内容,使表达多样化,是本文的亮点。在学习中注意总结牢记一些固定句式及短语,写作时就可以适当引用,使文章表达更有逻辑性,也更富有条理。

【点睛】

书面表达题既不是汉译英,也不是可任意发挥的作文。它要求将所规定的材料内容经整理后展开思维,考查运用所学英语知识准确表达意思的能力。所以,考生不能遗漏要点,要尽量使用自己熟悉的单词、短语和句式,尽可能使用高级词汇和较复杂的句式结构以便得到较高的分数。

Low-carbon life is a kind of lifestyle. It’s a habit to save all the sources of energy around us. It’s important to protect our environment. First, I always go to school on foot and tell my parents to walk to work instead of driving the car. Second, I save water and electricity by turning off the taps , fans; TV sets and lights in time when I don't need them. What's more, water is reused by us in my family all the time. Third, I use the both sides of the paper. I think it is good to make full use of paper. By doing this, we can save many trees. At last, I would go shopping with basket rather than plastic bags.

I believe our life will become better and better if we can do these things.

Lower carbon, happier life. Let's take actions.

1助动词和情态动词的定义 在英语中,助动词一般没有词义,主要帮助构成谓语,表示时态、语态或构成疑问及否定形式。对于助动词,同学们一般了解即可。 情态动词与助动词不同,它有词义,但它也和助动词一样,不能单独作谓语,它必须和其他动词一起构成谓语,另外重要的一点是情态动词没有人称和数的变化;情态动词后必须跟动词原形。 (×)She cans swim well. (×)She can swims well. (○)She can swim well. (○)She swims well. 即使主语是第三人称单数(例如she)can也不能加“s”。 句子中有情态动词can时,即使主语是第三人称单数,也不能在一般动词(例如swim)上加“s”。 1 助动词的种类 1.be(am,are,is,was,were,been,being) 它与现在分词结合,可以构成进行时态(参见第九章),与过去分词结合可以构成被动语态(参见第十三章)。 I am reading the book.我正在读这本书。 The book was written by me. 这本书是我写的。 2. have(has,had,having) 它与过去分词结合,构成完成时态(参见第十一章)。 I have finished my homework. 我已经写完作业了。 3.shall(should),will(would)
