行为动词
一、行为动词
1.行为动词是实义动词,有完整的词义,能独立做谓语。
(1)及物动词:后面能直接跟宾语,通常可以用于被动语态。

情态动词
三、情态动词
情态动词是表示说话人对某一动作或状态的观点或态度的动词,它们本身具有一定的词义,但通常不能独立作谓语,而是与动词原形一起构成谓语。
常用的情态动词有can, could, may, might, must, have to, will, would, shall, should, need, dare等。
1. can, could 的用法
1) 表示能力、技能。
She can swim fast, but I can’t.
Can you swim
2) 表示请求和允许。
---Can I go now
---Yes, you can. ( No, you can’t.)
3) 表示推测,意为“可能”,常用与否定句和疑问句中,此时can’t意为“不可能”。
Can the news be true
This can’t be done by him.
4) 在疑问句中,此时could并不是can的过去式,只是表示委婉的语气。
--- Could you do me a favor
--- Yes, I can. ( No, I’m afraid not.)
5) 表示客观可能性(客观原因形成的能力)。
They’ve changed the timetable, so we can go by bus instead.
This hall can hold 500 people at least.
2. may, might的用法
1) 表请求和允许,might比may语气更委婉,而不是过去式。
You may take whatever you like.
--- May (Might) I smoke here
--- Yes, you can. (No, you can’t/ mustn’t.)
2) 表示推测可能(不用于疑问句),might不是过去式,它所表示的可能性比may小。
He may/ might be busy now.
Your mother may /might not know the truth.
3.must, have to的用法
1) 两词都表示“必须、必要”的意思。have to强调客观需要,must是说话人主观的看法。
My brother was very ill, so I had to call the doctor in the middle of the night.
--- Must we hand in our homework today
---Yes, you must. ( No, you don’t have to/ you needn’t.)
2) have to有人称、数、时态的变化,而must只有一种形式。
He had to look after his sister at home yesterday.
3) 表示推测、可能性(只用于肯定的陈述句)
You’re Tom’s good friend, so you must know what he likes best.
Your mother must be waiting for you now.
4. will, would的用法
1) 表示“将、将要、自愿做……”等。
People will die without air or water.
2) will表示请求、建议等,would更委婉。
Will/Would you please pass me the ball, please
Would you like to go with me
5. shall, should的用法
1) shall的用法
(1) 用于第一、第三人称的疑问句中,表示说话人征求对方的意见或请求。
Shall Tom go there with me tomorrow
Shall I wear the evening dress for your party
(2) 用于第二、第三人称,表示说话人给对方的许诺、命令、警告或威胁。
You shall get an answer from me tomorrow.
2) should的用法
(1) 用来提供帮助、提出建议,要求对方给出意见。
Should I help you with the community affairs
(2) 表达义务、职责等。
I think today’s children should really learn to respect their elders.
6. need, dare的用法
1) need 作情态动词用时, 常用于疑问句、否定句。在肯定句中一般用must, have to, ought to, should代替。
You needn’t come so early.
--- Need I finish the work today
--- Yes, you must. (No, you needn’t.)
2) dare作情态动词用时, 常用于疑问句、否定句和条件从句中, 过去式形式为dared。
How dare you say I’m unfair
He daren’t speak English before such a crowd, dare he
3) dare和 need作实义动词用时,有人称、时态和数的变化。在肯定句中,dare后面常接带to的不定式。在疑问句和否定句中,dare后面可接带to或不带to的不定式。而need后面只能接带to的不定式。
I dare to swim across this river.
He doesn’t dare (to) answer.
He needs to finish his homework today.
4) need后面接doing表示被动:need doing = need to be done.
The washing machine needs repairing. = The washing machine needs to be repaired.
7. had better的用法表示“最好”,相当于一个助动词,只有一种形式,后面要跟动词原形had better (not) do sth.
It is pretty cold. You’d better put on my coat.
(You’d better =You had better)
易错点:
1.can和be able to两者表示能力时用法相同,但can只有原形和过去式两种形式,在其他时态中要用be able to来表示。另外be able to常常指经过努力,花费了时间和劳力之后才能做到某事。
Jim can’t speak English.
I’m sure you’ll be able to finish it quickly.
2.“May I … ”表示请求许可时,否定回答要用mustn’t或can’t,而不能用may not。
---May I go now
---Yes, you may/ can. / No, you mustn’t/ can’t.
易错点:
3. 对must 引导的一般疑问句,肯定回答用must;否定回答用needn’t/ don’t have to.而不能用mustn’t. 因为mustn’t表“禁止”之意。---Must I clean the dining room at once
---Yes, you must. / No, you don’t have to. / needn’t.
4. need 做情态动词,意思为“需要、必须”,通常用于否定句中。You needn’t do all these exercises.

助动词
四、助动词
助动词本身无意义或意义不完整,只是帮助实义动词完成某些语法功能,它不能单独作谓语。必须和其他动词连用,构成各种时态、语态、否定句和疑问句等结构。
1. Be 动词 be (is, am, are, was, were, being, been)
2. 情态动词 Can/could will/would shall/should
3. 狭义助动词 do (does, did)
4. 完成助动词 have (has, had, having)
1.be 动词做助动词
eg: I am looking at you. 我正在看着你。
I am a teacher. 我是一个老师。
2.情态动词做助动词
①不能单独构成为谓语
She can dance.
(can辅助dance 成为谓语,主语发出的具体的动作是dance跳舞)
②后加动词原形
She can dance.(dance 是动词原形)
(助动词)
(系动词)
③无人称变化
I can swim.
He can swim.
④有本身的含义
can 可以表“能力,可以” / will表“将会”,need表“需要”/must表“必须”
You must eat regularly.
3.狭义助动词:do does did
①用do表强调
eg:Do be careful with that fire.
I do hope you pass the exam.
②用does表强调
eg: He does look very handsome.
③用did表示强调
eg:She did write a letter to you.
4.完成助动词: have has had
①由助动词have 构成现在完成时(现在完成时的结构:have/has + done)
eg: I have read a book these days.
(主语具体发出的动作是read,have 是起辅助作用,帮助read 构成完成状态)
I have a million dollars.(此时have 是实义动词,表示“有”)
②由助动词has构成现在完成时
eg: Tom has taught in this school for ten years.
(主语具体发出的动是taught(taught是teach的过去分词),has是 起辅助作用,帮助taught构成完成状态)
③由助动词had构成过去完成时(过去完成时的结构:had + done)
eg: They had visited a doctor.
(主语具体发出的动作是visted, had 是起辅助作用, 帮助visited 构成完成状态)
有时候为了避免动词的重复,使语言更加简练,常用助动词do的某种形式来代替前面出现的行为动词。
He works even harder than you do.
(do代替work)
=He works even harder than you work.
1.If it is fine tomorrow, we ______ a football match.
A. have B. will have C. has D. shall has
