have的助动词用法

(1)表达完成时态

句型have (has, had)+p.p. …

句型can (could), …have + p.p.

例:He can’t have said such a foolish word.

(他不像是会说了这样傻的话。)

解说:本例句是在表达对过去的推想。

(2)“have”的惯用句式

句型had better +V…

例:You had better go and tell her everything.

(你最好去向她把事情全盘地说明白。)

解说有些文法学家把本句式的“had better”称为半助动词(Semiauxiliary verb),因为“had better”之后接原形动词,其本身所表现的功能很像是一个助动词。“had better”不可分开使用,“had”亦非过去形式。实际上“had better”所指的时间性是现在或将来,若是指过去则用“had better + have +p.p.”。本句式绝无“have/has better +V”的形式,宜注意。

本句式是用于表达建议或劝告,言外之意是“若不这样做就不好或会有不良后果”。

例:You had better take an umbrella.

(If you don’t do, it may rain and you’ll get wet.)

本句式也可用于第三人称。

例:He had better stop smoking.

(他最好把烟戒掉。)

“had better + V”的否定是把“not”置于“better”之后,例如:

例:You had bet ter not borrow money from your friend’s wife.

(你最好不要向朋友的太太借钱。)

本句式的“had”因发轻音,有时甚至轻到几乎不发音,所以也就常被省略。

例:You had better take an umbrella with you.

=You’d better take an umbrella with you.

=You better take an umbrella with you.

=Better take an umbrella with you.

(你最好带一把雨伞去吧。)

“had better”可用“had best”来加强语气。

例:We had best hurry, or we’ll miss the train.

(我们最好快一点,不然就赶不上火车了。)

本句式通常不用在疑问句,不过可以使用于附加疑问。

例:We’d better get on with the work, hadn’t we?

(我们最好把工作赶一下,怎样?)

(3)“have”表达义务

句型have/has/had to + V…

“have to + V”所表达的意思与“must + V”几乎相同,因此也有文法学家把“have to”称为半助动词。

例:I have to go to help her every Saturday.

(每星期六我得去帮她的忙。)

例:You have to take care of your sisters. It’s your duty.

(你应该照顾你的妹妹,这是你的责任。)

解说英式口语常用“have got”的表达法,实际上口语的“have got”是等于“have”,没有完成时的意思。

例:I have got to clean the blackboard before the teacher comes.

(我必须在老师来之前把黑板清理好。)

“have (got)to + V”的否定句和疑问句都使用“do”来造成。

例:Did you have to tell her everything?

(你真的必须把每一件事都向她说吗?)

例:You didn’t have to tell her, did you?

(你本来就没有必要向她说的,对不对?)

“have (got)to + V”与“must + V”的区别:这两者,英、美人通常都不很在意地随便在使用,不过在讲究的语法中通常是,表达来自说话者本身的“需要或必须”时使用“must + V”,表达非来自说话者本身的“需要或必须”时则使用“have (got)to + V”。

例:I must go to bed now; I am very tired.

(我很疲倦了,我必须上床去睡。)

例:I’ve got to go now; my wife will be waiting for me.

(我必须走了,因为我的太太会在等着我。)

助动词的用法

助动词在英语学习当中作了解,不需要重点把握,但是助动词也是很好理解的,希望回答能够帮到你。 1.助动词:Be 助动词不能作述语动词,要与本动词一起构成动词片语,表示时态、语态等。 1. BE作为本动词表示状态或客观存在等意思。 Your house is bigger and nicer than mine. 你的房子比我的又大又好。 2. BE+不定词连用,表示约定、义务、命令等未来的动作或状态。 I am to go abroad on business tomorrow. 明天我要去外国出公差。 表示未来的安排。 The meeting is to be held as scheduled. 会议将按原计划召开。 表示计划好的安排。 You are not to bark at my friend. 你不许对我的朋友叫。 表示命令或要求。 3. BE+现在分词构成各种进行时态。 Who are you talking to? 你在和谁说话? I am talking to my dog. 我在和我的狗说话。 4. BE+过去分词构成被动语态。 That means I will be promoted as scheduled. 这就意味着我将要按原计划得到提升。 2. dare和used to 作为情态助动词的dare一般只能用于疑问句或否定句中,dare+原形动词表示敢。

I dare not say it is ugly. 我不敢说它丑。 How dare you say so? 你怎么敢这么说? dare也可以作本动词,用于肯定句,后面要接带to的不定词;主词若是第三人称单数,简单现在式时,dare要变为dares。 You, you dare to talk to me like this! 你、你竟敢这样和我讲话! used to+原形动词表示过去的习惯或状态,而现在已经不存在了。 You're not what you used to be. 你不是以前的你了。 used to构成疑问句时有两种形式。即used + 主词+ to + 其他成份?;Did + 主词+ use to+ 其他成份。 How used I to be? 我以前什么样? How did you use to be? 你以前什么样? used to构成否定句时有两种形式,即used not to和didn't use to。 You didn't use to say things like this. You used not to say things like this. 你以前不会说这样的话的。 be used to表示习惯于,其中used是形容词,to是介系词,后接名词、代名词或动名词等,可用于不同的时态。 You're used to hearing words of praise. 你是听好话听惯了。 3. 助动词:Do 1. DO作为助动词时的时态、人称和数的变化与它作为本动词相同,有do, does, did三种形式。 Yes, it seems he doesn't really want to have a haircut.

谈谈have作助动词用法

谈谈have作助动词用法 have在现代英语中是用得较多的动词之一。它除了用作实义动词(ordinary verb), 表示topssess (具有),to hold (保持),to experience (经验)等意义外,还大量用作助动词。现就其助动词用法作一简述: 一、帮助构成完成时和完成进行时的各种时态。例如: 1)完成时: He has finished his task. The sun had already set before we arrived at the railway station. He shall have written the article by then. 2) 完成进行时: I have been working as an interpreter for years. He told me that he had been waiting for me even since the morning. 二、帮助构成复合谓语(和不定式动词连用)。 1) have to的用法。具有语气动词的作用,表示必须履行的义务责任(obligation), 或表示客观情况的需要,或必然性,几乎同情态动词must具有同样的意义。例如: I have to go there = I must go there. If you want to catch the first train you have to leave at six. He sees very badly, he has to wear glasses all the time. The children have to play in the streets till their mothers get home from work. In my district there is no gas laid on; people have to use electricity for every thing. be to和have to在意义上是不相同的。试比较下面两个句子: We are to finish our work at five o'clock. We have to finish our work at fine o'clock. 第一句are to finish 表示预定计划;这是大家知道的。第二句“have to finish”表示“必须在什么时候完成”,不管我们愿不愿意。 2) had to的用法。表示在过去时间里客观环境所产生的责任、任务或必然性,可用作 must的过去形式。例如: The buses were all full:I had to get a taxi. She fell ill and had to leave early. I got lost and had to ask a police man the way, When I changed my job, I bad to move to another flat. In October the expedition siled, but it had to make its way against adverse winds. 3)have to, had to常在会话中单独使用,这时不定式动词可不提及,但仍可理解。例 如: Do you have to translate the whole text into Japanese? No, you don't have to. why do you always wear dark glasses? I have to (wear them). My eyes are very sensitive. I didn't want to stop but I had to (stop) as I needed petral (汽油)。 三、have + object + past participle 结构. 1 )可更为简洁地用来表示下列类型句子的说法。例如: I employed someonce to do something for me.

He does his homework in the evening. 2.作为助动词,也就是帮助主要动词构成否定和疑问等。 We don't like bananas. Do you like apples? Does he like English? He doesn't like swimming 上面有一句He does his homework in the evening.要是变成否定句就成了这个样子: He doesn't do his homework in the evening. 这里加上了助动词doesn't,而原来的主动词does变成原形do了。 作为助动词的do和does是没有词义的,它们在句中的构成一般现在时的疑问句和否定句.

Have与 has的用法及区别

Have与has的用法及区别 have与has都是“有”的意思,但二者用法是有区别的. 在陈述句中,当主语是单数第三人称(he、she、it)时,句子的谓语是“有”时,用has;当主语是其他人称(I、you、we、they)时,句子的谓语是“有”时,用have. 例句: I \ You have an apple . We\They have some apples . He\She has a pen . 但是,在疑问句中,当主语是就单数第三人称提问或否定句时用助动词does 和does not (doesn't),然后把has 变成have 如果不是第三人称,助动词就是do ,否定式do not (don't).特殊疑问句回答照样,该是has 还是has 该是have 还是have 但是当一般疑问句以do或does开头的时候,只能回答do don’t 或者does doesn't 例句: Do you have a book yes ,I do /No ,I don't What does a cat have the cat has a , He doesn’t have any coffee. 就是第二种:have本身也可以作为助动词,(作为完成时里的助动词)本身无词义,和do 一样,has 就相当于does 在单三情况下用,主要用于构成各种时态、语态、语气以及否定和疑问结构.(那此时的have还是has就要看具体的人称而定)完成时态是have/had + done (过去分词的形式) I have finished my work, she has finished her work have you finished your work? Has she finished her work?在一般疑问句里回答直接用have/has yes,I have/ No ,I haven't Yes,she has/ No,she hasn't(因为这里have/has是助动词)
