have和has在表示“有”是同一个意思,只是在语法上有不同。have用在第一人称和第二人称中,has都用于主语是第三人称单数的情况。具体的用法一起来看看吧!

has与have的用法区别?

have 是动词原形,has 是它的第三人称单数形式。

一、have和has的区别是have用于主语是非第三人称单数,而has用于主语是第三人称单数。

例句:I want to have my own business.我想拥有自己的事业。

二、have和has 都表示“有”,但其区别为:

have 用于主语是非第三人称单数,如:I/ you/ we /they等。

has用于主语是第三人称单数, 如 she/ he / it。

例句:

1.Suits have been shaped to fit so snugly that no curve is undefined.

套服做得非常合身,没有哪条曲线不清晰。

2.I am pleased to advise you that you have been selected for interview.

很高兴地通知您,您已入选参加面试。

3.We act as though we have godlike powers to decide our own destiny.

我们表现得好像我们拥有神的力量来决定自己的命运似的。

4.There are bargains if you have the patience to sift through the dross.

如果你有耐心细心查看一下那些废物的话,便宜货还是有的。

5.Members of Congress have been lavishly wined and dined by lobbyists for years.

多年来,说客们用丰盛的酒菜款待着议员们。

三、has:基本意思是“有”,指物质上的所有、身心上的具有或构成上的含有。引申可作“享有”“容许”“招致”等解。Have:有;Has:持有。

have的用法小结

一、have作实意动词。

1.表示“有”的意思。Look, I have wings, just like you.

2.have和一些其他名词连用,表示:

(1)一种活动。

(3)发生的情况。

(4)生育。

3.和一与动词同形的名词连用,表示一个动作(have+a+由动词转化和名词)。

Are you going to have a swim./ I have a long talk with the teacher.

4.表示“吃”、“喝”. 

 I wanted to have a cup of tea and some eggs. 

5.组成复合结构即“have+宾语+宾语补足语”. 

(1)不加to的动词不定式作宾语补足语(have sb. do sth.),表示让、叫某人做某事。

The soldier had him stand with his back to his father. 

(2)现在分词作宾语补足语(have sb.(sth.)doing),表示让(使)某人做某事。

(3)过去分词作宾语补足语(have sb. (sth.)done),表示:

①使(让,请)别人作某事,表示的动作是别人做的。

二、have与to一起构成情态动词,表示“不得不”、“必须”,可用于各种时态。

三、have做助动词与动词的过去分词一起构成现在完成时和过去完成时。

 Great changes have taken place the last two years.

四、have用于“情态动词+have+过去分词”的结构,有 推测、假设之意。

翻译:可能,也许…

1.must+have+过去分词,表示对过去时间发生的动作或存在的情况的推测,一般用于肯定句。

Her father thought that she must have met a fairy.

2.can(could)+have+过去分词,表示对过去发生事情的“不肯定”,常用于否定句和疑问句。

3.should+have+过去分词,表示“某事本该早做而实际未做”,用于肯定句。

have的ing形式

have形式是"having"。

当动词“have”用作情态动词时,其-ing形式是“having”,情态动词“have”表示完成、经历或持有某种状态或行为。下面是一些例句:

She is having a great time at the party.(她在派对上玩得很开心。)

They are having dinner together.(他们正在一起吃晚餐。)

Having studied for hours, he finally understood the concept.(经过几个小时的学习,他终于理解了这个概念。)

请注意,"having"作为动词的-ing形式时,通常与助动词"be"连用,构成进行时态或完成进行时态。

have的否定形式

have是原形,否定是have not,可以缩写为haven't.例如:

I haven't seen him for a long time.

我很长时间没看到他了。

has是have的三单形式,否定是has not,缩写为hasn't.例如:

She hasn't come yet.

她还没有来。

have/has句型与there be句型的比较:

两者都表示“有”,但用法不同。前者表示所属关系,即表示“某人或某物有什么”,而后者表示存在,表示“某地有什么”。

They have some new books.

他们有一些新书。

There are some new books on their desks.

他们桌子上有一些新书。
