老师，there be 在什么情况下可以和 have进行互换？

"there be"与"have"译成汉语时都有一个"有"字，这二者之间又有什么区别呢？且看下面的比较。

解答如下：

(1)there be表示"有"时，侧重于客观存在有，常用于"某地(某时)有某物"的句型，至于此物属于谁则无关紧要。

Is there anyone in the next room？

隔壁房子有人吗？

There are five pencils in the pencil-box.

铅笔盒中有五支铅笔。

(2)have(has)表示"有"时，侧重于主观方面拥有，有"所有"的意思，常用于"某人(某物)有某物"的句型，至于此物在何时何地则无需谈及。

My grandfather has a pet dog.我爷爷有只宠物狗。

Do you have a watch？你有手表吗？

A:当have/has包含存在有情况下there be和have(has)可以互换使用，句子意义没有什么差别。

A week has seven days.

=There are seven days in a week.

A year has three hundred and sixty-five days.

=There are three hundred and sixty-five days in a year.

We have a lot of time. 

＝There is a lot of time.我们时间很多。

The classroom has ten desks.

 = There are ten desks in the classroom. 

教室里有十张桌子。　

B:当have/has不包含存在有情况下，there be和have是不能互换使用的。

I have two hands.我有两只手。

不能说：There are two hands on my body.
