have_havegot以及there_be的区别

have的用法：

一、Have的意思为“有”，其单数三人称形式为has.

二、句型转换

1、has：肯定句：He has a big dog.

A、在只含有have的句子中，变否定句在have前加don’t，其余不变。变疑问句在句首加Do，其余不变。

B、在只含有has的句子中，变否定句在has前加doesn’t,has变成have。变疑问句在句首加Does, has变成have。

there be 句型

一、定义

there be句型是一常见的表示“存在”的句型。该结构表示某地某处客观存在某物，是一种倒装语序，其真正的主语在there be 之后。

二、结构

There be + sth + 地点状语

There is a flower in the bottle. 瓶里有一朵花。

There is some money in the purse. 钱包里有些钱。

三、there be 句型中be动词的确定

There is a flower in the bottle. 瓶里有一朵花。

There is some money in the purse. 钱包里有些钱。

There are four apples on the desk.桌子上有四个苹果。

2.若句子中有几个并列的主语时,be的形式要与离其最近的一个主语在人称和数上保持一致。（就近原则）如:

There is a boy, a girl and two women in the house. 房子里有一个男孩,一个女孩和两个妇女。There are ten students and a teacher in the office. 办公室里有十个学生和一个教师。

3.另外,在陈述句中为了强调地点,也可将介词短语提置句首。如:

In the tree there are five birds. 树上有五只鸟。

四、There be 结构的句型转换

1、否定句

there be的否定式通常在be后加not构成(在口语中be时常与not缩写在一起)。如果句中有some,一般要变成any。如:

There are some children in the picture. →There aren't any children in the picture.

2、一般疑问句及其答语

把be提到there前,首字母大写,句末用问号即可。其肯定答语是Yes, there is / are;否定答语为No, there isn't / aren't。如:

—Are there two cats in the tree?

—Yes, there are. (No, there aren't.)
