小学英语语法:There_be_句型

发布时间:2013-11-05 13:42:00  

小学英语语法

1. There be 句型表示 “有”/ “某地有某物”
There be + 某物/某人 + 某地/某时
(主语) (状语)

2. there be 句型与 have的区别:
1)there be 表示在某地有某物(或人)。 如: There is a table in the room.房间里有一张桌子。 2)have 表示某人拥有某物。 如:I have a table.我有一张桌子。

There is a cat under the tree.

There are two dogs under the tree.

There is a cat under the tree.

There are two dogs under the tree.

There is a cat and two dogs under the tree. There are two dogs and a cat under the tree.

3 就近原则 There be 句型中be 动词单复数的变化
若be动词后面的词是单数名词,be动词用is

反之若为复数名词,be动词用are

若主语为不可数名词,be动词用is
There is some bread on the table.

4. There be 句型的否定形式:
只要在 be 动词后面加 not 即可,但要注意的是句 中的some 改成 any.
some用于肯定句,any用于否定句或疑问句 且 not any 与 no 可以互换 。

1)There is a knife in the kitchen. 否定:There is not a knife in the kitchen.
2)There are five apples on the tree. 否定:There are not five apples on the tree. 3)There is some ink(墨汁) in the bottle. 否定:There is not any ink in the bottle. =There is no ink in the bottle. 4)There are some books in the bag. 否定: There are not any books in the bag. =There are no books in the bag.

6. there be...句型 的一般疑问句
把 Be动词放在 there 之前,并将句号变问号。 (句中出现的 some 要改成 any) 肯定回答为:Yes, there is/are. 否定回答为: No, there isn’t/aren’t.

1)There are five pens on the desk. Are there five pens on the desk? Yes, there are. / No, there aren’t.
2) There is some water in the cup. Is there any water in the cup? Yes, there is. / No, there isn’t.

be有特点,主语放在be后面, ? 单数主语用is,复数主语要用are。 ? 变否定很简单, be 后要把not添。 ? 变疑问也不难, 把be提到there前。 ? 否定疑问any换,就近原则多多练。
? There
