2018初一英语语法知识点总结There be结构
1. There be句型主要用以表达“某处有某人(某物),强调存在”其基本结构为“There be+某物(某人)+某地”,有时为了强调地点,也可把地点状语放在句首。
There is a book on the desk.
On the desk there is a book.
(1)肯定句:“There be+主语(某人/某物)+介词短语”
There are three people in my family. 我家有三口人。
There is a pen and two books on the desk. 书桌上有一支钢笔和两本书。
(2)否定式:“There be +not+主语+介词短语”
There isn’t a boy in the room.房间里没有一个男孩。
There aren’t any books on the desk.书桌上没有书。
注意:“There be句型”的否定式的构成和含有be动词的其他句型一样,在be后加not或no即可。
注意not和no的不同:not是副词,no为形容词,所以not a/an/any+n,相当于no+n。
There aren’t any pictures on the wall.
=There are no pictures on the wall.
There isn’t a bike behind the tree.
=There is no bike behind the tree.
