2018小升初英语知识点:There be句型
【There be句型】
(1)There be 句型主要用以表达“某处(某时)有某人(某物)。”其基本结构为“There be+某物(某人)+某地(某时)”其中there是引导词,没有词义;主 语是be后面的名词, be是谓语动词,在一般现在时中be只用is和are两种形式。下面这首歌诀可帮你巧记there be句型结构:
There be放句首,主语跟在后。地、时放句末,强调置前头。如:There is a book on the desk.有时为了强调地点,也可把介词短语放在句首。
如:On the desk there is a book.
(2)There be 句型中的be动词如何确定呢?请先看看下面这首歌诀:Be动词,有三个,am,is还有are。“There be”真特别,不留am只留俩,那就是is 还有are。要用is还是are,须看其后的名词是单数还是复数。若是单数或不可数名词用is,否则就用are。
如:①There is a tree behind the house.
②There is some water(水)in the bottle(瓶子).
③There are some pears in the box.
(3) 注意:如果“be”后的主语是由and连接的两个或两个以上的名词,那么be的形式要遵循“远亲不如近邻”的原则。也就是说,“be”的形式是由与它最近 的那个名词来确定的。若那个名词是单数或不可数名词要用is,是复数就用are。
如:①There is a book and some pens on the floor.②There are some pens and a book on the floor.
