其基本结构为 “ There be+某物(某人)+某地(某时)主语是 be 后面的名词, be 是谓语动词,在一般现在时中”其中 bethere 只用is是引导词,没有词义;和 are 两种形式There be 句型中的Be 动词,有三个,be 动词如何确定呢?请先看看下面这首歌诀: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).③ There 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:① There is a book and some pens on the floor.② There are some pens and a book on the floor.肯定句: there is an apple on the table否定句: there isn't an apple on the table.一般疑问句 : Is there an apple on the table?回答:yes, there is. / No, there isn't特殊疑问句: what is there on the table.1. 定义: There be 句型表示某处存在某物或某人。
2. 结构:(1) There is + 单数可数名词 / 不可数名词 + 地点状语 .(2) There are + 复数名词 +地点状语 .there 是引导词,在句中不充当任何成分,翻译时也不必译出句子的主语是某人或某物,谓语动词 be 要与主语 (某人或某物) 的数保持一致。
