thErE is ArE的用法

there is,最近的主语是第三人称单数there are 最近的主语是复数如There is a book ,two pens and three pencils in the bag .There are two books ,a pen and three pencils in the bag.

一、构成:There be 句型表示的是 “某处有(存在)某人或某物”,其结构为There be(is,are,was,were )+名词+地点状语.例如:There are fifty-two students in our class.

There is后面加单数名词或不可数名词 例如:There is a bird in the tree.树上有一只鸟.There is some milk in the bottle.瓶子里有一些牛奶.There are 后面加可数名词复数形式 例如:There are many students on the playground.操场上有许多学生.再比如:There is a bird singing in the tree.There be +doing.的结构

there is意思为(那是),是单数,is后面只能加定冠词a或an,意思为那是一个…… there are 意思也是(那是),是复数形式,后面加(too many)(too much)(some)等词语,意思是那是一些……

there is a book , a ruler and 2 pens.这里是就近原则.后面紧跟的是a book所以用is 若紧跟的是2 pens用are

用法区别:There is+可数名词单数/不可数名词+其它 There are+可数名词复数+其它

some有“某”的意思,有“一些”的意思,前者为单数,后者为复数.还有一种情况,是some通用单复数,它是个特别的词.

there is后面加单数名词,there is my 老豆 my 老母正确,如果你有一个哥哥姐姐那么there is my阿哥 my 姐姐也正确 there are后面加复数名词,如果有一个以上的哥哥姐姐,那么就用there are my 哥哥姐姐

用si 因为“BOOK”是单数用are的时候是要有复数的比如“BOOKS”

"There be"是英语中最常见的又是非常重要的句型,它是表示"存在" 的一种基本方式,其句型结构通常为:There be + sb./sth. + somewhere/doing sth.但作为英语教师,仅仅知道这点用法还远远不够,"There be"还有更多较为特殊的用法
