there is和are的区别和用法是什么?
There is 与 There are 的区别:后跟单复数不同、后跟名词不同、使用情况不同。
一、后跟单复数不同:
There is :主语是单数,be动词用is。
There are:主语是复数,be动词用are。
二、后跟名词不同:
There is :后加单数名词或不可数名词。例子,There is a book(单数名词);There is some bread(不可数名词)
There are: 加复数名词。例子,(复数名词)There are many trees.
三、根据名词的先后顺序,使用情况不同(be动词根据最靠近be动词的那个名词决定。):
There is :靠近be动词的名词为单数时,用is。例子,There is a pen and two books on the desk.(书桌上有一支钢笔和两本书。)
There are:靠近be动词的名词为复数时,用are。例子,There are two books and a pen on the desk.(书桌上有两本书和一支钢笔。)
There is/There are称为There be句型,也称为存在句型,表示事物的客观存在,There在此结构中是引导词,已经没有副词"那里"的含义
