小朋友们,大家都认识there is 吧,它是“某地有某物”的意思,它是个小瘦子,后面只能跟单数名词。看:
There is an apple on the desk.书桌上有一个苹果。
它有个小哥哥 there are,它可是个小胖子,愿意交朋友,它一出场,后面的单数名词就变成复数了。如:
There are two apples on the desk.书桌上有两个苹果。
There are some bikes under the tree.树下有几辆自行车。
和小弟弟there is脾气一样,there are构成句子时,也爱站在句首,后面直接跟复数名词。
对了,两人还经常合作呢,但是“一山不容二虎”。在后面又有单数名词,又有复数名词时,兄弟二人只有一人出现,两人还商量好,离be最近的是单数名词时,弟弟there is上;是复数名词时,哥哥there are上。如:
There is a pen and two pencils in the pencil-box.
There are two pencils and a pen in the pencil-box.
怎么样,它们兄弟二人很厉害吧!
