some children are interested in playing computer games为什么还加are

问题描述:

some children are interested in playing computer games为什么还加are

1. be interested in 是固定搭配啊
2. 主谓宾的结构啊 ,some children 主语啊

这是一个固定短语 意思是对......感兴趣
be interested in sth./doing sth.
然后这里的主语是Some children
所以用复数are
希望能帮助你~

are interested in
be interested in 对……感兴趣
后面加名词或动名词.
