题目内容：

A great many people,when they speak of home,tend to associate it with a certain atmosphere,
这句中,tend为何能够直接用原形?不是应该用tending吗?

优质解答

这句话里tend是谓语动词,根据句意是很多人,当然用原形.
when they speak of home 只是插入的状语,你可以把它调到句尾,A great many people tend to associate it with a certain atmosphere when they speak of home,这样就好懂了
