题目内容：

Many people who have been to the park _____（返回）with their friends.

优质解答

return
因为前面用了现在完成时have been,所以return用一般现在时.

追问：

have been 后面不是加doing或done的么、

追答：

课本里常用的一个表达方式，Have you ever been to......你有没有去过什么地方。 说去过哪里时用have been to就行，不用额外加动词。

追问：

可是return是动词、

追答：

Many people who have been to the park _____（返回）with their friends. 很多人 去过这个公园的 都是和他们的朋友们一起回来的 who have been to the park 就从句。 主干是Many people return with their friends. 所以return和who have been to the park是相互独立的。
