Do you think everyone enjoys their weekends?为什么不能用to enjoy?

问题描述:

Do you think everyone enjoys their weekends?
为什么不能用to enjoy?

这里的everyone enjoys their weekends 是一个宾语从句
是省略了that的

do you think (that) everyone enjoys their weekends?
省略that. that从句 后面的要是一个完整的句子,要有主谓(宾)语, 用to enjoy就没了谓语

这个句子可以还原成Do you think (that )everyone enjoys their weekends?
这里that 被省略了,它是一个宾语从句.在宾语从句中引导词that 可以省略.如果用to enjoy的话,从句的谓语就变成了 to enjoy ,而to enjoy 是不定式,它不可以做谓语.所以不能用 to enjoy.
