问题描述:

do you work in the lab every afternoon----no ,but sometimes,i wish i had time to.
为什么回答不可用,i wish i had time to do,
还有do可以指代什么,可指一件事吗

i wish i had time to 是省略句型,完整的回答是i wish i had time to work in the lab every afternoondo 可以指work in the lab every afternoon 这样一整件事吗不能,你要是想用do,可以用it代替,i wish i had time to do it
