英语,基础语法,为什么不选A
楼主既然你已明白答案是when,它引导时间状语从句.这个就不用再解释了.
即：It was ten o'clock when he came back. 时间状语从句
如果用A答案,即 It……that 则是强调句型,但这此题还不满足条件,要作修改,如下：
It was at ten o'clock that he came back. 强调句,强调时间状语at ten o'clock,原句没有介词at.
对应原一般陈述句: He came back at ten o'clock.
即：It was ten o'clock when he came back. 时间状语从句
如果用A答案,即 It……that 则是强调句型,但这此题还不满足条件,要作修改,如下：
It was at ten o'clock that he came back. 强调句,强调时间状语at ten o'clock,原句没有介词at.
对应原一般陈述句: He came back at ten o'clock.
