答案
C
解析

试题分析:考查状语从句:考生容易认为是在考查强调句。It be+被强调部分+that/who+其余部分。而判断一个句子是否为强调句型,只需将其中的It is/was和who/that去掉,如果句子结构完整通顺,则是强调句型,否则就可能是其他语法形式。如果选C项,去掉It was和所填的that后,时间状语前缺少介词,句法错误,因此该句不是强调句型,而是状语从句。其次,认为是在考查it…before…句型。It is+时间段+before句型的肯定式表示“过多久……才、就”;否定式表示“不久……才、就”。此题如用before逻辑不符,这题是when引导的时间状语从句,it指时间,句意为:-Jack昨晚回来得很早吗?-是啊,当他到家时还不到8点。故答案选C。
