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。
