一.真题重现
1．【教材原句】It seemed as if the world was at an end.(U4P26) →【真题呈现】Jack wasn't saying anything, but the teacher smiled at him ______ he had done something very clever.
A．as if B．in case C．while D．thought
【要点解析】本题考查状语从句的引导词。句意：杰克什么也没说，但是老师朝他笑着，就好像他做了非常聪明的事情。as if“好像”；in case“以防万一”；while“当……时候，而，却”；though“尽管”。由句意可知A为正确选项。
2．【教材原句】..survivors whose homes had been destroyed.(U4P26)
→【真题呈现】That's the new machine ______parts are too small to be seen.
A．that B．which C．whose D．what
【要点解析】考查定语从句。句意：那就是那台新机器，其许多零件太小而看不到。先行词是the new machine, whose表示“……的”，代替the new machine's，在定语从句中作定语，修饰parts。
3．【教材原句】The man was sleeping downstairs when the earthquake happened. (U4P31)
→【真题呈现】Because of the heavy traffic, it was already time for lunch break __ she got to her office.
A．since B．that C．when D．until
