He will pay a visit to you as soon as he gets here. He said whenever I was in trouble I could turn to him. 2．状语从句的省略当状语从句的主语和主句主语保持一致，且从句谓语动词中含有be动词，可以将状语从句中的主语和be动词一起省略。 When in trouble，ask the chairman himself. Although frightened，he managed to run away. While crossing the road，you should watch out. 另在if it is possible，when it is necessary等类似结构中，it is常可省。 Hold your head high if necessary. 3．状语从句与名词性从句的区别 wh－开头的词既可引导状语从句，相当于no matter wh－；也可引导名词性从句，相当于anything that / anyone who；分辨它们的窍门在于wh－引导名词性从句时，去掉从句，主句成分意思不完整，而wh－引导状语从句时，去掉从句，主句意思成分完整清晰。 Whoever you are(＝No matter who you are)，you must obey the regulations.(状语从句) Whoever arrives first (＝No matter who arrives first) will win the gold medal.(主语从句) 4．状语从句与定语从句的区别 (1)where与when引导的状语从句容易与它们引导的定语从句相混淆。when与where引导定语从句时，有先行词，可被介词＋which替代；它们引导状语从句时，主句中没有相应的先行词，也不能被介词＋which替代。 The graduates should go where they are needed most.(状语从句) The graduates should go to the place where / in which they are needed.(定语从句) I was the happiest when my parents were together with me.(状语从句) I was the happiest during the time when / at which my parents were together with me.(定语从句) (2)so / such...that引导的结果状语从句和so / such...as引导的定语从句 so / such...that引导结果状语从句时，that 没有任何意义，也不在从句中充当任何成分；而so / such...as引导定语从句时，as为关系代词，在从句中必须充当句子成分，代替先行词。 The question is so difficult that no one can answer it.(状语从句) It is so difficult a question as no one can answer.(定语从句) He is such a good speaker that we all believe him.(状语从句) He is such a good speaker as we all believe.(定语从句) 5．状语从句与强调句型的区别 It was the factory where the accident happened.(地点状语从句，it指代那家工厂) It was in the factory that the accident happened.(强调句型，it无具体意义，仅构成强调句型) It was midnight when he arrived Changsha.(时间状语从句，it指时间) It was at midnight that he arrived Changsha.(强调句型，it无具体意义，仅构成强调句型) 从A、B、C、D四个选项中，选出可以填入空白处的最佳选项。 ()1.He made a mistake，but then he corrected the situation ________ it got worse. A．until
