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．狀語從句的省略 當狀語從句的主語和主句主語保持一致，且從句謂語動詞中含有be動詞，可以將狀語從句中的主語和be動詞一起省略。 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等類似結構中，it is常可省。 Hold your head high if necessary. 3．狀語從句與名詞性從句的區別 wh－ 開頭的詞既可引導狀語從句，相當于no matter wh－；也可引導名詞性從句，相當于anything that / anyone who；分辨它們的竅門在于wh－引導名詞性從句時，去掉從句，主句成分意思不完整，而wh－引導狀語從句時，去掉從句，主句意思成分完整清晰。 Whoever you are(＝No matter who you are)，you must obey the regulations.(狀語從句) Whoever arrives first (＝No matter who arrives first) will win the gold medal.(主語從句) 4．狀語從句與定語從句的區別 (1)where與when引導的狀語從句容易與它們引導的定語從句相混淆。when與where引導定語從句時，有先行詞，可被介詞＋which替代；它們引導狀語從句時，主句中沒有相應的先行詞，也不能被介詞＋which替代。 The graduates should go where they are needed most.(狀語從句) The graduates should go to the place where / in which they are needed.(定語從句) I was the happiest when my parents were together with me.(狀語從句) I was the happiest during the time when / at which my parents were together with me.(定語從句) (2)so / such...that引導的結果狀語從句和so / such...as引導的定語從句 so / such...that引導結果狀語從句時，that 沒有任何意義，也不在從句中充當任何成分；而so / such...as引導定語從句時，as為關系代詞，在從句中必須充當句子成分，代替先行詞。 The question is so difficult that no one can answer it.(狀語從句) It is so difficult a question as no one can answer.(定語從句) He is such a good speaker that we all believe him.(狀語從句) He is such a good speaker as we all believe.(定語從句) 5．狀語從句與強調句型的區別 It was the factory where the accident happened.(地點狀語從句，it指代那家工廠) It was in the factory that the accident happened.(強調句型，it無具體意義，僅構成強調句型) It was midnight when he arrived Changsha.(時間狀語從句，it指時間) It was at midnight that he arrived Changsha.(強調句型，it無具體意義，僅構成強調句型) 從A、B、C、D四個選項中，選出可以填入空白處的最佳選項。 ()1.He made a mistake，but then he corrected the situation ________ it got worse.
