　　【溫馨提示】

　　1. “連詞+省略結(jié)構(gòu)”通�？梢暈橐环N緊縮的狀語從句，即認(rèn)為是省略了從句的主語（與主句主語一致）和主語后的動(dòng)詞be。如：

　　Look out for car’s when (your are) crossing the street. 過街時(shí)注意車輛。

　　He acted as if (he was) certain of success. 他的舉止就像一定會(huì)成功一樣。

　　有時(shí)可視為省略了it is（其中的it并非主句主句）。如：

　　lf (it is) possible, please let me know by this evening. 如果可能的話，請(qǐng)?jiān)诮裢硪郧案嬖V我。

　　Where (it is) necessary, improvements will be made. 哪兒需要，就在哪兒改進(jìn)。

　　2. 并不是所有的狀語從句都可以用以上辦法來緊縮的，如原因從句就不能用這種辦法來處理。

　　3. 與上面提到的省略結(jié)構(gòu)相似且經(jīng)常在高考中出現(xiàn)的還有if not…這一種形式。如：

　　His pronunciation, if not good, is at least tolerable. 他的發(fā)音如果說不算好，也還過得去。
