特殊倒装：

有些倒装句型的构成既不是将动词提前，也不是将助动词提前（或加助动词），而是将句子中的某部分内容提前，常有下面两种情况：

①As(尽管)引导让步状语从句时一般将表语、动词或副词前置至句首，从而构成特殊倒装句型。例如：

●Young as he is, he knows a lot.（原句为：as he is young, he knows a lot）

●Much as I want to see him, I dare not do it.（原句为：as I want to see him, I dare not do it）

●child as he is, he has been to many places.(原句为：as he is a child, he has been to many places)，注意：如果表语为单数可数名词，前置时应去掉不定冠词。

②在if 虚拟条件从句中，如果从句的谓语动词含有were, had , could, should,可将if 省去，将句子变为一般疑问句形式的倒装。例如：

had it been possible, would you have done it? （原句为：if it had been possible, would you have done it）

练习题：

1, ＿＿＿,we could forgive him for his mistakes!

     A. Were he still a child    B. If he is still a child

     C. Is he still a child       D. He were still a child

解析：本题空格处补充完整应为：If he were still a child。if引导虚拟语气条件状语从句，在口语中或非正式场合可以把if省略掉而将剩下的部份变成一般疑问句，则If he were still a child变为were he still a child，故选A。

2, She didn’t come to the party last Sunday. ＿＿＿,she must have made the party more exciting.

    A. If she came      B. Would she come

    C. Had she come       D. Did she come

解析：句意为“她上周星期天没来参加晚会，如果她来了，她一定使这个晚会更有趣”，根据句意，明显知道空格处是虚拟语气，与过去相反，应该用过去完成时（此题是虚拟条件句；在虚拟条件句中，若与过去相反，则从句用过去完成时，主句用would+have done），应该是：If she had come；

本题去掉if后为：she had come，将此句变成一般疑问句为：Had she come，故选C。

3. Little Tom is an orphan. ＿＿＿＿＿,he has to make a living by himself.

     A. A child as he is        B. Child as he is

     C. Child as is he        D. A child though he is

解析：Child as he is＝Although he is a child。as引导让步状语从句时，通常要把作表语的形容词或名词、作状语的副词或动词原形提前到句首，此时as后面用陈述句式，故排除C；

同时注意，必须把作表语的单数名词前的不定冠词去掉，此题则将child前的冠词去掉，故选B。
