寻找特殊倒装标志，巧记特殊倒装句型 有些倒装句型的构成不是将动词提前，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，这种特殊倒装句型常有下列标志：
1.可将句型prefer to do A rather than do B(宁愿做Ａ而不愿做Ｂ)中的rather than do B前置至句首，从而构成特殊倒装句型。
例如：
rather than ride on a crowded bus, he always prefers to ride a bicycle.
2.As(尽管)引导让步状语从句时一般将按通常语序应置于句未的表语、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.
注意：如果表语为单数可数名词，前置时应去掉不定冠词。
例如：child as he is, he has been to many places.
Much as I want to see him, I dare not do it.
Go as you may, you can’t see him.
3.在if 虚拟条件从句中，如果从句的谓语动词含有were, had , could, should,可将这四词提至句首，将连词if 省去，从而构成特殊倒装句型。
例如：
had it been possible, would you have done it?
Were I you, I wouldn’t go.
Could I do it, I would do it.
Should it rain tomorrow, I wouldn’t go.
