Question

_________ smoking, he would not have got cancer in the lung.

A．Was he given up	B．Had he given up
C．Did he give	D．If he gave up

Answer 1

B

試題分析：考查虛擬語氣的倒裝：由于主句謂語是would not have got，這表明是對過去事實作出的假設，所以從句謂語應該是 had given up。當虛擬條件句中有 had should were 等詞時，通�？梢允÷� if，并將 had should were 提前置于句首答案B。
點評：在虛擬語氣條件句中從句謂語動詞有were, had, should等詞，可將if 省略，把 were, had, should 移到主語之前，采取部分倒裝。但注意not不能倒裝，還有如果had是實意動詞也不能倒裝。
