你会正确使用虚拟语气的倒装形式吗
请看典型考题：__________ your address,I would have written to you. A. Did I know B. Were I to knowC. Had I known D. If I should know此题应选 C.这是虚拟语气的倒装形式.当虚拟条件句中含有 were,had,should,could等动词时,可以将if省略,然后将 were,had,should,could 等词移至句首：1. If he should fail,he would kill himself. →Should he fail,he would kill himself. 万一失败,他就会自杀.2. If I were you,I would do it at once. →Were I you,I would do it at once. 假若我是你,我就会马上做.3. If I could do it,I would. →Could I do it,I would. 要是我能做此事,我一定会做.4. If he had seen you yesterday,he would haveasked you about it. →Had he seen you yesterday,he would haveasked you about it. 他昨天要是看到了你,他就会问你这事了.
