英语虚拟语气专项训练 ?一、虚拟条件句：?条件状语从句是非真实情况，在这种情况下要用虚拟语气。?1、条件从句与现在事实不一致，其句型为：?句型1：if ＋主语＋过去时，主语＋should（could, would, 或might）＋动词原形,如：?(1) if i?were?you, i?would study?hard.?(2) if it?rained, i?would not be?here now. ?2、条件从句与过去事实不一致，其句型为：?句型2：if ＋主语＋had＋过去分词，主语＋should（could, would, 或might）＋have ＋过去分词，如：?(3) if the doctor?had come?last night, the boy?would have saved.?(4) if i?had not studied?hard, i?would have failed?in the exam last term. ?3、条件从句与将来事实不一致，其句型为：?句型3：if ＋主语＋过去时/should ＋动词原形/were to＋动词原形,主语＋should（could, would, 或might）＋动词原形 ，如：?(5) if it?should rain?tomorrow, we?would stay?at home.?(6) if i?were to go?to the moon one day, i?could see?it with??? my own eyes.?(7) if you?missed?the film tonight, you?would feel?sorry. 注意问题：?1、if条件句中绝对不可以出现“would”。?2、根据句中的时间状语，有时可能出现“混合虚拟”的情况，即主句可能是现在的情况，条件句也许是发生在过去的情况，但都要遵守上述句型,如: （8）if i were you, i would not have missed the film last night. (现在---过去)（9）if they had started in the early morning, they would arrive in half an hour(过去---将来)（10）if you had asked him when you saw him last time, you would know what to do now. (过去---现在) (11)if you?had studied?hard before, you?would be?a college student now and you?would graduate?from a college in four years’ time.?3、在条件句中如果出现were, had, should可省去if，将主语与这些词倒装，例如：(12)?had?the doctor?come?last night, the boy?would have saved.(13)?were?i?to go?to the moon one day, i?would see?it with my?? own eyes.(14)should?it?rain?tomorrow, we?would stay?at home. 二、名词性虚拟语气：?在表示命令、建议、要求、惊叹时的名词性从句中需用虚拟语气，基本句型：?句型4：主语＋（should）＋动词原形， ①当宾语从句从的谓语是suggest, request, insist, desire,demand, propose, order, command, arrange等动词时,如: (15) mother insisted that john?(should )go?to bed at 9 o’clock.（宾语从句）(16) it was required that the crops?(should) be harvested?at once.（主语从句） ② advice, idea, order, plan, demand, proposal,suggestion, request等名词之后的表语从句和同位语从句中.如:??? (17) the suggestion that he (should) be invited was rejected.（同位语从句）(18) their demand is that their wages?(should )be increased.（表语从句）注意：在这种句子中
