Had he been there yesterday, he would have seen the film. Should it snow tomorrow, we wouldn’t go out. If I were you, I would try it again.If he had been there yesterday, he would have seen the film.If it should snow tomorrow, we wouldn’t go out. 注意(2)if的省略 非真实条件句中的条件从句有时不表示出来,只暗含在上下文中,这种句子叫做含 蓄条件句。含蓄条件句大体有三种情况: a. 条件暗含在短语中。如:without, but for, in case of. etc What would I have done without you? It would be easier to do it this way. But for your help we couldn’t have succeeded in the experiment. b. 条件暗含在上下文中.如:or,otherwise You might stay here forever. (可能暗含if you wanted to) We would have succeeded. (可能暗含if we had kept trying) Your reputation would be ruined. (可能暗含if you should accept it)I was very busy yesterday. Otherwise I would have come to see you. 注意(3) 错综时间条件句 虚拟条件句中的主句和从句的动作发生的时间不一致,这时主句和从句的谓语形式应按照各自动作发生的实际时间来表达If you hadn’t lent me some money, I couldn’t have bought the new house and most likely I would be still living in the dangerous house now. 假若你不借钱给我, 我不可能买下这幢新房,很可能现在还住在危房里。 (从句说明过去,主句说明过去和现在。) 虚语拟气在名词性从句中的使用(一) 一个坚持 两个命令 四个建议 四个要求 注:以上动词后所接宾语从句中谓语用“(should) + 动词原形”。 insist order, commandadvise, suggest, propose,recommenddemand , require, request, urge I advised that you ___ the job as soon as possible .
