2018年PETS三级听力心得技巧：虚拟语气与条件关系题
虚拟语气与条件关系题
1、虚拟语气与条件关系如何区分
2、条件关系句型都有哪些
if, unless, suppose, in case, as long as, with / without
3、虚拟语气的句型
1)if虚拟句 a、表示与现在事实相反的虚拟语气，谓语的主要形式为： 从句：过去式 主句：should / would / could / might + 动词原形 b、表示与过去事实相反的虚拟语气，谓语的主要形式为： 从句：had + 过去分词 主句：should / would / could / might + have + 过去分词 c、表示与将来事实相反的虚拟语气，谓语的主要形式为： 从句：过去式 主句：should / would / could / might + 动词原形
特殊形式： 当从句所发生的时间与主句发生的时间不一致时，可以使用错综时间条件句 如：一个是与过去事实相反，一个是与现在事实相反 If we had left a little earlier, we wouldn't be late.
2)If only后的从句，用过去时表示与现在相反，用过去完成时表示与过去相反，也可用情态动词could, would等 + 动词原形，表示对将来的憧憬，如： If only it would stop snowing! 3)用as if, as though引导的状语从句中多用虚拟语气，用过去时表示与现在相反，用过去完成时表示与过去相反，如： You look as if you had seen a ghost. 4)在以for fear that, lest, in case引导的目的状语从句中，可以用should + 动词原形表示虚拟，也可以用may或might，如： He is studying hard for fear that he should / might / may fail the exam. 5)wish后面的虚拟宾语从句，用过去时表示与现在相反，用过去完成时表示与过去相反，也可用情态动词could, would等 + 动词原形，表示对将来的憧憬，如： I wish I had been to France.
4、虚拟语气与关系推理题答题的要领 虚拟语气和条件关系句都是考点句。二者的推理方式不同，因为虚拟语气句往往与事实相反，所以考的是正反推理;条件关系句考的是假设推理，因此区分虚拟语气与条件关系句是解题的关键。
