2、含蓄虚拟，用介词短语代替if从句引导的虚拟（1）without = but for 若不是，要不是，如果没有3、错综（混合）虚拟，主从句事态不在一个时间段（技巧：对号入座，主套主，从套从如：如果我是你（现在），我早把这书买了（过去）。
我要赶上那趟车（过去），现在就坐这上课了（现在）。
﹡（二）其他形式虚拟（单选、挑错常考到，非常重要）从句后是现在时即与现在相反，是过去时即与过去相反，是将来时即与将来相反。

专四语法重点难点资料
On hearing the bad news, she cried.
I’ll never forget seeing that film for the first time.
2）动名词的语态 doing being done having done having been done
用虚拟语气的其他一些情况
• 3.在假设情况由上下文或其他方式表现出来 的句子中，有时候上下文或其他方式也能 表示假设情况，这时仍需用虚拟语气。例 如：
• It would have been considered impossible in the past.
用虚拟法 （倒装） • Eg. Whether it (may) be fine or rainy, we
动名词的时态和语态
1）动名词的时态：一般式和完成式 如G.的动作没明确表示出时间是与谓语同时
发生或在谓语之前发生，用一般式。
We are interested in _____ (play) chess.
如G.的动作发生在谓语动词所表示的动作之 前，通常用完成式。
I’m sorry for not _____ (keep) my promise. 但在某些词后，常用一般式，尽管其动作是
• = If I hadn’t been too busy, I would have gone to the party with you.
• （前事实后虚拟）标志: otherwise
Eg. I was too busy then, otherwise I would have gone to the party with you.

语法与词汇专项语法核心考点一：从属分句复合句 = 主句 +从句（ 1 个或 1 个以上）要点 1 从属分句是复合句必不可少的组成部分，以语法功能作为分类标准，从属分句可以分为状语从句、关系从句（即定语从句）和名词性从句。
其中状语从句可分为时间、地点、原因、结果、程度、目的、条件、让步和方式等；名词性从句可分为主语从句、宾语从句、表语从句、同位语从句。
要点 2 状语从句的考点集中在方式、条件、让步、方式和时间状语从句上；关系从句的考点集中在关系代词的选择，限制性定语从句和非限制性定语从句的区别；名词性从句的考点集中在宾语从句和同位语从句。
