马上就要开学啦~特意送上虚拟语气语法讲解(第一次发节目，好紧张啊)话不多说，一起来学习吧！

3.与将来事实相反的虚拟

(1) If + should + v., ... would + v. （可能性很小）（译作“万一”）

(2) If + did / were to + v ..., would + v. （完全不可能）

4.特殊重点

简单联想记忆：

● 下列动词后的“宾语从句”中需要用虚拟形式，即should + 动词原形，shoud在美国英语中要省略（TOEFL语法考点）。此类常见的动词有：order, ask, decide, demand, require, recommend, suggest（建议）, insist（坚决要求）, advise, etc.

● 下列名词后的同位语从句中要用“should + 动词原形”（should可省去）的虚拟。此类常见的名词有：suggestion, order, request, demand, importance, proposal.

He made a suggestion that we (should) have a fancy dress party.
他建议我们举办一个化妆舞会。
I think it is a thing of importance that it (should) be done soon.
我认为尽快完成这件事非常重要。

● It is / was important / necessary / natural / essential / advisable / strange / surprising, ect. + that +主语+ should + v.

It is strange that you should say such a thing.
你这么说真的很奇怪。

● wish后的宾语从句中，as if 后的状语从句中，须用下列的虚拟形式：
主 + wish+ (that) + 主 + did / were（指现在）
had done（指过去）
would+ v.（指将来）

我真希望现在可以见到我叔叔。

我真希望昨天就见到叔叔。
