虚拟语气在新概念英语中课文中非常的常见。将课文中所有虚拟语气例句摘出来学习很有必要。
本文假设你对虚拟语气语法已经有所了解,并学习过新概念英语第三册。以下例句可以通过英语事事通软件查询对应的课文:
 

1. 简单的过去的虚拟

Who could have imagined, in the mid 1970s, for example, that by the end of the 20th century, computers would be as common in people's homes as TV sets?举个例子吧,在20世纪70年代中叶又有谁能想得到在20世纪末的时候,家庭用的计算机会像电视机一样普遍?
could+ have done(不定式完成式)表示过去没有实现的可能性:某事可能发生,但是却没有发生。那么它是过去对未来的某种推测,因此其后的宾语从句应该用表示过去将来的情态助动词“ would”
The cave might never have been discovered had not the entrance been spotted by the distinguished French pot-holer, Berger.若不是法国著名洞穴探险家伯杰由于偶然的机会发现了这个洞口的话,这个洞也许不会为人所知。
 

2. 简单的现在的虚拟

would

Might

3. Should + do

Should通常省略(尤其美语中)
advise sb. to do sth
比较 advise that sb. should do sth
Grammar:表命令、建议和要求的以下动词一般要接虚拟语气即v+sb.( should)do,美语中常省略 should
advise, agree, demand, insist, command, decide, ensure, grant, order,instruct, propose, recommend, require, request, suggest, urge

4. Should have

5. Wish

注意wish后面的句子虚拟语气(过去完成)subjunctive mood/thought mood
Wish+宾语从句
hope是不能加subjunctive mood宾语从句的
主+wish+(that)+主+(did/were现在)(had done过去/could,would have done)(would do将来)
注意be动词在虚拟语气中无论什么人称都是were。
