[注释]本题测试交错时间的虚拟语气。从句是表示过去时间的虚拟条件，if省略，主语it与助动词had倒装。虚拟条件句也可写成这样：
Ifithadnorbeenforthetimelyinvestmentfromthegeneral public。这是重点句型，在各类测试中常考。
4.在表示建议、命令、要求、忠告等动词的后面，其宾语从句的谓语用“should+动词原形”表示虚拟语气
常用的此类动词有：
表示“要求”的：
ask, desire, request, demand, require, beg
表示“提议、劝告、建议”的：
decide, order
表示“主张”的：
maintain, urge
3)用“would rather/had rather' wouldjust as soon"表示“宁愿、但愿”，后面的宾语从句谓语用过去式或动词原形表示对将来的要求，用过去时表示对现在的愿望，用过去完成时表示对过去做的事的懊悔。
Don' t live in the world, I would rather( I would just as soon) you die.I would rather you go tomorrow.
5.在“It is (was)+形容词（或过去分词）+that„„”结构中，主语从句的谓语也用“should+原形动词“表虚拟语气
美国英语中省去should,常用的形容词和过去分词有：
表示“要求”的：
required, demanded, requested, desired。
表示“建议”的：
表示“迫切、紧近、重要”的：
He took a map with him lest he (should ) lose his wag there.
2) “whether不管、无论”引导的让步状语从句，有时用动词原形。
All things, whether you know or don' t know, exist in the world.
例：
It was necessary that we (should) make everything ready ahead of time.It is required that nobody (should)smoke here.
6.由下列名词或短语引导，或含有某些词的从句中应用的虚拟语气
1) “Iest以免、惟恐”引导的从句用“should+动词原形”。
IwishIhadn'thurthim so much。
3)用wish表示对将来事情的愿望。其句子结构为宾语从句的结构，谓语为would/could/might+动词原形。例：
2.用在一般虚拟条件句中的虚拟语气
1)表示与现在、过去、将来事实相反的假设
①与现在事实相反的假设。
其句子结构为：
从句：
if+主语+动词的过去式（be变were）+其他
例1：Christiestaredangrilyatherbossandturnedaway,asthough__outoftheoffice.
A. went
B. gone
C. to go
D. would go
[答案]
C. to go
[注释] as though或as if引导的状语从句中,从句主语和主句主语相同时,从句中可省略主语和部分谓语,如：1) She paused, as if to let the painful memories pass. (省略she wanted)2)From time totimeJasonturnedround as though searching for someone. (省略he were)3)Theboystarted,asifawakenedfromsomedream.(省略hewere)由此可见,本题中省略shewanted。
Theoldmanlookedatthepicture,hefeltasthoughhehadgonebacktotime20yearsago.（用过去完成式表示与过去相反的事实）
They talked and talked as if they would never meet again (would+动词原形，表示与将来事实相反)
例：
If you had studied harder last term, you could have passed the exam.③表示对将来事实实现的可能性不大的假设。
其句子结构为：
从句：
If+主语+should (were to )+动词原形+其他

虚拟语气与习题
1.动词wish后宾语从句中的虚拟语气
1)用wish表示现在的祝愿和抱歉。
其句子结构为：
宾语从句的谓语be用were(was)，实义动词用过去式。例：
Iwishtheywereathome this time.
2)用wish表示对过去事情的遗憾。
其句子结3;现在完成时。例：
6)用“without/butfor/intheabsenceof”表示“要不是”，“如果没有”（相当于ifitwerenot for„）表示条件时，句中一般用虚拟语气。（也可用陈述语气）

In the absence of water and air, nothing could live
3.可以引起与事实相反的方式状语从句，用虚拟语气;由asif、asthough引起的与事实相反的句子，不论主句的谓语是现在时或者说过去时，其谓语表示的时间概念和句子结构，都基本上与wish后的宾语从句相同。例：
Johnpretendsasifhedidn'tknowthethingatall,butinfactheknowsitverywell.(用过去式表示与现在事实相反的假设)
[译文]要不是老百姓的及时投资，我们的公司不会像现在这样兴旺。
例4: The millions of calculations involved, had they been done by hand, all practicalvalue__ by the time they were finished.
③从句表示过去，主句表示将来。
Ifwehadn'tmadequatepreparations,weshouldn'tdaretodotheexperimentnextweek。
④从句表示将来，主句表示现在。
If we shouldn’t have an exam this afternoon, I would go shopping now.
7)由“providing (that)/ provided (that)/on condition that/ in order that”引导的条件从句或目的从句，根据情况，可用虚拟语气。（有时也可用陈述语气）
They are willing surrender provided they are given free passage.
[译文]克里斯蒂愤怒地盯了老板一眼并转过身去，似乎想走出办公室。
例2:I'dratheryou__bytrain,becauseIcan'tbeartheideaofyourbeinginairplanein such bad weather.
A. would go

表示“同意、坚持”的：
consent, insist

He insisted that we (should) tell him the news.
The advice is that we (should) leave at once.
I would rather everything hadn' t happened in the past.
4)用“had hoped”表示原来希望做到而实际上未能实现的事情，其宾语从句的谓语用“would+动词原形”。
I had hoped that she would go to the U.S. and study there, but she said she liked to stayin China.
5)在“Itis（high/about）time+that”引导的定语从句中，定语从句的主谓语用一般过去时，偶尔也可以用would(或should)+动词原形，或had rather (would rather)+动词原形。It is high (about)time that we left/should leave/ had better leave/had rather leave/ wereleaving.(注意与“This is the first/second„time”后从句中用现在完成时的区别。
