英语中的虚拟语气是四、六级考试的必考考点。如果你掌握了以下十八个例句,再做好文后所配的练习,虚拟语气难题就可以迎刃而解了。
一、虚拟语气在条件从句中的用法
(一)形式
略
注:
1.在从句中,be动词多用were的形式。在口语中,如果主语是第一、第三人称单数的话,be动词可用was,但人们总是说:If I were you...
2.主句中的谓语可以由would,should,could和 might这四个不同的情态动词来构成。
3.与将来事实相反的条件从句中,谓语有三种不同的形式:过去式、were +to do或should +do。
例句1:If I were you,I would study hard.我要是你的话,我就会好好学习。(与现在事实相反)
例句2:If I had studied hard,I would have passed CET-6 last semester.我要是早就好好学习的话,那么我上个学期就通过六级考试了。(与过去事实相反)
例句3:If Iwere to pass CET-6,I would treat you to dinner at KFC.我要是过了六级考试,就请你去吃肯德基。(与将来事实相反)
(二)省略/倒装
如果在虚拟从句中包含有一个助动词、情态动词、动词be或have,则可把if省略,把上类动词提到主语之前,使用倒装语序。
例句4:Had it not been for the PLA,we wouldn't have been able to beat the flood.4要不是人民*,我们是无法战胜洪水的。
例句5:Were he here now,he would certainly help me.5他要是在这里肯定会帮我的忙。
注4:例句4中的从句部分出现了否定词not,如果把该句还原成正常语序,应该是:
If it hadn't been for the PLA,we wouldn't have been able to beat the flood.
但是一旦句子发生了省略,就必须把hadn't分开,否定词not还原,放在主语之后,不可写成Hadn't it been for的形式。
注5:在虚拟条件从句中,动词be在正常语序中常用were,在口语中,当主语是第一、第三人称单数时,可用was,但在if的倒装句中,必须用were。
(三)错综时间条件句
有时,从句和主句中所表示的动作发生的时间是不一致的,这时就要根据其所表示的时间来进行调整。
例句6:If I were you,I would have gone to see the doctor.我要是你,我早就去看病了。(从句与现在事实相反,主句与过去事实相反)
例句7:If you had gone to see the doctor,you would be all right now.你要早去看病,你现在就没事了。(从句与过去事实相反,主句与现在事实相反)
(四)含蓄条件句
虚拟的条件有时可以不用条件从句来表示,而是通过某些介词短语来表达。
例句8:But for the English test,I would have gone home this week.6要不是英语测试,我这个礼拜就回家了。
注6:除了but for(要不是)以外,能够表示虚拟条件的词和短语还包括:but that(要不是)、without(没有)、otherwise(否则)、or(不然)、under...circumstances(在……的情况下)、in the past(在过去)等等。

二、虚拟语气在其他从句中的用法
(一)宾语从句
1.wish后的宾语从句
例句9:I wish I were as young as you.7我希望自己像你一样年轻。
注7:wish从句后使用虚拟语气时,动词的形式根据所表示的时间概念而采用不同形式:过去时(与现在相反)、过去完成时(与过去事实相反)或过去将来时(与将来事实相反)。
2.would rather和would sooner后的宾语从句
两个词组都表示宁愿、宁可的意思,后面如用宾语从句,动词采用过去时(与现在或将来事实相反)或过去完成时(与过去事实相反)。
例句10:I'd rather I hadn't met you.8我宁愿从来就没遇见过你。
注8:would rather和would sooner两词组除了要掌握它们后面宾语从句中虚拟语气的用法以外,还要知道这两个词组后面都可以直接加动词原形,这也是四、六级考试中的一大考点,如:美国歌曲《山鹰》中的第一句歌词就是:I'd rather be asparrow than a snail.其中,就使用了句式would rather do than do(宁愿做……而不做……)。
3.suggest等动词后的宾语从句
表示主观判断、推测、建议、命令和要求的动词通常引起虚拟的宾语从句,此类动词后的宾语从句中采用should +do、should可以省略的虚拟语气形式。该类动词包括:
(1)高中词汇:advise(劝告)、ask(要求)、decide(决定)、insist(坚持)、order(下令)、suggest(建议)等。
(2)四、六级常考词汇:command(命令)、demand(要求)、desire(渴望)、propose(提议)、recommend(劝告)、require(要求)等。
(3)其他词汇:consent(同意)、deserve(值得提
起)、maintain(主张)、move(提议)、urge(极力主张)、 vote(提议)等。
例句11:I recommend that you all be diligent if you want to pass the exam.如果你们要考及格,我劝你们勤奋学习。
(二)主语从句
在It is +形容词/某些动词的过去分词+主语从句的结构中,从句的谓语动词须用动词原形或 should +do的形式。这些形容词包括:
(1)高中词汇:decided(决定的)、important(重要的)、ordered(命令的)等。
(2)四、六级常考词汇:advisable(合理的)、demanded(要求的)、desired(期望的)、desirable(合乎需要的)、essential(紧要的)、insistent(坚持的)、natural(自然的)、preferable(更可取的)、proposed(建议的)、 recommended(推荐的)、required(要求的)、urgent(紧迫的)、vital(极其重要的)等。
(3)其他词汇:appropriate(适当的)、arranged(安排好的)、better(较好的)、imperative(迫切的)、possible(可能的)、probable(可能的)、resolved(决心的)、 strange(奇怪的)、suggested(建议的)等。
例句12:It is highly desirable that a new mayor be appointed for this city.这座城市急需任命一位新*。
(三)表语从句和同位语从句
有些名词引起的表语从句或同位语从句中,谓语动词须用动词原形或should +do的形式。这些名词包括:advice(忠告)、decision(决定)、demand(要求)、desire(渴望)、idea(想法)、motion(提议)、necessity(必要性)、order(命令)、plan(计划)、preference(偏爱)、proposal(建议)、recommendation(推荐)、requirement(要求)、suggestion(建议)等。
例句13:His proposal is that we turn off TVfor half an hour every day.他建议我们每天少看半个小时的电视。
特别提示:从以上的各类从句中我们可以得到以下的推论,即当一个动词后面的宾语从句中要使用(should)+do的虚拟语气形式时,则可推理出用法相同的一组从句。以动词advise为例:
(1)I advise that we stay and wait here.(动词后的宾语从句)
(2)It is advised that we stay here.(It is +动词的过去分词+that引导的主语从句)
(3)It is advisable that we stay here.(It is +由该动词转换的形容词+that引导的主语从句)
(4)My advice is that we stay here.(由该动词转换的名词后的表语从句)
(5)I offered the advice that we stay here.(由该动词转换的名词后的同位语从句)
(6)I think it advisable that we stay here.(由该动词转换的形容词作宾语补足语,it为形式宾语,真正的宾语从句中使用虚拟语气)
以上六类从句中所使用的都为(should)+do的虚拟语气形式。

(四)状语从句
1.as if/as though引导的状语从句
as if/as though(仿佛、好像)引起方式状语从句,从句中的虚拟语气形式与wish后的宾语从句相同:
a.一般过去时(表示与现在事实相反)
b.过去完成时(表示与过去事实相反)
c.would +do(表示与将来事实相反)
例句14:You look as if you had seen a ghost.你看起来好像撞见鬼了。
2.lest/in case /for fear that引导的状语从句
lest(以防、以免)、in case(万一、以防)、for fear that(因恐、免得)引起的状语从句中,谓语动词要使用(should)+do的形式。
例句15:The old woman walked slowly lest she(should)slip.老太太走得很慢,以免滑倒。
3.whoever等引导的状语从句
由连接代词whoever(无论谁)、whatever(无论什么)、whichever(无论哪个)等和连接副词however(无论如何)、whenever(无论何时)、wherever(无论哪里)等及 no matter+how/what/when /where /who(无论怎样/什么/何时/哪里/谁)构成的词组引导的让步状语从句,若表示说话人对现在或将来的推测,谓语动词常用虚拟语气,形式为动词原形或may /might+do。
例句16:Whichever be the case,my situation remained the same.无论是哪种情况,我的处境都一样。
(五)定语从句
It is time(是……时候了),Itis about time(差不多是……时候了),It is high time that(该……了)句式中,that引导的定语从句中用过去时表示虚拟。
例句17:It is time that we protected our environment.我们应该保护我们的环境了。
三、虚拟语气在表示祝愿的句子中的应用
在if only或if...only(但愿、要是……就好了)引起的表示遗憾的感叹句中,谓语动词使用虚拟语气,形式为过去时。
例句18:If only I could see Jordan.我要是能见到乔丹就好了。
以上的十八句是笔者精心设计的,每一个句子都是虚拟语气的一个考点,如果能够把这十八句融会贯通,达到举一反三的程度,虚拟语气部分则可轻松过关。
