Subjunctive Mood

                                     虚拟语气

一,语法点归纳

We learnt subjunctive mood last two weeks. There are two forms of the subjunctive : be-subjunctive and were-subjunctive. The be-subjunctive is realized by the base form of the verb. The were-subjunctive has only one form were. In addition to the be-subjunctive and the were-subjunctive , we can use past tense forms of verbs an past tense modals for the same prupose.

 

二,课后练习精选

1,Q:Rewrite the following, using be-subjunctive

    Let it be understood that both side are willing to reach an agreement.

  A: Be it understood that both side are willing to reach an agreement.

  释:be-型虚拟式用于某些公式化语句中可表示祝愿,诅咒,禁止等意义。

 

2, Q:Rewrite the following, using be-subjunctive

    The ambassador will stay there if necessary.

   A:The ambassador will stay there if need be.

   释:need be = necessary

 

3,Q:Put the verbs in brackets into the proper subjunctive form

    He behaves as though he were (be) better than us.

 释:were-型虚拟式常用于as though引导的让步状语分句中,表示非真实的让步

 

4, Q:Put the verbs in brackets into the proper subjunctive form

     He is my best friend, my second self, as it were (be). 

   释:在as it were (作so to speak解,即“宛如”,“好比”)结构中只用were,不用was

 

5, Q:Put the verbs in brackets into the proper subjunctive form

     He fought as hard as if his wife were (be) in danger.

   释:were-型虚拟式常用于as if 引导的条件状语分句中,表示非真实的条件

 

6, Q:Put the verbs in brackets into the proper subjunctive form

     We suggest that his applicant apply (apply) next year.

     释:be-型虚拟式是以动词原形表示的,即不管主语是什么人称,动词一律用原形。而be-型虚拟式用于表示建议等词语之后的that-分句中。如,该句中的We suggest that(我们建议)

 

7, Q:Put the verbs in brackets into the proper subjunctive form

     Give him food lest he perish (perish).

  释:be-型虚拟式能用于由if, though, whatever, lest, so long as等引导的分句中表示推测,让步,防备等含义。如,该句中的lest

 

8,Q:Fill in the blanks with the correct forms of the verbs in brackets

   I wish you hadn’t given (not give) him my phone number. (=I am sorry you gave it to him )

 释:had not done表示不该做却做了的事情。句中,“我”不希望“你”把号码给“他”,而“你”却已经给了

 

9, Q:Fill in the blanks with the correct forms of the verbs in brackets

     If only I had been (be) insured! (=But I wasn’t insured)

   释:had done 表示应该做却没有做的事情。句中,“我”希望“我”有加入保险,可是事实上“我”没有

 

10, Q:Fill in the blanks with the correct forms of the verbs in brackets

      It’s just struck midnight. It’s high time we went (go) to bed.

    释:It’s high time这结构常用于动词的过去时表示假设意义

 

三, 我的专四语法宝典

1,Q: Acute hearing helps most animals sense the approach of thunderstorms long before people ____

A, do     B, hear      C, do them     D, hearing it

  答案:选A

  解释:句意:敏锐的听觉使多数动物能远在人之前感觉到雷雨的到来。此句考查do的指代作用。这里do来代替前文的sense the thunderstorms以避免重复,且时态都是一般现在时,故选A

 

   2,Q:This is an illness that can result in total blindness ___ left untreated.

      A, after    B, if     C, since      D, unless

    答案:选B

    解释:句意:这种疾病如果不得到及时治疗,将导致完全失明。此句考查连词的用法。此题中after的意思是“在……之后”;if的意思是“如果”;since的意思是“因为”;unless的意思是“除非”,通过分析后得知“如果”这个答案最贴切,故应选B。此外,句中if引导的状语从句的主语与主句主语一致,且谓语动词为系动词,这说明具体内容被省略。

 

3,Q:The central provinces have floods in some years, and ____

   A, drought in others                   B, droughts are others

   C, while other droughts                D, others in drought

 答案:选A

 解释:句意:中部省份有些年份闹水灾,另一些年份闹旱灾。此句考查代词的指代用法。这里用others指前文提到的years表示对等关系,即floods in some years, and drought in other years而其他答案均不符合这一要求,故选A

 

 4,Q:Do help yourself to some fruit, ____ you ?

     A, can’t     B, don’t     C, wouldn’t     D, won’t

  答案:选D

  解释:句意:你吃点水果吧,好吗?此句考查附加问句的用法。祈使句后面用反意疑问句,形式经常为will you或 won’t you的形式,而其他答案均不符合这一要求,故应选D

 

5,Q:There ____ nothing more for discussion, the meeting came to an end half an hour earlier.

    A, to be     B, to have been     C, being     D, be

  答案:选C

  解释:句意:没有什么别的可讨论了,会议提前半个小时就结束了。此句考查非谓语动词的用法。因为本题后半句是一个完整句子,且句中两部分没有连词,故前半句表示伴随的状态只能使用一个非谓语动词中的分词形式,故应选C

 

6,Q:You ____ Jim anything about it. It was none of his business.

    A, needn’t have told                     B, needn’t tell

    C, mustn’t have told                     D, mustn’t tell

  答案:选A

  解释:句意:你本来没必要告诉杰姆这件事的,这和他一点关系都没有。此句考查情态动词的用法。选项中,needn’t have done的意思是“本来不必做某事却做了”;needn’t do的意思是“现在没必要去做某事”;mustn’t do的意思是“千万不能,一定不能做某事”。另外,C选项中mustn’t have done的形式很少用。通过分析句意可知A最符合,所以选A

 

7,Q:All of us would have enjoyed the party much more if there ____ quite such a crowd of  people there,

    A, weren’t     B, hasn’t been      C, hadn’t been    D, would’t be

   答案:选C

   解释:句意:要是当时没那么多人的话,我们就会在聚会上玩得更高兴了。此句考查虚拟语气的用法。从句中would have enjoyed能看出这里用的是与过去事实相反的虚拟语气,因此从句应该用had+过去分词的形式,故应选C

 

8,Q:Firms that use computers have found that the number of staff ____ quality control can be substantially reduced.

 A, whose       B, as       C, what        D, that

 答案:选D

 解释:句意:使用计算机的公司发现,所需的质量控制人员的数量可以大幅度减少。此句考查定语从句连接词的用法。句中的定语从句用来修饰the number of staff引导定语从句的关系代词指代the number of staff同时该词还在从句中作主语。此外,虽然as也可用作关系代词引导定语从句,但其先行词需用such或the same来修饰。因此,这里这有D符合要求,故选D

 

9,Q:____ at in this way, the present economic situation doesn’t seem so gloomy.

   A, Looking    B, Looked     C, Having looked      D, To look

  答案:选B

  解释:句意:从这个角度来看,现在的经济状况并不暗淡。此句考查非谓语动词逻辑主语的用法。这里后半句是一个完整句子,且前后两部分之间没有连词衔接,因此前半句应该选择非谓语动词形式来作条件状语。这里空白处所填动词的逻辑主要是后半句的主语the present economic situation与look一词为动宾关系,故此处应选择过去分词表示被动的意味,故选B

 

10,Q:She did her work ____ her manager had instructed.

     A, as    B, until    C, when     D, though

   答案:选A

   解释:句意:她按照经理的指示去干活。此句考查连词的用法。选项中,as意为“像,如”;until意为“直到”;when意为“当……时”;though意为“尽管”。这里符合句意的只有A,故选A

 

11, Americans eat __A__ as they actually need every day.

A. twice as much protein    B. twice protein as much twice

C. twice protein as much    D. protein as twice much

解:考查倍数的表达。根据规则,运用统计比较as…as…,表示倍数的词置于第一个as之前,比较的性质与对象谓语两as之间,因此A符合要求。

12, Until then, his family __D__ from him for six months.

A. didn’t hear   B. hasn’t been hearing   C. hasn’t heard   D. hadn’t heard

解:考查过去完成时。根据Until then可以看出主句的行为发生在该时间前,再由表达一段时间的for six months可以断定此处应用过去完成时,所以是D。

 

13, There ought to be less anxiety over the perceived risk of mountain climbing than __A__ in the public mind today.

A. exists   B. exist   C. existing   D. to exist

解析:本题考查than引导的比较状语从句的用法。

 

14, He’s __C__ as a “bellyacher”—he’s always complaining about something.

A. who is known   B. whom is known   C. what is known   D. which is known

解析:what 可作关系代词,表示“···的事物或人”,而who,whom,which都没有此种用法。What在此处构成what is known as ···,表示“所谓···的”,做句子的表语。

 

15, I went there in 1984, and that was the only occasion when I __C__ the journey in exactly two days.

A. must make   B. must have been   C. was able to make   D. could make

解析:本题表示:1984年我去过那儿,那是仅有的一次,我用了足足两天的时间终于完成旅程。A和B的语气与题意不符,be able to与could一般情况下课通用,但当表示“经过努力或克服了困难之后做成了某事”时只能用be able to,所以用C。

 

16, The Clarks haven’t decided yet which hotel __C__.

A. to stay   B. is to stay   C. to stay at   D. is for staying

解析:不定式前可以加疑问词作句子成分。另外stay是不及物动词,必须加at才能接hotel.

 

17, He __A__ unwisely, but he was at least trying to do something helpful.

A. may have acted   B. must have acted   C. should act   D. would act

解析:本题考查情态动词+动词的完成时的用法。根据题意排除C和D,A表示不太肯定的推测,而B表示肯定的推测,符合题意。

 

18, Come and see me whenever __C__.

A. you are convenient   B. you will be convenient

C. it is convenient to you   D. it will be convenient to you

解析:whatever引导的时间状语从句须用一般现在时表将来,因此先排除B和D,另外,convenient一般不用人来作主语,而是常构成be convenient to/for sb.结构,所以选C。

 

19, You __A__ Mark anything. It was none of his business.

A. needn’t have told   B. needn’t tell   C. mustn’t have told   D. mustn’t tell

解析:needn’t have done的意思是“做了本没有必要做的事”。

 

20, He __A__ the 8:20 bus because he didn’t leave home till 8:25.

A. couldn’t have caught   B. ought to have caught 

C. shouldn’t have caught   D. must not have caught

解析:couldn’t have +过去分词,表示对过去已经发生的事实的一种否定猜测,意思是“不可能做了某事”,符合题意。

 

四,感想

    虚拟语气有个很重要的口诀“坚决要命”(建议,决定,要求,命令)这是对于be-型虚拟语气的高度概括,也是老师课堂上给我最大的印象。尤其是对于我们这种懒学生特别有用(因为这样可以省去记一大堆符合这规则的动词,形容词和名词哦)所以说嘛,语法是多么的博大精深,老师的课堂也是不可缺少的呐~~以后继续努力噢!^-^
