核心考点八情态动词与虚拟语气
——使表达得体、含蓄
1．He ________ fatter but he eats too little.
A．would become B．would have become
C．must become D．must have become
解析根据语意知道我们可以在but he eats too little前加上一个省去的条件状语从句if he ate much，由此可知是与现在时相反所以主句用would become。

答案 A
2．He ________ if he works hard for the people.
A．shall praise B．shall be praised
C．will praise D．will be praised
解析句意：如果他为人民努力工作，他会受到表扬。

说话人希望他受到表扬，而will 表示的是句子的主语的意愿，那样意思就是“他愿意受到表扬”，显然不对。

shall用于第三人称可表示说话人对某人所持有的主观立场和坚定的信念。

答案 B
3．There was a lot of fun at yesterday's party.You ________ come，but why didn't you?
A．must have B．should
C．need have D．ought to have
解析该空含你本来应来但实际未来之意，应填ought to have。

答案 D
4．I was really anxious about you.You ________ home without a word.
A．mustn't leave B．shouldn't have left
C．couldn't have left D．needn't leave
解析该空含你本不应该一句话不说就离开家但实际已这么做之意，所以应填shouldn't have left。

答案 B
5．—Must I go there right now?
—No，you ________.You ________ go there before supper.
A．mustn't；need B．needn't；may
C．can't；need D．won't；can
解析Must I．..？肯定回答用Yes，you must.否定回答是No，you needn't或No，you don't have to，不能用mustn't，因为mustn't表示“不许；不准；禁止”，本题后半部用may表示允许。

答案 B
6．—Could I borrow your dictionary?
—Yes，of course you ________.
A．could B．will C．can D．might
解析本题中的could也表示请求(而非表示过去时)，语气委婉，主要用于疑问句，不可用于肯定句，答语应该用can(即could不能用于现在时态的简略答语中)。

答案 C
7．—Are you coming to Jeff's party?
—I'm not sure.I ________ go to the concert instead.
A．must B．would C．should D．might
解析根据I'm not sure判断，表示说话者不确定，有可能去音乐会。

might表示“可能”；must表示“必须，一定”；would表示“将，愿意”；should表示“应该”。

答案 D
8．Mr.Bush is on time for everything.How ________ it be that he was late for the opening ceremony.
A．can B．should C．may D．must
解析can表示可能性的推测，常用于疑问句或否定句中；may表“可能性”常用于肯定句或否定句中，must常用于肯定句中表推测，“一定……”的意思。

注意：can not 表示“不可能”，而may not表示“或许不……可能不……”，两者语气上有区别。

答案 A
9．My sister met him at the Grand Theatre yesterday afternoon，so he ________ your lecture.
A．couldn't have attended B．needn't have attended
C．mustn't have attended D．shouldn't have attended
解析“情态动词＋完成式”有各自的含义。

must have done表示对过去事情的肯定推测，多用于肯定句中；needn't have done表示过去本不必做的事情；shouldn't have done 表示过去做了不该做的事情；can't(couldn't)have done表示对过去的否定性推测，意为“不可能”。

所提供的情境My sister met him at the Grand表示他不可能参加讲座。

答案 A
10．He hesitated for a moment before kicking the ball，otherwise he ________ a goal.
A．had scored B．scored
C．would score D．would have scored
解析根据otherwise可以判断出要用虚拟语气表示过去发生的事要用would have scored。

答案 D
11．Oh，I'm not feeling well in the stomach.I ________ so much fried chicken just now.
A．shouldn't eat B．mustn't have eaten
C．shouldn't have eaten D．mustn't eaten
解析just now是表示过去的时间状语。

情态动词在表示过去发生的事时，必须用“情态动词＋have＋过去分词的形式”。

所以只能在选项B或C中确定答案。

mustn't have eaten是一个错误选项，因为“mustn't＋动词”表示“禁止”，不表示判断或推测。

答案 C
12．A left－luggage office is a place where bags ________ be left for a short time，especially at a railway station.
A．should B．can C．must D．will
解析should应该；can能够，会；must必须；will愿意。

句意：行李寄存处是能够暂时存放行李的地方，尤其是在火车站。

此处用can表示可以、能够。

答案 B
13．Keep up good state of mind even if you ________ fail plenty of times.
A．must B．will C．can D．should
解析考查should的用法。

should用在if或even if引导的表示条件的从句中，表示一件事听起来可能性很小，但也不是完全没有可能，相当于“万一”的意思，从句谓语由should加动词原形构成，主句不一定用虚拟语气。

答案 D
14．—It's the office！So you ________ know eating is not allowed here.
—Oh，sorry.
A．must B．will C．may D．need
解析从前后文可知，此处是一种很肯定的推测，因此选A。

答案 A
15．But for the help of my English teacher，I ________ the first prize in the English Writing Competition.
A．would not win B．would not have won
C．would win D．would have won
解析此处虚拟语气表示与过去事实相反，句子谓语动词用would/should/could/might ＋have done结构，根据句意要用否定含义，故选B。

本句的条件是由介词短语(but for)表达的。

答案 B
16．There ________ be any difficulty about passing the road test since you have practised a lot in the driving school.
A．mustn't B．shan't C．shouldn't D．needn't
解析根据经验或惯例对某一情况进行推测，用should或ought to，常译成“按理应该……”或“可能会……”。

shouldn't是其否定形式。

答案 C
17．—Is John coming by train.
—He should，but he ________ not.He likes driving his car.
A．must B．can C．need D．may
解析come，go，leave，start等趋向动词的进行时表示将来时，所以答语是对这一将来动作做出的推断。

may not“可能不，不一定”，根据he likes driving his car可以看出John可能乘火车来，也可能自己开车来。

may not正好符合这一语境。

must not“不准”；cannot“不可能”；need not“不必”。

答案 D
18．It is hard for me to imagine what I would be doing today if I ________ in love，at the age of seven，with the Melinda Cox Library in my hometown.
A．wouldn't have fallen B．had not fallen
C．should fall D．were to fall
解析根据句意和I would be doing可以判断这是虚拟语气。

at the age of seven 是表示过去的时间状语，if从句中的谓语要用had not fallen，表示对过去情况的假设。

答案 B
19．You can't imagine that a well－behaved gentleman ________ be so rude to a lady.
A．might B．need C．should D．would
解析should用于表示感情，意向等句中的that从句，表示“竟然……，居然……”，出乎意料。

答案 C
20．What would have happened ________，as far as up to the river bank.
A．Bob had walked farther
B．if Bob should walk farther
C．had Bob walked farther
D．if Bob walked farther
解析因为主句的谓语动词用了would have happened，所以从句的谓语动词要用过去完成时。

在虚拟语气中，如果条件状语从句中的if省略，该句要倒装。

答案 C。
