Now you ____ stop your car when the traffic lights turn yellow.A.must B.can't C.might
答案选择A项,
A项“必须”,B项“不可能”,C项是“可能”must语气强于might
翻译:现在你必须在黄灯的时候停住你的车.
情态动词must用法如下:
1) 表示“必须”
此时可用于肯定句、否定句或疑问句,用于否定句时,mustn’t的意思是“一定不要”“不能”,而不表示“不必”.如:
Water must be pure if it is to be drunk.水如供饮用必须净化.
Must I finish the work tonight?我必须今晚完成这项工作吗?
Adverbs mustn’t be put between the verb and the object.副词不能放在动词和宾语之间.
must主要表示现在或将来,但在间接引语中也可表过去(=had to).如:
She asked her boss if she must (had to) work overtime.她请示上司她是否要加班.
对于must开头的一般疑问句,若作否定回答,可以用needn’t,不用 mustn’t.如:
“Must I clean all the rooms?” “No,you needn’t.” “这些房间我都得清扫吗?”“不必.”
(2) 表示推测
意为“准是”“一定是”,通常只用于肯定句.若用于否定句或疑问句,则用 can 代之.如:
That can’t be the only way.There must be other ways of solving the problem.那不是解决问题的唯一办法,肯定有另外的办法.
Jane’s light is on.She must be at home.She can’t be out.简的房间里开着灯.她一定在家,不会出去的.
若要谈论过去的情况,必须用“must+have+过去分词”.如:
You must have mistaken my intention.你一定是误会了我的意图.
She must have been very young when she got married.她结婚时一定很年轻.
He must have come this way; here are his footprints.他一定是走这条路来的,这里还有他的脚印呢.
(3) 表示“偏偏”
有时must可表示某事发生得不早不迟,就在某个当紧的时候,多指某些不受欢迎的事情的发生.如:
The car must break down just we were starting our holidays.我们刚刚开始休假,汽车偏偏坏了.
Must you worry her with questions,just when she is busy cooking dinner?她正忙着做饭你干吗偏偏问她问题?
Just when I was busy,the neighbor must come and chatter.正当我忙碌的时候,邻居偏偏过来聊天.
有时还可指主观上的偏执或固执,常可译为“偏”“偏要”.如:
After I gave her my advice,she must go and do the opposite.在我给她出主意之后她偏要反着干.
Must you make so much noise?你就非得弄出这么大的声音吗?
(4) must 与 have to 的区别
两者都表示“必须”,但must 侧重于说话者的主观看法,认为有必要或有义务去做某事;have to 则重于客观需要,含有“不得不”“被迫”之意.如:
Everyone must keep the law.人人都要守法.
The last train has gone.We’ll have to walk home.最后一班车已经开了,我们得走回家了.
从时态方面看,must 只有现在时一种形式(在宾语从句中可以表示过去),而 have to 则有多种时态形式.如(www.hxen.com):
You will have to show your papers at the gate.在大门口你得出示证件.
We have had to postpone the meeting,due to the Chairwoman’s illness.由于女主席生病了,我们不得不推迟开会.
另外,have to 可以有分词、动名词、不定式等形式,而 must 则没有这些形式.如:
It’s annoying to have to get up early on Sundays.星期日必须早起,令人恼火.
You should offer to help without my having to ask.你应该不用我请求就提供帮助.
用于否定句时,must 的否定式 mustn’t 意为“一定不要”“不允许”;而have to的否定式don’t have to 意为“不必”(=needn’t).比较:
You mustn’t tell him about it.你一定不要告诉他这件事.(可能是秘密)
You don’t have to tell him about it.你不必告诉他这件事.(他可能知道了)
can的用法如下:
1.(表示能力、功能)能,会
The classroom can seat thirty students.
这教室能坐三十位学生.
June can drive now.
琼现在会开车了.
2.(表示可能性)可能,可能会
I think the work can be completed ahead of time.
我认为这项工作能提前完成.
3.(表示允许、请求)可以
You can't take the book out of the room.
你不可以将这本书拿出室外.
Can I use your pen?
我可以用一下你的笔吗?
4.(表示命令)必须
If you won't keep quiet you can get out.
你如不保持安静,就请你走.
5.(表示偶然发生的可能性)有时会
It can be quite windy there,especially in spring.
那里有时容易刮风,特别在春季.
6.(表示惊讶)究竟;竟至于
What can it possibly be?
到底那是怎么一回事?
还有名词的意思:1.(食物)罐头
2.金属容器
might的用法如下:
1) 表示允许或请求;表示没有把握的推测;may 放在句首,表示祝愿.
May God bless you!
He might be at home.
注意:might 表示推测时,不表示时态.只是可能性比may 小.
2) 成语:may/might as well,后面接不带to 的不定式,意为不妨.
If that is the case,we may as well try.
不清楚的地方请继续发问!
