情态动词用法
【探究·导学】
只作情态动词的 can / could, may /
might, ought to, must
可情态可实义的 need, dare
可情态可助动词的 shall / should, will /
would
相当于情态动词的 have to, used to
情态动词的语法特征
1) 情态动词不能单独做谓语, 除ought和have外, 后面只能接不带to的不定式。
2) 情态动词没有人称, 数的变化, 但有些情态动词, 如can、will也有一般式和过去式的变化。
3) 情态动词的“时态”形式并不是时间区别的主要标志, 不少情况下, 情态动词的现在式形式和过去式形式都可用来表示现在时间、过去时间和将来时间。
1) can的主要用法是：
A. 表示体力或脑力的能力：
e.g. The girl can dance very well.
B. 表示说话的推测﹑事物的可能性等:
e.g. Can the news be true
C. 在口语中, can可以表示请求或允许:
e.g. Can I sit here
can 和could：
can表示“能够”时与短语be able to同义，但can只用于一般现在时或过去时，而后者可用于各种时态。另外，can表示个人有某种能力，而be able to表示某人通过努力、克服困难做成某事，相当于succeed in doing sth.；叙述过去事实时，最好用was / were able to，因为could只表示过去具有某种能力。
2) could的主要用法是：
A. could 是can的过去式, 表示与过去 有关的能力和推测:
e.g. We all knew that the young man
couldn’t be a doctor.
B. could可以代替can表示请求, 但语气较can客气、委婉:
情态动词用法小结
1. 情态动词不能表示正在发生或已经发生的事情, 只表示期待或估计某事的发生。
2. 情态动词除ought 和have 外, 后面只能接不带to 的不定式。
3. 情态动词没有人称，数的变化，即情态动词第三人称单数不加-s。
4. 情态动词没有非谓语形式，即没有不定式、分词等形式。
could与can的区别
could与can都是情态动词, could是can的过去式。二者都可用于表示请求, 但是用法稍有不同。
can 表示一般性的请求，语气随便, 常用于
熟人之间或长辈对晚辈, 上级对下级的
场合。
e.g. Can you tell us your story, Tony
Tony，你能给我们讲讲你的故事吗？
could表示有礼貌的请求，语气委婉，
常用于非熟人之间或晚辈对长辈，下级
对上级的场合。比如：
--Could you tell us if it snows in winter in
Australia
--Sure.
--请告诉我们, 澳大利亚冬天下雪吗
--当然可以。
注意：1. 提出委婉的请求在回答中不可用could。
A: Could I have the television on
B: Yes, you can. / No, you can’t.
2. 在否定、疑问句中表示推测或怀疑用couldn’t。
He couldn’t be a bad man.
他不大可能是坏人。
may和might
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。
1. 两词都是 “必须”的意思, have
to 表示客观的需要, must 表示
说话人主观上的看法, 既主观
上的必要。
have to和must
My brother was very ill, so I had to
call the doctor in the middle of the night.
我弟弟病得很厉害，我只得半夜里
把医生请来。(客观上需要做这件事)
He said that they must work hard.
他说他们必须努力工作。
(主观上要做这件事)
2. have to 有人称、数、时态的变化,而must只有一种形式。但must 可用于间接引语中表示过去的必要或义务。
He had to look after his sister yesterday.
3. 在否定结构中: don’t have to 表示 “不必”, mustn’t 表示“禁止”。
You don’t have to tell him about it. 你不一定要把此事告诉他。
You mustn’t tell him about it. 你一定不要把这件事告诉他。
2. You watch TV all the time and ...
all the time（在该段时间内）一直，一向；时时刻刻；每时每刻
e.g. I do this all the time.
我一直是这么做的。
This happens all the time.
这种情况是时常发生的。
3. I’m just as tired as you are!
as ... as 意为 “和 ……一样” ，表示同级的比较。使用时要注意第一个as为副词，第二个as为连词。其基本结构为：as + adj./ adv. + as。
4. For one week, she did not do any housework and neither did I.
neither 用作副词，作“也不”解释，放在句首表示前面否定的内容也适用于另一个人或物，句子须用部分倒装。此时也可用nor替换 neither。
neither… nor… 意为“既不……也不……”，连接两个并列主语时，谓语动词的数要与邻近它的主语的数一致
both… and… 意为“既……也……；两者都……”，连接并列成分。连接并列主语时，谓语动词用复数
either… or… 意为“或者……或者……（二者任选其一）”
5. the minute =as soon as
一……就……, 引导时间状语从句。
这个短语比较常用，口语和书面语都可以。它的特点是，在句子中的位置比较灵活，而且可以用于各种时态。
borrow和lend都可译为“借”，但用法不同。
（1）borrow “借，借入；借用”，从主语的角度讲，指“借入”或“借用他人的东西供自己使用”。常用结构为：borrow sth. from sb. 或borrow one’s sth. 意为“向某人借某物”。
borrow / lend
（2）lend “借出；借给”，从主语的角度讲，表示把自己的东西“借出”给别人使用。常用结构为：lend sb. sth. 或lend sth. to sb. 意为“借给某人某物”。
（3）borrow和lend均为非延续性动词，若表达借某物多长时间，不能用borrow 或lend, 而要用keep, 意为“保存；保留”。
表示对对方提出请求，语气委婉，显得有礼貌。
肯定回答：Yes, I can. / Yes, sure / Yes, of course. / No, problem. / With pleasure.
否定回答：Sorry, I can’t. I have to… / Certainly not. / No, I’m afraid I can’t.
