Grammar 语法精讲一、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，后面只能接动词原形。
2．情态动词没有人称、数的变化，但有些情态动词，如can、will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。 语 法
精 讲二、can和could的用法1．表示“能力”。
(1)can, be able to都可表示“能力”，但can的主语是人或物，be able to的主语是人。
She can/is_able_to sing the song in English.
This machine_can_make you feel comfortable. 语 法
精 讲 (2)can只用于现在式和过去式(could)。be able to可以用于各种时态。
We'll_be_able_to finish the work soon.
I haven't_been_able_to see the film.
(3)could用于表示泛指过去的能力。
I could read when I was four. 语 法
精 讲 语 法
精 讲2．表示“请求、许可”。当表请求时，could不表示时态，只表示委婉的语气(注意在回答中不可用could)。
—Could/Can I have a look at his notebook?
—Yes, you can．/No, you can't. (表许可)
—Could/Can you tell me the way to the theatre?
—It's my pleasure.(表请求)3．表示“惊异、怀疑、不相信”的态度，主要用于感叹句中。
How can_you be so foolish?
4．表示推测，译为“可能”，常用于否定句和疑问句。
Can this news be true?
It can't_be Mary.She has fallen ill.
5．表示客观可能性，意为“有时也会……”。
The temperature here can be 40℃ in summer. 语 法
精 讲1．may和might 用于一般疑问句中表示“许可”，而might 比may更委婉。肯定回答用may/can，否定用mustn't。
—May I use your pencil?
—Yes, you may/can．/No, you mustn't．
2．may和might都可以表示“可能性”， 常用于肯定句，但might暗示的可能性比may更小。 语 法
精 讲三、may和might的用法She may be working now.
Our ancestors might return either to help or to do harm.
注意：could也可以用在肯定句中表猜测，但can不能。
What he said may/might/could be true. 语 法
精 讲 语 法
精 讲四、must和have to的用法1．must用于一般疑问句中，肯定回答用must，否定回答用needn't或don't have to，意为 “不必”。mustn't表示“禁止，不允许” 。
—Must I finish all assignments at a time?
—Yes, you must. /No, you needn't．
You_mustn't get down while the car is still moving. 语 法
精 讲2．表示“必须”的意思时，must 和have to 稍有区别。must着重说明主观看法，have to 强调客观需要。另外，have to 能用于更多时态。
I don't like this TV set.We must buy a new one.
There was no more bus.They had_to walk home.
3．must表示猜测时，意为“准是”“一定”，语气较强，多用于肯定句中，其否定式用can't表示。
You must be the new teacher.
He must be joking.There is nobody here.五、shall，should 和ought to的用法1．在疑问句中shall用于第一、三人称，表示“请求或征求意见”。
Shall I open the window for you？(表征求意见)
Shall he fetch some water for you？(表请求)
2．在陈述句、祈使句等中，shall用于第二、三人称，表示“允诺、警告、命令、决心”等。
You shall do as I say.(表命令) 语 法
精 讲 Tell him that he shall have the book tomorrow. (表允诺)
Nothing shall stop me doing it.(表决心) 3．should常表示“劝告、建议、命令”，也可用ought to。在疑问句中通常用should代替ought to。
Young people should/ought_to learn how to use computers.
Should he go to class right now?
4．should可表义务，意为“应该做”，与ought to同义，但ought to语气稍强。 语 法
精 讲Every citizen ought_to obey law.
You should help him because he is in trouble. 语 法
精 讲 1．will和would表示“意愿、意志”，可用于各种人称。
If you will help me with my English, I will be very happy.
I promised that I would do my best.
2．在疑问句中，will用于第二人称，表示“请求或征求意见”，would的语气则更委婉。
Will you tell him the news as soon as he comes back? 语 法
精 讲六、will和would的用法 Would you please speak again more slowly?
3．will可表习惯、倾向，用于第三人称，表示“常常”之意。如果表示“过去常常”，则用would。
He will sit there hour after hour doing nothing.
During the vacation he would visit me every week.
4．will还可表自然规律。
If the pure water is heated to 100℃， it will boil. 语 法
精 讲 例1You ________park here! It's an emergency exit.
语 法
精 讲例题剖析mustn't 由后面的 “这是一个紧急出口” 可知， 这儿是禁止某人停车， 所以用 mustn't表示 “禁止、不允许”。 例2— ________I take the book out?
—I'm afraid not. 语 法
精 讲May 考查情态动词。表请求可用情态动词 can，may，could，might，表允许用 can，may。句意为： “我可以将这本书带出去吗？” “恐怕不行。”故填表请求的情态动词may。 例3Doctors say that exercise is important for health，but it__________ be regular exercise. 语 法
精 讲must 考查情态动词。can 一般表示 “可能， 能力”； will表示 “意志”； may 表示 “许可， 可能”； must表示 “必须”。 例4You______________ buy a gift，but you can if you want to. 语 法
精 讲don't have to 情态动词 don't have to 意为 “没有必要” , 符合语境。 句意为： “你没有必要买礼物， 但如果你想买的话， 你也可以买。” 例5I have told you the truth.________I keep repeating it? 语 法
精 讲Must 考查情态动词的用法。前半句说“我告诉你事实了”，这里用的是现在完成时，表示过去的动作对现在造成了影响，既然“我”已经说了，“我还必须重复一遍吗？” 例6Just be patient.You ________expect the world to change so soon. 语 法
精 讲can't 考查情态动词。can't在否定句中可以表示推测，意为“不可能”；可以表示能力， 意为“不能够”； 也可以表示“命令， 不允许”， 但是语气比 mustn't 弱， 具有劝慰的意思。 Thanks 课件53张PPT。Unit 1
