表示委婉地提出请求1. Could you please clean your room?
Yes, sure./ Of course./ Certainly./All
right.
2. Could you please do the dishes?
Sorry, I can’t. I have to do my
homework. —Peter, could you please take out the
trash?
—Sure, Mom. —Could you please do the dishes?
—Sorry, I can’t. I have to do my
homework. 重难点点评 在表示请求帮助或请求允许的疑问句中，常用could代替can，以表示礼貌，委婉或不确定的语气，而can则不具备这些语气。这种情况下不能把could看作can的过去式。以上两句中用could是为了表示礼貌的请求。表示请求帮助或请求允许时，除了can, could之外，还可以用may，句子的表达方式也各有不同，可以用不同的方式来表示同一个概念。例： ① Could/Can/May I use your car for a day?
② I wonder if I could use your car for a day?
如同意可以说
Yes/Sure/Certainly/Yes, (do) please. /Of course. (you may/can). /Go ahead, please. /That’s OK/all right;
如果不同意，可以说
I’m sorry you can’t. /I’m really sorry, but I have to use it today.
要避免说No, you can’t. 这样显得很不礼貌。否定回答通常用委婉语气。③ Do you mind if I use your car for a day?
同意可以说
Never mind. /Not at all. 表“不介意”。
不能用Yes. /Sure. /Of course. /Certainly.等。
无论肯定还是否定应答中，要避免使用could，要用can或may。因为应答须用确定的语气。而could在表请求的问句中是为了表示礼貌或委婉语气，用在应答中则成了不确定语气，与情理不符。所以应答中要说Yes, you can. 或Sorry. /No, you can’t. —Could I please use your computer?
—Sorry, I’m going to work on it now. —Well, could I watch TV?
—Yes, you can.Could I/you please …？表示一种有礼貌的请求或提议，其后连接原形动词，比Can you /I…？语气更委婉。类似句型有：Would you like + sth. / to do sth.?
May I + do sth.?
Shall we + do sth.?
Would you mind + sth. /doing sth.? What / How about + sth. /doing sth.? 肯定回答有
Sure. /Of course. / Certainly. /OK. /Great. / Well. / Good idea. / I agree. 等。
否定回答有Sorry… / No, you can’t. 等。 Make up dialogues using the sentences in Grammar Focus with your partner.A: Could you please take the dog for a

2. ___ Could you please pass me the salt?
3. ___ Could I borrow that book?
4. ___ Could you help me do the dishes?
5. ___ Could you lend me some money?PPRRRdacebborrow和lend都可译为“借”，但用法不同。
（1）borrow v. “借，借入；借用”. 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 v. “借出；借给”，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
某物多长时间时，不能用borrow 或lend, 而
要用keep, 意为“保存；保留”。如： You can borrow a book from the library.?
He’s going to lend his bike to Tom.

You mustn’t lend others my pen.? Could you _______ your dictionary to me?
A. borrow B. lend C. keep D. useB4b Fill in the blanks in the conversation. A: I hate to ____ chores.

might, must
可情态可实义的　 need
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。can 和could： 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表示“能够”时与短语be able to同义,但
(1)can只用于一般现在时或过去时，而后者可用于各种时
态。
(2)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.；
(3)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。如：
Can you understand the different kinds of English these people are using?
Two years later, he was able to speak very good Chinese.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: e.g. Could you lend me your dictionary?
Could I use your bike?
3) can和could接动词的完成形式，表示可能已经做某事。
can用在否定和疑问句中, 表示不相信、怀疑等态度。
　 e.g. They can’t have gone out because the light is still
on.以could或would提问时，不能再以could或would作答，而应该用can或will。如：
—Could I borrow your dictionary?
—Yes, of course you can.If we are having a camping trip, what should we do before the trip?DiscussionWhat should we do before the trip?buy some drinksbuy some foodtake a big cloth bring a tenttake an umbrellatake a rubbish bag bring a cameraprepare some programs4c Make a list of things your group needs to do for a
