寒假作业 02 情态动词 could 的用法
情态动词could表请求与许可
1. 核心用法——表委婉请求
基本句型：向他人提出礼貌请求时，核心结构为“Could you (please) + 动词原形 + 其他？”，语气比
“can”更柔和，适用于陌生人、长辈或需要体现礼貌的场景。例如“Could you please pass me the
plate？”（你能把盘子递给我吗？）、“Could you help me carry the heavy box？”（你能帮我搬这个重箱
子吗？）。
否定形式：请求对方不要做某事时，需用“Could you please not + 动词原形 + 其他？”，如“Could you
please not make noise in the classroom？”（你能别在教室里出声吗？）、“Could you please not forget to
bring your textbook？”（你能别忘记带课本吗？）。
2. 核心用法——表许可与回应
请求自己做某事：想获得允许做某事时，用“Could I + 动词原形 + 其他？”，例如“Could I use your
umbrella？”（我能用你的伞吗？）。回应时，同意常用“Sure./Of course./No problem.”，拒绝可用“Sorry,
you can’t.”，需注意回应不用“Could I”，因“could”仅表委婉，不表过去时态。
回应他人请求：面对“Could you...”的请求，同意用“Certainly./Yes, I can.”，如对方问“Could you please
open the window？”（你能开下窗户吗？），可回答“Certainly.”（当然可以）。
3. 易混辨析——could vs. can
语气差异：“could”更委婉礼貌，适合正式或陌生场景，比如向老师求助说“Could you please help me with
my homework？”（您能帮我辅导作业吗？）；“can”较随意，适合熟人场景，如对朋友说“Can you help
me？”（你能帮我一下吗？）。
用法侧重：“could”仅用于“委婉请求”，不表“能力”；“can”可表“请求”或“能力”，如“I can
swim.”（我会游泳），此处不能用“could”替换。
【易错提醒】1.对提出请求或征询许可的句型做否定回答时，通常以sorry或I’m sorry开头。
Eg.—Could you help me with my English now? 你现在能帮我学英语吗？
—I’m sorry, but I have a football match ten minutes later. 抱歉，我十分钟后要参加一场足球赛。
2.如果问句中使用could，回答时要用can或can’t，不能用could或couldn’t。
Eg.—Could I use your bike? 我能用一下你的自行车吗？
—Sure, you can. 当然可以。

Friends can be similar or different, but what really matters is mutual respect. My best friend Anna and I are
very different. She is outgoing and loves performing on stage, while I am shy and prefer reading in my 25
(spare) time. However, we 26 (have) a lot in common too—we both love music and animals.
Anna often encourages me 27 (join) her in school activities, and I help her with her math. Last
month, we 28 (take) part in a talent show together. She played the flute, and I sang a song. Although we
were nervous at first, we 29 (final) won the second prize.
What I love most about Anna is her 30 (honest). She always tells me the truth, even if it’s hard to
hear. This helps me 31 (become) a better person. In return, I support her 32 she faces
challenges.
Differences between friends can be a good thing. They make our friendship 33 (interest) and teach
us to appreciate each other’s strengths. So, whether friends are similar 34 different, the key is to accept
and cherish each other.

Not only adults but also teenagers have problems in their life. Here is a survey showing the main problems
of teenagers.
They feel stressed because they have too much homework to do both at school and at home. They have lots
of exams to take. And parents usually send them to different classes on weekends. (3)They don’t have time to do
what they are interested in.
Now more and more teenagers are getting short-sighted (近视的). They often read in bed or keep reading for
a long time without having a rest. Some of them are crazy about playing computer games. Some spend too much
time watching TV.
(4)Another serious problem among teenagers is that many of them are becoming fat. They eat too much junk
food, but they take little exercise.
I think teenagers should think of ways to deal with the problems. They should make a plan for study and
hobbies. What’s more, they should also find time to relax as much as possible.
