● To learn to use English Imperatives
■Procedures
Step 1: Learning about Imperatives
We use imperatives for different reasons, such as telling people what to do, giving
instructions and advice, making recommendations and suggestions, and for making
offers.
Come in and sit down, please.
Don’t open the door – it’s cold.
Put the books on the desk and open the window.
Don’t ask me – I don’t know.
See the lawyer – it’s the best thing.
Have a bit more water.
▲Emphatic imperative: do + imperative
Do come next Monday.
Do be a bit braver.
Do forgive me - I didn’t mean to be harm.
▲Passive imperative: get + past participle
Get vaccinated as soon as you can.
▲Do(n’t) be
Don’t be silly!
Do be quiet!
▲Subject with imperative
Mary come here - everybody else stay where you are.
Somebody answer the phone.
Nobody move.
Relax everybody.
▲You before an imperative
You just sit down and relax for a bit.
You take your hands off me!
▲Question tags
Give me a hand, will you?
Sit down, won’t you?
Get me something to drink, can you?
Be quiet, can’t you?
Don’t tell anybody, will you?
▲Word order : always and never put before imperatives

一、重点考查”祈使句 + and / or...”句型
—English has a large vocabulary, hasn’t it?
—Yes. ______ more words and expressions and you will find it easier to read
and communicate.
A. Know B. Knowing C. To know D. Known
答案及简析:答语中的and是破解此题的关键。and属并列连词,用来连接并列成分。与and
后的句子相一致,其前亦应是一个句子。因此,本题正确答案为A,构成祈使句。
复习对策:
把握”祈使句 + and / or...”句型的表意功能:
1. 祈使句表示条件,and后的句子表示结果。
Lose one hour in the morning ______ you will be looking for it the rest of the day.
A. but B. and C. or D. so
2. 祈使句表示要求,or后的句子表示相反行为引起的结果。
Follow your doctor’s advice, ______ your cough will get worse.
A. or B. and C. then D. so
答案: 1-2 BA
二、在特定语境中考查对祈使句的识别
1. 考查祈使动词与非谓语动词的功能区别
—What should I do with this passage?
—______ the main idea of each paragraph.
A. Finding out B. Found out C. Find out D. To find out
答案及简析:破解此题的关键在于对上文语境的理解。题中what引导的问句是为征询建议,
其答语应该是表示说话人的建议。四个选项中只有C能构成祈使句表示建议,因此本题正确
答案为C。
复习对策:
掌握祈使动词与非谓语动词的功能区别:祈使动词构成祈使句,表示要求做某事或不做某事;
而非谓语动词位于句首时主要用作状语(表示时间、原因、条件、目的等),或承接上文作

主语或宾语。
2. 考查带主语的祈使句
—Sorry, Joe. I didn’t mean to...
—Don’t call me “Joe”. I’m Mr Parker to you, and ______ you forget it!
A. do B. didn’t C. did D. don’t
答案及简析:空格后的you仅为加强语气,不影响句法结构。因此,本题正确答案为D,构
成否定形式的祈使句。
复习对策:
克服思维定势,牢记带主语的祈使句的特点:祈使句带主语表示加强语气,或用以指明建议
或警告的对象。其主语可以是you,也可以是someone或everyone。但不管主语是复数还是
单数,谓语动词一定是动词原形。如:Someone help Tom. 你们得有人帮汤姆。
三、考查祈使句的反意疑问句
—Alice, you feed the bird today, ______?
—But I fed it yesterday.
A. do you B. will you C. didn’t you D. don’t you
答案及简析:破解此题的关键首先在于对空格前句子类型的判断。题干的第一句话并非陈述
句,而是祈使句。正确答案为B。如套用反意疑问句”前肯定,后否定”的规则选定D,则
正中拟题人所设”圈套”。
复习对策:
认识祈使句,并熟记祈使句与其反意疑问句的对应规则:
肯定形式的祈使句 + will you?
否定形式的祈使句 + will you?
特殊情况:Let’s..., shall we?
四、考查祈使句的应答语
① —Write to me when you get home.
—______.
A. I must B. I should C. I will D. I can
② —Don't forget to come to my birthday party tomorrow.
—______.
A. I don’t B. I won’t C. I can’t D. I haven’t
答案及简析:祈使动词表示的动作往往是尚未发生的动作,常可用will来回答,既可表示
将来,又可表示意愿。因此,两题答案分别为C、B,表示愿意接受对方的要求。
复习对策:
对祈使句的应答灵活多样,并无固定模式,应根据英语习惯具体对待。例如,回答let型祈
使句,常可用All right. / OK. / Yes, let’s... / A good idea.等表示赞同,用Sorry...
/ I’m afraid... 等表示不赞成,请同学们注意积累。
