什么是祈使句(Imperatives)？
● 用于表达命令、请求、劝告、警告、禁止等 的句子叫祈使句。● 祈使句因对象（即主语）是第二人称， 所以通常省略。● 祈使句为动词原形开头（N型除外）。● 祈使句有D型、Be型、Let型、N型。
Read the sentences. D the verbs in bld need t change frms? Why?
What abut these?
● 情态动词不能单独使用，后面需加动词原形。● 情态动词没有人称和数的变化(have t除外)。● 情态动词否定直接在后面加nt (have t除外， have t的否定形式是nt have t)。
情态动词can表示允许：
Yu can play basketball at the weekend.We can’t run in the hallways.Yu can’t litter.We can’t eat in class.
情态动词can表示请求：
Can yu help me with my Chinese?Can we bring ur phnes t class? N, we can’t.Can we eat snacks in class?Can I pen the dr?Yes, yu can.
must & mustn’t
must表示“必须”，例如：We must keep them in ur lckers.Yu must read a bk befre yu watch TV.mustn’t表示“不准；禁止”Yu mustn’t litter.
情态动词have t：
have t表示“不得不，必须”。例如：We have t be quiet in the library.She has t d her hmewrk first when she gets hme.We have t eat in the dinning hall.
情态动词must与have t：
have t表示“必须”时，与must意义很接近，有时可与must互换。例如：We have t/ must fllw the rules.但是它们也有所不同。
must和have t的不同：
1. We must hurry. I dn’t want t miss the beginning f the shw. We have t hurry. The train is leaving in five minutes.
must 通常表示的是说话人的主观看法，语气比较强烈；have t往往强调客观需要。
2. Yu mustn’t talk t yur mther like that. Yu dn’t have t cme if yu dn’t want t.
它们的否定式含义大不相同。mustn’t表示“不准、禁止”，而dn’t have t 表示“不必”。
3. I/We/Yu/They/He must d smething abut it. I have t finish my wrk tday. She has t wrk late tday. They have t get t the statin befre 5 ’clck.
must没有人称和数的变化；而have t有人称和数的变化。
