祈使句（Imperative Sentences）
祈使句一般用来表示请求、命令、劝说、号召、警告等。祈使句的主语一般是第二人称yu，但往往省略。祈使句的肯定式以动词原形开头，否定式在动词原形前加dn't。
e.g. Just g alng this street and turn left. Be careful when yu crss the street. Practise the guitar every day. Dn't be late fr class. Dn't fight.

祈使句中的动词原型，不需要变换形式。
情态动词后用动词原型。
情态动词（Mdal Verbs）
情态动词表示说话人的语气和情态，如请求、许可、意愿、可能等。一般没有人称和数的变化。
情态动词本身不能单独作谓语，必须和动词原形连用。
情态动词的否定式一般是在其后加nt构成，一般疑问句通常将它提到句首。
情态动词的肯定式一般不重读。
1. 表示能力（七上Unit 5已经学习）
e.g. I can run fast, but I can’t swim.
2. 表示许可（本单元重点）
e.g. We can play basketball at the weekend. Students can’t run in the hallways. Can we bring ur phnes t class?
1. 表示“必须”（七上Unit 5已经学习），否定形式mustn’t 表示“禁止”
e.g. Dn’t arrive late fr class. We must be n time. Students mustn’t use their phnes at schl.
2. 以must开头的一般疑问句，肯定回答用must，否定回答 用needn’t 或者dn’t have t， 表示“不必要”
e.g. —Must I clean the classrm nw? —Yes, yu must./N, yu needn’t/dn’t have t.
情态动词 have t
表示“不得不；必须”,在表示“必须”时，与must意义接近，有时可互换。
e.g. We have t be quiet in the library. She has t d her hmewrk first when she gets hme. We have t/must fllw the rules.
1. must表示说话人的主观看法，语气较为强烈，have t则 强调客观需要。
must与have t区别
e.g. We must hurry. I dn’t want t miss the begining f the shw. We have t hurry. The train is leaving in 5 minutes.
2. 它们的否定式含义大不相同。mustn’t表示 “不准；禁止”， dn’t have t表示“不必”。
e.g. Yu mustn't talk t yur mther like that. Yu dn't have t cme if yu dn't want t.
3. must没有人称和数的变化，而have t有人称和数的变化。
e.g. I / We / Yu / They 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 five 'clck.
