Be a good boy! 要做一个好孩子! Be careful! = Look out! = T

11、ake care! 小心 / 当心！（3）Let + 宾语 + 动词原形 + 其它成分 Let me help you. 让我来帮你。 Lets go to school together. 咱们一起上学去吧。2. 否定的祈使句(1) Dont + 动词原形 Dont stand up. 别站起来。 Dont be careless. 别粗心。 Dont let them play with fire. 别让他们玩火。(2) Let型的否定式有两种:“Dont + let + 宾语 + 动词原形 + 其它成分”与“Let + 宾语 + not + 动词原形 + 其它成分”。 Dont let

12、him go. / Let him not go. 别让他走。 Let them not play with fire. 别让他们玩火。(3) no开头,用来表示禁止性的祈使句。 No smoking! 禁止吸烟!No fishing! 禁止钓鱼!3. 祈使句的强调形式，通常在肯定祈使句式前加上助动词Do。 例如：Do shut up! 快住口！ 4. 祈使句的回答 祈使句的动作通常是表示将来发生的动作，所以回答祈使句时，一般用 will或wont。 在回答具有否定意义的祈使句时，要注意两点： 1) 形式一致(即Yes与will保持一致；No与wont保持一致) 2) 意思相反(即Yes是 “

13、不”的意思；No是 “是”的意思)。 在回答时，要注意分析上下文语境中所提供的条件。如：- Dont go out, please. Its raining heavily outside. 请不要出去。外面雨下得很大。 - Yes, I will. I have to meet my brother at the airport. 不行，我得去机场接我弟弟。 （二）易错点讲解1、放句首时，要注意Dont后面要用动词原形；2、当人称后面有标点符号时，要注意是用祈使句还是用三单。如：Lucy, dont be late again. Lucy, a 17-year-old girl, is no

14、t late again.3、祈使句与or的搭配， 如：Hands up, or well shoot. 【趁热打铁】1. _ late again, Bill! A. Dont to be B. Dont be C. Not be D. Be not2. _ cross the road until the traffic lights turn green. A. Not B.

18、t some sleep你最好去睡一会儿。We had better go before it rains.我们最好在下雨前就去。2. had better如何构成否定式与疑问式构成否定式时，通常将not置于had better之后(而不是had之后)；而构成疑问式时，则通常将had(而不是had better)置于主语之前。如：Id better not disturb him我最好别去打扰他。What had we better do? 我们最好怎么办? 【注】在否定疑问句或反意疑问句中可将not与had连用。如：Hadnt we better go now? 我们是不是现在就去呢? 3.

22、need, teach, prepare,等，常接动词不定式作宾语。当动词不定式作宾语时，如果后接宾语补足语，常用it作形式宾语，而把真正的宾语放在宾语补足语之后。应注意有些动词后面可接不定式作宾语，也可接动名词作宾语，但所表达的意义不同。常见的有：（1）stop to do sth.停止正在做的事，去做另一件事；stop doing sth. .停止正在做的事（2）go on to do sth. 做完一件事后，继续做另一件事；go on doing sth.继续做同一件事（3）remember/forget to do sth.记住忘记去做某事；remember/forget doing
