19、两种，除在句首+dont外还可以在 动词原形前即宾语后+not。 此外，在公公场合的提示语中，一般用No+名词/动词-ing形式用来表示禁止的祈使句。如：No photos! No fishing!反义疑问句：1、祈使句为肯定句式时，若其翻译疑问句表示请求时，通常用will you;表示邀请、劝说时，用wont you.如 Be sure to ring me, will you? 记得打电话给我，好吗？ Come to have dinner with us this evening, wont you?今天晚上和我们一起吃饭，好吗？2、祈使句为否定句时，其反义疑问句通常只用 will yo

20、u.如： Dont smoke in the meeting room, will you? 不要在会议室抽烟，好吗？3、Let开头的祈使句构成反义疑问句时，除Lets用shall we外，其他均用 will you.如： Lets take a break，shall we? 我们休息一下，好吗？ Let the boy go first, will you? 让那个男孩先走，好吗？祈使句的回答 祈使句的动作通常表示将来发生的动作，所以回答时一般用will或wont.回答具有否定意义的祈使句时，要注意两点：一是：形式一致，即Yes与will保持一致，No与wont保持一致；二是：意义相反，即

21、Yes是 不 的意思，No是 是 的意思。要根据语境来判断-Dont go out, please! Its raining heavily outside.-Yes, I will. I have to meet my brother at the airport.2、情态动词may和might情态动词口诀:can不肯，即：表推测时can (could) 一般不用于肯定句；may不问，即：表推测时may (might)一 般不用于疑问句；must肯定不否问，即：表推测时must一般 仅用于肯定句，不用于否定句和疑问句。情态动词may和might 表示可能性 可能，也许Might1)表过去的“

22、可能”和“允许”多用于间接引语。She said that he might take her dictionary.2)表现在的“可能”，其可能性要比may小。Electric irons could be dangerous; they might give you a severe shock.电熨斗会有危险，它可能电着人。3)may (might) + have +done 表示对过去发生行为的推测，含有“想必”、“也许是”的意思。It may have been true. may 1)表示请求、可以、允许。You may drive the tractor. 2)当回答由may 引起的问题时，否定答语要用must not,表示“不许可”、“不应该”、“不行”。May I come in? No, you mustnt.3) may /might 推测性用法 可能He may be right.注意:1）might可能性比may要小，两
