情態(tài)動詞用法口訣情態(tài)動詞用處大,可是學生也

 Rain_Sounds 2017-12-09
情態(tài)動詞記憶口訣: 情態(tài)動詞兩要點;動詞原形跟后面,說話語氣較委婉,can表'能力'may'許可',must'責任'或'義務',否定回答'needn't'換;should'應該',would'愿',have to '被迫'表客觀. 注釋:對must構(gòu)成的一般疑問句作否定回答只能用needn't. can的用法 1. 表能力 Can your sister skate / Can you sing / Can you dance 2. 表示可能性 Can you go with us We can go there by bus. 3. 表示同意做某事,意為'允許','可以' You can go now. Can I have a look at your photos 4. 表 推測(主要用于否定句,疑問句) It can't be Jay Zhou. He can't be thinking about something. must的用法 1. 表示按命令,規(guī)定,責任等必須要做的事. You must do all the homework by yourself. You mustn't park your car here. 在回答由must引導的一般疑問句時,如果表示肯定,用must;如果表示否定,要用needn't. -Must I come here tomorrow -Yes, you must. (No, you needn't.) 2. 表示肯定的推測,意為'一定會','一定是',多用于肯定句. It must belong to Karla. He must be happy. You must be joking. must和have to 的區(qū)別是:must表示說話人的主觀意愿,而have to 則表示客觀要求,意為'不得不'. You must tell us what you have seen. He had to walk home because the bus had left. need的用法 need除了可用作行為動詞外,還可用作情態(tài)動詞,作為情態(tài)動詞使用時,多用于疑問句和否定句,后面直接跟動詞原形,作為行為動詞時,后面跟帶to的動詞不定式. 他需要現(xiàn)在去看醫(yī)生嗎 Does he need to see a doctor now Need he see a doctor now need作為情態(tài)動詞,意為'需要',無時態(tài)和人稱的變化. They needn't hand in their homework now. Need I stay with you (肯定回答為:Yes, you must. 否定回答用No, you needn't.) may的用法 1. 表示'可以',用以詢問或說明可否做某事. May I use your pencil You may come here tomorrow. (在回答由may引導的問題時,常以Yes, please或certainly來表示允許或同意,而用please don't 或no, you mustn't來表示不允許和反對.) 2. 用于表推測某事可能發(fā)生或某情況可能存在,意為'可能',一般不用于疑問句. It may rain this afternoon. She may still be in the classroom.
