千萬別” “禁止,不許”.You mustn’t play with fire. 你不許玩火。(3)對must引導(dǎo)的疑問句, 肯定回答為must,否定回答為needn’t 或don’t have to —Must I finish my homework ? 我現(xiàn)在必須完成作業(yè)嗎?—No, you needn’,你不必。The light is on, so he must be at home ,他現(xiàn)在肯定在家。She must have seen the film before,hasn’t she? (注意反意疑問句的后半部分)You must have met uncle Wang in the shop yesterday,didn’t you? (注意反意疑問句的后半部分)5. need的用法:(1).need表示需要、必須,主要用于否定句和疑問句中,其否定形式為needn’t,意為“沒有必要,不必”?!狽eed I stay here any longer? 我還有必要留在這兒嗎?—Yes, you must .是的。(2).need還可以作實(shí)義動詞,此時有人稱、數(shù)和時態(tài)的變化,如果是人作主語后邊多接動詞不定式。He needs to learn more about the 。.The door needs painting. = The door needs to be 。6. dare的用法:dare意為“敢、敢于”,用法近似于need,有兩種詞性:(1)dare作為情態(tài)動詞,多用于否定句、疑問句或條件句中,無第三人稱單數(shù)形式,只有一般現(xiàn)在時和一般過去時。He doesn’t dare to break his 。Do you dare tell her what I said? 你敢告訴她我說的話嗎?I didn’t dare look at him. 我不敢看他。(1).用“Let39。Let39。What about/How about a drink?

He is going to die. He will be twenty years old.③. be going to含有“計(jì)劃,準(zhǔn)備”的意思,而will則沒有這個意思,She is going to lend us her book.He will be here in half an hour.④.在有條件從句的主句中,一般不用be going to,而多用will, If any beasts es at you, I39。We had better go 。考點(diǎn)二:含有情態(tài)動詞的疑問句的回答:1. 對may引出的問句,可以有下列回答方式:Yes, you may. | 、 Yes, of course. 、 Yes, certainly. 、 Sure .
