在系动词be、助动词be,have /has /had,will,shall,would,should和情态动词后加not(n't)。若句中没有这些词,则根据谓语动词的原形、第三人称动词形式或过去式而分别在其前面加do not(don't), does not(doesn't)或did not(didn't),并将第三人称动词或过去式改为原形。如: He)用含否定意义的词(如:never,nothing,nobody,none,neither, little,few等 will write t①always /ever→never,and→or。如: He was always late for school last term.→He was never late for school last term. they have ever read the book.→They have never read the book. He can speak Chinese and English.→He can't speak Chinese or English. ②too→not...either,already→not...yet。如: He goes to school by bike,too.→He doesn't go to school by bike, either. He has already finished the work.→He hasn't finished the work yet. ③all→none,both→neither,both...and→neither...nor,此时,谓语动词仍用肯定形式,但当neither作主语,谓语动词用单数形式;neither...nor...连接两个主语时,谓语动词应和nor后面的主语保持一致。如: He knows all of the workers here.→He knows none of the workers here. Both of the twins are from England.→Neither of the twins is from England. Both Emma and John have gone to Tokyo.→Neither Emma nor John has gone to Tokyo. 3)当think,believe,suppose等动词后面跟宾语从句时,通常用否定主句谓语动词来达到否定从句谓语动词的目的。如: I think they can come tonight.→I don't think they can come tonight. 4)当must表示推测,表示“一定、肯定”的含义时,否定句应用 can't。如: He must be in the room.→He can't be in the room.he book in two months.→He won't write the book in two months热心网友 时间:2023-08-20 00:28
