need后面为什么要加to
逄珊震4328needn't和don't need to分别用在什么时候 -
杜泽阳13467003453 ______ 是这样的,needn't do 和 don't need to do 两者有些差别. 就像needn't have done 和 didn't need to do 一样. 从用法上,前者是情态动词,后者是实义动词. 从意义上,前者暗示已经做了,有“本不需要”的意思,后者暗示还没有做,就是纯粹地“不需要”. 如:You needn't do the housework.(说话时你已经做了家务) You don't need to do the housework.(说话时你尚未做家务)
逄珊震4328need做特殊限定动词使用时,为甚麽后面要加不带to的动词不定式再举一些这样的例句 -
杜泽阳13467003453 ______[答案] 什么叫特殊限定动词? 那叫情态动词 情态动词+动词原型(所谓不带to动词不定式) 这个是英语语法强制规定固定规则的 就和is + 动词ing表示进行时一样 没有为什么,规定就这样. 意思是为:需要做什么, 比如:you need not know the word.你不需...
逄珊震4328need的用法 -
杜泽阳13467003453 ______ 初中情态动词其实是一个重点,或者说似乎一直是重点.至少在我们这里(人教版).need可以作为实意动词,是及物动词,后加动词不定式to do或名词.否定形式常考与情态动词的区别,要区分开,实意动词否定形式是don't need to do不需...
逄珊震4328don't need 和need not 怎么用?后面该加怎样的动词形式 -
杜泽阳13467003453 ______ 判断need做哪种动词,你可以看后面的动词形式. need做实意动词:need to do,否定在前面+don't或者doesn't need做情态动词:need do(动词原形),否定在后面+not 考试的时候可以根据后面的动词形式,即是动词原形还是不定式to do,来判断前面用don't或者doesn't还是not否定,也可以根据前面否定形式,来判断后面用to do还是动词原形
逄珊震4328Needn't + do还是+ to do -
杜泽阳13467003453 ______ needn't do need在否定句中当做情态动词用,后接动词原形 当行为动词用时要用 don't/doesn't need to do
逄珊震4328you needn't be told twice about one thing. -
杜泽阳13467003453 ______ need 后直接加了not,表明need用作情态动词(情态动词直接加not,构成否定形式).既然need是情态动词,情态动词后要接动词原形的,所以用be.be 是am, is ,are 的原形.
逄珊震4328you need to finish your homework first,need 词性.need后为何用to -
杜泽阳13467003453 ______ 因为need这里作实际动词.两个动词之间要加to
逄珊震4328'You needn't have said that,' my wife answered. -
杜泽阳13467003453 ______ needn't have done,不必做什么(但事实上却已经做了)'You needn't have said that,' my wife answered.说明已经那样说了,所以用needn't have.类似的shouldn't have none 不应该做什么(实际上已经做了) 例:You needn't have come so early.你不必这么早就来了.(已经来了) You shouldn't have been late for the meeting.你那次会议不应该迟到(实际上已经迟到了)
逄珊震4328I don't think he needs help 问一下need为什么加s don't后不是加原形吗? -
杜泽阳13467003453 ______ 这是宾语从句 所以不是看don't,后面think已经是动词原形了 need是跟着he的,第三人称单数后面加s
逄珊震4328是need do还是need to do?为什么didn't need to do 是不必要做也没做?
杜泽阳13467003453 ______ need有两种用法 1.作行为动词,意为“需要做....”接不定式是人需要...接ing是物需要... 2.情态动词,常用于否定句,needn't do 不必做... 人物通用,物要用被动 对号入座,那句话就是不必要去做....
