yes, you must.注意：neednt have done“表示本来不必做某事而实际上做了某事”。例如：you neednt have waited for me.“should have done”表示应该做到而实际上没有做到。you should have started earlier.“ought to have done”表示过去应做某事而实际未做。you ought to have helped him (but you didnt)书报的标题,小说等情节介绍常用一般现在时。表示感觉,愿望和状态的某些动词如have, be, hear, see, like等词一般不用进行时。有些动词形式上是主动结构,但表示被动的意思。常见的有可和 well, easily 等副词连用的不及物动词sell, wash, write, read, clean, cook等。例如：the cloth washes well.这布很禁洗。the new product sells well.这新产品很畅销。the pen writes well.这支笔很好写。在动词 arrange, command, demand, desire, insist, order, propose, request, require, suggest等后面的宾语从句中用“(should) 动词原形”(虚拟语气)例如：we suggested that we (should) have a meeting.we insisted that they (should) go with us.the doctor ordered that she (should) stay in bed for a few days.he demanded that we (should) start right away.作advice, idea, order, demand, plan, proposal, suggestion, request等名词的表语从句和同位语从句,其谓语动词要用虚拟语气的结构“(should)动词原形”。例如：we all agreed to his suggestion that we(should) go to beijing for sightseeing.my idea is that we (should) do exercises first.在feel, hear, notice, observe, see, watch, have, let, make等词后的补足语中,不定式不带to。但是这些句子如果变成被动结构时, 就必须带to。例如：i often hear him sing the song. he is often heard to sing the song.注意：不定式动词在介词but, except, besides后面时,如果这些介词之前有行为动词do的各种形式,那么,这些介词后的不定式不带to,否则要带to.如：she could do nothing but cry. what do you like to do besides swim?i have no choice but to go.作定语的不定式如果是不及物动词,或者不定式所修饰的名词或代词是不定式动作的地点、工具等,不定式后面须有相应的介词。例如：he is looking for a room to live in. there is nothing to worry about.please give me a knife to cut with.there / it is no use/ good/ not any use/ good/ useless doing sth.动词后可以用动名词作宾语,但不能用不定式:admit, appreciate, avoid, consider, delay, enjoy, escape, excuse, feel like, finish, forgive, give up, imagine, include, keep, mention, mind, miss, practise, put off, resist, risk, suggest, cant help, cant stand(无法忍受)等。i tried not to go there.(我设法不去那里。) i tried doing it again.(我试着又干了一次。)mean to do 有意. mean doing意味着.i mean to come early today.(我打算今天早些来。)missing the train means waiting for another hour.(误了这趟火车意味着再等一个小时。)allow, advise, forbid, permitwe dont allow smoking here. we dont allow students to smoke.动词need, require, want作“需要”解,其后跟动词作它的宾语时,若表示的含义是被动的,必须用动名词,或不定式的被动式。例如：the window needs(requires, wants)cleaning(to be cleaned).在短语devote to, look forward to, pay attention to, stick to, be used to, object to, thank you for, excuse me for 等后的动词也必须用动名词形式：i look forward to hearing from you soon.badly polluted, the water cannot be drunk.(原因)being written in haste, the composition is full of mistakes.(原因,强调写的过程,故应用现在分词一般被动式)having been deserted by his guide, he couldnt find his way through the jungle.(为了强调已完成的动作)asked to stay, i couldnt very well refuse.这里 asked 可能意味着 having been asked, 也可能意味着when/since i was asked, 但用了 having been asked 就不会有歧义。下面句中过去分词表示的时间与谓语动词所表示的时间相同，所以不能代之以强调先于谓语动词的现在分词完成被动式。例如：covered with confusion, i left the room.我很窘地离开了房间。united, we stand; divided, we fall. 团结则存，分裂则亡。he used to live in london, use(d)nt he /didnt he?there used to be a cinema here before the war, use(d)nt there /didnt there?such things ought not to be allowed, ought they?he ought to be punished, oughtnt he?但在正式文体中,用ought we not形式。例如:we ought to go, ought we not?或we ought to go ,should we not?含有情态动词must的句子表示推则,作“想必”解时,疑问部分不可用mustnt。若前句强调对现在情况的推测,疑问部分用arent(isnt)十主语,例如：you must be tired, arent you?若陈述部分的must表示“有必要”时,附加疑问句部分则用neednt。例如：you must go home right now, neednt you?当mustnt 表示禁止时,附加疑问部分一般用must。如：you mustnt walk on grass, must you?前句谓语动词是must have过去分词时,若前句强调对过去情况的推测(一般有过去时间状语),疑问部分的谓语动词用didnt主语;若前句强调动作的完成,疑问部分的谓语动词用havent(hasnt)主语, 例如：he must have met her yesterday, didnt he?you must have seen the film, havent you?陈述句谓语部分出现否定词缀时(前缀或后缀),疑问部分仍用否定结构。例如:he is unfit for his office, isnt he?如果陈述部分包含有no, never
