一、Suppose做及物動(dòng)詞,意為“想,認(rèn)為,猜想,料想”,用法如下：
　　1.suppose后接that引導(dǎo)的賓語從句,that可以省略,如：
　　I suppose we’ll go there next week.
　　我猜想我們下周將去那兒.
　　2.suppose +名詞/代詞+[ (to be）+表語]賓語補(bǔ)足語,如：
　　What makes you suppose him to be connected with them?
　　你怎么會認(rèn)為他與他們有聯(lián)系呢?
　　3.suppose+名詞/代詞+不定式,如：
　　I supposed her to have already left for home.
　　我認(rèn)為她已經(jīng)動(dòng)身回家了.
　　4.suppose+名詞/代詞+名詞（賓語補(bǔ)足語）,如：
　　I never supposed him a hero.
　　我從來沒有認(rèn)為他是一個(gè)英雄.
　　5.suppose+名詞/代詞+形容詞 （賓語補(bǔ)足語）,如：
　　We all suppose him clever.
　　我們所有的人都認(rèn)為他很聰明.
　　6.suppose+名詞 /代詞+介詞短語,如：
　　I supposed him in the office.
　　我想他在辦公室.
　　7.suppose做插入語,如：
　　You don’t mind my smoking,I suppose.
　　我想你不會介意我抽煙.
　　使用suppose時(shí)應(yīng)注意：
　　1.I suppose可以用來有禮貌地要求一個(gè)肯定的答復(fù),如：
　　I suppose (that) you are very busy just at the moment?
　　我想你這會兒正忙吧?
　　2.suppose,guess與imagine的區(qū)別：
　　suppose多用于口語,是試探性的,但有一定的根據(jù)；guess隨意性很強(qiáng),缺乏依據(jù)；imagine指“設(shè)想”、“想象”與眾所周知的事實(shí)相反的東西,強(qiáng)調(diào)虛構(gòu)和幻想.如：
　　I suppose they will leave here tomorrow.
　　我猜他們明天要離開這兒了.
　　Can you guess what I mean?
　　你能猜出我的意思嗎?
　　I imagine that you are tired.
　　我猜想你已經(jīng)累了.
　　3.在英語中,含suppose的句子是用否定主句謂語的方式來否定后面賓語從句的內(nèi)容的（即把賓語從句的否定詞 not轉(zhuǎn)移到否定主句謂語動(dòng)詞上來）,這種語言現(xiàn)象叫做轉(zhuǎn)移否定,在這種用法中,suppose意為“想,認(rèn)為,猜想,料想”；賓語從句是由that引導(dǎo)的賓語從句,也是由否定詞 not構(gòu)成的否定,主句主語多為第一人稱.如:
　　I don’t suppose I’ll trouble you.
　　我想我不會再麻煩你.
　　I don’t suppose（that）I shall be back until eight o’clock.
　　我看我在8點(diǎn)前回不來.
　　I didn’t suppose (that) it was true.
　　我猜想那不是真的.
　　4.suppose后也可接so代替整個(gè)賓語從句,但如果賓語從句為否定句時(shí),只能轉(zhuǎn)移否定,不能用not否定so,當(dāng)然也可用否定詞 not代替整個(gè)賓語從句.如：
　　-Will he come?
　　-他會來嗎?
　　-Yes,I suppose so./ No,I suppose not./ No,I don’t suppose so.
　　-我想他會來./不,我想他不會來./不,我認(rèn)為他不會來.
　　正：I don’t suppose so./I suppose not.
　　我認(rèn)為不是這樣.
　　誤：I suppose not so.
　　二、suppose作“假定,設(shè)想”講,有時(shí)表示自己有一定根據(jù)的猜想,有時(shí)僅表述自己的意見.如：
　　Let’s suppose that we had not helped him,what would happen?
　　假定我們當(dāng)時(shí)沒有幫助他,他會怎樣呢?
　　Suppose it rained,we would still go.
　　假如下雨的話,我們還是要去.
　　三、構(gòu)成祈使句,表達(dá)一項(xiàng)提議或建議,作“讓、怎么 ,如何”講,從句中用過去式,語氣更委婉.如：
　　Suppose you meet me at the office at half past seven.
　　你7:30與我在辦公室見面如何.
　　Suppose (=Let’s go) for a swim.
　　我提議我們?nèi)ビ斡?
　　Suppose we went for a walk!
　　我們?nèi)ド翰桨?
　　四、用于被動(dòng)語態(tài),作“應(yīng)該、被認(rèn)為,理應(yīng),應(yīng)該”講.如：
　　You are supposed to be here at nine.
　　你應(yīng)該在9點(diǎn)鐘到達(dá)這里.
　　Everyone is supposed to know the rules.
　　大家理應(yīng)知道這些規(guī)則.
　　At the moment he is supposed to be in Paris.
　　人們認(rèn)為他目前在巴黎.
　　五、口語中,用于被動(dòng)語態(tài)的否定句,作“許可”講.如：
　　You are not supposed to smoke on the bus.
　　你不能在公共汽車上抽煙.
　　We are not supposed to play football on Sundays.
　　我們在星期天不許踢足球.
　　He’s not supposed to do that.
　　你不應(yīng)該做那件事.
　　六、suppose的過去分詞或過去式也可做形容詞,意為“被信以為真的,假定的,推測的”.如：
　　The supposed beggar is really a police officer in disguise.
　　大家都認(rèn)為是乞丐的那個(gè)人原來是一個(gè)喬裝的警察.
　　七、suppose的現(xiàn)在分詞也可做連詞,相當(dāng)于if.如：
　　Supposing it rains,what will you do?
　　如果下雨你怎么辦呢?
