一、be supposed to do句型的应用
be supposed to do在本单元是“应该,被期望,理应”之意。用来表示根据规定,人们不得不做的事,或期待发生的事。时态、人称和句式的变化在be上体现,to为不定式符号,后接动词原形。
1. be supposed to do的肯定句式:
Everyone is supposed to wear a seat belt in the car.
每个人在小汽车里都应该系好安全带。
You’re supposed to start work at 8:30 every morning.
你应该每天早晨8:30开始工作。
They are supposed to shake hands.
他们应该握手。
2. be supposed to do的疑问句式需将be动词的相应形式提到主语前。例如:
Is he supposed to get there at five? 他应该在5点钟到吗?
Was Lucy supposed to speak Chinese like that? 露西应该像那样说汉语吗?
What are you supposed to do?
你们应该做什么?
When were you supposed to arrive?
你们应该什么时候到?
3. be supposed to do的否定式,即在be动词后加否定副词not,此时相当于be not allowed to do,意为“不被许可,不应当”。例如:
You are not supposed to smoke here.
你不应该在这里抽烟。
We are not supposed to play football in the street. 我们不应该在大街上踢足球。
It is a secret still. I am not supposed to say. 这还是个秘密,我不能说出来。
4. be supposed to be有“某人/某事被认为如何”的意思。其主动形式为“suppose sb. to be+形容词/名词”。例如:
All the classmates suppose him to be stupid(=He is supposed to be stupid by all the classmates). But in fact, he is a good student. 所有同学都认为他愚蠢,事实上他是一个好学生。
People in old times supposed the earth to be flat(=The earth was supposed to be flat by people in old times). But now we know it is round. 古时候人们认为地球是平的,但我们现在知道它是圆的。
Jenny is supposed to be the best student in our class. 珍妮被认为是我们班里最好的学生。
Professor Wang is supposed to be the main speaker at the meeting.
王教授被认为是大会的主要发言人。
We suppose her to be an actress.
=She is supposed to be an actress.
我们认为她是个女演员。
二、suppose作及物动词,意为“想,认为,猜想,料想”,它的用法如下:
1. suppose后接that引导的宾语从句,that可以省略。例如:
I suppose we’ll go there the next week.
我猜想我们下周将去那儿。
2. suppose+名词/代词。例如:
What makes you suppose him to be connected with them?
你怎么会认为他与他们有联系呢?
3. suppose+名词/代词+不定式。例如:
I supposed her to have already left for home. 我认为她已经动身回家了。
4. suppose+名词/代词+名词(宾语补足语)。
例如:
I never supposed him a hero.
我从来没有认为他是一个英雄。
5. suppose+名词/代词+形容词(宾语补足语)。例如:
We all suppose him clever.
我们所有的人都认为他很聪明。
6. suppose+名词/代词+介词短语。例如:
I supposed him in the office.
我想他在办公室。
7. suppose作插入语。例如:
You don’t mind my smoking, I suppose.
我想你不会介意我抽烟。
三、构成祈使句,或用作一项提议或建议,作“让,怎么,如何”讲,从句中用过去式语气更委婉。例如:
Suppose you met me at the office at half past seven. 你七点半与我在办公室见面如何。
Suppose(=Let’s go) for a swim. 我提议我们去游泳。
Suppose we went for a walk!
我们去散会儿步吧!
四、suppose作动词时还有“假定,假使”之意,后接从句。suppose此时可当作if来使用,往往表示想象中的条件,这样使用,这个动词相当于supposing。作“如果”讲,则只能用supposing,不用suppose。例如:
Suppose it rains, what shall we do?
假如下雨我们怎么办?
Let’s suppose(that) he is telling a lie.
暂且假定他在说谎吧。
Supposing youmiss him, he is not likely to miss you.
即使你碰不到他,他也可能碰到你。(be likely to do可能做……)
五、使用这种意义的suppose时应注意:1. I suppose可以用来有礼貌地要求一个肯定的答复。例如:
I suppose(that) you are very busy just at the moment? 我想你这会儿正忙吧?
2. suppose, guess与imagine的区别:
suppose多用于口语,是试探性的,但有一定的根据;guess随意性很强,缺乏依据;imagine指“设想”、“想象”与众所周知的事实相反的东西,强调知觉虚构和幻想的作用。例如:
I suppose they will leave here tomorrow.
我猜他们明天要离开这儿了。
Can you guess what I mean?
你能猜出我的意思吗?
I imagine that you are tired.
我猜想你已经累了。
3. 在英语中,含suppose的句子要用否定主句谓语的方式来否定后面宾语从句的内容(即把宾语从句的否定词not转移到否定主句谓语动词上),这种语言现象叫否定转移,在这种用法中,suppose意为“想,认为,猜想,料想”;宾语从句是由that引导的,也是由否定词not构成的否定,主句主语多为第一人称。例如:
I don’t suppose I’ll trouble you.
我想我不会再麻烦你。
I don’t suppose(that) I shall be back until eight o’clock. 我看我在八点以前回不来。
I didn’t suppose(that) it was true.
我猜想那不是真的。
4. suppose后也可接so代替整个宾语从句,但如果宾语从句为否定句时,只能转移否定,不能用not否定so, 当然也可用否定词not代替整个宾语从句。例如:
——Will he come? 他会来吗?
——Yes, I suppose so./No, I suppose not./No, I don’t suppose so. 我想他会。/不,我想他不会。/不,我认为他不会来。
正:I don’t suppose so./I suppose not.
误:I suppose not so.
