be supposed to 的用法

suppose如何用

suppose的基本意思是“猜想;以为;假定”,但在具体的语言环境中意义不止于此,其用法如下:

1. suppose + that 从句,表示“猜测;假定”。如:

I suppose that you are right. 我想你是对的。

You can suppose that A equals B. 你可以假定A等于B。

2. suppose +名词 / 代词 + ,表示“认为„„是„„”。如:

Many people suppose him to be over 50. 许多人认为他已经50多岁了。

3. suppose用于祈使句中,表示“让„„”。如:

Suppose we go for a swim. (= Let's go for a

swim.) 让我们去游泳吧。

be supposed to 的用法

用法一: be 其中to是动词不定式符号,不是介词,其后要跟动词原形。当be 的主语是“人” 时,意为“应该„„ ”;“被期望„„”,它可以用

来表示劝告、建议、义务、责任等,相当于情态动词should。如:

Everyone is supposed to wear a seat-belt in the

car.

每个人在汽车里都应该系安全带。

Teachers are supposed to treat all the

students alike.

老师应该对所有的学生一视同仁。

用法二:当be 的主语是“物”时,它表示“本应;本该”,用于表示“某事本应该发生而没有发生”。如:

The new laws are supposed to prevent crime. 这些新法令本应该起到防止犯罪的作用。

The train was supposed to arrive half an hour

ago. 火车本应在半小时之前到达。

用法三: be supposed to后面接“have + 过去分词”时,表示“本应该做某事而没做”。如:

You are supposed to have handed in your

homework by now.

现在你应该已经把作业交上来了。

He is supposed to have arrived an hour ago. 他应该一小时前就到了。

用法四: be 的否定结构为be not

supposed

to...,它常用于口语中,意为“不被许可;不应当”。如:

She was not supposed to be angry about that.

她本不该为那件事而生气的。

You are not supposed to smoke on the bus. 你不应该在公共汽车上吸烟。

suppose的其他用法:

1.suppose + that 引导的宾语从句“假设,猜想,以为”。例如:

Let's suppose that you had a million dollars, how would

you spend it?

假如你有一百万美元,你怎么花呢?

I suppose that she'll be there today.

我想她今天能到那里。

I had supposed he had died years ago.

我原以为他几年前就去世了。

2. 当suppose + that 引导的宾从变为否定句时,否定应前移,有此种用法的词有think, believe, guess(猜想)等。例如:

I suppose that she will come to your party.

→ I don't suppose that she will come to your party.

我猜她不会来参加你的晚会。

I suppose that he will agree with you.

→ I suppose that he will agree with you.

3. 在表示同意或不同意别人的观点时,常用“I suppose so/ I

don't suppose so”。

--- Will he be back this weekend?

他周末会回来吗?

--- Yes, I suppose so.

我想他会回来。
