一、關(guān)于否定轉(zhuǎn)移

表示“想”、“認(rèn)為”、“料想”等，后接否定的賓語從句時(shí)通常將否定轉(zhuǎn)移到主句上。如：

I don’t suppose he is really ill. 我看他不是真病了。

I don’t suppose that he will come in time. 我看他不會(huì)及時(shí)來的。

注意以下簡(jiǎn)略答語的使用：

A：Will he win? 他會(huì)贏嗎?

B:I suppose so. 我想他會(huì)贏吧。

B:I don’t suppose so. [I suppose not. ] 我想他不會(huì)贏。

二、關(guān)于詞序

2. 注意以下正誤句型的詞序:

你認(rèn)為他會(huì)去了哪里呢?

正：Where do you suppose he has gone?

誤：Do you suppose where he has gone?

你認(rèn)為是誰偷了這錢呢?

正：Who do you suppose has stolen the money?

誤：Do you suppose who has stolen the money?

三、用于be supposed to

用于 be supposed to, 意為“應(yīng)該”、“理應(yīng)”，其后接動(dòng)詞原形(有時(shí)為進(jìn)行式或完成式)。如：

You are supposed to be there before dark. 你應(yīng)該在天黑前趕到那兒。

He’s supposed to be doing his homework at home now. 他現(xiàn)在應(yīng)該在家里做作業(yè)。

He is supposed to have written us a letter. 他本來應(yīng)該給我們寫封信的。

注：用于否定句，有時(shí)表示委婉地禁止，意為“不應(yīng)當(dāng)”、“不可”、“不許”。如：

You’re not supposed to smoke in here. 此地不準(zhǔn)吸煙。

另外請(qǐng)比較：

他們本來應(yīng)該在一小時(shí)以前趕到這兒的。

正：They were supposed to be here an hour ago.

正：They are supposed to have been here an hour ago.

四、用作連詞

用來表示條件(相當(dāng)于連詞 if)，意為“假設(shè)”，也可用 -ing的形式，若語氣不肯定，有時(shí)還可用虛擬語氣。試比較:

假若他不來，那我們?cè)趺崔k? 

正：Suppose [Supposing] he is absent, what shall we do?

正：Suppose [Supposing] he was absent, what should we do?

五、表示建議

用來表示建議，意為“……吧”、“……怎么樣”，后接從句時(shí)可用現(xiàn)在時(shí)態(tài)或過去時(shí)態(tài)，相比之下用過去時(shí)語氣更委婉。如：

Suppose we have [had] a rest. 我們休息一會(huì)兒吧。

Suppose we start [started] tomorrow. 我們明天動(dòng)身吧。
