一、關于否定轉(zhuǎn)移

表示“想”、“認為”、“料想”等，后接否定的賓語從句時通常將否定轉(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. 我看他不會及時來的。

注意以下簡略答語的使用：

A：Will he win? 他會贏嗎?

B:I suppose so. 我想他會贏吧。

B:I don’t suppose so. [I suppose not. ] 我想他不會贏。

二、關于詞序

2. 注意以下正誤句型的詞序:

你認為他會去了哪里呢?

正：Where do you suppose he has gone?

誤：Do you suppose where he has gone?

你認為是誰偷了這錢呢?

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“應該”、“理應”，其后接動詞原形(有時為進行式或完成式)。如：

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

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

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

注：用于否定句，有時表示委婉地禁止，意為“不應當”、“不可”、“不許”。如：

You’re not supposed to smoke in here. 此地不準吸煙。

另外請比較：

他們本來應該在一小時以前趕到這兒的。

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(相當于連詞 if)，意為“假設”，也可用 -ing的形式，若語氣不肯定，有時還可用虛擬語氣。試比較:

假若他不來，那我們怎么辦? 

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”，后接從句時可用現(xiàn)在時態(tài)或過去時態(tài)，相比之下用過去時語氣更委婉。如：

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

Suppose we start [started] tomorrow. 我們明天動身吧。
