1.suppose的基本意思是指在证据不全、情况未确定时所作的猜想。可指缺乏确切的事实但可根据一些现象来推测; 也可指提出合乎逻辑推理的假设来论证某事; 还可指委婉地提出建议。
2.suppose用作及物动词,可接名词、代词或that/wh-从句(可用于虚拟式)作宾语。还可接以“(to be+) n./adj. / prep. -phrase”或动词不定式、现在分词充当补足语的复合宾语。suppose搭用to be构成的复合宾语,如用于被动结构, to be有时可以省去。
3.suppose作“作为建议来考虑”解时,常用于祈使句,用以提出建议,可译为“…如何〔怎么样〕?”。与“what if”用法相似,动词一般用现在时或过去时。用过去时时,所提建议听起来不十分肯定。
Suppose you have a thousand dollars, what will you do with it.
