suppose意为假设、设想,以下分别为牛津词典和柯林斯词典给出的解释:
Oxford: to pretend that sth is true; to imagine what would happen if sth were true.
Collins: You can use suppose or supposing before mentioning a possible situation or action. You usually then go on to consider the effects that this situation or action might have.
例句:1. Suppose flights are fully booked on that day—which other day could we go?
2.Suppose someone gave you an egg and asked you to describe exactly what was inside...
我的理解是第一句是有可能发生的事情,所以时态是现在时,第二句是虚拟语气,所以用过去时?用法是否和if一样,既可用作虚拟又可以假设很有可能发生的事情?
1.suppose常可与supposing互换使用,既可用于陈述语气,也可用于虚拟语气。《葛传槼英语惯用法词典》有以下例句:
下面每组里的两句意思相同:
Suppose he is absent, what shall we do?
Supposing he is absent, what shall we do?
Suppose he were absent, what should we do?
Supposing he were absent, what should we do?
2.suppose(祈使语气)和supposing(现在分词)均可视为连词引导条件状语从句,意为“假若;如果”,主句通常为疑问句。例如:
Suppose / Supposing we miss the train, what shall we do? 假如我们误了火车,我们怎么办?
▲ suppose必须置于句首,因为它是动词,构成祈使句表示“条件”,而supposing却无此限制,因为它可以视为连词。例如:
We'd love to come and see you on Saturday, supposing I don't have to work that day. 我想星期六来看你,假若那天我不上班的话。
