动词suppose意思是“假定,认为,想象,需要……条件”suppose后直接跟宾语。比如:
An invention supposes an inventor.
要有发明,必须先有发明者。
再比如:
Let us suppose another war.
让我们假定再来一场战争吧。
suppose可以跟that引导的从句,表示“认为,猜想”,从句用将来时或一般现在时(表示将来要发生的动作)。比如:
I suppose that you will be there.
我猜想你会到那里去的。
再比如:
I suppose it rains tomorrow.
我猜想明天会下雨。
suppose也可以用在祈使句中。比如:
Suppose your mother saw you now.
假如现在你妈妈看见你呢。
suppose的另外一种用法是suppose后面跟that引导的从句,从句中要用将来时态,表示“想,认为”。比如:
I suppose that he will be here at nine.
我想他9:00会来。
suppose+that+真实条件句,表示“假如,如果”,suppose是从属连词,不是动词。可表示提出建议或请求,也可表示某种“假定”。比如:
Suppose I were dismissed,what should I do?
假如我被解雇了,该怎么办呢?
Suppose it rains,what shall we do?
假如下雨,我们怎么办?
另外一个需要掌握的句型是suppose sb or sth+动词不定式。比如:
I suppose him to be about fifty.
我猜想他50岁左右。
再比如:
They supposed the box to contain gold.
他们猜想那个匣子装着金子。
另外一个常考为结构为:be supposed to do sth.这个结构是个被动形式,其中的to是动词不定式符号,后面要跟动词原形。句子的主语可以是人,也可以是物。当人做主语时,它的意思是“应该;被期望;有义务做”表示劝告、建议、义务、责任等。当物做主语时,表示“本应;本该”,多指某事本应该发生而没有发生。比如:
We are supposed to start work tomorrow every morning.
我们理应明早开始工作。
The plane was supposed to take off twenty minutes ago.
飞机应该在二十分钟之前起飞。
Everyone is supposed to bring a bottle to the party.
每个人都应该带一瓶酒参加宴会。
请看一个考题:
They_____to meet at the school gate at six o'clock in the morning.
A.will suppose B.are supposed C.supposed D.should be supposed
题句的意思是:他们要在早晨六点钟在校门口集合。这里选B,用be supposed to结构,后面跟原形动词meet。
另外suppose延伸出来的supposing这个词,是从属连词,意思是“倘若,假使”,后面可以跟句子。比如:
Supposing(that)you are wrong,what will you do then?
假设你错了,那你会怎么办?
Objections to this plan--supposing there should be any--must be made directly.
对这个计划的反对意见——假使有的话——,请马上提出。
原句将supposing there should be any插在句子中间了。
