be supposed to 的用法
用法一: be supposed to... 其中to是动词不定式符号,不是介词,其后要跟动词原形。当be supposed
to... 的主语是“人” 时,意为“应该……
”;“被期望……”,它可以用来表示劝告、建议、义务、责任等,相当于情态动词should。如:
Everyone is supposed to wear a seat-belt in the car.
每个人在汽车里都应该系安全带。
Teachers are supposed to treat all the students alike.
老师应该对所有的学生一视同仁。
用法:当be supposed to... 的主语是“物”时,它表示“本应;本该”,用于表示“某事本应该发生而没有发生”。如:
The new laws are supposed to prevent crime. 这些新法令本应该起到防止犯罪的作用。
The train was supposed to arrive half an hour ago. 火车本应在半小时之前到达。
用法三: be supposed to后面接“have + 过去分词”时,表示“本应该做某事而没做”。如:
You are supposed to have handed in your homework by now.
现在你应该已经把作业交上来了。
He is supposed to have arrived an hour ago. 他应该一小时前就到了。
用法四: be supposed to... 的否定结构为be not supposed
to...,它常用于口语中,意为“不被许可;不应当”。如:
She was not supposed to be angry about that. 她本不该为那件事而生气的。
You are not supposed to smoke on the bus. 你不应该在公共汽车上吸烟
