suppose的用法总结
suppose作为动词，其意思是“猜想，设想，认为，假设”，其常见用法为:
1. be supposed to do sth.意思是“被期望做某事；应该做某事”，to是不定式符号，不是介词，后接动词原形。be supposed to常用来表示劝告、建议、 告知义务或责任等，相当于should。如:
He is supposed to arrive on time.他应该准时到达。
You are supposed to ask the teacher if you want to leave the classroom.如果你要离开教室，你应该问问老师。
You are supposed to shake hands.你应该去握手。
2. 在口语中，常用否定结构“be not supposed to do sth.”，意思是“不允许做某事；不应该做某事”，相当于shouldn't。如:
You are not supposed to smoke on the bus.(＝You shouldn't smoke on the bus.)你不应该在公共汽车上吸烟。
We are not supposed to play football in the street.我们不应该在大街上踢足球。
3. be supposed to have done sth.意为“本应该做某事而没有做”。如:
You are supposed to have handed in your homework.你本应该已经交了作业。
4. supposed＋that从句，当变为否定句时，否定词应该前移。类似的词还有think，believe等。如:
I don't suppose he will tell you about it.我认为 他不会告诉你这件事。
I don't think he will come.我想他不会来了。
5. suppose还有“猜想”的意思，suppose sb.to do sth.的意思是“猜想某人去做某事”。如:
I supposed him to stay at home.我猜他待在家。
6. 如果表达“过去某时应该(不应该)做”时，用 was(wasn't)/were (weren't) supposed to，相当于should(shouldn't) have＋动词的过去分词。如:
I was supposed to arrive at 7:00，but I arrived at 8:00.我应该7点钟到，却在8点钟到。
