be suppsed t 意为“应该……”，相当于 shuld；be expected t意为“应该……；被期望……”。两者都用来表示根据规定、传统或习惯应该做某事或期待某事发生，两者中的t为不定式符号，后接动词原形。
be suppsed t和be expected t的用法
一、be suppsed t 的用法
1. 当主语是人时be suppsed t的主语是人时，意为“应该……”，用来表示劝告、建议、责任等。否定形式为be nt suppsed t d sth. ，意为“不应该做某事”，表示命令或禁止。Students are suppsed t learn bth knwledge and basic life skills.学生们应该学习知识和基本的生活技能。Children are nt suppsed t play n the street because it’s really dangerus孩子们不应该在街上玩耍，因为太危险了。
