1. They were expected to be here one hour ago.

再问： be expected to do和be supposed to do意思上有什么区别吗
再答： 一般考试来说的话，是没什么区别，都是“应该做某事”的意思 如果一定要细细区分的话，be supposed to do是被期望或要求,应该.相对于be expected to do 主观性强一些.初中阶段学它相当于should的这个用法 expect在朗文的第一词条即为：预料、期待。 例：They are expected to make an announcement later on today.(预料他们今天晚些时候会宣布一项通告) 再次例句中，be expected to do意为预料，表示一种可能性 再如：She is expected to be a good doctor.（他有希望成为一名好医生)
