探究一：be suppsed t 的结构和用法
What did yu find ut?
be suppsed t, 意为“(按规定、习惯、安排等）应该做某事”，可用来表示劝告、建议、义务、责任等，相当于shuld的用法。 否定形式为“be nt suppsed t d sth.” 表示不该或禁止做的事情。 t为不定式符号，后接动词原形。时态、人称和句式的变化在be动词上体现。If yu want t eat ice-cream, yu are suppsed t ask yur mum. 如果你想吃冰淇淋，应该先问问你妈妈。
1. 当be suppsed t d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。t为动词不定式符号，后接动词原形。
车上的每个人都应该系安全带。Everyne is suppsed t wear a seat-belt in the car.
Yu’re suppsed t return my mney tday.
当be suppsed t的主语是人时，后面还可以接“have + V-ed”，意为“本应，应该”，表示本应该做某事而没做。相当于shuld have dne。
你本应该现在已经到了北京了。Yu are suppsed t have arrived in Beijing nw.
Yu are suppsed t have dne yur hmewrk。你本应该能完成作业的.
2.当be suppsed t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”。
火车本应在半小时之前到达。The train was suppsed t arrive half an hur ag.
The sprts meeting was suppsed t take place n Tuesday, but we’ve had t put it ff because f the heavy rain.
3. be suppsed t d sth.的否定形式为：在be动词后加nt。 be nt suppsed t d sth. ，意为“不应该做某事”，表示命令或禁止。 Yu are nt suppsed t d that. 你不应当做那件事。
Yu are nt suppsed t talk ludly in the hspital.
4. be suppsed t d sth.的一般疑问句形式为：把be提至主语前。
Am I suppsed t get up at 7 ’clck?
5. 如果表达“过去某时本应该(不应该)做，而实际上没有做 ”时，用was (wasn’t) / were (weren’t) suppsed t d, 相当于shuld (shuldn’t) have+动词过去分词。
They were suppsed t arrive at nine, but they were late.
He was suppsed t arrive an hur ag.
6. be suppsed t还可表示“被认为……；被相信……”。 They are suppsed t be very clever. 他们被认为很聪明。
The dlphins are suppsed t be very clever.
7. be suppsed t have dne表示“本应该做某事（实际上没做）”，相当于shuld have dne。
8. be suppsed t d sth. ＆ shuld的区别
be suppsed t的语意相当于shuld。如：Yu’re suppsed t study harder. = Yu shuld study harder. 但是，be suppsed t d sth为系表结构，强调客观上有责任/义务作某事。 Yu are suppsed t clean the blackbard, fr yu are n duty tday. shuld 强调主观上应该做某事。Yu shuld study hard, fr yu are a student.
1.如果你想离开教室的话，你应该问问老师。 Yu_____ _______ ______ ask the teacher if yu want t leave the classrm.2. 这次会议本应在星期二举行，但我们不得不把它推迟了。 This meeting ____ ________ _____ take place n Tuesday, but we have t put it ff.我本应该今天上午寄信的，但我忘了。I ____________________ the letter this mrning, but I frgt it.
探究二：be expected t 的结构和用法
be expected t d sth. 意为“应该做某事”，“被期望做某事”或，“被要求做某事”其表达的主观性比be suppsed t d sth. 更强。Yu’re expected t d yur duty.你应该恪尽职责。
She was expected t arrive befre dinner.希望她晚餐前到达。
I’m expected t d the dishes every day. 我被要求每天洗餐具。
探究三：It is + adj. + t d sth. 的结构和用法
It is + adj. + t d sth. 意为“做某事是……的”，其中It为形式主语，真正的主语是后面的动词不定式（短语）。I think it is imprtant t sleep fr eight hurs a night.
该句型中it为形式主语，真正的主语为动词不定式t d sth.被移到了句子后面，使句子变得平稳。如果把真正的主语放到前面，那么主语过长，整个句子就显得头重脚轻。
It be imprtant t d sth. 做某事很重要。It is imprtant t learn English well. 学好英语很重要。
辨析：It is＋adj.＋fr sb. t d sth. It is＋adj.＋f sb. t d sth.
动词不定式（短语）的逻辑主语
It is +adj. +fr sb. t d sth.
该句型使用的adj.描述的是事物的特征。常用描述事物性质的形容词，这类形容词有difficult, easy, hard, imprtant, (im)pssible, dangerus等。
It’s difficult fr me t learn English well.
It's nt easy fr the man t supprt such a big family.养活这么一大家子人对这个男人来说不容易。
It is +adj. +f sb. t d sth.
