Unit 10 You're supposed to shake hands.
核心语法：be supposed to 的用法
一、 核心含义
be supposed to 是一个非常重要的短语，它相当于一个情态动词，没有人称和数的变化（be 随主语变化为 am, is, are 等），后接动词原形。它的核心含义主要有三个：
应该，应当（表示责任、义务或预期）
被期望，被认为（表示普遍的看法或规定）
本应该（用于过去时，表示该做而未做的事）
二、 用法一：表示“应该，应当”
这种用法用来表示职责、义务、规则或按计划、安排应该发生的事。常可与 should 互换，但语气比 should 更强、更正式。
结构： am/is/are supposed to + do
例句：
You are supposed to finish your homework before you watch TV. （你看电视应该先完成作业。）- 表示规定/义务
Students are supposed to wear uniforms at school. （学生在学校应该穿校服。）- 表示规则
The train is supposed to arrive at 8:00. （火车应该8点钟到。）- 表示预期/安排
三、 用法二：表示“被期望，被认为”
这种用法表示一种普遍的信念、看法或期望，意思是“人们认为...”、“大家都觉得...”。
结构： am/is/are supposed to + do / be
例句：
Coffee is supposed to help you stay awake. （咖啡被认为能帮你保持清醒。）
He is supposed to be the best student in his class. （大家都认为他是班里最好的学生。）
This restaurant is supposed to be very good. Let's try it. （这家餐馆据说很好。我们去尝尝吧。）
四、 用法三：表示“本应该”（过去未实现）
这是中考的重点和难点。用 was/were supposed to 表示过去本来应该做某事，但实际并没有做。含有一种批评、失望或意外的语气。
结构： was/were supposed to + have done (更强调) 或 was/were supposed to + do
例句：
You were supposed to clean your room yesterday. （你本来应该昨天打扫房间的。 - 暗示你没打扫）
The meeting was supposed to start at nine, but it was delayed. （会议本来应该九点开始，但是推迟了。）
I was supposed to have finished the report by Friday. （我本应该在周五前完成这份报告的。 - 但我没完成）
五、 否定形式与疑问形式
1. 否定形式： be not supposed to，表示“不应该、被禁止做某事”，相当于 should not 或 must not，但语气更客观。
You are not supposed to smoke here. （这里不允许吸烟。）
We are not supposed to tell anyone the secret. （我们不应该告诉任何人这个秘密。）
2. 疑问形式： 将 be 动词提前。
Are we supposed to hand in our essays today （我们今天应该交作文吗？）
What am I supposed to do next （我下一步应该做什么？）
六、 总结与易错点
结构永恒： 永远记住结构是 be + supposed + to do。to 是不定式符号，后面必须接动词原形。
（√）You are supposed to come. （你应该来。）
（×）~~You are supposed come.~~
（×）~~You are supposed to coming.~~
“be” 要变形： be 动词要根据主语变为 am, is, are, was, were。
I am supposed to...
He is supposed to...
They were supposed to...
核心区别：
现在时 (am/is/are)： 表示现在或未来的“应该”或“被认为”。
过去时 (was/were)： 常表示“本应该（但没做）”。
与 should 的区别：
should 更侧重表达主观看法或建议。
be supposed to 更侧重表达客观规则、外界期望或普遍看法。
