人教版初中英语九年级下册 Unit10语法、阅读、写作专题 语法专题 一、 be supposed to do sth.与 be expected to do sth.结构 1.be supposed to do sth."应该做某事"。它用来表示根据规定或传统习惯，人们不得不做的事或期待发生的事。其时态、人称和句式的变化体现在be动词上。to为不定式符号，后接动词原形。 (1)be supposed to do sth.的句式结构 ①肯定句：主语+be supposed to do sth. 例：You were supposed to arrive at 6:00,but you arrived at 7:00. 你应该在6点到，可你7点才到。 ②否定句：主语+be+not supposed to do sth. 例：You're not supposed to come to school late.你不应该上学迟到。 一般疑问句：Be+主语+ supposed to do sth. 例：Are you supposed to finish homework first?你应该首先完成家庭作业吗？ ④特殊疑问句：疑问词+be+主语supposed to do sth.? 例：What are you supposed to do in class?在课堂上你应该做什么？ 小贴士 当疑问词为who时，句式应为：Who+be supposed to do sth.? 例：Who is supposed to give the report today?今天该谁做报告？ (2)be supposed to do sth.的用法 ①当 be supposed to do sth.的主语是“人”时，意为“应该做某事；被期望做某事”，可用来表示劝告、建议、义务、责任等，相当于should/ought to do sth.。例：You're supposed to/should/ought to put up your hand,if you have some questions in class.如果你在课堂上有什么问题，你应该举手。 ②当 be supposed to do sth.的主语是“物”时，意为“本该做某事”，用于表示某事本应该发生而实际并没有发生。 例：The train was supposed to come an hour ago.火车本应在一个小时前到。 2.be expected to do sth.“被期待做某事；应该做某事”。它比 be supposed to do sth. 的主观性更强。 例：Parents can't be expected to watch their children 24 hours a day. 父母不可能一天24小时照看孩子们。 二、It +be + adj.+ to do sth.句型 在“It + be+ adj.+ to do sth.”结构中，it是形式主语，而真正的主语是动词不定式（短语）。 例：It is important to study English well.学好英语是非常重要的。 这种结构还包含两种常考的复合结构： (1)在“It + be+ adj.+ of sb.to do sth."结构中，形容词是描述人的性格、品质的词。 例：It is very kind of you to help me last night.你昨晚帮我真是太好了。 (2)在“It+ be+ adj.+ for sb.to do sth."结构中，形容词是描述事物特征的词。例：It is hard for me to finish this task.完成这项任务对我来说很难。 语法专练 单项选择 1.
