人教版英语八年级下册Unit 1-5 单元语法知识梳理
Unit 1 单元语法知识梳理一、情态动词should的用法情态动词should有自己的意义，但不能单独作谓语，只能和其他动词一起构成谓语，表示说话人的态度或看法，后接动词原形。
常见用法有以下几点：1.表示劝告、建议等，意为“应该”，常指根据常理认为对的事或应该去做的事。
当劝某人做或不做某事时，常用“should do sth.”或“shouldn't do sth.”。
should 比must 和ought to 语气更加委婉。
例句:You should brush your teeth before you go to bed.你在睡觉前应该刷牙。
You shouldn't watch TV every day.你不应该每天看电视。
2.通常用来表示现在或将来的责任或义务。
例句:Children should obey their parents.孩子们应该听从他们的父母。
We should respect the old.我们应该尊敬老人。
3.表示推断，意为“应该；可能”。
例句:They should be there by now，I think.我觉得现在他们应该都已经到了。
4.用于第一人称疑问句，询问对方的意愿，表示说话人的一种谦逊、客气、委婉的语气。
例句:Should I open the window? 我可以打开窗户吗？What should we do now? 我们现在该干什么呢？5.表示某种感情色彩，意为“竟会”，常用于以how, why开头引导的特殊疑问句中。
例句:Why should you be so early today? 你今天为什么会如此早？二、反身代词1.反身代词的构成反身代词是一种表示反射或强调的代词。
它由第一人称、第二人称的形容词性物主代词和第三人称代词的宾格加词尾-self或-selves构成。
