单元语法精讲
Ⅰ.反身代词
1.概念及组成:反身代词是一种表示反射或强调的代词。它的基本含义是:通过反身代词指代主语,使施动者把动作在形式上反射到施动者自己。因此,反身代词与它所指代的名词或代词形成互指关系,在人称、性质、数上保持一致。
人称
数
第一人称
第二人称
第三人称
单数
myself
yourself
himself/herself/itself
复数
ourselves
yourselves
themselves
2.用法
(1)反射用法
这种用法通常表示反身代词与句中的主语是同一人。它在句中作宾语,不能省略,否则该句是一个意义不完整的错句。
eg:I teach myself English.我自学英语。
(2)强调用法
反身代词在强调用法中表示强调,即用来加强某个名词或者代词的语气,可译成“亲自”、“本人”。此时,它在句中作同位语。即使去掉,也不影响句子的完整性。
eg:You must do it yourself.你必须自己做。
注意:反身代词不能作主语,但可作主语同位语,放在主语后或句末。
eg:I went to the cinema myself.我自己去了电影院。
【拓展】含反身代词的常见短语:
learn sth.by oneself 自学
enjoy oneself 玩得开心
help oneself to 随便吃
leave sb.by oneself 把某人单独留下
improve oneself 提高自己
look after oneself 照顾自己
Ⅱ.should的用法
should是情态动词,意为“应该,应当”,可用于各种人称,无人称和数的变化,也不能单独作谓语,只能和动词原形连用。其否定形式为shouldn't。变—般疑问句时,should应提到主语之前。其用法如下:
(1)表示责任和义务、劝告和提出建议。
eg:We should learn English well.我们应该学好英语。
You should get enough rest.你应该得到足够的休息。
(2)表示命令和要求,语气比较强烈。
eg:You shouldn't be late.你不应该迟到。
(3)表示预测和可能性。
eg:He should know me.他应该认识我。
