as与like的区别
比较以下句子,你就明白了:
1 He works hard like me (简单句)----他工作努力,就像我一样。
2 He works hard,as I do (这不是简单句,是方法状语从句)-------如果是方法状语从句,AS就成了连接词,后面就必须是句子了(所谓句子就是要有主语+谓语(+其它成分)。
我相信,你已经懂了。 祝你学习进步
like和as的区别
as与like是英语中常见的两个词,他们的语义和用法很多.在语义上者两个词都可以当"像......","正如......"讲,说明人与人、物与物、动作与动作、状态与状态之间的相似之处。但其语法结构却是不一样的。
一、当“像”讲时,语法结构的不同之处是:
1、as作连接词。她引导比较状语从句和方式状语从句,而且这两种从句通常为省略句。例如:
1、She is a fine singer, as her mother used to be.
2、There is as much water in this cupas in that one.
2、like作介词。例如:
3、My sister isn''t much like me.
4、The robot can''t work like man.
如果需要加强语气,再这两个词之前加上just之类的词即可。例如:
5、All the plants and animals need air just as they need water.
6、Mary goes to school at seven every morning just like her brother.
含义不同之处是:
(1)like只是单纯表示比较,而且通常不是同类事物进行比较:
7、The ship looks like a high building.
8、The sky was like ink over my head.
(2)as可表示同类事物比较。
9、This ship is as long as that one.
二、当“正如....”意义讲时,语法结构的不同之处是:
(1)as作关系代词或关系副词、引导定语从句。
as 在这样的句子里指全句所谈到的内容,引出非限制性定于从句或限制性定语从句的固定搭配,在从句中一般做主语或宾语。例如:
10、Metals have many good properties, as has been stated before.
11、As we said before, you have done a good job.
I have never met such a kind man as Jack.
This book is the same as that one in its cover.
(2)like作介词。
12、She, like thousands of others, is fascinated by this work.
三、as与like有时可以换用。
(1)在非正式的美国英语中like可用作连词,代替as.例如:
13、Nobody loves you like I do, baby.
(2)在非正式的文体中,like,常被用来代替as if.
14、Duke said:"You feel like you could reach out and touch it (the space)."
四、as常用于下列词组:在as you know ,as we agreed, as you suggested 这些词组中,as的实际意义不是比较,也不是相似,而是同一事物或人之义。例如:
as you know 的意思不是you know somthing like this ,而是you know this.
15、As he knew, she wasn''t much at letter-writing.
16、As all his friends agree, he was unusually warm-hearted,loving and generous.
在非正式问题中,有时可以在这种词组里用like,但在受过教育的人所使用的英语中不多见
以下分析as与like的异同:
(其中第一点为区别as与like都作“像”的解释的方法)
1.当as和like都表示人或物的外貌、形态、动作的相同之处。译作“同……一样,如,像”时,
as是连词,后跟从句;like是介词,后跟名词或代词
e.g.
(1)He works as others do.=He works like others.他像其他人一样工作。
(2)You should do as he tells you.你应该像他告诉你的那样去做。
You should do like him.你应该像他那样工作。
(3)She is a teacher,as her mother is.她是一位老师,同她母亲一样。
She isn't much like her mother.她不太像她母亲。
所以,倘若你不会判断连词与介词,首先确定as与like在句中确实是要表达“像”的意思,然后观察所用的是单词(包括短语)还是句子,就可以根据两者的差别决定该用哪个词。
而当as在句中不表达“像”,只表达“作为”的意思时,之后就可以跟单词(包括短语)了。(见第二点)
2)as作介词时,表示“作为”,后跟名词
e.g.(1)The room is used as a reading room.这间屋子被用作阅览室。
3)like作形容词时,在句中作定语或表语。其中作表语时可用very修饰。
e.g.(1)The two brothers are very like.兄弟俩长得很像。
此时虽然like仍表达“像”,但决不会与as混淆了。
最后作个比较:
He spoke to her like her father.他像父亲那样同她说话。(他不是她父亲。like表达“像”)
He spoke to her as her father.他以父亲的身份同她说话。(他就是她父亲。as表达“作为”)
