【英语语法】like和as的用法对比
as 和 like 在汉语中都译做"像",但字面下的隐含意思是不同的。下面小编整理了一些相关信息，供大家参考!
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：
She is a fine singer,as her mother used to be.
There is as much water in this cupas in that one.
2、like作介词.例如：
My sister isn''t much like me.
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：
All the plants and animals need air just as they need water.
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：
The ship looks like a high building.
The sky was like ink over my head.
(2)as可表示同类事物比较。
This ship is as long as that one.
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、引导定于从句.
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,在从句中一般做主语或宾语.例如：
Metals have many good properties,as has been stated before.
As we said before,you have done a good job.
(2)like作界词.
She,like thousands of others,is fascinated by this work.
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：
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.
Duke said:"You feel like you could reach out and touch it (the space)."
like常用短语搭配like as 正如, 如同
like that 那样地 类似地 一概如此, 都是那样 非常友好亲密
and the like 等等,云云;…之流
like it or not 不管你真喜欢不喜欢
as like as not 大概,多半,很可能
be like 相像
like this 这样地 如此
such like adj.象这类的
the like phr. 类似的东西
Like for like 一报还一报;以牙还牙
