as与like在语义上两个词都可以当"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,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,引出非限制性定语从句,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. 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。
