词义辨析

act as，act like

• 乍然看来，act as和 act like是两个同义短语，在涵义上无甚区别可言，其实不然。
• act as意思是“充当”、“担任”，相当于 serve as，可与人或物词如：doctor、director、interpreter、guide、coach、 teacher、go-between、furniture、tools等字搭配使用。as是连词，引导一个省略了谓语的状语从句。例：This herb can act as an antidote against snakebite．这种药草可以用作蛇咬的解毒药。
• act like意思是“行为像”、“举动像”，相当于英语的 to act in the manner of，它常与人或动物名词连用。like是介词，其后接宾语。
