有没时态的区分?
答
be made of 是用什么材料做成的
be made for做来干什么用的
答
be made of 是用什么材料做成的
be made for做来干什么用的
made本身就是make的被动态!因为东西都是被动处理的啊.
be就根据实际句子的需要可以用am,are,was,were
答
你是想知道be made of 与be made from 的区别吧,be made for是:最适宜的
be made of 与be made from 的意思都是“由.制成”的意思.
be made of是直接能看出原材料的
例:This book is made of papers.这本书是纸作的.
be made from 是不能从肉眼直接看出原材料的.
例:The paper is made from wood.纸是由木头制成的.
答
是be made from 吧?
前者是由…制成 看得出材料
后者是看不出材料
be made for 为…制造(我不太确定)
