如题所述
我们常常会用be made in和be made of来表示制造，这两个短语在含义和用法方面存在着区别，具体如下：
一：含义解释
be made in 英 [bi meɪd ɪn] 美 [bi meɪd ɪn] 在……地方制造;在…生产或制造;由某地制造
be made of 英 [bi meɪd ɒv] 美 [bi meɪd əv] 由...制的
相同点：都可以表示"制造"。
不同点：be made in侧重于制造的地点；be made of侧重于被……原料制造。
二：用法区分
be made in：后面跟制造的地点、国家等；Made in China：中国制造；This silk was made in Hangzhou. 这丝绸是杭州织造的。
be made of ：指能看得出来啥做的，比如桌子是木头做的，电话是塑料做的等等； This kind of cloth is made of wool. 这种布料是羊毛的。 All the furniture is made of wood. 所有的家具都是木头做的。
三：典型例句
1、be made in

——Paper is made in a paper mill.

2、be made of
