bemadeupof与consistof的用法有什么区别?

Question

be made up of 与 consist of 的用法有什么区别?

Answer 1

be made up of =consist of 由……组成
consist of 由...组成的.相当于be made up of .后面是加组成的成分.
例如:This necklace consists of gold and diamond.
注意,consist 本身是一个不及物动词,不能采用被动语态.
be made of/from...都是表示由.制成的.
但是be made of 是可以看得出原料的.例如
The desk is made of wood.
而be made from.是不可以看出原料的.例如
Paper is made from wood.
