made of和made from如何区别使用？

make from和make of的区别

make of与make from两者都常用在被动语态中,表示“某物由.构成的”.它们的区别是一个能看得见原材料，一个看不见原材料

of 能看的见原材料，the desk is made of wood.

from看不见原材料，the paper is made from wood.

1、be made of“由…构成”,能看出原材料,像桌子由木头制成,刀子由铁或金属制成,很明显看出原材料,如：

①The desk is made of wood.

②The knife is made of metal.

2、be made from“由…构成、制成成品”,被制成的东西看不出原材料,像纸是由木头制成的,这就看不出.

如：The paper is made from the wood.
