为什么This machine is___metal.填made of而不填make of
为什么This machine is___metal.填made of而不填make of
为什么This machine is___metal.填made of而不填make of
表示被动的意思
被动。机器被用钢铁做成 be made of 是被动用法
被动用法：be made of。
句子翻译可为：这个机器是用金属做成的。
被动。机器被用钢铁做成 be made of
也可以改成：metal make of this machine.
这个如果这样说的话就是固定搭配，但是如果就是究其根本就可以理解为，这个机器是被金属做成的，就是说这个机器与其材料之间是有一种被动的关系的，所以这里一定要用made
is后面跟V-ing形式
所以要用made of
be made of是固定词组，”用．．．制成的””被．．．制成的”（原材料可见）例:The table is made of wood.
原材料不可见be made from 例：Paper is made from wood
被动语态结构be动词＋动词过去分词
