1 这两个短语动词同义，都作“以……制成”讲， 如果所用原料给制成成品后，已不能识别出来，要用be made from；否则，要用be made of。be made out of类似于 be made from例如： Paper is made from rag．纸是用破布头制成的。（制成后已看不出是破布头的模样了）
This table is made of hardwood．这张桌子是用红木做的。（制成后仍能看出是用红木做的。）
At present, many things are made out of plastics. 现在许多东西都是用塑料制成的。2如果比较级最高级前面有形容词性物主代词不用加the 如:she is my best friend
