be made up of ,be made with ,made of ,made from 区别

1个回答

  • e made up of 由.组成

    be made with 用.制作

    made of 和made from多用被动语态,即前面加be

    be made of ...

    该短语表示“某物由……制造而成”(从制成品中可以看出原材料).如:

    The bookshelf is made of wood.

    这个书架是由木头制成的.

    be made from ...

    该短语也表示“某物由……制造而成”(从制成品中一般看不出或难以分辨出原材料).如:

    Paper is made from wood and bamboo.

    纸是由木头和竹子制造而成的.

    be made of 和made of 以及be made from 和made from意思分别相同,前面加be 的表示被动,仅此而已
