1. 镜子
    A mirror is a flat piece of glass which reflects light, so that when you look at it you can see yourself reflected in it.

    e.g. He absent-mindedly looked at himself in the mirror...
           他心不在焉地看着镜中的自己。
    e.g. He checked his mirror and saw that a dark coloured van was immediately behind him.
           他看了一下后视镜，发现一辆深色货车紧随其后。

2. 反映;再现;与…相似
    If something mirrors something else, it has similar features to it, and therefore seems like a copy or representation of it.

    e.g. The book inevitably mirrors my own interests and experiences...
           这本书不可避免地反映出我个人的喜好与经历。
    e.g. His own shock was mirrored on her face.
           他和她面面相觑。

3. (水)照出，映出
    If you see something reflected in water, you can say that the water mirrors it.

    e.g. ...the sudden glitter where a newly-flooded field mirrors the sky...
           刚刚被洪水淹没的田野映照出了天空，那里突然泛起亮光
    e.g. The ship would lie there mirrored in a perfectly unmoving glossy sea.
           船会停靠在那里，映衬在一片波澜不兴的湛蓝海水之中。
