【问】 请解释形容词aware与形容词conscious的区别。

【答】 aware作“意识到的”解，通常只用作表语，而conscious既可用作表语，又可用作定语：

1. They became aware of a peculiar smell in the room. (ECD)

他们发觉房间里有一股特殊的气味。

2. She is politically aware. (LDCE)

她有政治觉悟。

3. the conscious patient～The patient is aware. (CGEL)

但是，当aware作“有觉悟的”、“明智的”解时，可作前置定语。

1. a politically aware person(LDCE)

一个有政治觉悟的人

2. Would an aware，thinking person say such foolish things?

一个懂事的、有头脑的人会说这种蠢话吗?

4. He smiled to express conscious superiority. (Wells)
