词义辨析

n. (名词)

phase, angle, aspect, side

• 这组词均可表示“方面”,有时可以换用。其区别是：
• aspect通常指表面的变化，尤其是不可预测的情况带来的变化，还特指因观察者的出发点变化而引起的外貌的变化；phase指事物发展变化的阶段或状态，有时也指事物的某方面的特征；side一般指两面或两面以上，得转换角度观察才能全部看清；angle则指从一个受局限或特定的角度所看到的方面。

phase, stage

• 这两个词都可指发展的阶段或时期,但stage除了与介词of连用以外还可与at连用; 另外,侧重于外观变化时用phase,不用stage。

phase，aspect，side，angle

• 这些名词均有“方面”之意。
• phase指可以对事物进行观察或描述或考虑的任何方面。
• aspect着重以特定观点对事物进行观察或考虑。
• side可与aspect和phase换用，但更着重构成事物全貌的一个或多个方面。
• angle专指从某一角度去观察、考虑事物的某个方面。

词源解说

• ☆ 1812年进入英语，直接源自现在拉丁语的phases，意为表现，表面；最初源自古希腊语的phasis，意为星星的样子。
