记忆技巧Memory Tip
想象光线进入水或玻璃时被“折断”了一下，方向偏转，这就是折射。
语境与语域Context & Register
语域：formal 常见场景：physics、optics、ophthalmology refraction 通常用于物理、光学和眼科等正式或专业语境，多出现在教科书、学术论文或检查报告中；日常口语中较少使用。
发音与拼写Pronunciation & Spelling
fraction, diffraction, traction, action, reaction, and attraction all rhyme with refraction: each ends in the stressed sound /ækʃən/ (reaction and attraction simply have an extra syllable before that sound). Beware the lookalikes reflection /rɪˈflɛkʃən/ and flexion /ˈflɛkʃən/, which end in /ɛkʃən/, not /ækʃən/, so they do not rhyme with refraction.
