ការពន្យល់
A 16-character sentence, almost twice as long as at the beginner level, so do not memorise character by character; hear it as meaning chunks: 我每天早上七点半 / 坐地铁 / 去公司上班. The order is subject + time + means (坐地铁) + where and what — Vietnamese learners tend to move the time after the verb, so repeat it in the order you heard. 七点半 is qī diǎn bàn; 点 is a third tone before a fourth, so only the low half is said. 地铁 (dìtiě) and 上班 (shàngbān) start with falling tones: drop your voice firmly. Breathe after 七点半 and do not pause between 公司 and 上班.
