Questions & Answers about wǒ zhèngzài diǎngē.
正在 marks an action as in progress right now. It is similar to be doing in English.
So:
- 我正在点歌。 = I am selecting/requesting a song right now.
A useful comparison:
- 我点歌。 = I select/request songs / I select a song / I’m selecting a song.
- This is more neutral and depends on context.
- 我正在点歌。 = I am in the middle of selecting/requesting a song right now.
Chinese usually follows Subject + Time/Aspect Marker + Verb + Object.
In this sentence:
- 我 = subject, I
- 正在 = progressive marker, in the middle of
- 点歌 = verb-object phrase, select/request a song
So the structure is:
- 我
- 正在
- 点歌
- 正在
- I
- am
- selecting/requesting a song
- am
This is very normal Chinese word order.
