China's rapid rise spurs Americans to learn Chinese

[Glenn]

The usage of "在" is ok here, "在" has the meaning of "right now", see:
你在干什么? What are you doing?
我在看书. I'm reading.
I think "我在慢慢地学中文" would be better.

I thought that might be the case, but I've only seen it next to the verb from what I can remember, so I went with that. 謝謝你，quiet sunshine小姐!

不客气!
Hm, we did exercises like extending or contracting sentences when we were kids, I think it's a useful way to make sentence structure more clear.
我在学中文==>我在<慢慢地>学中文
我在看书===>我在<认真地>看书

我在要再学中文 !

Lexico san, this sentence has a small problem.
我要再学中文,or 我现在要再学中文 is ok.
Your grammar knowledge is richer than mine, so I'm sure I don't need to struggle to use my poor English here.

Thanks for all the learning you give me. Some things I never got right, so I'm glad I get those corrected now, not never.
