Can I not just say, "我喝什么？"
That how i answered and said i was correct.
Im wondering this also
This is kinda a weird thing to say... Shouldn't you know what you drink?
Would the English be better if it was "What am I drinking?"
It's weird, but I guess it teaches you the grammar. I could see it being useful if you were given a drink at a meal in China (hopefully by a trusted friend, guide, or restaurant), where you wanted to know what it was.
Why would you use 呢 for this question？I know 吗 is generally for yes/no questions, but what's the rule on using 呢?
There's no need for 呢. 我喝什么？was what I got and it was correct.
What function does 呢 serve in this sentence?
It's not necessary, but having it can help emphasize that the sentence is a question.
I wrote (somewhat hopefully), "what drink I?" it didn't work :-( Still, we learn
That is not the right grammer, so I guess that's why you got it wrong... Oh well.
Surely it would be better to learn "What do you drink?"
