或者说： Can you speak Chinese? (这样要委婉一些)

How is your Chinese? Do you understand it? Actually I can't speak English,somebody helped me translate my message on th Internet.

【人工翻译】How about your Chinese (level)?O(∩_∩)O哈哈~，就这么简单，记得采纳哟~！

You can teach me Russian and I can teach you English.

your Chinese is very good.就可以了简单明了

Your Chinese is really good!Your Chinese is quite good!Your Chinese is just as good as a Chinese It's unbelieveable that your Chinese is so good

how are you ?怎么是你？How old are you?怎么老是你？如果每句话都是单词堆砌起来翻译，那相信每个人都是高手了。

How do you think so?

可以这样问：Could you tell me if you can speak Chinese?

How do you do? 回答有I 'm fine，I 'm good 。how do you do是相对比较正式的问候，常见于60、70年代，现代人见面很少说这句话了。对于how do you do 的回答有三种方式：1、中规中矩的回复：如果有人问你How do you do？你也可以同样问那人how do you do ?2、可以用how are you？
