“使用中文”就是"use Chinese"，有什麼不可以的？

用中文解說這個句子
= use Chinese to explain this sentence
= explain this sentence in Chinese

用中文表達自己 = use Chinese to express yourself
用中文學日文 = use Chinese to learn Japanese

I think you are looking for the answers you wanted. But here are my comments:

1. "use Chinese" is indeed OK.
Example:
Can I use Taiwanese in LAX?

2. Also correct is "in Taiwanese".
Do I need to write the report in Taiwanese?

例句
1.使用中文說明 Please elaborate in Taiwanese.
2.只因為我說中文就瞧不起我 They looked down on me, just because I spoke in Chinese!

Also, OK:
Please use Taiwanese to explain to more.
They looked down upon me for I could not use Taiwanese.

使用什麼語言是用: in + 語言, 所以使用中文就是 in Chinese
說什麼語言可直接說 speak + 語言
1. to explain in Chinese
2. look down on me just because I speak Chinese
(look down on someone 是瞧不起的意思)
