C.
翻译:玛丽来中国之前学了点汉语.
这个题之所以用过去完成时是因为,这个学汉语的动作发生在她来中国之前,表示的是过去的过去的动作.后面来中国的动作用了came,是过去时,所以learn的动作就是过去的过去,用had learned.

C选项应该是had learned吧，应该用过去完成时，因为学中文这个动作发生在came这个过去式之前

选A吧，因为Mary是第三人称，所以要用单三结构has。
意思是：Mary在来中国之前学了一些中文

mary had learned some chinese before she came to china.
玛丽在来中国之前学了一些汉语
考察的是过去完成时
