Respuesta :
The answer to your question is D.
A and B are irrelevant in representing the admiration she has for her mother's style of English.
C and D are a bit tricky. D would be the best choice. D elaborates on why she thinks about her style of english and explains how it was nice.
Remark
It is so much D, that there is almost no point in describing why it can't be A B or C. Amy Tan is an excellent writer, so that anything says about the nature of language should be read carefully and taken very seriously. What she learned from the way her mother spoke, was powerful even though limited. It was graceful although if you are a linguist ( a scholar of languages), you wouldn't know where to start in telling what was wrong with her syntax (the way she put language together). What Amy Tan saw went far beyond all the grammar rules her mother didn't know, or didn't use if she did know them. She had a poetry in her that would be hard to find anywhere else. She had something her daughter's quick ear was able to praise because her mother had the gift of knowing and the gift of a wisdom that cannot be learned anywhere but by living a life deeply.
The other three answers don't convey the marvelous heart felt praise the daughter gives her mother. If you read nothing else carefully tonight, read the fourth answer again.
Thanks for posting. This was a real joy to discover.
