Finally, my thanks go to my tutor, who has offered a lot of suggestions and comments on my paper and every page of my draft.

A. approved

B. quoted

C. polished

D. folded

答案：

A. approved

B. quoted

(答案→)C. polished

D. folded

解析：考查动词辨析。难度中等。

【解题思路】句意为：最后，我要感谢我的辅导老师，他给我的论文提出了很多批评和建议，并对每张稿件作了推敲。C项意为“推敲”,符合句意,故C项正确。A项意为“通过”，B项意为“引用”，D项意为“折叠”，都与句意不符。
