I appreciate ________ to help me, but I am sure that I can manage it myself.
A、that you come
B、you to come
C、your coming
D、how you come
【正确答案】：C
【题目解析】：本题考查动名词的用法，动名词前有时可有一个物主代词或名词所有格来表示它逻辑上的主语。此外，appreciate后必须用动名词或动名词的复合结构作宾语，它与所接动名词一般为同时发生的两个动作，如：I would appreciate your keeping it a secret．如果你对这件事情保密的话，我会非常感激的。故C为正确答案。
