appreciate sb doing sth是对的，appreciate sb for doing不对。
例句：We appreciate your helping us.
谢谢你帮助我们。
词语用法：v. (动词)
1、appreciate的基本意思是“高度评价某事物”,可表示对某事物理解深刻而能鉴赏或欣赏其价值,特别是美学价值,有时还可表示非常喜欢、非常感激的意思。引申还可表示“增值”。
2、appreciate作“感激”“重视”“体会到”解时,是及物动词,可接名词、动名词(但不接动词不定式)作宾语,也可接that从句。可用于被动结构。appreciate作“增值”解时是不及物动词,作“使增值”解时是及物动词。
3、appreciate后可接that从句。美国人习惯在appreciate后直接加that，而英国人则习惯在that前加上the fact。
例句：I appreciate that the plan has worked well.
I appreciate the fact that the plan has worked well.
4、appreciate后不可接不定式，可以接动名词。
例句：He appreciates being advised.
他很感激得到了建议。
5、有时，appreciate后带动宾语it最好不讨省略掉。
I shall appreciate it if you will give me his address.
