Question

It’s very nice ______ you to help me with the hard work. ______!

A. for, I very thank you      B. for, Thank you very much

C. of, I thanks you       D. of, Thanks a lot

Answer

D

【解析】

试题分析：句意：你真好来帮助我做这项艰苦的工作，多谢了。这里是固定句式it is+形容词+of/for+sb to do sth,当形容词表示人的性格或品性的词时用介词of,否则就用介词for，这里nice表示人的品性，所以用介词of；thanks后不能跟人称代词，故排除C。故选D。

考点：考查固定句式及交际用语。
