Question

---It’s very kind ____you_____ help me complete the difficult job.
--- You’re welcome.
A. to; for                 B. for; of             C. of; to

Answer 1

C

解析試題分析：to到，不定式符號(hào)；for為了；of……的。句意：幫助我完成這項(xiàng)艱巨的工作，你太好心了。——不客氣。固定句式It’s adj of sb to do sth，故選C。
考點(diǎn)：考查固定句式It’s adj of sb to do sth
