Question

—I regret _____ you that Mary was badly injured in the accident.
—I can hardly believe my eyes. She is always so careful.

A．informing

B．having informed

C．to inform

D．to have informed

Answer 1

C

試題分析：考查regret用法。動(dòng)詞regret有兩個(gè)短語(yǔ)：regret to do sth遺憾要做某事；regret doing/having done sth遺憾做了某事；句意：我很遺憾地告訴你Mary在事故中受了重傷。故C心中卻。
點(diǎn)評(píng)：要注意該詞連接不定式和動(dòng)名詞所表示的不同的意義，要區(qū)別事情未做還是已經(jīng)完成。這樣的用法在日常學(xué)習(xí)中要注意積累的歸類(lèi)。
