Question

Now 70 years old, the British physicist, Pendry can’t remember a time when he was not asking a question as a kid, joking that he ________ his parents to death.

A．should torment(折磨)	B．must torment
C．must have tormented	D．should have tormented

Answer 1

C

試題分析：考查情態(tài)動詞與虛擬語氣。句意：現(xiàn)在，70歲的英國物理學(xué)家Pendry記得兒時，總是被問同樣的一個問題，開玩笑說他一定是折磨死了他的父母。根據(jù)joking可知，事情不是真實的，用虛擬語氣。must have done一定已經(jīng)做了某事；should have done sth本應(yīng)該做某事。故選C。
