Question

— You           your ideas at the meeting in a different way.
--- Thank you, but I was too angry then.

A．must express	B．could express
C．could have expressed	D．must have expressed

Answer 1

C

解析試題分析：句意：—在會(huì)議上你本來可以用不同的方式表達(dá)你的想法。---謝謝你，但那時(shí)我太生氣了。 由but I was too angry then 可知是過去時(shí)態(tài)，所以過去能夠做而沒有做的，用could have done表示。must have expressed表示對(duì)過去的肯定推測(cè)。A、B都是對(duì)現(xiàn)在時(shí)間的推測(cè)。故選C。 
考點(diǎn): 考查情態(tài)動(dòng)詞的用法。
