四、特別說明
有些動詞的過去時，如：expect, hope, intend, plan, wanted 等一般過去時，后接不定式的完成時；或它們的過去完成時接不定式的一般式，都可表示過去未曾實現(xiàn)的意圖、打算或希望。如：
I hoped to have been invited to his wedding party. —I had hoped to be invited to his wedding ceremony. 我本希望他來邀請我參加他的婚禮。
I intended to have joined their games. —I had intended to join their games. 我本打算參加他們的比賽。

5. I thought Jim would say something about his school report, but he ______ it.
A. doesn’t mention B. hadn’t mentioned C. didn’t mention D. hasn’t mentioned
