高中英语常考的动词不定式完成体的特殊用法

表示“意图，打算”之意的动词如hope，wish，expect，think，suppose，want，plan，agree，mean，try等用过去时，后接不定时完成时做宾语时，表示想做而未做成的事情。这种意义也可用这类词的“过去完成时 + 不定式的一般式”来表达。例如：

We wished to have put out the fire in thirty minutes.(= We had wished to put out the fire in thirty minutes.) 我们本打算半小时就把火扑灭的。(结果没有)

The engineers planned to have removed the temple before the dam was completed.(=The engineers had planned to remove the temple before the dam was completed.) 工程师们决定大坝建成之前把那座寺庙移走。
