在這里呢，would 后接完成式除用于構(gòu)成過去將來完成時外，它還有其情態(tài)動詞用法的一面。具有情態(tài)意義，比較表示推測或猜想等。請看接下來的例子。
Only somebody with a small mind would have refused to help others.
只有心胸狹窄的人才不肯幫助別人。（這里的would表示推測意義）
Few men would have bared their soul to a woman as he had.
很少有男人能像他一樣對一個女人敞開心扉。（這里表示懷疑的意思）
I’m surprised you didn’t like the book. I would have thought it was just your piece of cake.
你居然不喜歡這本書，我本來還認為這正符合你的口味呢。（表示過去的想法）
My sister would have driven me to downtown to go shopping, but we decided it would be faster and more convenient by train.
姐姐原本要開車送我去市中心購物，可我們后來還是覺得坐火車要更快捷和方便（表示過去的想法）
The scar added interest and mystery to her face that otherwise would have appeared too numb and plain.
這個傷疤為本來就平淡無奇且麻木的臉上增添了一絲神秘和生趣。（表示未曾發(fā)生的情況）
What interesting job have you found?” her mother asked him; she knew he would have been thinking about it.
你找到什么有趣的工作啦?”他的媽媽問道。她知道他一定會一直考慮這件事的。
過去將來完成進行時態(tài)雖然不常用，但是與其他的時態(tài)有著這樣那樣的交集，在理解文章意思的時候很容易產(chǎn)生理解偏差，所以更多的還是要童鞋們課后自己慢慢復習咀嚼和消化咯。?
