A.Would you be surprised
B.Were you suprised
C.Had you been surprised
D.Would you have been surprised
答案是A。 但是為什麽不選D呢？不是對過去的壹種假設嗎？求詳解~
答：這題考錯綜時間虛擬條件句。
真實情況是：I arrived yesterday letting you know beforehand. 我是昨天到的，事先告訴過妳的。現在我們見面了，妳沒有感到訝（You are not surprised)。假如我昨天到了而不給事先告訴妳，當我們現在見面的時，妳會不會很驚訝呢？主句（問題）問的是現在的情況：
If I had arrived yesterday without letting you know beforehand，woud you be surprised?
如果講的是過去的情況，當時他並不驚訝，因為我事先告訴他了，則為：
If I had arrived yesterday without letting him know beforehand，he would have been surprised.
當面問的是現在的情況。如果前面有壹句話：
You were not surprised when we met just now because I had told you about it before hand.
If I had arrived yesterday without letting him know beforehand，would you have been surprised ?
妳剛才會驚訝嗎？
所以，是去還是現在，還是為假設過去，主句是現在，還是要去理解體會句子的語境。
