@形容過去如果怎麼樣,就可能發生什麼事If+S+had+V(過去分詞),S+would/might/could+have+V(過去分詞)依題, I would have gone with you to see the movie had it been at all possible, but I was fully occupied the whole of last week(整個上周,明題是過去,故選過去式).

would have p.p. = would 原V 的過去式因此須選 is 的過去式 was(B) had p.p. 是 have p.p. 的過去式通常用作"過去式的過去"
