【问】 “He is already on the wrong side of forties.” “It's about time he_______himself a wife andsettled down. ”
 A. finds B. should find C. found D. had found(TOEFL，73. 6)
 书上给的答案为C(found)。但我不明白这里为什么要用过去时。难道它是表示过去的事情吗?
 【答】 这里的found并不是陈述语气的过去时，而是假设过去时(虚拟语气过去时)，因而它表示的并不是过去时间，而是表示现在或将来的时间。这种用法主要用于表示说话人的观点或信念，它意味着讲话的此时此刻动作并未发生，而说话人希望其尽快发生并往往含有动作早该发生的意思。
