题目

—The weather has been very hot and dry. —Yes.If it had rained even a drop，things would be much better now! And my vegetables ________． A．wouldn't die  B．didn't die C．hadn't died  D．wouldn't have died 答案：D　考查虚拟语气。第二个说话人的if条件句是选择的关键。如果当时下一点雨，现在的情况就好得多了！我的蔬菜也就不会死了。过去没有下雨，所以我的蔬菜干死了，也是发生在过去。故表示与过去情况相反，而将句子还原则为If it had rained even a drop，my vegetables wouldn't have died.
