选择题
Without your timely help, we ________ in big trouble that day.
A．would have been
B．would be
C．had been
D．were
答案
A
题目分析：考查虚拟语气。本题的虚拟语气是通过介词without(要不是…；如果没有…)表现出来的，本句的时间状语是that day是一个过去时的时间状语，故使用“情态动词+have done”的形式来表示。句意：要不是你及时的帮助，那天我们就会有大麻烦了。故A正确。
点评：without虚拟语气的用法：
1. 与现在事实相反：Without air, man couldn't exist on the earth.没有空气的话，人类将不能在地球上生存。
谓语动词：would/could/might (not) do sth.
2. 与过去事实相反：Without your help, I would have failed the exam last week.没有你帮助的话，我上周考试可能就通不过了。
谓语动词：would/could/might (not) have done sth.
3. 与将来事实相反：Without your ticket, I wouldn't be able to go to the concert tomorrow.要是没有你的票的话，我明天就不能去听音乐会了。
谓语动词：would/could/might (not) do sth.
