内容提要：由“绝不可以让其他任何人知道”可知选C，mustn't 表示“不允许，不可以”，语气强烈。

11．(2012·淮阳模拟)—I didn't attend the lecture yesterday.
—I________ ，either，if my mother hadn't reminded me.
    A．wouldn't B．wouldn't have    C．didn't D．hadn't
解析：考查虚拟语气。从句子中if my mother hadn't reminded me 知，此处是对过去状况的虚拟，主句应该用should/would/could/might＋have done结构，从选项中看只有B项合适(I wouldn't have 是I wouldn't have attended the lecture的省略)。
答案：B
12．(2012·莆田一模)—How much of the foreign expert's speech have you understood?
—Next to nothing.I wish I________ harder at English.
    A．worked B．had worked   C．would work D．were working
解析：考查虚拟语气。wish 后的宾语从句用虚拟语气，此处表示与过去事实相反，意思是：我希望我(过去)更努力地学习英语了。
答案：B
13．(2012·莱州质检)—Did you make it at last?
—Yes.But for your help，it________ a serious loss.
    A．would cause
    B．must have caused
    C．would have caused
    D．may cause
解析：考查虚拟语气。句意为：——你们最后成功了吗？——成功了，要不是你的帮助，我们的损失就大了。but for...要不是……。
答案：C
14．(2012·滨州质检)You ________ as well do this now, for you will have to do it first or last.
    A．need B．must C．can D．may
解析：考查情态动词may。语意：你不妨现在做，因为你早晚要做。may as well 表示“不妨，倒不如”。
答案：D
15．(2012·青岛调研)If we're to get better business growth, then his idea ________ be taken too seriously.
    A．should B．may C．can't D．mustn't
解析：考查情态动词can。从语意和用词看，本题选C，can't/can not...too 表示“再……也不为过，越……越好”。
答案：C
16．(2012·德州二模)—Oh, it is seven. Tom, it is high time you ________ to school.
—Mom, don't you remember it is Sunday?
    A．go B．went C．will go D．must go
解析：考查虚拟语气。It is high time that... 后面的从句要用虚拟语气，谓语动词通常用过去式。
答案：B
17．________ today, he would get there by Friday.
    A．Was he to leave B．Was he leaving C．Were he to leave D．If he leaves
解析：考查虚拟语气。语意：如果他今天出发以的话，那么周五之前就可以到那里了。由主句的时态及语意可知，这里是对将来事实进行假设，从句中谓语可以用were to do 的形式，从句可以省去if并将were放于句首。
答案：C
18．(2012·长沙月考)If you ________ the medicine yesterday, you ________ fine now!
    A．took；would be
    B．had taken；would have been
    C．had taken；would be
    D．took；would have been
解析：考查虚拟语气。这是一个错综条件句。条件与过去的事实相反，用过去完成时；而主句表达的结果与现在的事实相反，用would＋v原形的形式。
答案：C
19．(2012·沈阳模拟)Seeing how tired my son was, I offered to help. But my wife insisted that our son ________ the house on his own.
    A．clean B．cleaned C．cleaning D．would clean
解析：考查虚拟语气。insist 在此表示“坚持要求”，后面的宾语从句要用虚拟语气，谓语动词用“(should)＋do”的形式。
答案：A
20．35 passengers died in the bullet train accident. But for the heroic train driver, many more people ________.
    A．had died B．would die C．would have died   D．died
解析：考查虚拟语气。But for the heroic train driver 意为“要不是那个英勇的司机”，表达的是一个与过去事实相反的条件，故主句表达的结果也应该与过去的结果相反，应用would have done结构，故答案为C。
答案：C
