式(be 用 were)

主语＋should/

If the new safety system had been put to use，the accident would never have happened.
要是新的安全系统被投入使用的话，这起事故就不会发生了。

如果你没有把地图丢了的话，我们现在就回到旅馆了。
Grace doesn't want to move to New York because she thinks if she were to live there，she
wouldn't be able to see her parents very often.
格蕾丝不想搬到纽约，因为她认为如果住在那里，她就不能经常看到她的父母了。
[易错提醒] (1)如果在表示虚拟语气的 if 从句中含有 were，had 或 should，可将 if 省略，
然后将 were，had 或 should 移至主语之前。
(2)如果主句和从句是对不同时间的事实的虚拟，则被称为错综虚拟语气。此时主句常
有明显的时间状语。
二、含蓄条件句的虚拟语气
有时假设的条件不通过条件状语从句表达出来，而是隐含在某些词或短语中，或隐含在
上下文中，这叫含蓄虚拟语气。常用的这类词或短语有：without(要是)没有；but for 要不是；
otherwise/or 否则等。
—Do you have Betty's phone number?
——你有贝蒂的电话号码吗？
—Yes.Otherwise，I wouldn't have been able to reach her yesterday.
——有，不然我昨天就联系不上她了。
Many of the things we now benefit from would not be around but for Thomas Edison.要不
是托马斯·爱迪生，我们现在从中受益的很多东西就不会存在。
三、 虚拟语气在从句中的运用
1．在名词性从句中的运用
(1)在表示要求、命令、建议、请求等动词后的宾语从句中，以及这些动词的名词形式
后面的同位语或表语从句中的谓语动词用“(should＋)动词原形”。常见的此类动词：一坚持
(insist)、二命令(order，command)、三要求(require，demand，request)、四建议(suggest，advise，
propose，recommend)。
She suggested that Dale join the debating team，believing that practice in speaking could
give him the confidence and recognition that he needed.
她建议戴尔参加辩论队，她认为辩论队里的演讲练习会给予他所需要的信心和认可。
He insisted that the problem (should) be discussed at the meeting.他执意要求在会上讨论
这个问题。
My desire is that we (should) not quarrel over such things again.
我的希望是我们不再为这样的事情争吵了。
[易错提醒] 当 suggest 作“暗示，表明”，insist 作“坚持认为”讲时，从句要用陈述语气。
(2)在“It is/was＋adj./done＋that...”句型中，从句中的谓语动词用(should)＋动词原形。常
见的形容词或过去分词有：important，necessary，strange，suggested，ordered，advised，requested，
demanded 等。
It is necessary that we (should) clean the room every day.
我们每天打扫房间是有必要的。
It is required that middle school students (should) take at least one hour's exercise every
day.
中学生被要求每天至少进行一个小时的锻炼。
(3) wish 后的宾语从句中的谓语可用一般过去时，had＋过去分词和 could/might/would
＋动词原形，分别表示与现在、过去相反的情况和与将来情况可能相反。
I wish that I had met that film star yesterday.
我希望昨天见到那个影星。
Ellen is a fantastic dancer. I wish I danced as well as her.
埃伦是一位了不起的舞蹈家。要是我能跳得像她一样好那该有多好啊。
(4) would rather 所接的宾语从句中，从句的谓语如果表示现在或将来要发生的动作，从
句用一般过去时；如果表示过去发生过的动作，从句用过去完成时。
We would rather our daughter stayed at home with us，but it is her choice，and she is not a
child any longer.
我们宁愿女儿待在家，陪在我们身边，但是选择权在她手上，毕竟她不再是个孩子了。
2．三个固定句式中的虚拟语气
虚拟情况
句式
虚拟现在 虚拟过去 虚拟将来
if only 引导的条
件句及感叹句
过去式
had＋
过去分词
would/
could/might
＋动词原形
as if/though 引导的表语从
句及方式状语从句
过去式
had＋
过去分词
would/
could/might
＋动词原形
It is (high)
time that...
过去式或 should＋动词原形
It was John who broke the window. Why are you talking to me as if I had done it?
打破窗户的是约翰。为什么你说得好像是我打破的似的？
It is high time that we took/should take some measures to solve the problem.
确实到了我们采取措施解决问题的时候了。
Look at the trouble we are in. If only we had taken our teacher's advice！看看我们所处的困
境，要是我们当初听从老师的建议该多好！
[易错提醒] 当 as if/though 引导的句子所叙述的是真实的或极有可能发生或存在的事
实时，从句要用陈述语气。
【技法点拨】
语法填空的一个完整句子中若没有别的谓语动词，或者虽然已有谓语动词，但需填的动
词与之是并列关系时，所给动词就是谓语动词，就要考虑动词的时态和语态，还要注意主谓
一致和虚拟语气。
