当条件从句使用“should+动词原形”这样的谓语时,主句谓语除可用“should (would,could,might)+动词原形”这样的虚拟语气外,也可用直陈语气或祈使语气：
If it should rain tomorrow,don’t expect me.万一明天下雨,就不要等我了.（祈使语气）
If I should see him,I’ll tell him.万一我见到他,我就告诉他.（直陈语气）
Should there be a power failure,the hospital will run on electricity from its own generators,which can operate for 200 hours.
万一停电了,医院就会从它自己的能够运行200小时的发电机那里继续供电
如果改为were there to be=if there were to be 表示与将来事实相反,主句则需要用would+v.你的句子就不对了.
the hospital will run on electricity from its own generators← 也许这句话不是虚拟语气
只有前面半句话是虚拟 后面的可能是确实发生了
如果不是这个句子错了 也许就只能这么解释了
不过前面的确实是个对将来的虚拟 were to do 倒装。。
will 改为would，虚拟语气，与将来事实不相符。
