请问这个句子的语法是否正确
were there to be a power failure,the hospital will run on electricity from its own generators,witch can operate for 200 hours.
were there to be a power failure,the hospital will run on electricity from its own generators,witch can operate for 200 hours.
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.
