Module2EnvironmentalproblemsUnit3Theenvironment第2课时Reading·下册·要点精讲Withoutit,theEarthwouldbethesameastheMoon—coldandlifeless.没有它，地球将会像月球一样冷冰冰的，毫无生命迹象。本句是虚拟语气。虚拟语气是说话者用来表示假设或难以实现的情况，而非客观存在的事实。它所陈述的是一个条件，不一定是事实，甚至可能与事实完全相反。使用虚拟语气时，若表示与现在事实相反，则从句要用一般过去时(be用were而不用was)，主句用would/should/could/might+动词原形。句中的without…相当于ifthereweren't…。如：Iftherewerenoairorwater，therewouldbenolivingthingsonEarth.如果没有空气或者水，地球上就不会有生物。(事实:地球上既有空气也有水)WithouttheSun,nothingwouldgrow.没有太阳，什么东西都不会生长。.(
