能共用的地方——只能用which，不能用that
例如：
Students living in their own homes would live a more comfortable life and have more opportunities to communicate with their parents, which has a beneficial impact on the development of their personalcharacter.
再如：
Television, the most pervasive means of entertainment for the average public, is advancing towards an entirely new era, an era of extraordinary sophistication and versatility, which is likely to reshape the world.
在这两句话中，which都是不可以用that取代的，因为which在文章中指代的是前面的整句话，所以which后面的谓语动词用的也是单三形式。当which在从句里面用来表示前面整句话造成的影响时，which前面要用逗号，谓语动词用单数。
