问题描述:

谁是先行词Sports games are one of the most important factors____to raise people's national identity.
A.helps B.help C.that help D.which helps
我觉得应该C和D里面选?求详解

先行词是物的情况,一般来说that ,which都可以用,但是也有特殊情况,比如说这个例子,先行词被*修饰,那么就只能用that了哦哦,那如果是Sports games are the important factors ____ o raise people's national identity.这句话该怎么做?除了特殊情况跟,一般which that都可以互换,你把*去掉当然可以俩个都可以用
