我们一起看何以笙箫默吧，别做梦了，赶紧来看看高考考什么吧。
考情分析：
2016考宾从，2015定从，2014定从，
2013宾从，2012宾从及主从
结论：高考高频出现定从和宾从
that：2016+2015+2014 which：2015+2014+2012
what：2013+2012+2012 where：2016
结论：高考高频出现that， which， what

高考新宠：where（关系/连接副词）
that在定从中用于先行词指人或物，从句缺主语或宾语时。
注意：定从在介词后或有逗号与主句分开时，不能用that。
that在名从中用法：
that引导名从时只起引导词的作用，不做任何成分，也没有具体的含义。
总结which, that和what的用法：
What在名从中用于从句缺主语或宾语，缺“什么”之义时
跪求你一定要记住：What不能引导定从。
Which在定从中用于先行词指物，从句缺主语或宾语时。建议前面有介词或逗号时用。
Which在名从中表“哪一个”，名从几乎很少用到which。
