英语达人进来帮忙（关于定语从句）,
这里有三对句子：
1、The school where I study is very beautiful.
The school which/that I visited yesterday is beautiful.
2、The day when I was born is June 6th.
The day which spent with her is uncomfortable.
3、The reason why I was late is just an excuse.
The reason which/that I gave is just an excuse.
这三对句子的引导词为什么不一样啊?什么情况下用关系代词,什么情况下用关系副词啊?感觉分辨不清楚.能帮我详细分析一下这三对句子的句子成分吗?越详细越好（本人英语不好）.
引导词的不同是因为从句缺少的成分不同
例如1句（上）中，从句从句本身是完整的，在这里引导词就是关系副词，作用相当于介词加关系代词；而（下）句中由于visit是及物动词，所以可见从句缺少了宾语，因此需要一个名次，所以只需要关系代词。2、3句一样，上句都是关系副词，下句都是关系代词，解释也相似。
解释的不是很好，毕竟我也是才高中毕业，希望对你有所帮助。
教你个简单的办法，前提是你要搞清楚关系代词和关系副词，代词是可以做宾语的，副词通常是和动词搭配的，
比如第一句 Study where, visited what? 前者缺的是状语，所以用关系副词，后者缺的是宾语所用有关系代词。因为副词是不能做宾语的。同样代词也不能承担副词的角色，去做状语。
因为在从句里充当的成分不一样1、The school where I study is very beautiful.The school which/that I visited yesterday is beautiful.第一句 study in the scool 所以是地点状语 用关系副词第二句 visit the sch...
先看第一组句子先把where去掉，肯定不能说i study the school 。 但是在下一句把引导词去掉可以说i visited the school。 综上所述，去掉引导此后，动词之后不可以直接加主语的用where、when、why：可以直接加的用what、that。后两道题用同样的方法即可解答。学英语不能着急，认真听老师讲课
