what与that的区别在用法上的区别
一、引导词what与that在引导名词性从句的用法区别引导主语、宾语或表语从句时,what在从句中要充当句子成分；而that引导主语、宾语、表语和同位语从句时,不作任何成分,只起语法连接作用.试比较：
That George W. Bush won the presidency once again was what many people hadn't expected.乔治?布什再次赢得总统大选,这是很多人没有预料到的.
It is the same old story of not being grateful for what we have until we lose it.事情往往是这样,失去之物,方知珍惜.
二、引导词what与that在引导定语从句的用法区别首先,要记住在定语从句中,跟本不用what连接词.只有that和which.所以大家在做题中,如果是定语从句,就不要再考虑what了.That 在定语从句中,一般可以作从句的主语.宾语和表语.例如：
1、 Do you still remember the chicken farm ____ we visited three months ago?
where B when C that D what
「分析」C 定语从句连词,that做从句visit的宾语.没有what连词.
2、He is not the naughty boy that he used to be.他不再是从前那个调皮的男孩了.
