请问:we need to persist in everything what we have made up our minds to do.what 在这里是什么从句?what 改为that

是主语从句，作宾语从句的主语，不可以换成that，that引导的主语从句不缺成份，而what则缺。

大哥，我突然想起来你这个句子是错误的,我给你三种表达方式
1.we need to persist in what we have made up our minds to do
2.we need to persist in everything that we have made up our minds to do
3.we need to persist in everything we have made up our minds to do
这才是正解OK？

宾语从句,we need to persist in everything 做what we have made up our minds to do的从句.what 改为that是可以的
