Question

英文对错判断
That is all what I want to talk about
语法上分析应该是 that is all that.才对,但经常见that is all what,到底是哪一个对?

Answer 1

楼主,第一个that可以暂时不看,只是起到一定的迷惑作用,可用“it”或“this”代替
最重要的是要记住
what=all that ,此处的what代替了先行词和引导词,即先行词+ that
例句：
All that should be done has already been done.（定语从句）
= what should be done has already been done.
意为应该做的已经做好了.
至于that is all what,个人认为是现在英语在中国人使用过程中的一种误用,我刚才查了一下,在一些博客的日志里有人会像这样写.遇到考察all,that ,what的题目时,一定要记住what=all that
