that还是what(人教版教材九年级英语108页)

人教版教材九年级英语108页:

What did you use to do that you don't do now？(that是否应该改为what？)

请各位老师指点。谢谢！

What did you use to do that you don't do now？

that引导定语从句修饰疑问代词what.

你以前常做而现在不做了的事情是什么？

这个句子的定语从句其实纯属多余。因为used to do sth本来就表示过去常做的事情（现在已经不做了）定语从句为画蛇添足，写这个句子的人本身对used to do的理解有问题。

这里可理解为that之前省略了一个those。按严格的语法来讲，是个病句。当然它只是口语化的表达，没有遵循严格的语法。

What did you use to do that you don't do now？

一个很正常的句子，如，

When I was a kid, I used to swim in the river, but now I don't.

What did you use to do that you don't do now？

这句that引导的定语从句.

说掉划线部分多余，等于是说标红的部分多余，不知道是什么逻辑？

再如，

What did you use to do that makes you cringe nowadays?

What did you use to do that you don't do anymore?

used to 只说过去的习惯，它并没有说现在的情况。

鉴于很有经验的老师对used to也有误解，我再把used to的释义复制粘贴一下：

if something used to happen, it happened regularly or all the time in the past, but does not happen now
