i don't know what to do 和i don't know how to do i

i don't know what to do 和i don't know how to do i~

i don't know what to do 我不知道要做什么（我现在无所事事，没什么可以做的事情）
i don't know how to do 我不知道如何去做（我不知道做某件事的方法）

I don't know what to do中what to do是宾语从句吗

是的，这个句子是主谓宾结构，动词后面跟宾语，what to do做know的宾语。

我不知道做什么。

仅仅从what to do和how to do it来说，你们老师说的区别是对的!你后边的例子：he teaches me how to study.相当于study后边省略了某个名词如语文和英语。具体地说，how表示方式，学习的方式，what在what to do 中作宾语。所以do后边不再需要其他词。而how to do 中需要一个宾语“某物，某事”its或omething

其实如果不是必须掌握语法，可以不用那么深究。至于老师说的只是这种特殊形式，这也是常考点。记住就可以了。

he teaches me how to study这句话中的study 就是名词

不是
