“I don't what to do.”中的what to do充当什么成分,是宾语从句吗?

“I don't what to do.”中的what to do充当什么成分,是宾语从句吗?
是I don't know what to do
作宾语,不是宾语从句,what to do就是个带疑问词的不定式短语,
不是句子,主语谓语都没有.
不定式作宾语有两种情况：一是及物动词后直接跟带to的不定式,二是“动词+疑问词 +带to的不定式”.
⑴“动词+带to的不定式”结构：常见的以不定式作宾语的动词有afford,agree,believe,decide,fail,hope,want,plan,choose,prepare,forget,remember,begin/start,learn,promise,refuse,wish等.如：
I can’t afford to buy a house.
⑵“动词+疑问代（副）词+不定式”结构：常见的这类动词有advise,decide,forget,know,learn,remember,see,tell,think,teach,wonder,understand,guess,explain等.这类疑问代（副）词what,when,which,where,how,whether等（不包含why）.如：
She does not know how to go there.
He will tell you when to start.

是宾语从句

这个句子都是错误的
要不就是i don't know what to do

i don't know what to do I understand,but,I don't know what to do? 翻译I don't know what to say or do. i don't know to do what 对吗 i don't know ()to do.填what还是how I really don't know____nexta.how to do b.what to doc.what to do it I don’t know what to do.I don’t know how to do.（ × ）第二句 how 怎么错了?I don’t know what to do.(正确) I don’t know how to do.（ × ）翻译 what do you like to do,just to do,I don't mind. I don't know what to do 能否说成 I don't know what to be done. i dont know what to do (next) 和i dont know how to do (next)的区别为什么I don't know what to do成立而I don't know how to do不成立 please don't just do what i tell you ,do what needs to be done! I really don't know_____.A.what should I do B.what to do C.what does D.what doing I don't know___.A.what to do it B.what do C.have to do it D.how do I don't know what to say or do求同意句I don't know what should. Don't you do not understand what i want You still don't understand what i want to 什么意 What to do用法I really don't know____about it.A.what to do B.how to do I do not know what to do.同义句子I don't know_______ ______ _____ _____.
