I don't know 后面跟的宾语从句是用现在还是用过去时态?比如 I don't know what you said /say.那个准确宾语从句 主句和从句的时态 可以 前后不一致吗？

I don't know 后面跟的宾语从句是用现在还是用过去时态?比如 I don't know what you said /say.那个准确宾语从句 主句和从句的时态 可以 前后不一致吗？ i don't know what happen ,后面的名词性从句what是代主语还是宾语. 正确的句子是I don't know what I should say还是I don't know what should I say.求解释在宾语从句里什么时候可以直接在what等代词后面跟疑问词,比如can do will等等；什么时候疑问词要放在主语后面? excue me I don't know I am blocking your way 为什么不用宾语从句?excue me I don't know that I am blocking your way 难道I don't know后面可以直接接句子? i don't know which one to choosewhich one 是KNOW的宾语还是KNOWN后面宾语从句的主语?I didn't know which one to choose .主语 谓语 不定式做宾语 不定式做宾语 ,怎么which one是 choose 的宾语 宾语从句的否定形式i don't think i know you能不能写成i think i don't know you如果不能为什么? I don't know what to do (改为含有宾语从句的复合句） whose 引导的宾语从句.这样：I don't know whose watch it is . 介词后面要跟宾语,那么i don't have a practicce English with.为什么不要类? I don't know how we should solve the problem.这how后面的是宾语从句但这个I don't know how to solve the problem.这里的how ...后面的是什么成分呢?how to do sth 这应该不是宾语从句吧?都没有主语啊…… what is the matter with you主语是what还是the matter?I don't know后面该怎么用?I don't know 后面是用what is the matter 还是 what the matter is做宾语从句 i don't know放句首i don't know 放句首时后面的句子用陈述语气?如 i dont know what you're talking about I don't know what is the time为什么这里的宾语从句不用陈述语序?按理来说应该是I don't know what the time is The small children don't know what is in their stockings为什么说后面的宾语从句为陈述语句? 反意疑问句中如果有宾语从句,请问后面的疑问部分的人称是跟主语的人称还是宾语的人称比如：I don't think she can pass the exam,_________? 宾语从句I don't know what is his name 还是 I don't know what his name is? ( )I really don't know _____A.what should I do B.what to do C.what do I( )I really don't know _____A.what should I do B.what to do C.what do I我在百度搜到答案是B的原因是不定式作宾语 一种是及物动词后直接跟带to的不定 I don't know.
