I wonder know what will happen next.宾语从句不是要用陈述语句吗,为什么是what w We observe what will happen?应该是宾语从句,可是宾语从句,不是要求后面要用陈述句语序吗? 请问I don't know what to do next.中的what to do next是宾语从句吗?为什么? I don't know what is the time为什么这里的宾语从句不用陈述语序? 英语从句语序I do not know when will i be free 这是宾语从句吧 从句不是用陈述语序么?应 i wonder what is the matter 为什么what 是主语不用倒装而其他宾语从句一般要倒装 英语中：宾语从句为什么要用陈述语句:Mary wants to know where Bob lives. i don't know what happen ,后面的名词性从句what是代主语还是宾语. can you tell me what the matter is with you为什么不对?宾语从句不是要用陈述语 what will happen next? 请问：宾语从句请举个宾语从句的例子,连接词要用what,how.书上说宾语从句部分要用陈述语气,如Do you know 关于宾语从句不是说宾语从句要用陈述句语气吗,为什么当宾语从句的引导词是who,which,what,when,where
