"不知道"翻译为什么一定是I don't know 而不能是Don't know

不知道翻译为什么一定是I don't know 而不能是Don't know I DON'T SEE WHY是不是我不知道为什么 “我不知道他是谁”用英语怎么说?是I don't know who is he.还是I don't know who he is.为什么? 为什么在英语中说“我不知道”是：I don't know而不是I no know I _____your father______come here next week.A.suppose;can't B.don't suppose;canC.don't suppose;can't D.suppose;should have答案上给的是B,但是我很疑问为什么不选C,同样也能翻译只是多了一个not?知道为什么的请速速回答 我不知道他为什么喜欢海豚：I don't know _______ _________ _________ _______. 我不知道他昨天为什么没去参加聚会.I don't know ________________ yesterday. 我没有时间为什么翻译为I don't have any time而不翻译为I don't have any times? don't you let my friend and i help you 句子成分分析是有关人称代词的 我不知道为什么这里用I Why don't you can say no?为什么你不可以说不?是这样翻译吧. 我不知道Jim在哪里I don't know_________ 英语翻译I am doing great so don't worry可是我不知道该怎样翻译比较好 我不知道是否要下下雨 翻译I don't know____ ____ ____it is going to rain 翻译I don't know ___ ___ tell him the news.(我不知道该如何告诉他这个消息.) 我真的不知道该怎么办的英文 I really don't know___ ___ ___ 是填what to do 还是how to do为什么 I'm afraid you can't sit here. Sorry,I ___know. A.don't B.didn't 老师说是A,我觉得是B为什么啊don't不是表示现在也不知道吗?不应该用以前不知道的didn't吗? 我不知道他是谁的英文翻译是i don't know who is he 还是i don't know who he is I don't know what is it 和 I don't know what it is RT,意思是我不知道这是什么
