I dont know 是完整句子吗如题 还是 I dont know it 是完整句子 sorry?i dont know.ack a().把对话补充完整 i dont know f why?I dont know! i dont know her “i dont know chinese ” “I dont know !”是什么意思啊? i dont want to know i dont even know 还是 I even dont know? 那个是对的?或者那个更地道? 2句句子有分别吗?I dont know that she is pretty I dont t2句句子有分别吗?I dont know that she is prettyI dont think she is prettyThat怎样用? 这个句子对吗?我怎么觉得不完整.这个是一个句子中截下来的.是i dont know how difficult it is to find a right guy in the street.但是是不是也可以单独做一个句子呢? I dont know why he was late.这个句子里为什么用why不用that?我打错了　是Idont know the reason why he was late 这句英语该怎么写dont you know what kind of man i am?还是 dont you know what kind of man am 我认为是第一个句子正确 i dont know,image i don i dont know who am i I dont't know what do you 还是这根本就不成句子? i dont know who are those people这个句子对么?这个句子难道不是i dont know who those people are我认为在谓语动词know后面的从句应该由疑问语序变为陈述语序,我认为下面的句子是对的,可是书上的答案是 Dont+speak+English+I+dont+know+English甚么意思
