i really dont know what i could have done yesterday evening without your help为什么要用could have done ?should have done 行不行?

Whats the differences between I really dont understand andI dont really understand Literally wanna know :D cos i really dont wanna know you when you dont know where you found my icq什么意思 到底是 i really dont know 还是 i dont really know 这个副词到底放哪里?为什么 副词不是应该放在 行为动词前其它动词后面吗 为甚么是i really dont know i dont know f why?I dont know! i dont know her “i dont know chinese ” i dont really know if this is working out 翻译不要在线翻译的 “I dont know !”是什么意思啊? i dont want to know really?I dont care? 这个什么意思 I really dont know if is good or not for me this yers .sonething is out of my control! i dont know,image i don i dont know who am i I do,you know i really really I really dont like it.和 I dont really like it.这两句有什么区别? Dont+speak+English+I+dont+know+English甚么意思 英语翻译原话是这样的：soo..I dont know what to do,I just feel really sad I probably broke ur heart...ure really just the kind of girl I really really like,...hope we can just stay friends..dont know..maybe just friends is better or?有一
