I don‘t think I am improving和I don‘t think I improve语法上都对吧?

I don’t think I don't think I think ,I don't I think the .I don’t think I don`t think I konw和I think I don`t konw 这两句有啥区别 i don't think i konw和 i think i don't know哪个对 i don't think so I don't think.句型 翻译,i don't think I don't think studen I don't think I am a student,（ ) ( ) 反义疑问句 ,I don't think who I am,but I don't know you what things?
