你没有我那么快。------正确 你没比我那么快。------ 你没比我快。/你没比我快多少。

“你没有我那么快”是正却的，另一个则要说“你没比我快”或者“我那么快，你比不上我”

1，第二个句子的表达式不对的。可以说，你没比我快。或者你没比我快多少。 2，三个句子表达的意思不一样。 (1)你没我那么快, meaning "You are not as fast as I am" 言下之意，我很快，你追不上我。(The implication is: I am fast, and you can't catch up.) (2)你没比我快，meaning "You are not faster than me.". In certain context, it may mean: both of us are slow. (3)你没比我快多少，meaning "You are just a little bit faster than me.
