是的，但...

1. Need可做情态动词，这时你可以说：

    You needn't say it.

2. Need也可做行为动词，这时你可以说：

    You don't need to say it.

    或者 You do not need to say it.

3. 诗歌箴言里仿古，这时你可以说：

     You need not to say it.

     这从You don't need to say it 而来。比如把 The tears don't dry说成 Tears dry not。

     不过，need既可做情态动词也可作行文动词，既然用 You need not to say容易被看作用错了，我同意把它改成 You need not say...

或者You needn't say ...

或者 You don't need to say ...
