      不是。

      need to do(“需要;需要做”)的被動語態是:be needed to do。例如:

      Some form of encryption is needed (by them) to protect confidentiality

      and integrity of data.被動:

      They need some form of encryption to protect confidentiality and

      integrity of data.

      需要用某種形式的加密技術保護資料的機密性和完整性。

      Only a small buffer is needed (by us) to read or write data. 被動:

      =We need only a small buffer to read or write data.

      它只需要使用一個很小的緩衝區來讀寫資料。

     need to be done當表示什麼事情需要被做的時候=need doing

      例如:The machine needs repairing.=The machine needs to be repaired.

      機器需要被修。
