✔ 最佳答案
「1. The job needs to be done. 」是最正確,這是「need」的用法,請參看各大字典或 Yahoo Dictionary。

後記
有很多 verb 本身可以用作「主動」及「被動」的意思,我們不需要用它們的 passive voice,例如 break, crack, cook, float, sink, need。
He breaks the window.
The window breaks.
I am cooking the vegetables.
The vegetables are cooking.
I need to do the job.
The job needs to be done.
所以 2 及 3 是不需要的。

以下三句根本是不同意思,不能混為一談:
The job needs to be done. (某些人)需要做這工作
The job has to be done. (某些人)一定要做這工作
The job is to be done. (某些人)將會做這工作
