個example 係 from yahoo,我費時自已打:

Need NOT 用法分別:
needn't have v-ed 表示過去做了某事，但没有做的必要， 意為“本來唔晒做”。例如：
You needn't have waken me up; I don't have to go to work today.
你本來唔洗叫醒我, 我今日唔需要返工!
We need not have worried about the math exam. It
was a piece of cake.
我們本不必擔心數學考試,實際上很容易。
we don't have to worry about the math exam. It
is a piece of cake
我們不需要擔心數學考試,因數學是很容易
兩句的意思係唔同
