Oftenworkingatnight为什么用working而不用work

这就不是正当语法句子, 必須改正才能再说。

举例 :

1.   We are often working at night.         [are working 現在进行时态]

2.   We often work at night.                     [work 现在时态]

3.   Working is my favourite at night.     [Working 动名词 V-ing]

用 work 或又用或不用 working, 全都要看你想做何类文法及结构形式的句子而定。上面就是好例子了。
