很高兴回答
需要,有如下两种情况
1(用于否定句后,引出另一否定句以补充前句) 也不
Cooking up a quick dish doesn't mean you have to sacrifice flavour.Nor does fast food have to be junk food.
做一道快餐并不意味着你就得牺牲味道.快餐也不见得非得是垃圾食品.
2(用于否定句后,以表示此否定也适用于自己、他人或别的事情) 也不
例：
"None of us has any idea how long we're going to be here."—"Nor do I."
“我们当中没人知道我们将要在这儿呆多久.”—“我也不知道.”
例：
"If my husband has no future," she said,"then nor do my children."
“要是我丈夫没有前途,”她说道,“那么我的孩子们也没有.”
