这类词语有hardly, scarcely, rarely, seldom, never, few,little, less, at no time, by no means, in no case, under no circumstance, in no way,on no account, on no consideration, no longer, not only等。
eg. He never smokes. 他从来不抽烟。
Never does he smoke. eg. Not only did the customer complain about the food, he also refused to pay for it. 这位顾客不仅仅 抱怨食物不好，还拒绝付费。

eg. Only with you can I feel happy. eg. 只有当你来了这，我们才可以开始会议。

eg. The moon was so bright that the flowers bright as by day. 皓月当空，花朵就像白天那样的鲜艳。
