Bad is often used as an adverb in sentences such asThe house was shaken up pretty bad orWe need water bad. This usage is common in informal speechbut is widely regarded as unacceptable in formal writing.In an earlier survey,the sentenceHis tooth ached so bad he could not sleep was unacceptable to 92 percent of the Usage Panel. · The use ofbadly with want, once considered incorrect,is now entirely acceptable:
Bad 在句子中常用作副词， 如这座房子摇晃得很厉害， 或是我们非常需要水。 在非正式演讲中这一用法很普遍，但在正式书面语中广泛地被认为不能接受。在早期的调查中，句子他牙疼得厉害以致睡不着觉。 对于92%的用法小组成员来说是不能接受的。badly 和 want 连用的用法， 曾经被认为是不正确的，现在则完全被接受：
例句：
We wanted badly to be at the wedding. ·
我们非常想参加婚礼。 ·

The adverbbadly is often used as the complement of verbs such as feel, as inI felt badly about the whole affair, where the choice ofbadly as opposed to bad may convey an implication that the distress is emotional, rather than physical.Although the origin of this usage is a matter of dispute,the usage is now widespread and is supported by analogy to the use of other adverbs withfeel (as inWe feel strongly about this issue ). In an earlier survey,a majority of the Usage Panel accepted this use ofbadly in speech, thoughbad is less likely to occasion objections.Badly is also used in some regions to mean .unwell,. as inHe was looking badly after the accident (comparepoorly, which is also used in this way). In an earlier survey, however, the usage was found unacceptable in formal writing by 75 percent of the Usage Panel.
副词badly 常用作动词的补充，如 feel， 在句子我对整个事件感觉很糟 中， 选择badly 作为与 bad 的对立， 可能传达暗示这一压制的感觉是感情上的而不是身体上的。尽管对这一用法的起源有过争议，但现在已很普遍并被其他带动词feel 的类比词所支持， （如我们对这观点的感受很强烈 ）。 在早期调查中，用法小组大多数接受在口语中使用badly ， 尽管bad 相对不会引起异议。 Badly 也被有些地区用来表示.不好.，如在他在事故后看上去很糟 （和poorly 比较，也是同样用法）。 但在早期讨论中，75的用法专门小组成员不接受在正式书面语中使用这种形式
