| 释义 | 〔margin〕To deposit margin for:给…付保证金：〔doubt〕That is also the usual choice when the truth of the clause following doubt is assumed, as in negative sentences and questions. ThusI never doubted for a minute that I would be rescued implies "I was certain that I would be rescued.” By the same token,Do you doubt that you will be paid? seems to pose a rhetorical question ("Surely you believe that you will be paid"), whereasDo you doubt whether you will be paid? may express a genuine request for information and might be followed bybecause if you do, you should make the client post a bond. In other cases, however, this distinction betweenwhether and that is not always observed, andthat is frequently used as a substitute for whether. If may also be used as a substitute forwhether but is more informal in tone. ·In informal speech the clause followingdoubt is sometimes introduced with but: I don't doubt but (or but what ) he will come. Reputable precedent exists for this construction,as in"I do not doubt but England is at present as polite a Nation as any in the World" (Richard Steele),but modern critics sometimes object to its use in formal writing.See Usage Note at but ,if 在否定句及疑问句中当doubt 后的从句所作陈述被认为是真时，用 that 。 所以我从不怀疑我会被救起 意思就是“我确信我会得救”。 同样你怀疑人家会赖帐吗？ 似乎就成了一个反问句（“你当然相信人家不会赖帐了”）， 而你怀疑人家是否付款吗？ 就表示一个真诚的询问， 可能接下来会说因为如果你怀疑的话，你就该让顾客付保证金 。 在其它情况下，whether 和 that 的区别并不很明显， 而且that 经常用来替代 whether。 If 也经常用来代替whether ， 但是语气不很正式。在非正式语气中doubt 后面的从句有时由 but引导：I don't doubt but （或 but what ) he will come。 这种结构有其先例且属规范用法，如“我不怀疑目前的英格兰象世界上其他国家一样是礼义之邦” （理查德·斯蒂尔），但现代评论家有时反对在正式文体中这样使用 参见 but,if |
