以下为英英的解释
【not until】used to emphasize that something does not happen before a certain point in time or before something else has happened: 'Can I go out and play now?' 'Not until you've done your homework.' It was not until 1972 that the war finally came to an end. Don't give a business gift until you reveive one. 中文翻译:不要给商业礼物,直到你收为一个为止! 在选项中,只有unil具有否定的味道,其他的都没有!故答案选a! x1 |
