这里的,not unless

这里的,not unless not unless和unless的区别 an order ( ) be put,unless a contract signed.这里用的是should not 还是shall not,为什么? 一个英语句子的翻译6-28it is not real work unless you would rather be doing something else.1、先翻译下句子.2、这里it is not unless 是不是等于it is not until not unless啥意思 not unless 意思! 新概念第三册英第一课问题..and experts confirmed that a puma will not attack a human being unless it is cornered.这里的being看不懂为什么用在这里?起什么作用? not if与unless 区别 puma will not attack a human being unless it is conered 其中being在这里是什么意思,为什么用being 词组翻译 premium transportation什么意思如题.提供一下语境：not use premium transportation unless specifically authorized by Buyer。为什么我觉得这里是指高价运输的意思？恳请高人回答。是拼错了，囧出处是 Not unless i have an amazing stroke of luck!It's very unlikely that anything like that willhappen 特别是前面的Not unless I won't finish the work unless you help me .这里的unless you help me 可以替换成until you help me么 I won't go there unless I'm invited.这里的unless I'm invited可以像if一样移到开头吗? not until 和unless的区别 我怎么觉得意思都差不多呢 You are not a hero unless you climb on the Great wall 的中文 啊啊谁能发一些关于if...not 和unless的练习（初中）,要有讲解, if…not与unless在这里都能用吗?I'll be surprised if he doesn't have an accident.I'll be surprised unless he have an accident.这两句对吗?为什么? if...not和unless怎么转换
