needn't和don't Need 还有You'd Better的问题you'd better .hadn't you you'd better = you had better 为什么不能用didn't you I'd like = I would like那反义疑问句用什么?She _____ worry about the physics contestA.needn't toB.needsC.dosen't needD.doesn't need to是不是选D吖?needn't to 和dosen't need to有什么区别?什么情态动词的不要讲.我听不懂...-0-如果我要说 {我不用去买牛奶} 怎么讲.

问题1：had 在这里作情态动词，所以hadn't。
问题2：陈述部分有You'd like to +v. 疑问部分用wouldn't +主语。而且，一般没有对自己说的话问反义疑问的，主语一般不为 I。
问题3：选D，此外，A项去掉to 也正确。
问题4：从意思上二者基本相同，need作情态动词多用否定疑问句中。needn't to 是一种错误说法。奉劝最好将情态动词掌握，这是很重要的语法知识。呵呵~~
问题5：You needn't go to buy some milk.=you don't need to buy some milk.
