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 contest
A.needn't to
B.needs
C.dosen't need
D.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.??

1.had这里不是过去式，而是had better do这一固定结构，所以是hadn't you

2.没听过也没必要这样反问自己把，一般只有问Would you like...?

3.选D啦，理由是needn't=doesn't need to

4.没有needn't to, 记住needn't=doesn't need to就OK啦

5.I needn't buy milk./I don't need to buy milk.(后者较常用）

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.
欧啦！，打字辛苦~~~~
