反意疑问句的否定式一定要用缩写吗
有网友问：反意疑问句的否定式是否一定要用缩写。根据英语语法，当反意疑问句的附加部分为否定式时，习惯上只用缩写形式，不能分开来写。如：
正：Peter helped you, didn’t he? 彼得帮了你的忙，是吗?
误：Peter helped you, do not he?
正：You love him very much, don’t you? 你很爱他，对不对？
误：You love him very much, do not you?
正：You’ve got my E-mail, haven’t you? 你接到了我的电子邮件了，对吧?
误：You’ve got my E-mail, have not you?
正：You locked the door, didn’t you? 你锁门了，不是吗?
误：You locked the door, did not you?
正：You can just picture the scene, can’t you? 你完全能想象出那个画面，对吗？
误：You can just picture the scene, can not you?
但是，如果将not置于主语之后是可以的，尽管这种用法非常正式且比较少见。如：
She knows you, does she not? 她认识你，不是吗?
Julia runs five miles a day to keep fit, does she not? 朱丽叶为了锻炼身体，每天跑5英里，不是吗?
