Language points
反义疑问句结构：陈述句+简短问句。
（简短问句常译为“是不是？/不是吗？/是吧？/对吗？”等。）
一、反意疑问句
1. 反意疑问句遵循“前肯后否，前否后肯”的
原则，即陈述部分为肯定时，疑问部分为否
定；陈述部分为否定时，疑问部分为肯定。
前肯后否
他是一名司机，不是吗？
He is a driver, isn’t he?
2. 反意疑问句的回答根据事实上的“是”或
“否”回答。
Yes 后面接的一定是肯定句，
No后面一定接否定句。
翻译要根据当时的语境。
You have been to a space museum, haven't you?
Yes, I have.
You have been to a zoo, haven't you?
No, I haven't.
1.陈述部分有few, little, never, no, nobody,
nothing, hardly, seldom等否定含义的词时，
附加疑问句用肯定形式。
这个男孩几乎不会游泳，是吗？
The boy can hardly swim, can he?
二、常考的特殊句型
2. 陈述部分为 I am…时，附加疑问句用 “aren’t
I?”；当陈述部分以 I wish 开头时，疑问部分
常用 “may I?”
我和你妹妹一样高，不是吗？
I am as tall as your sister, aren’t I?
3.主句含有 I think/ suppose/ believe/ guess/ expect,
变反意疑问句时，注意否定转移。
我认为他不回来，对吗？
I don’t think he will come, will he?
