附加疑问句 (Tag Question)
P109
特点：“前肯后否”或“前否后肯”
特殊情况
不同时态/句式的附加问句构成
1. 含be动词（am/is/are/was/were）
She is from the US, isn`t she
They weren`t late yesterday, were they
特殊：I am a teacher, aren`t I （am的否定附加问句用aren`t，不用amn`t）
2. 含实义动词（一般现在/过去时）
一般现在时：借助助动词do/does（主语为三单用does）
He plays the piano well, doesn`t he
They often go hiking on weekends, don`t they
一般过去时：借助助动词did
She visited her grandparents last week, didn`t she
We didn`t watch the movie, did we
3. 含情态动词（can/could/will/would/should/may/must）
He can speak French, can`t he
They should finish the task today, shouldn`t they
特殊：must表“必须”时，附加问句用needn`t；表“推测”（一定）时，按陈述句谓语动词时态判断：
You must finish your homework first, needn`t you （必须）
He must be at home now（=He is at home now）, isn`t he （推测现在）
They must have arrived yesterday（=They arrived yesterday）, didn`t they （推测过去）
陈述句的主语是名词时，附加问句的主语用相应的人称代词来代替
例：Beijing is a beautiful city, isn`t it
特殊结构（高频易错点）
1. 陈述部分为否定转移句型（think/believe/suppose/expect等动词+宾语从句）
① 附加问句的肯定/否定根据从句判断，主语与从句一致（主句主语为第一人称I/we）；
I don’t think he will come, will he （从句否定，附加问句肯定）
We believe she can finish it, can’t she （从句肯定，附加问句否定）
② 主句主语为二、三人称时，附加问句根据主句判断。
He doesn’t think she is right, does he （主句否定，附加问句肯定）
2. 陈述部分为祈使句
① 肯定祈使句：用“will you ”或“won`t you ”（表委婉请求）
Open the window, will you
Please pass me the book, won`t you
② 否定祈使句：只用“will you ”
Don`t talk in class, will you
特殊：
Let`s...（包含说话人）→ 附加问句用“shall we ”；
Let us/me...（不包含说话人）→ 用“will you ”
Let`s go for a walk, shall we
Let us help you, will you
3. 陈述部分含不定代词
① 陈述部分主语为指人的不定代词（somebody/anybody/everybody/nobody）：附加问句主语用they或he；
Everybody is here, aren’t they （=isn’t he ）
② 陈述部分主语为指物的不定代词（something/anything/everything/nothing）：附加问句主语用it。
Nothing is difficult if you try, is it
4. 陈述部分含指示代词
① 陈述部分主语为指示代词（this/that）：附加问句主语用it；
That sounds interesting, doesn`t it
② 陈述部分主语为指示代词（these/those）：附加问句主语用they。
Those are apples, aren`t they
5. 陈述部分为存现句（附加问句仍用there）
There was a hospital here, wasn`t there
6. 陈述部分含have to（附加问句通常用do的相应形式）
You had to finish the task, didn`t you
7. 陈述部分含否定词（never/seldom/hardly/scarcely/few/little/no/none等）：陈述句视为否定，附加问句用肯定
He seldom goes out alone, does he
There are few books on the desk, are there
注意：若陈述部分含带否定意义词缀的词，附加问句仍用否定。
It is unfair, isn`t it
易错点纠正
1. 错误：She likes singing, isn’t she
→ 正确：doesn’t she （实义动词需借助助动词）
2. 错误：I am your friend, amn’t I
→ 正确：aren’t I （am的否定附加问句固定用aren’t）
3. 错误：He must study hard, mustn’t he
→ 正确：needn’t he （must表“必须”时，附加问句用needn’t）
4. 错误：Nobody came late, didn’t they
→ 正确：did they （nobody表否定，前否后肯）
“前肯后否”型（正常翻译）
问：……，不是吗？/难道不是吗？
答：Yes→是 / No→不
例：He is a student, isn`t he 他是学生，不是吗？
——Yes, he is. 是的，他是。/ No, he isn`t. 不，他不是。
“前否后肯”型（回答反着翻译）
问：……， 是吗？
答：Yes→不 / No→是
例：He isn`t a student, is he 他不是学生，是吗？
——Yes, he is. 不，他是。/ No, he isn`t. 是，他不是。

翻译

2. These words aren`t too difficult to remember, are they ——Yes, they are.
我们下周会学习新的语法点，不是吗？——是的，我们会。
这些单词不难记，对吧？——不，它们很难记。
