附加疑问句的主语

附加疑问句的主语总是使用代词。这个代词要与陈述句的主语保持一致。例如：

1. He likes his job, doesn't he? 他喜欢他的工作,是不是?

2. Joan recognized you, didn't she? 琼认出了你,是不是?

3. It's colder today, isn't it? 今天比较冷,是不是?

但是,下面几点应特别注意:

一、陈述句如果是 there be 句型，则附加疑问句要用 there 充当主语，而不用 it 或 they 来与存在句中的主语保持一致（参见 tag questions $^{18}$ ）：

1. There is a pen on the desk, isn't there? 书桌上有支钢笔,是不是?

2. There were lots of people over there, weren't there? 那边有许多人,是不是?

3. There's nothing wrong, is there? 没有出什么事,是吧?

二、陈述句的主语如果是 everyone (everybody), someone (somebody), anyone (anybody), no one, nobody, 则在附加疑问句中通常使用 they, 尤其是在口语中。但是, 使用 he 也是正确的 (见 tag questions $^{11}$ ):

1. Somebody borrowed my coat yesterday, didn't they? 昨天有人借走了我的大衣，是不是？

2. No one was injured in the car accident, were they? 这次车祸没有人受伤,是不是?

3. Someone died here yesterday, didn't they? 昨天这里死了一个人,是不是?

但在正式语体中也可以见到用he的实例：

Everyone knows his job, doesn't he? 每个人都了解自己的工作,是不是?

三、陈述句的主语如果是 this, that, these, those, 则附加疑问句中的主语要分别用 it 或 they:

1. That is your book, isn't it? 那是你的书, 是吗?

2. Those are nice, aren't they? 那些很好,是不是? 四、附加疑问句通常要重复复合句中主句的主语,但主句中如果含有 I think/suppose/expect/believe/imagine/fancy 这样的主谓结构,则附加疑问句应重复 that 从句中的主语:

3. I suppose you are not serious, are you? 我认为你不是认真的,是不是?

4. I expect you will have a good time there, won't you? 我预料你在那里会过得很愉快，是不是？

5. I don't believe he has finished, has he? 我认为他没有干完,是不是? 五、否定转移句的附加疑问句,其主语应重复 that 从句的主语,见 tag questions $^{9}$ 。

I don't think you can do these exercises alone, can you? 我认为你不能独自做这些练习，对吧？

六、在 Let's 与 Let us (me) 句后的附加疑问句的主语是不同的(参见 let's... shall we?)：

1. Let's go for a walk, shall we? 我们去散步吧,好吗?

2. Let us go home, will you? 让我们回家吧,行吗?

3. Now then, let me have a look at that project, will you? 现在，让我看看那份计划，好吗？

七、陈述句的主语如果是 one，则附加疑问句的主语应当用 one（英国英语）或 he（美国英语）：

One can't be too careful, can one? 做事越细心越好,是不是?

八、祈使句的主语为第三人称时，附加疑问句的主语既可用 you，也可用 they:

Somebody open this door, will you? /will they? 谁来开开门,好吗?
