文字稿

Hi! I’m Tom. And today I’m going to show you how to use tag questions.

We use tag questions to ask for confirmation.

For example: It’s a melon, isn’t it?

Isn’t it has a similar meaning to ‘do you agree’.

When the statement is positive, we make a negative question. And, when the statement is negative, we make a positive question.

It isn’t a banana, is it?

We can use other auxiliary verbs with tag questions. And these show a change in tense and meaning.

For example: You won’t eat my melon, will you?

When there is no auxiliary verb, we make a question using ‘do’.

Elly, you really like melons, don’t you?

She really does!

用法总结

1 反意疑问句的基本结构是：陈述部分＋疑问部分。疑问部分可用系动词 “be” 以及 “can”、“should”、“will” 等助动词，或动词 “do”，这些动词根据陈述部分的时态和含义变化。

It’s a melon, isn’t it?

We should go to work tomorrow, shouldn’t we?

You really like melons, don’t you?

2 反意疑问句通常用来向他人求证一件事情，其疑问部分可以理解为 “是这样吗” 或 “你同意吗”。

It’s cold, isn’t it? 

He can’t swim, can he?

3 通常情况下，如果反意疑问句的前半句为否定式，疑问部分则应为肯定式。

It isn’t a banana, is it?

You won’t eat my melon, will you?

She doesn’t like melons, does she?
