VOA一分鐘英語：反意疑問句 用法小結(jié)

英語中的反意疑問句通常用來向他人求證一件事情。這類句子的基本結(jié)構(gòu)是：陳述部分＋疑問部分。在把肯定式或否定式的陳述部分變成反意疑問句的時候，需要注意哪些結(jié)構(gòu)和時態(tài)上的變化？
 
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!
 
用法總結(jié)
1 反意疑問句的基本結(jié)構(gòu)是：陳述部分＋疑問部分。疑問部分可用系動詞 “be” 以及 “can”、“should”、“will” 等助動詞，或動詞 “do”，這些動詞根據(jù)陳述部分的時態(tài)和含義變化。
It’s a melon, isn’t it?
We should go to work tomorrow, shouldn’t we?
You really like melons, don’t you?
 
2 反意疑問句通常用來向他人求證一件事情，其疑問部分可以理解為 “是這樣嗎” 或 “你同意嗎”。
It’s cold, isn’t it? 
He can’t swim, can he?
 
3 通常情況下，如果反意疑問句的前半句為否定式，疑問部分則應為肯定式。
It isn’t a banana, is it?
You won’t eat my melon, will you?
She doesn’t like melons, does she?
