This is Everyday Grammar. I'm Kaveh.
欢迎收看《每日语法》栏目，我是卡维。
And I'm Lucija. Kaveh, I looked over our episode today and I think there's a mistake.
我是露西佳。卡维，我看了今天的节目，我认为有个错误。
What is it?
是什么？
Well, it says we're supposed to be talking about expletives, but I don't think that's appropriate.
它说我们应该讨论咒骂语，但我认为这并不合适。
No, Lucija, it's not expletives, as in offensive words, but expletives as in grammar.
露西佳，不是的，它不是骂人话里的咒骂，而是语法里的虚词。
Seriously? Yes! In grammar, expletives are words that have grammatical purpose but do not carry meaning.
真的吗？当然！在语法中，虚词是有语法用途但没有意义的词。
There is a good way to explain this subject,
解释这个问题有个好方法，
I just know it, but I don't think I know much about expletives.
我只是知道虚词，但对它了解不多。
Well, you actually just gave a good example!
你刚刚就举了个好例子！
You used what is called an "existential-there sentence".
你用了所谓的“There存在句”。
What is that?
那是什么？
Let me explain by using a shorter sentence:
我用一个短句来解释。
There are mice in the house.
房子里有老鼠。
"There"(an expletive) is the grammatical subject,
“There”（虚词）是语法主语，
"mice" is the logical subject, and "in the house" is an adverbial.
“mice”是逻辑主语，“in the house”是状语。
Ok, but why would I use an expletive if it has no meaning?
好吧，但是如果虚词没有意义的话，我为什么要用它呢?
Phrases such as "there is" or "there are" point to the existence of something.
“There is”“there is”等短语指向某物的存在。
They have meaning. But the individual word "there" (an expletive) doesn't have a meaning.
它们有意义，但是“there”（虚词）一词没有意思。
It is serving a grammatical purpose.
它是为语法目的服务的。
It helps writers and speakers control the rhythm of a sentence.
它帮助作者和说话者控制句子的节奏。
And that's Everyday Grammar.
以上就是今天的全部内容。
