欢迎收看《每日语法》栏目，我是卡维 N;3^-K(G2kyM*_ 。
And I'm Lucija. Kaveh, I looked over our episode today and I think there's a mistake.
我是露西佳 Xj=TLpdQ1HQ[ 。卡维，我看了今天的节目，我认为有个错误 R7|rq7^rPSbMxD;7EaWP 。
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 ,86O]YAplKb#ZnAxggs 。
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 6X|e~!K%oBUI 。
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 c;SvzAnP3[PCb-OtqK! 。
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 tTy5fly&A78#Ok^( 。

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” L.sVcBI);M&Ii 。
What is that?
那是什么？
Let me explain by using a shorter sentence:
我用一个短句来解释 ;z^bOW_r_t26fwy&rHA 。
There are mice in the house.
房子里有老鼠 qeA25C%[ks8FC.Fk;.# 。
"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 FGZ,~KE&N2TsWd#y(OV; 。
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 vB,rY]J=(Whv+K 。
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 Iu4xjn=O;L#g 。
It is serving a grammatical purpose.
它是为语法目的服务的 P=fKCc6F2b!Om.j5 。
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 ~g%dcEMH+)&C 。
And that's Everyday Grammar.
