the word "unless" correctly in English. Now, the word "unless" expresses a negative condition.

在英文中正確使用unless這個單字, 今日,我們使用unless這個單字表示一個否定的狀態

That means that unless one thing happens, something else cannot happen.

這表示除非一件事情發生了,不然其他的事是不會發生的

Let's look at some examples on the board, and I think you'll learn this very easily, okay? Let's get started.

我們來看一些白板上的例子,我想這樣你會非常容易學習,好嗎? 開始囉

Now, for example, let's take the first sentence: "You can't go to university if you don't finish high school."

現在,舉例來說,讓我們看第一句,你是不能唸大學的,假如你沒有完成高中學業的話

So the negative condition here is "if you don't finish high school", right?

所以這裡的否定狀態是"假如你沒有",完成高中學業,對吧?

So instead of saying "if you don't", you could say, "You can't go to university unless you

所以取代"if you don't"這個說法,你可以說,"你無法唸大學,除非你

finish high school." Okay? "You can't go to university if you don't finish high school"

完成高中學業",會了嗎?你不能唸大學,假如你沒有完成高中學業的話

or "You can't go to university unless you finish." So here, you see that we had to use

或"你不能唸大學,除非你完成....,"所以這裡,你看, 我們需要使用

the negative words, "if you don't". But when we use the word "unless", it does that automatically.

否定詞,"假如你沒有",但是當我們使用unless這個字時,它自動變成否定狀態了

Let's look at another example: "You can't enter the club if you don't have ID." "ID"

讓我們看看另一個例子,你不能進入俱樂部,假如你沒有身份證的話,"ID"

is short for "identification". "You can't enter the club unless you have ID. You can't

是身份證的英文縮寫,你無法進入俱樂部,除非你有身份證.你無法

enter the club unless you have ID." Next one: "You can't visit Italy if you don't

進入俱樂部,除非你有身份證. 下一題,你無法去義大利,假如你沒有

get a visa." So what do we do? We place this, and we can say, "You can't visit Italy unless you get a visa."

取得簽證的話, 所以我們要怎麼做, 我們將這句放在這裡,然後我們可以這樣說, 你無法去義大利,除非你取得簽證

"You can't borrow books if you don't have a library card." How would we change that

你無法借書,假如你沒有圖書館借書證的話,我們要如何換句話說?

using "unless"? "You can't borrow books unless you have a library card."

使用"unless"! 你無法借書,除非你有圖書館借書證

Last one: "You can't pass the TOEFL if you don't prepare." How would you change that

最後一題:"你無法通過托福考試,假如你沒有準備的話" 你會如何換句話說?

using "unless"? "You can't pass the TOEFL unless you prepare." All right?

使用"unless"?"你無法通過托福,除非你有準備", 都會了嗎?

Next, I'll give you an exercise so you can practice this a little bit better.

接下來,我會給你一個練習,如此一來,你可以把這個句型練習得更流暢,

Now, let's try a couple of examples with "unless". Let's say this is the situation: "John can't

現在,讓我們試試一些使用"unless"的例題,比如說,下列這個情況,John無法

go out unless he does a few things." So how would you say that? "John can't go out unless

出去玩,除非他做了某些事情,所以你會怎麼表達這些情況? "John無法出去玩,除非

he finishes his homework; unless he cleans his room; unless he takes a shower." Okay?

他完成他的家庭作業,除非他打掃完他的房間,除非他洗完澡," 了解了嗎?

Good. Let's see if you can do this one. You can

非常好,讓我們看看你是否會做這一題, 你可以

say it at home: "I can't improve my English unless I read more books; I write more often;

在家這麼說,"我無法增進我的英文能力,除非我看更多的書,我更常練習寫作

I watch more EngVid lessons." Okay? So you see how "unless" can be used in these

我看更多EngVid的課程" 沒問題嗎?所以你了解unless可以如何被使用在這些

examples. Try your best to write some sentences of your own, create a situation that, "Today,

例句中,試著盡力去寫一些你自己的句子,建立一些情境,"今天

I can't do this unless I do that." And each day, if you write a sentence like that with

我無法做這件事除非我完成那件事", 然後每一天,如果你寫一句這樣的例句,

what you need to do or what has to happen before something else can happen, you will

你必須完成什麼事或者哪一件事必須在某一件事之前發生,你會

learn how to use the word "unless". So if you'd like to do a quiz on this subject,
