In today's lesson, you'll learn how to express yourself when you don't know something in English.

今天我們要來學習如何用英文表達「我不知道」。

This is actually such an easy method that I think by the end of this lesson, you'll already start using it.

不用擔心，真的很簡單。看完影片後，就會使用了！

So, let's have a look at the board and see how it works.

一起來看看白板上的字。

You start by using the phrase: "I don't know", and you connect it to one of these words or expressions.

首先，用「I don't know」開頭，然後加上以下單字詞組。

For example: "I don't know who is going to the party." "I don't know what to do." "I don't know what to say." "I don't know what to cook."

例如，我不知道誰會去舞會；我不知道該怎麼辦；我不知道要說什麼；我不知道要煮什麼。

Right? "I don't know when he's arriving." "I don't know where my glasses are." "I don't know why she left her job." "I don't know how to reach him."

我不知道他何時會來；我不知道我的眼鏡去哪了；我不知道她為什麼辭職；我不知道怎麼連絡他。

"I don't know how to drive." "I don't know how to swim." And so on.

我不會開車；我不會游泳，等等。

"I don't know how much it costs." "I don't know how many people were at the concert."

我不知道這要多少錢；我不知道多少人去了那場演唱會。

"I don't know how often he goes to the club." "I don't know whether Jane has arrived."

我不知道他多久去一次夜店；我不知道 Jane 到了沒。

"Whether", spelt like this: "whether" means "if". All right? It's another word for "if"

Whether 和 if 的意思一樣，都是「是否」的意思。

"I don't know whether Jane has arrived yet." "I don't know if I locked the door." "I don't know if I locked the door."

我不知道 Jane 是否到了；我不知道門是否有鎖。

So, you can see that by using that one expression "I don't know" with any of these words, you can express a range of information.

只要「I don't know」和下列這些字詞並用，就能傳達許多意思。

Now, a couple of points to keep in mind.

還有幾點要注意。

You can use this expression and combine it with present, past, or future tense.

「I don't know...」在現在、過去和未來式都可以使用。

What do I mean? Well, you could say, "I don't know who usually goes to his parties." That's present tense.

什麼意思呢？比如，你可以說：「我不知道誰通常會去他的派對」也就是現在式。

"I don't know who went to his party." Past tense.

「我不知道誰去過他的派對」這就會是過去式。

Or "I don't know who is going to his party." Future tense. Right?

或是未來式的「我不知道誰會去他的派對。」懂嗎？

So you can do this with all of these words; you can use it in the present, in the past, or in the future.

這些字和詞組都可以用在過去、現在、或未來式。

And one last, very important point to keep in mind, regarding the word "know", regarding the verb "know".

最後，非常非常重要的一點，注意動詞 know 的用法。

The verb "know" is a stative verb. A stative verb means that you cannot use it in the continuous form.

Know 是狀態動詞，不能用在進行式中。

You can only use it in the simple form, like this.

只能用在簡單式，像白板上寫的這樣。

So you can only say "I don't know", not "I am not knowing."

所以，你可以說「I don't know」，但不能說「I'm not knowing.」

Many people in different parts of the world use... tend to use continuous forms for everything in English,

很多外語人士人講英文時，習慣什麼都用進行式，

but you have to be really careful not to use the continuous forms with stative verbs.

但使用「狀態動詞」時，一定要注意不能用進行式。

"Know" is a very common stative verb; there are many others like it.

除了 know 這個常見的狀態動詞外，其他狀態動詞也一樣。

So other than that, you're fine.

除此之外，你們都知道如何使用。

You couldn't say... sorry, you could also say: "I don't know" or "I didn't know". All right?

你也可以用過去式 I didn't know。

So you could use this part, but remember not to change the verb "know".

可以改變 don't 的部分，但 know 本身不能任意改變。
