  • Hi, my name is Rebecca from In today's lesson, you will learn how to express


  • yourself when you don't know something in English. This is actually such an easy method


  • that I think by the end of this lesson, you'll already start using it. So let's have a look


  • at the board and see how it works. You start by using the phrase: "I don't know",

    我們一起來看白板上的字。首先,先用「I don't know...」(我不知道...) 開頭

  • and you connect it to one of these words or expressions. 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." 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.",


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


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


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


  • spelt like this: "whether" means "if". All right? It's another word for "if". "I don't

    "Whether" 和 "if" 的意思一樣,它們都是「是否」的意思

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


  • if I locked the door." 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.

    「I don't know...」只要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. You can use this expression and combine it with

    再來,還有幾點要注意,「I don't know...」可以和各種時態搭配使用

  • present, past, or future tense. What do I mean? Well, you could say: "I don't know who


  • usually goes to his parties." That's present tense. "I don't know who went to his party."

    我不知道通常都是哪些人去他的派對 —「現在式」;我不知道誰去過他的派對 —「過去式」

  • Past tense. Or: "I don't know who is going to his party." Future tense. Right? So you


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


  • And one last, very important point to keep


  • in mind regarding the word "know", regarding the verb "know". The verb "know" is a stative


  • verb. A stative verb means that you cannot use it in the continuous form. You can only


  • use it in the simple form, like this. So you can only say: "I don't know", not: "I am not

    只能用「簡單式」,像白板上寫的這樣。所以你可以說「I don't know...」,但不能說「I'm not knowing...」

  • knowing." Many people in different parts of the world use, tend to use continuous forms


  • for everything in English, but you have to be really careful not to use the continuous


  • forms with stative verbs. "Know" is a very common stative verb; there are many others


  • like it. So other than that, you're fine. You couldn't say - sorry -, you could also


  • say: "I don't know" or "I didn't know". All right? So you could use this part, but remember

    另外,除了說「I don't know」,你也可以用過去式「I didn't know」。聽清楚囉!可以改變的是「don't 」的部分

  • not to change the verb "know". If you'd like to practice this, please go


  • to our website at There you'll find a quiz on this subject. And if you found


  • this lesson useful, please subscribe to my channel on YouTube. Good luck with your English.


  • Bye for now.
