解釋

Camile: Hi Daniel. Do you know how to use the word ‘if’ correctly in English conversations?

凱密拉：嗨，丹尼爾。你知道在英語的對話中怎樣正確使用”if”嗎?

Daniel: I do know how to use ‘if’ in some sentences. But sometimes it’s very confusing and I just can’t figure out when and where to use it.

丹尼爾：一般情況下我知道怎樣使用“if”.但是有時候我對在什么時候和怎么用感到很困惑。

Camile: I know some situations when we can use it.

凱密拉：我知道在一些情況下我們可以用它。

Daniel : Okay, like what?

丹尼爾：比如說?

Camile: Here’s an example: If you don’t drink water, you’ll die.

凱密拉：舉個例子來說：如果你不喝水的話，你會死的。

Daniel : Okay, so I can say that if you stand in the rain, you’ll get wet, which is true and happens to me a lot.

丹尼爾：好，我也可以說，如果你下雨的時候站在外面會感冒的，這種事情在我身上經(jīng)常發(fā)生。

Camile: Yeah, that’s right. Let’s take another example, where ‘if’ can be used to talk about the possibility of something happening in the future. You tell me this time.

凱密拉：對，是這樣的。我們再舉一個例子，”if”在表示未來發(fā)生的事情的可能性的時候可以用。你舉個例子吧。

Daniel: Let me see… Okay, I know: if I were a millionaire, I would buy an airplane.

丹尼爾：我想想……有了，如果我是一個百萬富翁，我會買一架飛機。

Camile: Yep, that’s correct. Great job!

凱密拉：對，這樣是對的，做得好!

Daniel: I think ‘if’ is also used to join two conditions together in which the second condition depends on the first one.

丹尼爾：我認為”if”可以在將兩種條件聯(lián)系在一起時用，并且后一種情況取決于第一種情況。

Camile: That’s right, Daniel. For example, I won’t be hungry anymore if I eat a pizza.

凱密拉：對，比如：如果我吃披薩的話就不會餓。

Daniel: Yes, in your example, there are two situations. Eating a pizza, and being hungry. If you eat a pizza, then you won’t be hungry.

丹尼爾：對，在你的句子中有兩種情況。吃披薩和感覺到餓。如果你吃披薩那你就不會餓。

Camile: Okay, now let’s listen to some conversations.

凱密拉：好，下面我們來聽一聽對話吧。
