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

凯密拉：嗨，丹尼尔。你知道在英语的对话中怎样正确使用”if”吗?

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.

丹尼尔：一般情况下我知道怎样使用“if”.但是有时候我对在什么时候和怎么用感到很困惑。

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

凯密拉：我知道在一些情况下我们可以用它。

Daniel : Okay, like what?

丹尼尔：比如说?

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

凯密拉：举个例子来说：如果你不喝水的话，你会死的。

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.

丹尼尔：好，我也可以说，如果你下雨的时候站在外面会感冒的，这种事情在我身上经常发生。

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.

凯密拉：对，是这样的。我们再举一个例子，”if”在表示未来发生的事情的可能性的时候可以用。你举个例子吧。

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

丹尼尔：我想想……有了，如果我是一个百万富翁，我会买一架飞机。

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

凯密拉：对，这样是对的，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.

丹尼尔：我认为”if”可以在将两种条件联系在一起时用，并且后一种情况取决于第一种情况。

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

凯密拉：对，比如：如果我吃披萨的话就不会饿。

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.

丹尼尔：对，在你的句子中有两种情况。吃披萨和感觉到饿。如果你吃披萨那你就不会饿。
