Zero conditional （零條件句)

上一期在【关于落在13日的迷信星期五】讨论了The First Conditional/第一条件句，今天我们继续来学习另一个条件句：

The Zero Conditional

The Zero Conditional is used when we talk about situations that are always true and as a consequence are about the past, present or future.

零条件句主要谈论一些永远是真的事实。

• If anything bad happens to me, I just blame it on coincidence
• When the sun goes down, it gets dark.*
• It lights up if you push that button.

记得，The present simple is used in both clauses. 这种情况，两个从句都用一般现在时。

* It is commonly used to talk about scientific facts. As you can see in the example above, we use the present simple in both clauses.

它通常用于谈论科学事实。 正如以上的例子:

太阳下山天空也就变黑了。

如果你按下该按钮，它会亮起。
