1. We use real conditionals to talk about a result based on something that might happen. 

我们用真实条件句谈论基于真实可能发生的事情的结果。

2. To make a real conditional, we need two parts: 'if' clause + the results.

真实条件句由两部分组成：“if” 从句 + 结果。

3. For the 'if' part, we use a present tense, for the results part, we can use 'will' like the future.

引导的从句用一般现在时，表结果的句子用一般将来时。

If it rains tomorrow, I'll bring an umbrella.
