For example:

wear jeans to school , you’ll be sorry.

1. Structure
这里if所引导的是真实条件句(real conditional), 即所
假设的条件有可能成为现实, 表达假定所假设的条件
实现时会出现的情况或会采取的行为。有时, 我们
可以使用并列结构的祈使句来表达这种类型的条件句。
e.g. If you set your alarm clock, you won’t oversleep.
如果你上闹钟, 你就不会睡过头了。
Set your alarm clock, and you won’t oversleep.
If you give him an inch, he will take a mile.
他会得寸进尺。
Give him an inch, and he will take a mile.
If you don’t give him some food, he will starve.
如果你不给他一点吃的, 他就会饿死。
Give him some food, or/else he will starve.
(1)条件状语从句通常由连词if引导, 意为“如果、假如”,
主句不能用be going to表示将来, 而应该用shall、will。 e.g. If you leave now, you are never going to regret it.
(错误) If you leave now, you will never regret it. (正确)
(2) if “如果”, 引导条件状语从句, 主句用一般将来时，
从句则用一般现在时，如： If it rains tomorrow, I shan’t climb the hills.
2. 用法
注意: 宾语从句中的if与条件状语从句if的区别。
宾语从句中的if “是否”相当于whether, 引导
宾语从句, 时态需根据语境确定。 I don't know if it will rain tomorrow.
我不知道明天是否会下雨。
1.如果你不赶快走, 你就会迟到。
2 .如果你爱你的父母, 你应当帮他们做做家务。
3. 如果你更友善一些, 你会教上很多好朋友。

some pieces of advice一些建议。
