First/Real conditional

尖

\'Condition sentences\' 表示情况以及因为该情况而产生的结果。如果该情况属实的几率较高，那就是 \'Real conditional sentences/ First conditional sentence\'.
\'Real condition\' = 真实条件

表述条件的句子要用 \'if\' 开头
\'if\'= 如果

If I see Peter, I'll tell him to call you. = 如果我见到\'Peter\'的话，我会叫他打电话给你的。

在这里 \'I\' 见到Peter是一个属实几率高的条件，所以这是个\'real condition\'。
这里 \'if I see peter\'= \'conditional clause
I'll tell him to call\' = \'main clause\'.

If I arrive before 5, I will give Wang Jing the message. = 如果我在5点之前到的话，我会给Wang Jing传话的。

当不确定\'if\'开头的句子中的情景是否会发生时可以用\'will\'。在这句话中，'I'预计自己会在5点之前到达。

If I should arrive before 5, I will give Wang Jing the message/
Should I arrive before 5, I will give Wang Jing the message = 要是我在5点前到的话，我会给Wang Jing传话的。

这里 \'I\' 5点钟能到达的几率不高，因此要用 \'should\' 。

尖

You will miss the bus if you don't run = 如果你不跑的话会错过巴士的。

在负义的‘first conditional’句子里,我们可以用‘useless’来代替‘if + not/don't’。

You will miss the bus unless you run = 除非跑着去，不然你就会错过巴士的。

当我们使用‘Unless’的时候，这句话已经显示出负义的情形，所以我们不需要再使用‘not/don't’。
