Part II：语法学习
条件句
概念解释：表达的过程中经常会遇到表示条件的情况，这就是条件从句诞生的原委。需要大家记住的有两点：
第一，条件从句表示将来的含义，但形式上必须保持一般现在时的状态。
示例1：If you park your car in the wrong place, a traffic policeman will soon find it.(其实还没有停车，表示的是将来的情况或者最起码是一般的情况，但却是用一般现在时来表示，主句里面则用了将来时与之配合)
示例2：You will be very lucky if he lets you go without a ticket.(还没有发生的事情，但用的是一般现在时，主句则用将来时)
示例3：You will enjoy your stay here if you pay attention to our street signs.(条件句中的一般现在时与主句中的将来时配合)
示例4：If you receive a request like this, you cannot fail to obey it.(条件句中的一般现在时与主句中的将来时配合)
