改变语言顺序：模板方法模式（Template Method Pattern）是一种行为型设计模式，它定义了一个算法的骨架，将具体实现延迟到子类中。模板方法模式通过把不变的行为放在父类中，把可变的行为放在子类中，来提高代码的复用性和扩展性。

Template Method Pattern is a behavioral design pattern that defines the skeleton of an algorithm, but defers the implementation of certain steps to the subclasses. The purpose of the Template Method Pattern is to improve code reuse and extensibility by placing invariant behavior in the superclass and variant behavior in the subclasses.
