function Car(brand, color, displacement) 
    this.brand = brand;
    this.color = color;
    this.displacement = displacement;
    this.info = function() 
        return `颜色为$this.color的$this.brand，排量为$this.displacementT。`;
    


function Person(
    brand,
    color,
    displacement,
    name,

    Car.apply(this, [brand, color, displacement]);
    this.name = name;
    this.say = function() 
        console.log(`$this.name买了一辆$this.info()`);
        // 半晨买了一辆颜色为寒山暮紫的五菱星辰，排量为1.5T。
    


let infomation = 
        brand: '五菱星辰',
        color: '寒山暮紫',
        displacement: '1.5',
        name: '半晨',

person.say();
