	        this.name = name;
	        this.sex = sex;
	    }
	    public String getName() {
	        return name;
	    }
	    public void setName(String name) {
	        this.name = name;
	    }
	    public String getEnglishName() {

        m.put("liSi", new Student("李四","女"));
        m.put("WangWu", new Student("王五","男"));
