接下来需要为不同面板添加不同的脚本
1.在总的canvas下添加脚本
这个只是用来存储题目和最终分数
2.在答题面板下添加
Question Buttons 用来控制显示什么按钮
Question 用来读取txt并处理相关参数
按钮交互：（点击按钮是传入函数中不同的参数）
3.脚本
①QuestionCounts.cs
using System.Collections;
using System.Collections.Generic;

// Use this for initialization
void Start () {

// Update is called once per frame
void Update () {
