问题     In fact, one of the biggest virtues of virtual reality is that it allows students to learn in a safe environment, and this holds true for students with behavior disorders. After a student has learned an appropriate behavior or way of controlling his or her anger, the student is put in progressively more difficult virtual social situations where he or she can practice the new technique. And it is expected that future teachers will be exposed to virtual classes, complete with "difficult students" to help them master behavior management techniques.
    Virtual reality even allows us to tailor the world to meet a child’s needs. Let’s say we’re teaching a child to cross the street by paying attention to traffic signs. Educators have found that it is often difficult for the child to locate the traffic sign in a busy environment.  With virtual reality, we can blow up the "walk sign" so the student knows what it looks like. Then we gradually begin shrinking the sign and adding other environmental elements. Once the student has mastered this virtually, he or she transfers the knowledge to the real world. In the end, this is the most important function of virtual reality programs for special students.
选项
答案 事实上，虚拟现实最大的好处存于它使学生在安全的环境中学习，而这一点对于那些行为失调的学生同样适合。学生学会某种适当的行为举止或者学会控制自己的情绪之后，就会置身于难度越来越大的虚拟社交场合，练习自己学会的新技巧。在未来，教师有望接触有“难对付的学生”的虚拟课堂，通过这种方式掌握行为管理技巧。 虚拟现实甚至还能让我们改变周围的世界以满足孩子的需求。比如，我们教孩子过马路时要注意看交通信号灯。教育者们发现，孩子通常很难在乱糟糟的环境下找到交通信号灯；但是借助于虚拟现实我们可以放大“行走信号”，让学生知道它是什么样子，然后逐渐将其缩小并添加周围的景物。一旦学生确实掌握了这一虚拟世界的法则，他或她就会将之用于现实世界，而这也是虚拟现实课程对于有特殊需要的学生来说最重要的功能所在。
