问题     Some of today’s most cutting-edge technology is now being used to help students with special needs. No longer just the province of games for "video needs", virtual reality has come into its own as a tool for special education teachers and therapists. As such, it is used for assessment, teaching, and practice, according to Skip Rizzo, research assistant/professor at the University of Southern California.
    For example, virtual reality has been used effectively to assess students’ depth perception, with the results being quite different from those obtained from traditional paper and pencil tests. It is also used to help students gain transition skills: Students with autism or developmental delay can visit a virtual supermarket, take public transportation, cross the street, or organize his or her day. Students in wheelchairs can learn how to navigate buildings. And the beauty is, these students can make any number of mistakes without endangering themselves.
    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.
According to the text, what is the ultimate purpose of virtual reality in education?
选项 A、To give special students a chance to experience life in the outside world.
B、To train teachers to work with students with special needs.
C、To allow special students to learn life-skills in a safe environment.
D、To prepare special students to transition into mainstream society.
答案D
解析 属事实细节题。题目中的关键词ultimate purpose其实是原文最后一句中的the mostimportant function的同义替换，这是出题人常用的出题技巧。但要回答此题还需要了解本句中this的指代内容。联系上一句内容可知：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。由此可知，选项D正确：虚拟现实运用到教育中的最根本的目的是为这些有特殊需要的学生进人现实主流社会做准备。其他选项都不是虚拟现实教育的最终目的。
