问题 According to Richard Satava, the application of virtual reality to medicine______.
During virtual reality operations, the surgeon can have a better view of the cuts in the body because______.

选项 A、he is looking at the cuts on a computer screen
B、the cuts can be examined from different angles
C、the cuts have been highly magnified
D、he is wearing 3-D glasses

答案B

解析 从最后一段"surgeons are wearing 3-D glasses for a better view"可知,在虚拟现实条件下的手术通过计算机和微型相机的帮助,使得医生能够在屏幕上从不同角度看到伤口的三维图像,因而有一个更清晰的视野,所以答案要在B和D之间选择。但是D是表面原因,而B却是本质原因,所以选B。
