问题     Richard Satava, program manager for advanced medical technologies, has been a driving force in bringing virtual reality to medicine, where computers create a "virtual" or simulated environment for surgeons and other medical practitioners.
    "With virtual reality we’ll be able to put a surgeon in every trench," said Satava. He envisaged a time when soldiers who are wounded fighting overseas are put in mobile surgical units equipped with computers. The computers would transmit images of the soldiers to surgeons back in the U. S.. The surgeons would look at the soldiers through virtual reality helmets that contain a small screen displaying the image of the wound. The doctors would guide robotic instruments in the battlefield mobile surgical unit that operate on the soldier.
    Although Satava’s vision may be years away from standard operating procedure, scientists are progressing toward virtual reality surgery. Engineers at an international organization in California are developing a tele-operating device. As surgeons watch a three-dimensional image of the surgery, they move instruments that are connected to a computer, which passes their movements to the robotic instruments that perform the surgery. The computer provides feedback to the surgeon on force, textures, and sound.
    These technological wonders may not yet be part of the community hospital setting but increasingly some of the machinery is finding its way into civilian medicine. At Wayne State University Medical School, surgeon Lucia Zamorano takes images of the brain from computerized scans and uses a computer program to produce a 3D image. She can then maneuver the 3D image on the computer screen to map the shortest, least invasive surgical path to the tumor. Zamorano is also using technology that attaches a probe to surgical instruments so that she can track their positions. While cutting away a tumor deep in the brain, she watches the movement of her surgical tools in a computer graphics image of the patient’s brain taken before surgery.
    During these procedures—operations that are done through small cuts in the body in which a miniature camera and surgical tools are maneuvered—surgeons are wearing 3D glasses for a better view. And they are commanding robot surgeons to cut away tissues more accurately than human surgeons can.
    Satava says, "We are in the midst of a fundamental change in the field of medicine."
Virtual reality operations are an improvement on conventional surgery in that they______.

选项 A、cause less pain to the wounded
B、allow the patient to recover more quickly
C、will make human surgeon’s work less tedious
D、are done by robot surgeons with greater precision

答案D

解析 细节题。题目问的是虚拟现实手术是传统手术的进步的原因是什么。原文倒数第二段最后一句指出机器人医生可以更精确地进行手术,这与选项D“由精确度更高的机器人医生完成”相一致;选项A“减少疼痛”;选项B“恢复更快”;选项C“医生的工作不再乏味”都有一定的偏狭性。故选D。
