问题     In 1995 about 700, 000 robots were operating in the industrialized world. Over 500, 000 were used in Japan, about 120, 000 in Western Europe, and about 60, 000 in the United States. Many robot applications are for tasks that are either dangerous or unpleasant for human beings. In medical labs, robots handle possibly dangerous materials, such as blood or urine samples(尿样). In other cases, robots are used in repetitive, unchangeable tasks in which human performance might degrade over time. Robots can perform these repetitive, high-precision operations 24 hours a day without fatigue. A major user of robots is the automobile industry. General Motors Corporation uses about 16, 000 robots for tasks such as spot welding(点焊), painting, machine loading, parts transfer, and assembly. Assembly is one of the fastest growing industrial applications of robotics. It requires higher precision than welding or painting and depends on low-cost sensor systems and powerful inexpensive computers. Robots are used in e-lectronic assembly where they load microchips on circuit boards(线路板) 。
    Robots are being used to help doctors in installing artificial(人工的) legs, and very high-precision robots can help doctors with difficult operations on the human eye. [br] Which of the following is the best topic about this article?
选项 A、Robots
B、Uses of Robots
C、Development of Robots
D、Advantages of Robots
答案 B
解析 根据文章的整体意思来做。第一段通过举例说明机器人使用的数目、领域、条件等等。第二段强调机器人使用的环境。所以整体上来说，这篇文章主要说明了机器人的应用。故正确的答案为B。
