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.
The underlined word "fatigue" in the first paragraph can be explained as______.
选项
A、rest
B、paying
C、powering
D、being exhausted
答案
A
解析
文章中间部分提到“Robots call perform these repetitive,high-precision operations 24 hours a day without fatigue.”说的是机器人可以一天24小时不断的做那些重复的高精确度的工作而不‘fatigue’,因此我们可以推测其意思为“疲劳,劳累”。故正确的答案为A。
