Yet this inert fleck (小片), still unfamiliar to the (54) majority of Americans, has astonishing power. It is cheap to (55) produce, fast, infinitely versatile and convenient.
The miracle chip represents a quantum(重大的) (56) in the technology of mankind, a development that (57) the past few years has acquired the force and significance associated with the development of hand tools or the discovery of the steam engine. Just as the Industrial Revolution (58) an immense (59) of tasks from men’s (60) and enormously expanded productivity, (61) the microcomputer is rapidly assuming huge burdens of drudgery from the human brain and (62) expanding the mind’s capacities (63) that man has only begun to grasp.

选项
A、freight
B、passenger
C、relaying
D、switching
答案
D
解析
此题属于语义搭配题。switch意为“改变,交换”,如:switch position(改变立场),又如;They switched the train to the other track. 他们将火车转到另一条轨道。原文中提到与铁路有关的一个场所,应是道岔所在地,有许多轨道,故选项D switching正确,意为“铁路车辆编组场”。选项A freight意为“货运”;选项B passenger意为“乘客”;选项C relaying意为“转播”。
