问题 These instruments, which break up structures only to examine them more fully, demonstrate how details can be ______ and separated from the whole.
选项 A、amplified
B、magnified
C、exemplified
D、signified
答案B
解析 动词辨义。amplify意为“增强，放大”，指加强、放大无线电讯号、声音、电流等，也指扩大、扩展某一事物的范围，如：A laser is a device that amplifies light and makes it brighter.(激光是一种放大光线并使其更加明亮的装置。)magnify意为“放大，扩大”，指某个物体的扩大或增加，如：This microscope magnifies an object 100,000 times．(这个显微镜将物体放大10万倍。)exemplify意为“例证，举例说明”，如：The recent oil price rises exemplify the difficulties which the motor industry is now facing．(最近的石油涨价是汽车工业正面临困难的一个例子。)signify意为“表示，意味”，如：He signified his content with a nod．(他点头表示同意。)句中指放大细小的结构，以便对其进行全面的研究，故应选B)。
