定位能力(Scanning)：

　　通过扫读的方式，不需要逐词阅读，而只需要在文字间迅速移动眼睛，仅寻找相关的事实或细节。无需理 解每一个单词，只要理解到足以回答问题即可。

　　Example：

　　But there are limits to adaptation and loud noise becomes more troublesome if the person is required to concentrate on more than one task. For example, high noise levels interfered with the performance of subjects who were required to monitor three dials at a time, a task not unlike that of an aeroplane pilot or an air-traffic controller (Broadbent,1957). Similarly, noise did not affect a subject's ability to track a moving line with a steering wheel, but it did interfere with the subject's ability to repeat numbers while tracking (Finkelman and Glass, 1970).(C7T4P3)

　　做题过程：要在上述段落中迅速找到 Broadbent 和 Finkelman and Glass。
