　　But the human mind can glimpse a rapidly changing scene and immediately disregard the 98 percent that is irrelevant, instantaneously focusing on the monkey at the side of a winding forest road or the single suspicious face in a big crowd. [2002, text 2]

　　分析：

　　A.句子结构拆分：But the human mind can glimpse a rapidly changing scene and immediately disregard the 98 percent that is irrelevant, //instantaneously focusing on the monkey at the side of a winding forest road or the single suspicious face in a big crowd.

　　B.分析句子结构：该句的主干是the human mind can glimpse a scene and disregard the 98 percent，其中现在分词changing作定语修饰scene。that is irrelevant是由that引导的定语从句修饰限定先行词the 98 percent。现在分词短语focusing on the monkey at the side…作状语。

　　C.词汇点拨：glimpse意思是“瞥见”;scene意思是“场面，情景”;disregard意思是“忽视”;instantaneously意思是“即刻”;suspicious意思是“可疑的”。

　　D.参考译文：但是人类的头脑可以只迅速地瞟一眼一个快速改变的场面，然后立即放弃98%不相关部分，马上聚焦于一条崎岖森林道路边的一只猴子，或者在茫茫人海中的一张可疑的脸。
