But the human mind can glimpse a rapidly changing scene and immediately disregard the98 percent that is irrelevant, instantaneously focusing on the monkey at the side of a windingforest road or the single suspicious face in a big crowd.

　　词汇突破：

　　glimpse 快速的看一眼;

　　Disregard 抛弃，丢弃

　　Irrelevant 不相干

　　Instantaneously 立即

　　Winding 蜿蜒曲折的

　　Suspicious 可疑的

　　主干识别：the human mind can glimpse a rapidly changing scene and immediatelydisregard the 98 percent

　　并列的两个动词 glimpse和disregard

　　其他成分：that is irrelevant 修饰 the 98percent;

　　focusing on the monkey at the side of a winding forest road or the single suspicious face ina big crowd.

　　现在分词短语做状语，focus 的动作发出者就是句子主语human mind;

　　微观解析：the monkey or the single suspicious face 为focus on 的并列宾语

　　难点揭秘：动词的并列在主句中出现;而在现在分词短语中出现并列宾语;

　　译文赏析: 但是人类的大脑可以只对一个快速改变的场面瞥一眼，就能立刻放弃98%的无关信息，马上聚焦于崎岖的森林道路旁的一只猴子，或者在茫茫人海中的一张可疑的脸。
