个人认为是The crowd began to shout.The drunk was unaware of the danger.
是两个句子,或者中间缺少连接成分.哦The crowd began to shout,but the drunk was unaware of the danger.

这样呢，求句子成分。。。。那就是两个简单句子啊用but连接，表句子并列吧谁是主谓宾或主系表，那句是状语The crowd（主） began to shout（谓）,but the drunk （主）was unaware of the danger.

be unaware of 没有意识到，这里是谓语的位置，印象中是系表结构之类？
