值得一提的是，职业咨询区人流如织，已成为本次活动最热火朝天的区域之一。(It)

It is worth noting / mentioning that the career consultation area is packed with visitors, and becomes / making it one of the most dynamic / lively sections of the event.

考查时态、非谓语、固定句型和主语从句。表示 “值得一提的是” 用固定句型It be worth noting / mentioning that ...，其中It作形式主语，真正的主语是that引导的主语从句，本句描述一般事实，时态用一般现在时，be动词用is。主语从句中：表示 “职业咨询区” 用the career consultation area，作从句的主语；表示 “人流如织” 即 “挤满了人” 用be packed with visitors，其中be packed with是一个固定短语，表示 “挤满了”；主语为第三人称单数，be动词用is；表示 “成为” 用become，用连词and连接谓语is和becomes；表示 “最热火朝天的区域之一” 用one of the most dynamic / lively sections of the event。或者表示 “使他成为” 用make it，用现在分词，作状语。故翻译为：“It is worth noting / mentioning that the career consultation area is packed with visitors, and becomes / making it one of the most dynamic / lively sections of the event.”。
