例108　When CareerSite's agent sends out messages to those who have signed up for its service, for example, it includes only three potential jobs—those it considers the best matches.

【结构分析】for example点明了这个句子和前一句之间的关系；举例说明前面一句话。该句子的主干是：it includes only three potential jobs。when引导时间状语从句when CareerSite's agent sends out messages to those who have signed up for its service，里面有定语从句。破折号后是potential jobs的同位语，中心词是those，后面接定语从句，句子中的it回指CareerSite's agent。

【亮点回放】此句话的亮点在于超级时间状语从句的使用，该时间状语套有定语从句，很经典。

【核心词汇】
