一、各題主題揭示對話主題
　　將各題所考查的主題內容結合在一起，往往可得出整篇對話的主題。如果某一題目是考查對話主題，其中的一個選項明顯能夠概括其他各題選項的內容，那么該選項很可能為答案。

　　【聽前預測】
　　預覽三道題各選項，由19題中的 interview, applicants, vacancy, advertise for a manager, apply for a job 等詞語可以推測對話與刊登招聘廣告或應聘工作有關。而20題中 hardworking, ambitious, good at managing his time, with practical working experience, with his own idea 等詞語則表明對話中還涉及到對所招聘人員的要求。
