1. If you hear a comedian telling jokes about the way people behave when they queue up in lines, or asking why it only rains when you forget your umbrella, you are listening to an observational comedian. (P2)
分析：此句是一个复合句，if引导条件状语从句，主句是you are listening to …。在此条件状语从句中，or连接的telling jokes about…和asking why…作comedian的宾语补足语。在第一个宾语补足语中，people behave是定语从句，先行词是the way，紧接着是when引导的时间状语从句；第二个宾语补足语中，why引导的句子作asking的宾语，其后也有一个when引导的时间状语从句。例如：
I heard Tom singing when I entered the room.
