卫生类职称英语备考句型：

To hear him talk...

结构：To hear him talk，+主要子句

说明：此句型意为“听某人谈话(的口气)…”。从形式上看，To hear him talk 似为不定式词组，但实则为含蓄条件句(即不用 if 直接引导)。To hear him talk 相当于 If you could hear him talk。

To hear him talk,you'd think he was Prime Minister.

听他谈话(那口气)，你会以为他是首相呢。

To hear you talk,I'd think you were Prime Minister.

听你谈话(那口气)，我还以为你是首相呢。
