Question

he said with a smile as if he were talking about an old friend.这是新概念三册24课的课文 这里的 as if he were talking 为什么要用were， he后面不是要用was吗

Answer 1

这个属于虚拟语气用于条件状语从句中的情况。

表示与现在事实相反的假设,比如这里表示他好像在谈论一位老朋友，但事实是不是老朋友，条件状语从句中的谓语动词用“过去式（be动词的过去式用were）”,而主句中的谓语动词用“would / should/ could / might + 动词原形”.如：

I were a boy, I would join the army.

If the had time, she should go with you.追答

If she had time手误

Answer 2

简单来说，这是as if 引导的【虚拟条件句】，其中无论主语用第几人称，be动词一律用were。
但是，有时，口语和非正式文体中，也可以使用was。追答

例如
He talks about the accident as if he were at the scene.

追问

很感谢，想请问 无论是 I you she he 在这句话里都是were talking bout吗 一律用were,是吗

追答

你说的很对!

这是虚拟语气的规定。

Answer 3

虚拟，用were表示与事实相反。
