1.At that moment, with thecrowd watching me, I was not afraid in the ordinary sense, as I would have beenif I had been alone

2.The bad news was that hecould be a very dangerous person he choose to be

向劉老師請教，句子1中 would have been 后為什么可以省略 afraid，句子2中choose to be 后為什么可以省略 a very dangerous person

?I was not afraid in the ordinary sense,?as I would have been if I had been alone.

黑體部分= as if I had been alone. 這是as if從句展開的形式。又如：

The man lay there motionless, as if he were dead.?

= The man lay there motionless, as he would be if he were dead.?
