Question

这是新3练习里的一句话：the car headlights were on and its horn blaring as the thieves wanted to warn people out of their way,（车灯亮着、喇叭鸣叫着,因为小偷想警告人们让出道路.）我知道its horn blaring 是独立主格成分,但and连接的应该是两个相同的东西,and前面the car headlights were on 是句子,后面由是独立主格（不是句子）,语法上讲不通,这是怎么回事?

Answer 1

its horn blaring这个子句中承前省略的系动词was,即The car headlights were on and its horn WAS blaring as the thieves wanted to warn people out of their way.
