请教一个英语句子是不是病句
As they got to the steps,and the wall of the house shook.
出自人教版英语课本第一册第四单元课文The Rescue
as引导的是什么从句?时间状语从句吗?为什么这里从句和主句之间用and连接?是不是病句?

Answer 1

如果确定这是一个“句子”的话,那么是个病句.
前半段：As...steps,...是个时间状语从句,当……时…… 那么后半段主句呢?
由于...and...是连接两个并列成分的,即使后面有内容,也仍然是As-从句的一部分,问题依然是“主句呢?”：改法只要把and 去掉就行.
As they got to the steps, the wall.
As they got to the steps and the wall of the house shook, they were too scared to remain still. (This is also right by adding a main-clause and incorporating " and the wall..." as part of as-clause.)
