题目

the old engineer’s eyes still shone bright in the wrinkled brown face and his step as he came across the room was steady ,though slow.
这句话的as he came across 在句中作什么成分?为什么跟在主语后面?还有though slow为什么要用逗号与前面隔开?
as不是连词吗？为什么前面的and后不是完整的句子？

答案

as he came across the room做时间状语从句,它可以放在句首句中句末,thou slow 是让步状语从句though his step was slow 的省略形式,故用逗号.满意请采纳,谢谢
