问题描述：
I caught the child just in time before he fell into the river.
just in time 和before he fell into the river的关系是并列的吗?是并列做句子的状语,还是
before he fell into the river修饰 just in time
答
1.两者为并列关系,都做句子的时间状语.
严格讲,后来的这个时间状语从句是对just in time的详细说明.
2.如果用before he fell into the river修饰just in time,岂不是前者要做定语从句/同位语从句,但是before不可能做定语从句/同位语从句的引导词.
