before后的时态问题
My mother often takes a long walk before ______(go) to bed.
答案是going 为什么?before在这里做什么成分?

before后的时态问题My mother often takes a long walk before ______(go) to bed.答案是going 为什么?before在这里做什么成分?
My mother(主语) often(频率副词,做状语) takes(谓语) a long walk(宾语) before (连词,引导时间状语从句)going to bed(动名词名作主语的时间状语从句,相当于I go to bed

其实,这里going不是表示进行时,before后要接句子即从句,如果完整的表达应该是before she goes…,这里省略了she,则用going!这应该是高中要学的一种语法!好久没看,名字记不得了!

before是介词,后面跟动名词构成介宾短语。因为动词变为ing就可以“看作”词性变成名词了,就可以满足“介词后面需要跟名词”的约束条件了。
