替换前:Such an experience befell a certain young girl the first time she was traveling alone.(一个小姑娘第一次单独出门就碰到了这种情况。)——《新概念英语》
这句话中时间状语“the first time”的定语从句为“she was traveling alone”,省略了关系副词“when”或“that”(关系副词一般只有在非正式文体中才能省略吧,为什么在这句话中也能省略呢?);
替换后:Such an experience befell a certain young girl who was traveling alone the first time.
这句话中的宾语“a girl”的定语从句为“who was traveling alone”。
