there was a major increase in immigration in the years that followed the first world war
问题描述：
there was a major increase in immigration in the years that followed the first world war
that followed the first world war,过去分词做状语为什么还要用that?
答
二战后的几年曾有过移民高峰期
that followed the first world war是【定语从句】修饰the years
that 是关系代词,引导定语从句句子成份是什么？分析了followed前有没有省略什么，比如主语没有， that 代the years 在定语从句中做主语。 there was（There +be 句型） a major increase（主语） in immigration （地点状语）in the years（时间状语） that followed the first world war（修饰the years的定语从句）
