2018屠屠考研英语长难句 一日一句(33)

每日一句：

Additional social stresses may also occur because of the population explosion or problems arising from mass migration movements—themselves made relatively easy nowadays by modern means of transport.

【分析】

句子主干结构是Additional social stresses may also occur；because of后面有两个宾语the population explosion 和 problems；名词problems带有现在分词短语作后置定语arising from mass migration movements； themselves作为代词，指前面的名词短语mass migration movements，充当同位语作用，后面的过去分词短语made relatively easy是themselves的后置定语，by modern means of transport是方式状语，解释变得容易的原因。

【词汇】

population explosion人口爆炸

arise from源自于

migration移民

means of…的方式

【译文】新的社会压力出现，是因为人口猛增或大量人口流动——是现代交通工具使人口流动变得相对容易。
