2018屠屠考研英語長難句 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】

句子主幹結構是Additional social stresses may also occur；because of後面有兩個賓語the population explosion 和 problems；名詞problems帶有現在分詞短語作後置定語arising from mass migration movements； themselves作爲代詞，指前面的名詞短語mass migration movements，充當同位語作用，後面的過去分詞短語made relatively easy是themselves的後置定語，by modern means of transport是方式狀語，解釋變得容易的原因。

【詞彙】

population explosion人口爆炸

arise from源自於

migration移民

means of…的方式

【譯文】新的社會壓力出現，是因爲人口猛增或大量人口流動——是現代交通工具使人口流動變得相對容易。
