Question

分析句子结构，并翻译。句中that引导的是什么从句

Those factors are more than enough to make up for the squalor,disease and spectacular poverty that those same migrants must often at first endure when they become urban dwellers

Answer 1

主系表结构，主语Those factors，系词are表语more than enough，to make up for the squalor,disease and spectacular poverty不定式做表语的补语，that those same migrants must often at first endure是修饰squalor,disease and spectacular poverty的定语从句，when they become urban dwellers是修饰这个定语从句的状语从句。
当那些移民要成为城市居民的时候，他们往往必须先忍受肮脏，疾病和超乎想象的贫穷，但这些因素却极大的补偿了这些。
