谁能帮我分析下这个句子的句型结构，急～If he lives in a city, as most users do, then his fellow city-dwellers and the buildings, cars and streets around them are throwing off almost unimaginable quantities of valuable data from which he will benefit

Answer 1

If 引起条件状语从句，he主语，lives谓语，in a city状语，as most users do 比较状语从句，most users 主语，do谓语。
主句：主语 his fellow city-dwellers and ...them, 谓语are throwing off , 宾语 almost unimaginable quantities of valuable data, 定语从句 from which he will benefit。定语从句中：主语he，谓语will benefit , 状语from which ，which 关系代词，代替data，在定从中作介词from的宾语。
