He loved best to choose themes from the simple life of the

该句话主语为：He loved to choose themes。 the simple life of the poor是修饰theme的来源。the+形容词表示一类人,因此,后面的trials and hardships与the poor为所属关系,空里应该填whose是对的。 再问： 先行词在定语从句中做宾语成分，当先行词提前，则宾语省略，可是whose 后面的从句没谓语啊 再答： 把从句拆解为the poor knew trials and hardships of his simple life so well by bitter experience。因此knew为从句里的谓语。再问： 原句不是he knew？ 再答： 对不起，正确的解释应该是He know the poor's trials and hardships so well by bitter experience。我同意落红霏霏的解释~
