The current world chess
champion, who won the title in 2021, is from Norway.请问老师,who修饰champion还是The current world
chess champion?如果是后者,为什么定语从句也可以修饰其中的定语呢
They say it would cost too much for the American economy to move away from using oil and other fossil fuels.这句的for the American economy应该不是动词不定式逻辑主语吧,我感觉像是状语修饰谓语,意思是“对于……来说”。
