Tom was the only one of the lookers-on who was willing to help.thanks!

问题描述:

Tom was the only one of the lookers-on who was willing to help.thanks!

你不理解的是句型还是单词?
我来解说下吧:
lookers-on——围观的人,周围的人等
把插入语(就是不影响句子大意的语句)去掉,句子的主、谓语找出来——Tom was willing to help(汤姆愿意帮忙)
再把插入语带上一起翻译———汤姆是围观的人中唯一愿意帮忙的人.
请多多指教,不懂再hi偶.
