为什么第一句括号中单词用ed形式,第二句括号中单词ing 形式? In that area,many days are trained to look for people (trapped) in the snow. The largest number of people (speaking) English may be in China.
这两个句子都是分词作后置定语的用法. 第一个 people trapped in the snow = people who are trapped in the snow,其中 trapped 是被动语态,即人是被困在大雪中的. 第二个 people speaking = people who speak,其中 speaking是主动语态,指说英语的人.
