Question

为什么用compared不用comparing

Answer 1

译文：相比传统的贸易方式，他们不必花钱去租房。
词组：A be compared with B（意思：比较）被动，所以用compared。

Answer 2

用compared (过去分词=past participle of compare);在这里, 'compared' 是形容词!

Compared is an adjective: it is a participle, a form which is so called because it 'participates' in
characteristics of both nouns and verbs.
