Question

一道英语改错题

Won its war for independence in 1783, the United States then struggled to establish its own economic and financial system.
这句话错在哪里,请改正.
请说明原因!!!!!!!!!!!!!!!!!

Answer 1

分词作状语，主要看是主动还是被动，美国赢得应该是主动,所以Won错，改won为winning

Answer 2

won 改为winning 也不能改为 having won 因为有具体时间，不能用完成时态
应该是 主格结构

不然 won 前面要有主语

Answer 3

Won改成Had won

Answer 4

Won改成Having won

Answer 5

Having won its war....
