请分析一下这个英文句子
few people have quietly changed the world for the better more than this rural from this mild-western state of Iowa in the united states
从句型和词用法各个方面
答
这个来自美国中西部爱荷华州的乡下人默默地改善了世界.这还很少有人做得到.
应该是mid-western.不是mild-western.
主语：people
谓语：have changed
宾语：the world
quietly,for the better 和 more than this rural 都是修饰谓语的.
from this mid-western state of Iowa in the united states是定语修饰rural
