Question

Many people over 65 are left sounding much older than they are.的句子成分

Answer 1

主语: Many people over 65
谓语: are left 是被动语态
主补: sounding much older than they are.是现在分词短语作主补.

此句若还原成主动语态则为:
(voice) leaves many people over 65 sounding much older than they are。
在主动语态中, sounding much older than they are现在分词短语做宾语补足语.
变成被动语态后,就成了主语补足语.
sound和many people over 65在逻辑关系上为主动形式,故用现在分词sounding .

句意:很多65岁以上的老人听起来要比实际年龄老。
