1.stunned and hesitated 是本句的谓语动词,是主语people发出的并列动作意思是(这些人)吃惊所以.犹豫回答.而前面的wearing 短语是现在分词短语做后置定语修饰前面的名词people,且动作是主语发出所以用现在分词表示主动关系.意思是穿得很好的抱着狗的那些人.
再如 boys playing on the playground are from our class.
2.with their puzzled eyes wide open不是独立主格而是with的复合结构做伴随状语,open是形容词做宾补.是复合结构中宾语的状态.这个短语的意思是:疑惑地睁大双眼.
再如 He was asleep with the door open.
