The thief followd her,with his eyes 【fixed】 on the wallet in her pocket
考点：介词with的复合结构.
关键知识链接：
固定短语:
fix one's eyes on sb/sth 变为被动：one's eyes be fixed on sb /sth
注视,凝视,盯着;将目光集中于；目光被集中于用于介词with的复合结构时,介词with的宾语【his eyes 】和后面动词【fix】是被动关系,即【目光被集中于 】,因此,用过去分词.Anna was reading "war and peace",completely【lost】to the outside world.=Anna was reading "war and peace",【and he was】completely 【lost】to the outside world.
考点：过去分词短语作状语知识链接：sb be lost in/to sth:埋头于；沉湎于
be completely lost in完全沉浸于
例句：
Anna was reading a piece of science fiction,completely lost to the outside world.
安娜正在读一本科幻小说,她完全沉浸在此书中了.
【注意】：过去分词作状语,这种考查形式,不能单纯使用与主语的主动、被动关系来判断.再如：
【Worried】about the safety of their children ,many parents went to pick their children up after school.
祝你开心如意!
