高中英语分词问题

Question

The thief followd her, with his eyes ------ on the wallet in her pocket.

A fix B fixed C fixing D to fixed

Anna was reading "war and peace", completely_____to the outside world.

A being lost B having lost C losing D lost

这两个题分词与逻辑主语都是主动关系，为什么不选ing形式，却选过去分词形式？

Answer 1

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！

Answer 2

be fixed on 固定搭配 “钉在……上” his eyes were fixed on “眼睛盯着……”
be lost “迷失”
两个都是固定搭配

Answer 3

第二题，先lost，是用lose的过去分词lost,句子表面意思是：完全被外面的世界所遗弃。也就是她沉湎于WAR AND PEACE之中了，对外界毫无知觉了。
