A man may select a woman because he, in his own eyes, sees her as the just-right wife for him

A man 主语，may select 谓语，a woman 宾语

because he, in his own eyes, sees her as the just-right wife for him
整个是原因状语从句，作状语

在这个状语从句中，紧跟在because后面的he 是从句的主语， sees是从句的谓语，her是从句的宾语，as the just-right wife for him是从句中宾语her的补语（即介词短语做宾语），in his own eyes是从句的状语，可以放在he的前面， （即……because in his own eyes，he sees her as the just-right wife for him）

祝进步↖(^ω^)↗

楼上的答的不错 就纠正一点 in his own eyes是插入语哦 并非状语。

一个男人可能选择一个女人的理由是因为在他的眼里，将那女人视为他的适合配偶。
