It is not necessarily a selfish notion, because achieving the dream is assumed to make America strong. 不定式是作目的状语还是主语补足语？

【答】译文：这可能不是个自私的想法，由于达成梦想被觉得（意味着）是让美国强大。

assume + 宾语 + 不定式（宾补）：觉得/假定宾语做某事。转换为被动语态之后，宾语变成主语，宾补因此变成主补。所以，to make America strong在本句充当主语补足语。

I saw him taking their children to college.

to college是作taking的目的（地址）状语，还是作宾语补足语？请解析

【答】to college是地址状语，它修饰take，表明take的目的地。
