3 sentences in the idioms part of manhattan sc guide

[liu1993918]

After I read all the sentence in the idioms part in the SC guide, I have some questions.

First, a right sentence: the idea developed into a project.
However, in my opinion this sentence should be: the idea is developed into a project.

Second, another right sentence: I lose my books whenever I LAY them down. (present tense of different verb)
I cannot understand the "(present tense of different verb)" part.
In my views, we should use "lie", because it is present tense.

Third, the last right sentence: she REQUIRES OF her friend THAT work BE done. (subjunctive)
I am confused about the usage of "of" here.
Is the meaning of this sentece differ from another sentence—she requires that her friend do work?

Thanks in advance.
I know I ask some stupid questions.
