for someone to do something

[aysaa]

Hi,

Sorry, but I can't figure out how to use 'for someone to do something' in a sentece. Could you please tell me how to use it?

1.I wrote my second essay for you to review.

2.I punished her for you to understand that it is allowed for smoking in this age.

I made 2 sentences, but I don't know if they are OK or not.

Thanks.

Your first sentence is fine, but the second makes no sense. Why should you punish someone so that a third party can understand that something is allowed?

It would be 'not'. Sorry.

I punished her for you to understand that it is not allowed for smoking in this age.

I punished her for you to understand that it is not allowed for smoking in this age.

It still seems a strange thing to say. Even if expressed less unnaturally, for example as, I punished her so that you would understand that people of that age are not allowed to smoke, I find it difficult to imagine a natural context in which it could be said.
