phrasal verbs

[Englishfinger]

Hi,
I´d like asking you if these phrasal verbsand expressions are correctly used:
Please, sign the contract once and for all. At any rate, you can take down your opinion and reject it .
If Bob has taken Mary in by all means, could you say that Mary has been taken in by Bob by all means?
She has taken on so much work that she is getting aggressive to some extent. In my opinion, she should have turned some work down.
I am not getting along with the font colour or size icons, so I couldn´t underline the phrasal verbs.
I am learning, please correct all my mistakes.
Thanks in advance. This is a very useful learning way.
My best wishes

I'm not sure I understand what you mean by "take down" here.

"Take in" means to grant residence in one's home, usually free of expense. It also means to reduce the width of something, such as the waist of pants. I don't understand it in your text.

You have used "take on" correctly. "Turn down" is correct.

"Get along" works with people or animals.

Hi Mordant,
First of all, thank you for your quick answer. You know, when somebody is learning an unknown language, all kind of rare combinations might be likely to appear. Spanish is my native tongue. That´s why I´ve confused take down by take back. I´ve looked these phrasal verbs at the Cambridge Dictionary and at Using English page. I tried to mean in the sentence: At any rate, you can take down your opinion (change your opinion). I paste the definitions to make it clearer: Phrasal Verb: Take back Meaning: Retract a statement, admit that something was wrong
Example: I had to TAKE BACK everything bad I'd said about them when I learned how they'd helped out.
to admit that something you said was wrong
I take back everything I said about George - he's been really nice to me recently.I know I said he was arrogant and unfriendly but I take it all back now.
In this sentence: If Bob has taken Mary in by all means, could you say that Mary has been taken in by Bob by all means? (Bob fooled Mary)
to deceive someone, or to make someone believe something that is not true
I can't believe she was taken in by him. [usually passive]
Phrasal Verb: Take in
Meaning: Deceive
Example: She TOOK me IN with her story until someone told me the truth.
Sorry if I´m wrong, this is the only way I have to practise phrasal verbs, for this reason I ask for help because sometimes the definition does not match with the common usage.
Thanks for all your work!
