my name is moises I from Spain and I'm learning English, to be honest my speaking skill is rather poor but I would like to send you some phrases or writings so as you can correct them for me. the truth is I don't trust on those online dictionaries. I don't want you to translate into Spanish,what I really want is how would you say what I'm writing you. for example this phrase:

-"they told him a secret and made him to swear not to tell anyone" 
How does it say in pasive voice? heres the answer I think it is (please correct them if they're wrong)

1_ paul was told a secret and he was made to swear not to tell anyone.
2-he was made to swear not to tell anyone a secret they had said to him.


THANK YOU
