Como dizer "não é?" em inglês

Do you know that very end of a sentence when we ask for a confirmation of what we've just asked? I'll give some examples:

Can anyone help me?

Please, don't be shy of correcting any mistakes I've made.
That's why it would be great if someone helped correct me.

Essa é uma boa ideia, não é? --> This is a good idea, isn't it?
Você concorda comigo, né? --> You agree with me, don't you?

Para você usar corretamente uma "tag question", é preciso estar atento para o tempo verbal usado na frase que a antecede, pois será o mesmo tempo usado na "tag question". Depois, basta inverter a forma: se a frase estiver na afirmativa, a "tag question" fica na negativa e vice versa.

Simon, I didn't knew that...
This scheme of tag question is all new to me. I usually say "isn't" in the end of all my sentences when I want to use the expression. "não é?".

From now I'll pay more attention on the words I say.
But thanks very much.


And Thomas, I'm grateful for your examples. They will surely help me to improve my vocabular. Thanks a lot!

Canadians used to say "eh!" at the end of the sentences. It's almost like our "né?".
