Difference between が and は?

Hello! I’m Brazilian and I’m studying Japanese.
Does anyone know the difference between the particle が and the particle は? Can you explain me please?

Thanks (:

I’m not a tutor here, but I’m Japanese.
However, I don’t know much about grammatical explanation of our language. I’ll try to give you some hint to your question.

kare wa Tanaka san desu.
He is Mr.Tanaka.
This is a normal sentence.

KARE ga Tanaka san desu.
HE is Mr.Tanaka.
When we emphasize the word “kare”, we use が instead of は。
In this situation, we imagine that there are two or more persons and someone point Mr.Tanaka out of the persons.

I think there are other usages of は and が. It’s difficult for me to explain it.
I suggest you to read and listen a lot of Japanese sentences. You will be familiar with the usage of は and が in Japanese.

I hope this helps you.

1 むかしむかし おじいさん(が)いました。
2 おじいさん(は) 芝刈りにいきました。

最初のおじいさんは初出場で、いわゆるan old manですが、2のおじいさんは既に
この話を聞いている人のなかで具体化されているのでthe old manということだとか。
極論すると が=a an, は=the と考えられるとか、なんとか。

のあるときに 英語にしてみますね。
