Question

qual o significado de 's, 're, 'm.(Como completar as frases com ela)

Answer 1

Esses 's, 're, 'm, são as contratações de
He is, she is, it is, you are, we are, they are e I am.

Veja:

I'm student (I am student)
You're tall (you are tall)
He's my friend (he is my friend)
She's beautiful (she is beautiful)
It's cold (it is cold)
They're playing (they are playing)
We're happy (we are happy)

Obs: não confunda WE'RE com WERE.

IT'S com ITS.

Os significados em português são :
É, ESTÁ ou SÃO.

No caso genitivo o apóstrofo seguido de s ('s) tem significado de posse. Mas isso é outra coisa.
