Answer 1

a) she's young

b) they're lazy boys

c) you're my friend

d) he's my boyfriend

e) you're very lucky

f) I'm a secretary

Sujeito + verbo to be contraídos, vão ficar assim:

I'm = I am  

He is = He's

She is = She's

You are = You're

We are = We're  

They are = They're

Answer 2

a. She's young.

b. They're lazy boys.

c. You're my friend.

d. He's my boyfriend.

e. You're very lucky!

f. I'm a secretary!

Lembrando que your e you're são homófonos, assim como they're, their e there, e he's e his.
