Salut, voila j'ai un devoir en anglais et je n'y comprend rien, de l'aide svp ? 

Texte : I'm writing to you from school, sitting in front of the laptop I use in class. I'm waiting for my history class to start. We have wi-fi here so it's really easy to send e-mails and surf the net. How often do you use computers at school, and do they all have Internet access ? 
My class starts at 9 a.m. and the teacher is always complaining and saying we are late?!
Oops, she's walking in the hallway. Talk to you soon, bye !

1) Look at the auxiliaries.
Identify and explain the 'm, 's ans is. Which auxilary is it? 
Find the other auxiliary in the text and explain when each auxiliary is used.

Look at the sentence :  We have wi-fi. 
Is "Have" an auxiliary or a verb here ? Explain the difference.
