Thanks 4the help Mr.Jlinger

I have another doubt (sorry but is homework so maybe i will have several questions more)

to correct way is to say used to OR use to?

[jlinger]

I am used to your face now.
It took some getting used to, but I did it.
I used to think I could only love a beautiful woman.
There is no use to argue about it.
I'll get a bucket. That's something I can use to cover your head.

Well, that's his homework done.
What has he learnt?
Why is, "The moon moves around the Earth every 28 days" correct and not, "The moon is moving around the earth every 28 days"?

Pity the English teacher who gets a shock after a closed book exam that the standard of English of one of her pupils is not what his homework has indicated.

OK, give the right answers...but explain why!
