I need help for my homeworks :D

Hi people!

I'm Giovanni and I'm italian.

I need help for my english homeworks for tomorrow. It's a letter to describe Italian TV Channels. I already wrote it. I need just a correction.

Thanks to all.

Here it:

Dear giorgia,
how are you? I'm fine. In your last letter you spoke about David letterman's show, it's too funny!
Here in Italy on TV there are a lot of channels since there is the terrestrial digital in all the
region, but the main channels are rai 1, rai 2, rai 3, rete 4, canale 5, italia 1, la 7. My
favorite channels are channel 5 and italy 1 of Mediaset.
On Italy 1 show documentaries, serials, films, quizzes, comedy series, talk shows, news bullettins
and cartoons for children and on Channel 5 there is the same.
My favorite shows are Zelig and Colorado. They are comedy shows very funny! There are *
I watch every day the news bullettin to stay informed, at lunch and at supper, and every evening,
especially on saturday, i watch a film. Instead you? I like action films and adventure movies. I
know that you love thrillers! Few days ago on channel 5 showed Sherlock Holmes, a good film.
Now I must go to my grandma's house because she called me and she said me that lasagne are almost
ready: i love lasagne!
Write soon,
love,

                                                Giovanni

* here I must write that There are comedian very talented (comedian = people funny on TV...I think)
