when i was 6 year old i used to play football

you were so happy yesterday!

it was kind of you to help me with my homework

he was the best tennis player i have ever met

she was very beautiful so i fell in love

we were lucky to win 1000000 dollars

you were here last sunday - i know certainly!

they were not here because they were working all day long

i like watching a films. and my favourite film is " avatar", directed by james cameron.

to tell the truth, i have not seen anything more interesting and exciting in my life.the   film descibes the events of the year 2154.the story it advances the idea of care   for living beings and the nature as the only way to survive for the whole planet. it shows how cruel people may be. so everyone can make parallels to the ecological situation on the earth and the way people treat it.

to my point of view? this film is great!
