2.we go back to class at 11 .Sometimes we have to saty (stay) in school in the evening for practical classes. I am not sure about these two sentences. Do you mean you go back at 11.00am or 11.00pm? If the former, then this means that you go to school (at some unspecified time in the morning), then leave, then go back at 11.00am, then stay until the evening. If the latter, then it means you go to school for some unspecified time during the day, then go back at 11.00pm and stay for some unspecified time for night classes, which would have you staying in school until after midnight. This would not be considered 'evening'. I really don't understand what you are saying here.

4. He is a famour football player for the Spanish team. Or, he plays football for Spain.
