Thank you for using the Jiskha Homework Help Forum. Simplify what you are saying, using the structures you have studied and the vocabulary. First of all, you need to pick a subject, so try to pick one with the current vocabulary you are studying.
Any newspaper will give you basic ideas. There are many Spanish-speaking newspapers as well out there, which I'll be happy to supply for you, if you would like. Any Spanish-speaking country will have a "Reuters" column.
There are also Weather sites for any country as well.
