This is a good free newspaper website - it is free for us in the UK

Also the BBC website has lots of information for adults and for children.

BBC bitesize is lessons for children, CBBC is for children and CBeebies is for small children.
You can search to find them. I mention the children's part as the vocabulary is different for children - sometimes simpler but also sometimes more natural.
