The only problem they can have, is maybe that they'll find some articles a little bit difficult, that's why I recommend Simple English reading where they understand 90% of the global reading.
This method helps a lot to improve your English vocabulary, for example you will have a huge vocabulary about cars if you're interested in cars. I also recommend images to help you even more, they help you to understand a lot of things you can't understand using dictionaries, (Actually, there are many dictionaries with images nowadays)
well, it's only a short article today. I recommend that you read my article about Simple English Reading.
