Do you know a new educational CD-ROM called Around the World in Eight Hours has just come out ? It sounds interesting. It can help you learn English and geography at the same time. It helps you learn English by testing your knowledge of English grammar and vocabulary. It is designed by Nancy Jackson who is also the designer of Online Traveller.
