Win a week in England!

You still don’t know what to do this summer? Well, here’s your chance to win a one-week language course in Kent, England! Free4Fun and ETC (English Travel Connections) are giving  away two trips to Rochester. This historic city is less than an hour’s drive from London and close  to the sea resort of Herne Bay. It is also the home of one of England’s most famous writers,  Charles Dickens. The town of Rochester is in Southeast England. Charles Dickens often wrote  about it in his books. His home, Gad’s Hill, is there, too. A popular attraction is Rochester Castle, a large Norman fortress（堡垒）. It was built in the 11th century and rebuilt during the 14th century. Other attractions are Rochester Cathedral, which was built during the 13th century, and Dickens Centre. It has got its name in honour of Dickens himself.

The trip to England includes:

*  travel by train (via the Eurotunnel) to and from any railway station in Germany

*  room and full board with a guest family for one week

*  language course in small groups

*  two trips to London

*  large choice of sports and entertainment

*  German-speaking advisors available 24 hours a day
