A new way to learn English This week, we've interviewed Yusuf Massri in Year 11.

Yusuf has never scored under eight or nine points in an English test and his spoken English is amazing. But he hasn't had extra English classes at school and he hasn't read an English dictionary! So how has Yusuf become so good at English? He says that his secret is Whyville - an online world for young people, which was started in 1999.

Whyville is a virtual world in English for teenagers from around the world. It is very popular and has more than seven million users. You don't need to spend any money because the website is free. Players have an avatar (a character in a computer game). The avatar lives and works in an invented 'virtual' world. The avatars can go shopping and spend money - 'clams' - in the shops. They can also play games, learn about science or maths, eat, dance, travel and even go to pop concerts.

How has Whyville helped Yusuf to improve his English? Well, there are different places in Whyville where you can practise your English,' explains Yusuf. 'There are a lot of games and competitions in English. There is also a special newspaper called The Whyville Times, which comes out every Sunday. I use this to practise reading in English and I've written an article for it too.

'On Whyville you can take part in online book discussions. I'm not obsessive, but I've enjoyed chatting to other teenagers about my favourite stories. I never feel isolated at home now because I'm part of an online group of people. I've made friends with players from seven other countries and we always chat in English.

Complete the sentences with one word from the web page. 1. Yusuf always does well in an English ....

2. Yusuf goes... to play Whyville.

3. Everybody on Whyville has their own.... 4. Players use money called 'clams' when they go to the....

5. Yusuf doesn't feel... when he is on Whyville.

6. Yusuf has friends in ... different countries.
