Dear David,

   I’m now learning English by myself . Can you introduce some useful websites where I can make friends with foreigners ? Please help me.

  David writes: Well, dear moonlight , I bet you will make a good choice by using the Internet in your studies. Two very good websites I would suggest to you are: www. British council. org. cn and www.britishcouncil. Org. cn /learn English.

  And also, a healthy warning to all my readers : If over used, the Internet can be a WOMBAT----a Waste of money , Brains and Time!
