My topic today is the Internet. It was prompted(引出)by the first letter, which I am unable to answer fully for the reasons given!
Dear David,
I’m a middle school student. Now I am preparing for a writing petition. Could you please check the mistakes in my article about using the Internet and
Give me some advice?                           No name                                                                               David writes: I’m very sorry to say that I think it would be very unfair for me to help you win a petition--- unfair to the other petitors!
But I’ll say that your article is very interesting and I wish you good luck.
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 think you made a good choice by using the Net in your self-studies. Two very good websites I’d suggest to you are:
www.britishcouncil.org.cn and www.britishcouncil.org.cn/learn.
By the way, for those readers interested in the teaching of English, there is an Internet discussion group called ELTCSChi-L (English Language Teaching Contacts Scheme China List).
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!
