Dear schoolmates, First of all, let's give our warmest
welcome to our honourable guest --- Mr Luois Alexander. Mr
Luois Alexander is a world-famous English linguist. He's
written lots of works, including New Concept English, Follow
Me and so on. All these are well known to us all. Mr Alexander
is invited to Chongqing to give lectures, and today he's going
to have a talk with us to get a further understanding of
English study in middle schools in China. If you have any
questions on English, you are free to ask him for help. Now
let's invited Mr Alexander to give us a talk and advice on
English study. That's all. Thank you!
