Ladies and gentlemen, I"m very glad to welcome you to our Language School where we hope you will enjoy your stay. Getting used to new faces and finding your way around the building will take a little time but you should soon be able to settle down to the job of improving your English. Nowadays most people would agree that speaking a language is the most effective way of learning it pleasantly and effectively. You will find your teachers using English throughout your course. You can rely on your teachers being patient and understanding because all of us here realize that learning in an adult group is very different from learning alone or in a secondary school. The intensive practice we offer in this short course will involve your talking with your teachers and classmates in English, and will mean your participating actively in order to learn and to help others to learn.
We have very few rules at the school but I hope you will not mind my mentioning one or two fight away. We prefer no smoking in class unless your classmates agree otherwise. We advise no talking in your own language even if you meet a fellow countryman in the school. We recommend you keeping the lecture rooms tidy because studying in pleasant surroundings is less tiring, therefore please use the wastebaskets provided. We encourage you to borrow books from the library but please remember to return them on time.
We hope you will learn a good deal of English and enjoy yourselves in London.
