假如你是李华,在英国剑桥大学学习,请根据内容要点和要求,给你的英国朋友Tom写

Dear Tom ,
It was great to hear from you again . There are many things going on in our school . In fact things have got much better since we started a different way of learning .
In the past our teachers stood in front of the class talking all the time while we students listened , busily taking notes . After a tiring day at school , we always had a lot of homework to do . Sometimes we even worked late into the night . Now we are active in class . We often have discussions in pairs or in groups . After class we enjoy all kinds of activities , such as going in for sports , dong experiments or surfing the Internet.
We are extremely happy about the changes in our studies .
All the best ,
Yours ,
