总体上感觉不错.
祝学习进步!

Dear Jack,
I am so glad【比how nice书面化一些】 to hear from you again. Since you want to know what is going on in our school, let me tell you something interesting【一点改动】.
Quite a few changes have taken place in my school recently. In the past, the teachers【改为复数】 always kept on explaining the points in class. Students just took notes. But now, we often discuss and try to solve the problems rose【rose改为raised】 by the teachers【改为复数】 or ourselves. After class, instead of doing so much homework, we enjoy【改为一般现在时】 different kinds of activities. We can read what we are interested in and study what appeals to us, such as computer. We can also go to the library or surf the Internet for various kinds of information.
We enjoy ourselves at school.
Best wishes
Yours
Li Ming
