Attention please!

I’ve something to tell you. Professor Jackson―an English disabled person will come to our school to give us a lecture from 2 to 4 o’clock on the afternoon of April 25 in Room 302, the No. 3 teaching building. His lecture is about how he smoothed away all sorts of difficulties. When he was eight years old, he lost his left leg and right arm in an accident. He struggled in his life and managed to look after himself. He achieved great success in his work, too.

After the lecture we will have a discussion in groups on how to encourage disabled people, how to help them and how to learn from Professor Jackson.

Thank you!

Li Ming
