Now imagine that you are Alexander Fleming. You have just discovered penicillin and you are very excited about the new chemical. Write a letter to a famous medical journal to tell about your discovery. Tell them what you have discovered and what it can be used for. You may use the information in the box to write a letter. Penicillin
Is a natural mould that is easy to grow and use Will make hospitals safer Can cure infections Kill bacteria Can be used to treat diseases

Sample writing: Up to now, people are still suffering from the incurable infections. However, such these days ends because a natural mould has been discovered, that is penicillin.

The discovery was a matter of luck really. One day, when I was washing the glass containers for growing bacteria, I found a mould was growing in one of jars and the bacteria around the mould had died and stopped growing. I realized it was the chemical which could treat infections, and I called it penicillin. After that, I made experiments to make it work better. Penicillin has many strengths. First of all, it is a natural mould that is easy to grow. What’s more, it can cure infections by killing bacteria, so it can be used to treat diseases. If we put penicillin to use, our hospitals will be safer and our treatments more effective, reducing the pain of patients in hospitals. The people all over the world will benefit from it greatly I hope you can help introduce penicillin to the public. As the chemical is more widely used, patients will get a better treatment, people will live more happily. Our world will be more harmonious. VIII. Homework 1. Please write a short passage to describe the discovery of penicillin in

Fleming’s voice. 2. Please read the passage Angels In White at Page213 and finish the exercises to match with it.
