Task 2：Independent Writing
A city wants to help teachers of its high school students (age14-18) improve their teaching. It is considering two plans:
1. Choose a small group of excellent teachers; these teachers will attend a class led by an expert for additional training in how to teach effectively, and they will then come back to their schools and provide that training for other teachers in school.
2. Provide additional training in teaching effectively for high school teachers, using online material that each teacher will study individually.
