The Plan with the Exchange Students
 
The exchange students are going to visit our school. I would like to give them some suggestions. Firstly, I will introduce the history and culture of our school to them. They can help them know more about our school. Secondly, we will have a lesson together. In the class, students need to work in groups so that we can communicate ideas with each other. I think we can learn a lot from team work. Thirdly, we will hold a science competition. It is helpful for us to improve our knowledge and skills. Finally. we will have a friendly sports activity. They can know more about our school.
  All in all, I hope that the visit of exchange students will be successful.
