In 1968, Nauru became one of the richest countries in the world. Every year the government received millions and millions of dollars for its phosphate. Unfortunately, the leaders invested the money unwisely and lost millions of dollars. In addition, they used millions more dollars for personal expenses.

Dear Mr Headmaster, Task Seven:Conclusion.----Enjoy the possible version. ： I’m Li Yue, a student from Class 1, Senior II. I would like to bring it to your attention that recently,some students have been scribbling and littering at random, making us feel concerned about our campus environment. . Such bad behavior as scribbling hurts our school’s image as many people come here to watch matches or attend other sporting events. What’s worse, the litter on the ground makes it hard for people to enjoy relaxing. which should otherwise be picked up by everyone. It’s really terrible to see that by the time we students leave school, the rubbish has been everywhere. As is known to all, rubbish should be left where it is supposed to be and the campus will be more beautiful with clean grounds. I suggest the school make an announcement restating that scribbling on walls and littering are not acceptable.In addition, it is also a good idea to add more waste bins to the ground area.I believe that, with the joint efforts of both teachers and students, our school will become a more enjoyable place in the near future. Thank you for your consideration.
