We have discussed so far a variety of issues. What you need to do is to look at these issues and choose one that interests you the most. Then go to either China Post or Taipei times and read/choose a related news item that was published on their paper.
Compose your letter to the editor following the guidelines I gave, and send your letter to the editor via email (see links below). When you send your letter (to the Editor) do not include your student number nor indicate that it is an assignment. You need to present your work as a letter coming from a concerned Taiwanese citizen who has something relevant to say/comment on.
Before you compose your letter, study the already published letters, and analyze their format. Follow the same writing format and style.

You will be notified by the editor if your work has been chosen. If it was, please do not forget to inform the class about it.
