1 I would suggest that you must tell the workers to clean up the beaches.
2. I am writing to you because the beaches in our city are extremely dirty.
3. They were full of litter, waste and dog dung when I went there last week.
4. They smelled unpleasant, at that time tourist an I were annoyed.
5. They are still in a mess this week.
6. I am looking forward to receiving a good response from you.
