What is the best way to write a 50 word answer. What things do I need to take into account?

1. Include different tenses
   This is not as difficult if you think that you can include 3 or 4 tenses in a paragraph of 4 sentences. Fore example:
   
   I love dancing and I have danced for many years (present and perfect). When I was a child, I used to have dancing lessons every week and in my teens I danced every night (imperfect and preterite) and I enjoyed every minute of it. When I am an adult I will dance for a living and I would love to be part of a dancing company (subjunctive, future and conditional) ¡Que guay!
   
   
2. Include connectives to make sentences longer and more interesting
   
   
3. Always include opinions and ejaculations

I also have exemplar paragraphs to look through with students.
