One possible version：

Dear friends， 

We all know the old saying：

“All work and no play makes Jack a dull boy.”That’s why I’d like to share my opinions about how to reduce pressure from our study. 

①First, we need enough sleep at night because staying up too late is bad for our health. Second, we must take some sports as sports activities help build a strong body for us to face our daily study. ②In addition, we may have our parents plan an occasional short holiday since a holiday is a welcome relief from the pressure of work. Only when we are healthy and energetic can we become prepared for any hard task in our schoolwork and get fruitful results.

                                                               Sincerely，

                                                          Li Hua

【一句多译】

①To begin with, we need enough sleep at night in that staying up too late has a bad effect on our health.

②Last but not least, we are supposed to let our parents arrange an occasional short holiday which can give us a welcome relief from the pressure of work.
