Letter of suggestion for improve

Dear principal ,

  I'd like to give you some advice about our school.

  First of all , our classroom , which will be hot in summer , needs to install some air conditioners so that we can study better. Besides , I hope the dining hall can provide some healthy and delicious food for us , because we are teenagers now and we need to grow healthily. What's more , I hope you can build more and more basketball courts , because it will allow students to have more time and more places to play sports.

  In the end , I hope our library can provide some books about study for us.It is good for us to learn a lot from these books. Also, we can build a biological garden , which can make us watch the nature closely.

  I hope you can take my advice and make our school better and better.

Best wishes.

Yours,

sb.
