An Open Letter

Dear Schoolmates,

The Students' Union is engaged in planning some activities to help improve unproductive tendencies among the students, with the worst of them all being the excessive consumption of resources. The purpose of this open letter is to bring this to your attention and to advocate for the habit of being thrifty in all of your activities while on campus.

Being economical is a traditional and time-honored virtue of Chinese culture, but today many of us seem to have forgotten that. Excessive consumption has become a serious issue within our college: water, food, and even time, are not properly valued and cherished. Such behavior is not only disrespectful to the hard work of others, but it also shows a proper lack of appreciation for their efforts on our behalf. So, please join us in fighting against waste and in practicing thrift since every effort--no matter how small--helps in this goal.

We truly look forward to your participation.

The Students' Union

Hi Dandan. Good job! Whatever changes that I’ve made were merely done to allow your sentences to sound more natural to my native ears. I hope that this helps you. J.

P.S. Your handwriting is fine!  P.P.S There is no grammar rule for not starting a sentence with "And" or "So" or any other conjunction. 

Open letter

Dear schoolmates,

The Students' Union is planning some activities to improve the unhealthy tendencies in our college, and we think waste is the worst of all. This open letter is for the purpose of advocating thrift.

Economy is a traditional virtue of the Chinese nation, but today many of us forget that. Waste has become a terrible state of the college: Our college has become very wasteful: water, food and even time are not cherished. It's not only waste, but is also disrespectful to the work of others. So We'd better refuse waste and start practicing thrift!
Please consider our sincere suggestion, and we look forward to your actions!

Sincerely,

Your Students' Union

Nice job. The letter was very good, I just changed a few grammar things. Saying " for the purpose of advocating thrift" sounds strange to me, but its not wrong. (maybe because I'm American, it sounds British to me)  Remember, never begin a sentence with and or so. Remember to put a space between a period and the next letter. The handwriting looks good.
