你是李明，給校長寫信，說明學校食堂質(zhì)量問題

A letter to the university president about the canteen service on campus

Mr. President:

   I am a junior in our university majoring in Mechanical Engineering. First of all,      I am relly sorry to trouble you, but it is canteen service that indeed bothers me.     So I wrote this letter delivering some personal comments and suggestions.

   The quality of some cuisines needs to be improved. Everyday, with great expectation, entering into the canteen, we require wondful food. But is turns out   to be a dream that never takes wings. Sometimes too salty, sometimes too spicy.  When winter comes, the food goes cold if we arrive a little late. Apart from the quality, the price is supposed to be adjusted, too. Some food which is fragrant  and delicious has been  priced dramatically high that most of us can't afford.      We are just wondering it is for dinner or for appreciation. From bad to worse, the lights  are so somber that we had to grope the door knob in the dark for several times. Such environment makes our appetites depressed.

   To sum up, the service in canteen is expected to be boosted and the qualifications of public servants need to be trained as well. Customers  are   always right. We deserve terrific quality. So, your excellency, I , on behalf of my classmates, will be  appreciated from the bottom of our hearts if you will take actions immediately.

                                  Yours respectfully
