Dear President, I hope you are doing great! (This is too informal for writing to a president) I am LiMing, a senior student at our university. I'm writing to you to make some suggestions about how the students' physical condition can be improved. Firstly, nutrition is of key importance to health. However, the dishes provided by our school are usually oily and bad-tasting which has resulted in numerous students frequently ordering delicious but unhealthy takeouts. Therefore, could you advise the canteens to improve the taste of their foodvand diversify the dishes. In addition, to motivate more students to engage in exercise, more sports activities could be organized, such as weekly night running. As well as this, giving yearly physical examinations is a good way to check whether students are in a healthy physical condition and to highlight any potential dangers. Hopefully, you will take my suggestions into consideration. I really appreciate your time and attention. Kind regards, LiMing

Dear Mr. President (or "Madame President", or "President Jones"): I hope you are doing great! I am Li Ming, a senior student at this university. My purpose in writing this is to offer suggestions how the physical condition of students might be improved. Firstly, nutrition is of key importance to health. However, the oily and bad-tasting dishes available to us frequently cause students to seek out substitutes in delicious but unhealthy takeout foods. I suggest that the canteens increase both the appeal and diversity of their dishes. In addition, I suggest an effort to motivate more students to engage in physical exercise by organizing more sports activities, such as a weekly running night. As well, encouraging a yearly physical examination would be a good way to check on health and reveal incipient problems . I do hope you will take my suggestions into consideration. I deeply appreciate your time and attention. Sincerely, ("regards" is informal) Li Ming
