Dear President of the Student Union,
I am Li Hua, a student from Class 1, Senior Grade 1. I am writing to propose organizing a "Campus Safety Week". Having learned about natural disasters , I strongly believe it is vital to raise awareness and take precautions .
First and foremost, it is advisable to invite experts to give lectures on how disasters occur and how to prevent severe damage . Additionally, we could design posters about preparing an emergency kit , which is essential for survival . Last but not least, remember to organize a practice drill so that everyone knows how to evacuate calmly and safely.By taking these measures, we can minimize the impact of potential emergencies and create a safer campus.
I sincerely hope you will find my proposals useful. Thank you for your time and consideration.
Yours sincerely,
Li Hua
