For example:
Hello, seniors and sisters, my name is XXX, and I come from XXX College, majoring in XXX. I usually like reading and writing. First of all, I am cheerful and easy-going, with strong expressive ability, and I can make things orderly. I am also resourceful and conscientious. I used to be a monitor in high school, and I was able to finish the tasks assigned by the teacher efficiently and rigorously without procrastination.
I want to join the student union because I want to exercise myself and make many friends through the student union. I think the original intention of the student union is to help students, which makes me more determined to join the student union. Moreover, students will have many voluntary activities, from which I will learn a lot and help more people.
If I am lucky enough to join the student union, I will work hard, be proactive, unite as one, help those in need, finish all the work assigned to me on time, contribute my own strength to the construction and work of the student union and give full play to my due role.
I know I still have many shortcomings, but I want to exercise myself, improve myself and improve myself from here. If my senior can give me a chance, I will not live up to my expectations! Thank you, senior and senior!
