　　帮你找了一篇，但由于你弟弟是小学生，我做了很多改动，看上去更真实

hello, everyone, i’m very glad to stand here and introduce myself to you, i come from （你弟弟的学校）. my chinese name is （你弟弟的中文名） and my english name is （他的英文名）. do you know why i'm always smiling?because i want to show my happiness and bring my happiness to all the people forever.
i have two dreams, the first one is in the future if i have enough money, i’ll first set up some hope primary school, because there are still some children who can’t go to school to study. the other dream is that one day i could travel around the world. in my opinion, travelling is the most exciting thing.

in my opinion, everything in the world is wonderful, especially my lovely school.
my school is called (他的学校）. it has a long history and there are about 300 teachers and about 6000 students in it.
my school is a very good school. so everything here is excellent. we have a lot of modern equipments which can do good to our teaching. every week, we will have several classes in the multimedia classrooms. in this way, we can improve our study.
we have six classes every day. the first class begins at 8:00 am. i like all the classes, because my teachers can make the classes lively and interesting. my favorite subject is english. i speak english with my classmates every day. i think it’s helpful for me to learn english well. after class, i always play games with my friends. we play basketball, ping-pong and so on. they are relaxing. i like my lessons, my friends and my teachers. in a word, i love my school, my school life is wonderful.
when i first went into the school gate and saw my new classroom and teachers i thought i would have a new beginning. there are many activitese in our school, such as sports meeting, science week and art week. we all take an active part in them. our teachers have taught us a lot. they not only teach us how to study but also teach us how to be a useful person in society. they tell us anything that is worth doing and habit is a second nature. so teachers often remind us to make a good habit.
our school is clean and beautiful. there are many trees and flowers around it, especially in spring. in order to make our school more and more beautiful we should try our best to keep it clean. our students won’t throw rubbish on the ground, because we are members of it.
i love my lovely school. i hope everyone here will like it ,too. today, i want to say: “i bless you a brighter future, i’ll support you forever—my lovely school”.

that's all.thank you.
