Good evening ,ladies and gentleman
Many years of waiting,many years of holding on,finally,some lucky dogs rushed out of the high school gate and entered the enchanting university.There ,they will meet lots of new people,stopping being a child and becoming an adult.They will certainly open a new chapter of their life.When I was a freshman here,I found that I was so luky that I have choosen the best major in our university.But one of my best friends from the same high school was so sad that he was told his major is not very good.Then,after one year studing time,his sadness has disappeared.He told me that now he loves his major so much,actually ,there is no best major,all of the majors in our university are very important and useful for the society,every sigle department needs persons with ability.And I think that is exactly the unity and diversity.
