　　What Makes a Good University

　　Everyone is cautious about choosing a good university to receive higher education because studying at a good university may be a turning point in your life and bring you a brilliant career in the future. But do you have a clear idea about what a good university is?

　　In my opinion, there are some critical factors contributing to a good university. First of all, the vital one lies in the motto and mission of a university. As Yale University’s mission is to train for public service, a good motto or mission lets a university and its students be able to reach something tangible and leads them to the way to success. Secondly, academic atmosphere is of great importance as well. A good university should have a great academic atmosphere so that its students are enthusiastic to involve themselves in a group brainstorming and learn from each other. What’s more, it’s also absolutely necessary to have excellent teaching staff and facilities. Learned tutors can give a had to smooth students’ road to success and students can take part in various interesting extracurricular activities with the help of well-equipped facilities. Only in this way can they achieve their well-rounded development.
