　　A global university, considered as absorbing foreign students and faculty, cooperating with foreign universities and facing a highly globalized view, is recently being accepted and desired by more and more countries, since it can concentrate the world's most talent intellectuals, so as to gain different perspectives and successful experiences. On the other hand, nowadays world is facing diversified social problems,including poverty, economical reform, terrorism, multi-media globalization,environmental problems and so forth, many of which are interacted between elements separated in different nations, therefore asking for a global sight to analyze and solve.In these senses, I think it will serve many nations' interests to develop a global university to engage students in the process of solving the world's most persistent social problems.

　　Universities are born to provide nation elite in evey field of it. From ancient Greek forums to nowadays world-top universities, these campuses have never lacked of young students who are eager for knowledge and ideals, as well as experienced and erudite teachers. In both teaching and researching aspects, modern universities are playing an important role propelling the world's development. Consider these facts:the first computer which had then changed the world was made in University of Pennsylvania; a myriad scientists who won Nobel Prize came from Princeton University; many of current leaders of China graduated from the nation's most famous university, Tsinghua University; the architecture department of Delft University,which locates in Amsterdam, has provided not only the Netherlands but also the whole world a number of van ward and creative architecture masters. It is these universities' feat that has solved many social problems, changed the world dramatically and supported it by their graduates or undergraduates.

　　Realizing the important function of universities, establishing a global one seems more effective in solving the world's most difficult social problems, which ask for a myriad efforts and most intelligent talent, in the following three points.

　　Firstly, a global university which gains students from different nations, different cultural backgrounds and different education systems can therefore contain diversified views, methods and perspectives when dealing with a social problem. Students in different countries are taught in their unique basic education systems, and they are influenced by the society and their traditional culture separately. New views can be brought to a global universitiy by those who have never been to its nation, making its thoughts more creative. For instance, as an American university student, IM. Pei, who was born in China and entered the countries far away from his motherland, won his first competition, the Monument of Vienam War. This monument was considered as a very important issue to show Americans' views to that cruel and tragedy war. IM. Pei used a different way to create a knife like shape into the site and made the monument full of symbols. After his graduation, IM Pei has then managed many global projects.Undoubtedly, a multi educating background gave him the ability to face architecture in different nations. As the students receive such diversified creative methods, the society will benefit a lot from a global university, which seems to be bidirectional.

　　Secondly, a global university itself can be a solvent for many social problems, such as racism, war and national abhorrence. Students in universities will likely become the nations' leaders after their graduation, since they are most educated and intellectual. In a global university, elite from different countries, with different skin colors will get together. They get in touch with each other, understand others' thoughts, religions and learn about tolerance, communication and so forth. Because of such communications with foreigners, global students will come out of campuses of global universities, bringing a global world for peace, tolerance and understand.

　　Thirdly, from developing a global university, a country's education system can absorb successful experience from other countries during its reforming progress. Universities in different countries have different researching, teaching and managing methods.Some are reasonable, while others are not. By learning from international students and teachers, an university can understand the world's most advanced teaching methods,managing structure and so forth. China has understood this, therefore making its Peking and TsinghuaUniversity more globalized, by inviting professors from other nations, encouraging international enrollment and learning from American top universities. Professors and students from Princeton, MIT, UPEN, Delft, Oxford and many other world top universities join in their projects and forums, therefore providing these universities vitalized development. Such projects and forums are many focused on environmental problems, poverty, urban renovation and other social problems, having solved many persistent ones.

　　To sum up, a global university can be effective when dealing with the world's most persistent social problems, considering about its mentioned advantages. Although languages, resources and policies may play as obstacles during a global university’s establishment, I believe all nations need a global university or even more for its further development, because the world's social problems need the whole world to face, especially for those who have made themselves branch into this uniformed system.
