But at the same time,the opening of national borders to the flow of goods,services,information and especially people,has made universities a powerful force for global integration, mutual understanding an geopolitical stability.
【正确答案】：国家对于商品、服务、信息，特别是人才的开放，使大学成为促进全球一体化、相互理解和地缘政治稳定的强大力量。【解析】原句是主谓宾结构的简单句，主语是the opening of national borders，谓语是has made，宾语是universities，a powerful force是宾语补足语。汉译时将定语to the flow of goods. services，information and especially people 提前，增译“促进”，or global integration,mutual understanding and geopolitical stability也提前，作“强大力量”的定语。
