以我们在美国国家艺术和科学院引领的五年计划为基础，我们相信UPE目标还不够雄伟：全世界应该，也能够，像普及全球初等教育一样普及全球中等教育。
Based on a five-year project that we led at the American Academy of Arts and Sciences, we believe that the UPE goal is not ambitious enough: the world should aim for, and can achieve, high-quality, universal secondary education, as well as universal primary education.
