When it comes to mathematics, reading and science, young people in Shanghai are the best in the world, according to a global education survey released Tuesday.

根据周二发布的一项全球教育调查结果显示，上海学生在数学、阅读和科学等学科上的学习能力是全世界的。

In all three subjects, Shanghai students demonstrated knowledge and skills equivalent to at least one additional year of schooling than their peers in countries like the United States, Germany and the United Kingdom.

在上述三个学科中，上海学生的知识和技能比美国、德国和英国的同龄学生高出至少一学年的水平。

The findings are part of the 2012 Program for International Student Assessment (or PISA) -- a leading survey of education systems conducted every three years by the Paris-based Organization for Economic Cooperation and Development (OECD), a grouping of the world's richest economies.

这一调查结果来自于2012年的国际学生评估项目PISA——国际学生评估项目是一个由经济合作与发展组织筹划的针对学生学习水平的测试计划，本部位于巴黎，每三年进行一次，是目前世界上影响力的国际学生学习评价项目之一。

More than half a million students, aged 15 and 16, sat a two-hour exam last year as part of the study. The pupils came from 65 countries representing 80% of the global economy.

去年，超过50万年龄在15-16岁之间的学生参与了一项两小时的测验，测验结果成为国际学生评估项目测评的依据。这50万名学生来自全球65个国家（地区），代表了全球80%的经济体。

East Asian economies performed best overall, claiming seven of the top 10 places across all three subjects.

总体而言，东亚国家的学生成绩，三门学科成绩的十个国家中有七个是东亚国家。

In math, Shanghai had the highest score with 613 points -- the equivalent of nearly three years of schooling above the average for the 34 OECD member countries of 494, and six years above Peru which ranked last with a score of 368. The city also came top in 2009 rankings.

上海学生的数学平均成绩为613分，经济合作与发展组织的34个成员国学生的数学平均成绩为494分、比前者低出近三学年的学习水平；秘鲁学生的数学平均成绩为368分居末位，比上海低出六个学年的学习水平。在2009年的国际学生评估项目排名中，秘鲁曾居。

Singapore came second in mathematics with a score of 573, followed by Hong Kong, South Korea, and Macau.

新加坡以573分的数学平均成绩居排名第二位，其后是香港地区、韩国和澳门地区。

But the math performance of most countries has not improved since the PISA tests were launched more than a decade ago. Around 60% of the 64 countries who participated in previous studies performed at the same level or worse in 2012.

自国际学生评估项目十余年前创立以来，大多数国家学生的数学平均成绩并没有提高。64个受调查国家中有60%的国家数学平均成绩与2012年持平或比2012年更低。
