Good morning, class.
早上好，同学们。
My topic today is how to feed a hungry world.
我今天的主题是如何养活一个饥饿的世界。
The world's population is expected to grow from 6.8 billion today to 9.1 billion by 2050. Meanwhile, the world's population more than doubled from 3 billion between 1961 and 2007. Simultaneously, food production has been constrained by a lack of scientific research. Still, the task of feeding the world's population in 2050 seems easily possible. What is needed is a second green revolution. This is an approach that is described as the sustainable growth of global agriculture. Such a revolution will require a wholesale shift of priorities in agricultural research.
预计到2050年，世界人口将从今天的68亿增长到91亿。与此同时，世界人口在1961年至2007年间从30亿翻了一番多。同时，由于科学研究不足，粮食生产一直受到限制。尽管如此，到2050年养活世界人口的任务似乎仍然有可能实现。我们需要的是第二次绿色革命。这是一种被描述为全球农业可持续发展的方法。这样的革命将需要农业研究重点的全面转变。
There is an urgent need for new crop varieties. They must offer higher yields but use less water, nitrogen-rich fertilizers, or other inputs. These new crops must also be more resistant to drought, heat, and pests. Equally crucial is lower-tech research into basics such as crop rotation and mixed farming of animals and plants on small farms.
我们迫切需要新的作物品种。这些作物必须产量更高，但使用的水、富含氮的肥料或其他投入更少。这些新作物还必须更耐旱、耐热和病虫害。同样重要的是，对诸如轮作和在小型农场上动植物混合种植等基础技术的低技术研究。
Developing nations could score substantial gains in productivity by making better use of modern technologies and practices, but that requires money. It is estimated that to meet the 2050 challenge, investment must double to $83 billion a year. Most of that money needs to go towards improving agricultural infrastructure. Everything from production to storage and processing must improve.
发展中国家可以通过更好地利用现代技术和实践，在生产率上取得巨大进步，但这需要资金。据估计，为了应对2050年的挑战，投资必须翻一番，达到每年830亿美元。其中大部分资金需要用于改善农业基础设施。从生产到储存和加工的一切都必须改进。
However, research agendas need to be focused on the needs of the poorest and most resource-limited countries. It is there that most of the world's population lives, and it is there that population growth over the next decades will be the greatest.
然而，研究议程需要关注最贫穷和资源最有限的国家的需求。世界上大多数人口都生活在那里，未来几十年那里的人口增长也将最大。
To their credit, the world's agricultural scientists are embracing such a broad view. In March, for example, they came together at the first Global Conference on Agricultural Research to begin working out how to change research agendas to help meet the needs of farmers in poorer nations. But these plans will not bear fruit unless they get considerably more support from policymakers.
值得称赞的是，世界农业科学家正在接受这种广泛的观点。例如，今年3月，他们齐聚首届全球农业研究大会，开始研究如何改变研究议程，以满足贫困国家农民的需求。但这些计划除非得到政策制定者的更多支持，否则不会结出果实。
The growth and public agricultural research spending peaked in the 1970s and has been shrinking ever since. The big exception is China, where spending has far surpassed other countries over the past decade. China seems set to transition to become the key supplier of relevant science and technology to poorer countries. But developed countries have a humanitarian responsibility to cause large increases in the appropriation of funds for public spending on agricultural research. These are more than justified.
公共农业研究支出的增长在20世纪70年代达到顶峰，此后一直在下降。中国是一个例外，过去十年来，中国的支出远远超过了其他国家。中国似乎注定要成为向贫困国家提供相关科学和技术的主要供应国。但发达国家有责任为公共农业研究支出大幅增加拨款，这是完全合理的。
Questions 22 to 25 are based on the recording you have just heard.
问题22到25是基于你刚刚听到的录音。
Question 22: What is an urgent need for feeding the world's population in 2050, according to the speaker?

Question 23: Where should most of the money be invested to feed the ever-growing population?
问题23：为了养活不断增长的人口，大部分资金应该投资在哪里？
Question 24: Why does the speaker give credit to the world's agricultural scientists?
问题24：为什么演讲者对全球的农业科学家给予赞扬？
Question 25: What makes China exceptional in comparison with the rest of the world?
问题25：与世界上其他国家相比，是什么让中国显得如此特别？
