进入2008年,饥饿这个与人类文明共存千年的幽灵不但未曾离开,反而以令人忧虑的速度在全世界蔓延。在世界银行和国际货币基金组织春季年会上,“新的粮食和农业危机正在形成”已成为共识。为此,我国政府除了采取积极的政策措施,竭尽全力扶持农业生产外,还积极加大农业科技投入,努力提高粮食产量。如何采用科学种田方法,在努力提高单位面积产量的同时又能保证粮食生产的可持续发展,是当前人们关注的一个重点问题,很有可能成为2009年生物高考的命题热点。
Entering 2008, hunger, the ghost that has lived with human civilization for thousands of years, has not only left but has spread at an alarming rate all over the world. At the spring annual meeting of the World Bank and the International Monetary Fund, “a new crisis of food and agriculture is taking shape” has become a consensus. To this end, our government, apart from adopting active policy measures and doing its utmost to support agricultural production, has also actively increased investment in agricultural science and technology and made efforts to increase grain output. How to adopt the scientific method of farming and strive to increase yield per unit area while ensuring the sustainable development of grain production is a key issue that people are currently concerned about and is likely to become the hot topic of the 2009 college entrance examination.
