广播电视英语短句 第 72 课：减少农业用水量-3

Tommy Carter says the soybeans they grow are for the most part genetically similar. 汤米卡特说农民们种植的大豆大部分在基因方面是相似的。

More differences, or diversification, could better protect crops against climate changes that can reduce production. 更多的差异或者品种的多样化可以使得农作物抵抗会导致减产的气候变化。

Those changes include water shortages which could increase from global warming. 这些气候变化包括随温室效应加剧的水资源缺乏问题。

The Agriculture Department has a soybean germplasm collection, a collection of genetic material passed from one generation to the next. 农业部拥有一个大豆胚质的样本收藏，是关于代代相传的基因物质的。

Members of Team Drought studied more than two thousand five hundred examples from the collection. 干旱小组的成员们研究了集合中超过2500个样本。
