广播电视英语短句 第 225 课：灌溉系统-4

People in the two villages with the systems were able to eat three to five more servings of vegetables per day. 使用灌溉系统的两个村落的村民可以3-5个多月每天吃到蔬菜。

But making the surplus available at markets also had a wider effect. 然而，将多余的蔬菜卖到市场也起到更广泛的影响。

The study compared the villages with two others where women farmed with traditional methods like carrying water in buckets. 研究比较了此村和妇女使用传统方式——木桶挑水的耕地的 另外两个村落 。

The amount of vegetables eaten in those villages also increased, though not as much. 那些村落可吃的蔬菜总量也增加了，就是增长副度不是太大。
