广播电视英语短句 第 168 课：转基因农作物-3

She says they found that genetically engineered crops can be better for the environment. 她表示，他们发现转基因农作物更易于与环境相适应。

For example, she noted that crops designed to resist damage by glyphosate （ 草甘膦 ） need fewer pesticides （杀虫剂） that are more toxic to the soil. 例如，她指出，通过基因改造抵抗草甘膦的农作物需要的杀虫剂更少，而杀虫剂对土壤具有更大的毒害作用。

Glyphosate is a chemical used in Round-Up and other weed killing products. 草甘膦作为一种化学药品适用于 Round-Up （一种除草剂）和其他除草产品。

But some farmers have used so much glyphosate that a number of kinds of weeds can now resist it. 但是，一些农民使用大量的草甘膦，使得许多种类的杂草如今获得了抵抗力。
