难道不觉得奇怪么? B选项两种情况, 1、有杀虫剂的稻田虫子狂吃棉花毁坏,没有杀虫剂的稻田虫子也狂吃棉花毁坏——>棉花毁坏是因为很多虫子在狂吃(能排除“不是产生抗药性”么,你想想,有杀虫剂的他都吃了,就算没有抗药性,没杀虫剂的他当然要吃啊,死都死过一回了) 文章中有小小的程度区别,这是否是关键?? 文章:This year the plantings are being seriously damaged by bollworms So it is likely that the cotton is simply being overwhelmed by corn-bred bollworms.(说明今年的毁坏是虫子以数量取胜,不是因为有抗药性) 选项:Whether plantings of cotton that does not produce the insecticide are suffering unusually extensive damage from bollworms this year(如果没有杀虫剂的毁坏程度比有杀虫剂的毁坏程度更深,那么就可以证明:没有抗药性,而是因为虫子多) 2、有杀虫剂的稻田虫子狂吃,但是没有杀虫剂的稻田虫子不吃——>说明虫子有抗药性 Orz...这种情况很搞笑,这虫子傻啊,就是为了证明自己有抗药性,就啃着杀虫剂狂吃... |
