题目解析：
【题目翻译】第5段对昆虫种群的Bt抗性提出了以下所有要求，除了
A：经常使用Bt杀虫剂并没有产生抗药性的昆虫种群，因此使用Bt植物可能也是安全的。
B：如果转基因植物的广泛使用，最终会发生抗Bt昆虫种群的进化。
C：因为bt植物在任何时候和所有组织中都是有毒的，它们只允许抗bt的昆虫生存和繁殖。
D：在Bt植物旁边种植非转基因植物可能有助于Bt易感昆虫保持种群的一部分。
【判定题型】：根据题干中出现的大写“EXCEPT”/"NOT" 等其他明显表示否定的词，可以判定本题为否定事实信息题，需要找出与原文信息不符的那个答案。
【关键词定位】：根据题干关键词“Bt resistance”,可以将出题范围锁定在Passage5。
【选项分析】
选项A涉及到Bt杀虫剂不会导致昆虫产生抗性，所以具有Bt基因的作物的使用是安全的，不对，Bt基因作物的使用是有风险的，整段都在讲这种作物使昆虫产生抗药性的事情；选择A。
选项B涉及到We know that evolution will occur when transgenic plants grown on a large scale over a period of time，是这句话的同义转述，正确；
选项C是涉及到However, transgenic Bt plants express the toxin in all tissues throughout growing season. Therefore, all insects carrying genes that make them susceptible to the toxin will die.Bt基因的作物会杀死除了带有抗性基因的所有昆虫，正确；
选项D 依据for example, planting nontransgenic border rows to provide a refuge for susceptible insects，种植不带转基因的作物使解决办法之一，正确。
We know that evolution will occur when transgenic plants grown on a large scale over a period of time. Of special concern is the development of insect populations resistant to the Bt toxin. This pesticide has been applied to plants for decades without the development of insect-resistant populations. However, transgenic Bt plants express the toxin in all tissues throughout growing season. Therefore, all insects carrying genes that make them susceptible to the toxin will die. That leaves only the genetically resistant insects alive to perpetuate the population. When these resistant insects mate, they will produce a high proportion of offspring capable of surviving in the presence of the Bt toxin. Farmers are attempting to slow the development of insect resistance in Bt crops by, for example, planting nontransgenic border rows to provide a refuge for susceptible insects. These insects may allow Bt susceptibility to remain in the population.
