1.[B]题干的句子是文章第1段第3句，这是一个带有插入语的简单句，contrary在此表示跟partofnature相反，因此答案为B。
2.[D]第2段最后一句提到，我们必须更加关注吸收少量杀虫剂的潜在后果，它们正在不知不觉地污染我们的世界。因此，作者对杀虫剂对环境的影响关注且担忧,D符合题意。
3.[A]第2段第2句提到，杀虫剂使人突然发病或者死亡是很令人难过的亊，对于人口整体来说，人类对杀虫剂长期累计的潜在后果的认识不足，才是最严重的问题，故选A。
4.[C]根据第3段倒数第2句说的“对未来的灾难无动于衷是人的本性”以及最后一句说的"大多数人只对有明显迹象的疾病予以关注”可知C正是人们忽视化学药物的潜在危害的原因，故选C。
5.[D]Dubos博士话中“最可怕的敌人”指的是“杀虫剂引起的潜在危险”，博士话中的slowlyapproachthemunnoticed直接表明D正确。
