Questions 1 to 10 are based on the following passage. A rat or pigeon might not be the obvious choice to tend to someone who is sick, but these creatures have some 1 skills that could help the treatment of human diseases. Pigeons are often seen as dirty birds and an urban 2 , but they are just the latest in a long line of animals that have been found to have abilities to help humans. Despite having a brain no bigger than the 3 of your index finger, pigeons have a very impressive 4 memory. Recently it was shown that they could be trained to be as accurate as humans at detecting breast cancer in images. Rats are often 5 with spreading disease rather than 6 it, but this long-tailed animal is highly 7 . Inside a rat's nose are up to 1,000different types of factory receptors(嗅觉感受器),whereas humans only have 100 to 200 types.This gives rats the ability to detect 8 smells. As a result, some rats are being put to work to detect TB (肺结核). When the rats detect the smell, they stop and rub their legs to 9 a sample is infected. Traditionally, a hundred samples would take lab technicians more than two days to 10 ,but for a rat it takes less than 20 minutes. This rat detection method doesn't rely on specialist equipment. It is also more accurate the rats are able to find more TB infections and, therefore,save more lives.注意:此部分试题请在答题卡2上作答。A. associated B.examine C. indicate D.nuisance E. peak F.preventing G. prohibiting H.sensitive D slight J.specify K.superior D.suspicious M.tip N.treated O. visual

解析
文章讨论了鸽子和老鼠等动物在帮助人类治疗疾病方面所具有的特殊技能。鸽子和老鼠虽然通常被认为是不受欢迎的动物，但它们在医学检测方面表现出色。
步骤 2：分析每个空格的语境
1. 空格1：根据上下文，这里需要一个形容词来描述鸽子和老鼠的技能，这些技能能够帮助治疗人类疾病。因此，选择“superior”（优越的）。
2. 空格2：根据上下文，这里需要一个名词来描述鸽子在城市中的形象。因此，选择“nuisance”（麻烦）。
3. 空格3：根据上下文，这里需要一个名词来描述鸽子的大脑大小。因此，选择“tip”（尖端）。
4. 空格4：根据上下文，这里需要一个名词来描述鸽子的记忆。因此，选择“visual”（视觉）。
5. 空格5：根据上下文，这里需要一个动词来描述老鼠与疾病的关联。因此，选择“associated”（关联）。
6. 空格6：根据上下文，这里需要一个动词来描述老鼠在疾病传播中的作用。因此，选择“preventing”（预防）。
7. 空格7：根据上下文，这里需要一个形容词来描述老鼠的嗅觉能力。因此，选择“sensitive”（敏感的）。
8. 空格8：根据上下文，这里需要一个形容词来描述老鼠能够检测到的气味。因此，选择“slight”（微弱的）。
9. 空格9：根据上下文，这里需要一个动词来描述老鼠如何表示样本被感染。因此，选择“indicate”（指示）。
10. 空格10：根据上下文，这里需要一个动词来描述实验室技术人员如何处理样本。因此，选择“examine”（检查）。
