Despite having a brain no bigger than the 28 of your index finger, pigeons have a very impressive 29 memory. Recently it was shown that they could be trained to be as accurate as humans at detecting breast cancer in images.Rat are often 30 with spreading disease rather than 31 it, but this long-tailed is highly 32 Inside a rats nose are up to 1,000 different types of olfactory receptors whereas humans only have 100 to 200 types.

Despite having a brain no bigger than the 28 of your index finger, pigeons have a very impressive 29 memory. Recently it was shown that they could be trained to be as accurate as humans at detecting breast cancer in images.名词：(D) nuisance (E) peak (M) tip动词：(B) examine (C) indicate (J) specify形容词，副词，分词：(A) associated (I) slight (F) preventing (N) treated (G) prohibiting (O) visual（H) sensitive【27】、dirty birds and an urban 27 ，and表并列，前面不好，后面也是不好的东西，27 是个名词，三个名词，peak山峰; 最高点，好的。tip尖端; 小费; 建议，中性。Nuisance不认识也没关系，它了。【 28】no bigger than the 28 of your index finger。28为名词，不比食指尖大。答案 (M) tip【29】very impressive 29 memory，29作定语，先找形容词，一时找不到，放放。detecting breast cancer in images在图像中检测乳腺癌，瞻前顾后。找个单词与image(影像)相关的词不难。(O) visualvul adj.视觉的（vis=see）参考译文：鸽子往往被视为肮脏的鸟类和城市的麻烦，但它们只是最新的一系列动物，已被发现有能力帮助人类。尽管你的大脑不比食指尖大，但鸽子的视觉记忆非常令人印象深刻。最近有研究表明，他们可以被训练成为像人类一样准确地在图像中检测乳腺癌。三、Rat are often 30 with spreading disease rather than 31 it, but this long-tailed is highly 32 inside a rats nose are up to 1,000 different types of olfactory receptors whereas humans only have 100 to 200 types. This gives rats the ability to detect 33 smells. As a result, some rats are being put to work to detect(肺结核). When the rats detect the smell, they stop and rub their legs to 34 a sample is infected .名词： (E) peak 动词：(B) examine (C) indicate (J) specify形容词，副词，分词：(A) associated (I) slight (F) preventing (N) treated (G) prohibiting （H) sensitive【 30】Rat are often 30 with spreading disease老鼠常 和疾病。这个位置，不是名词，不为动词原型，只能从修饰词中找。(A) associated 代入，构成被动句，表示一种状态。译为：老鼠常和疾病联系在一起。完美。【31】rather than是一个并列连词，前有spreading, 31也肯定是ing形式，ing形式有两个：一个是(F) preventing，另一个是(G) prohibiting。 Pro=pre=before； vent=go；prevent是在前边先走一步，有“预防; 阻碍; 阻止”之意。Prohibit中，hibit=hold，语气更强。有“禁止，阻止，防止; 不准许”，老鼠不听你的话，选(F) preventing。俩个近意词，只有一个是可能是备选答案，因此把(F) preventing，(G) prohibiting同时从备选答案中划去。【32】this long-tailed is highly 32 inside a rats nose。32 是个形容词，不好找，不费时间，lets go，后边有the ability to detect探测能力。由此联想到“感觉，灵敏”，如警犬。因此32 的答案是：（H) sensitive。【33】由【32】的逻辑分析。This gives rats the ability to detect 33 smells。33 稀少的气味。答案是(I) slight【34】legs to 34 不定式后是动词原形，这样的动词有三个，(C) indicate明显正确。参考译文：老鼠往往与传播疾病有关，而不是预防疾病，但这种长尾是高度敏感的，在老鼠的鼻子上有多达1000种不同类型的嗅觉受体，而人类只有100到200种。这使老鼠有能力发现轻微的气味。结果，一些老鼠被用来检测（肺结核）。当老鼠检测到这种气味时，他们会停下来揉揉腿，以表明样本被感染了。四、Traditionally, a hundred samples would take lab technicians more than two days to 35 but for a rat it takes less than 20 minutes. This rat detection method doesnt rely on specialist equipment. It is also more accuratethe rats are able to find more TB infections and, therefore, save more lives. 名词： (E) peak 动词：(B) examine (J) specify形容词，
