阅读理解短文
Humans have names,of course,and dogs and cats may react when their names are called.
Some ocean animals,including the dolphin,invent their own names when they are very young.
And the birds called parrots may also use names.Each of these naming animals also have the
ability to learn and say individual new sounds throughout their lives,as does the African elephant,
the research shows.
African elephants are among the largest animals that live on land.They call each other by
and answer to individual names,a new study finds.Such communication is rare in the animal
world.The names are one part of the low sounds,or rumbles,elephants make.They can hear these
sounds over long distances where they live in the savannah-large grassy areas of land mixed with
woodlands.
Scientists believe that animals with complex social structures may be more likely to use in-
dividual names.Stuart Pimm of Duke University is an ecologist who was not involved with the
study.He said:"If you're looking after a large family,you've got to be able to say,Hey,Virginia,
get over here!"
The study was released in the publication Nature Ecology and Evolution.In the study,bi-
ologists used machine learning to find the use of names in recordings of savanna elephant sounds
The sounds were recorded at Kenya's Samburu National Reserve and Amboseli National Park.
The researchers followed the elephants as they traveled to observe which one called out and which
2
one appeared to answer.By examining only the audio data,the computer model predicted which
elephant was being called 28 percent of the time,likely due to the inclusion of its name.When fed
meaningless data,the model only correctly predicted eight percent of calls.
Researchers tested their results by playing recordings to individual elephants.The elephants
reacted more energetically,moving their ears and lifting their trunks,to recordings that contained
their names.Sometimes elephants did not react in any way to the sounds of elephant names other
than their own.
Ecologist George Wittemyer,who helped write the study,said "Elephants are incredibly social,
always talking and touching each other-this naming is probably one of the things that underpins
their ability to communicate to individuals."

答案与逐题解析
正确答案:28-30BCA
1.28.B (introduce the topic)
考点:写作意图推断
语境逻辑:第一段先列举人类、猫狗、海豚、鹦鹉等动物对名字的反应或使用能力,最后引出”
非洲象也有终生学习新声音的能力”,而下文主体内容均围绕非洲象的”名字交流”展开。
逻辑分析:通过提及多种动物的命名现象,自然过渡到本文核心话题—非洲象的个体名字使
用,属于典型的”引出话题”手法。其他选项:A(质疑结果)与原文肯定语气不符;C(例证论
点)此时论点尚未提出;D(呈现假设)第一段描述的是已知现象,非假设。
2.29.C (African elephants use individual names when communicating)
考点:细节理解与信息比对
语境逻辑:第二段明确指出”African elephants..call each other by and answer to individual
names”,且后文研究结果(听到自己名字反应更强烈)进一步证实这一点。
辨析:A(动物间交流罕见)偷换概念,原文说"Such communication(指用个体名字交流)is rare'”;
B(非洲象听不到远距离低频声音)与第二段”They can hear these sounds over long distances”
矛盾;D(社会结构简单的动物倾向用名字)与第三段”animals with complex social structures
may be more likely to use individual names”相反。C项与原文完全一致。
3.30.A (They used the computer model to analyze the audio data.)
考点:细节理解与动作描述
语境逻辑:第四段提到biologists used machine learning to find the use of names in recordings.
By examining only the audio data,the computer model predicted..”,明确说明研究中使用计算
机模型分析音频数据。
辨析:B(跟踪大象记录日常话动)错误,原文是”followed the elephants as they traveled to
observe which one called out and which one appeared to answer”,观察的是呼叫与▣应,非日
常:C(用机器学习与大象交流)无中生有,机器学习用于分析声音,非交流:D(对一群大象
播放录音测试)与第五段”playing recordings to individual elephants”不符。A项准确概括研究
方法。
