23、. When and where dogs first began living side by side with humans are questions that have stirred hot debate among scientists. There are a few hard facts that all agree on. These include that dogs were once wolves and they were the first animal to be domesticated(驯养) by humans. They came into human
24、lives about 15, 000 years ago, before the dawn of agriculture.Beyond that, there is little agreement. The earliest bones found that are unquestionable dogs and not wolves date from 14, 000 years ago. However, 30, 000yearold skulls have been discovered in France and Belgium that are not pure wolves a
25、nd some scientists think could be dogsWith such puzzling evidence, many scientists are now turning to DNA to find out when and where dogs were first domesticated. In one research project, tens of thousands of blood samples have been taken from street dogs around the world. The plan is to compare the
26、m with those of wolves. Its even possible to analyse DNA from ancient bones. Tiny pieces of the 30, 000yearold skulls mentioned earlier are currently being studied, and another DNA study has already shown that ancient dogs preserved in the Alaskan ice fields evolved from Asian wolves, not American o
27、nes.Indeed, the ancient DNA may turn out to be more informative than the DNA of living dogs. Because dogs have accompanied humans around the world for thousands of years, their current distribution may tell us very little of their origins. This is why different groups of scientists believe that dogs
28、 variously originated in eastern Asia, Mongolia, Siberia, Europe or Africa.But why were the animals domesticated in the first place? The most recent theory is that dogs domesticated themselves, initially living in and around our ancient villages to eat any food thrown out. Today, this is a way of li
29、fe still shared by three quarters of a billion unowned dogs worldwide.28Which is the only statement generally agreed on by scientists studying dogs?ADogs originally were used as farm animals.BDogs evolved from wolves found in Europe.CDogs helped the development of agriculture.DDogs were the first an
30、imal to be kept as pets.29Why does the writer first mention the 30, 000yearold animals skulls?ATo show that dogs were much larger in the past.BTo prove that dogs developed from Asian wolves.CTo suggest that dogs may have evolved much earlier.DTo argue that dogs were first kept in France and Belgium.
31、30How did scientists determine the origins of the ancient dogs found in Alaska?ABy analyzing the age of their bones.BBy examining the animals DNA.CBy studying the shape of their skulls.DBy comparing them with modern dogs.31Why did dogs start living with humans?ABecause they were attracted by food.BB
32、ecause they were trapped by humans.CBecause they couldnt survive in the wild.DBecause they were trained to protect villages.DClassifying things is critical for our daily lives. For example, we have to detect spam mail(垃圾邮件), false political news. When we use AI, such tasks are based on “classificati
33、on technology” in machine learninghaving the computer learn, using the boundary separating positive and negative data. For example, “positive” data would be photos including a happy face, and “negative” data photos that include a sad face. Once a classification boundary is learned, the computer can
34、determine whether certain data are positive or negative.However, the difficulty with this technology is that it requires both positive and negative data for the learning process, and negative data are not available in many cases. For instance, when a retailer(零售商) is trying to predict who will make
35、a purchase, they can easily find data on customers who have purchased from them(positive data), but it is basically impossible to obtain data on customers who have never purchased from them(negative data), since they do not have access to their competitors data.According to lead author Takashi Ishid
36、a from RIKEN AIP, “Previous classification methods could not cope with the situation where negative data were not available, but we have made it possible for computers to learn with only positive data, as long as we have a confidence score for our positive data, constructed from information such as
37、buying intention or the active rate of app users. Using our new_method,_we can let computers learn a classifier only from positive data equipped with confidence.”According to Ishida, “This discovery could expand the range of applications where classification technology can be used. Even in fields wh
38、ere machine learning has been actively used, our classification technology could be used in new situations where only positive data can be gathered due to data regulation or business constraints(限制). In the near future, we hope to put our technology to use in various research fields, such as natural
39、 language processing, computer vision, robotics, and bioinformatics.”32How can the computer distinguish the positive data from the negative data?ABy learning the classification boundary.BBy updating the data collected regularly.CBy separating happy faces and sad ones.DBy introducing classification t
40、echnology.33Why is the example mentioned in Paragraph 2?ATo prove how important the positive data are.BTo confirm that data on customers are complete.CTo argue that retailers get their competitors data.DTo explain why negative data are hard to acquire.34What do the underlined words “new method” in P

44、ok away so fast？What does it all mean？！When youre an overthinker, you tend to find meaning in the world around you. Its helpful to remind yourself that things mean the meaning you give them.You think more than you do.Sometimes you think so much that you dont end up doing anything. You weigh the choi

By recognizing that this can be a strength as well as a weakness, you should know that you simply cant get everything right,

You can even teach someone else who underthinks!AYou may continue thinking about it even when you believe you have already let it go.BYou assume that others know what youre thinking about.C

80、idge and a railway bridge, and its just a short drive from Conway.”可知，乘火车可以抵达Anglesey，故选B。22D解析：细节理解题。根据第四段最后一句中的“spent the next 50 years building the town of Portmeirion with a style of Italy”可知，在Portmeirion可欣赏到意大利风格的建筑，故选D。23C解析：细节理解题。根据倒数第二段“Over 30 ideas for adventure activities and sports, both
81、 traditional and extreme.”可知，在旅游手册上可以看到关于冒险活动的介绍，故选C。【解题导语】本文是一篇记叙文。一只名为Jessica的鹰出生时无法站立，双翅折断，医生对此也无能为力，不料后来它竟然能够站立了。6年后，“我”患了癌症，Jessica陪“我”度过了那段人生中的艰难时期我们从初次见面时就已成了知己。24B解析：词义猜测题。根据第二段第二、三句“It got to the point where an awful decision had to be made if she couldnt stand in a week. It looked like dea
82、th was winning.”可知，如果她一个星期后站不起来，那就到了不得不做一个很坏的决定的地步了。看来死神就要赢了。结合该句“She was going to be put down that Friday.”可知，那个星期五，她将被杀死。故B项“无痛苦地被杀死”符合语境，故B项正确。25B解析：推理判断题。根据第二段尾句“I was just about in tears.”可知，当看到她能站起来时，“我”快要哭了。据此可以推断，看到她站起来时，作者感到很激动，故B项正确。26C解析：细节理解题。根据第四段第三、四句“When I felt good enough, I would t
83、ake Jessica out for walks. Jessica would also come to me in my dreams and help me fight the cancer time and time again.”可知，当“我”感觉足够好的时候，“我”会带Jessica出去散步，Jessica也会出现在“我”的梦中，一次又一次地帮助“我”与癌症作斗争。据此可知，当作者被诊断患癌症后，作者从Jessica那里得到了精神支持，故C项正确。其他三项文章中都没有提及。27A解析：标题归纳题。通读全文可知，本文主要讲述了一只名为Jessica的鹰和“我”的故事，故A项最适合作为
84、本文标题。【解题导语】本文是一篇说明文。研究发现，狗是从狼驯养而来的，早在大约一万五千年之前狗就进入了我们的生活。科学家通过分析DNA去查证狗最初是在何时何地被驯养的。28D解析：细节理解题。根据第一段中的“There are a few hard facts that all agree on.These include that.the first animal to be domesticated(驯养) by humans.” 可知，狗是第一种被人类驯养成宠物的动物，故D项正确。29C解析：推理判断题。根据第二段第三句“However，30, 000yearold skulls hav
85、e been discovered in France and Belgium that are not pure wolves and some scientists think could be dogs”可知，在法国和比利时已经发现了三万年前的头骨，它们不完全是狼的，科学家认为有一些可能是狗的。而第二段第二句表示最早发现的狗骨头是14 000 年前的，据此可推知，该处提及三万年前的头骨旨在说明狗的进化历史更早，故C项正确。30B解析：细节理解题。根据第三段尾句中的“another DNA study has already shown that ancient dogs preserve
86、d in the Alaskan ice fields evolved from Asian wolves, not American ones”可知，科学家是通过检测DNA的方法来判断阿拉斯加狗的起源的，故B项正确。31A解析：推理判断题。根据尾段第二句“The most recent theory is that dogs domesticated themselves, initially living in and around our ancient villages to eat any food thrown out.”可知，最近的一种说法是，狗是自己驯养自己的，最初生活在我们古
87、老的村庄里或周围，吃人们扔掉的食物。据此可推知，狗和人生活在一起的原因是它们被食物所吸引，故A项正确。【解题导语】分类对我们的日常生活至关重要。然而在分类技术机器学习过程中，分类既需要积极的数据，也需要消极的数据，而消极的数据在很多情况下是很难获得的。现在科学家能用分类技术使机器只识别积极的数据。32A解析：细节理解题。根据第一段最后一句“Once a classification boundary is learned, the computer can determine whether certain data are positive or negative.”可知，一旦学习了分类边界
