A facial recognition app, recently developed by scientists, will make it easier to identify (辨认) pandas.
Wan Yongqing, a Beijing photographer, visits Sichuan Province to take photos of pandas every other year. He has watched therm for more than a decade. "My friends say I'm a big panda fan. It is a shame that I find all pandas look the same, with black eyes and white fur. It does not matter as all the pandas are cute to me," he said.
Yet, identifying one panda from another does mater to researchers, according to Zhang Zhihe, chief of the Chengdu panda research base.
"Identifying individual pandas is important for conservation (保护) management and research. For captive(圈养的) pandas, it is important for their daily feeding schedules. family background and data(数据) management. For wild pandas, it helps researchers study their population structure and provides scientific support for their a protection and management," he said.
China has carried out four scientific surveys on wild pandas, and now has a big databank about them. The number of wild pandas in China is mostly known. However, it is still difficult to know the age, sex, heath and other scientific information about the population.
"It is difficult to track and watch the structure because wild pandas tend to live alone, deep in the mountains, and their living environment is vast," Zhang added.
In 2017, the Chengdu base began researching individual panda identification technology by analyzing images. Over the past two years, they have built a databank of more than 120.000 images, over 10,00 video clips, and completed organizing nearly 10,000 images.
Using the databank, researchers have started a facial recognition app that can accurately recognize captive pandas by analyzing and comparing the unique features of panda faces.
Panda researchers hope the data and Al technology will help them analyze data fort both captive and wild pandas.
28. Why is it important to identify individual captive pandas?
A.It is helpful for further research and data management.
B. It is useful for studying their population structure.

Six Chinese survived(幸存) the legendary tragedy of the RMS Titanic (泰坦尼克号) but disappeared soon after. Now a British director, Arthur Jones, will uncover their stories and histories of discrimination(歧视).
There were eight Chinese between the ages of 24 and 37 on the Titanic, boiler workers sharing one 59-pound third-class ticket, according to the record of Titanic Cruise Line but only six survived from its sinking. When they arrived in the United States, they were not helped, like the other 705 survivors. Instead they were forced to leave the country within 24 hours, because of the Chinese Exclusion Act(排华法案) signed in 1882.
Some westerners questioned the six Chinese survivors as stowaways(偷渡者)and claimed that they survived because they secretly climbed on the lifeboat or dressed as women to board lifeboats. But Jones believes they did not do anything shameful in order to survive the disaster
after visiting foreign files, museums and cooperating with American and Chinese historians.This is not only a story about the survivors of Titanic,but also story of a group of brave Chinese people exploring the outside world at that time, he said.
To restore(还原) their ignored stories, Jones and his team found the son of Fang Lang, one of the Chinese survivors , in Wisconsin, US. In May, Jones will visit Taishan city in south China's Guangzhou province, recorded as the survivors' hometown.The filmmakers also established a website, https://www.360docs.net/doc/963888948.html,, for more clues.
Ordinarily, people think of Titanic as a story of rich white people, but don't know there were people from all over the world, including Chinese. Their stories are never told, Jones said.
31. Why did some westerners question the six Chinese as stowaways and claimed they dressed as women to board lifeboats?
A. Because they thought highly of their contribution to the Titanic
B. Because they just discriminated Chinese at that time
C. Because they were not satisfied with the service the six provided.
D. Because they thought the six were not gentlemen.
32. Which of the following statements is NOT TRUE?
A. Jones holds an opinion that the six did something against the law.
B. The six Chinese's stories have never been told before.
C. There were 8 Chinese between the ages of 24 and 37 on the Titanic.
D. The six Chinese were forced to leave within one day after they landed in US.
33. What does the underlined word“established" in the fourth paragraph mean?
A. look for
B. work out
C. set up
D. pick up
34. What's the author's purpose of writing this passage?
A. To share some specific details of the tragedy of the RMS Titanic.
B. To honor the brave heroes who passed away in the terrible accident.
C. To tell us a British director will uncover the stories of 6 Chinese Titanic surviv ors.
D. To tell some history stories in which westerners looked down upon Chinese.

Scientists have already studied how dogs respond to people's behavior and speech. But researchers are just scratching the surface of human-cat interactions.House cats do appear to respond to the expressions on people's faces. Cats can also tell different human voices. But can cats recognize their own names?
Saito, a psychologist at Sophia University in Tokyo, and her colleagues decided to find the answer. They asked the owners of 77 cats to say four nouns of similar length followed by the cat's name Cats gradually lost interest with each random (随机的) noun. But when the owner said a cat's name, the cats reacted strong. They moved their ears, head or tail, changed their back paw position.And, of course, they meowed.
These findings mean that cats join the ranks of animals that have shown some sort of response in experiments to the names people give them. Those animals include dogs, dolphins, apes and parrots. It's hard to compare across species(种类), though. Some dogs,for example, can tell the difference between hundreds of human words.
The study makes a strong case that cats are perfectly capable of recognizing their own names.
Getting a treat or hugs as a reward (奖励)is part of how cats learn to recognize a name. However, owners may also use their cat's name in a negative setting, like yelling at Fluffy to get off the stove. As a result, cats can probably learn to associate these familiar utterances with good and bad experiences,Saito notes. And that might not be great for cat-human relations. So only using a cats name in a positive context and using a different term in a negative context could help cats and humans communicate more clearly.
So cats may recognize their names. But will they come when called? Don't get your hopes up.
35. What made cats react strongly according to Saito's study?
A.Their owners.
B. Their own names.
C. A random noun.
D. A delicious meal.
36. The author mentioned dogs in Paragraph 3 to show__________.
A. they can recognize hundreds of human words
B. it's easy to tell their difference from other animals
C. it's difficult to make a comparison among animals
D. they will respond on hearing of their names like cats
37. What does the underlined word "utterances" in Paragraph 4 mean?
A. Words.
B. Situations.
C. Observations.
D. Owners.
38. What should people avoid to improve human-cat communication?
A. Giving a treat or hug as a reward.
B. Calling their name in a positive context.
C. Using a different term in a negative setting.
D. Associating their name with bad experiences.

高一语文期中考试试卷 （本试卷分为两部分，共22道题，满分150分，考试时间150分钟。） 第Ⅰ卷（阅读题共66分） 一、现代文阅读(9分，每小题3分) 阅读下面的文字，完成1-3题。 中国的篆刻艺术，其实就是在金属、象牙、犀角、玉石等材质上以篆体文字雕刻的艺术。因以制作印章为主，又称印章艺术。作为国粹之一，它经历了漫长的发展过程，形成了一以贯之及厚重的悠久传统。其融万千气象于方寸之间，向来为历代文人墨客所钟爱。或自篆自用，或馈赠文友，钤记落款，观赏把玩，可从中获得无尽的审美愉悦和艺术享受。 考篆印之滥觞，当不晚于周代。当前所发现的最早实物，可确定为东周遗物，学界亦普遍接受“我国篆印源于春秋而盛于战国”的论断。但从当时篆刻艺术的成熟程度论之，此前当有相当漫长的发展过程。商周时期普遍应用的甲骨文，就是以刀为笔，刻在龟甲兽骨之上而成的，广义而言亦可归入篆刻艺术之内。河南安阳殷墟曾出土过颇似当今印章的铜玺，字迹清晰，斑斑可考，或可视为印章艺术之先河。 古人崇尚诚信，因而对作为诚信物证的印玺十分重视。先秦时期，古风犹存，等级观念尚不严备，无论官印、私章，皆可称“玺”，且样式五花八门，美不胜收。到秦汉时，专制制度正式确立，社会等级日益森严，“玺”成为了皇帝王侯印章之专用名称，其他人的印信只能以“印”“章”“记”等名之，且尺寸、样式也有严格规定。汉代时，篆刻印章十分兴盛，到达顶点。考其原因，乃由于秦代实行“书同文”，废六国古文字，独行秦国创制的小篆字体，而比篆晚出之隶、草、楷、行等字体尚未行世，故篆文居官方正式字体地位，因而大盛。另两汉社会稳定，冶炼业和手工制作业发达，使得汉印的艺术取得长足进展，水平空前，而成为历代篆刻家尊奉临摹之典范。 就制作方法而论，汉印多以黄铜浇铸而成，但浇铸前须将印文反刻于陶范内壁；而部分急就章乃直接用铜坯凿成，如“某某将军章”等；另有一部分乃就玉材而雕琢。因此，三者尤其是后两者被认为是现代篆刻艺术之始祖。 印章文字，有凹凸两种，凹者称阴文，凸者称阳文，也有阴阳合璧者。因印泥多取朱色，故钤盖印蜕后，阴即白，阳即朱，遂又有“白文”“朱文”之目。印面虽风韵万端，但也无非是依阴阳二体间组合搭配以求变化。阴文之美，无阳文之衬托则不可能存在，反之亦然。二者相互制约又相辅相成，故而“分朱布白”“虚实有致”乃印人需潜心探索的治印之道。真可谓是高深莫测，奥妙无穷。 篆刻就布局而言，有字法、章法之分。字法乃用字写字之法。包括选取字体、反书于印面等环节。不同时代之字体，切不可出现于同一印章之内。而字之书写，乃印家书法功力的集中体现。而所谓章法，指将所有印文排列于印面的艺术，要力求疏密有致，彼此呼应，向无定法，气象万千，这应该是篆刻艺术最重要的一环。因为即使印家刀法熟练，而章法却幼稚，亦绝无佳作可言。尤其是同一字两次以上出现于同一印章时，每字则不可取同。而成套成组之印章，须方方有别，显示其作者的章法功力。所以在设计印稿时必反复构思，用尽解数。当然既是印家，便多是“心中有字”“胸内有法”。 1.下列对于中国篆刻艺术的理解，不正确的一项是（） A．中国的篆刻艺术属于国粹，又称印章艺术。它是在金属、象牙、犀角、玉石等材质上雕刻篆体文字的艺术。 B．中国篆刻艺术的起源应该不会晚于周代，中国篆刻艺术经历了漫长的发展过程，从而形成了一以贯之以及厚重的悠久传统。 C．中国篆刻艺术有凹凸两种形式，分别称为阴文和阳文，也有阴阳合璧者；由于印泥多用朱色，又有“白文”“朱文”的说法。 D．中国篆刻艺术在章法上疏密有致，彼此呼应，使万千气象融于方寸之间，让人从中获得无尽的审美愉悦和艺术享受。 2.下列理解和分析，不符合原文意思的一项是（） A．古人崇尚诚信，人们对作为诚信物证的印玺十分重视。等级观念尚不严备的先秦时期，玺的样式五花八门，美不胜收。 B．汉代篆刻印章大盛的原因：一是小篆居官方正式字体地位且独行于世，二是当时社会稳定、冶炼与手工业发达。 C．印章的印面依据阴阳二体间的组合搭配来求得变化，二者相互制约又相辅相成，进而取得奥妙无穷的效果。 D．印家的“心中有字”是指篆刻布局中将所有印文排列于印面的章法，这也是篆刻艺术最重要的一环。 3.根据原文内容，下列理解和分析不正确的一项是（） A．甲骨文在广义上可归入篆刻艺术之内，殷墟曾出土过颇似当今印章的铜玺大致可以视为印章艺术的先河。 B．就制作方法而论，现代篆刻艺术的始祖被认为是汉代直接用铜坯凿成的急就章和用玉材雕琢的印章。 C．篆刻中的字法包括字体的选择和反书于印面的书写等环节，后一环节是印家书法功力的集中体现。 D．设计印稿的印家需要反复构思，使尽解数让成套和成组的印章方方有别，从而显出自己的章法与功力。 二、文言文阅读 （一）课内文言知识（每题2分，共10分） 4.下列选项中文言句式跟其他三项不同的是（）（2分） A.夫晋，何厌之有？ B.大王来何操？
