【典例示例】（2021年6月，浙江卷阅读理解C篇）
If you ever get the impression that your dog can "tell" whether you look content or annoyed, you may be onto something. Dogs may indeed be able to distinguish between happy and angry human faces, according to a new study
Researchers trained a group of 11 dogs to distinguish between images（图像）of the same person making either a happy or an angry face. During the training stage, each dog was shown only the upper half or the lower half of the person's face. The researchers then tested the dogs' ability to distinguish between human facial expressions by showing them the other half of the person's face on images totally different from the ones used in training. The researchers found that the dogs were able to pick the angry or happy face by touching a picture of it with their noses more often than one would expect by random chance.
The study showed the animals had figured out how to apply what they learned about human faces during training to new faces in the testing stage. "We can rule out that the doge simply distinguish between the pictures based on a simple cue, such as the sight of teeth," said study author Corsin Muller. "Instead, our results suggest that the successful dogs realized that a smiling mouth means the same thing as smiling eyes, and the same rule applies to an angry mouth having the same meaning as angry eyes.”
"With our study, we think we can now confidently conclude that at least some dogs can distinguish human facial expressions," Muller told Line Science.
At this point, it is not clear why dogs seem to be equipped with the ability to recognize different facial expressions in humans. "To us, the most likely explanation appears to be that the basis lies in their living with humans, which gives them a lot of exposure to human facial expressions," and this exposure has provided them with many chances to learn to distinguish between them, Muller said.
28. The new study focused on whether dogs can_________.
A. distinguish shapes B. make sense of human faces
C. feel happy or angry D. communicate with each other
29. What can we learn about the study from paragraph 2?
A. Researchers tested the dogs in random order.
B. Diverse methods were adopted during training.
C. Pictures used in the two stages were different
D. The dogs were photographed before the lest.
30. What is the last paragraph mainly about?
A. A suggestion for future studies. B. A possible reason for the study findings.
C. A major limitation of the study D. An explanation of the research method.

语篇解读
主题语境
人与自然---人与动物
语篇大意
本文是一篇科普类文章，文章主要介绍了一项有关狗的研究，实验研究表明，狗能够识别人类的表情是高兴还是愤怒。
背景知识
科学家已经证实，鸟类、鱼和青蛙等许多动物都存在这种大脑左右半球的情感分工：左半球负责积极的感情和行为，而右半球则相反。人类也不例外，只不过人类的情感要更丰富：爱、依赖、安全感、平静等是积极的情感，而逃避、恐惧和抑郁等则是消极的情感。由于左右大脑控制的身体部分相反，这种不对称性也表现在身体相反的一侧。比如，鸟类用右眼寻找食物（积极行为），而左眼留心“敌人”（消极行为）；人类的右侧面部肌肉用于表达高兴，而左侧的则反映忧愁。
重点单词
distinguish识别，区分； cue n.暗示:提示;信号； confidently有信心地:自信地；exposure暴露
高级短语
be onto something有所发现；figure out理解:弄明白；apply...to ...把......运用于...... ；rule out排除;不考虑；base on以......为根据；be equipped with配备着......；装备着.......
长难句分析
原文：“To us, the most likely explanation appears to be that the basis lies in their living with humans,which gives them a lot of exposure to human facial expressions, " and this exposure has provided them with many chances to learn to distinguish between them, Muller said.
分析：本句为主从复合句。appears to be后面是that 引导的表语从句，该表语从句中含有一个which引导的非限定性定语从句。
答案与解析：
28.B 主旨大意题。根据短文首段的第二句“Dogs may inxdeed be able to distinguish betweenhappy and angry human faces, according to a new study”可知，一项新的研究表明,狗可能真地可以辨别人的表情是高兴还是愤怒，紧接着后文又详细介绍了研究过程和结论，即狗能够识别人的表情，且倒数第二段的“With our study, we think we can now confidently conclude that at leastsome dogs can distinguish human faciall expressions”一句明确给出了结论。故选B项。
29.C 细节理解。根据第二段中的“Theresearchers then tested the dogs"ability to distinguish between human facial expressions byshowing them the other half of the person 's face or images totally different from the ones used intraining”可知，研究者给狗展示了与以往训练完全不同的人脸(或图片)的另一部分。故选C项。
30.B 主旨大意题。根据最后一段中的“...why dogs seem to be equipped with the ability to recognize different facialexpressions in hurmans”可知最后一段解释了为什么看起来狗具备识别人类表情的能力，也就是为什么会有这样的实验研究结论。故选B项。

英语新闻报道的文体特点       
新闻的首要职能是报道新闻时事。通常人们所说的新闻英语(Journalistic English, News English)主要是指新闻报道文章中所使用的英语,是具有新闻特性、适合新闻报道要求、适应新闻信息传播需要的语言。侯维瑞认为,新闻报道的职能是传播信息,即迅速及时地报道时事新闻,以最快的速度正确地报道国内外发生的重大事件。真实性、客观性和及时性是新闻报道的要则。反映在文体风格方面,新闻英语必须正确、简洁、明了,在有限的撰稿时间和刊登篇幅内取得言简意赅的效果。新闻英语因其自身的特点和传播功能,词汇、时态、语态及修辞等的运用都有其自成一家的特点。
1.新闻英语的词汇特点
        新闻英语作为信息传播媒介,需将信息浓缩于一个有限的空间(版面),其目的是便于读者抓住主要内容。因此,新闻英语词汇的特殊性表现在:词汇简单而具体,行文流畅而不会佶屈聱牙。新闻英语常常通过使用大写字体、戏剧性标题、简短的段落、简洁的句子来增强新闻的趣味性。此外,新闻英语还是新词的滋生地,一些新词往往是经过媒体的普及而逐步为公众所接受。
        频繁使用新词。文字是现实生活的反映,而现实生活总是在日新月异地变化。因此,在新闻英语中,时常会出现一些在原有意义上延伸出新义的词,且已经成为颇有特色的词汇。随着这些词的广泛运用,它们也逐步渗透到日常生活用语之中。例如:
        The rapid-growing death toll of AIDS victims has posed a wide spread panic across the States from gay bars in the west cost of California to the Fun City's red-light districts.艾滋病患者死亡人数激增造成普遍恐慌。恐慌波及全国,从西海岸加州的同性恋酒吧到逍遥城纽约的红灯区。
        gay 的原义为“快乐的”,但在新闻报道中已转义为“同性恋的”。此处的“gay bars”为“同性恋酒吧”而不是“快乐酒吧”。
        除延伸出新义之外,新词还可以通过加上前后缀的方式构成。其中较为常见的前缀有anti-、auto-、electro-、inter-、intra-、non-等。用派生法构成的新词一方面可以补足原有英语词汇中缺少的词义,另一方面又能使文笔简练有力。
        随着人类思维的进步和科技的飞速发展,根据资料统计,英语中每年会出现1500个左右新词。而这些新词首次亮相的舞台往往是报纸、杂志等新闻媒体。不少语言学家认为,现代英语词汇的变化在很大程度上是与新闻语言的影响有关。不少新词经新闻媒体登场后,被人仿效,逐渐得以普及,为公众所接受。
        广泛使用短词及缩略语。由于新闻栏目篇幅狭窄,出于排版的需要和对听众和观众的理解速度和能力的考虑,记者和编辑喜欢使用字型短小的单音节词和缩略词以节省刊头空间。美国新闻学家麦克道格尔在其《解释性报道》一书中提出要多用简单词。他认为,在表示同一个意思时about比with reference to好、 although比despite the fact that好。在新闻写作中,很少有人会把do说成effectuate、把end写作terminate;他们宁愿用ban而不用prohibition、用today来代替in this day and age。
        再者,新闻报道受到时间和传递量的限制,不得不在写作上力求简明扼要,用字精练通俗,句法一目了然。使用词义宽泛、形体短小的词不仅可以美化版面,而且可使文字简练。路国强先生将英语缩略词分为两种。
        一种为缩略词(acronyms),由一词组中的各主要词的第一字母缩合而成。例如:BL' S family cars, the Ital and Allegro, are considered by many motorists to be unreliable and old-fashioned in styling, according to a survey published yesterday.据昨天公布的一项调查,许多驾驶汽车的人认为:英国利兰汽车公司的家庭汽车——一伊大尔牌和阿勒格罗牌性能不可靠而且款式陈旧。(句中BL' S是British Leyland' s的缩写词)。
        另一种为缩短词(shortened words),即通过截短法(clipping)或缩短法(shortening)构成的词。如: brunch (breakfast+lunch)早午餐; telecast(television+broadcast)广播电视。一则交通事故报道说: More and more traffic experts suspect that“autocide”is an important cause of traffic deaths.(Time, Jan. 21, 1997) 这里的autocide是automobile suicide的节缩词。
        由此可见,新闻语言应使用简洁通俗的大众化语言。
        借用各类词汇。新闻英语的一大特点是常借用地名、人名、物名等专有名词来表示某一个意思。如White House指美国政府, James Bond (影片《007》中的超级间谍)被用来指无往不胜的谍报人员或其他类型的智慧人物。《High Noon》是20世纪60年代流行于美国的西部影片,现在象征毁灭性遭遇,也可用来比喻人们对罪恶现象的责任感。brain bust原为由高级专家和大学教授组成的帮助富兰克林·罗斯福总统制定新政的智囊团,现指各种部门特聘的参与决策的智囊人物,有时也指才华出众的学生。
        除此之外,在新闻标题和紧接着的新闻内容里,常常使用或借用形象的词汇、日常用语以及口语、俚语等,以增加新闻报道的形象性、亲切感和吸引力。例如:
        The Second World War was another huge Volkermanderung,it was accompanied by a vast dislocation of people.第二次世界大战又是一次大规模的“民族迁移”,随之而来的是千千万万人的流离失所。Volkermanderung 是德语,意为“民族迁移”。
2.新闻英语的语法特点
        用一般现在时表达过去发生的事情。通常情况下,新闻报道所报道的消息多为已发生的事实,按照英语语法,动词应使用过去时。但新闻是新近发生的事实,为增强新闻报道的新鲜感(freshness)、现实感(reality)和直接感(immediacy),在新闻报道中一般不用过去时、过去完成时等,而采用现在时态,从形式上可以使读者在阅读时如置身于新闻事件之中。例如:Carter Picks New Envoy to Mexico卡特选出派往墨西哥的新特使。
        用不定式表达将来发生的事情。英文新闻标题中表示将来时的形式除一般将来时“will+动词原形”外,更多的还是采用“联系动词be+动词不定式”结构,其中联系动词be通常省略,以节省标题字数。例如:Pope to Visit Japan in February = Pope is to visit Japan in February教皇拟于二月访日。
        用现在分词表达正在进行的动作或正在发生的事态。对于正在发生的事态或动作,英文新闻标题按正常英语语法规则处理,采用现在进行时“be+现在分词”的形式,但“be”通常省略。因此,现在分词便在新闻标题中直接表示正在进行的动作或正在发展的事态。例如:Bill Gates Working on a New Book = Bill Gates is working on a new book比尔·盖茨撰写新书科技先锋展望未来。
3.新闻英语的句法特点
        时态呼应灵活。新闻报道中动词时态简化,有时不受时态应保持一致或呼应的语法规定,有较大的灵活性。例如:
        But Carter told reporters, the United States will continue the restraints it imposed on Iran when the hostages were taken 150 days ago……He made it clear, however, that the freezing of Iranian assets and monitoring of Iranian students in this country would continue. We will continue to monitor the situation very closely, “Carter said”.
        句中既有按传统语法规则呼应的“made ……would continue”,也有从实际出发灵活运用的“told……will continue”。
        句式多样弹性化。新闻英语中的句式富于变化。在新闻报道中有倒装句、省略句,有借助副词、动词变化的句式。例如:
        Says Dary Reading of Gowrie:“It makes you mad ,We are good at what we do ,but we still can't make a living.”
        高瑞的达里·雷丁说:“这使你发疯。我们有本领干好我们的工作,但仍不能谋生。”
        句中的谓语says位于句首,这种句式是新闻报道文章所特有的。
        被动语态的使用。当读者在广泛接触英语新闻之后,就会发现新闻标题使用主动语态的频率远远超过被动语态。这是因为从修辞学角度而言,主动语态比被动语态更加生动且富有感染力,所表达的意义更为直接,或更具有说服力,使读者感到真实可信,读来朗朗上口。但新闻报道中有时动作的接受者往往是读者关心的中心,比如有关灾难、战争、事故、骚乱等报道中,读者更关心的是伤亡人员与人数。因此,新闻英语有时为突出动作的承受者通常采用被动语态,目的在于抓住读者的注意力。我们来看下面的例子:
        A:“500 Reported Killed in S. Korean Building Collapse”
        B:“Building collapse claims 500 lives in S. Korea”
        这是一则报道韩国某百货大楼倒塌致使500人丧生的一条新闻。作为新闻报道,A或 B两条标题都起到了提示与浓缩内容的作用。但在报道中死亡人数是该新闻一个非常重要的内容。前句为被动语态,以数词开始,突出了死亡人数,使它处于醒目的位置,起到了吸引读者的作用,从而激发起读者的阅读兴趣和欲望,以探究其事故缘由。
        讲究修辞效果。新闻除了注重事实真实、表达清晰外,还讲究语言的美感和韵味。因此,常常借助于比喻、夸张、双关语、成语、押韵等修辞手法来增加新闻的可读性和吸引力。例如:
        All Work, Low Play Make Nurses Go Away工作辛苦,工资低廉,许多护士离职而去。(此句源自成语“All work and no play make John a dull boy”。)
        Dare Devil who dared胆大包天的人(通过押头韵和使用叠词来增加语言的节奏感,起到强调作用)。
        Are the Democrat Dinosaurs?民主党成了恐龙吗?
        这一标题运用比喻手法,把民主党比作恐龙(一种生活在中生代时期庞大的食肉或食草爬行类动物,现已绝种),寓意深刻。此文章写于共和党总统候选人罗纳德·里根在1980年获选总统之后,讽刺民主党在富兰克林·罗斯福和约翰·肯尼迪总统的光荣历史之后,气势变得十分微弱,令人可怜。
        Where there's smoke, there's cash (The Economist, 1996)有烟才有钱
        这一标题中运用了模仿(parody)的修辞手法,套用了英语谚语“Where there' s reek, there' s heat”(无风不起浪,有果必有因),借以讽刺美国的利益集团政治。香烟在美国几乎人人喊打,却总打不倒,因为政客们需要烟草商们的政治捐款,而后又利用手中的权力照顾烟草商们的利益。

The European commission has unveiled a "digital green certificate" that could allow EU citizens who have been vaccinated, tested negative or recovered from Covid-19 to travel more freely this summer.
The plan would also allow southern states such as Spain, Greece and Portugal, whose economies are most reliant on tourism, to make bilateral arrangements with non-EU members – including Britain – providing the deals are approved by the commission."We aim to help member states reinstate the freedom of movement in a safe, responsible and trusted manner,” the European commission president, Ursula von der Leyen, said as the scheme was unveiled on Wednesday,which was actively promoted by southern European holiday destinations whose economies have been devastated by the pandemic.
The digital document, containing a QR code and carried on a mobile phone, has deliberately not been called a "vaccine passport" because some member states felt that would discriminate against those who had not yet been offered a shot.
The certificate is "not a passport ... but a document that will describe the medical situation of the individuals who hold it", the commission spokesman, Eric Mamer, said.The certificate, should mean travellers will not need to quarantine(检疫,隔离) would be available to all citizens who can provide evidence that they have either been vaccinated against Covid-19, have recently tested negative, or have acquired antibodies after recovering from the virus.
The EU aims to vaccinate three-quarters of its adult population by the end of summer and officials remain hopeful that if national delivery speeds up, many restrictions could be lifted in time for the holidays.
1. What does the underlined word “reinstate” in paragraph 2 refer to?
A. Recover. B. Contain.
C. Adopt. D. Desire.
2. Why did southern European holiday destinations strongly support the plan?
A. Because their economies hardly depend on tourism.
B. Because travellers will not need to quarantine in any country.
C. Because they hope to promote economic recovery.
D. Because the European commission has unveiled the scheme.
3. Who can get a “digital green certificate”according to the commission?
A. Any EU citizen. B. A citizen vaccinated.

You’ve heard that plastic is polluting the oceans — between 4.8 and 12.7 million tonnes enter ocean ecosystems every year. But does one plastic straw or cup really make a difference? Artist Benjamin Von Wong wants you to know that it does. He builds massive sculptures out of plastic garbage, forcing viewers to re-examine their relationship to single-use plastic products.
At the beginning of the year, the artist built a piece called “Strawpocalypse,” a pair of 10-foot-tall plastic waves, frozen mid-crash. Made of 168,000 plastic straws collected from several volunteer beach cleanups, the sculpture made its first appearance at the Estella Place shopping center in Ho Chi Minh City, Vietnam.
Just 9% of global plastic waste is recycled. Plastic straws are by no means the biggest source（来源）of plastic pollution, but they’ve recently come under fire because most people don’t need them to drink with and, because of their small size and weight, they cannot be recycled. Every straw that’s part of Von Wong’s artwork likely came from a drink that someone used for only a few minutes. Once the drink is gone, the straw will take centuries to disappear.
In a piece from 2018, Von Wong wanted to illustrate（说明） a specific statistic: Every 60 seconds, a truckload’s worth of plastic enters the ocean. For this work, titled “Truckload of Plastic,” Von Wong and a group of volunteers collected more than 10,000 pieces of plastic, which were then tied together to look like they’d been dumped（倾倒） from a truck all at once.
Von Wong hopes that his work will also help pressure big companies to reduce their plastic footprint.
9. What are Von Wong’s artworks intended for?
A. Beautifying the city he lives in. B. Introducing eco-friendly products.
C. Drawing public attention to plastic waste. D. Reducing garbage on the beach.
10. Why does the author discuss plastic straws in paragraph 3?
A. To show the difficulty of their recycling.
B. To explain why they are useful.
C. To voice his views on modern art.
D. To find a substitute for them.
11. What effect would “Truckload of Plastic” have on viewers?
A. Calming. B. Disturbing.
C. Refreshing. D. Challenging.
12. Which of the following can be the best title for the text?
A. Artists’ Opinions on Plastic Safety
B. Media Interest in Contemporary Art
C. Responsibility Demanded of Big Companies
D. Ocean Plastics Transformed into Sculptures

One after another telecommunications giants have announced their latest fifth generation (5G) products. They have also claimed that 5G technology would be used on a massive scale by 2020. Yet, when reporting about 5G, many domestic media have described it as a"much faster" technology than 4G without mentioning any of its other advantages. As a result. the common public view about 5G is that they could "download a HD movie within one second". Beyond that, most people know nothing about 5G.
Actually, 5G technology has many more advantages than 4G apart from speed. According to the criteria of 3GPP, an international standardization organization, 5G technology can be used for at least three purposes—connecting everything, reliability of connections, and eliminating delays.
“Connecting everything” is an appropriate slogan for 5G technology, without which the Internet of Things would be impossible. 5G would enable one server to connect to multiple terminals, and thus establish high-speed coordination among them, and help the chips inside the terminals timely react to meet people’s needs. Take autonomous vehicles for example, they are mature technology products. Self-driving cars combine a variety of sensors, such as radar, computer vision, and GPS to identify navigation paths and obstacles. 5G technology will link all the elements of a transportation system, such as traffic lights, cameras and, of course, cars to establish perfect coordination so they can avoid obstacles and move on navigation paths, which will help strengthen self-driving technology.
Reliability of connections is another essential characteristic of 5G technology, whose use can be extended to other fields where high safety standards are required. For instance, in certain surgeries, surgeons insert nano-robots inside a patient’s body and have to maintain constant control over the robots to ensure they perform their functions and do not cause any harm to the patient. This is a technology that can be of great help, as it can establish reliable and continuous connections between the monitor and the nano-robots.
13. Which of the following can serve as an example of "connecting everything"?
A. Improvement of smart phone signals. B. Decrease in telecommunication cost.
C. High speed in playing computer games. D. Online tests for all members at the same time.
14. Why can 5G be used in the fields with high safety standards?
A. It can attract most eyeballs on a massive scale.
B. It can provide dependable and constant service.
C. It offers massive machine types of communication.
D. It employs 4G base stations and occupies less space.
15. What will the author most probably discuss in the following paragraph?
A. Eliminating delays. B. 5G network capacity
C. Disadvantages of 5G D. Building 5G base stations
16. What would be the best title for the passage?
A. 5G Technology: More than about High Speed
B. 5G Technology Will Shape the Future of Connectivity
C. Telecom Giants Work Together to Better 5G Technology
D. Advantages and Disadvantages of 5G Technology and Products

A study shows that the more eco-conscious way to shop is going to a physical store rather than by making purchases online from companies that don't have physical stores. Researchers estimated that shopping at physical stores for frequently bought items such as toilet paper, shampoo and toothpaste, often results in less greenhouse gas emissions than ordering the products from a company that only sells through the Internet.
The main reason is because of how people shop online： Many buy items online frequently — but they only buy a few items per purchase. Frequent online purchases produce more packaging waste, and online items tend to come from different distribution centers. Both factors result in higher greenhouse gas emissions per item.
The team modeled their research on the movement of goods from the factory all the way through to the end consumer. They analyzed the carbon footprint of the "last mile delivery" for the three most popular types of shopping channels in the United Kingdom — physical stores, "brick & clicks" (when people order online and a physical store delivers the items to them) , and "pure players” (strictly online sellers). Included in the three models were greenhouse gas emissions estimates from the number of products bought, transportation, warehouse storage , delivery and packaging activities.
The analysis showed that total greenhouse gas footprints per item purchased were higher from physical stores than those from bricks & clicks purchases in 63% of the shopping events but lower than those of pure players in 81 % of shopping events in the United Kingdom. In the United States, greenhouse gas emissions from shopping at physical stores were also estimated to be higher than from the brick & click channel, and lower than the pure play channel, on average.
This pattern holds true in countries where people mostly drive. It really depends on the country and consumer behavior there.
17. What is the function of the first paragraph?
A. To persuade the readers. B. To show the research conclusion.
C. To compare two shopping ways. D. To state the reason for this study.
18. Which is one of the disadvantages of frequent online shopping?
A. It is not convenient. B. It is a waste of money.
C. It causes packaging waste. D. It results in air pollution.
19. How is this research conducted?
A. By making comparison. B. By doing experiments.
C. By giving an explanation. D. By making a survey.
20. Which way of shopping might the author advocate?
A. Shopping by car. B. Buying in physical stores.
C. Dealing with “pure players". D. Purchasing from "brick & click.

It looked just like another aircraft from the outside. The pilot told his young passengers that it was built in 1964, a Boeing KC-135 refuelling tanker, based on the 707. But appearances were deceptive, and the 13 students from Europe and USA who boarded the aircraft were in for the flight of their lives.
For 12 months, science students from across the continents had competed to win a place on the flight at the invitation of the European Space Agency. The challenge had been to suggest imaginative experiments to be conducted in weightless conditions.
For the next two hours the Boeings flight resembled that of an enormous bird which had lost its reason, shooting upwards towards the heavens before moving down towards Earth. The intention was to achieve weightlessness for a few seconds.
The aircraft took off smoothly enough, but any feelings that I and the young scientists had that we were on anything like a scheduled passenger service were quickly dismissed when the pilot put the plane into a 45-degree climb which lasted around 20 seconds. Then the engines cut out and we became weightless. Everything became confused, and left or right, up or down no longer had any meaning. After ten seconds of free-fall descent (下降) the pilot pulled aircraft out of its nosedive. The return of gravity was less immediate than its loss, but it was still sudden enough to ensure that some students came down with a bump.
Each time the pilot cut the engines and we became weightless, a new team conducted its experiment. First it was the Dutch, who wanted to discover why cats always land on their feet. Then it was the German team, who conducted a successful experiment on a traditional building method to see if it could be used for building a future space station. The Americans had an idea to create solar sails that could be used by satellites.
After two hours of going up and down in the plane doing experiments, the dominant feeling was one of excitement rather than sickness. Most of the students thought it was an unforgettable experience and one that would be keen to repeat.
21. What did the pilot do with the plane?
A. He climbed and then made the plane fall slowly.
B. He climbed and then made the plane turn over.
C. He quickly climbed and then stopped the engines.
D. He took off normally and then cut the engines for 20 seconds.
22. What was the point of being weightless?
A. To show the judges of the competition what they could do.
B. To prepare the young scientists for future work in space.
C. To see what conditions are like in space.
D. To allow the teams to try out their ideas.
23. The pronoun “it” (in the last paragraph) refers to ________.
A. the excitement B. the trip
C. the opportunity D. the plane
24. The passage is intended to ________.
A. report on a new scientific technique
B. encourage young people to take science
C. show scientists what young people can do
D. describe the outcome of a scientific competition

Cities such as New York, Washington, Boston and San Francisco have launched bike-share programs to ease traffic jam, improve public health, and cut carbon emissions (排放). Cyclists in those cities tend to choose bike-sharing to make their trips to office or home faster, cheaper, and more fun. Last year, U.S. bike-share riders completed nearly 46 million trips—more than twice as many trips from the previous year.
Yet despite these programs’ advantages and popularity, there are still huge challenges. Take, for instance, the distribution (分布) of bikes. The living area face shortages of bicycles in the morning rush, while business districts do not have enough bikes in the evening. What’s more, parking places can be full at certain hours, making it difficult for riders to return the bikes once they’ve reached their destinations.
Solving this problem is not easy. David B. Shmoys and his colleagues set out to develop complex algorithms(算法) and advanced analytics(逻辑法) to solve the challenges of bike-share operations.
One area in which the methods were applied was the Bike Angels program. As part of the program, cyclists can be rewarded with points by renting or returning bikes at certain high-need stations. Today, Bike Angels accounts for roughly 30 percent of bike rebalancing in New York City. It has greatly improved customer satisfaction which, in turn, has more riders. And more importantly, this form of rebalancing comes with a much less carbon emissions, because less box trucks are needed to move the bikes!
David B. Shmoys and his colleagues applied algorithms and analytics to solve other problems, too. However, they can not solve every new transportation problem. They have many limitations, including incomplete information. That is, David B. Shmoys and his colleagues only observe the realized rentals (returns) at stations at which bikes were available, not those that were blocked due to the imbalance of the system.
25. Which is not one of the advantages of bike-share program?
A. It helps people save money.
B. It helps improve the air quality.
C. It provides more bikes for cyclists.
D. It helps people build up their bodies.
26. What is mainly talked about in paragraph 2?
A. Riders do not want to return the bikes.
B. The distribution of bikes is a big problem.
C. People do not have enough bikes in the morning.
D. The bike-share program is very popular in New York.
27. What do we know about the Bike Angels program?
A. It had more users due to the algorithms.
B. It increased the use of box trucks.
C. It awarded riders cash for renting bikes.
D. It re-balanced all the bikes in New York.
28. What does the underlined word “they” in the last paragraph probably refer to?
A. other problems
B. carbon emissions
C. algorithms and analytics
D. Transportation problems

According to a survey published by the American Institutes for Research last year, a total of 57 colleges were operating some form of CBE programs and about 85 percent of all the higher education officials said they were either designing a CBE program at their school or were considering doing so.
Students in a CBE program choose a central field of study, just as they would at a traditional college or university. Yet instead of attending a series of classes led by professors or teaching assistants at schools, the students study online and direct themselves.
CBE programs require students to show their understanding of a given set of sills Students must prove their mastery of skills that relate to their field of choice by taking related exams. Once they have met all the requirements of their study programs, the students will get their degrees.
CBE programs have made use of many new technologies, especially internet and online media. This helps reduce barriers for nontraditional and other students by bringing higher education to them. And programs that permit students to work at their own speed may save students' money by reducing the time it takes for them to earn a degree.
But some educators have concerns about the value of the education that CBE programs offer. Johann Neem at Western Washington University argues that the purpose of higher education is not simply to help students master certain skills. It should teach students how to think critically (批判性地) understand the subjects they are studying more deeply and see how they are connected to other subjects. Only that way can they put the knowledge to better use.
He said, “You need to explore, think .. get shaken, have a conversation and struggle. And those things take time.”
Instead of supporting CBE, he adds, policy makers and educators should look for ways to improve access and reduce costs for traditional higher education.
29. How are CBE programs different from traditional college education?
A. They require students to choose their subjects.
B. They offer shorter curricula and are less expensive.
C. They heavily rely on the information technologies.
D. They allow students to take easier examinations.
30. What can we learn from Johann Neem's words?
A. Free access to traditional education should be provided.
B. Higher education just focuses on critical thinking skills.
C. Students should spend longer time completing the degree courses.
D. College students should be challenged to explore around their subjects.
31. How does Johann Neem's attitude toward CBE programs?
A. Supportive. B. Disapproving.
C. Sympathetic. D. Uncaring.
32. What is the author's purpose in writing the text?
A. To press policy-makers to provide more affordable education.
B. To show the disadvantages of the traditional college education.
C. To introduce a new controversial trend in the higher education.
D. To encourage educators to improve the quality of CBE programs.

It is commonly believed that all over the world, boys and girls attend a mixed school, where they study together. But boys' schools are the perfect place to teach young men to express their emotions and involve them in activities such as art, dance and music.
Always boys at single-sex schools were said to be more likely to get involved in cultural and artistic activities that helped develop their emotional expressiveness, rather than feeling they had to correspond to(和…相符) the "boy code" of hiding their emotions to be a "real man".
Surprisingly, the findings of the study go against received wisdom that boys do better when taught alongside girls.
George Carl, headmaster of Eton, warned that boys were being failed by the British education system because it had become too focused on girls. He criticized teachers for failing to recognize that boys are actually more emotional than girls.
The research argued that boys often perform badly in mixed schools because they become discouraged when girls do better earlier in speaking and reading skills.
But in single-sex schools teachers can adjust lessons to boys' learning style, letting them move around the classroom and getting them to compete in teams to prevent boredom, wrote the study's author, Abigail James, of the University of Virginia.
Teachers could encourage boys to enjoy reading and writing with "boy-focused" approaches such as themes and characters that appeal to them. Because boys generally have moreacutevision, learn best through touch, and are physically more active, they need to be given "hands-on" lessons where they are allowed to walk around. "Boys in mixed schools view classical music as feminine(女性的) and prefer the modern genre (类型) in which violence and sexism are major themes," James wrote.
Single-sex education also made it less likely that boys would feel that they had to be "masterful and in charge" in relationships. "In mixed schools, boys feel forced to act like men before they understand themselves well enough to know what that means," the study reported.
33. The writer argues that a single-sex school would ________.
A. encourage boys to express their emotions more freely
B. help boys to be more competitive in schools.
C. force boys to he their emotions to be "real men".
D. naturally strengthen boys’ traditional image of a man.
34. Traditionally, in a mixed school boys ________.
A. behave more responsibly
B. perform relatively better
C. grow up more healthily
D. receive a better education
35. In Abigail James’ opinion, one of the advantages of single-sex schools is ________.
A. boys can choose to learn whatever they are interested in
B. boys can focus on their lessons without being distracted
C. teaching can be adjusted to suiting the characteristics of boys
D. teaching can be designed to promote boys' team spirit
