23、phones nearby.BIt was a reading class. While all her classmates were flying through the 2nd and 3rd books in the Harry Potter series, Skye Malik, only on page four of the first book, got impossibly stuck on the word “doughnut”.Her unexpected difficulty with reading is called dyslexia. Skye got a pro
24、fessional diagnosis at the end of the 2nd grade. Knowing that other kids were going through the same thing made it easier on her somehow. What wasnt easy, even after all the help she got from special tutors and reading programs, was fluent reading. What many people do without thinkingreadingshe had
25、to struggle with word by word, sometimes letter by letter. In class, she would hear the other kids flip through the pages on assignments and go on to the questions while she was still doing battle with the first paragraph.She was as frustrated as she was discouraged. But she didnt know of any other
26、way until her 4th grade teacher, Miss Pollock, told her about something called Learning Ally.Learning Ally is a non-profit organization that offers audio versions of books. A crew of volunteer readers has recorded 75,000 classic novels, childrens books, and school textbooks that help more than 300,0
27、00 students and adults with learning differences or who are blind. Now Skye could listen to the books with her ears and follow the words with her eyes on the page. Instead of having her mother read her textbooks to her, she could independently do her work. “With Learning Ally, I feel confident and c
28、apable and can easily keep up with my classmates,” Skye explains, “and I want other kids to feel empowered, just the way I did.”So Skye, now aged 16, created The Paco Project which was named after her grandfather whose nickname was “Paco”. The Paco Project is a fundraiser and educational initiative
29、focusing on giving students with dyslexia access to the same Learning Ally technology that changed her life.Skye has realized that she is one of the lucky kids who have been diagnosed. She knows that educating teachers about dyslexia and giving students with the learning challenge the tools they nee
30、d is a great first step in meeting dyslexia head on and helping them be confident, capable students.“Right now they feel stuck ashamed, unsure and insecure about their school work. If I could help stop these students feeling this way, that would mean the world to me.”24. According to the passage, Sk
31、ye _.A. found a way out with the help of Miss PollockB. felt annoyed at being teased by her classmatesC. preferred reading the first book of Harry PotterD. was diagnosed with dyslexia in her fourth grade25. The Paco Project was created _.A. to promote Learning Ally technologyB. to empower those with
32、 reading difficultyC. with inspiration from Skye5s grandfatherD. in response to the growing demands of teachers26. The passage is mainly about _.A. what people with dyslexia are sufferingB. what measures are needed to beat dyslexiaC. how Learning Ally influenced people with dyslexiaD. how Skye battl
33、ed against dyslexia and helped othersCThe philosopher, Martin Buber, is most known for his work on “I-Thou/You” relationships in which people are open, direct, mutually interested in each other. In contrast, “I-It” relationships are those in which we use the other, like an object, to solve our probl
34、ems and fulfill our needs and purposes.It is not our fault that many of our relationships are or become “It” relationships because most of what we feel, think and do is motivated by unconscious memories of how to survive the environment into which we were born. Thus, one of the reasons we use other
35、people to help us feel better about ourselves and cope in the world is that using people was once necessary and it worked. When we were small and helpless, “It” came and fed us, and held us, and set us on our way. We didnt have to reciprocate and care for “It”. Even when the care and attention of “I
36、t” was minimal or unpredictable, if we got out of childhood alive, somewhere along the way “It” was involved.Freud called this stage of early life “primary narcissism”, which is our instinct (本能) for self-preservation and is a normal part of our development. While most of us grow out of it，we still
37、hold a survival fear, which motivates us to escape danger and to stay alive, and we all need this fear in healthy measure.The problem is that too many of us, too much of the time, are in a constant state of threatand we often dont know it. We imagine people are talking about us behind our backs, tha
38、t we have cancer, that we are inadequate, and vulnerable to more than our share of bad luck. As our brains have grown in size and complexity, so has our ability to scare ourselves.This causes many problems. For example, our stress levels increase, our digestion is impaired and our thinking becomes r
39、estricted. Our threat response stops any bodily function, feeling, thought and behavior that might “waste” energy and detract from fighting or escaping danger. Thus, when in threat, our emotional, cognitive and behavioral range is significantly reduced.And in this reduced state, one of our solutions
40、 is to find someone who can save and comfort us. Instead of enabling us to be open, direct and mutual, fear and anxiety lead us towards conversations and choices in our relations with others that are orientated towards survivingnot thriving (茁壮成长). Threat-motivated relationships are characterized by
41、 need, dependency, control, demand, dishonesty, and self-interest.We cannot form the “I-Thou” relationships that Buber speaks of until we have learned to notice, comfort, and understand the emotions and patterns of our threat brain. When in threat, we tend to use other people as objects who can save
42、 and protect us, or who we can blame for our problems.27. What does the underlined word “reciprocate” in Paragraph 2 probably mean?A. Return the favour.B. Ask for some advice.C. Convey an apology.D. Make some comments.28. What can we learn about “primary narcissism”?A. It leads to our survival fear.
43、B. It is normal and usually temporary.C. It impacts our growth negatively.D. It lays the foundation for Freuds theory.29. Which of the following could be an example of “I-It” relationships?A. Comforting an upset friend.B. Feeling sorry for your mistakes.C. Trying hard to be independent.D. Asking oth
44、ers to take on your task.30. What would be the best title for this passage?A. How We Can Form the “I-Thou” RelationshipsB. How We Can Get Out of the “I-It” RelationshipsC. Why We Treat Others as Objects Rather Than IndividualsD. What Helps Us Survive and Thrive in Early Stages of LifeDMove Over, Sel
45、fish GeneEvolution traditionally has a problem with nice people. If only the fittest individuals survive, then those who are nice to others at their own expense will surely be weeded out. Yet cooperation is widespread in nature, from plants alerting each other to danger to dolphins cooperating to ro
46、und up fish.A decades-old idea called kin selection can explain some of this: if organisms (生物) have enough DNA in common, then they can further their own selfish genes by helping one another. Bees and ants have a system of reproduction which leaves colony members so closely related that they act al
47、most as a single super-organism. And among any sexually reproducing species, parental care helps individuals pass on their genes.But kin selection cannot explain why humans are so nice to strangers. One idea is that we have evolved to be super-cooperative because, over time, more cooperative groups
48、have outcompeted less cooperative ones. But there generally isnt enough genetic variation between groups to allow natural selection to favor more cooperative ones.Some researchers think the solution lies in an idea called cultural group selection. Forget shared genes, they argue. Selection can favor
49、 cooperative groups if the people within them share enough culture. The idea is controversial because to work it requires that groups remain culturally distinct. As critics point out, people tend to migrate (迁移) between groups, which should homogenize (使同质化) ideas and customs. Those who back the con
50、cept counter that groups have ways to maintain their distinct culture, including a process called norm (准则) enforcement. Put simply, if someone migrates into a new cultural group, they are pressured into following the local rules because failing to do so leads to punishment.Earlier this year, Mathew
51、 and Handley at Arizona State University published a study testing the idea. They sampled 759 people from four ethnic groups in Kenya who compete intensively for land, water and livestock. The pair estimated that genetic differences between individuals from different groups was generally less than 1
52、5%. Cultural practices and beliefs varied much more, by 10% to 20%. People cooperated most with members of their own group, as cultural group selection predicts, and to a lesser extent with members of other groups whose norms most closely matched their own. That makes sense if culture rather than ge
53、netics is what matters. “I think this is one of the most explicit tests of cultural group selection theory so far,” says Mathew.Not everyone is persuaded. Krasnow at Harvard University sees no theoretical flaw with the idea, but says that some of his research undermines it. He has found that people
54、dont just enforce the rules within their group, but also punish people from other groups who fail to follow their own groups norms. Mathew counters that it is reasonable to enforce the norms on outsiders as a step towards incorporating (使并入) them into your cultural group. “This is often how empires
55、expand,” she says.31. The example of bees and ants is used to _.A. highlight the significant role of reproductionB. demonstrate the efficiency of a super-organismC. reveal why parents care about their selfish genesD. explain the cause of organisms helping one another32. For the idea of cultural grou
56、p selection to work, a pre-condition is that _.A. cooperative groups have a larger chance of survivalB. genetic variations in the same cultural group are smallC. cultural differences are weakened with people migratingD. cultural distinctiveness can be preserved with certain methods33. The text is de
57、veloped mainly through _.A. sorting information into different topicsB. narrating events in time orderC. presenting doubts and exploring answersD. discussing similarities and differences34. We can learn from the passage that _.A. culture plays a more significant role in choosing cooperatorsB. being
58、selfish is of vital importance for an individual to surviveC. Mathews study result contradicts what cultural group selection predictsD. people joining a new group will be punished for not keeping their own culture第二节（共5小题；每小题2分，共10分）根据短文内容，从短文后的七个选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。The Changing Landscape o
59、f the Music BusinessThe music industry is in the process of a great change. In the past decades artists made money through physical sales of records, CDs, and cassettes. While in recent years, downloading songs from services such as Amazon or iTunes has become the most common way for people to purch
60、ase music, and the whole idea of buying music to own may be falling. To take its place are Internet apps that stream music directly to listeners on their smartphones, tablets, or computers._35_While this is great for fans, who now have access to millions of songs at the flick of a touchscreen, it ha
61、s shattered the traditional model of how an artist manages his or her career.With music lovers increasingly moving away from making one-time purchases towards an all-you-can-listen-to service, what is a hard-working artist to do? The main problem facing many musicians is that payments-per-stream of
62、a song are much lower than what an artist would receive from a download. _36_In November of 2014, award-winning musician Taylor Swift pulled her entire music catalog from Spotify, a popular streaming app, claiming that their business model suggests that music does not hold much worth._37_They claim
63、that it offers smaller artists a chance for their music to get heard by a wider audience. Brian Message, manager of the band Radiohead, has come out in support of streaming services. He sees them as a way for musicians and fans to interact.Regardless of what artists may think about this change in th
64、e music industry, theres no arguing that they need to adapt in order to make money._38_Corporate sponsorship can be a risky option for musicians. A band can make much money by agreeing to promote a product or license its music for use in advertisements, but there are many ways that this can backfire
65、. When bands work with businesses, they may lose the image they have worked to create._39_Artists must develop an image that appeals to their fans in order to remain unique and authentic, or they risk striking .the wrong chord, which could leave them struggling to sustain careers in this new busines
66、s landscape.A. Others have welcomed the idea of streaming musicB. However, those forms of media are quickly fading away.C. Some big-name artists have called attention to the issue.D. The rules could be different for smaller bands just starting outE. Maintaining a fine image while working on a career

68、ion has allowed a new type of teacher to emergean artificial one. But just how accepting students are of an artificial instructor remains to be seen. Thats why researchers at the University of Central Floridas Nicholson School of Communication and Media are working to examine student perceptions of
69、AI-based teachers. Some of their findings, published recently in the International Journal of Human-Computer Interaction, indicate that for students to accept an AI teaching assistant, it needs to be effective and easy to talk to.According to Jihyun Kim, the lead author of the study, the hope is tha
70、t by understanding how students relate to Al-teachers, engineers and computer scientists can design them to easily integrate into the education experience.“To use machine teachers effectively, we need to understand students views on machine teachers, their learning experiences with them and more,” K
71、im says. “This line of research is needed to design effective machine teachers that can actually facilitate positive learning experiences.”AI teaching assistants can help ease a teachers workload, such as by responding to commonly asked questions by students. These questions, which often appear each
72、 semester and become numerous in online classes with hundreds of students, can become a large task for a teacher. The quick delivery of answers also helps students.An example of an AI teaching assistant is one named Jill Watson that was created by a researcher at the Georgia Institute of Technology.
73、 Jill was fed the thousands of questions and answers commonly asked in the researchers online class that hed taught over the years. With some additional learning and adjustments, Jill was eventually able to answer the students commonly asked questions accurately without any human assistance as if sh
74、e was one of the researchers human teaching assistants.“I hope our research findings help us find an effective way to incorporate AI agents into education,” Kim says. “By adopting an AI agent as an assistant for a simple and repetitive task, teachers would be able to have more things scheduled such
75、as meeting with students and developing teaching strategies.”40. What kind of AI teaching assistants can students easily accept?41. What do researchers need to do to design effective AI teaching assistants?42. Please decide which part is false in the following statement, then underline it and explai
76、n why.With the help of Al-based teaching assistants, human teachers can not only be relieved from heavy work but also have more time to answer commonly asked questions by students.43.

While all her classmates were flying through the 2nd and 3rd books in the Harry Potter series, Skye Malik, only on page four of the first book, got impossibly stuck on the word “doughnut”.Her unexpected d
101、ifficulty with reading is called dyslexia. Skye got a professional diagnosis at the end of the 2nd grade. Knowing that other kids were going through the same thing made it easier on her somehow. What wasnt easy, even after all the help she got from special tutors and reading programs, was fluent rea
102、ding. What many people do without thinkingreadingshe had to struggle with word by word, sometimes letter by letter. In class, she would hear the other kids flip through the pages on assignments and go on to the questions while she was still doing battle with the first paragraph.She was as frustrated
103、 as she was discouraged. But she didnt know of any other way until her 4th grade teacher, Miss Pollock, told her about something called Learning Ally.Learning Ally is a non-profit organization that offers audio versions of books. A crew of volunteer readers has recorded 75,000 classic novels, childr
104、ens books, and school textbooks that help more than 300,000 students and adults with learning differences or who are blind. Now Skye could listen to the books with her ears and follow the words with her eyes on the page. Instead of having her mother read her textbooks to her, she could independently
105、 do her work. “With Learning Ally, I feel confident and capable and can easily keep up with my classmates,” Skye explains, “and I want other kids to feel empowered, just the way I did.”So Skye, now aged 16, created The Paco Project which was named after her grandfather whose nickname was “Paco”. The
106、 Paco Project is a fundraiser and educational initiative focusing on giving students with dyslexia access to the same Learning Ally technology that changed her life.Skye has realized that she is one of the lucky kids who have been diagnosed. She knows that educating teachers about dyslexia and givin
107、g students with the learning challenge the tools they need is a great first step in meeting dyslexia head on and helping them be confident, capable students.“Right now they feel stuck ashamed, unsure and insecure about their school work.

110、ing Ally influenced people with dyslexiaD. how Skye battled against dyslexia and helped others【答案】24. A 25. B 26. DCThe philosopher, Martin Buber, is most known for his work on “I-Thou/You” relationships in which people are open, direct, mutually interested in each other. In contrast, “I-It” relatio
111、nships are those in which we use the other, like an object, to solve our problems and fulfill our needs and purposes.It is not our fault that many of our relationships are or become “It” relationships because most of what we feel, think and do is motivated by unconscious memories of how to survive t
112、he environment into which we were born. Thus, one of the reasons we use other people to help us feel better about ourselves and cope in the world is that using people was once necessary and it worked. When we were small and helpless, “It” came and fed us, and held us, and set us on our way. We didnt
113、 have to reciprocate and care for “It”. Even when the care and attention of “It” was minimal or unpredictable, if we got out of childhood alive, somewhere along the way “It” was involved.Freud called this stage of early life “primary narcissism”, which is our instinct (本能) for self-preservation and
114、is a normal part of our development. While most of us grow out of it，we still hold a survival fear, which motivates us to escape danger and to stay alive, and we all need this fear in healthy measure.The problem is that too many of us, too much of the time, are in a constant state of threatand we of
115、ten dont know it. We imagine people are talking about us behind our backs, that we have cancer, that we are inadequate, and vulnerable to more than our share of bad luck. As our brains have grown in size and complexity, so has our ability to scare ourselves.This causes many problems. For example, ou
116、r stress levels increase, our digestion is impaired and our thinking becomes restricted. Our threat response stops any bodily function, feeling, thought and behavior that might “waste” energy and detract from fighting or escaping danger. Thus, when in threat, our emotional, cognitive and behavioral
117、range is significantly reduced.And in this reduced state, one of our solutions is to find someone who can save and comfort us. Instead of enabling us to be open, direct and mutual, fear and anxiety lead us towards conversations and choices in our relations with others that are orientated towards sur
118、vivingnot thriving (茁壮成长). Threat-motivated relationships are characterized by need, dependency, control, demand, dishonesty, and self-interest.We cannot form the “I-Thou” relationships that Buber speaks of until we have learned to notice, comfort, and understand the emotions and patterns of our thr
119、eat brain. When in threat, we tend to use other people as objects who can save and protect us, or who we can blame for our problems.27. What does the underlined word “reciprocate” in Paragraph 2 probably mean?A. Return the favour.B. Ask for some advice.C. Convey an apology.D. Make some comments.28.
120、What can we learn about “primary narcissism”?A. It leads to our survival fear.B. It is normal and usually temporary.C. It impacts our growth negatively.D. It lays the foundation for Freuds theory.29. Which of the following could be an example of “I-It” relationships?A. Comforting an upset friend.B.
121、Feeling sorry for your mistakes.C. Trying hard to be independent.D. Asking others to take on your task.30. What would be the best title for this passage?A. How We Can Form the “I-Thou” RelationshipsB. How We Can Get Out of the “I-It” RelationshipsC. Why We Treat Others as Objects Rather Than Individ
122、ualsD. What Helps Us Survive and Thrive in Early Stages of Life【答案】27. A 28. B 29. D 30. CDMove Over, Selfish GeneEvolution traditionally has a problem with nice people. If only the fittest individuals survive, then those who are nice to others at their own expense will surely be weeded out. Yet coo
123、peration is widespread in nature, from plants alerting each other to danger to dolphins cooperating to round up fish.A decades-old idea called kin selection can explain some of this: if organisms (生物) have enough DNA in common, then they can further their own selfish genes by helping one another. Be
124、es and ants have a system of reproduction which leaves colony members so closely related that they act almost as a single super-organism. And among any sexually reproducing species, parental care helps individuals pass on their genes.But kin selection cannot explain why humans are so nice to strange
125、rs. One idea is that we have evolved to be super-cooperative because, over time, more cooperative groups have outcompeted less cooperative ones. But there generally isnt enough genetic variation between groups to allow natural selection to favor more cooperative ones.Some researchers think the solut
126、ion lies in an idea called cultural group selection. Forget shared genes, they argue. Selection can favor cooperative groups if the people within them share enough culture. The idea is controversial because to work it requires that groups remain culturally distinct. As critics point out, people tend
127、 to migrate (迁移) between groups, which should homogenize (使同质化) ideas and customs. Those who back the concept counter that groups have ways to maintain their distinct culture, including a process called norm (准则) enforcement. Put simply, if someone migrates into a new cultural group, they are pressu
128、red into following the local rules because failing to do so leads to punishment.Earlier this year, Mathew and Handley at Arizona State University published a study testing the idea. They sampled 759 people from four ethnic groups in Kenya who compete intensively for land, water and livestock. The pa
129、ir estimated that genetic differences between individuals from different groups was generally less than 15%. Cultural practices and beliefs varied much more, by 10% to 20%. People cooperated most with members of their own group, as cultural group selection predicts, and to a lesser extent with membe
130、rs of other groups whose norms most closely matched their own. That makes sense if culture rather than genetics is what matters. “I think this is one of the most explicit tests of cultural group selection theory so far,” says Mathew.Not everyone is persuaded. Krasnow at Harvard University sees no th
131、eoretical flaw with the idea, but says that some of his research undermines it. He has found that people dont just enforce the rules within their group, but also punish people from other groups who fail to follow their own groups norms. Mathew counters that it is reasonable to enforce the norms on o
132、utsiders as a step towards incorporating (使并入) them into your cultural group. “This is often how empires expand,” she says.31. The example of bees and ants is used to _.A. highlight the significant role of reproductionB. demonstrate the efficiency of a super-organismC. reveal why parents care about
133、their selfish genesD. explain the cause of organisms helping one another32. For the idea of cultural group selection to work, a pre-condition is that _.A. cooperative groups have a larger chance of survivalB. genetic variations in the same cultural group are smallC. cultural differences are weakened
134、 with people migratingD. cultural distinctiveness can be preserved with certain methods33. The text is developed mainly through _.A. sorting information into different topicsB. narrating events in time orderC. presenting doubts and exploring answersD. discussing similarities and differences34. We ca
