Little did he know that this challenge would lead to a wonderful friendship with 84-year-old Ms. Ann.Brennan’s promise to send his little attractive things every day for a week developed a habit of checking up on Ms. Ann and sending gifts regularly(定期地), long after the challenge was over.Their friendship has now lasted for over five years, and Brennan still visits Ms. Ann every month with flowers, cakes, chocolates, cards and more.They talk about everything from his high school life to his college goals. The pair has found that they share a common love of chocolates. Ms. Ann always hopes to hear about what he’s doing and loves to share her own stories from a different time. They have become the best friends, with Brennan treating her as his great-grandmother.Brennan’s mom, Traci, takes pride in her son. She said, “The best thing a teenager can do is to take care of the elderly. I’m so glad my son has added more sunshine to Ms. Ann’s life. I hope he always remembers the joy he’s brought her, and his fun talks with her, keeps his kind heart, and thinks of others.”Ms. Ann’s daughter Emma, with her husband Gould, has a 2-year-old son. They are thankful for Brennan’s friendship as they cannot always be with Ms. Ann. Brennan’s kind heart has brought more sunshine into Ms. Ann’s life, and her encouraging words have helped to inspire(启发)him in return.24．How did the task “Kindness Week Challenge” affect Brennan?A．He discovered his love of chocolates.B．He became a good friend of Ms. Ann.C．He developed a habit of receiving gifts.D．He learned how to choose attractive things.25．What do Brennan and Ms. Ann both like?A．Flowers.B．Cakes.C．Chocolates.D．Cards. 26．What makes Traci feel proud of Brennan?A．His kindness to others.B．His talent for telling stories.C．His good performances at school.D．His ability to earn money for the gifts.27．How do Ms. Ann’s family feel about Brennan?A．Worried.B．Sorry.C．Thankful.D．Surprised.Foreign visitors to the UK might be disappointed when they learn that not everyone there speaks like Harry Potter and his friends. Usually, there’s an assumption by many non-Brits that everyone in Britain speaks with an accent known as Received Pronunciation (RP, 标准发音), also called the “Queen’s English”. However, while many people do talk this way, most Britons speak with their own regional accents.Scouse, Glaswegian and Black Country dialect—from Liverpool, Glasgow and the West Midlands—are just three of the countless non-RP accents that British people speak with. There are even differences in accents between towns or cities just 30 kilometers apart. What is even more disappointing is that not speaking with the RP accent may mean a British person is judged and even treated differently in their everyday life.In a 2015 study by the University of South Wales, videos of a group of people reading a passage with three different UK accents were shown to a second group of people. The second group then rated how intelligent they thought the readers sounded. The lowest-rated accent was Brummie, spoken by people in Birmingham, a city whose accent is considered working-class.However, there is no need to be disappointed though you are not speaking with the RP accent. In fact, doing the opposite may even give you strengths.Kong Seong-jae is an Internet celebrity from Seoul. After studying in the UK, he picked up several regional accents. He’s now famous for his online videos, where he shows off the various accents he’s learnt. “British people usually get really excited when I use some of their local dialect words, and they become much friendlier. I think it makes a bond(联系)between local people and foreigners to speak with their local accent,” he said.So if you’re working on perfecting your British accent, try to speak like someone from Liverpool, Glasgow or Birmingham. You may not sound like Harry Potter, but you are likely to make more friends.28．What can we know from Paragraph 1?A．Non-Brits usually hold that all Britons speak with an accent called RP.B．Only the ”Queen’s English“ is accepted in the UK.C．Foreign visitors are disappointed at their own spoken English.D．All Britons speak with regional accents29．What do people think of the Brummie accent?A．It is favoured by foreign visitors to the UK.B．It is the closest to RPC．It sounds smart and is easy to understand.D．It is spoken by working class people.30．What does the underlined phrase “doing the opposite” in Paragraph 4 refer to?A．Speaking with the RP accent.B．Speaking with regional accents.C．Speaking with Brummie accent.D．Speaking like Harry Potter.31．What is the passage mainly about?A．A study of the most intelligent accent in Britain.B．A comparison between different British accents.C．How much British people value the RP accent.D．There are many regional accents in the UK besides RP.The thought of low material need and being unwilling to work, marry and have children, is described as a “lying down” lifestyle recently. It creates an emotional reaction among many young Chinese who are eager to take pause to breathe in this fast-paced and highly competitive society.Many young people complained to the Global Times that duties, including work stress, family argument and financial pressure, have pushed them “against the wall”. They said they hate the “involution (内卷)”, joking that they would rather give up some of what they have than get stuck in an endless competition against peers(同龄人).“Instead of always following the ‘good quality’ of struggle and sacrifice to bear the stresses, they prefer a temporary(暂时的) lying down as release and adjustment,” said an expert. “It is no wonder that some young people, under the growing pressures from child-raising to paying the mortgage (按揭) today, would try to live in a simple way and leave the worries behind.”Interestingly, the majority of young people, who claim to be big fans of the lying downphilosophy, admit that they only accept a temporary lying down as a short rest. It is true that with the great improvement of living conditions, some Chinese youth have partially lost the spirit of hardship and are not willing to bear too much hard work. But in fact, lying down is not entirely comfortable. Young people who lie down always feel ashamed about their constant loss of morale (士气).“Young people have both ambition and confusion about their future, but most of us have refused to waste opportunities and challenges,” a postgraduate student told the Global Times. “It’s no use running away. I have to ‘stand up’ and face the reality sooner or later.”32．Which of the following is NOT a “lying down” lifestyle according to the passage?A．Being uninterested in material enjoyment and refusing to shoulder duties.B．Being involved in various social activities.C．Stopping to breathe in a stressful life.D．Giving up struggle and sacrifice.33．What might have caused the “lying down” lifestyle among the young?A．Poor health from working so hard.B．Increasing material wealth from families.C．Growing pressure from family and social life.D．Temporary adjustment to failure in competitions.34．What’s the expert’s attitude toward the “lying down” group?A．Understanding.B．opposed C．Supportive.D．Unclear. 35．What can be inferred about the young generation from the text?A．They would rather escape than take challenges.B．They really enjoy the “lying down” lifestyle.C．They find their dreams far beyond their reach.D．They never really drop theirresponsibilities.三、七选五Stepping out of your comfort zone (区域) helps you to improve yourself and become a happy and fun person. You’ll experience greater enjoyment as you try out new experiences.uncomfortable at first, but you will know that is just part of the process to let you know better about yourself.Go to another countryYou will experience new cultures, different customs, unique landscapes and another language from travel. 38 . Additionally, the excitement of exploring different scenery and experiencing different cultures are lifelong treasure.39Try diving, skydiving or a roller coaster ride. If those are too frightening, try giving a speech or taking a dance class. Once you overcome your inner fear, you will have a sense of satisfaction that comes from overcoming it.Talk with someone newThis doesn’t have to be a complete stranger. Start a conversation with someone new at work, the barista (咖啡师) in your local coffee shop, a neighbour or someone in the queue.40 . By focusing on other people rather than your own internal thoughts, you can improve your own mental health.A．Do something that is fearful for youB．Become uncomfortable with the InternetC．You can end your conversation with your friends anytimeD．Leave your phone at home, turn off the TV and the InternetE．Here are some ways that can probably lead you to a new lifeF．See if you can continue the conversation for 30 seconds or longerG．Besides, using cash from different countries is also good for your brain四、完形填空writing?One day, it was too noisy and my thoughts were entirely disturbed. I had my husband go to 47 her about the matter. Minutes later, he returned. “That girl is only 17,” he48 with a sad look, “but she has bone cancer.” My mind suddenly went 49 . “Her mother said that the more hurtful it is, the louder her daughter sings. It helps her 50 the pain. The poor mother begs our pardon for interrupting us.” In a flash, I felt guilty about my thoughtless 51 .From that day on, I no longer felt anything wrong, and even got used to her singing—I felt as if 52 by the smell of flowers. Afterwards I was on business and happened to know the girl had been admitted into a hospital. When I returned home in late summer, I somehow felt that something was 53 . I couldn’t hear the girl next door sing anymore.“However hard the winds blow, you will stray ( 走失) no more from my 54 … You shall believe that I am brave only with you…” Her singing always 55 in my mind.

I 4 , “Is there anything else I’ve done wrong, but didn’t apologized for?”Again, his 5 was immediate, “Remember last Christmas when Mom said you had to go to the 6 because Stephen was going to be born? You left us at home and 7 in a hurry. Remem ber?”“Well, you left and forgot the suitcase.” I couldn’t believe he 8 all the details(细节)! “After you came back from the hospital you were9 because when you got home, the suitcase had been opened and everything had been thrown all over the place, and you 10 me.”“And you didn’t do it?” I asked.“No, I didn’t . I was just searching for my gift.”My heart sank（下沉）. I felt 11 . I hugged Keith and asked him to 12 me. His h onesty made me think of our other son, Kevin. Maybe I’d hurt his feel ings, too. I went to ask him the same question. Kevin’s answer was as immediate as his 13 , “Last Christmas you promised us a special toy, but you forgot about it.”Though Christmas had passed, I took my two sons to the store that day and bought them what I had promised. The 14 thing wasn’t the toy. The problem was that I’d made a promise too 15 and didn’t keep it as their father.1．A．showed B．expressed C．hurtD．attended2．A．candy B．book C．picture D．toy3．A．fact B．message C．idea D．challenge4．A．complained B．continued C．apologizedD．explained5．A．suggestion B．blame C．memoryD．answer6．A．school B．church C．hospital D．garden7．A．set off B．settled down C．went onD．got up8．A．knew B. imagined C．remembered D. discovered9．A．happy B．angry C．worried D．satisfied10．A．educated B．praised C．helpedD．punished11．A．terrible B．hopeless C．inspiredD．encouraged12．A．support B．criticize C．suspectD．forgive13．A．mother B．brother C．sisterD．father14．A．strange B．interesting C．important D．difficult15．A．lightly B．rudely C．equallyD．truly二、阅读第一节阅读理解（2×15=30分）AHave you ever considered the question: why different animals or pests (昆虫) have their special colors? The answer is that their colors in them seem to be used mainly to protect themselves.Some birds like eating locusts (蝗虫), but birds cannot easily catch them. Why? It is because locusts change their colors together with the change of the colors of crops(庄稼). When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown color as crops have. Someother pests with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.If you study the animal life, you’ll find the main use of coloring is to protect the animals themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters . This is because they have the colors much like the trees’.Have you ever noticed an even stranger act? A kind of fish in the sea can send out a kind of very black liquid when it faces danger. While the liquid spreads over, its enemies cannot find it. And it immediately swims away. So it has lived up to now though it is not strong at all.16. From the passage we can learn that locusts________.A. are small animalsB. are dangerous to their enemiesC. change their colors to protect themselvesD. are easily found by birds17. How can pests with different colors from plants keep themselves out of danger?A. They hide themselves by the day and appear at nightB. They have the colors much like their enemies’.C. They run away quickly. .D. They have to move quietly.18. Bears and lions can keep safe because _________.A. they have the colors much like the treesB. they move quietlyC. they like brown and gray colorsD. they live in forests19. Why can the kind of fish live up to now?A. Because it is very strong.B. Because the liquid it sends out can help it escape from its enemies.C. Because the liquid it sends out can kill its enemies.D. Because it swims faster than any other fish.20. Which is the best title for this passage?A. The Change of Colors for Animals and PestsB. Colors of Different Animals and PestsC. Some Animals and PestsD. The Main Use of Colors for Animals and PestsBIn February, the United States honors two great American presidents, Abraham Lincoln on February 12th, and George Washington on February 22nd.These two days are made into one legal holiday on the third Monday in February, called Presidents’ Day.Both presidents have been honored in different ways. George Washington is the only president to have a state named after him. The nation’ s capital, Washington D.C., also has his name. There are cities, towns, streets, schools, bridges, and parks named after both president Lincoln and president Washington. Both have famous memorials (纪念物，纪念馆) in Washington D.C. Their portraits (肖像) also appear on postage stamps, bills and coins. Washington’ s house in Mount Vernon and Lincoln’ s home in Spring Field, Illinois, have been made into museums.Cherry pie is a traditional food for Washington’ s Birthday because of a popular story about him. It is said that when he was a little boy, one day Washington cut down his father’ s favorite cherry tree. When asked by his father, he admitted his wrong doing and said, “I can not tell a lie.”21.

Because cherry pie is very good to eat.CSurveys of American teenagers find that about half of them do not get enough sleep on school nights．They get an average of 60 to 90 minutes less than experts say they need．One reason for this lack of sleep is biology．Experts say teens are biologically programmed to go to sleep later and wake up later than other age groups．Yet many schools start classes as early as seven in the morning．As a result, many students go to class feeling like sixteen-year-old Danny．He plays two sports, lacrosse and football．He is an active teen -- except in the morning．DANNY: "Getting up in the morning is pretty terrible．I'm just very out of it and tired．And then going to school I'm out of it, and through first and second period I can barely stay awake．"Michael Breus is a clinical psychologist (临床心理医生)with a specialty in sleep problems．Teens, he says, now commonly sleep for only 6．5 hours to 7 hours．He says sleepy teens can experience a form of depression（压抑）that could have big effects on their general well-being．It can affect not just their ability in the classroom but also on the sports field and on the road．So what can schools do about sleepy students? The psychologist says one thing they can do is start classes later in the morning．Eric Peterson is the head of St．George's School in the northeastern state of Rhode Island．He wanted to see if a thirty-minute delay would make a difference．It did．He says visits to the health center by tired students decreased by half．Late arrivals to first period fell by a third．And students reported that they were less sleepy during the day．Eric Peterson knows that changing start times is easier at a small, private boarding school like his．But he is hopeful that other schools will find a way．Patricia Moss, an assistant dean at St．George's School, says students were not the only ones reporting better results．PATRICIA MOSS: "I can say that generally all the teachers noticed immediately that kids were happier to be there at eight-thirty than they were at eight．"26．According to experts like Michael Breus, how many hours of sleep shouldteens get every day?A．6.5 hours to 7 hours．B．at least 7.5 hoursC．More than 9 hours．D．Less than 7 hours．27．According to some experts, why do teens wake up later than adults?A．Because they are lazier．B．Because they need more sleep．C．Because they are biologically programmed to sleep late and wake up late．D．Because they play sports．28．The article mentions the story of sixteen-year-old Danny to _____________．A．show how he hates getting up in the morning．B．show how teens can be affected by a lack of sleep．C．show how he turns from an active boy to a tired school child．D．show how teens hate school．29．What does Eric Peterson do about the problem of sleepy students?A．He visits the health center．B．He punishes late students．C．He punishes sleepy students．D．He starts his school time 30 minutes later．30．Which of the followings is not true according to the article?A．Later school time leads to fewer late arrivals．B．Eric Peterson’s experiment has answered his question．C．The writer of this article seems to support later school time．D．Teachers of St．George’s School don’t seem to support later school time．第二节信息匹配(2分×5=10分）请阅读下列应用文及相关信息, 并按照要求匹配信息，并在答题卡上将对应题号的相应选项字母涂黑。

Keep an eye out as you pass through forests, woodlands and open hills.The Isle of StaffaThe Isle of Staffa is famous for its dramatic rock formations, and for the cave known as “Fingal’s Cave”, Staffa provided inspiration to Felix Mendelssohn, the German musician. He visited in 1829 and, afterwards, composed his Hebrides Overture. The island is also famous for its adorable seabirds—puffins, which are known for their vibrant beaks (鸟喙) and big personalities.The Cairngorms National ParkThe Cairngorms National Park is in northeast Scotland. With an area of 1,748 square miles, the park covers the Cairngorms range of mountains and surrounding hills, and is the largest national park in the UK as the second national park in Scotland. Over 25% of the UK’s endangered species make their home in the park’s ancient pine forests, among which you can find the red squirrel—the UK’s only native squirrel (松鼠) species.21．Which of the following is connected with the creation of a piece of music?A．The Loch Lomond.B．The Trossachs National Park.C．The Isle of Staffa.D．The Caimgorms National Park. 22．What do we know about the Caingorms National Park?A．It supports a wide variety of rare animals.B．It lies off the coast of northeast Scotland.C．It is the only place to find the red squirrel.D．It is the second largest national park in Scotland.23．What is the purpose of the text?A．To give advice on how to spend holidays in Scotland.B．To introduce some places to see wildlife in Scotland.C．To raise awareness of endangered wildlife in Scotland.D．To compare some breathtaking destinations in Scotland.Dream in HeartOn the first day of school our professor introduced a new classmate—a wrinkled little old lady—to us. Her name was Rose, and she was eighty-seven years old.After class Rose and I walked to the Student Union Building and shared a chocolatemilk-shake. She told me she always dreamed of having a college education and now she was getting one. We became instant friends. Every day for the following months, we would leave class together and talk nonstop. I was always attracted, listening to this “ time machine” as she shared her wisdom and experience with me.Rose became famous and easily made friends wherever she went. She tended to be highly motivated,responsible, and deeply involved in class participation. In spare time she had someone hang out or go to bars with. She even participated in some form of athletic activity. She said that extra-curricular activities can form a vital part of her experience, creating unique chances for friendship and learning.At the end of the term we invited Rose to speak at our football meal. A little embarrassed, she leaned into the microphone and simply said, “ I’ m sorry I’ m so nervous.” As we laughed, she cleared her throat and began, “ We do not stop playing because we are old; we grow old because we stop playing. There is a huge difference between growing older and growing up. If you’ re nineteen years old and lie in bed for one full year, you will turn twenty. If I’ m eighty-seven years old and stay in bed for a year, I will turn eighty-eight. Anybody can grow older. It’ s non-optional but that doesn’ t take any talent or ability. The idea is to grow up by always finding the chance in change. In this way the elderly don’ t have regrets for what they did, but rather for things they did not do.” Rose concluded her speech by courageously singing “ The Rose” . She challenged us to study the words of the song and lived them out in daily lives.At the year’ s end Rose finished the college degree she had begun all those years ago. One week after graduation Rose died peacefully in her sleep. Over two thousand college students attended her funeral in honor of the wonderful woman who taught by example that it’ s never too late to be all you can possibly be.24．Why does the author compare Rose to “ time machine” in Paragraph 2?A．To stress her old age and knowledge of life.B．To describe the close friendship between them.C．To show that she always enjoyed her active life.D．To explain why she took on a challenge in college.25．Rose was invited to speak at the football meal most probably because ______.A．she was a great football fanB．she was the smartest studentC．she tried hard to achieve her dreamD．she became more educated than the others26．We can learn that Rose agreed with the idea that ______.A．growing older means growing upB．it takes talent and ability to grow upC．receiving high education helps to be courageousD．one grows older at the same time when he grows up27．The passage is intended to ______.A．provide an example for the elderly B．discuss how to grow up quicklyC．tell the importance of attending college D．inspire the readers to live up to livesLondon — Life for Cathy Hagner and her three children is set to permanent fast-forward. Their full school day and her job as a lawyer’s assistant are busy enough, but Hagner also has to take the two boys to soccer or hockey or basketball while dropping off her daughter at piano lessons or Girl Scout Club. Often the exhausted family doesn’t get home until 7 pm. There is just time for a quick supper before homework.In today’s world, middle-class American and British parents treat their children as if they were competitors racing for some finishing line. Parents take their children from activity to activity in order to make their future bright. It seems that raising a genius has become a more important goal than raising a happy and well-balanced child.“Doctors across the country are reporting a growing number of children suffering from stomachaches and headaches due to exhaustion and stress,” says child expert William Daherty of the University of Minnesota. Teachers are dealing with exhausted kids in the classroom. It’s a very serious problem.Many children attend after-school clubs by necessity. But competitive pressures also create an explosion of activities. They include sports, language, music and math classes for children as young as four.“There is a new parenting trend under way which says that you have to tap all your child’s potential at a young age; otherwise you will let him down,” says Terry Apter, a Cambridge-based child and adolescent psychiatrist(青少年精神病学家).“It isn’t entirely new: there have always been pushy parents. But what was previously seen as strange behavior is now well accepted.”28．From the first paragraph of this passage we can find that________.A．Hagner wastes much time helping her children’s lessonsB．Hagner doesn’t spend much time on her full-time jobC．Hagner is interested in sports and musicD．Hagner busies herself by following a trend29．American and British parents, as the writer described in this passage, ________.A．treat their children as sports players B．pay no attention to their children’slessonsC．bring up their children in a simple way D．give their children little time to develop freely30．The writer’s opinion about after-school clubs is that ________.A．activities in the country are too competitiveB．children should attend four clubs at a timeC．some activities result from competitive pressuresD．clubs should have more subjects for school children31．It can be inferred from the text that the writer’s attitude is________.A．parents used to take their children to every clubB．parents used to be wise about how to raise childrenC．parents have all benefited from children’s clubsD．parents have come to know the standard of educationWhile many of us may have been away somewhere nice last summer, few would say that we’ve “summered.” “Summer” is clearly a noun, more precisely, a verbed noun.Way back in our childhood, we all learned the difference between a noun and a verb. With such a tidy definition, it was easy to spot the difference. Not so in adulthood, where we are expected to “foot” bills, “chair” committees, and “dialogue” with political opponents. Chances are you didn’t feel uncomfortable about the sight of those verbed nouns.“The verbing of nouns is as old as the English language,” says Patricia O’Conner, a former editor at The New York Times Book Review. Experts estimate that 20 percent of all English verbs were originally nouns. And the phenomenon seems to be snowballing. Since 1900, about 40 percent of all new verbs have come from nouns.Even though conversion (转化) is quite universal, plenty of grammarians object to thepractice. William Strunk Jr. and E.B．White, in The Elements of Style — the Bible for the use of American English — have this to say: “Many nouns lately have been pressed into service as verbs. Not all are bad, but all are suspect.” The Chicago Manual of Style takes a similar standpoint, advising writers to use verbs with great care.“Sometimes people object to a new verb because they resist what is unfamiliar to them,” says O’Conner. That’s why we’re comfortable “hosting” a party, but we might feel upset by the thought of “medaling” in sports. So are there any rules for verbing? Benjamin Dreyer, copy chief at Random House, doesn’t offer a rule, but suggests that people think twice about “verbifying” a noun if it’s easily replaceable by an already existing popular verb. Make sure it’s descriptive but not silly-sounding, he says.In the end, however, style is subjective. Easy conversion of nouns to verbs has been part of English grammar for centuries; it is one of the processes that make English “English.” Not every coinage (新创的词语) passes into general use, but as for trying to end verbing altogether, forget it.32．What can we learn about the verbing of nouns?A．It hasn’t recently been opposed by many grammarians.B．It is more commonly accepted by children than adults.C．It hasn’t been a rare phenomenon in the past century.D．It is easily replaced by existing verbs in practice33．What is most leading experts’ attitude towards the practice of the verbing of nouns?A．Cautious.B．Satisfied.C．Disappointed.D．Unconcerned.34．What does the author think of ending the verbing of nouns?A．Predictable.B．Practicable.C．Approaching.D．Impossible.35．What is the best title for the text?A．Are 40 Percent of all new verbs from nouns？B．Are Summering and Medaling Annoying?C．Are You Comfortable about a New Verb?D．Are There Any Rules for Verbing?三、七选五根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
