    A few years ago, I got a phone call from a company representative on my way home. "Thank you so much for taking the time to apply for the position. Your application has not been successful. We wish you every success in securing a suitable position in the future." I felt very upset. But the conversation wasn't over. "Would you like to hear feedback from us?" the voice said.

    The representative went on to tell me I hadn't clearly demonstrated my motivation for applying for the position and why I wanted to work for the company. The feedback was tough to hear. But I quickly realized they were right. After completing my Ph. D. in Germany, my top priority had been to find a position in Poland, where I grew up. As a result, I wasn't very selective about what I applied for. I pursued any job opportunity that broadly fit my skills and interests. The job at the consulting company was something I was technically capable of doing, but I didn't feel passionate about it —— and that clearly showed in the interview process.

    From then on, I decided to carefully evaluate each job opening and only pursue ones that truly resonated(引起共鸣) with what I was passionate about. In my applications, I also began stating more clearly and emphatically why I wanted that particular job. Soon the approach started to pay off, as I got an offer for a postdoc position in Poland that I was truly excited about.

    A few years later, I found myself on the other side of the interview table. As a freshly hired group leader, I was interviewing candidates for the first Ph. D. position in my lab. I was particularly looking forward to talking with one candidate. On paper, his application looked great —— nice CV, good recommendations, strong cover letter. But the interview went badly. He didn't seem to have done any reading in advance about the research I was doing, which made me wonder whether he was truly interested in working with me.

    注意:

    1.续写词数应为150左右;

    2. 请按如下格式在答题卡的相应位置作答。

    I called to tell him I couldn't offer him the position.

    It has become easy for students to find and copy published material. But copying another person's writing without giving them credit can get students and other scholars into big trouble. 

    American copyright law protects original works of authorship including books, movies, music, images and artworks.  The owner can sell a copyright or permit others to use it because it is property and property ownership is protected by law in the U. S.

    The idea is that copyright helps society. If people can gain from their own creations, which are called their intellectual property(知识产权), then more people will want to create original works. The law, however, permits the unlicensed use of copyrighted works under what is called fair use. Fair use can include criticism, comment, news reporting, education and research. In education, students can include small parts of copyrighted work in their writing and research. But they must provide credit to the original creators through a citation which gives details about the source.

    Just as it is easy to copy, it is also easy for professors to know if a student has plagiarized. First, there are computer programs and artificial intelligence, tools that compare students' papers to large databases of published writing.  Second, if English is not a student's first language, a professor might recognize a change in wording and writing style. This could bring more attention to the student's paper.

     Professors could simply warn a student not to do it again, lower their grade, or they might fail the student in that class. In more extreme cases, a student may be temporarily banned or expelled from school.

    A. This behavior is called plagiarism.

    B. However, there are some limitations.

    C. Plagiarism is punished in different ways.

    D. Students must follow university policies on academic behavior.

    E. They can identify whether students have copied published writing.

    F. For example, it can automatically create citations and combine them into a list.

    G. The protection extends to computer software and the design of buildings and structures.

    As a worrying number of youngsters take up vaping(电子烟), the Government has announced a crackdown on laws to stop kids from becoming addicted to the dangerous habit.

    Disposable(一次性的) vapes are now set to be banned in the UK as part of the Prime Minister's new legislation(立法) to"stop youth vaping in its tracks". Recent research shows that one in five teens has now tried vaping, despite it being illegal for under-18s, and half of those who vape between 18 and 24 do so despite having no history of smoking.

    Last year, figures showed the number of adults using e-cigarettes in the UK had risen to the highest rate on record at roughly 4.3 million Brits. According to the charity Action on Smoking and Health, almost 1,000 serious adverse reactions to vapes were logged, including five deaths linked to e-cigarettes in the last decade.

    And it's not just over-the-counter vapes at the center of the country's vaping crisis —— fake e-cigarettes with deadly chemicals have sparked concerns. An investigation by the Mirror in 2023revealed one man's fears for his life after he suffered a collapsed lung as a result of a fake,unlicensed pack of vapes purchased from a corner shop in County Durham.

    Alex Gittins, 31, thought he bagged himself a bargain but ended up in hospital just hours later. He said: "I noticed an awful chemical taste in the back of my throat, then five to 10minutes later I felt what was like a stitch. I'm lying in A&E thinking I was going to die."

    A regular vaper was told he had just a one percent chance of survival after being left in need of a double lung transplant. Jackson Allard, 22, underwent the life-saving operation on January 1, putting an end to a series of serious health issues.

    Medical expert Stephanie Hansen has voiced concerns about the unknown long-term effects of e-cigarettes. She said: "Vaping or e-cigarette use is relatively new, so we don't necessarily know a lot of the long-term effects of vaping and that's honestly one of the scariest things about it."

    (1)、What has the recent research found?
    A、20 percent of UK teenagers have once vaped. B、It's against the law for teens to buy vapes. C、Vaping is commoner than smoking in the UK. D、5 people died because of vaping last year.
    (2)、Why are two examples given in Paragraphs 5 and 6?
    A、To suggest it's easy to be addicted to vaping. B、To state vaping ruins people's health seriously. C、To indicate it's illegal to buy fake e-cigarettes. D、To show the number of people vaping is on the rise.
    (3)、Which of the following might Stephanie Hansen agree with?
    A、It remains to be seen in what way vaping affects people. B、It will be long before people know the bad effects of vaping. C、It matters to inform people of the potential danger of vaping. D、It is difficult to prohibit adults from buying e-cigarettes.
    (4)、What is the text mainly about?
    A、Research into the habits of smokers in Britain. B、Causes of teens' addiction to vaping in Britain. C、British health issues drawing public attention. D、British government prohibiting disposable vapes.

    Legend has it that centuries ago, manatees(海牛) used to be mistaken for mermaids, so a sight last week at one Florida state park would have put ancient sailors in shock.

    Blue Spring State Park is home to one of the largest winter gathering sites for manatees in Florida, and recently, the park reached a new record when the number of manatees spotted in one group was nearly 1,000.

    Manatees typically flock to the park during the winter months. According to a Facebook post from the non-profit Save the Manatee Club, January 21 was one of the coldest mornings of the Florida winter season so far. The temperature of the St. Johns River, which Blue Spring sits on, was recorded at 14.9℃.

    To survive the cold winter weather, manatees will seek out water that is typically warmer than 20℃. This is because despite their thick-looking bodies, the blubbery animal affectionately known as the sea cow only has "about an inch of fat and a very slow metabolism(新陈代谢),meaning they cannot easily stay warm," says the state park.

    Since their spring water remains at a constant 22.2℃, and is protected from human recreational activity, Blue Spring makes the perfect manatee shelter during the colder months. "What's more, many manatees rely on artificial warm water sources from power plants, and these might be going offline in the near future. So having some of these manatees come to these natural warm water sites and finding them is really encouraging," says Cora Berchem, a research associate and the director of multimedia at Save the Manatee Club.

    According to the Florida Fish and Wildlife Conservation Commission, there are anywhere between about 7,000 to 11,000 manatees in Florida, which represents a large increase over the past 25 years.

    (1)、What does the underlined phrase "flock to" in Paragraph 3 mean?
    A、Escape from. B、Drop into. C、Depart from. D、Flood into.
    (2)、What do we know about Blue Spring?
    A、It serves as a recreation center. B、The temperature remains at 22.2℃. C、It is a well-preserved state park. D、Power plants heat the shelter there.
    (3)、What might be discussed following the last paragraph?
    A、Importance of protecting manatees. B、Why manatees' population grows. C、Unique living habits of manatees. D、How manatees fight against cold.
    (4)、Which might be the best title for the text?
    A、A Club Taking Measures to Rescue Manatees B、A Record Number of Manatees Spotted in Florida C、Florida: the Largest Winter Shelter for Manatees D、Manatees: an Animal Resistant to Cold Weather

    Many footballers struggle when they leave the beautiful game for retirement in their mid-thirties, with stories that are sad or even terrible. However, in his new book Kicking On!, Tony Rickson reveals the footballers who have achieved success after retirement, whether it's by setting up charities, helping others cope, creating multi-million-pound businesses or going into media, politics or back into the football world.

    Tony Adams, a former footballer, set up a charitable foundation more than 20 years ago called Sporting Chance and said it's one of his greatest achievements. He's wrong. Despite all the cups he won while captaining Arsenal during a highly successful 22-year career at his only club, and all the times he played for England, it is his greatest achievement. Not just one of them.

    As Adams admits in his memorable book, Addicted, he suffered from alcoholism and drug abuse while still a professional footballer. Setting up Sporting Chance was his response, and ever since it's treated and supported sports professionals suffering from drink or drug problems. The charity's offer is: "We understand that it takes courage to ask for help, either during or following a career in sport, so when you're ready to reach out, we're ready for you."

    Since retiring from playing in 2002, Adams, who has a statue in his honor outside the Arsenal ground, has managed and coached in several countries alongside his charity work. He told The Sun: "What happened in my life with alcohol makes me feel so sad but also grateful that I found a way out of it. I've had highs and lows, in and out of football, given up playing and gone into coaching and management. I've not had a drink through any of it. My self-esteem (自尊) has come back and I am all right."

    The self-assessment as "all right" also applied to his 2022 appearance in TV's Strictly Come Dancing, when Adams showed an admirable ability to laugh at himself.

    (1)、What is Adams' greatest achievement according to Rickson?
    A、Setting up Sporting Chance. B、Captaining the team Arsenal. C、Playing for England all his life. D、Writing his bestseller Addicted.
    (2)、What problem did Adams have as a professional footballer?
    A、Losing his position on the team. B、Lack of courage to seek advice. C、Addiction to alcohol and drugs. D、Tense relations with teammates.
    (3)、What can we infer about Adams from Paragraph 4?
    A、Adams worked as a coach immediately he retired. B、Charity work made Adams recognized in his circle. C、Adams began his football career at the age of 22. D、Arsenal thinks highly of Adams' contribution to it.
    (4)、What is the text?
    A、A news report. B、A biography. C、An introduction to a book. D、An entry of a diary.

    As my parents worked a late shift, my three small sisters looked at me. "What's for dinner?" one of them said. The last time I made dinner was when I made pizza in high school. Now, I had three mouths to feed—ages two, six and nine—but I was short on ideas. Like a deer in headlights, I searched for a possible answer.

    "Where's the Twister (转盘游戏) game?"

    "Not Twister," Abby, my oldest sister, scolded, "Dinner. "

    I walked to the closet, pulled out the game. and tested the spinner (转盘). Then I slid a couple of sheets of paper between the plastic arrow and the cardboard base and divided it into four quadrant (象限). I looked at my sisters. 

    "Who wants chocolate?" Alice, my youngest sister, screamed happily. Abby crossed her arms. "Mum wouldn't let that happen. "

    "Mum's not here. "I wrote in the upper right quadrant: chocolate. Andy, my middle sister, asked, "What are you doing?"

    "You'll see in a second." I pointed at the second area. "How about noodles?" Alice started dancing around in a circle.

    "When we get four options written on the spinner, we'll spin to see what we do for dinner tonight."

    My youngest sister said, "Dress up like superheroes. "

    "Absolutely!" I wrote superheroes, with no idea how that would turn into a dinner idea, hoping the dial would land somewhere else. They debated the final section for a few seconds and then collectively decided on pizza. If they had suggested "Run around at the mall", I would have written it down. I set the spinner in the middle of the table. We gathered around the spinner, and I held up my hands. "We are going to spin it once, and whatever we land on、that's what we'll do tonight. "

    Abby shook her head. "I don't think this is a good idea." "It's okay, honey. Mum will understand. "

    Alice yelled, "I want to spin it. "Alice's try sent the little, plastic arrow flying around and around until it landed on... pizza. Everyone shouted, "Pizza", including me. I still had no idea what we were going to do. Abby looked at me. "But what are we going to do?"

    Are you familiar with pop star Jay Chou'sBlue &White Porcelain? Its original lines, just the composer Fang Wenshan described, were inspired by Ru porcelain (汝瓷).

    Ranked best among famous kinds during the Song Dynasty (960-1279), Ru porcelain is known for its unique pale blue glaze (釉). Oceans  Ru porcelain flooded onto the market around the year of 1100, but the  (exist) of Ru ware now is actually rare. Thanks to the efforts of Ru porcelain inheritors, people can now appreciate it  (close) at hand than before.

    Born in Ruzhou, Henan province, Li Chao has spent a decade  (better) crafting skills. Ru porcelain goes through 72 steps, the (one) of which is knead (揉) mud. Any small errors could lead to disaster, said the 41-year-old inheritor. He then stressed that a Ru porcelain inheritor must be patient enough. Every item of artwork  (full) deserves our admiration.

    Techniques of making Ru porcelain will (lose) with senior inheritors gradually passing away. So, Li spares no effort in doing is introducing it to wider masses. (achieve) this goal, he creatively uses Ru porcelain in making daily ware popular among young people. Now he's aiming to expand the market by introducing it to the whole world.

    Inconvenient Truths

    If doctors lie, it is surely inexcusable. One of the basic1 the public have of doctors is honesty. But what would you think if I told you that research has shown that 70 per cent of doctors  2 to lying to their patients? If I am honest, I have told lies to my patients. 

    Mrs Walton was in her eighties and3 to see her husband. She would try to get up to find him, despite being at risk of falling. "He's on his way, don't worry," the nurses would say this to calm her down. I said the same thing to her. But it was a lie. He died two years ago. The truth, if I can use that word, is that it is a4 to lie sometimes.

    Mrs Walton is one of the dementia(痴呆) sufferers, who lose their short-term memory and the memory of5 events, but hold memories from the distant past. Sufferers are trapped forever in a confusing past that many realize bears little  6 to the present, but are at a loss to explain. Those with dementia often feel upset, scared and confused that they are in a strange place, 7 by strange people, even when they are in their own homes with their family, because they have gone back to decades ago.

    They look at their adult children  8 and wonder who they could be because they think their children are still little kids. I have had countless families break down in tears, not knowing how to react as their loved one moves further away from them back into their distant past and they are  9 in the present. And how, as the doctor or nurse caring for these patients, does one manage the anger and outbursts of distress that comes with having no  10 of your life for the past ten or 20 years? The lies that doctors, nurses and families tell these patients are not big, elaborate lies — they are  11 comforts intended to calm and allow the subject to be swiftly changed.

    12 with them about this false reality is not heartless or unprofessional — it is actually kind. That's not to say that lying to patients with dementia13 is right or defensible. But what kind-hearted person would put another human being through the unimaginable pain of learning,14 again and again, that they have lost their beloved ones. It would be an unthinkable cruelness.

    Sometimes honesty is 15 not the best policy.

  • 20、阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。

    Some of the oldest living things on our remarkable planet are trees. The record holders are bristlecone pines (狐尾松) of the western United States, quite a few of which are known to be more than 3,000 years old. One individual, discovered in 2012, is estimated to be more than 5,060 years old, making it the oldest known non-clonal tree in the world! : individuals across a number of other tree species have also been around for thousands of years.

    So, how do trees survive for thousands of years? . Undoubtedly, part of the answer lies in luck. Ancient trees have obviously not submitted to deadly diseases, pests, fires, droughts, windstorms, landslides, or the human axe in the centuries and centuries that they have quietly endured.

    The other part of the answer has to do with how trees age. In fact, there is quite a debate about whether ancient trees can be considered "immortal (永生的)". That is, will such trees ever die if they are not killed by an outside force? We may never know the answer to that, but, at the very least, . While cell death is an important factor in the aging of humans and other animals, one study found little evidence of cell death in the ginkgo tree vascular cambium (银杏树维管形成层). In addition, a study of bristlecone pine pollen (花粉) found no significant increase in mutation (变异) rates with age, which is another factor associated with animal aging. .

    Older trees benefit greatly from having bodies made mostly of dead woody tissue. In fact, an old tree might be as much as 95 percent dead tissue! Given that it isn't alive, wood does not require metabolic (新陈代谢的) activity to maintain it, .

    A.so an old tree doesn't really need to do much to keep living

    B.This is a question that has something to do with the good luck of trees

    C.However, bristlecones are certainly not alone in terms of the oldest creatures

    D.This is a fascinating question for biologists that does not yet have a settled answer

    E.What's more, some ancient trees have superior chemical defenses against pests and diseases

    F.which means that trees can survive everywhere without being limited by external and internal conditions

    G.we know that ancient trees age in ways that are dramatically different from the ways that most animals and even other plants age
