【新东方在线版】【分科目整理】一、作文&参考范文作文题目：翻译软件的使用Directions: For this part, you are allowed 30 minutes to write an essay on the use of translation apps. You can start your essay with the sentence "The use of translation apps is becomging increasingly popular. " You should write at least 120 words but no more than 180 words.【参考范文一：新东方版】The use of translation apps is becoming increasingly popular. Why? Admittedly, in the contemporay society, an increasing number of people, with the help of translation apps, find it convenient to read foreign literature or essays.On the one hand, these apps can bring users greater efficiency and help them save more time or energy, particularly for those who have no knowledge of a foreign language. For instance, a host of people may have a variety of difficulties or troubles in learning English, but with the assistance of these apps, it will not be difficult for them to read and understand English materials. On the other hand, it is these apps that cuase some learners to lose motivation for studying. With Apps in hand, they are not willing to do their utmost to memorize new words, pratice speaking or writing skills every day. Fianlly, they will fail to get a good command of any foreign language.I, as a college student, deem that it is of great necessity for youngsters to use translations apps in a rational way. We should bear in mind that any translation app is merely a tool. Provided that one intends to master a foreign language, it is advisabel to practice each day instead of relying on translation apps.译文翻译APP的使用变得越来越普遍流行。

Then, a good luck charm that he kept under his bed changed his life. The unidentified man fished out a giant pearl from the ocean when his anchor got stuck on the rock while sailing off a coastal island in the Philippines 10 years ago. (6) When he was forced to sell it, (7) the shocked tourist agent at Puerto Francesca told him that the £77 giant pearl that he had kept hidden in his run-down wooden house was the biggest pile in the world, which was valued at £76 million. The pearl of Allah, which is currently on display in a New York Museum, only weighs 14 pounds. That is 5 times smaller than the pearl that the fisherman just handed in. The monstrous pearl, measured at 1 foot wide and 2.2 feet long, is going to be verified by local experts and international authorities before hopefully going on display to attract more tourists in the little town.Question 5.

He's actually in the construction business, which was really helpful.W: Well, honestly, I'm impressed. I knew I could probably repaint the walls in my house over a weekend or something, but not a full renovation. Where did you get your ideas? I wouldn't know where to start.M: (13) Well, for a while now, I've been regularly buying home design magazines every now and then, and say the picture I liked. Believe it or not, I had a full notebook of magazine pages. Since my overall style was quite minimal, I thought and hoped the whole renovation wouldn't be too difficult. And sure enough, with Greg's help,it was very achievable.W: Was it very expensive? I imagine a project like this could be.M: (14) Actually, it was surprisingly affordable. I managed to sell a lot of my old furniture, and put that extra money towards the new material. Greg was also able to get some discount of materials from a recent project he was working on as well. W: Great. If you don't mind, I'd like to pick your brain a bit more.

Children were responsible for the vast majority of cases. 95% of objects removed from noses, and 85% from ears. Every year, an average of 1,218 nose，and 2,479 ear removals took place between 2010 and 2016. (17) According to England's hospital episodes statistics, children aged 1 to 4 were the most likely to need help from doctors for a foreign object in their nose. 5 to 9 -year-olds come to the hospital with something in their ears the most.Jewelry items accounted for up to 40% of cases in both the ears and noses of children. Paper and plastic toys for the items removed next most from noses. Cotton buds, and pencils were also found in years.(18) According to the study, the occurrence of foreign objects in children is generally attributed to curiosity. Children have an impulse to explore their noses and ears. This results in the accidental entry of foreign objects. Any ear, nose and throat surgeon has many weird stories about wonderful objects found in the noses and ears of children and adults. Batteries can pose a particular danger. In all cases, prevention is better than cure. This is why many toys contain warnings about small parts. Recognizing problems early and seeking medical attention is important.Question16 What does England spend an annual￡3 million on?C. Removing objects from patients’ noses and ears.Question17 What do we learn from England's hospital episodes statistics?B. Five-to nine-year-olds are the most likely to put things in their ears. Question18 What is generally believed to account for children putting things in their ears or noses?D. They are curious about these body parts.Passage 2(21) Good morning. Today, I would like to talk to you about my charity Re-bicycle.But before that, let me introduce someone. This is Layla Rahimi. She was so scared when she first moved to new Zealand. Does she struggled to leave the house? I would spend days working up the courage to walk to the supermarket for basic supplies.(19) After a few months of being quite down and unhappy, she was invited to joina local bike club. At this time, Re-bicycle got involved and gave Layla a second-hand bicycle. Within weeks, her depression had begun to ease as she cycled. The bicycle totally changed her life, giving her hope and a true feeling of freedom. (20) To date, Re-bicycle has donated more than 200 bikes to those in need and is now expanding bike-riding lessons as a demand source. With a bike, new comers here can travel farther but for almost no cost. The 3 hours a day they used to spend walking to and from English language lessons has been reduced to just 1hour.(21) Our bike riding lessons are so successful that we are urgently looking for more volunteers, learning to ride a bike is almost always more difficult for an adult. And this can take days and weeks rather than hours. So if any of you have some free time during the weekend, please come join us at Re-bicycle and make a difference in someone’s life.Question 19. What did Re-bicycle do to help Layla Rahimi?A. It gave her a used bicycle.Question 20. What is Re-bicycle doing to help those in need?A. Expanding bike-riding lessons.Question 21. What do we learn from the passage about Re-bicycle?D. It is a charity organization.Passage 3Thanks to the international space station, (22) we know quite a bit about the effects of low gravity on the human body, but NASA scientists want to learn more.To that end, they have been studying how other species deal with low gravity, specifically focusing on mice. The results are both interesting and humorous. The scientists first sent some mice and especially designed cage to the international space station.The cage allowed them to study the behavior of the mice remotely from earth, via video.As you’ll notice in the video, (23) the mice definitely seem uncomfortable at the beginning of the experiment.They move around clumsily, drifting within the small confines of the cage and do their best to figure out which way is up, but without success. However, it’s not long before the mice begin to catch on.They adapt remarkably well to their new environment, and even use the lack of gravity to their advantage as they push themselves around the cage. That’s when things really get wild. (24) The 11th day of the experiment shows the mice are not just dealing with the gravity change, but actually seem to be enjoying it. Several of the mice are observed running around the cage walls. The scientists wanted to see whether the mice would continue doing the same kinds of activities they were observed doing on earth.(25) The study showed that the mice kept much of the routines intact, including cleaning themselves and eating when hungry.Question 22 : What do NASA scientists want to learn about?A. How animals deal with lack of gravity.Question 23: What does the passage say about the mice at the beginning of the experiment?C. They were not used to the low-gravity environment.Question 24: What was observed about the mice on the 11th day of the experiment?B. They already felt at home in the new environment.Question 25: What did the scientists find about the mice from the experiment?

This finding surprised researchers who admitted they didn't expect that eating white meat would lead to higher blood cholesterol levels. In the study, researchers looked at 113 healthy people. The participant in three different diets. These were a red meat diet which is primarily beef, a white meat diet which is mostly chicken and turkey, and a vegetarian protein diet. Each diet period was four weeks. Between the diet periods, participants had a break during which they ate their regular foods. In addition, participants had blood tests at the start and finish of each new diet. The results showed that white and red meat diets had the same effects on blood cholesterol levels. Further, both diets increased blood cholesterol levels compared to the diet built on vegetarian protein sources. The team acknowledged that it is possible that white meat is better for our health than red meat,despite their findings. This is because other effects of red meat consumption could contribute to heart disease, independent of cholesterol. Their main recommendations are that people eat less of both kinds of meat. And more vegetarian protein.Q1: What do we learn from the news report about the study?Q2: What did the researchers acknowledge?NEWS 2At around half past nine this morning, a trailer attached to a lorry turned over at the crossing of high street in Milton. Hundreds of frozen turkeys were spilled all over the road. It is reported that nobody was hurt in the incident, but police said it may affect traffic and Christmas dinners. With just one week to go before Christmas, there are worries that local supermarket supplies of this holiday favorite may be affected. A police spokeswoman said that officers were currently in attendance at the scene. She stated that the driver of the lorry had been arrested on suspicion of dangerous driving. The crossing on high street is a well-known accident black spot. This year alone, there have been seven traffic accidents at this location.Thankfully, none of these accidents have resulted in serious injury.Q3: What does the news report say about the accident at the crossing of high street and Milton ?Q4: What do we learn about the crossing on high street?NEWS 3India launched its helicopter taxi service on Monday promising to ferry customers, the 40 miles between Bangalore's electronic city tech hub and the international airport terminal in 15 minutes.Customers can book their helicopter ride through a mobile app.The service, which claims to be the first of its kind in India offers only one room. But Bangalore airport will add more once it gets approval.Helicopter taxi is not an affordable option for many travelers. A car ride for the same journey costs less than half as much. But Bangalore airport says it is a competitive alternative to a car ride for tech executives in a hurry.A large number of high class travelers, including CEOs have to spend more than three hours by road to get there.And that is a loss of time.A Bangalore airport spokesperson said this is not a low cost option, but it is an option. She added.The helicopters ferried around 8 customers to the airport on their first day. The company that owns and operates the service is called Loinbo Thumby aviation. It previously specialized in private charter flights for government officials.Q5: What is Bangalore airport trying to do about the helicopter taxi service?Q6: What do we learn from the news about the helicopter taxi ride?Q7: Who are the targeted customers of the helicopter taxi service?COVERSATION 1W:Hi, I wish to buy some cheese for a barbecue this weekend.M:What kind would you like?W:Sorry, I don't know much about cheese. What type do you think would besuitable for a barbecue?M: That's easy. For a barbecue,you could have any cheese you want. I imagine there will be different foods and people will just help themselves and eat at their own pace, right?W:Yes, exactly. It will be very casual. We will just be a small group of friends gathering together at Washington park. There will be around 20 of us, including children.M:Great，so you could have different types of cheese. How much would you liketo spend?W:Not very much. Let's say $30.M:I would suggest having at least one soft cheese and one hard cheese，that will offer you a good variety to suit different people's tastes.W:That sounds good. What's the difference between a soft cheese and a hard cheese?M:Well, but generally speaking, soft cheeses are creamy and go well with sweet things like honey and jam. I would suggest something like this Spanish goat cheese,it's only $15,a very good price. You can spread it on bread with a knife and then add a tiny bit of honey on top. It's delicious. Children love it.W: Okay, great. What about a hard cheese?M:Yes,for hard cheese, I would recommend this Italian one here. It has a very strong smell and a dry flavor. You can cut it into thin slices and eat it on itsown.It's $16.W:Okay, I'll take both. Thank you for your help.Q8: What does the woman plan to do for the weekend?Q9: What does the man suggest the woman do?Q10: What does the man say about Spanish goat cheese question ?Q11: What is the woman going to do at the end of the conversation?COVERSATION 2M: Our school is replacing printed textbooks with E textbooks next semester.I can't wait.W: Really? What about the cost? Not only buying all those tablets, but the software, and electronic infrastructure that goes with it, not to mention retraining all the teachers and administration staff.M: Sure. The initial expenditure will be high But much lower afterwards. Besides that tablet prices continue to drop and are becoming increasingly affordable. Anyway, tablets help students learn up to 80% faster.W: Not necessarily tablets have too many distractions. Students may pay attention to apps, games, and websites instead of their teachers. In fact, Research suggests that people who read printed text comprehend more, remember moreand learn 30% more than those who read digital text.M: Yes, but tablets contain many technological features that are not found inprinted textbooks. Think about it. Students are able to highlight and edit text, write notes and search for information much more quickly than they can with printed textbooks. And what about all those trees that are cut down to make printed books?W: Actually manufacturing tablets is environmentally destructive and dangerousto human health. The health impacts from making one electronic reader are 70 times greater than those from making a single printed book. A lot of minerals are extracted from the earth to make electronic reader.It does far more damage to the environment?M: Yes, but the software for electronic readers can be updated instantly without the need for buying a whole lot of new books.that's better for the environment, W: But the core curriculum doesn't change that much printed textbooks that are not brand new, still contain the basic relevant information of core subjects. M: Well, I'm looking forward to the change.I'll stick with my printed books.Q12: What does the woman say about using E textbooks?Q13: According to the man. How can the use of tablets benefit students?Q14: What does the woman say about students using tablets?Q15: What does the woman say about making electronic readers?PASSAGE 1In social psychology, the term “person perception” refers to the mental processes that we use to form impressions of other people.It includes not just how we form these impressions,but the conclusions we make about other people based our impressions.Consider how often you make this kind of judgment every day.When you meet with a new coworker, you immediately begin to develop an initial impression of this person. When you visit the grocery store, you might draw conclusions about the cashier who checks you out.Obviously, person perception is a very subjective process that can be affected by a number of variables, including the characteristics of the person you are observing, the context of your situation, your own personal traits and your past experiences. One of the techniques we use in person perception is social categorization. In this process, we mentally categorize people into different groups based on common characteristics.Problems with this technique include the fact that it can lead to errors and prejudice.Imagine that you are getting on a bus. There are only two seats available. One is next to a small elderly woman. The other is next to a muscular, fierce looking man. You sit next to the elderly woman who unfortunately turns out to be quite skilled at picking pockets.Because of social categorization, you immediately judge the woman as harmless, andthe man as threatening,leading to the loss of your wallet.Q16: What does the passage say we tend to do every day?Q17: What do we learn about person perception from this passage?Q18: What is the problem with using social categorization in person perception?PASSAGE 2Young people today are as socially competent as those from the previous generation. At least this is what a new study suggests.For the study,researchers compared teacher and parent evaluations of American children who started kindergarten in 1998, with those who began school in 2010. The former group entered kindergarten when mobile phones were luxuries . The latter groupstarted school when mobile devices were widespread.Results showed both groups of children were rated similarly on important social skills. These includedthe ability to form and maintain friendships and get along with people who were different. They were also rated similarly on self-control such as the ability to regulate their temper. In virtually,every comparison made ratings of social skills either remaining constant or improved for the children born later. There was one exception. Social skills were slightly lower for children who accessed online games and social networking sites many times a day. Adults are worried when technological change starts to undermine traditional relationships, particularly the parent-child relationship. The introduction of telephones,automobiles andradios all led to moral panic among adults of the time because the technology allowed children to enjoy more freedom Fears over screen based technology represent the most recent panic in response to technological change. But overall,the study found little evidence at time spent on screens was hurting social skills for most children.Q19: What does the new study suggest about young people today and those fromthe previous generation ?Q20: What did the study find about children who accessed social networking sites many times a day?Q21: What does adults worry about technological change?PASSAGE 3You can find incredible videos, articles, and those stories about the success of others. The problem is that consuming the success and ideas of others is passive inspiration. Every time you read an article or listen to an interview, you are practicing passive inspiration. You might learn something, but you don't actually have to do anything. Hearing about other people's success isn't the same as creating your own success.Instead, it is through the process of active inspiration-the act of creating things, applying new ideas to our goals and making mistakes-that we discover who we are and what is important to us. Furthermore, active inspiration is what results in longterm passion and enthusiasm. Watching someone else's success might leave you feeling excited for a few minutes.However, taking action and applying a new idea to your life will inspire you more than anything someone else could say. Learning and listening can help you thinkabout things in a different way, but creating, producing, and experimenting is what drives you forward. Passive inspiration can give you ideas, but active inspiration will give you power.Too often we spend our lives consuming the world around us instead of creating it. And what matters is the power your actions have to inspire you. The best inspiration comes from the application of ideas, not the consumption of them.Q22:What does the speaker say about inspiration from consuming others' ideas and success stories?Q23 :What do we learn from the passage about active inspiration ?Q24:What does the passage say passive inspiration can do?Q25: Where does the best inspiration come from According to the passage?听力题 Section

While 92% of people believe others care most about fame and 26 , fewer thanl0% factor those qualities into their own success. This is according to the newly 27 study by Harvard Graduate School of Education professor Todd Smith. Smith says he was 28 by how past studies on success “assumed whatpeople will care about".In this study, his team "went the 29 direction" by spending years carrying out individual interviews and group surveys to seewhat peoplereallytalkaboutwhentheytalkaboutsuccess.As a scientist, Smith 30 studied individuality for a living, and even he was surprised to find younger respondents cared more about having a 31 inlife.Those between the ages of 18 and 34 prioritized it most, and that prioritizationdropped off as respondent’s ages went up. Perhaps this is because older people had fewer options when they were starting their careers , at a time when values focused more on stable incomes than 32 personal missions.Other trends included an emphasis on the importance of parenting. Being a parent 33 very high across the priorities of all studyparticipants. Ultimately,Smith hopes institutions will take note of these insights 34 .Higher education institutions tend to focus on preparing students for high-paying jobs.

Each statement contains information given in one of the paragraphs.Identify the paragraph from which the information is derived.You may choose a paragraph more than once. Each paragraph is marked with aletter.Answer the questions by marking the corresponding letter on Answer Sheet 2. How a rabbit study and an ex-student boost my hopes fora future of 'love and dignity'[A] At whatever grade level teachers find themselves,from kindergarten to the final class at medical or law school,few moments stir the emotions as deeply as when former students reappear years and often decades later with an update on where their journey has taken them and what resiliencies (韧性) have been the pavement on which they've traveled.[B] So it was when a recent letter came from Kelli Harding,a student 21 years ago inmy Peace Studies summer course in Washington.The weekly tuition-free class,ina roomy space that Ralph Nader and his Public Citizen nonprofit groupprovided,was discussion-based and required no useless homework or exams.Just come in and figure out how to increase peace and decrease violence.And do it today,tomorrow is too late.The course attracted mostly congressional interns (实习生)，with a few exceptions like Kelli who was in Washington as an AmeriCorps volunteer.[C] Her year-long service included comforting AIDs patients at a free health clinic and delivering meals to the homebound.It was a world apart from her undergraduate days at the University of Califoria-Berkeley majoring in political science.The Washington experience,which Kelli would later call "transformative,"was the fuel that carried her into medicine to earn a master'sdegree in public health from Columbia University and a medical degree from theUniversity of Rochester,and almost two decades of practice as an emergency- room psychiatrist (精神科医生) at New York-Presbyterian Hospital and a clinical professor of psychiatry at Columbia University Irving Medical Center.[D] Kelli's letter,a literate update on both her personal and professionallife,touched my hear, and especially so when saying that two decades later she still has the course text,"Solutions to Violence,"and that "it remains one of my favorite possessions."She lives in Lower Manhattan with her husband,Padraic,whom shemet on a flight to London,and their three boys.[E] If Kelli stands out,it's because she is also a gifted st month,Atria Bookspublished her book The Rabbit Effect:Live Longer.Happier,and Healthier with the Groundbreaking Science of Kindness.[F] With a blending of free-flowing confessional prose and scholarly research found in 461 notes, Kelli met my expectations that her ideas and ideals would be sound and singular."Despite our scientific progress,"she writes,"Americans are remarkably unhealthy.In 2016,the United States ranked forty-third in the world for life expectancy....It is also by far the world's most expensive place to get sick."[G] Enter the rabbits-not those running around in our woodlands but ones serving in two month-long medical experiments to test the effects of eating a high-fat dietand the connections between cholesterol and heart disease.With similar diets,the expectations were that all the rabbits would have similar cloggings of their arteries (动脉堵塞).Yet one group had 60%fewer of them.[H] The reason?Instead of receiving the standard care given to lab animals,the 60%group was watched over by a newcomer to the lab who,Kelli writes,"handledthe animals differently. When she fed her rabbits she talked to them and petted them.She didn't just pass out food, she gave them love....The studies indicate something is missing in the traditional biomedical model.It wasn't diet or genetics that made a difference in which rabbits got sick and which stayed healthy.It was kindness."[I] Amid the political noise about Obamacare,Medicare,Medicaid,health insurance and thieving pharmaceutical (医药 )companies,Kelli Harding stands apart fromthe crowd calling for quick fixes,the simpler the better.She has walked too many miles in the halls of hospitals visiting too many far-gone patients and seeing too many medical mistakes to go along with conventional thinking.[J] "The rabbit effect,"she explains,means that "when it comes to our health,we've been missing some crucial pieces: hidden factors behind what really makes us healthy. Factors like love,friendship,and dignity. The designs of our neighborhoods,s chools, and workplaces. There's a social dimension to health that we've completely overlooked in our efforts to find the best and most cutting-edge。

此正确答案为C选项。
【听力原文】News Report ThreeLions have disappeared from much of Africa, but for the past few years scientists have wondered if the big cats were hanging on in remote parts of Sudan and Ethiopia. 【5】 Continuous fighting in the region has made surveys difficult. 【6】But scientists released a report Monday documenting, with hard evidence, the discovery of “lost lions”. A team with Oxford University’s Wildlife Conservation Research Unit, supported by a charity organization, spent two nights in November camping in the National Park in northwest Ethiopia, on the Ethiopia-Sudan border.【7】The researchers set out six camera traps capturing images of lions, and identified lion tracks. The scientists concluded that lions are also likely to live in the neighbouring National Park across the border in Sudan. The International Union for Conservation of Nature had previously considered the area a “possible range” for the species, and local people had reported seeing lions in the area, but no one presented convincing evidence.【杀掉拦路虎】 1.

Sleep is necessary for good health. During this time, the body recovers from the activities of the previous day. The rest that you get while sleeping enables your body to prepare itself for the next day. There are four levels of sleep, each being a little deeper than the one before. As you sleep, your muscles relax little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourthlevel, your body shifts back and forth from one level of sleep to the other.Although your mind slows down, from time to time you will dream. Scientists who study sleep state that when dreaming occurs, your eyeballs begin to move more quickly (Although your eyelids are closed). This stage of sleep is called REM, which stands for rapid eye movement.If you have trouble falling asleep, some people recommend breathing very deeply. Other people believe that drinking warm milk will help make you drowsy. There is also an old suggestion the counting sheep will put you to sleep!1. A good title for this is ____.A. SleepC. DreamsB.

很明显答案C. essential符合条件，B选项有可信的意思，看到此选项可能下意识地会选这个答案，但翻译成“信任是可信的”，和主旨无关，此处还是讨论信任的重要性。
29题容易选一个名词比如records和”mistakes”并列，但是后面的选项并没有双引号，后面是一个动词reminding，可以推测前面需要填入副词来修饰reminding，根据语义“要求你做这做那”，可以推出是不断要求，而不是properly恰当地，排除完可以得出constantly.31题，此处判断应填名词，有同学可能会和pressure弄混淆，但此处并不能得出公司要施加压力。

And research shows that in recent years, its ice has melted faster than ever before.This month as temperatures in Northwestern Greenland approach, all time highs, researchers are encountering unusual,surprising levels of melting ice in the region.

Back in the late 1980s, being a deaf person in tech required a huge amount of effort and organization because there was no email or text message service. Everything had to be done face to face or by telephone. Communicating in meetings was very difficult. He needed a sign language interpreter for every meeting, but it was a huge effort to coordinate."These days, although challenges still remain, it's a good time to be a deaf person in tech, "says Miller Oaduoy. (17) "Big advances in speech recognition technology have enabled communication tools to turn live speech into text in real time on your smartphone or laptop, and sign language into text as well."New tech coupled with improvements in hearing aid, technology and medical advances means that Miller is able to focus far more on his work.He has benefited to a great extent from a tiny hearing device in his ear. It gives him a degree of hearing, and he can use a variety of communication methods depending on the situation. (18) He can employ lip reading and have meetings via video instead of on the phone. These things have made a huge difference. He no longer has to worry about whether or not he can understand.He can just concentrate on how interesting the meeting might be and what he needs to get out of it in order to progress.Q16.

According to one interior designer when people return home, (19) they want to see colors that cheer them up and give them a hug. Pure white walls simply don’t do that. They don't look after you. Another interior designer commented that certain combinations can key into something on a deeper level, transporting you to a different moment in time.That's the power of color.If you are thinking to dry color on some of your neutral walls, the advice is refreshingly simple. Choose a color you actually like. (20) Don't go for a color because it's in fashion, or you've seen it in a magazine. If you're wary of full color, test your tolerance with smaller spaces such as the inside of a cupboard or a bright window frame. if it gives you joy every time you open the cupboard, you can start to take it further.(21) One can also paint the wooden frameworks the same color as the walls. Helping the rooms look bigger. In the kitchen, painting the overhead cupboards and the walls in the same color can make it feel more spacious . While painting the kitchen counters, a bold color can make everything feel more open and lighter. Additionally, a painted ceiling is a magical thing without being too obvious and can affect how the space feels as well.Q19. What do people want upon returning home according to the passage?A) To find pure white walls shining.B) To enter a house well looked after.C) Big advances in sign language.D) To see cheerful colours all around.KEYS:D)To see cheerful colors all around.Q20.

It followed infants across the second6 months of life and found that when parents showed babies books that (24) had faces or objects with specific label, they learned more.This is in contrast to books that did not name images or books that had the same label under each image. Books that named different characters also promoted greaterlearning.So what does this mean for parents?Not all books are created equal, so parents need to choose the books they share with their children with great care.Q22.

The research examined three studies26more than 18,000 participants. Across all three, parenthood was27with more positive wellbeing outcomes for dads than for mums.So why are fathers happier than mothers? "Fathers may fare better than mothers in part du to how they spend time with their children,"said lead author Katherine Nelson-Coffey. In one study,the authors28that dads were more likely to take "playing"as an 29activity both when caring for their kids and spending time with their kids, *playing with their childre likely offers parents opportunities to experience positive feelings and 30_ closeness wit their children," they say Fathers also did better than men without kids, reporting greater happiness, life satisfaction, and fewer31symptoms They also reported greater connectedness and autonomy (自主 For mums32compared to women without children, the results weren't quite as positive Mums reported greater autonomy, but also "greater trouble" and fewer positive 33.Mumsreported happier moods while interacting with their kids, compared to other experiences, but not whileengaging34in childcare. "This difference suggests that how mothers and fathersspend time with their children might have important35forthein wellbeing,"the authors write They suspect that mums may be less happy than dads because they're more likelyto havehigher expectations about parenthood, As such, they're more likely to be "let down” by the experience.A) additionalI) implicationsB) associatedJ) interferedC) composingK) involvingD) cultivateL) noteE) depressiveM) preciselyF) directlyN) superficialG) emotionsO) thereforeH) however第一套选词填空答案：26.

Three days later you're overwhelmed by how much is on your todo list we become frustrated by our obligations even though we were the ones who said "yes" to them in the first place, Even worse, people will occasionally fightto do things that waste time. You don't have to do something just because it exists.It's worth asking if things are necessary. Many of them are not, and a simple"no will be more productive than whatever work the most eficient person can cope with. Butifthe benefits ofsaying "no" are so obvious, then why do we say "yes" so ofien?[C]We say "yes"to many requests not because we want to do them, but because we don't wanto be seen as rude or unhelpful. Often, we have to consider saying "no" to someone we will interact withagaininthe futureour co-worker, our spouse, our family and friends. Saying“no”to our superiors at work can be particularly difficult. In these situations, I like the approachrecommended in Essentialism by Greg MeKeown. He writes, "Remind your superiors what you would be neglecting if you said 'yes'and force them to deal with the trade-off. For example, if your manager comes to you and asks you to do X, you can respond with"Yes,I'm happy to make this the priority. Which of these other projects should l deprioritize to pay attention to this newproject?"[D]Collaborating with others is an important element of life. The thought of straining the relationship outweighs the commitment of our time and energy. For this reason, it can bo helpful to be gracious in your response. Do whatever favors you can, and be warm-heartecand direct when you haveto say no.Bt even afer we have accounted for these sociah onsderationsayofusstl seem to do a poor jos ofmaniting the tade of between yes andnoWe find ourselves overcomnitted to things that don't mcuningfully improve oe suppo those sround us, and cerainly don't improve our own lives.hott E1Perhaps ne issue is how we think about the meaning of yes and no. The words "yes" and get so ofren used in comparison with each oter that it feels like they carry cqual weigh in convesaion.in realitythey're not just opposite in meaning, but of entircly diterent magnitudes in commitment When you say"no", you're only saying "no" to one option When you say"yes" you're ssying"no"to every ather option, I like how cconomin Tim Harford putit"Every time we say"yes’to arequest, we're also saying "no" to anything clse we might accomplish with the time."Once you're committed to something, you've already decided how that future block oftime will be spent in other words, saying "no" saves you time in the fature. Saying"yes"costs you time in the future. “No" is a form of time credi. ou retain the ability to spend your future time however you want. *Yes is a form of tim debt You have to pay back your commitment at some point.[F]“No” is adecision.“Yes"is aresponsibility. Saying "no" is sometimes seen as a luxury thatonly those in power can afford. And its true: tuming down opportunities is casier when you can fall back on the safety net provided by power money, and authonty But it's also true that saying“no" is not merely a privilege reserved for the successful. it's also a strategy that an help you become successful. Saying"no" is an important skill to develop at any stage c your career because it retains the most important asset in life: your time. As investor Pedro Sorrentino put it,"If you don't guard your time, people will steal it from you." You need to say“no" to whatever isn't leading you toward your goals.[G]Nobodyembodied this idea better than Steve Jobs, who said, "People think focus means saying"yes'to thethingyou'vegot to focus onBut that's not what it means at all It means saying"no'tothehundred othergood ideas that there are. You have to pick carefully" Jobs had ano thergreat quote about saying“no":“T'm actually as proud of the things we haven't done as thethings Ihave done. Innovation is saying "no'to 1,000 things.[H]Overtime,asyou continueto improve and succeed, your strategy needs to change. The opportunity costofyourtime increases as you become more successful. At first, you just eliminate the obvious distractions and explore the rest. As your skills improve and you learn to separate what works from what doesn't, you have to continually increase your threshold for saying“yes"You still need to say“no”todistractions, but you also need to learn to say“no"to opportunities that were previously good uses of time. so you can make space for better uses oftime. It's a good problem to have, but it can be a tough skill to master.What is true about heaith ao true about pooductivity: an ounce ofprevertion is worth a pound ofcureMore effor is wasted doing things that don't matter than is wasted doing thingsineiciently And ifthat is the case, elimination is a more aseful skil thar optimization.Im reminded ofthe famous Peter Drucker quote, "There is nothing so useless doing eficiently that which should not be done at all."36.People often grant a request just beouuse they want to appear polite and helprul,37.sno casy job leaning to say"noto opportunities that were once considered wort grasping38.When you decline a request, you are saving your future time.39.People sometimes struggle to do things that are simply a waste oftime.40.Doing eficiently what is not worth doing is the most useless effort.41.Iis especially dificult for people to decline to do what their superiors ask them to do.42.

body needs to rest.Sleep is necessary for good health.During this time,the body recovers from the activities of the previous day.The rest that you get while sleeping enables your body to prepare itself for the next day. There are four levels of sleep,each being a little deeper than the one before.As you sleep,your muscles relax little by little.Your heart beats more slowly,and your brain slows down.After you reach the fourth level,your body shifts back and forth from one level of sleep to the other.Although your mind slows down,from time to time you will dream. Scientists who study sleep state that when dreaming occurs,your eyeballs begin to move more quickly(Although your eyelids are closed).This stage of sleep is called REM,which stands for rapid eye movement.If you have trouble falling asleep,some people recommend breathing very deeply.Other people believe that drinking warm milk will help make youdrowsy.There is also an old suggestion the counting sheep will put you to sleep!1.A good title for this is____.A.SleepC.DreamsB.Good HealthD.Work and Rest2.The word drowsy in the last paragraph means____.A.sickC.asleepB.stand upD.a little sleepy3.This suggests that not getting enough sleep might make you_____.A.dream more often C.nervousB.have poor health D.breathe quickly4.During REM,____.A.your eyes move quickly C.you are restlessB.you dreamD.both A and B5.The average number of hours of sleep that an adult needs is______.A.approximately six hoursB.around ten hoursC.about eight hoursD.not stated here四、书面表达：草拟一份中学通知，用一段话说明以下要点：参观日期：5月25日，星期天时间：早上8点钟出发。

The finding suggest that just as a parent's personality can affect the personality of a child, the same is true for a cat and its owner. Owners to find as individuals with high levels of anxiety, fear, anger, depression, and loneliness were more likely to have anxious, behavioral issues. Such cats displayed more aggressive and anxious behavioral styles as well as more stress related sickness. They were also more likely to have an ongoing medical condition and be overweight.The research also found that mentally well adjusted voters had calmer, happier, and healthier cats. The researchers explained that many owners regard their pets as a family member and form close social bonds with them. (17) The majority of owners want to provide the best care for their pets and is therefore possible that pets could be affected by the way their owners interact with and manage them. The study highlights an important relationship between our personalities and the well being of our pets. (18) Further research is needed to investigate the cause or nature of this relationship, and tolook at how owners’ personalities are directly influencing their pets behavior and well being. It is possible that the well being a pet is driven by the underlying nature of the owner, not simply by their conscious decisions and behaviors.Questions 16 to 18 are based on the passage you have just heard. Question 16. What do we learn from the new study by the university of Lincoln?Question 17. What does the passage say most pet owners want to do?Question 18. What does the passage say is still needed to understand the effects of owners personalities on their pets?【P a s sa g e2】(19)160 minute run can add 7 hours to your life. This was a claim made by the times last week. The claim was based on a new review of studies about the effects of running. The review concluded that on average, runners live 3 years longer than not runners, and that running does more to extend life than any other form of exercise. But there's more to running than its health benefits. (20)Research published in recent years has shown that running changes your brain and mind in some fascinating ways from increasing your brain function to regulating your emotions.However, the precise effects vary according to whether you engage in short, fast running or long distance running. For example, in one study, researchers compared participants ability to learn new words after several minutes of intense running and after 40 minutes of gentle running, participants were able to learn 20 % faster after the intense running. They showed a superior memory when tested again a week later. (21)In another study, researchers asked volunteers to jog for 30 minutes and then show them clips from a sad movie. Participants who usually struggled to handle negative emotions were more intensely affected by the sad clips, just as you expect, but crucially, this was less. So it happened.Questions 19 to 21 are based on the passage you just heard. Question 19. What does the new review of studies claim? Question 20. What is one effect that running has on people according to recent research?Question 21. What did another study find about the participants after they had a 30 minute jog?【P a s sa g e3】Welcome to the tour of the Hill House. This house, built in 1904, is one of the most well known works of Charles Hill, the famousarchitect. It was designed and built for a local entrepreneur at his family.(22) Before starting the tour, let me give you a brief introduction about the design of this amazing building. (23) Prior to beginning his design, the architect spent some time in the client's old home, observing their life and studying their habits. This meant that he could design the house according to the needs of the family.(24) The client's main desire was to have a home with a unique design. So the architect was given complete freedom.The building style is radically different from what was the fashion of the period. At the time, most large homes were constructed of timber and brick. This one, however, is made of concrete, a novel construction material in those days. The interior of the house, including fittings and furniture, was also designed by the same person. Most of the furniture you will see is original and in good condition. (25) However, those pieces in the children's bedrooms are copies, built to the designs of the architect. Fortunately, all the blueprints for both the building and its contents have been preserved. So we've been able to replace badly damaged furniture. Let's begin our tour starting from the rooms.Questions 22 to 25 are based on the passage you have just heard.Question 22: What do we learn about the speaker?Question 23: What did the architect do before beginning his design? Question 24: What did the architect’s client mainly want? Question 25: What do we learn about the pieces of furniture in the children's bedrooms?四级听力参考答案第一套1.

Lastly, as the selection of contestants, I suppose every student in our school could submit application but we should have an interview of first around and define the final 10 competitors.I hope the suggestions above would be useful and practical for you. For any question on the proposal, please feel free to write to me.Yours,Li Hua 第三套【Directions】Suppose you have just participated in a school project of collecting used books on campus.

沪江英语绿宝书之2010年12月大学英语四级考试参考答案Part ⅠWritingHow Should Parents Help Children to be IndependentNowadays, there is a growing concern over such a phenomenon, that is, some parents take care of almost everything concerned with their children, including study, work, marriage. Some parents believe that this is love, however, it is only to destroy children’s independence thoroughly.For the future of the next generation, more efforts should be made by parents to help their children to be independent. The fundamental one is to cultivate the awareness, namely, the importance and necessity of being independent, which is supposed to begin from childhood. Children should be taught that no one can be stronger and more helpful than themselves in this world.The quality of independence is so indispensable for us that parents had better act as a tutor, not a dictator. And only with parents’ trust, can the next generation accumulate confidence step by step.今年的作文主题非常贴近考生的生活，给了考生很大的发挥空间，擅长写日常生活细节的学生可以写上三五个句子勾勒父母对于子女的过度关爱，而擅长逻辑思考的学生则可以更多地阐述父母怎样的行为才可以培养子女独立的品格，而过度宠爱正导致了独立精神的消失。
从具体操作的角度来说，对于基础较为薄弱的考生，这次的考试题目是比较容易套用模板的，第一段，把现实状况描述清楚；第二段，写清楚父母亲帮助子女独立的策略；第三段，呼吁父母亲多给自己一些自由。
怎样解决(解决方案的优缺点)沪江考前模板专题里面关于解决问题类作文提到了类似的结构：In recent days, we have to face a problem-----A, which is becoming more and more serious.--------(说明A的现状)．Confronted with A, we should take a series of effective measures to cope with the situation. For one thing, ---------------(解决方法一). For another -------------(解决方法二). Finally, --------------(解决方法三).Personally, I believe that -------------(我的解决方法). Consequently, I’m confident that a bright future is awaiting us because --------------(带来的好处).像这样子的模板能够帮助无话可说，或者说英语表达能力比较弱的同学迅速找到思路，只需要填入关键的字词就可以完成作文。
但是对于能够用流畅的英语表达自己的思路的同学来说，写作如果希望取得比较高的分数，则需要注意语言必须尽可能简洁才能够在规定字数以内说清楚自己的论点，而句子的表达要求，也从有话可说，上升到言之有理，甚至上升到语言精致优美，内在逻辑严密的高度了。
在我们给出大家的这篇范文里面，三段文字结构清晰，语言简明优美又没有落入模板的窠臼，属于在临场作文中的优秀之作。

5．B) Provide more green spaces for them.解析：对应第八段内容，作者通过否定患儿对药物的依赖性来给出自己的建议，结合全文主旨自然环境的重要性，得出B答案6．B) They enjoy a life of better quality.解析：第九段第二句点出老龄人口增长的侧重点是在高质量的生活水平上，紧接着又指出绿色的生活方式是达到该种高质量生活水平的最重要因素。
7．C) access to nature contributes to the reduction of violence解析：十一段引文中can reduce violent behavior，直接对应C选项8．separated解析：题干是有关人们错误观念的问题，找到倒数第三段的关键段error引导的内容，再对应到humanity and the natural world，得出separated(照抄原文separable 与can重复，separable本身词义即能够分离的)9．the wild world解析：最后一段第二句直接命中题干，照抄the wild world即可。
