For example,as many as1,125viable seeds per square meter were found in a100-year-old Douglas fir/western hemlock forest in coastal British Columbia.Nearly all the seeds that had germinated from this seed bank were from pioneer species.The rapid colonization of such sites after disturbance is undoubtedly in part a reflection of the largeseed band on the forest floor.④An adaptation that is well developed in colonizing species is a high degree of variation in germination(the beginning of a seed’s growth). Seeds of a given species exhibit a wide range of germination dates, increasing the probability that at least some of the seeds will germinate during a period of favorable environmental conditions.This is particularly important for species that colonize an environment where there is no existing vegetation to ameliorate climatic extremes and in which there may be great climatic diversity.⑤Species succession in plant communities,i.e.,the temporal sequence of appearance and disappearance of species is dependent on events occurring at different stages in the life history of a species. Variation in rates of invasion and growth plays an important role in determining patterns of succession,especially secondary succession. The species that are first to colonize a site are those that produce abundant seed that is distributed successfully to new sites.Such species generally grow rapidly and quickly dominate new sites, excluding other species with lower invasion and growth rates.The first community that occupies a disturbed area therefore may be composed of specie with the highest rate of invasion,whereas the community of the subsequent stage may consist of plants with similar survival ratesbut lower invasion rates.译文植物定居①定居是植物改变一个地点生态环境的一种方式。

You may choose a paragraph more than once.Each paragraph is marked with a letter.Answer the questions by marking the corresponding letter on Answer Sheet2.Take Naps at Work.Apologize to No One[A]In the past two weeks I’ve taken three naps at work,a total of an hour or so of shut-eye while on the clock.And I have no shame or uncertainty about doing it.I couldn’t feel better about it,and my productivity reflects it,too.[B]Sleeping on the job is one of those workplace taboos-like leaving your desk for lunch or taking an afternoon walk-that we’re taught to look down on.If someone naps at2p.m.while the rest of us furiously write memos and respond to emails,surely it must mean they’re slacking off(偷懒).Or so the assumption goes.[C]Restfulness and recharging can take a back seat to the perception and appearance of productivity.It’s easier to stay on a virtual hamster(仓鼠)wheel of activity by immediately responding to every email than it is to measure aggregate productivity over a greater period of time.But a growing field of occupational and psychological research is building the case for restfulness in pursuit of greater productivity.[D]Companies are suffering from tremendous productivity problems because people are stressed out and not recovering from the workday,said Josh Bersin,Principal and Founder of Bersin by Deloitte.“They’re beginning to realize that this is their problem,and they can’t just say to people,‘Here’s a work-life balance course,go teach yourself how to manage your inbox,’”Mr.Bersin said.“It’s way more complicated than that.”[E]To be sure,the ability to nap at work is far from widespread,experts said.Few among us have the luxury of being able to step away for a half-hour snoozefest.But lunch hours and coffee breaks can be great times to duck out,and your increased productivity and alertness will be all the evidence you need to make your case to inquiring bosses.[F]In an ideal world,we’d all solve this problem by unplugging early and getting a good night’s sleep. Here’s our guide on how to do just that.But the next best thing is stealing away for a quick power nap when you’re dragging after lunch.[G]In a study published in Nature Neuroscience,researchers tested subjects on their perceptual performance four times throughout the day.Performance deteriorated with each test,but subjects who took a30-minute nap between tests stopped the deterioration in performance,and those who took a60-minute nap even reversed it.[H]“Naps had the same magnitude of benefits as full nights of sleep if they had a quality of nap.”said Sara Mednick,a co-author of the study and associate professor of psychology at the University of California,Riverside.[I]Dr.Mednick,a sleep researcher and the author of Take a Nap!Change Your Life,said daytime napping can have many of the benefits of overnight sleep,and different types of naps offer specific benefits.[J]For example,Dr.Mednick said a20-to60-minute nap might help with memorization and learning specific bits of information.It’s just long enough to enter stage-two sleep,or non-rapid eye movement(R.E.M.)sleep.[K]After60minutes,you start getting into R.E.M.sleep,most often associated with that deep,dreaming state we all enjoy at night R.E.M.sleep can improve creativity,perceptual processing and highly associativethinking,which allows you to make connections between disparate ideas,Dr.Mednick said.Beyond that,your best bet is a90-minute nap,which will give you a full sleep cycle.[L]Any nap,however,can help with alertness and perception and cut through the general fog that creeps in during the day,experts said.[M]So how did we even arrive at this point where aptitude is inextricably tied(紧密相连)to working long, concentrated hours?Blame technology,but think broader than smartphones and laptops;the real issue is that tech has enabled us to be available at all times.[N]“We went through a period where people were in denial and business leaders were ignoring it,”Mr. Bersin said.“They were assuming that if we give people more tools,more emails,more Slack,more chatter,and we’ll just assume they can figure out how to deal with it all.And I think they’ve woken up to the fact that this is a big problem,and it is affecting productivity,engagement,health,safety,wellness and all sorts of things.”[O]It isn’t just office workers who can benefit from an afternoon siesta(午睡).A2015study published in Current Biology looked at the at the sleeping habits of three hunter-gatherer preindustrial societies in Tanzania, Namibia and Bolivia.[P]“They’re active in the morning,then they get in the shade under the trees and have a sort of quiet time, but they’re not generally napping,”said Jerome Siegel,professor of psychiatry and biobehavioral sciences,and director of the U.C.L.A.Center for Sleep Research,a co-author of the study.“Then they do some work and go to sleep,and they sleep through the night.”[Q]Still,Mr.Siegel said,“the only genuine way to solve daytime sleepiness and fatigue starts the night before with a solid night’s sleep.”The real Holy Grail of restfulness is a regular sleep schedule with ideally seven or eight hours of sleep each night,which experts say is optimal.[R]“Daytime napping certainly does increase alertness,”Mr.Siegel said.“But it’s not as simple as going to the gas station and filling the tank.”[S]He also advises avoiding caffeine late in the day and waking around the same time every morning,even if you can’t get to sleep at the same time every night,This helps acclimate(使适应)your body to your regular wake-up time,regardless of how much sleep you got the night before.[T]So if you’ve made it this far and you’re interested in giving workday naps a try(or just starting to nod off),here’s a quick guide to the perfect nap;Find a quiet,unoccupied space where you won’t be disturbed.Try to make your area as dim as possible(or invest in a sleep mask you can keep in the office).Earplugs might help.too.Aim for around20minutes.Any longer than that and you’re likely to wake up with sleep inertia(睡眠惰性)，which will leave you even groggier(头脑昏沉的)than before.36.Participants’perceptual performance became better after sleeping one hour between tests in an article inNature Neuroscience.37.Jerome Siegel found that only by sleeping soundly through the previous night could people tackle theirweariness during the day.38.Our talent is closely bound to working with concentration for long periods of time because technologymakes us accessible24/7.39.Taking a nap at work is normally regarded as laziness that should be held in contempt and avoided inworkplace.40.Between20to60minutes,people can get into non-REM sleep which may improve memory and learningability according to Dr.Mednick.41.People can doze off at lunch and coffee breaks and defended themselves by saying their improvedproductivity and alertness when bosses investigated their whereabouts.42.The author’s tips on taking a perfect nap involve sleeping place,environment and duration.43.The author believes business leaders are aware that availability at any time due to technology has negativeeffects on every aspect of people’s life.44.The optimal length of a nap was an hour and a half so that people could go through a complete sleep cycle.45.Josh Bersin mentioned the cause of companies’big productivity problems and the solution which needsmore that just employees’efforts.Section CDirections:There are2passages in this section.Each passage is followed by some questions or unfinished statements.For each of them there are four choices marked A),B),C)and D).You should decide on the best choice and mark the corresponding letter on Answer Sheet2with a single line through the centre.Passage OneQuestions46to50are based on the following passage.Every office worker hates meetings.But it’s a strange sort of hate,similar to the hatred of Londoners for the Northern Line,or New Yorkers for tourists who walk too slowly:the dislike is real,yet if the despised thing were to vanish,it’d be like surrendering a piece of your soul.When researchers probed into why people put up with the strain that meetings place on their time and sanity, they found something-those who resent and dread meetings the moat also defend them as a“necessary evil”, sometimes with great passion.True,research suggests that meetings take up vastly more of the average manager’s time than they used to.True,done badly,they’re associated with lower levels of innovation and employee wellbeing(幸福).But that’s just office life,right?It’s not supposed to be fun.That’s why they call it work.Underlying(引起)this attitude is an assumption that’s drummed into us not just as workers but as children, parents and romantic partners;that more communication is always a good thing.So suggestions abound for(大量存在)communicating better in meetings-for example,hold them standing up,so speakers will come to the point more quickly.But even when some companies consider abolishing meetings entirely,the principle that more communication is better isn’t questioned.If anything,it’s reinforced when such firms introduce“flat”management structures,with bosses always available to everyone,plus plenty of electronic distraction.In fact,constant connectivity is disastrous for both job satisfaction and the bottom line.And anyway,once you give it three seconds’thought,isn’t it cleat that more communication frequently isn’t a good thing?Often,the difference between a successful marriage and a second-rate one consists of leaving about three or four things a day unsaid.At work,it’s surely many more than four,though for a different reason;office communication comes at the cost of precisely the kind of focus that’s essential to good work.Yet we’re so accustomed to seeing talking as a source of solutions-for resolving conflicts or finding new ideas-that it’s hard to see when it is the problem.46.What does the author say about meetings?A)Londoners hate them as well as the Northern Line.B)They can help to keep workers’physical and spiritual health.C)Workers might be reluctant to give up them completely.D)New Yorkers dislike meetings more than Londoners.47.What did researchers find about people’s attitude towards meeting?A.Their attitude and behavior are paradoxical.B)People who hate meetings the most are senior insane.C)Those who like meetings might be considered insane.D)More meetings are regarded as a sign of less innovation.48.Why do people think that more communication is always a good thing?A)Because the concept is firmly believed by workers.B)Because everyone loves to communicate with others.C)Because the idea has been instilled into people’s mind.D)Because communication is vital for building relationships.49.What does the author think of the“flat”management structure?A)It forces bosses to frequently contact their employees.B)It helps to soften employees’bottom line of work.C)It is definitely a disaster to employees’job satisfaction.D)It strengthens people’s deeply-rooted notion of communication.50.What is the author’s argument about office communication?A)It is an effective way to solve office conflicts.B)It affects work efficiency in a negative way.C)It should come to a halt at intervals.D)It is useful for workers to find new ideas.Passage TwoQuestions51to55are based on the following passage.The Internet has enabled the spread of information at lightning speed.This information revolution has created tremendous business opportunities for online publishers,but not all of them maintain proper quality-control mechanisms to ensure that only good information is being shared.Instead,many publishers aim simply to make money by whatever means possible,with no regard for the implications for society at large.When selfish publishers set up shops online,the primary goal is to publish as much as possible,often at the cost of quality.In this respect,many publishers start numerous online journals focused on overlapping(重叠的)disciplines—to increase their total number of published papers—and hire young business managers who do not have any experience in either science or publishing.In some cases,online publishers even give up peer review, while still presenting themselves as scientific journals—deception designed to take advantage of scientists who simply want to share their research.If publishers structure their business to make more revenue,it often does harm to their products.When publishers start journals with overlapping domains,in combination with the pressure to publish more studies,this could promote the publication of marginal or even questionable articles.Moreover,publishers with multiple overlapping journals and journals with very narrow specialties(专业)increase the demands on the time and efforts of willing reviewers.With the fact that reviewers are generally not compensated for their time and effort,journal editors are often unable to find enough reviewers to keep up with the increased publication rate.To improve the situation and increase the trust in scientific community,the pressure to publish must be reduced.Funding and promotion decisions should not be based on the number of publications,but on the quality of those publications and a researcher’s long-term productivity and instructions.And that’s just the start.We need additional mechanisms,such as Beall’s list of predatory(掠夺的)publishers, to alert scientists to fake journals and fake articles.In addition,the price for online publication must be controlled and a mechanism must be put in place to honor and reward hard-working reviewers.51.What does the author think of online publishers?A)A small proportion of them can guarantee their publishing quality.B)They have lots of opportunities to renovate their business models.C)Many of them tend to try every means to make a buck.D)Social impact is their first priority when publishing books.52.It can be inferred from the second paragraph that______.A)peer review generally is a criterion to identify academic journalsB)researchers focus their research on the combination of disciplinesC)scientists care about their publications rather than researchD)young business managers are willing to face new challenges53.Why can’t publishers find enough reviewers to review papers?A)Reviewers are pressed for time when reviewing articles.B)Reviewers’gains can’t make up for what they have done.C)Publishers may compel reviewers to accept marginal articles.D)Publishers urge reviewers to increase publication rate rapidly.54.What is the author’s suggestion for online publication?A)More weight should be put on the quantity of publications.B)It is worthwhile to reward diligent reviewers for their effort.C)Fake journals should be reported to a regulatory organization.D)The price of online publication should be lowered greatly.55.What is the main idea of this passage?A)Online publishers should take measures to fight against fake scientific journals.B)Online publishers are pursuing their work efficiency at the cost of quality.C)Online publishers business models are quite likely to harm their publications.D)Online publishers are sacrificing the quality of research articles to make money.PartⅣTranslation(30minutes)Directions:For this part,you are allowed30minutes to translate a passage from Chinese intoEnglish.You should write

AI and Robotics The Dawn of a New Era
AI and Robotics The Dawn of a New Era AI and robotics have ushered in a new era of technological advancement, revolutionizing the way we live and work. While these innovations offer numerous benefits, they also raise significant ethical and societal concerns. As wenavigate this new frontier, it is crucial to consider the implications of AI and robotics from multiple perspectives, including their impact on the workforce, privacy, and human relationships. One of the most pressing issues surrounding AI and robotics is the potential displacement of human workers. As automation becomes increasingly sophisticated, many fear that jobs will be lost to machines, leading to widespread unemployment and economic instability. This concern is not unfounded, as studies have shown that certain industries, such as manufacturing and transportation, are particularly vulnerable to automation. However, it isimportant to recognize that AI and robotics also have the potential to create new job opportunities and enhance productivity in existing roles. By taking on repetitive and dangerous tasks, machines can free up human workers to focus on more creative and complex responsibilities. Additionally, the development and maintenance of AI and robotic systems require a skilled workforce, presenting new career paths in engineering, programming, and maintenance. Therefore, while the impact of AI and robotics on employment is a valid concern, it is essential to approach this issue with a balanced perspective, considering both the potential challenges and opportunities. In addition to their impact on the workforce, AIand robotics also raise significant privacy concerns. As these technologies become more integrated into our daily lives, they have the potential to collect and analyze vast amounts of personal data. This data can be used to make decisions about individuals, ranging from targeted advertising to employment opportunities. Furthermore, the increasing autonomy of AI systems raises questions about accountability and transparency. Who is responsible when an AI makes a decisionthat harms an individual or violates their privacy? These concerns areparticularly relevant in fields such as healthcare and finance, where AI systems are increasingly used to make critical decisions. As we continue to integrate AI and robotics into various aspects of society, it is crucial to establish robust regulations and ethical guidelines to protect individuals' privacy and ensureaccountability for the actions of these technologies. Beyond their impact on the workforce and privacy, AI and robotics also have the potential to fundamentally alter human relationships and social dynamics. As these technologies become more advanced, they have the capacity to simulate human emotions and behaviors,blurring the line between man and machine. This raises profound questions about the nature of consciousness and the ethical implications of creating machines that mimic human cognition. Furthermore, the increasing reliance on AI and robotics for social interaction has the potential to erode genuine human connections and empathy. For example, the use of AI chatbots and virtual companions may provide a sense of companionship, but they cannot replicate the depth and complexity of human relationships. As we continue to develop AI and robotics, it is essential to consider the impact of these technologies on our social fabric and strive to maintain the authenticity and depth of human connections. In conclusion, the dawn of the AI and robotics era presents a myriad of opportunities and challenges that must be approached with careful consideration and ethical foresight. While these technologies have the potential to enhance productivity, improve healthcare, and revolutionize various industries, they also raise significant ethical and societal concerns. By examining the impact of AI and robotics from multiple perspectives, including their implications for the workforce, privacy, and human relationships, we can work towards harnessing the potential of these technologies whilemitigating their potential risks. It is essential to engage in open and inclusive discussions about the ethical and societal implications of AI and robotics, involving diverse stakeholders to ensure that these technologies are developed and utilized in a responsible and beneficial manner. As we navigate this new era, it is imperative to approach the integration of AI and robotics into our society with a thoughtful and balanced perspective, considering not only the technological advancements but also the human and ethical implications.。

餐厅规则英语作文带图画Dining Etiquette: A Guide to Proper Restaurant BehaviorDining out is a cherished social experience, allowing us to savor delicious cuisine, engage in stimulating conversation, and create lasting memories. However, to fully enjoy this experience, it is essential to adhere to proper dining etiquette. In this essay, we will explore the fundamental rules and guidelines that govern appropriate behavior in a restaurant setting.Arriving and Being SeatedPunctuality is key when dining out. Arriving on time, or even a few minutes early, demonstrates respect for the establishment and your dining companions. Upon entering the restaurant, greet the host or hostess politely and provide your reservation name or party size. If no reservation was made, patiently wait to be seated. When escorted to your table, express your gratitude and allow the host or hostess to pull out chairs for you and your guests.Ordering and Menu EtiquetteOnce seated, take a moment to review the menu and consider your selections carefully. Avoid rushed or impulsive decisions, as this canslow down the service and inconvenience your fellow diners. When ready to order, make eye contact with your server and speak clearly and concisely. If you have any dietary restrictions or preferences, communicate them politely to the server. Refrain from criticizing the menu or making excessive special requests, as this can be disruptive to the kitchen staff.Table Manners and Dining EtiquetteProper table manners are essential for creating a pleasant dining experience. Begin by placing your napkin on your lap, and keep it there throughout the meal. Avoid leaning on the table or reaching across it to retrieve items. Instead, politely ask your dining companions to pass the desired item. When eating, keep your elbows off the table and maintain good posture. Chew with your mouth closed, and avoid speaking with food in your mouth. If you need to excuse yourself during the meal, such as to use the restroom, do so discreetly and return to the table promptly.Handling UtensilsThe proper use of utensils is a hallmark of refined dining etiquette. Start from the outside and work your way inward as the courses progress. Use your knife and fork to cut food into bite-sized pieces, and avoid cutting more than one piece at a time. If a salad is served, use the salad fork, which is typically the smaller fork on the left side of your place setting. When finished with a course, place yourutensils on the plate in the "done" position, with the tines facing down and the handles resting at the 4 o'clock position.Handling Bread and CondimentsBread is a common accompaniment to many meals, and proper etiquette dictates that you should tear off small pieces, rather than biting directly from the roll or slice. Butter should be applied to one piece at a time, using the butter knife provided. Avoid double-dipping your bread in communal condiments, such as butter or dips, as this can spread germs. Instead, take a small portion of the condiment onto your plate and use your own utensil to apply it to your bread.Handling BeveragesWhen it comes to beverages, there are a few important rules to remember. First, avoid reaching across the table to access a shared pitcher or carafe. Instead, politely ask your dining companions to pass it to you. When drinking, take small sips and avoid slurping or making loud noises. If you need to take a sip during conversation, do so discreetly and avoid interrupting the flow of the discussion.Handling Smartphones and ConversationIn today's digital age, it's crucial to be mindful of the impact of technology on the dining experience. Refrain from using your smartphone during the meal, unless it is an emergency. Engage inlively conversation with your dining companions, avoiding topics that may be controversial or inappropriate for the setting. If you need to take a call or respond to a message, excuse yourself from the table and step away from the dining area.Tipping and GratitudeAt the end of the meal, remember to leave a suitable tip for your server, typically 15-20% of the total bill. This gesture of gratitude acknowledges the hard work and attentive service provided by the staff. Additionally, express your appreciation to the server and any other staff members who contributed to your dining experience.ConclusionAdhering to proper dining etiquette not only enhances the overall dining experience but also demonstrates respect for the establishment, your fellow diners, and the hard-working staff. By following these guidelines, you can ensure that your next restaurant visit is a memorable and enjoyable one, filled with delicious food, engaging conversation, and impeccable manners.。
