You may not use any of the words in the bank more than once.The pacific island nation of Palau has become home to the sixth largest marine sanctuary in the world. the new marine reserve.Now the largest in the pacific, will 26 no fishing or mining.Palau also established the worlds first shark sanctuary in 2009.The tiny island nation has set aside 500,000 square kilometres-80 percent-of its maritime27 ,for full protection that s the highest percentage of an28 economic zone devoted to marine conservation by any country in the world. the remaining 20 percent of the palau seas will be reserved for local fishing by individuals and small-scale29 fishing businesses with limited exports.island 30- have been among the hardest hit by the threats facing the ocean, said President Tommy Remengesau jr. in a statement. creating this sanctuary is a bold move that the people of Palau recognise as31 to our survival. we want to lead the way in restoring the health of the ocean for future generations.Palau has only been an32 nation for twenty years and has a strong history of environmen-tal protection.it is home to one of the worlds finest marine ecosystems, with more than 1, 300 species of fish and 700 species of coral.Senator Hokkons Baules lead 33- of the Palau National marine sanctuary act, said the sanctuary willhelp build a34 future for the palauan people by honoring the

in this section, you an going to read a passage with ten statements attached to it each statement contains information given in ine of the paragraphs.identify theparagraph from which the information is derived. you may choose a paragraph more than once. each paragraph is marked with a letter. answer the questions by marking the correspanding letter on answer sheet 2Data sharing: an open mind on open dataA it is a movement building steady momentum: a call to make research data, software code and experimental metbods publicly availablc and transparent A spirit of openness is gaining acceptance in the science community, and is the only way, say advocates, to address acrisis in science whereby too few findings are successfully reproduced. furthermore, they say, it is the best way for researchers to gather the range of observations that are necessary to speed up discoveries or to identify large-scale trendsb the open-data shift poses a confusing problem for junior researchers,on the one hand, the drive to share is gathering official steam. since 2013, global scientific bodies have begun to that support increased public access to research on the other hand, scientists disagree about how much and when they should share data, and they debate whether sharing it is more likely to accelerate science and make it more robust, or to introduce vulnerabilities andproblems. as more joumals and funders adopt data-sharing requirements, and as a growing number of enthusiasts call for more openness.junior researchers must find their place between adopters and those who continue to hold out, even as they strive to launch their own careers.( c) one key challenge facing young scientists is how to be open without becoming scientifically vulnerable. they must determine the risk of jeopardizing a job offer or a collaboration proposal from those who are wary of -or unfamiliar with -open science. and they must learn how to capitalize on the movements benefits, such as opportunities for more citations and a way to build a reputation without the need for conventional metrics, such as publication in high-impact journals.D some fields have embraced open data more than others. researchers in psychology, a field rocked by findings of irreproducibility in the past few years, have been especially vocal supporters of the drive for more-open science. a few psychology journals have created incentives to increase interest in reproducible science-for example, by affixing an badge to articles that clearly state where data are available. according to social psychologist brian nosek,executive director of the center for open science, the average data-sharing rate for the joumal Psychological science, which uses the badges, increased tenfold to 38% from 2013 to 2015.E funders, too, are increasingly adopting an open-data policy several strongly encourage,and some require a data-management plan that makes data available. the ional scienc Foundation is among these. some philanthropic(&)funders, including the bill &melinda Gates foundation in seattle, washington, and the wellcome trust in london, also mandate open data from their grant recipients.F but many young rescarchers,especially those who have not been mentored in open science are uncertain about whether to share or to stay private. graduate students and who often are working on their lab heads grant, may have no choice if their supervisor or another senior colleague opposes sharing.G some fear that the potential impact of sharing is too high, especially at the early stages of a career Everybody has a story about soneone getting scoopedsays New York university astronomer david hogg. those fears may be a factor in a lingering hesitation to share data even when publishing in journals that mandate it.H researchers at small labs or at institutions focused on teaching arguably have the most to lose.when sharing hard-won data. with my institution and teaching load, i dont have postdocs and grad students, says terry mcglynn, a tropical biologist at california state university,Dominguez hills. the stakes are higher for me to share data because its a bigger fraction of whats happening in my lab.I researchers also point to the time sink that is involved in preparing data for others to view Once the data and associated materials appear in a repository( 存储库), answering questions and handling complaints can take many hour.J the time investment can present other problems. in some cases, says data scientist karthik Ram, it may be difficult for junior researchers to embrace openness when senior colleagues many of whom head selection and promotion committees-might ridicule what they may view as misplaced energies i have heard this recently that embracing the idea of open data and code makes traditional academics uncomfortable, says ram. the concem seems to be that open advocates dont spend their time being as productive as possibleKan open-science stance can also add complexity to a collaboration. kate ratliff, who studies social attitudes at the university of florida, gainesville, says that it can seem as if there are two camps in a field-those who care about open science and those who dont there is a new area to navigate-are you cool with the fact that ill want to make the data open?-when talking with somebody about an interesting research idea, she says.L despite complications and concerns, the upsides of sharing can be significant. for example, when information is uploaded to a repository, a digital object identifier(DOI) is assigned.Scientists can use a doi to publish each step of the research life cycle, not just the final paper In so doing, they can potentially get three citations- one each for tthe data and software,inaddition to the paper itself. and although some say that citations for software or data hace little currency in academia, they can have other benefitsMmany advocates think that transparent data procedures with a date and time stamp will protect ientists from being scooped. this is the sweet spot between sharing and getting credit for it.while discouraging plagiarism says lvo Grigorov a project cooedinator at thenational institute of aquatic resources research secretariat in charlottenlund, denmark. hogg.says that scooping is less of a problem than many think. the two cases im familiar with didnt involve open data or code, he says.N open science also offers junor researchers the chance to level the playing field by gaining better access to crucial data .rose mounce a postdoc studing ecolutionary biology at the University of cambridge, uk, is a vocal champion of open science, partly because his fossilbased research depends on access to others data. he says that more openness in science could help to discourage what some perceive as a common practice of shutting out early-career scientists requests for data.Ocommunication also helps for those who worry about jeopardizing a collaboration, he says Concems about open science should be discussed at the outset of a study. whenever you start a project with someone, you have to establish a clear understanding of expectations for who owns the data, at what point they go public and who can do what with them, he says.P in the end, sharing data, software and materials with colleagues can help an early-career researcher to gain recognition-a crucial component of success. the thing you are searching for is reputation, says titus brown, a genomics(基因组学) researcher at the university of California, davis.to get grants and jobs, you have to be relevant and achieve some level of public recognition. anything you do that advances your presence - especially in a larger sphere, outside the communities you know-is a net win.36. astronomer david hogg doesnt think scooping is as serious a problem as generally thought.37. some researchers are hesitant to make their data public for fear that others might publish nething similar before them.38.some psychology journals have offered incentives to encourage authors to share their data39. there is a growing demand in the science community that research data be open to the public40. sharing data offers carly career researchers the chance to build a certain level of reputation.41.data sharing enables scientists to publish each step of their research work, thus leading to more citations.42. scientists hold different opinions about the extent and timing of data sharing43. potential problems related to data sharing should be made known to and discussed by all participants at the beginning of a joint research project44. sharing data and handling data-related issues can be time-consuming45. junior researchers may have no say when it comes to sharing dataSection cPassage oneQuestions 46 to 50 are based on the following passage.In the beginning of the movie / robot a robot has to decide whom to save after two cars plunge into the water-del spooner or a child. even though spooner screamssave her save her.the robot rescues him because it calculates that he has a 45 percent chance of survival compared to sarahs ll percent. the robots decision and its calculated approach raise an important question:would humans make the same choice and which choice would we want our robotic counterparts to make?Isaac asimov evaded the whole notion of morality in devising his three laws of robotics, which hoId that I. robots cannot harm humans or allow humans to come to harm; 2. robots must obey preservation, unless doing so conflicts with laws i or 2. these laws are programmed into Asimovs robots-they dont have to think, judge, or value. they don t have to like humans or believe that hurting them is wrong or bad. they simply dont do it.The robot who rescues Spooners life in i, robot follows Asimovs zero law: robots cannot harm humanity (as opposed to individual humans or allow humanity to come to harm-an expan-sion of the first law that allows robots to determine whats in the greater good. under the first law.a robot could not harm a dangerous gunman, but under the zero law, a robot could kill the gunman to save others.Whether its possible to program a robot with safeguards such as asimovs laws is debatable A word such asharmis vague (what about emotional harm? is replacing a human employee harm?)and abstract concepts present coding problems. the robots in asime complications and loopholes in the three laws, and even when the laws work, robots still have to asscss situations.Assessing situations can be complicated. a robot has to identify the players, conditions, and possible outcomes for warious scennrios. Its doubtful that a computer program can do that-at least, not without some undesirable results. A robotocost at the bristol robotics laboratory programmed a robot to save human proxies(替身)called“Hbots”from danger. when one H-bot of headed for danger,the robot sucecssfully pushed it out the way. but when two h-bots became imperiled, the robot choked 42 percent of the time, unable to decide which to save and letting them both die .The robot choked 42 percent of the time, unable to decide which to save and letting them headed for danger, the robot successfully pushed it.how can
