up the planet's largest mass of ocean plastic.The experts believe the machine should be able to collect half of the detritus in the patchabout 40,000 metric tonswithin five years.In the past few weeks they have been busy welding together giant tubes that will sit on the surface of the sea and form the skeleton of the machine，creating the largest floating barrier ever made.The system，originally dreamt up by Mr.Slat，will be shipped out this summer to the Great Pacific Garbage Patch，between Hawaii and California，which contains estimated 1.8 trillion pieces of plastic.It will be the first ever attempt to tackle the patch since it was discovered in 1997.Mr.Slat was 16 and still at school when he was diving in Greece and first saw for himself the amount of plastic polluting the sea.“There were more bags than fish down there，” he recalls.Two years later he came up with a solution，quit university after six months and set up The Ocean Cleanup as a company.Mr.Slat says the first plastic to arrive on shore will be a major milestone.“We as humanity created this problem，so I think it's also our responsibility to help solve it，” he says.The Great Pacific Garbage Patch(GPGP) covers an area of 1.6 million square kilometers and contains at least 79,000 tons of plastic，research found last month.Most of it is made up of “ghost gear”parts of abandoned and lost fishing gear，such as nets and ropesoften from illegal fishing vessels.Ghost gear kills more than 100,000 whales，dolphins and seals each year，according to scientific surveys.Seabirds and other marine life are increasingly being found dead with stomachs full of small pieces of plastic.Creatures eat plastic discarded in the sea thinking it's food but then starve to death because they are not feeding properly.Others are trapped and die of starvation or are strangled or suffocated by ghost gear.【語(yǔ)篇解讀】本文是一篇說(shuō)明文，主要介紹了世界首個(gè)海洋垃圾清掃機(jī)的發(fā)明。1What does the underlined word in the second paragraph probably

news. When we use AI，such tasks are based on “classification technology” in machine learning having the computer learn，using the boundary separating positive and negative data.For example，“positive” data would be photos including a happy face，and “negative” data photos that include a sad face.Once a classification boundary is learned，the computer can determine whether certain data are positive or negative.However，the difficulty with this technology is that it requires both positive and negative data for the learning process，and negative data are not available in many cases.For instance，when a retailer(零售商) is trying to predict who will make a purchase，they can easily find data on customers who have purchased from them (positive data)，but it is basically impossible to obtain data on customers who have never purchased from them(negative data)，since they do not have access to their competitors' data.According to lead author Takashi Ishida from RIKEN AIP，“Previous classification methods could not cope with the situation where negative data were not available，but we have made it possible for computers to learn with only positive data，as long as we have a confidence score for our positive data，constructed from information such as buying intention or the active rate of app users.Using our new_method，we can let computers learn a classifier only from positive data equipped with confidence.”According to Ishida，“This discovery could expand the range of applications where classification technology can be used.Even in fields where machine learning has been actively used，our classification technology could be used in new situations where only positive data can be gathered due to data regulation or business constraints(限制)In the near future，we hope to put our technology to use in various research fields，such as natural language processing，computer vision，robotics，and bioinformatics.”【語(yǔ)篇解讀】分類對(duì)我們的日常生活至關(guān)重要。然而在分類技術(shù)機(jī)器學(xué)習(xí)過(guò)程中，分類既需要積極的數(shù)據(jù)，也需要消極的數(shù)據(jù)，而消極的數(shù)據(jù)在很多情況下是很難獲得的。現(xiàn)在科學(xué)家能用分類技術(shù)使機(jī)器學(xué)習(xí)只識(shí)別積極的數(shù)據(jù)。5How can the computer distinguish the positive data from the negative data?ABy learning the classification boundary.BBy updating the data collected regularly.CBy separating happy faces and sad ones.DBy introducing classification technology.A細(xì)節(jié)理解題。根據(jù)第一段最后一句“Once a classification boundary is learned，the computer can determine whether certain data are positive or negative”可知，一旦學(xué)習(xí)了分類邊界，計(jì)算機(jī)就可以確定某些數(shù)據(jù)是積極的還是消極的，由此可知，計(jì)算機(jī)是通過(guò)學(xué)習(xí)分類邊界來(lái)區(qū)分積極數(shù)據(jù)和消極數(shù)據(jù)的。6Why is the example mentioned in Paragraph 2?ATo prove how important the positive data are.BTo confirm that data on customers are complete.CTo argue that retailers get their competitors' data.DTo explain why negative data are hard to acquire.D細(xì)節(jié)理解題。根據(jù)文章的第二段，尤其是第一句“However，the difficulty with this technology is that it requires both positive and negative data for the learning process，and negative data are not available in many cases”可知，在學(xué)習(xí)過(guò)程中，它既需要積極的數(shù)據(jù)，也需要消極的數(shù)據(jù)，而消極的數(shù)據(jù)在很多情況下是很難獲得的，進(jìn)而后面舉例說(shuō)明解釋了為什么消極的數(shù)據(jù)很難獲得。7What do the underlined words “new method” in Paragraph 3 refer to?AAnalyzing buying intention.BBuilding a confidence score.CAssessing the active rate of app users.DEquipping the computer with confidence.B推理判斷題。根據(jù)文章的第三段，尤其是畫(huà)線詞組前一句中的“but we have made it possible for computers to learn with only positive data，as long as we have a confidence score for our positive data，constructed from information such as buying intention or the active rate of app users”可推知，畫(huà)線詞組所在句表示使用這種建立信心指數(shù)的新方法，我們就可以讓電腦只用積極的數(shù)據(jù)來(lái)學(xué)習(xí)，故畫(huà)線詞組是指建立信心指數(shù)。8What can be a suitable title for the text?AThe History of Classification TechnologyBSmarter AI：Machine Learning Without Negative DataCBigger Data：Computers Assisting Language ProcessingDThe Comparison between Positive Data and Negative DataB標(biāo)題歸納題。通讀全文可知，分類對(duì)我們的日常生活至關(guān)重要。然而在分類技術(shù)機(jī)器學(xué)習(xí)過(guò)程中，分類既需要積極的數(shù)據(jù)，也需要消極的數(shù)據(jù)，而消極的數(shù)據(jù)在很多情況下是很難獲得的。現(xiàn)在科學(xué)家能用分類技術(shù)使機(jī)器學(xué)習(xí)只識(shí)別積極的數(shù)據(jù)。.完形填空(2019·福建省質(zhì)量檢查測(cè)試)Every year，the fifth graders at Brookstone Elementary School went on a field trip to Washington，D.C.

after he left.Outside，Steve flickered(閃爍) his bike light up toward the hospital.To his surprise，the teen responded，flickering his own room lights right back.Every night after that，Steve flickered his light，and more and more kids flickered back.When he mentioned it to a friend working at a restaurant，the owner said he wanted in too.He started to flicker the restaurant sign for one minute every night at 8：30.Soon enough，the customers started joining in with flashlights and cell phones.Almost by accident，a simple action was changing into a powerful connection between local people and sick children.Now more than 20 groups are on board for the 8：30 pm.flicker.Every Wednesday night，police officers line up their cars and flash them.Even boats on the river join in to give their bright good­night wave to kids who are going through frightening situations and sleeping in a strange place.“It is all I look forward to basically all day，” says Abigail Waldron，aged ten.“It just shows you that somebody is helping you through your whole experience in the hospital.”“It would be very hard not to do this，” says Steve，“once you start.” The most powerful of all，he adds，comes from the

1985，Johnny Jennings,86，has been selling newspapers and magazines to a recycling center with his son.By the time Jennings' only child was 17，he stopped joining his father.Even though his son is all grown up now，Jennings hasn't slowed down his efforts.In fact，he has turned his recycling money into something bigger.Jennings visits local churches and businesses to collect paper，which he brings to a recycling center for money.But instead of putting those earnings in his own bank account，he sends every dollar to Georgia Baptist Children's Homes & Family Ministries.Once a year，he'll give the organization a check somewhere between $10,000 and $35,000.By 2016，that tallied up to $400,000.These days，Jennings' recycling has turned into a community effort.After he has made his own rounds recycling paper from businesses and churches，he'll find more items waiting for him at home.Community members drop off other recyclables at his house so he can sell them，along with books，food，clothes，and other items to give away.Recycling centers typically pay just one­half to three cents per pound of paper，but Jennings' visits have added up the big time.In 2016 alone，he sold more than 400,000 pounds of paper and 51,000 aluminum cans(鋁罐)，and collected more than 32,000 pennies.Over the course of 32 years he has recycled more than 9.8 million pounds of paper，saving an estimated 79,000 trees in the process.Jennings says he'll continue raising money for charity as long as his health allows.【語(yǔ)篇解讀】文章講述了樂(lè)于助人的Johnny Jenni
