AThe backpack you take can make or break your trip when you go traveling.Here are the four best travel backpacks on the market.Amazon Basics70LIt's much cheaper than many travel bags on the market and does not sacrifice any of the practical uses or space that comes with more expensive bags.The bag may not be as luxury as some of the more high-end bags,but its simple style lets you focus on the main thing you need to focus on when traveling:the moment.Eurohike Nepal65LThe Eurohike Backpack is a great choice because of how adaptable it is.Besides having a great amount of storage,it comes with an internal security pocket.It weighs just1.38kg as opposed to other backpacks,which can weigh up to nearly2kg.If you're going to go hiking when you travel,then it is perfect.Mountain Warehouse Tor65LFirst,its brand is one of the most trusted in the industry,so quality is guaranteed.Second,the backpack's adjustable back allows you to change how the bag fits according to your needs.Available inboth blue and green,this is a great choice if you want a bag that you can depend on.Osprey Europe Farpoint70LOsprey is one of the best brands for backpacks.Its frame(框架)suspension,which can be adjusted to different needs,allows you to travel more comfortably.Whether you're visiting Switzerland in a thick,wool coat or the south of France in shorts and a T-shirt,the bag will match your look.This bag does say it is marketed for men,but,of course,it can be unisex.1.What is the selling point of the Amazon Basics?A.Its luxury style.B.Its fashionable design.C.Its huge space for use.D.Its

years old,Angelina Tsuboi discovered her passion for innovation.It all began with a simple game she programmed in her Los Angeles public school's Grade2class.Today,at18,the Grade12 student's initial curiosity has evolved into a deep-seated desire to use technology to decode(解码)real-world problems.In2021,she co-developed Megaphone,one of her first apps,to tackle unanswered post-class questions and poor communication about events and announcements.Her problem-solving ability kept building from there.When she took online CPR classes at the start of the pandemic,she figured it couldn't be just her who was struggling with the steps.So she created an app called CPR Buddy―a winner in the2022Apple Swift Challenge―which guides users through CPR using vibrations(震动)to regulate breath.After winning theaward,Angelina presented her work to Apple CEO Tim Cook,a highlight in her young career,but one she didn't lose her cool over.“There's no point putting people on a pedestal(神坛),”she says.The next year,Angelina built an app called Lilac,designed to assist nonEnglish-speaking single parents with resources for housing,job opportunities and translation support.She was inspired by her own experiences as a child of a single mother who immigrated to the US.When Angelina decided to pursue pilot training at the age of16,she was struck by how difficult it was to find financial support,which encouraged her to create yet another app,Pilot Fast Track,which helps those longing to be pilots find scholarships for flight training.Looking to the future,besides applying to colleges with great labs,Angelina is exploring the field of aerospace cybersecurity and mechatronics―combining computer science,electrical engineering and mechanical engineering.“There's not enough optimism in the world,"she says.“I have also been in situations in my life where I've lost a lot of hope.But in the end,it is a mindset,and there are ways in any situation you're in to make it somewhat better."4.What is Angelina's pursuit?A.To design games for kids.B.To stimulate teen's curiosity.C.To address problems through technology.D.To find innovative approaches to digital challenges.5.What can we learn about Angelina from Paragraph3?A.She couldn't breathe regularly.B.She was inspired by celebrities.C.She replaced CPR with an app.D.She was humble about her success.6.What was the primary goal of developing Pilot Fast Track?A.To direct pilots'career paths.B.To help to-be pilots find funds.C.To pair future pilots with airlines.D.To evaluate pilot training schools.7.What might be the best title?A.Breaking the codeB.Bearing growing painsC.Facing life as it isD.Following role modelsCSome people today might be early risers because of DNA they take after Neanderthals tens of thousands of years ago,suggests new research.When early humans migrated from Africa to Eurasia roughly70,000years ago,some of them mated with Neanderthals,who had already adapted to the colder,darker climates of the north.The ripple(涟漪) effects of that intermating still exist today:Modern humans of non-African ancestry(血统)have between1 and4percent Neanderthal DNA.Some of that DNA relates to sleep more specifically,the internal body clock known as the circadian rhythm.For the new study,researchers compared DNA from today's humans and DNA from Neanderthal fossils(化石).In both groups,they found some of the same genetic variants involved with the circadian rhythm.And they found that modern humans who carry these variants also reported being early risers.For Neanderthals,being“morning people”might not have been the real benefit of carrying these genes.Instead,scientists suggest,Neanderthals’DNA gave them faster,more flexible internal body clocks, which allowed them to adjust more easily to annual changes in daylight.This connection makes sense in the context of human history.When early humans moved north out of Africa,they would have experienced variable daylight hours--shorter days in the winter and longer days in the summer-for the first time.The Neanderthals'circadian rhythm genes likely helped early humans'offspring(后代)adapt to this new environment.Notably,the findings do not prove that Neanderthal genes are responsible for the sleep habits of all early risers.Lots of different factors beyond genetics can contribute,including social and environmental influences.The study also only included DNA from a database called the U.K.Biobank-so the findings may not necessarily apply to all modern humans.Next,the research team hopes to study other genetic databases to see if the same link holds true for people of other ancestries.If the findings do apply more broadly,they may one day be useful for improving sleep in the modern world,where circadian rhythms are disturbed by night shifts and glowing smartphones.8.What does the new research focus on?A.DNA's dramatic changes.B.Genes’influence on early risers.C.Neanderthals’sleeping patterns.D.Ancestors’environmental adaptability.9.What is paragraph2intended to show concerning the new research?A.Historical context.B.Additional proof.C.Sample analysis.D.Studying process.10.What is the real benefit of carrying Neanderthal's DNA for modern humans?A.Getting up earlier.B.Having healthier daily routines.C.Being more flexible in their work.D.Possessing a better circadian rhythm.11.What can be inferred about the findings from the last paragraph?A.They get proof from other studies.B.They are confirmed by early risers.C.They suggest potential applications.D.They reveal factors in sleeping disorders.DI had to say something after reading The Anxious Generation.It is going to sell well,because Jonathan Haidt is telling a scary story about children's development many parents are led to believe. However,the book's repeated suggestion that digital technologies are rewiring our children's brains and causing the epidemic(流行病)of mental illness is unsupported by science.Worse,the rude proposal that social media is to blame might distract(分心)us from effectively responding to the real causes of the current mental-health crisis in young people.Researchers have searched for the effects suggested by Haidt.Our efforts have produced a mix of no, small and mixed associations.Most data are correlative.When associations over time are found,they suggest not that social-media use predicts or causes depression,but that young people who already have mental-health problems use such platforms more often or in different ways from their healthy peers.We are not alone here.Several analyses and systematic reviews centralize on the same message.An analysis done in72countries shows no consistent or measurable associations between well-being and social media globally.Moreover,studies from some authorities finds no evidence of intense changes associated with digital-technology use.As a psychologist studying children's and adolescents’mental health,I appreciate parents’frustration(沮丧)and desire for simple answers.As a parent of adolescents,I would also like to identify a simple source for the pain this generation is reporting.There are,however,no simple answers.The beginning and development of mental disorders are driven by a complex set of genetic and environmental factors.More young people are talking openly about their mental-health struggles than ever before.But insufficient services are available to address their needs.In the United States,there is,on average,one school psychologist for every1,119students.We have a generation in crisis and in desperate need of the best of what science and evidence-based solutions can offer.Unfortunately,our time is being spent telling stories that are unsupported by research and that do little to support young people who need,and deserve, more.12.What is presented in The Anxious Generation?A.Scary stories affect children's brains.B.Parents are responsible for children's health.C.Teen's mental illness results from screen time.D.The epidemic of mental illness is unavoidable.13.What does“the same message”underlined in paragraph3refer to?A.Many countries do research in mental health.B.Well-being and social media are closely related.C.The young are trapped in the mental-health crisis,D.Social media don't necessarily cause mental illness.14.What is implied in the last paragraph?A.Effective actions need to be taken.B.Positive stories should be shared.C.Financial support needs to be provided.D.Broader research should be done.15.What is the author's purpose in writing the text?A.To suggest ways to help those in need.B.To encourage parents to brave the crisis.C.To recommend a newly-published book.D.To give a voice to children's mental issues.第二节(共5小题;每小题2.5分,满分12.5分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。
