suitcases appearance.C.The suitcases weight.D.The users picture.B There are many challenges such as kayaking（划独木舟）the Colorado River Rapids,climbing to the summit（顶峰）of Qomolangma,mountain biking Colorados 100-mile Leadville Trail and skydiving solo.Adventurers take on these challenges all the time.One thing that makes an American named Erik Weihenmayer stand out is that he has done them all without the sense of sight.He is the first blind person to have climbed the tallest peak in every continent.When he was 4 or 5 years old,he was diagnosed with an extremely rare disease called retinoschisis（视网膜劈裂症）and when he finally went blind,he felt it was an unbelievable relief as if the worst thing had happened,so theres nothing else to lose.He began rock climbing with the help of a recreational group taking blind kids rock climbing and fell in love with it immediately.He felt it was just for him.It was sort of the full package of adventure,all the things he wouldnt have as a blind perso凡He has learned to do the things,which sighted people learn to do with their eyes,with his hands.He stated“When people say they climb for the view,I think theyre misunderstanding why we do the things we do.Honestly,the summit is not the destination.The movement is for me the most exciting part.”As a blind climber,its really hard,but he has to accept that suffering.Blindness is just a thing that happened to him.He thinks he likes all challenges and that people have got to use them as a drive to push them in new directions.Its the idea of turning bad things into good things,and its something all could use.24.What is special about Erik Weihenmayer?A.He skydived with other adventures.B.He swam across the Colorado River Rapids.C.He completed many adventures as a blind man,D.He kayaked Colorados 100-mile Leadville Trail.25.How did Erik Weihenmayer feel when he eventually lost his sight?A.Relaxed.B.Shocked,C.Annoyed.D.Disappointed.26.What does Erik Weihenmayer value most in climbing Qomolangma?A.The recognition of others.，高二英语第4页（共10页）22-11-182BB.The feeling of standing on the summit.C.The destination of climbing.D.The process of climbing.27.What is the purpose of the text?A.To talk about some adventuresB.To introduce an adventurer without sight.C.To gain other blind climbers support.D.To attract other blind persons.c The continuous increase in the number of COVID-19 cases worldwide has had a deep and broad effect on how we live and interact with one another,resulting in many changes that are likely to be long-lasting.For example,to reduce contact during COVID-19,shaking hands,a standard style of greeting used by officials and businessmen has been replaced.In the US,the country hardesthit by the outbreak,with over 36 million confirmed cases of COVID-19 and more than 610,000 deaths,the top health official said such social gatherings should end,even when COVID-19 is over.Anthony Fauci,director of the US National Institute of Allergy and Infectious Diseases,told The Wall Street ournal，“I dont think we should ever shake hands ever again,to be honest with you.”Neel Gandhi,a professor at Emory University in Atlanta,Georgia,told ESPN,a US sports broadcaster，“When we talk about transmission,the hands are the place that I focus on the most.”If such advice from health experts is followed,it will produce a big shift in human behavior.However,some people are finding alternative ways to greet one another at a time when direct contact is disapproved of.In South Korea,bowing deeply has become popular.In Australia,officials have suggested that people pat each other on the back instead of shaking hands.Handshakes are just one form of contact that has largely ended during COVID-19,along with hugging and high-fives.As many people worldwide rebuild their social lives,experts are predicting that some degree of social contact will disappear for good.Chen Xuefeng,deputy director of the Institute of Psychology at the Chinese Academy of Sciences,said，“In the post-COVID-19 era,people are likely to behave more坠旦旦xfor a while.They will pay more attention to themselves,such as caring for their health,spending more time alone,moving offline activities online,socializing less and saving more.”Chen added，“This new way of life means that some industries where old habits are deep甸rooted will face challenges in upgrading.”28.What does Anthony Fauci suggest doing in the face of COVID-19?A.A voiding handshakes.B.Ending social gatherings.C.Moving offline activities online.D.Using a standard style of greeting.高二英语第5页（共10页）22一11-1828 29.How does the author show the big change in human behavior in paragraph 3?A.By example.B.By data.C.By experiment.D.By imagination.30.What does the word“discreetly”in the last paragraph probably mean?A.Confidently.B.Carefully.C.Capably.D.Comically.31.What is the text mainly about?A.Old unnecessary habits worldwide.B.Traditional forms of communication.C.The disasters in the post-COVlD-19 era.D.The social contact changes caused by COVID-19.D An alarming scientific review has found human activity is driving insects to extmctton.When the bottom of the food chain is endangered,so is everything up the chain,including people.Insect reductions threaten birds,fish,reptiles and amphibians（两栖动物）that eat insects,as well as many plants that require them for pollination（授粉）.Insects are also important to soil health,nutrient recycling and ecosystem functioning.Habitat loss from intensive agriculture and urbanization is the main cause of the reductions,according to the review“Worldwide reduction of insects:A review of its drivers”.Agricultural pesticide（杀虫剂）and fertilizer use,pathogens,invasive species and climate change are also major reasons.A World Wildlife Fund study concluded that weve wiped out 60 percent of mammals,fish,birds and reptiles since 1970.Another study found people have destroyed 83 percent of wild mammals and half of all plants since the dawn of civilization.As frightening as that,the rate of insect extinction is eight times that of mammals,birds and reptiles.If these trends continue,most insects could be gone within a century,which will severely affect all life.Some solutions can be carried out quickly and relatively easily,such as banning the worst pesticides,carrying out many available and emerging solutions to pollution and global warmi吨，and examining better ways to grow,produce and distribute food.Sanchez-Ba yo argues that changes in agricultural methods are extremely important,noting organic farms and farms that used limited pesticide amounts in the past had more insects.Research also shows organic farms maintain healthier soils,use less energy,send out fewer greenhouse gas emissions and produce higher yields than conventional farms,especially during droughts.Many people are frightened at the thought of bites and stings by insects.But whatever you think of them,theres no doubt that theyre essential to all life.If insects die out,we wont survive.From banning destructive pesticides to reforming agricultural methods toplanting insect-and pollinator-friendly gardens in urban areas,theres much we can and mustdo to help the creatures survive and develop.32.What may insect extinction result in?A.Improving soil health.B.Reducing human activities.I高二英语第6页（共10页）)22-ll-182B.C.Increasing the varieties of plants and animals.D.Threatening all up the food chain depending on them.33.Which of the following creatures disappear most quickly
