was five years old when his mother,Kelly,was driving along the country road with him.He was asleep on the front seat of their truck,with his feet resting on her lap.As his mom drove carefully down the winding country road,she turned onto a narrow bridge.The truck hit a rock and slid off the road.She attempted to bring it back up onto the road by pressing hard on the gas pedal(踏板)and turning the steering wheel to the left.But Rockys foot got caught between her leg and the steering wheel and she lost control of the truck.The truck fell into a 20-foot valley.When it hit the bottom,Rocky woke up.“What happened,Mom?”he asked.“Our wheels are pointing toward the sky.”Kelly was seriously wounded and blinded by blood.“Ill get you out,Mom,”announced Rocky,who had surprisingly escaped injury.He climbed out from under Kelly,slid through the open window and tried to yank his mother out.But she didnt move.“Just let me sleep,”begged Kelly,who was out of consciousness.Rocky insisted,“Mom,you cant go to sleep.”Rocky managed to push Kelly out of the truck and told her hed climb up to the road and stop a car to get help.Fearing that no one would be able to see her little boy in the dark,Kelly refused to let him go alone.Instead,they slowly moved up to the road.The pain was so great that Kelly wanted to give up,but Rocky wouldnt let her.Rocky kept repeating the inspirational phrase,“I know you can.I know you can.”When they finally reached the road,Rocky broke into tears seeing his mothers torn face clearly for the first time.Waving his arms and shouting“Please stop!”,the boy stopped a truck.His mother was sent to hospital.It took eight hours to rebuild Kellys face.She looks quite different todayshe has a few scars but has recovered from her injuries.Rockys heroics were big news.Everyone was surprised at this little boys power.“Its not like I wanted it to happen,”the boy explained.“I just did what anyone would have done.”“If it werent for Rocky,Id have died,”said his mother.24.What do we know about Rocky and Kelly?A.They were lost on a country road.B.They had a serious truck accident.C.They had limited time to restart the truck.D.They knew little of what happened to them.25.What had happened when Rocky woke up?A.The truck had turned over.B.His mother had passed out.C.The truck broke down halfway.D.His mother fell out of the truck.26.What does the underlined word“yank”in paragraph 3 most probably mean?A.Pull.B.Drive.C.Follow.D.Catch.27.Which of the following words can best describe Rocky?A.Enthusiastic and kind.B.Cooperative and generous.C.Courageous and calm.D.Adventurous and energetic.CSleep is widely recognized as one of lifes essential processes.But did you know that sleepless nights can also lead to selfish behavior?Insufficient sleep affects how likely a person is to help someone,according to new research published in the journal PLOS Biology.Researchers from the University of California,Berkeley,conducted three studies looking at this“selfish”effect,analyzing changes in neural(神经的)activity and behavior benefiting others,and found it was very common even after a small loss of sleep.Study leads Ben Simon and Matthew Walker said that this finding was most surprising.“When people lose one hour of sleep,theres a clear hit on our natural human kindness and our motivation to help other people in need,”said Ben Simon.In the first study,by looking at a database of 3 million charitable donations between 2001 and 2016,Ben Simon,Walker and their colleagues saw a 10%drop in donations following Daylight Saving Time(夏令时).This drop was not seen in states that dont follow the one-hour transition forward.In the second study,the researchers looked at the brain activity of 24 people after eight hours of sleep and after a night of no sleep.The prosocial(亲社会的)neural networkthe areas of the brain associated with theory of mindwas less active after sleep loss,this study found.In the third study,which measured the sleep of more than 100 people across three to four nights,researchers unexpectedly found that quality of sleep was more important than the quantity of sleep when it came to measuring selfishness.Sleep quantity and quality both typically influence emotional and social behavior,Ben Simon said.Ben Simon and Walker hope their research will allow people to regain a full night of sleep without embarrassment.“Sleep loss changes how we are as social,emotional beings,which you could argue is the very essence of human interaction and what it means to live a fulfilling human existence,”Walker said.28.How does sleep loss influence people according to the researchers?A.It will cause damage to their health.B.It will lead them to make wrong choices.C.It will reduce their communication efficiency.D.It will discourage them from doing good deeds.29.What can we know about the first study?A.It focused on sleep-related selfless behavior.B.It saw a 10%drop in donations all year round.C.It found the brain less active after sleep loss.D.It was carried out with a charitable organization.30.It can be inferred from paragraph 3 that the series of studies was.A.fruitlessB.immoralC.systematicD.recreational31.What can be the most suitable title for the text?A.Three important studies B.The less sleep,the more selfish?C.An interesting topic on peoples sleeping D.Sleep quality or quantity,which matters more?DScientists have described a new disease called plasticosis,which is directly caused by plastic waste in the environment.While the disease has so far only been identified in the digestive tracts(消化道)of seabirds,the scale of the problem suggests it could be widespread in other species and different parts of the body.Plastic is one of the most popular materials in our world,so its not surprising its also among the most common pollutants.Microscale plastic fragments have been detected in the bodies of fish,birds,whales,seals,farm animals and humans,and the extent of the biological damage they cause is still being investigated.For the new study,scientists from Londons Natural History Museum have now examined the ill effects on the health of a seabird species known as flesh-footed shearwaters,which previous studies have found to be among the most plastic-polluted birds in the world.Plasticosis got its name due to its similarity to other fibrotic diseases caused by inorganic materials,like silicosis and asbestosis.Tiny parts of plastic stay in the birds digestive tracts,causing chronic inflammation(慢性炎症)and scarring that leads to a lot of other problems.The team found that exposure to microplastics inflames and scars the proventriculus(前胃),the first chamber of their stomach,until it eventually starts to break down.That can affect the glands that offer digestive compounds,which can affect their vitamin absorption and make them more vulnerable(脆弱的)to infection and parasites.In extreme cases,chicks can starve to death because their stomachs become full of indigestible plastic.For those that survive,plasticosis seems to affect their growth.Larger amounts of plastic were associated with smaller overall weight and shorter wings.So far,plasticosis has only been documented in the digestive systems of these flesh-footed shearwaters,but given how common the pollutant is,the team says its likely that the disease affects other species as well,and could cause similar scarring in other parts of the body.Investigating this could be an important step for future work.32.What can we learn about plasticosis from the first paragraph?A.It only affects some seabirds.B.It is caused by ocean pollution.C.It is a recently discovered disease.D.It is limited to the digestive system.33.Why are flesh-footed shearwaters chosen to be the study object?A.They are probably the most endangered species of seabirds.B.They are probably the most seriously plastic-polluted birds.C.They are probably the most vulnerable to plastic pollutants.D.They are probably the most valuable for ocean exploitation.34.What does the underlined word“it”in paragraph 3 refer to?A.The proventriculus.B.Vitamin absorption.C.Indigestible plastic.D.Chronic inflammation.35.Whats the most suitable title for the text?A.Plastic waste affects seabirds and their habitats B.The unseen impact of ocean pollution on wildlifeC.New disease in birds highlights dangers of microplasticsD.A comprehensive study on microplastics in the marine ecosystem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。选项中有两项为多余选项。Do Kids Need Homework?36 School is a big part of life,not just for kids but for their families and for educators,too.Everyone has an opinion about whats best for students.And they dont always agree.Pradyun Senthilkumar(9,Los Angeles,California)Kids need homework.When they learn something new in school,reviewing it at home helps them remember it.37 Thats because theres a lot we need to learn.In math,were learning addition,subtraction,multiplication,and division.In language arts,were learning spelling,reading,and writing.And were also learning how to speak.Olivia Lin(9,Minnetonka,Minnesota)In my opinion,giving students homework is a bad idea.Kids need time after school for experiences that build a healthy mind and body.Homework is not supposed to stress kids out.Its meant to help them grow.But when homework piles up,students get stressed.38 Isla Dhaliwal-Grizzell(8,Spokane,Washington)Kids need homework.39 Middle and high school students are ready for added responsibility.So they can do much more homework.At my school,elementary students get homework,but not too much.My teacher might assign us spelling words to learn at home,and each week well be given a test.But other assignments can require families to work with kids at home,if they need extra help.Nathaniel Kim(11,South Pasadena,California)Many people believe that homework is essential.They say it can teach kids how to complete tasks on a deadline.40 But it takes time away from learning material that wasnt covered in class.And theres no guarantee that time spent on homework will be more effective than time spent in the classroom,if students are paying attention and taking notes.A.But the amount should vary by age.B.Others say homework adds to students stress.C.Theyre learning for six hours a day at school.D.At my school,teachers give math and language arts homework.E.We knew this question would spark lively
