teaching college for many years.I've long grown used to the torn jeans,slippers,shorts inthe dead of the Maine winter,and ball caps worn backward.Still,when one of my students showed up inpajama(E衣）bottoms,I couldn't help asking,"Did you just roll out of bed?"He responded:"Fiveminutes ago."I'm familiar with the school of thought that says that how students dress is unrelated,so long asthey're learning.I put it in the same category as"Grammar and spelling don't matter,so long as they'reexpressing themselves".I wonder about the wisdom of blurring(模糊）the line between bed and desk.I smile when I think back on the occassions that my parents associated with needing to lookrespectable.Once,when I was 14 and my brother was 12,my father announced that he was taking us intoManhattan(just a subway ride away)to see the play.My brother and I were excited at the hope,but wereshortly discouraged when my father directed us to put on our best clothes,including jackets and ties."Butwhy?"I begged,not wanting to change out of my comfortable jeans,T-shirt,and sneakers."Because,"hesaid,“we're going to New York."I can still see the stars in his eyes as he said these words.So yes,I do want my students to be comfortable.But I also want to pay my respects to those studentswho believe that appearances count.I think of the woman-a somewhat older student-I had in class a few years back.She was someoneto whom science did not come easily:She worked determinedly for respectable grades on every homework.But I was struck by how tastefully she dressed,day after day.Once,I said,"You always looked so nice."Immediately,she answered,"I've waited 12 years toreturn to school,and I dress up to remind myself to be serious about it."And,I might add,she seemed perfectly comfortable to me.24.What phenomenon is described in the first paragraph?A.Students care little about class attendance.B.Students show their personality through dress.C.Students tend to ignore their personal appearance.D.Students make it a habit to be late for school.25.What's the writer's attitude towards the school of thought?A.Ambiguous.B.Supportive.C.Doubtful.D.Disapproving.26.What can we learn about the writer's parents from Paragraph 3?A.They considered personal appearance important.B.They looked after their children with great care.C.They often paid a visit to New York.D.They preferred dressing formally on a subway.27.Why did the older student dress tastefully every day?A.To feel comfortable at class with others.B.To show her serious attitude towards learning.C.To impress others with respectable clothes.D.To hide her embarrassment at poor homework.CAmerican Grace Brown is keeping busy during her first year of high school.She studies all therequired subjects,such as English,history and mathematics,as well as taking classes in Latin.She alsosings in a music group and plays the piano.The school day lasts from about eight o'clock in themorning to three in the afternoon.But because of her many activities,she has no time for a class inphysical education,or PE.So Grace is getting school credit for virtual PE.She wears a fitness tracker called Fitbit that the high school provided.She wears the Fitbit on her arm while doing exercises lasting 30 minutes or longer three times a week.Her computer has a software program that records her activity which she can present for credit.A PE teacher may not be guiding the Fitbit-wearing students in person.But teachers do lead students'work by setting goals such as fat burn,using the technology as their eyes and ears."We certainly exercisemore in online PE,"Brown said."There's a lot of standing around in regular PE.Online,I do much harderworkouts."Grace's mother,Rhonda Brown,remembers how hard PE class and softball games were for herbecause of blindness in one eye.She would like to see Fairfax County give students permission to avoid PEif they play school sports.＂We're so stuck in the traditional classroom setting.These kids are burning 2,000 calories(卡路里）during a practice and more at every game,"Rhonda said."I wish the schools would catch up with the times."It is not clear how many schools are supporting the trend.Technology and the collection of anystudent data always raise the problem of student privacy concerns."There is a difference between physicalactivity and physical education,"said Chris Hersl.Physical activity is great for the body.We want everybody to move,but physical education is a class where students are taught how to move their body and the social context in which to do that."28.Why does Grace take virtual PE?A.She is busy with school activities.B.She prefers something new.C.She has interest in wearable technology.D.She loves being tracked while doing

couldn't burn 2,000 calories per game.D.She was blind in one of her eyes.31.What does Chris stress in his words?A.Wearable technology threatens students'privacy.B.Physical activities need students'teamwork.C.PE is also about students'social connection.D.Online PE collects a lot of students' data.DWhen you think of the Himalayas,you may picture tall,rocky,snow-covered peaks.But that's nottrue.The subnival(亚冰雪的）region is the zone between the treeline and the snowline.It is 5 to 15 times as large as the areas of glaciers(冰川）and permanent snow,which means studying it is vital to understanding the Himalayas as a whole.The treeline is the edge of an ecosystem where trees are able to grow,and beyond the treeline environmental conditions become too tough to allow tree growth.Meanwhile,snowlines are theboundaries on mountains that separate areas with permanent snow(where snow is present for the majority of the year)from areas with seasonal or no snow.Researchers used satellite data from 1993 to 2018 to measure plant cover between 4,150 meters and 6,000 meters above sea level.The scientists discovered that the greatest increase in plant cover was between an altitude of 5,000 meters and 5,500 meters.Subnival plants mostly include small shrubs and grasses.Even areas once completely occupied by glaciers now hold rocks covered with mosses(苔藓），lichen（地衣），and sometimes even flowers.In addition,the snowline seems to be retreating,while the treeline is expanding.This shows that the region is becoming warmer,causing more melting of snow and allowingvegetation to move up in height.In the past 40 years,25%of all Himalayan ice has been lost due to global warming.Himalayanglaciers are reducing by about 0.5 meters each year.The rate of glacier melting has doubled in this decade.The melting of glaciers increases water in the region,making it wetter.Receding snow also forces the snowline to move up,providing a greater amount of area for the warm and moist conditions,which areperfect for vegetation growth.As of now,we do not know whether vegetation will accelerate or slow down the rate of glaciermelting.32.How does the writer develop the third paragraph?A.By making explanations.B.By giving some examples.C.By analyzing cause and effect.D.By listing specific data.33.What does the underlined word"retreating"mean in Paragraph 5?A.Disappearing.B.Lengthening.C. Withdrawing.D.Widening.34.What is the direct effect of global warming on the Himalayas?A.The snowline moves up.B.Glaciers are melting faster.C.The subnival area is wetter.D.Plants grow much better.35.What is the best title for the text?A.The Climate of Himalayas Is Changing.B.Icebergs in the Himalayas Disappear.C.Plants Are Diverse in the Himalayas.D.Plant Life Spreads in the Himalayas.第二节（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填人空白处的最佳选项，选项中有两项为多余选项。
