teacher at Blackwell Public School and last yearshe bought a plain(朴素的)white dress,which she set up a station in her classroom for her students to decorate,encouraging them to go and draw on the dress whenever they had free time.Haley set up a station at a table with the dress and some color1 ed markers so that her students could draw on it,having first seen the idea on Pinterest.After the kids had finished the design,she then surprised them all by wearing the dress to class,sharing pictures of herself in it on Facebook in a post that has since been shared over 200,000 times.For teachers looking to do something similar for their own students,Haley said that she bought the dress off Amazon for less than$20 about six months ago and pre-washed the dress before she started the project.She used markers from Walmart.But she said these things can be bought in other places.She said,“To do the project,I set up a station at a table with the dress and markers.It takes anywhere from two weeks to a month to complete as we just work on it here and there when time allows.Youd better give the students enough time so they dont have to hurry.”“Teachers have been sharing their dresses,T-shirts,etc.with me that theyve been creating since the 1950s with the same idea.It is amazing,and I love the fact that you are sharing them with me!Thank you all so much for your kindness and support,”she wrote on Facebook.Asked why she came up with the idea,Haley told Scary Mommy.“We dont have art in our school,so,I always try to do little creative projects when possible.”4.What did Haley use the plain white dress to do?A.To teach her students painting.B.To prepare for her presentation.C.To ask her students to draw on it.D.To help her students with their homework.5.What do we know about the finished dress?A.It took Haley by surprise.B.It is kept by Haley at home.C.It is the product of a new idea.D.It has enjoyed popularity online.6.What should a teacher do if he or she wants to follow Haleys example?A.Buy the same dress online.B.Give the kids enough time.C.Buy the same markers in Walmart.D.Leave the finished work untouched.7.Why did Haley carry out the project?A.To teach art to her students.B.To show her idea on Pinterest.C.To share it with other teachers.D.To exciteher students creativity.C Summer is quickly passing bybut not without the ultimate meteor（流星）shower event!The2021 Perseids Meteor Shower,which is considered to be the best meteor shower of the year,is expected to start lighting up skies on this Wednesday,according to NASA.Known for fireballs,the Perseids typically light up skies on warm summer nights,leaving“long wake（尾迹）of light and color1 behind them.”Under ideal conditions,sky watchers may see approximately 50-100 meteors per hour with each meteor traveling at 37 miles per second.Because the meteors appear in all parts of the sky,it will be pretty easy to witness the celestial（天上的）event from anywhere in the world.To get the best show,it is advised to view the Perseids from the Northern Hemisphere（半球）during the pre-dawn hours,ideally between 2 a.m.and dawn.In some cases,sky gazers may be able to seemeteors during this shower as early as 9 or 10 p.m.“If its not cloudy,pick an observing spot away from bright lights,lie on your back,and look up!You dont need any special equipment to view the Perseidsjust your eyes,”NASA wrote on their site,adding that telescopes or binoculars are not recommended due to their small fields of view.Remember to let your eyes become adjusted to the dark.Try to stay off of your phone too,as looking at devices with bright screens will negatively affect your night vision and thus reduce the number of meteors you see!For those who may be unable to view the Perseids in person,a live broadcast will be streaming from NASAs Marshall Space Flight Center,starting around 8 p.m.on Aug.11 and continuing through sunrise on Aug.12.8.What can we learn about the Perseids Meteor Shower?A.It will be the best meteor shower in history.B.The ultimate shower only happens on this Wednesday.C.We can observe 50-100 meteors per hour in any place.D.The Meteors usually have long and bright trails behind them.9.Which of the following may be the best time to view the shower?A.At 4 a.m.on the Northern Hemisphere.B.At 2 p.m.on the Northern Hemisphere.C.At sunrise on the Southern Hemisphere.D.At dawn on the Southern Hemisphere.10.What can be inferred about the observation of Meteors?A.If you use a telescope,you will see more meteors.B.You can use smartphones to record the grand scene.C.The brighter the moon is,the more meteors you can see.D.Bright lights will reduce the visibility of meteors.11.If you are not available to watch the Perseids personally,you can _.A.browse the unofficial website of NASA B.watch a video recorded by a flight center C.stream a live show on Aug.11 night D.use special devices to connect with the shower D We are in lack of enough sleep,according to Arianna Huffington,the co-founder and editor-in-chief of The Huffington Post.And thishas great consequences on our health,our job performance,our relationships and our happiness.What is needed,she ly declares,is nothing short of a sleep revolution.Only by renewing our relationship with sleep can we take back control of our lives.In her bestseller Thrive,Arianna wrote about our need to redefine success through wellbeing,wisdom,wonder,and giving.Her discussion of the importance of sleep as a gateway to this more fulfilling way of living struck such a powerful chord(弦)that she realized the mystery and transformative power of sleep called for a fuller investigation(调查).The result is a scientifically sweeping and personal exploration of sleep from all angles,from the history of sleep,to the role of dreams in our lives,to the consequences of sleep deprivation(剥夺),and the new golden age of sleep science that is showing the vital role sleep plays in our every waking moment and every aspect of our health from weight gain,diabetes,and heart disease to cancer and Alzheimers.In The Sleep Revolution,Arianna shows how our cultural removal of sleep as time wasted damages our health and our decision-making and our work lives and shortens our personal lives.She explores all the latest science on what exactly is going on while we sleep and dream.She decides the dangerous sleeping pill industry,and all the ways of our addiction to technology disturb our sleep.She also offers a range of recommendations and tips from leading scientists on how we can get better and more restorative sleep.In todays fast-paced,always-connected and sleep-deprived world,our need for a good nights sleep is more important than ever.The Sleep Revolution both sounds the alarm on our worldwide sleep crisis and provides a detailed road map to the great sleep awakening that can help transform our lives,our communities,and our world.12.What is the first paragraph mainly about?A.The importance of sleep.B.The necessity of improving sleep.C.The way to improve our sleep.D.The effect of sleep on health.13.What can be inferred about Ariannas attitude to success?A.She thinks good sleep is more important.B.She doesnt think much of becoming successful.C.She thinks it wrong to sacrifice health to success.D.She is concerned about the nature of success.14.What can be said about Ariannas investigation?A.It is really of great value.B.It is scientific and historical.C.It costs Ariannas sleep in practice.D.It covers all necessary aspects scientifically,15.What influence does TheSleep Revolution have on society?A.It helps to slow down the pace of modern life.B.It warns people against taking sleeping pills.C.It warns the harm of inadequate sleep of people.D.It helps to stress the value of sleep to success.第二节（共 5 小题；每小题 2 分，满分 10 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 When germs,such as bacteria or viruses,invade the body,they attack and multiply.36 The immune system uses several tools to fight infection（感染）.Blood contains red blood cells,for carrying oxygen to tissues and organs,and white or immune cells,for fighting infection.These white cells consist primarily of macrophages（巨噬细胞）,B cells and T cells.Macrophages swallow up and digest germs,plus dead and dying cells.They leave behind parts of the invading germs called antigens（抗原）.37 B cells are defensive white blood cells which produce antibodies.T cells are also defensive white blood cells.They attack cells in the body that have already been infected.The first time the body comes across a germ,it can take several days to make and use all the germ fighting tools needed to get over the infection.After the infection,the immune system remembers what is learned about how to protect the body against that disease.38 They help develop immunity by imitating an infection.This type of infection,however,almost never causes illness,but it does cause the immune system to produce T cells and antibodies.Sometimes,after getting a vaccine（疫苗）,the imitation infection can cause minor symptoms.For instance,a fever.39 Once the imitation infection goes away,the body is left with a supply of defensive cells that will remember how to find that disease in the future.40 Therefore,itis possible that a person infected with the disease just before or just after vaccination could develop symptoms and get a disease,because the vaccine has not had enough time to provide protection.A.Vaccines basically work the same way.B.This invasion,called an infection,is what causes illness.C.Vaccines prevent diseases that can be dangerous,or even deadly D.Scientists take many different approaches to developing vaccines.E.The body identifies them as dangers and excites antibodies to attack them.F.Such minor symptoms are normal and should be expected as the body builds immunity.G.However,it typically takes a few weeks for the body to produce those defensive cells after vaccination.第二部分 语言运用（共两节，满分 45 分）第一节（共 20 小题；每小题 1.5 分，满分 30 分）阅读下面短文，从每题所给的 A、B、C、D 四个选项中选出可以填入空白处的最佳选项 A little girl,named Starry,was playing outside her grandmothers apartment
