Her parents, both teachers，had small salaries and were quite poor, especially after her mother stopped teaching to raise five children and take care of her poor health. Marie's mother suffered from tuberculosis (肺结核) and died of it when Marie was ten.When Marie was small, she showed great interest in science.She loved to study and hoped to become a scientist when she grew up. Her parents encouraged her interest in science.Excellent as she was in her studies，she couldn't go on with the advanced education she needed because Poland was then ruled by Russia and women were not permitted to go to college.In order to continue her education, she smoothed away many difficulties and entered Paris University，where she lived a simple life and studied hard, so she graduated with the highest grades in her class.After graduation she was engaged in scientific research in Paris University. There she met Pierre Curie, whom she married.Pierre joined her in her research into an unknown phenomenon “radiation”，which a certain scientist had declared that uranium gave off.The Curie spent several years trying their best to find the element that produced radiation. Finally they succeeded in 1902.Marie Curie won two Nobel Prizes, one for physics in 1906, together with her husband and another scientist; the other for chemistry herself in 1911.Madame Curie was a scientist of great achievement，and the first woman ever to be honored in the Nobel Prize history.【语篇解读】本文语篇类型是说明文，文章向我们描述了玛丽居里传奇的一生，她热爱科学研究，并且深具真正的品格和精神。

Melody,it looked different because of the classmate who graduated alongside her — her grandmother,75-year-old Pat Ormond.They both went to the University of Tennessee at Chattanooga(UTC) and graduated together.Pat took her first college class 42 years ago.After one semester,she dropped out to move to Chattanooga,where she spent the next several decades working as an accountant and raising a family.While she did take an occasional class at UTC,she said her family continued to encourage her to go back to finish her degree,especially after she retired.She agreed when her granddaughter decided to move to study psychology at UTC after a year at Berea College.They both entered UTC with enough college credits to make graduating together a possibility.Pat and Melody graduated on November 20 as part of UTC’s 2020 class.The achievement has also made Pat somewhat of a celebrity.“We are so proud to have graduates like Melody and her grandmother,Pat Ormond,in the UTC class of 2020,” said Steven,UTC Chancellor,“Together,they personify the determination,commitment and love for lifelong learning we encourage in every UTC graduate.”Pat hopes that she can be an example to other non-traditional college students who want to get their degrees.“Learning never stops,” Pat said.“That’s something that my father taught me when I was young.No matter what you do,learning never stops.” Pat isn’t planning to stop anytime soon.She’s already working on another degree—a bachelor’s degree in history.Meanwhile,her granddaughter,who is hunting jobs,is interested in getting a master’s

year alone,healthcare professionals from all over the world have been putting themselves in a harmful way to treat COVID-19 patients.In times like this it is more important than ever that everyone has access to a doctor.But,according to statistics from the WHO,China has 19.79 medical doctors per 10,000 people,the US has 26.12,and the UK has 27.86.However,the rise of telemedicine allows doctors to make better use of their time and provides better healthcare access,especially for those in rural areas.Telemedicine is the remote delivery of healthcare services,including online consultations and diagnoses,and remote patient monitoring.According to the World Economic Forum,“Nearly every other industry adopted widespread use of conference calls,and more recently,used video chats in order to cooperate remotely,while healthcare providers and patients both hesitated to adopt these tools to deliver healthcare.” However,COVID-19 could push them to adopt the new approach.Having one of the best healthcare systems in the world,Switzerland already offers virtual video appointments for private patients,and with cloud computing,this care can go even further.With patient data being stored in the cloud,medical records can be easily shared and updated by all healthcare providers when required.With the addition of powerful cloud networks,wearable technology,such as bracelets,can monitor a patient’s key signs from their homes,removing the need for hospital care.Seema,administrator of Medicare and Medicaid Center,told the Wall Street Journal,“The arrival of telehealth has been just completely speeded,and it’s taken this crisis to push us to a new frontier.” Indeed,telemedicine will have a huge effect on medical care,allowing for more personalized treatment of patients after COVID-19 has relieved.8.What services does telemedicine not offer to online patients?A.Online operations.B.Online consultations.C.Remote patient monitoring.D.Virtual video appointments.9.What is Seema’s attitude towards the future of telemedicine?A.Worried.B.Doubtful.C.Optimistic.D.Cautious.10.What can we infer from the text?A.The number of medical doctors per 10,000 is relatively small in China.B.The US has the largest number of medical doctors in the world.C.Only Switzerland has the most developed medical system in the world.D.Conference calls and video chats have been used widely in telemedicine.11.Which of the following can be the best title for this text?A.The Side Effects of COVID-19B.Online Medical CareC.The Shortage of Medical CareD.The Advanced Medical TechnologyD(2021·山东济南模拟)When Harrison School District 2 turned to e-learning last spring,they made sure to provide each student with a laptop and the tools needed to succeed at home.But one remaining need in many families was Internet access.Christine O’Brien,spokesperson for District 2 said,“When you had many people learning and working from home,sometimes there were Internet glitches.We wanted to avoid that and make sure students in our district could have equal chances to learn and that our families could learn from home as well.”O’Brien said that this year they made sure to survey each of their students to see who exactly needed the Internet.“This year we were really specific about asking whether families had Internet service at home without a phone,” she said.They discovered that about a thousand families needed some sort of Internet connection.And that’s where Altia came into play.A local software company heard there was an Internet shortage for students and it stepped in to see how they could help.Teaming up with local foundations(基金会),they were able to provide a monthly Internet service that allows many people to have Internet access at the same time.Mike Juran,CEO of Altia said,“At Altia we talked to Randy Rocha at District 2 and I just put out an email to friends and people that I knew and that made its way back to Pikes Peak Community Foundation and Norwood Foundation and people spread that around.Within weeks we were able to get something done.”“The community came together and helped us piece this part.We worked so hard as a school district to get those devices into the hands of students but this was a piece that we weren’t ready to do.We hadn’t budgeted(预算) for it,so the community’s coming together to help our families in this way was really truly amazing,” said O’Brien.12.What does the underlined word “glitches” in paragraph 2 mean?ers.B.Services.C.Problems.D.Repairmen.13.What did Harrison School District 2 do according to O’Brien?A.They kept track of students’ situations.B.They sold laptops to students cheaply.C.They kept holding new learning programs.D.They encouraged students to treat each other equally.14.How did Altia help to make e-learning easier?A.By visiting the families every month.B.By sending emails to students every week.C.By setting up a local foundation to raise money.D.By offering Internet service to students in

Unit 2Morals and Virtues 单元测试第一部分阅读理解（共两节）第一节AWhen Susan Saunders was 36, her mother was diagnosed(诊断) with severe dementia(痴呆). “I had a full-time job as a TV producer and I became a carer as well.” As a teenager, she watched her mum care for her own mother, who had the same condition. “I decided to increase my and my families’ chances of ageing well.”Annabel Streets’ story is similar. As a student, she watched her mother care for her grandmother, who lived with dementia for nearly 30 years. She said, “When I developed a chronic autoimmune disease, I knew things had to change.”Together, Saunders and Streets started researching the latest science on how to have a healthier, happier old age and blogged about their findings for five years. Their Age Well Project has now been published as a book, and Streets and Saunders, both in their 50s, say they have never been in better health. What did they learn?Walk fasterWalking is good, but pace matters. Fast walking has been linked to better memory, better health and a longer life. Increase your pace until you are slightly out of breath or sweaty.Read booksFrequent reading has been linked to longer, healthier life. A Yale study of 3,600 over-50s found that reading increased longevity by almost two years. While those who read for more than 3.5 hours a week lived longest. Work longerWhile many people dream of retirement, a new study found that people who worked longer lived longer. This is because working usually involves social interaction, movement and a sense of purpose. But working long hours year after year is not the answer either. From mid-life on, the sweet spot for health and longevity is working at a less intense pace and for fewer hours.1. Which of the followings is right?A. Susan Saunders was diagnosed with severe dementia at 36.B. Saunders and Streets try to increase their chances of ageing well.C. Annabel Streets is a student and often watches her mother care for her grandmother.D. Annabel Streets has to take care of four children.2. What should you do if you want to age well?A. You should walk in the morning.B. You should work at a less intense pace.C. You should read for more than 3.5 hours every day.D. You should work at a less intense pace and for fewer hours from mid-life on.3. What does the passage mainly talk about?A. Saunders found that people who worked longer lived longer.B. Saunders and Streets apply the healthy lifestyle to their own lives.C. Saunders and Streets’ experiences and ways to live well into old age.D. Streets found that those who read for more than 3.5 hours a week lived longest.BTribes(部落) in South Africa traditionally greet each other with “Sawabona.” which means “I see you.” The response is “Sikhona,” which translates to “I’m here.” As I watch my students finish up this busy school year, I’m making sure they feel that I know they are here at school and here in my life.At the beginning of the year, I ask my students’ parents to write me a letter telling me what they think I should know about their student. After all, they know their child best.One parent letter this year brought tears to my eyes.This mom wrote to me that when she asked her son about how he felt about his fourth-grade year, he got very quiet and wouldn’t look at her. When pressed, he eventually replied with tears streaming down his face and whispered, “No one saw me last year.” This inspired me to make this student (and all my students) feel seen this year.In spite of higher-class sizes and strict learning standards, I tried my best.My favorite part of every school day is that I stand at our classroom door to greet each and every student as they enter our room. It is important that I make a physical connection with each student in the form of a hug, handshake or high five. I make a verbal connection with each student as I check in with them. I ask about how their soccer game went, if they finished the homework, or if their grandma is feeling better. It only takes a few minutes but it pays back in priceless ways through relationships.I have two weeks left to connect with these students. I’m going to make the most of every minute I have left with them. To see them. To acknowledge that they are here.4. What inspired the author to make his students feel seen this year?A. One of his student’s tears.B. One of his student’s letter.C. One of his student’s homework.D. One of his students’ parent’s letter.5. The best title of the passage is ?A. Sawabona: I See You.B. Sikhona.C. a verbal connection.D. A hug.6. Which column(栏目) of the newspaper does the passage belong to?A. Health.B. Sports.C. Science.D. Education.第二节根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

单元达标测评(满分:120分;时间:100分钟)第一部分阅读(共两节,满分50分)第一节(共15小题;每小题2.5分,满分37.5分)阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项。
AConsidering that the Sundarbans National Park is situated in the tropics,September to March is the ideal time to come here.April,May and June are too hot while July and August often bring heavy season winds that limit travel and don't make for a very pleasant sightseeing experience.You can really enjoy doing lots of charming things in the Sundarbans during September to March.Take a river tourMost tourists who explore the Sundarbans arrive in Khulna City first.From there,you can join a boat tour that travels south along the Ganges River through miles of preserved forest all the way to Kotka,where there is a beautiful beach along the Bay of Bengal.Visit a bird habitatThis bird habitat is a nesting place for dozens of tropical birds found in the Sundarbans.The best way to observe these birds is climbing up the Sajnekhali Watchtower.If you're lucky,you'll also catch the famed BengalTiger making its rounds through the swampy jungle.Visit the Mangrove(红树林)Interpretation CentreIf you wish to spend some time indoors out of the sweaty heat,go to the Mangrove Interpretation Centre.This place is very educational with many posters,maps and exhibits showing wildlife and varieties of mangrove plants found within the park.You'll also get to see crocodiles in a small pool.Take a tour of local villagesExperience village life that has largely remained unchanged for centuries.In this vast tropical region,there are villages made up of various ethnic groups who rely on fishing,farming and working in the local through growing tourist industry for their livelihood. The Sundarbans is a UNESCO world heritage site where you can visit villages and talk to locals,from whom you can get cues about their culture.1.Which month is suitable for a visit to the Sundarbans National Park?A.December.B.August.C.June.D.May.2.What can visitors do in the Mangrove Interpretation Centre?A.See some plants and animals.B.Put up posters about wildlife.C.Feed crocodiles in a small river.D.Observe birds by climbing up the trees.3.What is the author's main purpose of writing the text?A.To advertise some natural animal habitats.B.To advocate the protection of forests in Khulna City.C.To introduce several charming villages in the vast tropical region.D.To show visitors something attractive to do in the Sundarbans.BBeing fat is a non-stop fight between not being noticed and attracting much notice. Sometimes you want to be accepted; instead, you're singled out and judged. In 2015, when I became the first plus-size designer to win Project Runway, I hoped it would be a moment not only for inclusive fashion, but also for all other fat human beings out there. It wasn't just me who had won; we'd won. Many women told me they were afraid to wear bright colors or show off their arms until they saw me doing it. But some of the words on the Internet were terrible: “Why did they pick that fat de signer?” “How can she encourage such an unhealthy lifestyle?” My positive psychology was affected. I got sad and negative and put on more weight. I reached a point where I couldn't climb stairs without losing my breath.I finally realized that if I didn't take care of myself, I couldn't keep doing what I loved, so I went to see a doctor and started doing exerciseevery day. After that I got more judgments, this time from people in the fat group who once supported me. They turned their backs on me and said, “You can't be body positive and still losing weight.” I thought, “Well, why not? I wasn't trying to be ‘prettier’; I wanted to have control of my life.”Size should not divide us, whether we are fat, thin, or anywhere in the between. I'm designing clothes for plus women, but one day I might be open to designing straight(直筒型的) sizes. People judge me for that, too. But I just want to create clothes that make people feel good. I want every woman to love herself and go after her dreams like I did.4.What was the author's hope after she won Project Runway?A.People would look up to her.B.Other fat people would share her pride.C.The clothes she designed would sell well.D.Fat people would lead the fashion industry.5.What did the author do after she saw the words on the Internet?A.She lost interest in fashion.B.She lost control of her body.C.She stopped wearing bright colors.D.She decided to have a healthy lifestyle.6.What was fat people's attitude to the author when she started losing weight?A.Dissatisfied.B.Uninterested.C.They laughed at her.D.They couldn't believe it.7.In which part of a newspaper might this passage appear?A.Environment.B.Medicine.C.Career.D.Entertainment.CWhen we talk about positive thinking, we often use terms having to do with our hearts—open heart, pure heart or joyful heart. But new research from Duke University is making a closer connection, finding that a positive attitude may be helpful to people who have angina (心绞痛),a common heart condition.Symptoms of this condition include chest pain or pressure because the heart is not receiving sufficient oxygen. Patients who displayed optimistic thought patterns, including having positive expectations about recovery, were 40 percent less likely to be hospitalized or require surgery than those who were not optimistic, according to the study. The researchers collected data from 2,400 patients who had diagnoses of angina.An interesting additional finding from the patients' questionnaires was that the most optimistic patients were also the least likely to havehistories of heart attack, heart failure or heart disease.The researchers did not declare a causal relationship between positive thinking and better heart disease outcomes, however. There are multiple possible reasons for the results of the study, including the idea that patients who are healthier to begin with are more likely to expect to recover and regain good health.But the study does represent a new way of looking at the situation. Now, in addition to a body of research that examines the relationship between depression and heart health, there is a new way of inquiry that asks whether positive thinking could be used as a strategy to improve outcomes.Lead researcher Alexander Fanaroff, a fellow in the department of cardiology (心脏病学) at the Duke University Medical Center, told the Duke Chronicle that his next research question will find ways to improve attitudes among heart patients.Perhaps his subjects could reflect on the words of the writer Anthony J. D'Angelo:“Smil e—it is the key that fits the lock of everybody's heart.”8.How can people with angina get better according to the study?A.By expecting more.B.By thinking positively.C.By getting timely surgery.D.By taking more exercise.9.What may be Alexander Fanaroff's next research?A.To explore how to improve patients' attitudes.B.To find out the ways to treat heart patients.C.To learn the causes of heart diseases.D.To test if positive attitudes help with health.10.What can we learn from the text?A.Optimistic people hardly get heart attack.B.People's attitudes decide their overall health.C.How positive thinking benefits heart health is unclear.D.The reason why patients recover well is that they have no depression.11.What may be the best title of the text?A.Keep positive to get rid of illnessB.Angina, a kind of serious conditionC.Depression, a key cause of heart attackD.Positive thinking makes hearts healthierDNext time you're in a public place, take a look around you, and count how many people are using their phones. I can tell you now that it is probably more than half, whether you're on public transport, in a cafe or simply standing on an escalator.I'm not saying that I am not an example of this, but it always amazes me how people can spend so much time on their phones without actuallytalking to anyone in particular. It seems that they rely on their phones too much.For example, I recently visited London and travelled on the tube while I was there. Apart from the people asleep, almost everybody else was on their phones, and because of the nature of the tube, it is difficult not to see exactly what they are all doing. Of course, being underground is difficult for you to get any signal, which rules out texting or using the Internet, but there is still plenty you can use your phones for. People were absorbed in playing games, reading articles and listening to music, and I am sure that as soon as they emerged from the train station they would start texting or calling or checking their emails.Recently, my smartphone broke and had to be sent off to the warehouse for repair for a week or so. In the meantime I had to use a really old, basic phone just to keep me in touch with my family and friends. All I could do on this phone was send text messages, make calls and play one game. And I loved it. I loved being free from the Internet, and I really didn't mind not having constant updates about what my friends were doing or what the latest celebrity story was. It allowed me to spend more time taking in my surroundings.However, I knew that as soon as I got my smartphone back I would be one of those people once again. But I made up my mind to discipline myself.12.Why are you asked to look around in Paragraph 1?A.To ensure your safety.B.To communicate with people.C.To count the people around you.D.To count the number of people using phones.13.What were many people on the tube in London probably doing?ing mobile apps.B.Talking with each other.C.Reading printed books.D.Checking social network sites.14.What did the author think of having to use his basic phone?A.He felt great actually.B.He found it very inconvenient.C.He couldn't see much difference.D.He felt terrible at first but better later.15.What does the underlined part “those people” in the last paragraph refer to?A.People without mobiles.B.People using basic phones.C.People using smartphones reasonably.D.People spending a lot of time on mobiles.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。

fighting for women to be treated equally.In doing so,she became an inspiring role model for women and girls around the world.Her passion for women’s rights began when she was young.She started off her adult life having trouble finding a job.Even though she was smart,determined,and capable of doing the job,she was passed over primarily because she was a woman.She felt like she was being treated unfairly,only because she was a woman.She wanted to do something about it.But at the time there were no laws in the United States to protect her.She decided to devote her career to being a lawyer and fighting for equal rights of women.Then,early in her legal career,when she was 29 years old,Ms.Ginsburg took a trip to Sweden to perform legal research.What she saw really focused her on fighting for women in the workplace.Seeing the progress women had made in Sweden convinced her even more that America was behind and wrong in its treatment of women.Back in the USA,laws advocating for women’s rights were missing.She decided that she would help invent laws,write them,and defend them.Ginsburg would also become a professor to help other women to become lawyers so that they could do the same thing.Andthen,in 1993,after years’ practicing and teaching laws,she becam e only the 2nd female justice of the Supreme Court.At only 5'1″ tall and as a generally quietperson,Ms.Ginsburg’s power came

would be happy about.Hassel was surprised,however,when her little girl threw the case in the garbage and stormed into her bedroom,slamming the door behind her.“She yelled,‘That’s stupid.Everyon e in my class has that...I don’t want it anymore!’”Hassel explained in a post.Hassel said she didn’t immediately react because she wanted to deal with the anger properly.“So by the time there was probably smoke coming out of my ears,I was trying really hard not to completely lose it with this kid whom I have worked so hard to completely take care of on my own,”she wrote.“I thought I had always taught her to be grateful and know how lucky she was,but she needed a small wake-up call!”Hassel grabbed a plast ic sandwich bag,wrote Presleigh’s name on it and handed it to her.“I told her to get the pencil case out of the trash and that we would give it to one whose mommy and daddy don’t have money for any school supplies or someone who may not even have a mommy or daddy.”She continued,“I explained to her she’s not entitled to(享有)anything special and she is taking for granted how lucky she is.So for now she will be using a bag and will personally be delivering the nice bo it.”8.What

Hassel?A.Patient and calm.B.Out-going and active.C.Funny and brave.D.Hardworking and determined.DIf you thought running was just great for the body,then think again.Scientists have found that the sport not only keeps people fit but also improves their brain power (脑力).The research found that people who keep fit are more likely to have larger brains,better memories and clearer thinking.They also found that unfit people tended to have smaller brains and reduced cognitive skills.The findings add to a growing body of evidence which links exercise with helping protect the brain against ageing (老化) and also helping it replace dying cells (死细胞).This might reduce the risk of many illnesses and diseases such as Alzheimer’s.One research paper within its latest issue sees scientists at Kentucky University putting 30 adults aged 59-69 on a treadmill (跑步机).Their heart and lung capacity was measured and an MRI scanner was used to assess the blood flow to their brains.Those who were less fit had smaller brains compared to the fitter volunteers who had larger brains.Scientists in Germany followed 21 adults aged between 60-77.As they went through a three-month fitness program,they saw improvements in their memory.Researchers are not yet sure why exercise helps to protect brain cells but some research in mice has produced results.Mice,examined at the National Institute on Ageing,in Baltimore,found that cells in the hippocampus (海马体),an area of the brain used for memory,were actively reproducing while their fatter peers were in decline.Linda Clare,professor of clinical psychology of ageing and dementia at Eember of the Global Council on Brain Health told TheSundayTimes,“Moderate intensity aerobic (有氧的) activity such as walking,cycling or running can produce changes

It will last for four days.BIt was perhaps the worst time for Kevin Butler. It was on the morning of Nov. 23. Butler's wife, Cindy, had cleaned her rings and left them in a napkin (餐巾纸) to dry on the kitchen counter. Butler threw the napkin into a trash (垃圾) bag. He'd then taken the bag to the transfer station (垃圾中转站). Shortly after, as his wifenervously searched the house for her rings, Butler realized where the missing rings might be: “I've got a feeling they're in the trash,” he told her. Butler rushed over to the transfer station around 2 p.m. knowing the chances of finding the rings were small. But still worth a try.As he told the workers there what had happened, Butler appeared “a little nervous,” said Senibaldi, the general services director for the town. “I could see in his eyes that he was stressed.”Luckily, the trailer (拖车) including Butler's bags had not yet left the site. Once they tracked down the trailer, the search began for Butler's specific trash bag. It was a team effort to check all the waste — which totaled 40,000 pounds, in the trailer. Other workers saw what was happening and came over to help. They all knew it would take a long time.“It was like looking for a needle in a haystack,” Butler said. “I thought they were gone because we were just about done, and there was nothing there.”“Then Senibaldi saw the two rings sitting in the bottom of a bag,” Butler said. “I lost my mind, and I gave him a big hug.”Everyone had big smiles, and they all celebrated together. “I'm glad that the town of Windham and the transfer station are getting this positive publicity. It was truly something to be thankful for,” saidButler, explaining that he was touched by the workers who helped him.24. What did Butler do on the morning of Nov. 23A. He picked up rings in the trash.B. He helped his wife clean her rings.C. He mistakenly threw his wife's rings away.D. He asked his wife for help dealing with the trash.25. What happened after Butler rushed to the transfer stationA. The trailer started to pull away.B. He located his trash bag at once.C. He shared his experience calmly.D. The workers teamed up to give him a hand.26. What does the underlined sentence in paragraph 4 meanA. It was a tiring day.B. It was a costly effort.C. It was a sharp lesson to learn.D. It was almost impossible to find.27. What did Butler think of the workersA. Careful.B. Successful.C. Admirable.D. Responsible.CArcher Calder spent his childhood unable to talk with his younger sister, Della.Della has Bainbridge-Ropers syndrome, a condition which affects her ability to speak. In her early teens, she was introduced to augmentative and alternative ( 增强型和替代型) communication (AAC) applications, programs designed to help people who have trouble with speech or language skills. Some applications were quite expensive, but her family was upset about the results.So Archer began using his coding ( 编程) abilities to help his sister communicate. The boy developed a web - based application called Freespeech. The site can be accessed from any device ( 设备) —phones, tablets and computers — with Internet access. The simple website lets users program buttons with pictures of their choice to represent words. When clicked, the word is sounded out loud. Unlike many other AAC applications, Freespeech's buttons are easily editable, a feature Archer believed was important to how Della wanted to communicate.It wasn't long before the Calder family noticed a change in how Della was able to communicate with them. “In the past, when we had to go somewhere, we just took her. She never really discussed it with us,” the father said. “Freespeech has really helped to bringher more into the conversation and more into the life of our family.” The family says it has also helped them discover more of her personality.Archer made his website free for anyone to use and posted it on TikTok, hoping it might reach other families like his who might find it useful.For Archer, Freespeech is still a work in progress. He's now working on plans to make the software convenient to use without an Internet connection, something he sees as a disadvantage.He said he's encouraged to keep working on the project, not only for Della, but by the people who have since reached out to share how the app has helped their own families.28. How did Archer feel about some of the AAC applications his sister used at firstA. They were cheap but useless.B. They were uncomfortable to use.C. They were unsatisfying and costly.D. They were helpful but too expensive.29. What is a major advantage of Freespeech over other AAC applicationsA. It has a free Internet connection.B. It uses pictures instead of words.C. It can be used on different platforms.D. It allows users to personalize buttons.30. How has Freespeech affected DellaA. She has become interested in coding.B. She has developed a stronger personality.C. She has learned new communication skills.D. She has taken part more in her family life.31. What does Archer plan to do with his applicationA. Make it free to use.B. Make it usable offline.C. Improve its sound system.D. Share it with other families.DJason M. Allen of Pueblo West, Colorado, began experimenting with AI-generated ( 人工智能创作的) art this year. This summer, he saw people testing Midjourney, which uses a process to turn text into custom images. Finally, Allen got the idea to give one of his Midjourney creations to the Colorado State Fair. Several weeks later, while walking around the fairground in Pueblo, Allen found he had won, along with a $300 prize.After his win, Allen posted a photo of his prize work online. It made its way to Twitter, where many people expressed their disapproving( 反对的) attitude. “We're watching the death of artistry,” one Twitter user wrote. Another wrote: “I can see how AI art can be beneficial, but saying you're an artist by generating one Of course not.” Some artists stand with Allen, saying that using AI to create a piece was no different from using Photoshop or other tools and that human creativity is still required to generate an award-winning piece.Controversy ( 争论) over new artmaking technologies is nothing new. Many painters feared the invention of the camera, which they saw as a debasement (降低) of human artistry.What makes the new kind of AI tools different, some people believe, is not just that they're able to produce beautiful works of art with little effort, but how they work. “What makes this AI different is that it's trained on working artists,” RI Palmer, a digital artist, tweeted last month. “This thing wants our jobs; it's actively against the artist.”Allen said he understood artists who feared that AI tools would put them out of work. But “People should only be unsatisfied with the technology itself,” he said. “The ethics (伦理学) isn't in the technology. It's in the people.”And he strongly suggested artists deal with their fear of AI. “This isn't going to stop,” Allen said. “Art is dead. It's over. AI won. Humans lost.”32.

2018版高中英语(人教版)必修3同步练习题：Unit 2 单元综合测评
单元综合测评Ⅰ.阅读理解(共15小题；每小题2分，满分30分)AIt seems school children all over the world complain about their school food.Cherie Blair, the wife of former British Prime Minister Tony Blair, said that she would prepare a packed lunch for her son if school dinners do not improve.So what do students of your age eat for lunch at school?JapanHigh schools have canteens(餐厅), which serve everything from noodles to rice, but not burgers and chips.Other children bring food from home such as cold rice balls, meat or fish, pickles(泡菜) and vegetables.Students take home a menu for the coming month containing notes on nutrition value.Twice a year parents are invited to have a taste of the food.The class with the fewest leftovers(剩饭) at the end of the month receives a prize.United StatesA typical menu from a US school is made up of a hamburger with fried potatoes or roast chicken, lettuce and pickles, fruit and cookies.School lunches must also provide at least one-third of the daily dietary allowances(定量) of protein, vitamin A, vitamin C, iron, calcium and calories.AustraliaMeat pies, sausage rolls and hot dogs are all traditional dishes in Australian school shops.But as the nation pays more attention to children's health, healthier foods have started to find their way onto school menus.Many schools have used a traffic light system.The sale of red-labelled(标签) foods, including pastries, chocolate and soft drinks, is served only twice a week.Healthier green-labelled foods such as sushi, sandwiches, corn and watermelon, however, are available every day.In some schools, students have a choice of up to 89 foods to choose from, including popcorn and rice.South AfricaMost of South Africa's schools do not serve meals at all.Classes end at 1：30 p．m.and students get their own lunches.Many students bring food from home, usuallysandwiches.Fast food and fried food sell the best among students, which has led to a rise in obesity among children.But as more people began to realize the fact that being too fat may cause different diseases, some schools in towns have led the way towards better nutrition(营养)．Now students at these schools are provided with lunches of porridge(粥) with vegetables, such as cabbages, onions, beans, carrots and tomatoes.【语篇解读】本文是一篇说明文，主要介绍了世界各地的学生不同的午餐。

[课下综合检测]一、单项选择题1．(2013·海南高考)关于植物激素的叙述，错误的是()A．植物激素的产生部位和作用部位可以不同B．植物茎尖的细胞可利用色氨酸合成生长素C．细胞分裂素和生长素可以在同一细胞中起作用D．生长素可通过促进乙烯合成来促进茎段细胞伸长解析：选D植物激素的产生部位和作用部位可以不同，如胚珠产生的生长素可促进子房发育成果实。
生长素主要在幼嫩的芽、叶和发育的种子中由色氨酸经过一系列反应转变而成。
细胞生命活动是由多种激素共同作用的结果，细胞分裂素和生长素可以在同一细胞中起作用。
生长素可通过促进乙烯合成来抑制茎段细胞伸长。
2．某生物兴趣小组利用玉米胚芽鞘做了如下图所示的实验。
对该实验的相关叙述正确的是()A．该实验在黑暗中完成，为防止单侧光照射引起生长素向背光一侧运输B．引起③④弯曲生长的原理与单侧光照射使胚芽鞘弯曲生长的原理相同C．实验结果证明了尖端产生的某种物质具有极性运输的特点D．实验结果表明胚芽鞘尖端产生了某种物质能促进尖端以下部分的生长解析：选D该实验中胚芽鞘尖端已经去除，单侧光照射也不会引起生长素向背光一侧运输，黑暗中实验的目的是防止无关变量对实验结果造成影响；单侧光照射使胚芽鞘弯曲生长的原理是生长素在尖端横向运输，导致背光侧分布多，植物表现向光性，而引起图中③④弯曲的原理是琼脂块放臵位臵，导致生长素分布不均，两者原理不同；实验中没有研究物质的运输问题，无法得出尖端产生的某种物质具有极性运输的特点；通过琼脂块的实验，结果表明胚芽鞘尖端产生了某种物质能促进尖端以下部分的生长。
3．下列关于生长素的叙述，不．正确的是()A．在植物体内可以进行极性运输和非极性运输B．在植物体中含量很少，主要分布在生长旺盛的部位C．既可以直接参与代谢，又可以给细胞传达调节代谢的信息D．对于根和茎的生长都是低浓度促进生长，高浓度抑制生长解析：选C单侧光照射引起的生长素由向光侧向背光侧转移属于非极性运输；生长素由形态学的上端向形态学的下端运输属于极性运输。
生长素在植物体中含量很少，主要分布在生长旺盛的部位，如根尖、茎尖。
生长素是生长调节物质，不能直接参与代谢。
生长素的作用具有两重性，对于根和茎都是低浓度促进生长，高浓度抑制生长。
4．(2013·广东高考)下图为去顶芽对拟南芥主根生长影响的实验结果，分析正确的是()A．去顶芽能促进主根生长B．去顶芽植株不能合成生长素C．生长素由顶芽向下非极性运输D．外源生长素能替代顶芽促进主根生长解析：选D去顶芽植株和正常植株相比，主根长度小，说明顶芽能促进主根生长；去顶芽植株＋外源生长素与正常植株相比，主根长度大致相同，说明生长素能替代顶芽促进主根生长；去顶芽植株主根还能生长，说明去顶芽植株仍能合成少量生长素；生长素由顶芽向下运输属于极性运输。
5．春季水稻种子播种前，可用含赤霉素的温水浸泡种子。
下列有关叙述正确的是() A．该处理的目的是对水稻种子进行消毒B．该处理有利于提高种子内合成淀粉的酶的活性C．成熟种子内无赤霉素，故需用一定浓度的赤霉素溶液浸泡种子D．处理过的种子堆内温度升高加快是由于细胞呼吸放热加快引起的解析：选D用含赤霉素的温水浸泡种子的目的是解除水稻种子的休眠；该处理有利于提高种子内水解淀粉的酶的活性；成熟种子内也有赤霉素；处理过的种子堆内温度升高加快是由于细胞呼吸放热加快引起的。
6．(2014·苏北四市调研)生长素类似物2,4-D能除去单子叶农田中的双子叶杂草。
为了研究不同浓度的Basta除草剂(作用机理类似于2,4-D)对普通玉米、转Bar抗除草剂基因(能表现出对Basta的抗性)玉米及玉米地中双子叶杂草X生长的影响，研究小组进行了有关实验，得到如下曲线。
则图中与普通玉米、转Bar抗除草剂基因玉米及双子叶杂草X对应的曲线分别为()A．甲、乙、丙B．丙、乙、甲C．乙、甲、丙D．乙、丙、甲解析：选D转Bar抗除草剂基因玉米对Basta除草剂最不敏感，对应丙曲线；玉米地中双子叶杂草对Basta除草剂最敏感，对应甲曲线；普通玉米对Basta的敏感性介于两者之间，对应乙曲线。
7．(2012·江苏高考)下列关于植物激素或类似物的叙述，正确的是()A．脱落酸能够调控细胞的基因表达B．杨树顶芽的快速生长需要侧芽提供生长素C．喷施生长素类似物可以保花保果但不能疏花疏果D．密封贮藏导致水果各种激素合成增加解析：选A秋季时，随着光照、温度等环境因子的变化，一些植物体内脱落酸等物质的合成量也会发生变化，进而对基因组的表达进行调节，从而促进叶片的衰老、脱落；杨树顶芽的快速生长是因为顶芽部位生长素浓度低，有促进作用；生长素类似物的作用具有两重性，既能防止落花落果，也能疏花疏果；密封贮藏水果时生长素的合成量并未增加。
8．为探究小麦根、芽对生长素敏感性的差异，某生物兴趣小组以不同浓度的NAA处理萌发的小麦种子，8d后分别测定小麦幼苗根、芽的长度，结果如下表。
下列说法不．正确的是()B．促进根伸长的最适NAA浓度小于芽，根对NAA 的敏感性大于芽C．低于最适浓度时，NAA对根的促进效应随浓度的增加而加强D．0.1 ppm 的NAA对根、芽的作用效应，体现了NAA作用具有两重性解析：选D每组实验处理多粒种子，然后获得根、芽的平均长度，这样能保证数据的真实性和可靠性；表中促进芽生长的最适浓度在0.1 ppm左右，促进根生长的最适浓度在0.001 ppm左右，故根对NAA 的敏感性大于芽；低于最适浓度时，NAA对根的促进效应随浓度的增加而加强，超过最适浓度后，随NAA浓度的增加促进效应下降；0.1 ppm 的NAA 对根、芽的作用效应，体现了同一浓度的NAA对不同器官的作用效果不同。
9．(2013·徐州宿迁三模)关于探究吲哚丁酸(IBA)促进月季插条生根最适浓度的实验中，错误的是()A．实验用的月季枝条最好是生长旺盛的一年生枝条B．要将月季枝条上的叶和芽全部去掉以保证无关变量相同C．在处理月季插条时，用低浓度的IBA浸泡插条基部D．实验结果中可能存在促进生根效果相似的两种不同浓度解析：选B生长旺盛的一年生月季枝条，细胞分裂能力较强，有利于生根；月季枝条上一般要保留3至4个芽，且保留的芽数相同；低浓度的IBA 促进月季枝条生长，有利用于月季枝条生根；由于IBA 是生长素类似物，低浓度促进插条生根，有一最适促进插条生根的浓度，低于或高于最适浓度促进作用都减弱，因此在最适浓度两侧，存在促进生根效果相同的两种浓度。
二、多项选择题10．在番茄植株生长的不同季节，使用不同的植物激素可以有效促进番茄的生长和提高产量。
下表中对番茄不同生长时期使用的植物激素及使用目的的描述错误的是()用适宜浓度的乙烯，可以促进果实的成熟。

11．(2014·苏、锡、常、镇四市调研)下图是某生长素类似物在N1、N2和N3三种浓度下对微型月季茎段侧芽生长的影响图。
据图判断下列有关叙述正确的是()A．随着生长素类似物浓度的升高，微型月季茎段侧芽的生长量越大B．N1浓度的生长素类似物对微型月季茎段侧芽生长具有抑制作用C．生长素类似物的N3浓度可能小于N2浓度D．N3浓度一定是促进微型月季茎段侧芽生长的最适浓度解析：选BC生长素作用具有两重性，当超过一定浓度时，随着生长素类似物浓度的升高，茎段侧芽的生长量反而会减少；N1浓度的生长素类似物处理的微型月季茎段侧芽生长量小于空白对照，说明该浓度对其生长具有抑制作用；根据生长素作用的特点，N3浓度可能小于N2浓度；只有三种浓度，不能说明N3浓度一定是促进微型月季茎段侧芽生长的最适浓度。
12．(2013·南通三模)科研人员研究了单侧光对水稻根生长的影响，得到下图1 、2所示的实验结果。
相关叙述正确的是()A．根的生长具有负向光性B．根生长过程中只受单侧光刺激C．图2现象可能与生长素分布不均匀有关D．实验结果说明感受光刺激的部位是根尖解析：选AC分析图1、2 可知，在有单侧光照射下，植物的根向背光处生长，说明根的生长具有负向光性；根的生长除受单侧光刺激，还会受重力等因素影响；图2现象可能是根部生长素分布不均匀，背光侧生长素分布过多，抑制了根的生长，导致根的生长具有负向光性；该实验没有设臵研究感光部位的实验，无法说明感受光刺激的部位。
三、非选择题13．下面是三组研究生长素的实验设计示意图。
(1)根据实验一的结果可知，切除胚芽鞘尖端的胚芽鞘向左弯曲生长，其生长素最终来自________________________________________________________________________。
(2)如果实验一是为了研究胚芽鞘尖端能产生生长素，且能促进胚芽鞘下端生长，应补充的对照实验是___________________________________________________________________________________________________________________________________。
(3)实验二中的明显错误是______________________________________________。
(4)如果利用实验三研究单侧光引起胚芽鞘尖端生长素分布不均匀，请补充完善实验三中的甲、乙两图。
解析：(1)实验一中，切除尖端的胚芽鞘的右侧放臵用尖端接触过的琼脂块后，胚芽鞘向左弯曲生长，其生长素来自胚芽鞘尖端。
(2)实验一中再添加一组：将未接触过胚芽鞘尖端的琼脂块，放在切除胚芽鞘尖端的胚芽鞘的右侧，最终胚芽鞘不生长，由此说明胚芽鞘尖端能产生生长素且能促进下部生长。
(3)实验二的结果预测错误，胚芽鞘应向左弯曲生长。
(4)实验三对甲组处理是在胚芽鞘尖端下侧放臵琼脂块A、B，并用单侧光照射尖端，使背光侧琼脂块中含有的生长素多于向光侧，然后臵于切除尖端的胚芽鞘右侧，观察两组胚芽鞘的生长状况(乙)。
答案：(1)胚芽鞘尖端(2)将未接触过胚芽鞘尖端的琼脂块，放在切除胚芽鞘尖端的胚芽鞘的右侧(3)实验结果应该是胚芽鞘向左弯曲生长(4)如下图：14．(2013·南京二模)为研究生长素类似物2,4-D对某植物插条生根的影响，实验小组按下表进行了实验，请分析回答：(1)设置A组实验的目的是__________________________________________________。
