During this period, I have given out over 200 smile cards. I have always tried to find something kind to do, even when my husband lost his job and we were fighting to get by.I have started giving out coupons (赠票) for free food and money for people to get at least one meal. I always put my coupon, gift and smile card in an envelope that says “For whoever finds this”.Once I left an envelope on someone’s work truck and got back into our trailer. I just happened to look out at the truck later and I saw the guy open my envelope and find the gift. He read the card and then he looked around to see who had done this. I just smiled to myself, without being found out. I always leave my gifts where people can find them, but never see me do it — I like it to be anonymous.Today I saw a car on the side of the highway with the hazard lights (危险信号灯) on. Further up the road, I saw a young couple walking beside the highway. I pulled over and asked them if they needed a ride to the next exit; after a second the guy said they could really use the ride. They said “thank you” when I dropped them off at the exit. I try to help others when I can, and sometimes no smile card is needed or given.It’s my little “game of good” and I really enjoy doing it and I hope to keep doing it!36. From the first two paragraphs, we can learn the writer .A. gives out smile cards every dayB. lives a hard life with her familyC. is out of work for two and a half yearsD. tries to do something special37. When the guy found the envelope, he .A. smiled to the writerB. threw it out of the truckC. was surprised and looked aroundD. went to the store to buy some food38. The writer mentions the incident on the highway in order to .A. prove she really enjoys helping young peopleB. tell us she gains a lot from helping other peopleC. show she takes any opportunity to help othersD. advise us to help those standing beside the highwayBEmpty lands in cities and towns around the United States are finding new life as urban farms.Eco City Farms in Edmonston, Maryland, is located near shopping centers, car repair shops and homes. The neighborhood is a working-class community where people do not have very much money, and they have limited access to fresh food in markets.Over the past two years, the farm has attracted lots of volunteers from the community like Mary Clark. She schools her four children at home. On a recent day she brought them to Eco City Farms for a lesson.Mary Clark says, “It’s important that the children understand the connection between the food that they eat and the soil, the air and the pollution.” What did Hannah, Caleb, John and Alston think of the experience?Hannah Clark, “You know, it’s good for the earth and it’s good for us.”Caleb Clark, “It may not be like fun, but it’s fun, because you’re learning and not like writin g something out on a piece of paper.”John Clark, “Basically instead of feeling down when I have to eat vegetables, I feel happy.”Alston Clark, “I like coming out here. You know, you connect with the earth, where your food comes from. You appreciate the f ood a little bit more.”Margaret Morgan-Hubbard started Eco City Farms. She thinks of it as a place where people can learn to live healthier lives. She says, “Our view is that what happens in a community influences the culture of that community. So our idea was growing food in a community and showing that you can have farms even in urban areas.”39. We can learn from the passage that Eco City Farms .A. is located near the countrysideB. really attracts many people in the communityC. is a place where people can be schooledD. is a place where people can play different games40. Which of the following children usually hates vegetables?A. Hannah Clark.B. Caleb Clark.C. John Clark.D. Alston Clark.41. According to Margaret, Eco City Farms in Edmonston was started to .A. bring all the community members togetherB. develop the culture of farming in a communityC. offer the neighborhood the access to fresh fruitsD. help people in the community live more healthily42. The passage is a report about .A. educationB. scienceC. agricultureD. healthCA dog which disappeared nine years ago has been found. Muffy is to be returned to her owners when she is fit to travel. The dirty white Muffy was discovered sleeping on a box of cardboard in Melbourne by officials from the RSPCA who were looking into a possible animal cruelty (虐待) case.A microchip in her neck helped find her original(原来的) owners and after a few days of searching for the phone number, officials found Natalie Lampard, who had given up hope of seeing Muffy again since she went missing years ago.“When the RSPCA described her, I told them her name; I knew immediately it was our Muffy,” Ms Lampard said. “It was totally out of the blue —after nine years, I thought she was long gone.”The owners of the Melbourne house where Muffy was discovered said they found the dog about a year ago wandering along a street. But where Muffy spent the eight years and how she ended up in Melbourne is a mystery. RSPCA spokesman Tim Pilgrim said, “Nobody knows; the mystery continues for old Muffy.” The dog was suffering from a serious i llness and had been having treatment since she was discovered.The dog, which Lampard adopted (收养) from an RSPCA shelter near Brisbane, is recovering well and will fly back home next week. Ms Lampard got Muffy as a gift for her now 17-year-old daughter Chloe, and the two had been inseparable (不能分开的).“After the RSPCA called, I rang my daughter and asked her if she was sitting down, then told her they’d found Muffy,” she said. “She is over the moon and there’ll be a few tears shed when they see each other ag ain.”43. We can learn from the first paragraph that the RSPCA is .A. a place where many animals are keptB. the police station that catches thievesC. the government that serves the citizensD. an organization that protects animals44. What does the underlined phrase “out of the blue” in Paragraph 3 mean?A. Amusing.B. Unexpected.C. Funny.D. Strange.45. What surprises people most is .A. that the dog has returned to its home after nine yearsB. how the dog survived and came to MelbourneC. how the dog has run across Australia in 8 yearsD. that the dog remains very strong after nine years46. Ms. Lampard adopted the dog because .A. she liked raising dogs very muchB. she cared for and protected animalsC. she gave her daughter the dog as a giftD. her husband wanted to have a white dogDMy friend Brett had just gotten a dirt bike (泥土路摩托车) and a lot of other kids in my neighborhood knew how to ride. I also wanted to, but I didn’t even know the difference between the clutch (离合器) and the front brake. All the guys told me I couldn’t do it because I was a girl. I was determined to prove them wrong, so Brett let me try his bike. I wasn’t on for one minute before I fell off. He came over to see if I was okay, but then started laughing. I felt like running somewhere I wouldn’t be laughed at.That night I told my dad the whole story about how I wanted to be as good as the guys and how I had embarrassed myself. He asked how much I really wanted to learn, then I told him I had wanted to ride for a year and it was everything I dreamed about.A few days later my dad told me he’d found a nice bike for a reasonable price. He brought it home and that was when I became the laughing stock of the neighborhood. All the guys thought it was a joke that I actually wanted to learn how to ride and I became known as a wannabe (模仿偶像者).We took it one step at a time. My dad spent four long weeks teaching me everything I needed to know about the bike and the basics of riding. No one truly believed I could learn to ride except my dad. Day after day and night after night he worked with me, and I began to progress. I was so thankful. It meant so much that he would take time from his busy schedule to help me fulfill this dream.Each ride on my dirt bike, I got a little better, and finally I was ready for my first time on the trails. At first I couldn’t keep up and the boys had to wait for me. My bike constantly stalled and got stuck in the muddy creeks.Things eventually got easier, as if I could ride with my eyes closed. Every time I rode on the trails I got a little better and the guys didn’t have to wait for me. I was still made fun of, not because I was an amateur or not good, but instead because they felt threatened that a girl could do what they did.I cannot even remember how many nights I spent crying when I had lost my confidence because of those boys. Every time I needed a shoulder to cry on, my dad was there. He never let me give up and always had faith in me, even if I couldn’t do something right.47. Why does the author write the passage?A. To show the difficulty in riding a dirt bike.B. To prove that girls can do whatever boys can.C. To thank her father for his trust and support.D. To share her experience in riding a dirt bike.48. Brett let the author try his bike because .A. he was sorry for laughing at herB. he felt her strong determinationC. he was the kindest boy in the groupD. he wanted to show other guys were wrong49. Why did the boys still make fun of the author when things got easier?A. The author looked stupid.B. They felt the threat from her.C. The author always fell behind.D. They didn’t want to ride with her.50. Which of the following best describes the author?A. Shy.B. Self-confident.C. Weak.D.

的元素个数为有限个. 综上所述，当0k ≥时，集合A 的元素个数为无限个，当k 0<时，集合A 的元素个数为有限个，故当k 0<时，集合A 的元素个数最少，且当6k k+的值越大，集合A 的元素个数越少，令6()f k k k =+（k 0<），则26()1f k k'=-，令()0f k '= 解得k =()f k在(,-∞内单调递增，在()内单调递减，所以max ()(f k f

=-∞+∞，结合[1,2]BA =R的意义，可得集合A . 【详解】因为集合A 、B 是实数集R 的子集，若AB =∅,则[2,0]AB A =-=R，[1,2]BA B ==R，但不满足()()[3,5]A B =R R ，所以A B ⋂≠∅.因为()()[3,5]A B =R R ,所以()()()[3,5]AB A B ==R R R ，所以有()(),35,A B =-∞+∞.又因为[1,2]BA =R表示集合B 的元素去掉集合A 中的元素，()(),35,A B =-∞+∞表示A 集合和B 集合中的所有元素，所以把()(),35,A B =-∞+∞中的元素去掉[1,2]BA =R中元素，即为所求的集合A ，所以(,1)(2,3)(5,)A =-∞+∞.故答案为(,1)(2,3)(5,)-∞+∞.【点睛】本题主要考查集合的运算，根据集合的运算性质可求也可借助数轴或者韦恩图求解，侧重考查逻辑推理的核心素养.20．49【分析】分中的最大数为中的最大数为中的最大数为中的最大数为四种情况根据题意列举出满足条件的集合即可得出结果【详解】当中的最大数为即时；所以满足题意的集合对的个数为个；当中的最大数为即时；即满足题解析：49 【分析】分A

Understandably, archaeologists and other __48__ wanted to knowmore about the person that they called, “ LindowMan ” His. hands and fingernails suggested that he hadn’ t done heavy __49__ work in this lifeh could have been a—rich man. They found that he hadn’ t died by accident. The archaeologists believe that he was sacrificed to three different gods.III.

This camping trip idea is not gettingoff to a very good start. It's raining and the tent leaks. The hiking seemed to take forever,and I still can't understand how it could all have been up hill! How did I ever let mybrother talk me into this? When we get home —if we ever get home — he's going to have to do something great to get back on my good side. Maybe he should sponsor a shopping spree （狂购） at the mall!Tuesday: Things are looking up. The sun came out today, so we were able to leave the tents and dry out. We're camped at the edge of a small lake that I couldn't see before because of the rain and fog. The mountains are all around us, and the forest is absolutely beautiful. We spent most of the day dragging everything out of our backpacks or tents and putting it where the sun could dry it out. Later in the afternoonwe tried to catch the fish for dinner, but the fish were smarter than we were. Atnight we built a fire and sang songs happily.Wednesday: We hiked to the far side of the lake and climbed to the top of asmall peak. From there we could see how high the other mountains were and how farthe forest spread around us. On the way up we passed through a snowfield!Thursday: I caught my first fish! We followed the stream that fed the lake. Afterabout two miles, we came to a section that Carol said looked "fishy". She had a packrod （竿）, which can be carried in a backpack. I asked to cast it, and I caught a fish onmy first try. Carol caught a few more. But they were just too pretty to eat for lunch, so weput them back in the stream.Friday: I can't believe we are going home already. It will be nice to get a hot shower,sleep in a real bed, and eat junk food, but the trip has been wonderful ． We're already talking about another camping adventure next year where we canoe down a river. It'shard to believe, but I think this city girl has a little country blood in her veins.65.

Without themetropolis, we might not have had the great art of Shakespeare.And yet, city life isn’ t easy. Now scientists have begun to examine how the city affects the brain, and the results are depressing. Just being in an urban environment,they have found, impairs (伤害 ) our basic mental processes. After spending a few minutes on a crowded city street, the brain is less able to hold things in memory, andsuffers from reduced self- control. While it’longs been recognized that city life isexhausting, this new research suggests that cities actually dull our thinking, sometimes dramatically so.One of the main forces at work is a complete lack of nature, which is surprisinglybeneficial for the brain. Studies have demonstrated, for instance, that hospital patientsrecover more quickly when they can see trees from their windows, and that women livingin public housing are better able to focus when their apartments overlook a lawn.Even these glimpses of nature improve brain performance, it seems, because they provide a mental break from the urban life.This research arrives just as humans cross an important milestone (里程碑). For thefirst time in history, the majority of people live in cities. Instead of inhabiting wide-openspaces, we’ recrowded into concrete jungles, surrounded by traffic and millions ofstrangers. In recent years, it ’becomes clear that such unnatural surroundings have important implications for our mental and physical health, and can powerfully alter howwe think.This research is also leading some scientists to dabble(涉及) in urban design, as they look for ways to make the city less damaging to the brain. The good news is thateven slight alterations, such as planting more trees in the inner city or creating urbanparks with a greater variety of plants, can significantly reduce the negative sideeffects of city life. The mind needs nature, and even a little bit can be a big help.72.Which of the following is the main idea of this passage?B. The city hurts your brain.A. The city inspires talented people.C. The city has many pleasures and benefits.D. The city seriously affects the natural balance.73. The word“ metropolis” in the first paragraph is closest in meaning to.A. citizenB. natureC. cityD. stress74.What is the factor mentioned in the third paragraph that helps the hospitalpatients recover more quickly?A. Nature.B. Better treatment.C. Experienced doctors.D. Good medicine.75. According to the passage, which of the following statements is TRUE?A. Different aspects of an urban environment, such as the crowded streets, can leadto an increase in self-control.B. Small changes in urban design cannot reduce the negative side effects of city life.C. For the first time in history, the earth e’urbanspopulthantionruralis.morD. A walk down a busy city street will improve brain performance.Section C BAFEDDirections : Read the following passage and choose the most suitable heading fromA— F for each paragraph. There is one extra heading which you do not need. (F=AB)A. Classroom participationB. Differences in American university educationC. Examination systemD. Competition among studentsE. Honest policy in students’ school workF. Students’ responsibility for learning76. ___________There is considerable variety in university classroom in the United States. Because ofdiverse teaching methods and non-standardized curricula, no two courses are the same. Undergraduate courses are considerably different from graduate courses. The classroom atmosphere in expensive, private universities may differ from that in community colleges which are free and open to everyone.77. ___________Participation in the classroom is not only accepted but also expected of the student inmany courses. Some professors base part of the final grade on the student ’orals participation. Although there are formal lectures during which the student has a passiverole (i.e., listening and taking notes), many courses are organized around classroom discussions, student questions, and informal lectures.78. ___________Many teachers believe that the responsibility for learning lies with the student. If a long reading assignment is given, instructor expects students to be familiar with the information in the reading even if they do not discuss it in class or give an examination. (Courses are not designed merely for students to pass exams.) The ideal student is considered to be one who is motivated to learn for the sake of learning, not the one interested only in getting high grades.79. ___________Ideally, the teacher-student relationship at universities is characterized by trust. The honor system, put forward by the teacher and the university demands that the studentbe honest in all areas of school work. Thus , cheating on tests, plagiarizing ( 剽窃 ) in written work, presenting others ’ ideas as original, and turning in homework completedby someone else are all prohibited.80. ___________Relationships between students in the classroom can be cooperative or competitive. International students should not hesitate to ask for help if it is needed. There are牛津上海版英语必修1单元测试卷.专业 .专注 .courses, however, where grades are calculated in relation to other student ’scores. Therefore,in classes where such a grading curve is used, students may be reluctant to share lecturenotes or information for fear that their own grades will suffer.Section DBreastfeeding for a month or longer appears to reduce a woman ’ s risk o diabetes ( 糖尿病 ) later in life, according to a new study. The breastfeeding and diabetes link has been reported in other studies, according to researcher Eleanor Schwarz. Yet,her study makes the link easier to believe. Her study is published in a journal of medicine inAmerica. Schwarz and her colleagues looked at data about breastfeeding practices. Theyevaluated data on 2,233 women from California. Of those, 405 were not mothers, 1,125 weremothers who breastfed for at least a month, and 703 were mothers who had never breastfed.They were 40 to 78 years old.According to Schwarz ’study, the risk of getting a diagnosis (诊疗 ) of Type 2 diabetesfor women who breastfed all their children for a month or longer was similarto that of women who had not given birth. But mothers who had never breastfed werenearly twice as likely to develop diabetes as women who had never given birth.Mothers who never breastfed were about 1.4 times as likely to develop diabetes aswomen who breastfed for one to three months, Schwarz found.While one month of breastfeeding appears to make a difference, Schwarz says,even longer is better.“ Previous studies have shown the longer the mom breastfeeds,the more benefit for her body.” Many experts recommend breastfeeding for six months and continuing for a year, she says.The diabetes-breastfeeding link is probably explained by belly fat. Mothers, whodon ’ t breastfeed, as they get older, may have more belly fat, as breastfeeding helps newmothers take off weight. “ Belly fat increases the risk of diabetes as you get older, says.The findi ng isn’ t surprising at all, says Kimberly Gregory. She often gives advice towomen who get diabetes occurring during pregnancy ( 怀胎 ) that they are at risk for latergetting Type 2 diabetes and suggests they breastfeed. The new findings will probably inspireGregory to add to the advice she gives moms-to-be about the benefits of breastfeeding. Sheoften focuses on the benefits to the baby.牛津上海版英语必修1单元测试卷.专业 .专注 .81.

After a few days, the king became kind only enough to give the joker the 18to choose how he would like to die. As usual, the joker replied, “If it’s the 19thing to you, my Lord, I’d like to 20old age.” Certainly in this case, a good sense of 21saved the man’s life.It’s 22for us as well.

I was the waitress who got to take his order and serve him his food.The customer was difficult. He was quite openly upset with how his food was prepared. He sent his order back twice. When it at last arrived to his liking, he needed a cup of coffee.At this point, I had stayed 45 minutes past closing time. I didn’t even want to sit down because I knew my knees would pain and it would hurt terribly to get back up. I knew he would probably not give a tip. However, I tried to give him good service.As he was finishing his burger, I was refilling his coffee and accidentally spilled (洒落) it on the table and his plate. Of course I said sorry at once and used a piece of cloth to clean the table. I had thought he would become angry. However, he took a piece of paper out and helped clean off the spilled coffee. He asked to speak to the manager, so I called my boss to come over to the table.Instead of complaining to my boss and asking us to make up for his meal, he simply said, “This young lady’s done a good job. You need to keep her around as long as you can!” After he paid his bill, he left and left a tip. The customer had offered a $15 tip for his $8 dinner.36. Why did the author say the customer was difficult?A. Because he could only give a small tip.B. Because he came to the restaurant very late.C. Because the author wanted to go home early.D. Because he was always dissatisfied with the food.37. We can learn from the third paragraph that .A. the author liked her work very muchB. the author’s knees were always in painC. the author was too tired at that timeD. the author seldom received tips38. What happened after the author spilled the coffee?A. The customer refused to pay his bill.B. The customer complained to the boss.C. The customer became angry at once.D. The customer offered the author help.39. Which of the following words can best describe the author’s feeling at last?A. Surprised and happy.B. Calm and confident.C. Nervous and sad.D. Worried and disappointed.40. Which of the following could be the best title for the passage?A. A waitress who was praised by a customerB. An unexpected tip from an unlikely customerC. An unlucky waitress who served a difficult customerD. A difficult customer who came to a restaurant very lateB19-year-old Danny Bowman once spent 10 hours a day taking selfies (自拍). Now the British teen is talking about the real dangers of selfie addiction (上瘾).His addiction started at age 15 and quickly went out of control, which made him want to kill himself because he couldn’t take the perfect selfie.“I always wanted to take the perfect selfie and when I realized I couldn’t, I wanted to die,” he tells Mirror of his 200-selfie-a-day addiction. “The only thing I cared about was having my phone with me so I could take a picture of myself at any time of the day.”“I lost my friends, my education, my health and almost my life,” Bowman says.At Bowman’s worst, he would cut class three times an hour to take a selfie, and at last he dropped out of school at age 16, when his health started to fail. “I only ate an apple and a bowl of ri ce a day in order to be thinner,” he says.He didn’t leave his house for six months because he always thought he was not handsome enough.“Danny’s case is unusual,” says Doctor David Veal. “But this is a serious problem. It usually makes people want to ki ll themselves or do other unusual things.”Bowman is believed to be Britain’s first case and now receives treatment to help him deal with his technology (技术) addiction. “Though the cases of technology addiction are rare now, I think this kind of thing can happen to anyone. For me it showed itself in selfies; it could be something different for someone else,” he says.41. What’s Danny Bowman worried about?A. His selfie addiction.B. His dropping out of school.C. His staying indoors too long.D. His dislike of study.42. What happened at Bowman’s worst?A. His schooling was badly influenced.B. He took his phone wherever he went.C. He had no interest in food.D. He lost most of his friends.43. Bowman stayed indoors for six months because ______.A. he wanted to take a good pictureB. he was shy with his classmatesC. he wanted to become healthyD. he was worried about his looks44. What does Dr. David Veal think of selfie addiction?A. It has no real dangers.B. It will disappear itself.C. It can cause serious problems.D. It can be easily controlled.45.
