Uboat.Aftergetting here,her large family worked hard to build a new life in America.They never had much money but were rich in love.One day,when I was about 5 or 6 years ol,dmy parents and brothers went on a trip.It was just me and Nanny in the house for the weekend.Nanny seemed so happy to be taking care of me all by herself.She made me a special breakfast that first morning.However,all I could do was complain about how the food was not how Mom always made it.Nanny quietly put down the plate and went into the living room.I followed a minute later and saw that she had tears in her eyes.It was the first time I had ever seen my strong and proud grandmother cry and I was the one who had caused it.I walked over to Nanny,climbed on her lap,and for the first time in my short life I did something else too.I apologized without being told to and asked Nanny to forgive me.She smiled,rubbed my head,and told me I was a good boy even though I didn’t feel like one then.That memory just like my

people happier than seriously ill ones?Not necessarily.In a study described in the Journal of Experimental Psychology,a group of people with endstage kidney (肾) failure were provided with electronic devices that required them to record their moods at various times throughout the day.For comparison,a group of healthy volunteers used the same devices.When researchers had studied the results,they found that the levels of happiness were about the same for the two groups.The researchers,led by Dr Jason Riis of Princeton when he was a graduate student at the University of Michigan,also found that the healthy people greatly overestimated (估计过高) how unhappy the sick ones would be.And the sick people overestimated how happy the healthy ones would be.For the study,49 kidney disease patients who were undergoing dialysis (透析) sections three times a week were given personal digital assistants,as 49 healthy volunteers were matched to the patients by age,race,education and sex.When the devices beeped,the subjects were asked to rate their mood on a 5point scale,with 2 defined as “very pleasant” and minus 2 defined as “very unpleasant”.On average,the kidney patients rated their mood as 0.70,while the healthy subjects rated it as 0.83.The participants were also asked to describe other emotions they might be feeling,including joy and anxiety,and to describe their levels of physical comfort.And sometimes they were aske,d “How do you feel about your life as a whole?”A better understandingof how well peopleare able to adapt to poor health,the researchers said,could help doctors and patients make wiser choices about their medical care.Earlier studies have also found that seriously ill patients described themselves as being happy.But these patients were not given a chance to answer questions about their mood privately and repeatedly over a period of time,Dr Riis said,and so it was unclear how accurate their responses were.5.What can be learnt from the study?A.The electronic devices used are digital assistants for dialysis.B.The levels of happiness are little affected by health condition.C.All the subjects are of the same age,race,sex and education.D.Both patients and healthy people overestimate their own happiness.6.In the research,the subjects’ ratings of their mood levels were________on average.A.vague B.negativeC.positive D.neutral7.One of Dr Riis’ concerns about the results of the earlier studies was whether________.A.it reflected what the patients really thoughtB.it revealed the patients’ privacyC.the questions for the patients were repeatedD.the assignment for all subjects was accurate8.The research was done in order to________.A.help patients adapt to poor healthB.learn patients’ average level of happinessC.find the distinction between the healthy and unhealthy people D.define the extent to which health condition affects happiness 课时作业(十七)Ⅰ.单项填空1.解析:考查交际用语。

手惰市安逸阳光实验学校课时作业37 Cloning Ⅰ.阅读理解(2015·山西忻州一中月考)Cooking food over a smoky fire is found everywhere in the world. Itis often difficult to find wood for the fire. People who do not have woodmust spend large amounts of money on cooking fuel. However, there is amuch easier way to cook food using energy from the sun. Solar cookers,or ovens, have been used for centuries. A Swiss scientist made the firstsolar oven in 1767. Today, people are using solar cookers in manycountries around the world. People use solar ovens to cook food and toheat drinking water to kill bacteria and other harmful organisms.There are three kinds of solar ovens. The first is a box cooker. Itis designed with a special wall that shines or reflects sunlight intothe box. Heat gets trapped under a piece of glass or plastic coveringthe top of the cooker. A box oven is effective for slow cooking of largeamounts of food.The second kind of solar oven is a panel(嵌板式) cooker. It includesseveral flat walls, or panels, which directly reflect the sun's lightonto the food. The food is inside a separate container of plastic or glass that traps heat energy. People can build panel cookers quickly and with very few supplies. They do not cost much. In Kenya, for example, panel cookers are being manufactured for just two dollars.The third kind of solar oven is a parabolic(抛物线的) cooker. It has rounded walls that aim sunlight directly into the bottom of the oven. Food cooks quickly in parabolic ovens. However, these cookers are hard to make. Th ey must be reaimed often to follow the sun. Parabolic cookers can also cause burns and eye injuries if they are not used correctly.You can make solar ovens from boxes or heavy paper. They will not catch fire. Paper burns at 232 degrees Celsius. A solar cooker never gets that hot. Solar ovens cook food at low temperatures over long periods of time. This permits people to leave food to cook while they do other things.To learn more about solar cooking, you can write to Solar Cookers International. The post al address is nineteennineteen TwentyFirst Street, Sacramento, California, ninefiveeightoneone, USA. Or you can visit the group's Internet Web site. The address is.1.How long is the first solar cookers invented?A.About 1767 year.B.More than 300 years.C.More than 250 years.D.Less than 250 years.2.In which of the following column could we find the passage? A.Development Report.B.Agricultural Report.C.Health Report.D.Education Report.3.Which of the following is TRUE?A.The first suncooker was made by a Swiss soldier. B.Parabolic cookers can be dangerous sometimes.C.Suncookers often get hotter than 232℃.D.It is more expensive to cook with a suncooker than on fire. 4.Which of the following could be the best title of the passage? A.Different Ways of CookingB.The History of the Solar CookersC.How to Choose Solar CookersD.Cooking Meals with the Sun for Fuel答案与解析1.D 细节理解题。

(20分)剃刀侠木桦清朝嘉庆年间,北京正阳门(俗称前门)外,已是相当繁华的集贸市场。
几十丈高的城门楼子,威严如皇帝老子,凝视着熙来攘往的人流。
这天,朗日晴空,集市正值繁华喧闹之时。
一匹枣红大马,上骑一员佩刀武官,后跟几个步行兵卒,像一股浪头把人流冲得七零八落。
门楼下老摊贩认得,这是乾清门蓝翎侍卫。
这些蓝翎宠儿每隔几日便会出宫耀武扬威找廉价。
这位蓝翎爷果然在一处最繁华的地点下马了。
小兵卒赶快接过马缰跟在后头,那蓝翎爷就摇着马鞭四处转悠。
他盯上几个剃头挑子,就踅过来,在一个空位前站住。
明显这家伙是要剃头或刮脸修胡子。
因此一概是白活儿。
一个年轻的剃头师傅赶忙躬身让位。
那蓝翎爷也不搭话,将马鞭丢在地上,一屁股坐在空木椅上。
谁知那木椅早已破朽,加之这蓝翎爷体肥身重,木椅“咔嚓”一声就散了架。
这家伙一个四仰八叉摔在地上。
这还了得!蓝翎爷火从天降,怒从胆生,抓起地上的马鞭,劈头盖脑就向小师傅猛抽起来,直抽得小师傅满脸淌血,爹一声妈一声叫着,他才给两个小卒扶到另一个剃头挑儿前。
那挑子一头火正旺,铜盆里的净水正冒热气。
挑儿前一个年过半百的瘦老头儿正在刀荡子上“哧哧”荡刀。
小卒就把蓝翎爷扶到木椅上坐好,督促老师傅抓紧干活儿。
到底是老马识途。
瘦老头儿就小心翼翼,轻手轻脚给蓝翎爷盘起辫子剃起来。
那半寸宽极好钢口的红木短把儿剃刀,被荡得吹毛立断,直把蓝翎爷辫子周边刮得油光锃亮,苍蝇落上都得打滑。
蓝翎爷给刮得懒洋洋,就有睡意,就有小卒子过来用背托着头。
老人就把刀板儿在睡脸上游动。
那剃刀在阳光下熠熠闪亮,那蓝翎爷就“呼噜呼噜”睡。
脸刮完,瘦老头儿就拿白毛巾去挑子一头热铜盆里蘸个热毛巾,用手边试凉热边把毛巾蒙到蓝翎爷脸上。
这是最后一道工序。
热巾上脸,蓝翎爷就醒了。
按规矩老师傅掀起毛巾盖住眼睛,轻松地在下巴和颈项处又找几刀,这才把热毛巾在胖脸上一擦,撤掉颈项上围的大毛巾,把蓝翎爷头一扶,小卒子就顺势把蓝翎爷扶起来。

课时作业17Ⅰ.阅读理解AAlong with the progress of reform and opening up, the Chinese film industry has also made remarkable achievements and economic growth. It has recorded social changes in the past decades through the medium of the film. The film market of China has been much better than that of North America, becoming the largest in the world during the first season of 2019.In the original stage of reform and opening up, old Chinese movies were rescreened and foreign movies dubbed (译制). Audiences' enthusiasm for movies was lighted up by both these practices. In 1979, the attendance of Chinese moviegoers reached a record high of 29.3 billion. However, televisions and other entertainment activities sprang up in the late 1980s and drew many audiences away from movies when the film market faced a danger.The employment of a socialist market economy in China in 1992 brought energy again to the film industry. With the introduction of free competition and reforms, it made an abundant recovery and experienced rapid growth. In the same period, China began to introduce overseas movies into the home market, especially those from Hollywood. Despite the argument that foreign movies occupy the space of homemade ones, Chinese movies with increasingly higher quality have gained a firm foothold in the local market with box offices setting several new records.The development of the Internet has added new energy to the Chinese film industry. In 2015, the powerful Internet companies, one called Tencent and another Alibada, developed their own film arm and began to adapt popular online stories for movies. With big data, more accurate marketing skills can target specific audiences to satisfy their personal preferences. Yet the development of online cinemas may pose threats to the survival of offline ones. Now the film industry is exploring more advanced film screening technologies to provide audiences with an improved movie experience.本文是一篇说明文。

与此直接相关的史实是()A.第一次世界大战B.“战时共产主义”政策的继续实施C.世界性经济危机D.高度集中计划经济体制的建立答案B解析国内战争平息后,苏俄继续实行“战时共产主义”政策,企图直接过渡到共产主义社会,这超越了社会生产力的发展水平,不利于社会经济的恢复发展,故选B项。
2.(2021·辽宁省高三新高考调研考试)1920年列宁说:“与那些先进的人民相比,俄国人民是糟糕的工人。
”英国学者理查德·韦南也认为:“事实上,对那些生产状况与芝加哥工厂相差悬殊的俄国工厂进行合理化改革本身是很浪漫的。
”这反映了当时()A.西方国家的劳动生产率高B.芝加哥是美国工业中心C.俄国的经济政策存在问题D.苏联工业化遇到了困境答案C解析依据时间、人物和经济发展水平信息判断,此时是苏俄战时共产主义政策时期,故C正确。

4.下表反映了1919年和1925年苏俄(联)农村每个成年人消费量的变化情况(单位:千克)。
此变化主要是由于()A.政府减轻了农民负担B.农业生产技术革新C.工业化建设全面开展D.新经济政策的实施答案D解析表格中成年人对粮食、肉和糖的消费量的增长是由于1921年新经济政策实施后,经济得到恢复和发展,保证并推动了农民对粮食等生活资料消费量的增长,故选D项。

手惰市安逸阳光实验学校课时作业19 Body languageⅠ.阅读理解(2015·质检Ⅰ)If you are sending a text, watching the TV or listening to the radio, you may want to stop and give this your full attention. Multitasking shrinks(萎缩) the brain, research suggests.A study found that men and women who frequently used several types of technology at the same time had less grey matter in a key part of the brain.University of Sussex researchers said:“simultaneously using mobile phones, laptops and other media devices could be changing the structure of our brains.” Worryingly, the part of the brain that shrinks is involved in processing emotion.The finding follows research which has linked multitasking with a shortened attention span (持续时间),depression, anxiety and lower grades at school.The researchers began by asking 75 healthy men and women how often they divided their attention between different types of technology. This could mean sending a text message while listening to music and checking email, or speaking on the phone while watching TV and surfing the web. The volunteers were then given brain scans which showed they had less grey matter in a region called the anterior cingulate cortex(ACC).The study, published in the journal PLOS ONE, is the first to make a link between multitasking and the structure of the brain.Researcher Kep Kee Loh said:“Media multitasking is becoming more prevalent in our lives today and there is increasing concern about its impacts on our cognition and socialemotional wellbeing.” “He added that more research is needed to prove that multitasking shrinks the brain. This is because it is also possible that people with less grey matter in the ACC are more drawn to using lots of gadgets simultaneously.” Experts have also warned of the harmful impact technology can have on our memory and attention span. The University of California team commissioned a survey of more than 18,000 people aged between 18 and 99 and found 20 percent had problems with memory. Researchers were taken aback by the 14 percent of 18 to 39yearolds who also worried about their memories.Multitasking with gadgets may shorten attention span, making itharder to focus and form memories, the researchers said, adding that youngsters may be particularly affected by stress.1.What's the main idea of this passage?A.Multitasking shortens attention span.B.Multitasking makes your brain smaller.C.Multitasking has harmful effects on our memory.D.Multitasking is becoming more and more popular.2.What does the underlined word “simultaneously” (in Par agraph 3) mean?A.frequentlyB.now and thenC.in the meantime D.for a long time3.What's the opinion of Kep Kee Loh on media multitasking?A.people with less grey matter are more willing to use gadgets lots.B.Whether multitasking shrinks the brain remains to be studied further.C.Multitasking with gadgets makes it harder to focus and form memories.D.Media multitasking affects on our cognition and socialemotional wellbeing.4.Researchers believe that multitasking may cause people to be ________.A.attentive B.addictedC.absentminded D.intelligent答案与解析1.B 主旨大意题。

read storybooks to preschool children.But a new study suggests that calling attention to the words and letters on the page may lead to better readers.The twoyear study compared children who were read in this way in class with children who were not.Those whose teachers most often discussed the print showed clearly higher skills in reading,spelling and understanding.These results were found one year and even two years later.Shayne Piasta,an assistant professor of teaching and learning at Ohio State University,was an author of the study.She says most preschool teachers would find this method manageable and would need only a small change in the way they teach.They already read storybooks in class.The only difference would be increased attention to the printed text.“If you get children to pay attention to letters and words,it makes sense that they will do better at word recog nition and spelling.” But she says research suggests that very few parents and teachers do this in a systematic way.More than 300 children aged four and five were observed in classrooms.They came from poor families and were below average in their language skills.For thirty weeks,the children took part in a program called Project STAR—Sit Together and Read.The project is based at Ohio State.It tests the shortterm and longterm results of reading regularly to preschool children in their classrooms.There are different ways that adults can talk to children about print.They can point to a letter and discuss it,and even trace the shape with a finger.They can point out a word and discuss the meaning of the print or how the words tell the story.And they can talk about the organization of the print—for instance,showing how words are written left to right in English.1.What do we know about the ways preschool children are usually taught?A.Preference is given to the shape of letters and the organization of the print.B.More attention is paid to the pictures,with words and letters being ignored.C.The focus of the teaching is on bringing them up to be good readers.D.Equal attention is paid to the texts and the pictures.2.What does Shayne Piasta suggest preschool teachers should do in cl ass?A.Teach children how to draw pictures to get an idea of what they mean.B.Adopt different methods according to the students’ difference in reading skills.C.Change the way they teach and pay more attention to words and letters.D.Read storybooks to children rather than explain the meaning of the pictures.3.Which of the following is TRUE about the study on language skills of preschool children?A.Many teachers want to change their way of teaching preschool children.B.Attention on the pictures has made the children uninterested in reading.C.Teachers are often prevented from taking different approaches to language teaching.D.Project STAR aims to research into the results of reading books to preschool children in the classroom.4.Which section of a magazine does the passage probably come from?A.Fashion. B.Economy.C.Education. D.Entertainment.Ⅲ.任务型读写(2013·安徽省六校教育研究会高三联考)Have you ever wondered:what drives successful people?Take a look around and talk to your friends and seniors who are very successful,you will see all of them have adopted certain values which have proved vital for their success.It is evident that successful people take initiative (主动性).When they find something needs to be done,they just do it instead of waiting.They believe that responsibility is taken,not given.They weigh immediately what has to be done and then do it with pleasure,thus strengthening their reputation.Successful people are enthusiastic about the things they do,and they believe in what they are doing.They are motivated by their own satisfaction and the joy they get from doing their work.They work hard even when no one is watching and they throw themselves into their work.They do not fear failure.Failures and disappointments in life are unavoidable.It is failure that teaches us much more than success.Successful people pick themselves up after a fall and try again with more determination and commitment and learn from each failure.They associate with those they can learn from and enjoy the company of those who appreciate their achievement.Having good IQ often gets a person what he wants but it’s really the EQ that keeps him there and helps him enjoy a high reputation.Successful people are polite to everyone and treat others with respect.By giving respect to others,they commandrespect for themselves.Another important quality of successful people is that they never complain.It’s better to praise others and win favor with them.So instead of complaining about a situation,successful people always try to solve it.To put it shortly,take initiative and be enthusiastic about them.Do not be afraid to fail,but get up and start again.When you do so,success will be just around the corner.Title:What Makes People Successful?课时作业(十)Ⅰ.单项填空1.解析:考查交际用语。
北师大安徽用英语一轮复习指导课时作业34 nit 1 B卷 含解析
课时作业34 Unit 17 B卷一、阅读理解AA man living absolutely alone in a desert or forest is free from other people,but he is not absolutely free.His freedom is limited in several ways.Firstly,by the things around him,such as wild animals or cliffs.Secondly,by his own needs:he must have sleep,water,food and shelter from extreme heat or stly,by his own nature as a man:disease may attack him,and death will certainly come to him sooner or later.On the other hand,when men become organized into very large groups and civilization develops,it is possible to get freedom from hunger,thirst,cold,heat,and many diseases,so that each person can live a happier life than he could if he were living alone;but such a society cannot work successfully unless the freedom of each human being is to some extent limited so that he is kept from hurting others.I am not free to kill others,nor to steal someone else’s property,nor to act in a way that does wrong against the moral sense of the society in which we live.I have to limit my own freedom myself so that others will not limit it too much.I agree to respect the rights of others,and in return they agree to respect mine.The advantages of such an agreement are great.One can become a doctor knowing that others will grow food,make clothes and build a house for him,in return for the work he does to keep them healthy.If each man had to grow his own food,make his own clothes,build his own house and learn to be his own doctor,he would find it impossible to do any one of these jobs really well.By working together,we make it possible for society to provide us all with food,clothes,shelter and medical care,while leaving each of us with as much freedom as it can.1.A man living alone in a desert or forest ______.A.is absolutely free B.feels happyC.has limited freedom D.enjoys no freedom2.According to the writer,he limits his freedom because ______.A.hunger,thirst and disease limit himB.others won’t limit theirsC.the moral sense of the society limits himD.others will respect him3.The author suggests that when men live together ______.A.they feel safer and easierB.they are not freeC.they must build sheltersD.they can get protection4.This text is written mainly to show that ______.A.one can have all his freedom by living on his ownB.one has limited freedom just because of his own natureC.one must fight for his freedom if he’s free from other peopleD.one will have much freedom by working together with othersBIt’s true that littered cigarette butts(烟蒂)are an annoying thing for the public,and not just for the appearance reasons.The filters(过滤嘴)on cigarettes—four fifths of all cigarettes have them—are made of a form of plastic that is very slow to break down in the environment.A typical cigarette butt can take from 18 months to 10 years to decompose,depending on environmental conditions.Besides the plastic,these filters—which are on cigarettes in the first place to absorb pollutants to prevent them from going into the lungs—contain poisons.Thus when smokers throw away their butts improperly—out of car windows or onto the sidewalks—they are essentially throwing these poisonous substances into the environment.While any individual thrown-away cigarette butts may be small,the butts add up to a huge problem.Some 5.5 trillion cigarettes are consumed worldwide each year.Cigarette butts make up as much as one-third of all litter nationwide when measured by the number of discarded items,not the total volume.While the tobacco industry may have its hands full just trying to stay afloat in the maelstrom(旋涡)of ongoing bad publicity,critics say it should be doing more to prevent butt litter.“Just as beverage manufacturers contribute to anti-littering campaigns,and have invested in public education on litter issues,so should thetobacco industry,”says Kathleen Register,a researcher.Register suggests putting anti-littering messages on all cigarette packaging and advertisements,distributing small,free portable ashtrays(烟灰缸),and placing and maintaining outdoor ashtrays in areas where smokers gather.She also suggests putting an extra tax on cigarette sales,with the money going toward anti-littering education and paying the costs of cleaning up butts.“By taxing smokers for such efforts,some of the cost of cleaning up cigarette butts will shift onto them,”she says.One way or another,smokers must learn that the earth is not one giant ashtray.5.The underlined word“decompose”in Paragraph 1 probably means“______”.A.burn away B.break upC.go out D.die down6.Littering cigarette butts around is harmful because______.A.they lead to global warmingB.they waste plasticC.they contain poisonsD.they cause lung cancer7.Which of the following will force smokers to contribute to the environment,according to the text?A.Having them pay an extra tax on cigarettes.B.Having anti-litter messages appear on cigarette packaging.C.Forbidding cigarette advertising in public.D.Forcing them to take ashtrays with them.8.The main topic of the text is______.A.the danger of cigarette smokersB.the environmental effects of discarded cigarettesC.the disease smokers sufferedD.the chemical makeup of cigarette butts二、任务型读写阅读下面短文,根据所读内容在表格中的空白处填入恰当的单词。
课时作业17:氧化还原反应的计算及方程式的配平
第5讲氧化还原反应的计算及方程式的配平一、选择题(每小题只有一个选项符合题意)1.某碘盐(含KIO3)溶解于水,滴加KOH溶液使之显碱性,若通入氯气可以生成K3H2IO6,关于该反应的说法错误的是()A.碘盐中碘元素被氧化B.Cl2的氧化性强于IO-3C.氧化剂与还原剂的物质的量之比为1∶2D.转移1 mol电子时,有0.5 mol K3H2IO6生成答案C解析向碘酸钾(KIO3)的碱性溶液中通入氯气,可以得到K3H2IO6,反应中I元素的化合价由+5价升高为+7价,Cl元素的化合价由0降低为-1价,反应的离子方程式为IO-3+Cl2+4OH-===H2IO3-6+2Cl-+H2O。
I元素的化合价升高,则在该反应中碘元素被氧化,故A正确;该反应中IO-3作还原剂,Cl2作氧化剂,Cl2的氧化性强于IO-3,故B正确;根据方程式可知,IO-3作还原剂,Cl2作氧化剂,氧化剂与还原剂的物质的量之比为1∶1,故C错误;反应中生成 1 mol K3H2IO6转移1 mol×(7-5)=2 mol电子,则反应中转移1 mol电子时,有0.5 mol K3H2IO6生成,故D正确。
2.衣服上不小心沾到了蓝色墨水,可以先涂上酸性高锰酸钾溶液,即可除去蓝墨水中的鞣酸亚铁,再用乙二酸的稀溶液擦洗,可以迅速除去过量的KMnO4,其反应的离子方程式为MnO-4+H2C2O4+H+―→CO2↑+Mn2++H2O(未配平)。
下列有关叙述不正确的是()A.每转移2 mol电子,就有1 mol乙二酸被还原B.氧化剂和还原剂的化学计量数之比是2∶5C.鞣酸亚铁和乙二酸都具有还原性D.蓝墨水与红墨水混用易因胶体聚沉而导致书写不畅答案A解析乙二酸中碳元素的化合价为+3价,生成物二氧化碳中碳元素的化合价为+4价,化合价升高,是被氧化而不是被还原,故A错误;根据配平的离子方程式可知,氧化剂是高锰酸根,还原剂是乙二酸,氧化剂和还原剂的化学计量数之比是2∶5,故B 正确;酸性高锰酸钾溶液可除去蓝墨水中的鞣酸亚铁,再用乙二酸的稀溶液擦洗,酸性高锰酸钾溶液具有强氧化性,鞣酸亚铁和乙二酸都具有还原性,故C 正确;蓝墨水是一种胶体,蓝墨水与红墨水混用,易因胶体聚沉而导致书写不畅,故D 正确。

came to this country with her family on a tiny ship during World War Ⅰ when she was only 8 years old.During the trip she survived stormy seas,little food,and an attack by a German Ub oat.After getting here,her large family worked hard to build a new life in America.They never had much money but were rich in love.One day,when I was about 5 or 6 years old,my parents and brothers went on a trip.It was just me and Nanny in the house for the weekend.Nanny seemed so happy to be taking care of me all by herself.She made me a special breakfast that first morning.However,all I could do was complain about how the food was not how Mom always made it.Nanny quietly put down the plate and went into the living room.I followed a minute later and saw that she had tears in her eyes.It was the first time I had ever seen my strong and proud grandmother cry and I was the one who had caused it.I walked over to Nanny,climbed on her lap,and for the first time in my short life I did something else too.I apologized without being told to and asked Nanny to forgive me.She smiled,rubbed my head,and told me I was a good boy even though I didn’t feel like one then.That memory just like my Nanny’s love will stay in my heart forever.It is a sign of both strength and wisdom.Asking for forgiveness helps us to learn,to grow,and to love.1.Nanny’s family immigrated to America mainly because________.A.they suffered starvation in their homelandB.they wanted to start a rich life in the new landC.they tried to get away from the terrible climateD.their country was in war and they needed peace2.The boy complained to Nanny that the food________.A.wasn’t cooked the way his Mom didB.was served a bit later than usualC.was prepared in a special wayD.was just to his parents’ taste3.When seeing Nanny crying in the living room,the author felt________.A.surprised B.ashamedC.shocked D.annoyed4.The author mainly wants to tell us that________.A.forgiveness can be beneficial to people asking for itB.hardships can make children more indifferentC.grandparents are more tolerant than their grandchildrenD.family ties can sometimes be misusedB(2013·安徽省皖南八校高三第三次联考)Are healthy people happier than seriously ill ones?Not necessarily.In a study described in the Journal of Experimental Psychology,a group of people with endstage kidney (肾) failure were provided with electronic devices that required them to record their moods at various times throughout the day.For comparison,a group of healthy volunteers used the same devices.When researchers had studied the results,they found that the levels of happiness were about the same for the two groups.The researchers,led by Dr Jason Riis of Princeton when he was a graduate student at the University of Michigan,also found that the healthy people greatly overestimated (估计过高) how unhappy the sick ones would be.And the sick people overestimated how happy the healthy ones would be.For the study,49 kidney disease patients who were undergoing dialysis (透析) sections three times a week were given personal digital assistants,as 49 healthy volunteers were matched to the patients by age,race,education and sex.When the devices beeped,the subjects were asked to rate their mood on a 5po int scale,with 2 defined as “very pleasant” and minus 2 defined as “very unpleasant”.On average,the kidney patients rated their mood as 0.70,while the healthy subjects rated it as 0.83.The participants were also asked to describe other emotions they might be feeling,including joy and anxiety,and to describe their levels of physical comfort.And sometimes they were asked,“How do you feel about your life as a whole?”A better understanding of how well people are able to adapt to poor health,the researchers said,could help doctors and patients make wiser choices about their medical care.Earlier studies have also found that seriously ill patients described themselves as being happy.But these patients were not given a chance to answer questions about their mood privately and repeatedly over a period of time,Dr Riis said,and so it was unclear how accurate their responses were.5.What can be learnt from the study?A.The electronic devices used are digital assistants for dialysis.B.The levels of happiness are little affected by health condition.C.All the subjects are of the same age,race,sex and education.D.Both patients and healthy people overestimate their own happiness.6.In the research,the subjects’ ratings of their mood levels were________on average.A.vague B.negativeC.positive D.neutral7.One of Dr Riis’ concerns about the results of the earlier studies was whether________.A.it reflected what the patients really thoughtB.it revealed the patients’ privacyC.the questions for the patients were repeatedD.the assignment for all subjects was accurate8.The research was done in order to________.A.help patients adapt to poor healthB.learn patients’ average level of happinessC.find the distinction between the
