categorized (把……归类) as “honor” help you create this life of good feelings.Here’s an example to show how honorable actions create happiness.Say a store clerk fails to charge us for an item.If we keep silent,and profit from the clerk’s mistake,we woulddrive home with a sense of sneaky (暗中的) ter we might tell our family or friends about our good fortune.On the other hand,if we tell the clerk about the uncharged item,the clerk would be grateful and thank us for our honesty.We would leave the store with a quiet sense of honor that we might never share with another soul.Then,what is it to do with our sense of happiness?In the first case,where we don’t tell the clerk,a couple of things would happen.Deep down inside we would know ourselves as a type of thief.In the process,we would lose some peace of mind and self-respect.We would also demonstrate that we cannot be trusted,since we advertise our dishonor by telling our family and friends.We damage our own reputations by telling others.In contrast,bringing_the_error_to_the__clerk’s__attention causes different things to happen.Immediately the clerk knows us to be honorable.Upon leaving the store,we feel honorable and our self-respect is increased.Whenever we take honorable actions we gain the deep internal rewards of goodness and a sense of nobility.There is a beautiful positive cycle that is created by living a life of honorable actions.Honorable thoughts lead to honorable actions.Honorable actions lead us to a happier existence.And it’s easy to think and act honorably again when we’re happy.While the positive cycle can be difficult to start,once it’s started,it’s easy to continue.Keeping on doing good deeds brings us peace of mind,which is important for our happiness.1.According to the passage,the positive action in the example contributes to our________.A.self-respect B.financial rewardsC.advertising ability D.friendly relationship2.The author thinks that keeping silent about the uncharged item is equal to________.A.lying B.stealingC.cheating D.advertising3.The underlined phrase “bringing the error to the clerk’s attention”means________.A.telling the truth to the clerkB.offering advice to the clerkC.asking the clerk to be more attentiveD.reminding the clerk of the charged items4.How will we feel if we let the clerk know the mistake?A.We’ll be very excited.B.We’ll feel unfortunate.C.We’ll have a sense of honor.D.We’ll feel sorry for the clerk.5.Which of the following can be the best title of this passage?A.How to Live TruthfullyB.Importance of PeacefulnessC.Ways of Gaining Self-respectD.Happiness through Honorable ActionsB(2021·济宁高考模拟)A euphemism (from the Greek words eu—well and pheme—speak) is a word or expression that is used when people want to find a polite or less direct way of talking about difficult or embarrassing topics like death or the bodily functions.Most people,for example,would find it very difficult to say in plain language that they have arranged for their sick old dog to be killed.They would soften the pain by saying:We had Ruby put down or We had Ruby put to sleep.Many people prefer to call someone plain than ugly,or cuddly rather than fat.Euphemisms are an important part of every language,but it seems that English has an ever-growing number of them.The non-native speaker not only has to make sense of the euphemisms he hears,he also has to learn which euphemisms are appropriate in any particular situation.He might be aware that his American friend needs to use the toilet when she asks where the bathroom (or restroom,or comfort station) is,but he is less likely to guess that his English friend has the same need when he says he has to see a man about a dog.He might have learned,for example,that in the family way is a euphemism for pregnant.If,however,he says to his boss,“Congratulations!I hear your wife is in the family way,” he would be using an expression that is too familiar for the circumstances.Schools are full of euphemisms.At Frankfurt International School,for example,the special lessons given to students who are having difficulties in their school subjects are called Study Center (in the middle school) and Academic Workshop (in the high school).Teachers rightly do not want to upset students or parents by being too frank or straightforward,and usually choose a softer word or expression to convey the same message.6.According to the passage,people use euphemisms in order to________.A.make themselves understoodB.avoid embarrassmentC.to sound straightforwardD.attract attention7.A person who is described as plain and cuddly is in fact________.A.tall and handsome B.pretty and slimC.ugly but tall D.ugly and fat8.When an English lady says she has to see a man about a dog,she might want to________.A.have her old dog killed B.see an ugly friendC.go to the toilet D.see a pregnant woman9.The main purpose of Paragraph 2 is to________.A.stress that euphemisms are an important part of every languageB.inform readers that English has an ever-growing number of euphemismsC.suggest non-native speakers use euphemisms as often as possibleD.warn English learners to be careful about the meaning and use of euphemisms10.At Frankfurt International School,the students who receive lessons in Study Center________.A.have poor grades in the subjectsB.do well in schoolC.work hard at their lessonsD.prefer to learn more课时作业(二)Ⅰ.单项填空1.解析:考查情景交际。

But most ly, they are always there for you —whether it’s in person or 36 late night phone calls — in good times and 37 . But as the years pass, it becomes increasingly 38 to see each other, to make new memories. 39 , my high school friends and I promised long ago not to let this happen. We promised to have reunions.A few months ago, we met up for a two-day 40 in the American Southwest. We grew up together in Maine and have said for years that we should have a(n) 41 event, yet it’s often put off or 42 due to schedule conflicts. Not this year.The weekend 43 long talks by the pool, wonderful meals, and a hike that brought the entire group to 44 . Not tears of sadness or anger, but an outpouring of emotion over the complete wonderment that we can be this close —twelve years after graduation —with such physical 45 between us. It’s heartbreaking that we can’t spend our days together in the same neighborhood, walking the same streets, reading the same newspaper at the same coffee shop. But that’s 46 . Grown-up life.Most 47 is the group’s a daptability to one another. The time we spend 48 is non-existent. No need to get reacquainted (重新熟悉), we jump back in the saddle (车座) and it’s as comfortable as ever. Old friends — friends with an ever-present 49 of support and sisterhood, friends that know each other innately (天生地) — are hard to come by and yet we remain as 50 today as we were, years ago, giggling in the back row of Mr. McKechnie’s 9th grade math class.Life today, 51 , is no math class. Our world is full of 52 , full of fear. Y et it 53 me — now, more than ever — how important it is that we stay 54 .

The traffic was terribly affected.BOne winter evening, a storekeeper was going to close up his shop. Suddenly he saw Seth, a lazy, good-for-nothing fellow grab a pound of fresh butter and hid it in his hat. No sooner had the storekeeper seen the act than he hit upon exactly the right revenge (报复) . He would punish the thief, and satisfy his own appetite for fun.Seth had his hat on his head, and the butter in his hat. He was anxious to leave. However, the rightful owner of the butter offered him a cup of hot drink, took him by the shoulders and planted him in a seat close to the stove. The grocer stuffed in the stove as many sticks of wood as he could possibly fit inside.Seth already could feel the butter settling down closer to his hair, so he jumped up, declaring that he must go.“Sit down; don’ t be in such a hurry,” replied the grocer, pushing him back into the chair again.Streak after streak of the butter came pouring from under the poor man’s hat. The fun-loving grocer kept on stuffing wood into the stove. Then, as if surprised, he remarked, “You seem to be perspiring (排汗) as if you were warm! Let me put your hat away for you.”“No!” exclaimed poor Seth at last, unable to stand it a moment longer. “No, I must go; let me out.”A greasy (油腻的) waterfall of butter was now pouring down the poor man’s face and neck, soaking(浸泡) into his clothes, and trickling (滴) down his body into his boots. He was bathed in oil from head to toe.Just as his victim darted out the door, the grocer said, “I reckon (估计) the fun I’ve had out of you is worth the money, so I shan’t charge you for that pound of butter in your hat.”60. Why did Seth put the butter in his hat?A. Because he just wanted to play a trick on the grocer.B. Because he had nowhere to put the butter but in the hat.C.

The grocer offered Seth a cup of hot drink.B. The grocer overcharged Seth for the butter.C. The grocer forced Seth to take a seat near the stove.D. The gr ocer offered to take off Seth’s hat.62. What is the best title of the passage?A. Great funB. A fun-loving grocerC. The right revengeD. A foolish customerCExpensive and new gloves allow chatterboxes (话匣子) to take the term “handsfree” to a new level—by talking into them as they make a call. The gloves are known as “Talk to the Hand” and cost £1,000 a pair. They fixed a speaker unit into the thumb and a microphone into the little finger that can be connected to any mobile handset using Bluetooth.Artist Sean Miles designed the new gloves that double as a phone in part of his project that shows the possibilities of gadget (小玩意) recycling. He uses outdated gloves and combines them with parts from mobile handsets recycled through O2, which commissioned (承担) the project. Mobile phone users will be able to keep their hands warm while they chat without taking their phones out of their pockets or handbags.Mr. Miles designed two pairs of the new gloves — one in pink and the other in brown and yellow. They will appear in an exhibition this July and visitors will be able to win the gloves. If demand is high, they will then be produced on a larger scale(范围). O2 Recycle, which backed the project, estimates that there are already 70 million unused mobile handsets in the UK. The service pays up to £260 to those who recycle gadgets including phones, handheld consoles (操纵台), MP3 players and digital cameras.Designer Sean Miles hopes his work will get people thinking about recycling. The 41-year-old said, “I hope that my ‘Talk to the Hand’ project will get people to think again about the waste created by not recycling gadgets. If a few more people recycle their gadgets rather than send them to trash, I think this project will have fulfilled its aim.”Bill Eyres, head of O2 Recycle, urges people to recycle their phone responsibly. He said, “There’s a pressing need for all of us to look at outdated handsets, and a ll the gadgets that we move on from or upgrade each year. Whether they are consoles or cameras, we should think of them as a resource that we need to recycle responsibly rather than throw them away.”63. The underlined word “O2” in Paragraph 2 is probably the name of ______.A. an artistB. a companyC. a mobileD. an exhibition64. Consumers can buy the “Talk to the Hand” gloves ______.A. in the exhibitionB. from Mr MilesC. when they are mass-producedD. after they recycle the gadgets65. The purpose of the project is to _______.A. promote the technology of ITB. enable people to talk to their handsC. raise people’s awareness of recyclingD.attract visitors’ attention in the exhibition66. What is the passage mainly about?A. New mobiles which are fashionable.B. Outdated handsets which are upgraded.C. Outdated gadgets which can be used for recycling.D. New gloves which can be used for making phone calls.DLast year, CCTV journalists approached pedestrians (行人) with their cameras, held a microphone to their mouth and asked a simple question, “Are you happy?”The question has caught many interviewees off guard. Even Mo Yan, who just won a Nobel Prize, responded by saying, “I don’t know”.While the question has become a buzz phrase and the Internet plays host to heated discussions, we ask: What exactly is happiness? And how do you measure it?In the 1776 US Declaration of Independence, Thomas J efferson set in writing the people’s unalienable right to “Life, Liberty and the Pursuit of Happiness”. 235 years on, Wen Jiabao told the nation, “Everything we do is aimed at letting people live more happily.” At National People’s Congress, officials agreed that increasing happiness would be a top target for the 12th five-year plan.US psychologist Ed Diener, author of Happiness: Unlocking the Mysteries of Psychological Wealth, describes happiness as “a combination of life satisfaction and having more posi tive than negative emotions” according to US broadcasting network PBS. This may sound straightforward enough, but it still doesn’t explain what determines people’s happiness.Many argue that happiness is elusive and that there is no single source. It also means different things to different people. For some, happiness can be as simple as having enough cash.Researchers believe happiness can be separated into two types: daily experiences of hedonic (享乐的) well-being; and evaluative well-being, the way people think about their lives as a whole. The former refers to the quality of living, whereas the latter is about overall happiness, including life goals and achievements. Happiness can cross both dimensions (范围).Li Jun, a psychologist and mental therapy practi tioner at a Beijing clinic, says, “Happiness can mean both the most basic human satisfaction or the highest level of spiritual pursuit. It’s a simple yet profound topic.”Chen Shangyuan, 21, a junior English major at Nanjing University of Aeronautics and A stronautics, said his idea of happiness always evolves. “At present it relates to how productive I am in a day,” he said. “It might be linked to job security or leisure time after I graduate.”Then there is the question of measuring happiness. Does it depend on how many friends we have, or whether we own the latest smart phone? Is it even quantifiable?Economists are trying to measure happiness in people’s lives. Since 1972, Bhutan’s GDP measurement has been replaced by a Gross National Happiness index. It is calculated according to the peoples’ sense of being well-governed, their relationship with the environment, their satisfaction with economic development, and their sense of national belonging.In 2009, US economist Joseph Stiglitz proposed “to shift (转移) emphasis from measuring economic production to measuring people’s well-being”. But is well-being more easily measured?67. From what Thomas Jefferson and Wen Jiabao mentioned in the passage, we know ________.A. people’s happiness is determined by grea t peopleB. people’s happiness is an important target for the development of a countryC. people in all countries have the right to ask the government for a happy lifeD. people both in China and America are living a happy life68. According to the passage, the writer may most likely agree that ________.A. CCTV journalists are concerned about people’s happiness out of sympathyB. the question has led to heated discussions about who are the happiest people in ChinaC. Bhutan’s new index shows that people there are the happiest in the worldD. it is not easy for us to decide what determines people’s happiness69.What does the underlined word “elusive” in the sixth paragraph mean?A. availableB. easy to getC. hard to describeD. unimaginable70. The best title of the passage is ________.A. Are you happy?B. The Measurement of HappinessC. GDP and HappinessD.
