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

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。

Americans use many expressions with the word “dog”. People in the United States love their dogs and treat them well.1.However, dogs without owners to care for them lead a different kind of life. The expression, to lead a dog's life, describes a person who has an unhappy existence.Some people say we live in a dog-eat-dog world.2.They say that to be successful, a person has to work like a dog. This means they have to work very, very hard. Such hard work can make people dog-tired. And, the situation would be even worse if they became sick as a dog.3.This means that every person enjoys a successful period during his or her life. To be successful, people often have to learn new skills. Yet, some people say that you can never teach an old dog new tricks. They believe that older people do not like to learn new things and will not change the way they do things.4.People who are unkind or uncaring can be described as meaner than a junkyard dog. Junkyard dogs live in places where people throw away things they do not want. Mean dogs are often used to guard this property. They bark or attack people who try to enter the property. However, sometimes a person who appears to be mean and threatening is really not so bad. We say his bark is worse than his bite.Dog expressions are also used to describe the weather. The dog days of summer are the hottest days of the year. A rainstorm may cool the weather. But we do not want it to rain too hard.5..A. Still, people say every dog has its day.B. We do not want it to rain cats and dogs.C. Some people are compared to dogs in bad ways.D. Dogs are their best friends and they are loyal to people.E. There are many other expressions waiting for you to explore.F. That means many people are competing for the same things, like good jobs.G.

2013高考英语二轮(阅读理解)25分钟限时训练(2)及答案

2013高考英语二轮（阅读理解）25分钟限时训练（2）及答案阅读理解A 篇IS IT TIME TO GET MP3?Your computer has been playing music for years, one CD at a time. Now hundreds of songs can be stored in your PC (personal computer) if they’re in the MP3 format.What is it?MP3 compresses music into small computer friendly files. You access MP3 music several ways : Mus ic can be downloaded from websites that have converted vast music libraries into MP3. Or you can prerecord CDs into your PC and convert songs in minutes into MP3. Once MP3 music is on your PC’s hard drive, you can play it through your computer’s speakers, “burn” it onto blank CDs or exchange MP3 files with friends using E-mail.How much?Software needed to play and convert MP3 music is often free. It comes preinstalled on most new computers or can be downloaded from many websites, including MP3. com. Some MP3 sites are free. Just type “MP3 sites” into any search engine. The popular MP3 players start at around $50and can hold hundreds of songs. A blank CD on which you can record music costs about a dollar. AdvantagesMP3 turns your home PC into a tape recorder. Tiny MP3 players are the size of a card, making it easy to take hundreds of songs with you.DisadvantagesYou may find that music at many sites is limited. And some only allow you to listen rather than download offerings. Others let you d ownload music that then can’t be copied to MP3 players. Anda growing number of new CDs make it impossible to copy songs to a computer.46. How can you get MP3 music?A. By turning your home PC into a tape recorderB. By taking your own music or songs with youC. By copying songs to a PC through the speakers.D. By downloading from websites which have converted music libraries into MP3.47. Which is NOT true to the passage?A. Software needed to play and convert MP3 music is often free of charge.B. MP3 music can be with friends by e-mail.C. MP3 music ca n be downloaded for free at any site.D. A greater number of new CDs make it possible to copy songs to a computer.48.The underlined word “burn” probably means_____.A. fireB. changeC. downloadD. play49. How much will you pay for a MP3 player?A. Free of charge.B. Free downloading.C. At least fifty dollars.D. About a dollar.B篇Toky o: The world’s oldest man, retired Japanese silkworm breeder Yukichi Chuganji, died in his home at the age of 114, on Monday. Family m embers found him dead on his mattress. Born on March 23, 1889, Chuganji worked as a silkworm breeder and bank employee after leaving school.He also served as a community welfare(福利) officer. He had been in god health, talking daily with his family members.Washington: Every American dislikes people who talk on cell phones while driving, even those who do that kind of act. In the State of New Jersey, 84 percent of 968 cell phone owners said in recent telephone survey that they would support a state ban(禁令) on the use of cell phones while driving. However, 42 percent of cell phone owners also said t hey used the devices “very often” or “sometimes” while driving. Although most agree that the banning is good, only 38 percent believed such a ban would be easy to enforce(实施).New York: A woman in the US who was being attacked by a dog said she was saved from further harm when her 13-year-old daughter distracted the dog by screaming “You want a piece of me?” and kicked it repeatedly in the head. Jane Howell said she and her daughter, Elizabeth, were taking a walk around the n eighborhood on Saturday evening when they came across he big dog, unchained.50. The main idea of the second news is _____.A. most Americans don’t like cell phoneB. a ban on the use of cell ph ones has been madeC. few people use cell phones while drivingD. using cell pho nes while driving will be banned because most Americans don’t like it51. The woman in the US ____.A. was not harmed by the dogB. raised the dog, which attacked her laterC. was protected from being seriously hurt by her daughterD. had escaped when her daughter was kicking the dog52. From the news we can infer ____.A. Chuganji was living alone when he diedB. the woman’s 13-year-old daughter was very braveC. cell phones are not g od devicesD. it’s easy to enforce the ban n th e use of cell phones while driving参考答案46-52 DCBC DCB********************************************************结束HIt was an early September day, cool and bright and just right for running, and I was in the first few miles of a 10-mile race over a course (路线) with a few high hills. Still, I felt energetic; despite the hills it was g oing to be a fine run.Just ahead of me was Peggy Mimno, a teacher from Mount Kisco, New York. She too was running easily, moving along at my speed. The pac e(步速) felt comfortable, so 1 decided to stay where I was; why pay attention to pace when she was setting such a nice one? I'd overtake (追上) her later on when she tired.So I ran behind her. The course headed north for five miles, wandered west for a hilly mile,then turned south again along a winding road. The race was getting harder. We had four miles left and already it was beginning to be real work.Peggy overtook a young runner. She seemed to know him, for they exchanged a few cheerful words as she passed him. Their exchange worried me. You don't chat during a race unless you are feeling good, and Peggy plainly was.Still, I was close enough to overtake her if she tired, so I didn't give up hope completely. We were getting nearer to a long punishing hill now and it would be the test. We were a mile from the finish line, so whatever happened on the hill would almost certainly determine who crossed it first.As I moved up the hill, my attention wandered for a few minutes. When I looked up, Peggy was moving away--first five yards, then ten, then more. Finally it was clear that there was no hope of catching her. She beat me soundly.There is an important lesson in that race. Women are thought to be weaker, slower and not nearly as skilled in sport. Yet as Peggy Mimno so clearly showed, the similarities between men and women runners are more important than the differences. I have run with a number of women, andI can say that it is often hard work.1. What did the writer think of the race in the beginning?A. It would be hard work.C. It would be an easy race.C. It would be a test of his strength.D. It would be a good learning experience.答案: B 指导：首先要审清题干，注意题干中的inthebeginning。
