2015济南高三英语试题

2015济南高三针对性训练英语第二部分阅读理解(共两节,满分40分)第一节(共15小题;每小题2分,满分30分)阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项,并在答题卡上将该项涂黑。

AThose who believe that they will never do well in a particular area probably never will.Those who believe they are not good at anything will forever feel unprepared.But those who believe that it is possible to succeed at what they attempt can surprise themselves.Adam was ready to retire.His wife Anna,however,was less enthusiastic.As she explained to a friend,“Adam has never done anything that required physical strength.When he retires,he will sit in his easy chair and expect me to bring him his food.”But to Anna’s surprise,soon after her husband retired,he joined a health club.And one night,when Adam arrived home from exercise class,he announced,“I signed up for the wrestling tournament.I am going to wrestle Friday night.”Anna was shocked.“Please don’t do it,Adam,”she begged.“You’re not in shape.You will be so beat up that they will have to carry you home!”However,he couldn’t be persuaded and she told him that if he went through with his“lame idea”,she was not going to watch.True to her word,she stayed away as Adam wrestled.And just as she predicted,two men practically carried Adam home.He lay down on the couch,every muscle pained and wounded.Before she could speak,he blurted out,“Don’t say a word,Anna!This is not the worst of it.I won tonight.I have to wrestle again tomorrow night!”Nothing changes in your life until you believe you can do things that are important to you.And if you have a low opinion of yourself,nobody else is likely to raise it.21.How did Adam feel about his retirement? A.Worried.B.Prepared.C.Annoyed.D.Surprised.22.What does the“lame idea”in Paragraph 3 refer to?A.Adam’s joining a health club.B.Going to wrestle Friday night.C.Being beat up by other wrestlers.D.Adam’s going to be carried home.23.What can we learn from Adam’s story?A.What you believe makes a difference.B.Wrestling is a dangerous game.C.The retired man is very stubborn.D.A wife should support her husband.BBritons may like to complain a lot,but they rarely do so in the moment,explains BBC writer Ruth Margolis.They would rather grumble(发牢骚)afterward.This is because Britons hate to put someone out and cause a scene:Margolis writes:“For instance,I’m much more comfortable just leaving that piece of raw chicken on my plate instead of complaining to restaurant staff.But beware:if this kind of thing happens when you’re dining with an American,they will most likely speak up on your behalf and not understand why you find this ashamed.”In a BBC blog post comparing cultural differences between the UK and the US,Margolis mentions a few other things that Americans like to do that are offensive to Britons.●Not making introductionsMargolis says most Britons dislike this approach because“talking t o strangers without being introduced gives them a stomachache”.Americans rarely introduce a new friend to their friends at parties.Strangers are supposed to introduce themselves.●“Quite”goodUsing“quite’’to mean“very”happens a lot in the US.But if you are invited to a dinner party in Britain,don’t describe the meal as“quite good”if you want to express high praise.To Britons’ears,“quite”detracts from the“good”:the meal was OK but could have been better.●Money TalkAmericans can talk about money subjects for hours without feeling uncomfortable.For Britons,says Margolis:“talking about how much we make is unthinkable—even 1ess so than discussing our feelings”.●Over-politeness“It’s not that I want shop assistants to be actively rude.But neither do I want to expend energy responding to someone who’s been paid to ask:‘How are you today?’’’says Margolis.In the US,it is not unusual to be greeted by a perfect stranger as“honey”or“sweetie”.But Margolis says Britons find put-on friendliness,especially in stores,deeply irritating(使人生气的).24.Margolis’s dining experience in Paragraph 1 shows that_______.A.Britons are particular about foodsB.Britons are not good at complainingC.Americans usually complain directlyD.Americans complain more than Britons25.Which of the following might Margolis agree with?A.Britons enjoy talking about their feelings.B.Americans introduce themselves at parties.C.Americans dislike talking to strangers at parties.D.Britons feel happy if treated like close friends.26.The underlined phrase“detracts from”in the text probably means“____”.A.differs greatly fromB.increases the quality ofC.reduces the strength ofD.draws attention away from27.What does the text mainly talk about?A.How to get on well with westerners.B.How to start conversations with Britons.C.Ruth Margolis’s tips on public behavior.D.Some American habits that annoy Britons.CIf you had a strange sound in your ear,what would you do?One man in Wales who thought he had a fly in his ear called 999,the emergency services number in Britain.And so did a woman who was worried about her green potatoes.Could she make chips with them?Were they poisonous?She didn’t hesitate about calling the local ambulance service to ask.According to a recent report,more than 3 1,000 non-urgent calls were made to the Welsh Ambulance Service in the last year.Inappropriate calls are a headache for health professionals everywhere.In the US,prank calls to 911 happen on a daily basis.Many callers use apps which hide their identity.But those who try to be funny shouldn’t be surprised if the police have the last laugh.One man from Colorado was arrested for making more than 1,2 00 prank calls,according to a report on the US television station KOAA—TV.People who take these calls are trained to stay calm and keep a straight face,no matter how strange the call sounds.“There’s no way for us to know whether the call is real,accidental or a prank call,”said a public safety worker interviewed by the American TV channel.The Head of Clinical Services at the Welsh Ambulance Service,Richard Lee,has a warning for prank callers.He says:“When people misuse the service it means our precious time is being taken away from someone who really does need our help.”Indeed,these hotlines are supposed to help the seriously ill or those with alife-threatening injury.You never know,one day,the person who needs assistance could be you or someone in your family.28.How does the author introduce the topic of the text?A.By giving examples.B.By telling a story.C.By listing figures.D.By making a comparison.29.According to the text,prank calls are usually________.A.meant to be helpfulB.dealt with in timeC.thought highly ofD.made to play tricks30.What does the underlined phrase“have the last laugh”in Paragraph 2 probably mean?A.Win at last.B.Never find them.C.Laugh at them.D.Know nothing.31.What does the author intend to suggest in the text?A.Prank calls are usually easy to identify.B.Operators feel annoyed by strange callers.C.Prank calls may cause serious results.D.Prank callers should be punished by law.DIf you’ve ever dashed into the grocery store to pick up a tube of toothpaste,you’re likely to stop before so many options available.There are at least more than a dozen brands,each one presenting several different specialties of cleaning ability.Sometimes before you have enough time to take the costs,flavors and colors into consideration,you are warned the store is closing.But it’s not ju st the number of options that gives us pause for thought—it’s the amount of information each option has that trips us up(使某人犯错)too.Social scientist Barry Schwartz thinks in part that an abundance of choices and information may make us falsely believe that even a fairly ordinary task like shopping for toothpaste has great significance than it really does.He also points out that the Internet canactually make matters worse.Our goal is to make the“perfect”choice.When we make decisions,we’re motivated not only by the opportunity for gain,but also by the fear of loss.The decision—making process isn't a purely analytical one—researchers discovered that the process of making a choice lights up parts of our brains that deal with regret and emotional memories.But what we may regret most is the extra time spent on analyzing and comparing each and every bit of information,which can lower our decision-making ability.One good approach is to place a value on the time it takes to make your decision,compared to the value of the decision itself.In the case of toothpaste,you probably serve your interest sufficiently by quickly choosing any toothpaste that keeps white teeth securely rooted in your minty(清新的)mouth.32.We can learn from the first paragraph that_____.A.more options help people make the right decisionB.different kinds of toothpaste function similarlyC.people’s personal preferences affect their choicesD.time is wasted on making insignificant decisions33.What can we infer from the second paragraph?A.People often make wrong decisions.B.There are no small decisions in 1ife.C.The Internet provides more options.D.Careful choice iS worth the effort.34.In making choices,people have to balance____.A.time and placeB.gain and lossC.regret and memoriesD.opportunity and motivation35.The writer’s purpose in writing this text is to______.A.give advice on how to make a quick and right choiceB.show how valuable time is wasted for nothingC. describe the choice-making process in our brainD.offer tipg on how to save time when shopping第二节(共5小题;每小题2分,满分10分)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。

AToo often in life,we focus on the things we cannot do.Sometimes we cannot do things because of financial limitations,health limitations,family limitations,educational limitations,and so on.Sometimes,we end up limiting ourselves from achieving success in reaching our goals.We end up having a negative attitude which limits our ability to achieve success and happiness in our life.Through the Internet,I have recently met an individual whom I found to be very inspiring.He has a positive attitude;he focuses on what he can do.To name a few of his accomplishments:he has set a world record,and is in the Guinness Book of World Records;he is an international poet with over 900 publications;he is an advocate for the disabled;he is the founder of Beyond Limitations Week;he is an ambassador for the Harvey Ball World Smile Foundation;he has created his own website—http://wheelierecord.tripod.com/ index.html.And the list could go on!The individual is Robert M.Hensel.You see,Robert was born spina bifida,a disability that affects the sense of balance and also has an impact on the kidneys.Robert could have easily used his disability to limit his achievements,yet he has accomplished more than many.His attitude to life is one that,for me,is inspiring! To quote Robert,“I have learned that limitations open doors that have been closed,showing other ways to meet our needs.Now I look beyond what I can’t do and focus on what I can.”Let Robert be a reminder for changing attitudes.Use his motto of not focusing on what you can’t do,but focus on what you can do!21.What stops us from achieving success according to the author?A.Negative attitudes.B.Constant changes.C.Too high goals.D.Various limitations.22.What does the underlined word“one”in Paragraph 3 refer to?A.A disease.B.A disability.C.An attitude.D.A story.23.Why has Robert M.Hensel made many achievements in his life?A.He has never changed his attitude to life.B.He always looks beyond his strengths.C.He takes advantage of his disability.D.He concentrates on what he can do.24.How does the author support his idea in the text?A.By offering examples.B.By comparing attitudes.C.By analyzing limitations.D.By telling stories.BRaised by a single mother in Hartford,Fred Wright struggled with behavioral problems and was forced to move from one school to another.He even reached a point where he felt like he had nothing to live for.“I was walking around with a lot on my shoulders,”he said.“I couldn’t handle it.I didn’t care about life anymore.”But all that started to change when Wright met Patricia Kelly.“I was seven when I met Mrs Kelly.I wasn’t used to strictness.I wasn’t used to hearing the word‘no,’”said Wright,now 17.Kelly,a former soldier and an equestrian(骑手),took Wright under her wing and helped him find hope in an unlikely place—on a horse.“Wright was like a round peg that everybody kept trying to squeeze into a square hole,”Kelly said.“He was hurting.He needed a place where he could express himself.The riding field became that place for him.”For the last 30 years,Kelly has helped children stay on the right track through her nonprofit,Ebony Horsewomen.The program offers horseback riding lessons and teaches animal science to more than 300 young people a year.By exposing those children to horsemanship,Kelly aims to give them an alternative to the streets and an opportunity to turn their lives around.“We use horses as a hook to create pride,esteem and healing,”said Kelly,66.“They learn that they have ability.They just have to unlock it.”“When you teach a child to ride a horse,they learn they are the center of their environment,”said Kelly.“Once they make that connection,they can change what happens in school,at home and in the community.”25.Why did Fred Wright have to move from one school to another?A.His mother couldn’t afford the fees.B.His parents got divorced.C.He behaved badly at schoo1.D.He didn’t set a life goal.26.How did Patricia Kelly help Fred Wright?A.She provided him with a home.B.She encouraged him to learn science.C.She exposed him to the riding field.D.She found him a better schoo1.27.What do we know about the program Ebony Horsewomen?A.It is intended to make money.B.It was founded by Patricia Kelly.C.It aims to protect the environment.D.It serves as a shelter for homeless kids.28.What can be inferred from the last two paragraphs?A.Horse riding is helpful to the growth of kids.B.Patricia Kelly is a very successful woman.C.Horses are closely related to the environment.D.It is hard for a kid to 1earn to ride a horse.CThe Netherlands on Monday launched its first-ever“intelligent bicycle”,fitted with a set of electronic devices to help bring down the high accident rate among elderly cyclists in this country.The intelligent bicycle runs on electricity.Its seat shakeswhen other cyclists approach from behind,while the handlebarsdo the same when obstacles appear ahead to inform cyclists topay attention to the danger.It also has a cradle(置物架)in whicha computer can be inserted,to wirelessly connect and“talk”to the bicycle through a particular application.The computer also flashes a bright signal if there is an approaching obstacle in the bicycle’s path,like a tree,or if another cyclist comes up from behind intending to pass.A commercial-available bicycle is expected to be on the market in the next two years and should sell for between 1,700 euros to 3,200 euros per bicycle.It weighs about 55 pounds but researchers are working on making the on-board systems smaller.‘‘Accidents often happen when cyclist s look behind them or get a fright

Italian historian and novelist—Angelo Paratico,who has spent the last 20 years living and working in Hong Kong,researching the links between his homeland and China over the past half century.Mr Paratico said the documents he has uncovered during two years of research form the basis of his latest book Leonardo Da Vinci,a Chinese scholar lost in Renaissance(文艺复兴)Italy.The book,which is due to be published next year,uncovers evidence that there’s a link between Da Vinci and the Far East.Speaking to the South China Morning Post,Mr Paratico said,“I am sure that Leonardo’s mother was from the East,but to make her a Chinese,we need to use a deductive method(演绎法).One wealthy client of Leonardo’s father had a slave called Caterina.After Leonardo’s date of birth,she disappeared from the documents.She was no longer working there.’’It is believed that his mother was called Caterina,who,according to some reports,was a local peasant.But Mr Paratico’s new work claims it is most likely that Da Vinci’s mother was a slave.Supporting his theory,he said,“During the Renaissance,countries like Italy and Spain were full of slaves from the East.”He claimed that there were certain aspects of Da Vinci’s life and works which suggest a Chinese link.For instance,he was writing with his left hand from left to right and he was also a vegetarian,which was not common.Mona Lisa is probably a portrait of his mother,as Sigmund Freud said in 1910.On the back of Mona Lisa,there is a Chinese landscape and even her face looks Chinese.Mr Paratico said he believes the only way to solve the mystery is to dig out some of Da Vinci’s relations in Florence and extract some DNA.33.What is Mr Paratico’s latest book based on?A.His research findings.B.His living experience.C.His final visit to Italy.D.His interest in Renaissance.34.What may suggest there is a link between Da Vinci and Chinese?A.His working habit.B.His ways of writing.C.His birth date.D.His father’s friend.35.What can we learn about Da Vinci’s mother?A.She was a slave of Leonardo’s father.B.She quit working after her marriage.C.She was buried in Florence after death.D.She was probably the model of Mona Lisa.第二节(共5小题;每小题2分,满分10分)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。
