I got 143 cards by the end of the year,and my friend gathered 138." After winning that bet,Cavanagh decided to simply keep going with his unusual collection.He got credit cards from gas stations,airlines,bars,and even ice cream stores.If there's one card missing from Cavanagh's collection,it's that from the Newberry Company.They repulsed his application for a card in the early 1970s,even though he'd collected over 100 by then.They said he had too much credit.Therefore,so far he hasn't had a Newberry card in his collection.Cavanagh hasn't stopped applying for new cards - he's held the Guinness Record since 1971 and has no intention of letting go of it.He copies whole pages from a U.S.directory ofbusinesses and keeps sending applications.If he receives a rejection,he writes back to the company explaining his goal and ambition.But he doesn't count useless cards in his total collection.Thanks to all the cards to his name,Cavanagh has access to about $1.7 million at any moment.Despite this privilege,he has managed to maintain an excellent credit score.The 72-year-old retired financial planner and credit expert has only one piece of advice to share:"Never use a card to buy anything you can't pay off in a couple of months.If you don't have the discipline,you shouldn't have the cards."8.Cavanagh began to collect credit cards when he ______ .A. owned a very long walletB. made a bet with his friendC. wanted to create a Guinness RecordD. was treated to dinner by his friend.9.What does the underlined word "repulsed" in Paragraph 3 probably mean?______A. Rejected.B. Recalled.C. Repeated.D. Recognized.10.What do the underlined words "the discipline" in the last paragraph probably refer to?______A. Having many cards to your own name.B. Buying things by card and paying off in time.C. Managing to own more privileges for your card.D. Using a card to buy things as many times as possible.11.What do we know about Cavanagh's cards?______A. Some of them are useless.B. They are safely kept in his long wallet.C. They have brought him fame and privilege.D. Fewer new cards are added to his collections.【答案】【小题1】B 【小题2】A 【小题3】B 【小题4】C【解析】1.B.细节理解题.根据第二段中的"Cavanagh started collecting credit cards in the late 1960s.‘ One of my best friends and I made a silly bet:the guy who could collect more credit cards by the end of the year would win dinner,'he said."可知,自从跟朋友打赌后,Cavanagh就开始收集信用卡了.结合选项,故选B.2.A.词义猜测题.根据第三段中的"They said he had too much credit.Therefore,so far he hasn't had a Newberry card in his collection."可知,Cavanagh没Newberry Company的卡,表明他的申请被拒绝了.结合选项,故选A.3.B.词义猜测题.根据最后一段中的"Never use a card to buy anything you can't pay off in a couple of months."可知,Cavanagh建议人们:如果几个月内无法偿还信用贷款,那最好别用信用卡购物.结合选项,故选B.4.C.推理判断题.根据第一段中的"holds the Guinness World Record for the most credit cards"及倒数第二段中"Despite this privilege"可知,Cavanagh收藏的信用卡给他带来名声并且使他享有一些特权.结合选项,故选C.文章讲述了Walter Cavanagh拥有将近1500张信用卡,信用额度高达170万美元,创下世界纪录.做这类题材阅读理解时要求考生对文章通读一遍,做题时结合原文和题目有针对性的找出相关语句进行仔细分析,结合选项选出正确答案.推理判断题也是要在抓住关键句子的基础上合理的分析才能得出正确答案,切忌胡乱猜测,一定要做到有理有据.DStanding on one leg is a simple way to assess someone's risk of suffering a stroke (中风),suggests a new study.Researchers have found struggling to balance on one leg for 20 seconds or longer is linked to an increased risk of small blood vessel (血管)damage in the brain and reduced thinking ability in otherwise healthy people with no symptoms."Our study found the ability to balance on one leg is an important test for brain health.Individuals showing poor balance on one leg should receive increased attention,as this may indicate an increased risk of brain diseases and cognitive (认知的)decline," said Dr Tabara,a professor at Kyoto University Graduate School of Medicine in Japan.The study,published in the journal Stroke,consisted of 841 women and 546 men,with an average age of 67.To measure onelegged standing time,they stood with their eyes open and raised one leg.The maximum time for keeping the leg raised was 60 seconds.The participants performed the examination twice and the better of the two times was used in the study analysis.The researchers found that the inability to balance on one leg for longer than 20seconds was associated with brain diseases without symptoms.Overall,those with brain diseases were older and had high blood pressure than those who did not have such diseases.Short onelegged standing time was also linked with lower cognitive score.Although previous studies have examined the connection between physical abilities and the risk of stroke,this is among the first studies to closely examine how long a person can stand on one leg as an indication of their overall brain health.Dr Tabara and his team also found a strong link between struggling to stand on one leg and increased age.12.Dr Tabara suggested that one who couldn't stand on one leg for more than 20 seconds______ .A. try to improve his physical abilitiesB. receive medical treatment for brain diseasesC. be given special attention to prevent accidentsD. be examined for other symptoms of brain diseases13.Which of the following factors might decrease onelegged standing time according to thetext?______a.Heart diseases.b.Cognitive decline.c.High blood pressure.d.The aging process.e.Brain diseases.A. a,b,dB. a,c,dC. b,c,eD. b,d,e14.What can we learn about the study from the fourth paragraph?______A. It was led by Dr Tabara.B. It included more than 1,300 people.C. It examined people of different age groups.D. It required the participants to close their eyes first.15.Which of the following might be the best title for the text?______A. Overall Brain Health Deserves Close AttentionB. Brain Diseases Without Symptoms Require AttentionC. Can't Stand on One Leg?You May Be at Risk of StrokeD. Can't Keep Your Balance?You May Have Brain Damage【答案】【小题1】C 【小题2】D 【小题3】B 【小题4】C【解析】答案:1-4 CDBC1.C 细节理解题.根据第二段可知,研究发现单腿站立时间不超过20秒的人可能有更大的得脑部血管疾病的风险;根据第三段第二句可知,Tabara教授建议单腿站立平衡性差的人应当受到更多的关注,因为这类人患脑部疾病和认知能力下降的风险很大.故选C.2.D.理解推断题.根据倒数第二段Short onelegged standing time was also linked with lower cognitive score.Although previous studies have examined the connection between physical abilities and the risk of stroke,this is among the first studies to closely examine how long a person can stand on one leg as an indication of their overall brain health.单腿站立的时间越短,认知得分越低,尽管先前的研究已经检查了体能和中风的风险之间的联系,这是第一批深入研究单腿站立的时间长短的研究之一,以此作为大脑整体健康状况的指标.倒数第一段Dr Tabara and his team also found a strong link between struggling to stand on one leg and increased age.Tabara 博士和他的研究小组还发现,单腿站立困难与年龄增长之间存在密切联系,因此与认知、大脑健康、年龄有关,故选D.3.B 细节理解题.根据第四段第一句中的consisted of 841 women and 546 men可知,这项研究共有1,387人参与,故选B.4.C 标题概括题.本文主要介绍了一项新的研究发现:通过一个人单腿站立的时间长短,研究人员能够推断出其患中风风险的大小,故选C.一项新研究发现,通过一个人单腿站立的时间长短能够推断出其患中风风险的大小以及认知能力是否下降.考察学生的细节理解和推理判断能力,做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确的选择.在做推理判断题不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.二、阅读七选五(本大题共5小题,共10.0分)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 life.Some people say we live in a dog-eat-dog world.(2) .They say if a person wants to be successful he 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.But mean dogs are often used 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 hottestdays of the year.A rain in summer may cool the weather.But we do not want it to rain too hard.(5) .A.We do not want it to rain cats and dogs.B.Still,people say every dog has its day.C.Some people are compared to dogs in bad days.D.There are many other expressions waiting for you to explore.E.Dogs are their best friends and they are loyal to people.F.That means many people are competing for the same things,like good jobs.G.They take their dogs for walks,let them play outside and give them good food and medical care.16.

ALife experiences can show one’s “grit”(坚韧). Complex challenges early in life helped the following people develop skills that got them to the top of their professions.Ursula Burns, Chairwoman, VEON; Former CEO, XeroxHer family was so poor that her single mother traded office cleaning for health care. But Burns’ early gift for maths won her a scholarship and an internship at Xerox, where she would compete her way to the top. “ I’m a black lady from the Lower East Side,” she says, “Not a lot scares me.”Howard Schultz, Executive Chairman, StarbucksSchultz grew up in public housing in Brooklyn, surrounded by poverty, and was the first in his family to go to college (on a football scholarship). After training in sales, he set up the company that would later buy Starbucks. “In the course of the year I spent trying to raise money, I spoke to 242 people, and 217 of them said no.” he said.Sean Combs, CEO, Sean JohnCombs began a generation of hip-hop talent and made a lasting influence on fashion. But his story could have turned out much differently: His drug dealer father was killed when he was 3. “It made me work even harder.” he recently said.Geisha Williams, CEO, PG&EHer parents fled Cuba when Williams was 5. By 7, she was her parents main translator in talks with lawyers and accountants at grocery stores they owned.The experience did help her. “I went from thinking I could be a manager to thinking I could do something mu ch bigger.” she told Fortune.21.

Poor family kids can be successful easily.D. Difficulty in life pushed Williams forward.BDear Alcohol,You’ve been around forever. I can remember all the pain you’ve caused me.Do you remember the night when you almost took my father’s life? I do. He loves you. Sometimes I think he loves you more than he loves me. He’s addicted to you,to the way you promise to rid him of his problems only to cause more of them.You just sat back and laughed as his car went turning through the street,crashing into two other cars. He wasn’t the only one badly hurt by you that night.Do you remember the night of my first high school party? My friends were intrigued by you. They treated you as if they were never going to see you again,drinking all of you that they could.I spent two hours that night helping my friends who had fallen head over heels for you. “I’m so embarrassed,” they said as I held their hair back so that they could throw up. “I’m sorry,” they said when I called taxis for them,walking them out and paying the driver in advance. “This won’t happen again,” they said as they were sent to the hospital to have their stom achs pumped.Two 15-year-old girls slept in hospital beds that night due to you.Do you remember the night when you took advantage of my 17-year-old neighbor who had to drive to pick up his sister from her dance lesson? Do you know how we all felt when he hit another car head-on and killed two people in the other car? He died the next morning, too. His sister walked home from her dance lesson,and passed police cars and a crowd of people gathering on the sidewalk just two blocks away from the dance studio. Sh e didn’t realize her brother was among them at all. She never saw him again. And it was all your fault.I wish you’d walk out of my life forever. I don’t want anything to do with you. Look at all the pain you’ve caused. Sure, you’ve made people happy too f rom time to time. But the damage you’ve caused in the lives of millions is not excusable. Stop attracting the people I love! Stop hurting me, please!Sincerely,Me24. What did Alcohol do to the author’s father that night?A. It made him drunk and took his life away.B. It made him kill two other people when he was driving.C.

To warn people against the pain caused by alcohol.27. How was the author feeling while writing this letter?A. Shocked.B. Responsible.C. Disappointed.D. Sorrowful.CWorking up a credit score for Walter Cavanagh has got to be a mathematical nightmare —the man has nearly 1,500 valid credit cards to his name and holds the Guinness Record for the most credit cards. Mr. Plastic Fantastic — a title given to him by Guinness World Records — is also the p roud owner of the world’s longest wallet, which can hold about 800 cards. But he uses it only to carry a few cards, while the rest are safely kept in bank safedeposit boxes.Cavanagh started collecting credit cards in the late 1960s. “One of my best frien ds and Imade a silly bet: the guy who could collect the most credit cards by the end of the year would win dinner,” he said. “I got 143 cards by the end of the year, and my friend gathered 138.” After winning that bet, Cavanagh decided to simply keep going with his unusual collection. He got credit cards from gas stations, airlines, bars, and even ice cream stores.If there’s one card missing from Cavanagh’s collection, it’s that from the Newberry Company. They repulsed his application for a card in the ea rly 1970s, even though he’d collected over 100 by then. They said he had too much credit. Therefore, so far he hasn’t had a Newberry card in his collection.Cavanagh hasn’t stopped applying for new cards —he’s held the Guinness Record since 1971 and has no intention of letting go of it. He copies whole pages from a U.S. directory of businesses and keeps sending applications. If he receives a rejection, he writes back to the company explaining his goal and ambition. But he doesn’t count useless cards in his total collection.Thanks to all the cards to his name, Cavanagh has access to about $1.7 million at any moment. Despite this privilege, he has managed to maintain an excellent credit score.The 72-year-old retired financial planner and credit expert has only one piece of advice to share: “Never use a card to buy anything you can’t pay off in a couple of months. If you don’t have the discipline, you shouldn’t have the cards.”28. Cavanagh began to collect credit cards when he ________.A. owned a very long walletB. made a bet with his friendC. wanted to create a Guinness RecordD. was treated to dinner by his friend.29. What does the underlined word “repulsed” in Paragraph 3 probably mean?A. Rejected.B. Recalled.C. Repeated.D. Recognized.30. What do the underlined words “the discipline” in the last paragraph probably refer to?A. Having many cards to your own name.B. Buying things by card and paying off in time.C. Managing to own more privileges for your card.D. Using a card to buy things as many times as possible.31. What do we know about Cavanagh’s cards?A. Some of them are useless.B. They are safely kept in his long wallet.C. They have brought him fame and privilege.D. Fewer new cards are added to his collections.DStanding on one leg is a simple way to assess someone’s risk of suffering a stroke (中风), suggests a new study.Researchers have found struggling to balance on one leg for 20 seconds or longer is linked to an increased risk of small blood vessel (血管) damage in the brain and reduced thinking ability in otherwise healthy people with no symptoms.“Our study found the ability to balance on one leg is an important test for brain health. Individuals showing poor balance on one leg should receive increased attention, as this may indicate an increased risk of brain diseases and cognitive (认知的) decline,” said Dr Tabara, a professor at Kyoto University Graduate School of Medicine in Japan.The study, published in the journal Stroke, consisted of 841 women and 546 men, with an average age of 67. To measure onelegged standing time, they stood with their eyes open and raised one leg. The maximum time for keeping the leg raised was 60 seconds. The participants performed the examination twice and the better of the two times was used in the study analysis.The researchers found that the inability to balance on one leg for longer than 20 seconds was associated with brain diseases without symptoms. Overall, those with brain diseases were older and had high blood pressure than those who did not have such diseases.Short onelegged standing time was also linked with lower cognitive score. Although previous studies have examined the connection between physical abilities and the risk of stroke, this is among the first studies to closely examine how long a person can stand on one leg as an indication of their overall brain health.Dr Tabara and his team also found a strong link between struggling to stand on one leg and increased age.32. Dr Tabara suggested that one who couldn’t stand on one leg for more than 20 seconds________.A. try to improve his physical abilitiesB. receive medical treatment for brain diseasesC. be given special attention to prevent accidentsD. be examined for other symptoms of brain diseases33. Which of the following factors might decrease onelegged standing time according to the text?a. Heart diseases.b. Cognitive decline.c. High blood pressure.d. The aging process.e. Brain diseases.A. a, b, dB. a, c, dC. b, c, eD. b, d, e34. What can we learn about the study from the fourth paragraph?A. It was led by Dr Tabara.B. It included more than 1,300 people.C. It examined people of different age groups.D. It required the participants to close their eyes first.35. Which of the following might be the best title for the text?A. Overall Brain Health Deserves Close AttentionB. Brain Diseases Without Symptoms Require AttentionC. Can’t Stand on One Leg? You May Be at Risk of StrokeD. Can’t Keep Your Balance? You May Have Brain Damage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, 选项中有两项为多余选项。

I got 143 cards by the end of the year,and my friend gathered 138." After winning that bet,Cavanagh decided to simply keep going with his unusual collection.He got credit cards from gas stations,airlines,bars,and even ice cream stores.If there's one card missing from Cavanagh's collection,it's that from the Newberry Company.They repulsed his application for a card in the early 1970s,even though he'd collected over 100 by then.They said he had too much credit.Therefore,so far he hasn't had a Newberry card in his collection.Cavanagh hasn't stopped applying for new cards - he's held the Guinness Record since 1971 and has no intention of letting go of it.He copies whole pages from a U.S.directory ofbusinesses and keeps sending applications.If he receives a rejection,he writes back to the company explaining his goal and ambition.But he doesn't count useless cards in his total collection.Thanks to all the cards to his name,Cavanagh has access to about $1.7 million at any moment.Despite this privilege,he has managed to maintain an excellent credit score.The 72-year-old retired financial planner and credit expert has only one piece of advice to share:"Never use a card to buy anything you can't pay off in a couple of months.If you don't have the discipline,you shouldn't have the cards."8.Cavanagh began to collect credit cards when he ______ .A. owned a very long walletB. made a bet with his friendC. wanted to create a Guinness RecordD. was treated to dinner by his friend.9.What does the underlined word "repulsed" in Paragraph 3 probably mean?______A. Rejected.B. Recalled.C. Repeated.D. Recognized.10.What do the underlined words "the discipline" in the last paragraph probably refer to?______A. Having many cards to your own name.B. Buying things by card and paying off in time.C. Managing to own more privileges for your card.D. Using a card to buy things as many times as possible.11.What do we know about Cavanagh's cards?______A. Some of them are useless.B. They are safely kept in his long wallet.C. They have brought him fame and privilege.D. Fewer new cards are added to his collections.【答案】【小题1】B 【小题2】A 【小题3】B 【小题4】C【解析】1.B.细节理解题.根据第二段中的"Cavanagh started collecting credit cards in the late 1960s.‘ One of my best friends and I made a silly bet:the guy who could collect more credit cards by the end of the year would win dinner,'he said."可知,自从跟朋友打赌后,Cavanagh就开始收集信用卡了.结合选项,故选B.2.A.词义猜测题.根据第三段中的"They said he had too much credit.Therefore,so far he hasn't had a Newberry card in his collection."可知,Cavanagh没Newberry Company的卡,表明他的申请被拒绝了.结合选项,故选A.3.B.词义猜测题.根据最后一段中的"Never use a card to buy anything you can't pay off in a couple of months."可知,Cavanagh建议人们:如果几个月内无法偿还信用贷款,那最好别用信用卡购物.结合选项,故选B.4.C.推理判断题.根据第一段中的"holds the Guinness World Record for the most credit cards"及倒数第二段中"Despite this privilege"可知,Cavanagh收藏的信用卡给他带来名声并且使他享有一些特权.结合选项,故选C.文章讲述了Walter Cavanagh拥有将近1500张信用卡,信用额度高达170万美元,创下世界纪录.做这类题材阅读理解时要求考生对文章通读一遍,做题时结合原文和题目有针对性的找出相关语句进行仔细分析,结合选项选出正确答案.推理判断题也是要在抓住关键句子的基础上合理的分析才能得出正确答案,切忌胡乱猜测,一定要做到有理有据.DStanding on one leg is a simple way to assess someone's risk of suffering a stroke (中风),suggests a new study.Researchers have found struggling to balance on one leg for 20 seconds or longer is linked to an increased risk of small blood vessel (血管)damage in the brain and reduced thinking ability in otherwise healthy people with no symptoms."Our study found the ability to balance on one leg is an important test for brain health.Individuals showing poor balance on one leg should receive increased attention,as this may indicate an increased risk of brain diseases and cognitive (认知的)decline," said Dr Tabara,a professor at Kyoto University Graduate School of Medicine in Japan.The study,published in the journal Stroke,consisted of 841 women and 546 men,with an average age of 67.To measure onelegged standing time,they stood with their eyes open and raised one leg.The maximum time for keeping the leg raised was 60 seconds.The participants performed the examination twice and the better of the two times was used in the study analysis.The researchers found that the inability to balance on one leg for longer than 20seconds was associated with brain diseases without symptoms.Overall,those with brain diseases were older and had high blood pressure than those who did not have such diseases.Short onelegged standing time was also linked with lower cognitive score.Although previous studies have examined the connection between physical abilities and the risk of stroke,this is among the first studies to closely examine how long a person can stand on one leg as an indication of their overall brain health.Dr Tabara and his team also found a strong link between struggling to stand on one leg and increased age.12.Dr Tabara suggested that one who couldn't stand on one leg for more than 20 seconds______ .A. try to improve his physical abilitiesB. receive medical treatment for brain diseasesC. be given special attention to prevent accidentsD. be examined for other symptoms of brain diseases13.Which of the following factors might decrease onelegged standing time according to thetext?______a.Heart diseases.b.Cognitive decline.c.High blood pressure.d.The aging process.e.Brain diseases.A. a,b,dB. a,c,dC. b,c,eD. b,d,e14.What can we learn about the study from the fourth paragraph?______A. It was led by Dr Tabara.B. It included more than 1,300 people.C. It examined people of different age groups.D. It required the participants to close their eyes first.15.Which of the following might be the best title for the text?______A. Overall Brain Health Deserves Close AttentionB. Brain Diseases Without Symptoms Require AttentionC. Can't Stand on One Leg?You May Be at Risk of StrokeD. Can't Keep Your Balance?You May Have Brain Damage【答案】【小题1】C 【小题2】D 【小题3】B 【小题4】C【解析】答案:1-4 CDBC1.C 细节理解题.根据第二段可知,研究发现单腿站立时间不超过20秒的人可能有更大的得脑部血管疾病的风险;根据第三段第二句可知,Tabara教授建议单腿站立平衡性差的人应当受到更多的关注,因为这类人患脑部疾病和认知能力下降的风险很大.故选C.2.D.理解推断题.根据倒数第二段Short onelegged standing time was also linked with lower cognitive score.Although previous studies have examined the connection between physical abilities and the risk of stroke,this is among the first studies to closely examine how long a person can stand on one leg as an indication of their overall brain health.单腿站立的时间越短,认知得分越低,尽管先前的研究已经检查了体能和中风的风险之间的联系,这是第一批深入研究单腿站立的时间长短的研究之一,以此作为大脑整体健康状况的指标.倒数第一段Dr Tabara and his team also found a strong link between struggling to stand on one leg and increased age.Tabara 博士和他的研究小组还发现,单腿站立困难与年龄增长之间存在密切联系,因此与认知、大脑健康、年龄有关,故选D.3.B 细节理解题.根据第四段第一句中的consisted of 841 women and 546 men可知,这项研究共有1,387人参与,故选B.4.C 标题概括题.本文主要介绍了一项新的研究发现:通过一个人单腿站立的时间长短,研究人员能够推断出其患中风风险的大小,故选C.一项新研究发现,通过一个人单腿站立的时间长短能够推断出其患中风风险的大小以及认知能力是否下降.考察学生的细节理解和推理判断能力,做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确的选择.在做推理判断题不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.二、阅读七选五(本大题共5小题,共10.0分)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 life.Some people say we live in a dog-eat-dog world.(2) .They say if a person wants to be successful he 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.But mean dogs are often used 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 hottestdays of the year.A rain in summer may cool the weather.But we do not want it to rain too hard.(5) .A.We do not want it to rain cats and dogs.B.Still,people say every dog has its day.C.Some people are compared to dogs in bad days.D.There are many other expressions waiting for you to explore.E.Dogs are their best friends and they are loyal to people.F.That means many people are competing for the same things,like good jobs.G.They take their dogs for walks,let them play outside and give them good food and medical care.16.

2018-2019学年安徽省黄山市高二上学期期末考试语文试题 Word版
黄山市2018~2019年度第一学期期末质量检测高二语文试题说明:试卷分第Ⅰ卷(阅读题)和第Ⅱ卷(表达题)两部分。
全卷满分150分,考试时间150分钟。
第Ⅰ卷(阅读题)一、现代文阅读(9分)阅读下面的文字,完成1—3题。
①佛、道二教同传统儒家并称“三教”。
三教自并立以来,既相互排斥争斗,也相互吸收、不断融合,成为中国文化一大特色。
儒家自汉武帝“罢黜百家,独尊儒术”之后逐渐成为官方意识形态。
与此同时,佛教精微而高深的义理,道教的神仙方术、长生不老思想对皇帝贵族和一般士人有着巨大的吸引力;因果轮回、鬼神报应又迎合了普通大众的迷信心理。
故无论儒家如何抵制,佛道二教的声势和影响日渐扩大,包括小说在内的艺术领域亦受其浸染。
②三教在融合的过程中,不断向世俗化推进,以求贴近广大下层民众,扩大影响。
这在小说中有大量的反映。
《太平广记》载唐代俳优李可及以倡优身份讲论三教,言释迦如来、太上老君、文宣王皆为妇人。
将三教所奉教主作为取笑逗乐的对象,虽有不敬之嫌,但客观上反映了当时较为宽松的文化环境,以及三教间融洽的关系,而皇帝听罢“意极欢,宠锡颇厚”,也表明统治者乐见三教间和谐共处。
③唐宋文言小说中三教思想的融合方式有两种:一是在一部小说中收入了表现三家思想的故事,这早在魏晋南北朝时期的《世说新语》《搜神记》等作品中已有所表现;另一种方式是在一则故事中反映出两家甚至三家思想。
唐宋文言小说中存在大量有意模糊佛道界限的作品,僧人道士化、道士僧人化。
例如,《广异记•刘清真》中的五台山僧人即是佛道一体的形象。
④中国古代的三教融合往往呈现“以儒家为主导,释道二教向其靠拢”的形态,如释道二教都将“忠”“孝”置于教义中的重要地位。
唐代佛教类书《法苑珠林》中设有“君臣”“纳谏”“忠孝”等类目,显示了佛教典籍对儒家思想的吸收。
道教作为本土宗教,对儒家伦理道德的提倡和强调较佛教更加主动,葛洪明确将“忠孝和顺仁信”作为修道的前提,其戒律要求信徒“不得不忠不孝不仁不信,当尽节君亲,推诚万物”。

safely kept in bank safedeposit boxes.Cavanagh started collecting credit cards in the late1960s."One of my best friends and I made a silly bet:the guy who could collect the most credit cards by the end of the year would win dinner,"he said."I got143cards by the end of the year,and my friend gathered138."After winning that bet,Cavanagh decided to simply keep going with his unusual collection.He got credit cards from gas stations,airlines,bars,and even ice cream stores.If there's one card missing from Cavanagh's collection,it's that from the Newberry Company.They repulsed his application for a card in the early1970s,even though he'd collected over100by then.They said he had too much credit.Therefore,so far he hasn't had a Newberry card in his collection.Cavanagh hasn't stopped applying for new cards-he's held the Guinness Record since1971and has no intention of letting go of it.He copies whole pages from a U.S.directory of businesses and keeps sending applications.If he receives a rejection,he writes back to the company explaining his goal and ambition.But he doesn't count useless cards in his total collection.Thanks to all the cards to his name,Cavanagh has access to about$1.7million at any moment.Despite this privilege,he has managed to maintain an excellent credit score.The72-year-old retired financial planner and credit expert has only one piece of advice to share:"Never use a card to buy anything you can't pay off in a couple of months.If you don't have the discipline,you shouldn't have the cards."8.Cavanagh began to collect credit cards when he______.A.owned a very long walletB.made a bet with his friendC.wanted to create a Guinness RecordD.was treated to dinner by his friend.9.What does the underlined word"repulsed"in Paragraph3probably mean?______A.Rejected.B.Recalled.C.Repeated.D.Recognized.10.What do the underlined words"the discipline"in the last paragraph probably refer to?______A.Having many cards to your own name.B.Buying things by card and paying off in time.C.Managing to own more privileges for your card.ing a card to buy things as many times as possible.11.What do we know about Cavanagh's cards?______A.Some of them are useless.B.They are safely kept in his long wallet.C.They have brought him fame and privilege.D.Fewer new cards are added to his collections.【答案】【小题1】B【小题2】A【小题3】B【小题4】C【解析】1.B.细节理解题.根据第二段中的"Cavanagh started collecting credit cards in the late1960s.‘One of my best friends and I made a silly bet:the guy who could collect more credit cards by the end of the year would win dinner,'he said."可知,自从跟朋友打赌后,Cavanagh就开始收集信用卡了.结合选项,故选B.2.A.词义猜测题.根据第三段中的"They said he had too much credit.Therefore,so far he hasn't had a Newberry card in his collection."可知,Cavanagh没Newberry Company 的卡,表明他的申请被拒绝了.结合选项,故选A.3.B.词义猜测题.根据最后一段中的"Never use a card to buy anything you can't pay off in a couple of months."可知,Cavanagh建议人们:如果几个月内无法偿还信用贷款,那最好别用信用卡购物.结合选项,故选B.4.C.推理判断题.根据第一段中的"holds the Guinness World Record for the most credit cards"及倒数第二段中"Despite this privilege"可知,Cavanagh收藏的信用卡给他带来名声并且使他享有一些特权.结合选项,故选C.文章讲述了Walter Cavanagh拥有将近1500张信用卡,信用额度高达170万美元,创下世界纪录.做这类题材阅读理解时要求考生对文章通读一遍,做题时结合原文和题目有针对性的找出相关语句进行仔细分析,结合选项选出正确答案.推理判断题也是要在抓住关键句子的基础上合理的分析才能得出正确答案,切忌胡乱猜测,一定要做到有理有据.DStanding on one leg is a simple way to assess someone's risk of suffering a stroke(中风),suggests a new study.Researchers have found struggling to balance on one leg for20seconds or longer is linked to an increased risk of small blood vessel(血管)damage in the brain and reduced thinking ability in otherwise healthy people with no symptoms."Our study found the ability to balance on one leg is an important test for brain health.Individuals showing poor balance on one leg should receive increased attention,as this may indicate an increased risk of brain diseases and cognitive(认知的)decline,"said Dr Tabara,a professor at Kyoto University Graduate School of Medicine in Japan.The study,published in the journal Stroke,consisted of841women and546men,with an average age of67.To measure onelegged standing time,they stood with their eyes open and raised one leg.The maximum time for keeping the leg raised was60seconds.The participants performed the examination twice and the better of the two times was used in the study analysis.The researchers found that the inability to balance on one leg for longer than20seconds was associated with brain diseases without symptoms.Overall,those with brain diseases were older and had high blood pressure than those who did not have such diseases.Short onelegged standing time was also linked with lower cognitive score.Although previous studies have examined the connection between physical abilities and the risk of stroke,this is among the first studies to closely examine how long a person can stand on one leg as an indication of their overall brain health.Dr Tabara and his team also found a strong link between struggling to stand on one leg and increased age.12.Dr Tabara suggested that one who couldn't stand on one leg for more than20seconds______.A.try to improve his physical abilitiesB.receive medical treatment for brain diseasesC.be given special attention to prevent accidentsD.be examined for other symptoms of brain diseases13.Which of the following factors might decrease onelegged standing time according to thetext?______a.Heart diseases.b.Cognitive decline.c.High blood pressure.d.The aging process.e.Brain diseases.A.a,b,dB.a,c,dC.b,c,eD.b,d,e14.What can we learn about the study from the fourth paragraph?______A.It was led by Dr Tabara.B.It included more than1,300people.C.It examined people of different age groups.D.It required the participants to close their eyes first.15.Which of the following might be the best title for the text?______A.Overall Brain Health Deserves Close AttentionB.Brain Diseases Without Symptoms Require AttentionC.Can't Stand on One Leg?You May Be at Risk of StrokeD.Can't Keep Your Balance?You May Have Brain Damage【答案】【小题1】C【小题2】D【小题3】B【小题4】C【解析】答案:1-4CDBC1.C细节理解题.根据第二段可知,研究发现单腿站立时间不超过20秒的人可能有更大的得脑部血管疾病的风险;根据第三段第二句可知,Tabara教授建议单腿站立平衡性差的人应当受到更多的关注,因为这类人患脑部疾病和认知能力下降的风险很大.故选C.2.D.理解推断题.根据倒数第二段Short onelegged standing time was also linked with lower cognitive score.Although previous studies have examined the connection between physical abilities and the risk of stroke,this is among the first studies to closely examine how long a person can stand on one leg as an indication of their overall brain health.单腿站立的时间越短,认知得分越低,尽管先前的研究已经检查了体能和中风的风险之间的联系,这是第一批深入研究单腿站立的时间长短的研究之一,以此作为大脑整体健康状况的指标.倒数第一段Dr Tabara and his team also found a strong link between struggling to stand on one leg and increased age.Tabara博士和他的研究小组还发现,单腿站立困难与年龄增长之间存在密切联系,因此与认知、大脑健康、年龄有关,故选D.3.B细节理解题.根据第四段第一句中的consisted of841women and546men可知,这项研究共有1,387人参与,故选B.4.C标题概括题.本文主要介绍了一项新的研究发现:通过一个人单腿站立的时间长短,研究人员能够推断出其患中风风险的大小,故选C.一项新研究发现,通过一个人单腿站立的时间长短能够推断出其患中风风险的大小以及认知能力是否下降.考察学生的细节理解和推理判断能力,做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确的选择.在做推理判断题不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.二、阅读七选五(本大题共5小题,共10.0分)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 life.Some people say we live in a dog-eat-dog world.(2).They say if a person wants to be successful he 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.But mean dogs are often used 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 thehottest days of the year.A rain in summer may cool the weather.But we do not want it to rain too hard.(5).A.We do not want it to rain cats and dogs.B.Still,people say every dog has its day.C.Some people are compared to dogs in bad days.D.There are many other expressions

vocabulary from the dialect ofChina's Guangdong Province.In other parts of the country including Beijing,however,it(3)(know)as"qipao",which has a history behind it.After the early Manchu(满族的)rulers came to China,the Manchu women wore(4)(normal)a onepiece dress which came to be called"qipao".(5)the1911Revolution ended the rule of the Qing Dynasty,the female dress survived the political change and,with later improvements,has become the traditional dress for Chinese women.The cheongsam,(6)neck is high,collar closed,fits well the Chinese female figure,and its sleeves may be either short,medium or full(7)(long),depending on seasons or tastes.In addition,it is not too complicated(8)(make).Nor(9)it need too much material.Another beauty of the cheongsam is that it can be worn

known【小题4】normally【小题5】Although/Though/While【小题6】whose【小题7】length【小题8】to make【小题9】does【小题10】on【解析】1.popularity考查名词.enjoy是及物动词,后接名词作宾语.故填popularity.2.meaning考查现在分词.分析句子结构可知此处应用现在分词形式作后置定语,相当于定语从句"which means…".故填meaning.3.is known,考查被动,主语是it,而且是一般现在时,be known as:作为…被熟知,故填is known.4.normally考查副词.wear是动词,要用副词形式来修饰动词.故填normally.5.Although/Though/While考查连词.句意:尽管1911年的辛亥革命结束了清朝的统治,但旗袍在这次政治变革中被保留了下来….用连词Although/Though/While引导让步状语从句.故填Although/Though/While.6.whose考查定语从句.分析句子结构可知这是一个定语从句,先行词cheongsam在从句中作定语,用关系代词whose.7.length考查名词.根据句意:(旗袍的)袖子可以是短袖,中袖,也可是长袖."length"表达表达"长度"之意,故填length.8.to make考查特殊句型.too…to…句型为"too+形容词或副词+to do…"译为"太…而不能…",它在形式上是肯定的,但在意义上是否定的,to do不定式应用主动形式表示被动含义.故填to make.9.does考查倒装句.上句话提到的情况同样适合下文的人或物,为了避免和上文的内容重复,英语习惯用so,neither/nor引导的倒装句.so引导的倒装句表示肯定,neither/nor引导的倒装句表示否定,其时态与前一句时态保持一致,上下文陈述的不是同一人或事物.根据文中时态应用一般现在时,且句子主语为第三人称单数形式,用does.10.on考查介词.表示"在…场合"时,用短语on…occasions.故填介词on.本文主要介绍旗袍.旗袍是独具中国特色的女性服饰,在高端时尚的国际世界中日益流行.上身容易,穿着舒适,旗袍特别适合中国女性的身材.它的好处在于可以使用多种材质,并以不同长度制作,因此在休闲和正式场合都可穿着.对于语法填空这类题,一是懂得分析句子结构,二是知道充当各个句子成分的词类或词性,从语法上确定答案,当然,对于某些固定搭配也要牢记,在平时的学习中要多积累这些词汇或短语,对于句子使用的时态语态也要通过语境进行确定.五、短文改错(本大题共1小题,共10.0分)42.假定英语课上老师要求同桌之间交换修改作文,请你修改你同桌写的以下作文.文中共有10处语言错误,每句中最多有两处.每处错误仅涉及一个单词的增加、删除或修改.增加:在缺词处加一个漏字符号(︿),并在其下面写出该加的词.删除:把多余的词用斜线(\)划掉.修改:在错的词下划一横线,并在该词下面写出修改后的词.注意:1.每处错误及其修改均仅限一词;2.只允许修改10处,多者(从第11处起)不计分.There are many people think that wealth is better than health.I used to think so until one day I had read a story about Howard Joyce.He was an European billionaire who got everything he wanted.Therefore,in the last twenty years of his life,his health began to get worse and he led a miserably life.Although the best doctors called for him,he could still find no relief.I have realized that health is worth all the money in the world.If you have million of dollars but you are at poor health,you will not be able to do what you want to do.So I would like to advise you not to hurt yourself to trying to make money.Instead,take care of your body and be happy with which you do.Health is more important.【答案】There are many people think that wealth is better than health.I used to think so until one day Ihad read a story about Howard Joyce.He was an European billionaire who got everything he wanted.Therefore,in the last twenty years of his life,his health began to get worse and he led a miserably

health,you will not be able to do what you want to do.So I would like to advise you not to hurt yourself to trying to make money.Instead,take care of your body and be happy with which you do.Health is more important.1.将think改为thinking或think前加who.考查现在分词或定语从句.根据句子结构分析,There are many people为完整句子,此处用现在分词thinking表主动关系作后置定语,或者在think前加who构成定语从句,先行词为people,在从句作主语,指人用关系代词who,故将think改为thinking或think前加who.2.去掉had.考查动词时态.根据句子结构分析,由one
