第Ⅰ卷阅读题一、现代文阅读(35分)(一)沦述类文本阅读(9分,每小题3分)阅读下面的文字,完成1~3题。
何谓“精神”?就字源来讲,“精”是细微之义,“神”是能动的作用之义。
文化的基本精神就是文化发展过程中精微的内在动力,也就是指导民族文化不断前进的基本思想。
文化的基本精神是一定文化创造出来,并成为该文化思想基础的东西。
中国文化丰富多彩,思想博大精深,因而中国文化的基本思想也不是单纯的,而是一个包括诸多要素的统一体系。
这个体系的要素主要有四点:刚健有为,和与中,崇德利用,天人协调。
其中“天人协调”思想主要解决人与自然的关系;“崇德利用”思想主要解决人自身的关系,即精神生活与物质生活的关系;“和与中”的思想主要解决人与人的关系,包括君臣、父子、朋友等人伦关系;而“刚健有为”思想则是处理各种关系的人生总原则四者以“刚健有为”思想为纲,形成中国文化基本思想的体系。
“刚健有为”思想源于孔子,到战国时期的《周易大传》已见成熟。
《周易大传》提出来的“刚健有为”思想包括“自强不息”和“厚德载物”两个方面。
《象传》说:“天行健,君子以自强不息。
”天体运行,永无已时,故称为“健”。
君子法天,故应“自强不息”。
“自强不息”也就是努力向上,绝不停止。
《周易大传》所说的“刚健”,还有“独立不惧”“立不易方”之义,也就是孟子所说的“富贵不能淫,贫贱不能移”的独立人格。
《象传》又说:“地势坤,君子以厚德载物。
”“坤”即顺,“载物”就是包容许多物类。
君子应效法大地的胸怀,包容各个方面的人,容纳不同的意见,使他人和万物都得以各遂其生。
《周易大传》认为,健是阳气的本性,顺是阴气的本性,在二者之中,阳健是居于主导地位的。

21.(6分)When he was young, Louis Armstrong was taking what was called “Creole jazz”, which was also called dance music, and combining it with trumpeter(小号手) Buddy Bolden, to create what would eventually become today’s jazz.Armstrong accomplished this with almost no formal training. He received little training before he was placed in the New Orleans Colored Waif’s Home at the age of 12, after a run-in(小争执) with the police. The punishment turned out to be a mixed blessing, for he also had the opportunity to play in a real band.While at the Waif’s, Armstrong also got the chance to hear some of the city’s finest musicians. Cornetist Freddie Keppard performed in a nearby club. So did trumpeter and bandleader King Joe Oliver,who took the boy under his wing and taught him how to read music and work on his playing technique.When Oliver left for Chicago, Armstrong chose to stay in New Orleans and work with some of the other top musicians of the day. In Chicago, King Oliver offered him a place in his band in 1922. It became Armstrong’s biggest challenge yet — the band had no parts written for trumpet, so he was forced to listen to King Oliver and improvise(即兴创作).Soon, Armstrong’s undeniable talent was getting noticed. Even classically trained musicians would come to hear the incredible sounds this young man created.Lil Hardin, the band’s piano player and the future Mrs. Armstrong, explained that Oliver kept Armstrong in the second trumpet-chair so that Oliver would still be “King”. Hardin convinced him to leave the band.Armstrong moved to New York City in 1924 to join Fletcher Henderson’s band and then flew solo. In 1925, Armstrong put together the Hot Five, expanding his popularity even more. Armstrong recorded his first composition, Cornet Chop Suey, one of the most copied jazz solos of all time. This monumental 1928 recording blends(混合) artistry, endurance and showmanship that has rarely, if ever, been matched in jazz.1、What does the underlined word “this” refer to in the second paragraph?A.To play dance music. B.To work with Buddy Bolden.C.To play a jazz instrument well. D.To create modern jazz music.2、Who taught Louis Armstrong how to play music in the early time?A.Buddy Bolden. B.Lil Hardin.C.King Joe Oliver. D.Cornetist Freddie Keppard.3、Why did Louis Armstrong Leave King Oliver’s band?A.Because he wanted to get married in New York.B.Because his talent could not develop completely.C.Because he got a better opportunity in New York.D.Because the man forced him to leave the band.4、What’s the ma in idea of the passage?A.It asks readers to know more about modern jazz.B.It introduces one of the greatest jazz musicians.C.It introduces the development of jazz.D.It describes the importance of talent in playing jazz.22.(8分)When a special occasion arrives,a colorful gift bag or a box often finds its way to a doorstep,an office desk or a mailbox.But once in a while,a present arrives at an unexpected moment as a reminder that someone is thinking about us.Wanda Anderson of Richland,US,remembers such a gift.The rosebushes were finally in full bloom on that day in spring.Seeing roses always brings to mind Wanda's childhood memories.To this young girl,those flowers were a luxury."We never had money to buy extra things,so even a tired rose was something to cherish," Wanda said.Nowadays,to have a backyard filled with many different roses is pure enjoyment.Wanda especially loves the very first blooms.Her husband,Dale,devotedly tends the roses and knows this little fact about his wife.So,on this particular morning,he picked the very first flowers of spring,fresh from the garden.But as Dale came back into the house,he was met by a neighbor who had stopped in for a quick visit.As the woman turned to go,Dale graciously (有风度地)handed the roses to her.And even though their visitor insisted she didn't want to take them,she was repeatedly convinced that the flowers were hers to keep."I told her I was happy for her to have the roses,but I really wasn't," Wanda said,recalling the emotions she was feeling right then.Seeing her very precious first blooms go out of the door filled her with regret,and a bit of selfishness.Throughout the rest of the morning,Wanda argued with herself,knowing logically it was "better to give than to receive." Nevertheless,she wished she could have kept the roses for herself.Later that day,the couple headed to the post office,where Wanda waited outside in the car.Then,without warning,an older woman suddenly appeared at the car's open window,with a bunch of multicolored roses in her arms."These are for you," she said,giving the flowers to Wanda."They're my first blooms this spring." Totally surprised and overwhelmed (不知所措的),Wanda thanked the woman and bent for a moment to inhale (吸入)the roses' rich fragrance.When she looked back,the mysterious visitor was gone.To this day,that "special delivery" changed Wanda.Now,her very first blooms always go to someone else,as a reminder that someone is thinking of them.1、Why does Wanda love roses so much?______A.She thinks that they stand for pure love.B.She was given them often as a child.C.Her husband always sends her roses.D.She couldn't afford them when she was young.2、How did Wanda feel after the neighbor left?______A.Worried.B.Upset.C.Satisfied.D.Relieved.3、What changed Wanda's opinion of giving gifts?______A.The flowers her husband bought her.B.The gifts her neighbor gave back to her.C.The roses she received from a stranger.D.A mysterious delivery she got from the post office.4、Why does Wanda always give away her roses to others now?______A.To show off her beautiful flowers.B.To prove that she isn't selfish.C.To surprise people she loves.D.To show that she's thinking of them.23.(8分)The following are the largest Latino companies in terms of revenue across the country, according to .Brightstar Corp.

In 1994, they merged with Burnup & Sims, a construction company that specialized in telephone networks in the US, the Caribbean, Middle East and Pacific Islands, becoming MasTec Corporation.In the next decades, they accomplished enough growth to build complex infrastructure projects in renewable energy, electric power, gas and oil, water and sewers, communications andinstallation-fulfillment services.Molina healthcare (revenue: US $3.0 billion)Since Dr. C.David Molina, MD, opened his first clinic in Long Beach, California, in 1980, he set up the vision of his company to provide quality healthcare for low-income families and those under coverage provided by the government who were using emergency room services instead of general healthcare services.Now, Molina Healthcare, a public company, delivers health services and health information management solutions to almost five million families in 15 states.Greenway Ford(revenue: US $1.2 billion)Frank Rodriguez is the founder of Greenway Ford, a group of 26 dealerships(代理商)in the Orlando area and the core of Greenway Automotive Group.1、Which of the following is the biggest Latino company?A.Molina Healthcare B.MasTec IncC.Brightstar Corp D.Greenway Ford2、Which is NOT included in complex infrastructure projects of Mas Tec Inc?A.Water and sewers B.Non-renewable energyC.Gas and oil D.Electric power3、Previously, the company of Dr. C.D avid Molina provided low-income families with ________.

If you had attended a winter activity in New Yor k a few years ago, you would have seen a whole polar bear club. These “Polar Bears” are people who meet frequently in the winter to swim in freezing cold water. That day, the air temperature was 3℃, and the water temperature was a little higher. The members of the Polar Bear Club at Coney Island, New York are usually about the age of 60. Members must satisfy two requirements. First, they must get along well with everyone else in the group. This is very important because there are so many different kinds of people in the club. Polar Bears must also agree to swim outdoors at least twice a month from November through February.Doctors do not agree about the medical effects of cold-winter swimming. Some are worried about the dangers of a condition in which the b ody’s temperature drops so low that finally the heart stops. Other doctors, however, point out that there is more danger of a heart attack during summer swimming because the difference between the air temperature and water temperature is much greater in summer than in winter.The Polar Bears themselves are satisfied with the benefits (or advantages) of cold-water swimming. They say that their favorite form of exercise is very good for the circulatory system (循环系统) because it forces the blood to move fast to keep the body warm. Cold-water swimmers usually turn bright red after a few minutes in the water. A person who turns blue probably has a very poor circulatory system and should not try cold-water swimming.The main benefits (or advantages) of cold-water swimming are probably mental. The Polar Bears love to swim all year round. They find it fun and relaxing. As one 70-year-old woman says. “When I go into water, I pour my troubles into the ocean and let them float away.”1、The members of the Polar Bear Club must meet the following requirements EXCEPT that .A.they must reach the age of 60B.they should be easy to make friends withC.they must swim outdoors at least 8 times in the four cold monthsD.they must agree to swim outdoors from November through February2、According to the passage, some doctors believe it is true that .A.you are healthy if cold-water swimming turns your skin color blueB.cold-water swimming causes more heart attacks in summer than in winterC.cold-water swimming can make the body temperature dangerously highD.Polar Bears are bears swimming in freezing water3、The Polar Bears like to swim all the year round, for .A.they can remain youngB.it is an easy way to keep the body warm in winterC.they find it enjoyable and interestingD.they might meet fewer troubles in life25.(10分)A recent trend in California restaurants shows new eating habits among those out to have an interesting dining experience. Appetizer(开胃品) seem to be the name of the games as diners turn away from the more traditional three-course meal in favor of smaller snacks sampled in various types of restaurants, bars and cafes. In this way, in the course of an evening out, you might go to a restaurant for a tasty dish to eat at one end of town, to a bar with some live music at the other end, then for a coffee, and finally back to the restaurant for a further appetizer.Reasons for this trend are the fact that so many different types of restaurants have been set up recently, each with their own particular type of food and special atmosphere, combined with the increased quality in the type of snacks being offered. Gone are the cheese sticks of the old days, when appetizers were not really taken seriously. Some favorite snacks of the moment are slices of hot pizza, creamy fish-based dishes and crispy cakes and so on.Prices for appetizers are not equal to a full meal; however, their new popularity has meant that are by no means as cheap as they used to be. Certainly, for that special occasion, a meal in a nice restaurant, complete with the piano performance, is hard to beat. However, if we see that this trend for “butterfly eating” —moving around several different places in one evening—continues, then all the traditional style restaurants may well have to provide their own appetizer bars as well!1、Which of the following could best reflect the change of California people’s eating habits?A.People love more interesting restaurants.B.Most people eat less than they used to.C.A full restaurant meal is losing popularity.D.Food is combined with sports and games.2、What can we learn from Paragraph 2 that ________.A.appetizers used to be relatively importantB.the quality of snacks has been improvedC.restaurants have to cater for different customersD.new-style appetizers fueled the boom of catering business3、Diners who prefer appetizers of new types ________.A.will be charged moreB.will be served betterC.can enjoy music performanceD.can eat in their neighborhood第三部分语言知识运用(共两节)第一节(每小题1.5分,满分30分)阅读下面短文,从短文后各题所给的A、B、C和D四个选项中,选出可以填入空白处的最佳选项.26.(30分)Our family’s first hosting experience began in January of 2015 with our Italian daughter Victoria.
