1.(2014届江西省九所重点中学高三下学期3月联合考试英语试卷)My father was a foreman of a sugar-cane plantation in Rio Piedras, Puerto Rico. My first job was to drive the oxen that ploughed the cane fields. I would walk behind an ox, guiding him with a broomstick. For $1 a day, I worked eight hours straight, with no food breaks.It was very tedious work, but it prepared me for life and taught me many lasting lessons. Because the plantation owners were always watching us, I had to be on time every day and work as hard as I could. I’ve never been late for any job since. I also learned about being respectful and faithful to the people you work for. More importantly, I earned my pay, it never entered my mind to say I was sick just because I didn’t want to work.I was only six years old, but I was doing a man’s job. Our family needed every dollar we could make because my father never earned more than $18 a week. Our home was a three-room wood shack with a dirty floor and no toilet. Nothing made me prouder than bringing home money to help my mother, father, two brothers and three sisters. This gave me self-esteem(自尊心), one of the most important things a person could have.When I was seven, I got work at a golf course near our house. My job was to stand down the fairway and spot the balls as they landed, so the golfers could find them. Losing a ball meant you were fired, so I never missed one. Some nights I would lie in bed and dream of making thousands of dollars by playing golf and being able to buy a bicycle.The more I dreamed, the more I thought. Why not? I made my first golf club out of guava limb (番石榴树枝) and a piece of pipe. Then I hammered an empty tin can into the shape of a ball. And finally I dug two small holes in the ground and hit the ball back and forth. I practiced with the same devotion and intensity. I learned working in the field--- except now I was driving golf balls with club, not oxen with a broomstick.43.The writer’s first job was ___________.A. to stand down the fairway at the golf courseB. to watch over the sugar-cane plantationC. to drive the oxen that ploughed the cane fieldsD. to spot the balls as they landed so the golfers could find them44.The underlined word “tedious” in Paragraph 2 most probably means ___________.A. difficultB. boringC. interestingD. unusual45.The writer learned that ________ from his first job.A. he should work for those who he liked mostB. he should work longer than what he was expectedC. he should never fail to say hello to his ownerD. he should show respect and faith to the people he worked for46.________ gave the writer self-esteem.A. Having a family of eight peopleB. Owning his own golf courseC. Bringing money back home to help the familyD.

He wanted to run a golf course near his house.C. He was satisfied with the job he got on a plantation.D. He wanted to make money by guiding oxen with a broomstick.2. (2014届广东省揭阳市高三3月第一次模拟英语试卷)One year our family decided to have a special celebration of Mother’s Day, as a token of appreciations for all the sacrifices that Mother had made for us. After breakfast we had arranged, as a surprise, to hire a car and take her for a beautiful drive in the country. Mother was rarely able to have a treat like that, because she was busy in the house nearly all the time.But on the very morning of the day, we changed the plan a little, because it occurred to Father that it would be even better to take Mother fishing. As the car was hired and paid for, we might as well use it to drive up into the hills where the streams are. As Father said, if you just go driving without object, you have a sense of aimlessness, but if you are going to fish there is a definite purpose that heightens the enjoyment.So we all felt it would be nicer for Mother to have a definite purpose . Father had just got a fishing rod the day before, which he said mother could use if she wanted to. Only Mother said shewould much rather watch him fish than try to fish herself.So we got her to make up a sandwich lunch in case we got hungry, though we were to come home again to a big festive dinner.Well, when the car came to the door, it turned out that there was not as much space in it as we had supposed. It was plain that we couldn’t all get in.Father said that he could just stay home and put in the time working in the garden. He said that there was a lot of rough dirty work that he could do, like digging a trench for the garbage, which would save hiring a man, and so he said that he’d stay home; he said that we were not to let the fact that he had not had a real holiday for three years stand in our way. He wanted us to go right ahead and not to mind him.But of course we all felt that it would never do to let Father stay home, especially as we knew he would make trouble if he did. The two girls, Anne and Mary, would have stayed and helped the maid get dinner, only it seemed such a pity,for the two girls were eager to show their new hats on a lovely day like this. But they said that Mother had only to say the word and they’d gladly stay home and work. Will and I would have dropped out, but unfortunately we wouldn’t have been any use in preparing the dinner.48.The author’s family decided to celebrate Mother’s Day specially to _______.A. show love for their motherB. show gratitude to their motherC. show respect for their motherD. to make up for a previous appointment49.According to Paragraph 2, we know that the plan was changed because________.A. Father proposed to go fishing outB. we thought that driving out is boringC. we failed to hire a car to go outD. the car was not big enough50.What problem did we find when the car arrived?A. The car was too old to drive on mountain roads.B. The car was larger than we expected.C. The car was too small to accommodate us all.D. The car was too plain looking.51.Why didn’t the author drop out of the activity?A. Because his sisters didn’t join in.B. Because he needed to have dinner.C. Because he couldn’t cook the dinner.D. Because he hadn’t had a real holiday for three years.52.Which of the following proverbs describes the text best?A. Everything comes to him who waits.B. Changes always go beyond plans.C. Better late than never.D. Once on shore, one prays no more.3.(2014届福建省龙岩市高三毕业班教学质量检查英语试卷)It was the last day of July and the long hot summer was drawing to a close As for me.1 was out of spirits,and,if the truth must be told, out of money as well,During the past year I had not managed my finances as carefully as usual;and 1 was now limited to spending the autumn economically between my mother’s cottage at Hampstead and my own in town.My father had been dead for some years,and my sister and 1 were the sole survivors of a family of five children. My father was a drawing-master before me He had been highly successful in his profession and my mother and sister were left economically independent after his death.The view of London below me had sunk into the black shadow of the cloudy night, when I stood before the gate of my mother’s cottage I had hardly rung the bell.When the house door was opened violently.My worthy Italian friend,Professor Pesca,appeared in the servant’s place,and rushed out joyously to receive me.I had first become acquainted(熟悉)with my Italian friend at certain great houses,where he taught Italian and I taught drawing What I then knew of the history of his life was that he had left Italy for political reasons and that he had been respectably established for many years in London as a teacher of languages It once happened that I saved him from certain death by drowning while wewere swimming in the sea at Brighton Afterwards he overwhelmed(淹没)me with the wildest expressions of affection and exclaimed passionately, that he would hold his life at my disposal fromthen on, and declared that he should never be happy again until he had had the opportunity of proving his gratitude.Little did I think that the occasion to serve me was soon to come.Pesca dragged me in by both hands into the parlor, where my mother sat by the open window, laughing and fanning herself.Pesca was one of her especial favorites,and his wildest strange acts were always pardonable in her eyes.“Now, my good dears.”began Pesca.“listen to me The time has come I recite my good news.I speak at last…'Hear, hear!”said my mother, humoring the joke“I go back into my life,and I address myself to the noblest of men,who found me dead at the bottom of the sea,and who pulled me up to the top. What did I say when l got into my own life and my own clothes again? I said that my life belonged to my dear friend,Walter, for the rest of my days Now,”cried the enthusiastic little mall at the top of his voice.“happiness bursts out of me at every pore of my skin.For I have found a job for you”53.The first two paragraphs of the passage serve as an introduction to——A. the financial situation the writer then facedB. the season that the story was set inC. the family members of the writerD. the successful profession of the writer’s father54.The underlined word‘‘sole’’in the second paragraph probably means‘‘”A.main B. only C. lucky D. possible55.It can be learned from the passage that PescaA. used to be a politicianB. was a successful drawing-masterC. was quite close to the motherD. wanted to give the writer some money in return56.According to the last paragraph,Pesca was more than happy becauseA. he went back into his lifeB . he met his dear friend againC. his friend ever saved his lifeD. he had done something good for his friend4.(2014届浙江省“六市六校”联盟高考模拟考试英语试卷)On a sunny day last August, Tim heard some shouting. Looking out to the sea carefully, he saw a couple of kids in a rowboat were being pulled out to sea.Two 12-year-old boys, Christian and Jack, rowed out a boat to search for a football. Once they'd rowed beyond the calm waters, a beach umbrella tied to the boat caught the wind and pulled the boat into open water. The pair panicked and tried to row back to shore. But they were no match for it and the boat was out of control.Tim knew it would soon be swallowed by the waves."Everything went quiet in my head," Tim recalls (回忆). "I was trying to figure out how to swim to the boys in a straight line."Tim took off his clothes and jumped into the water. Every 500 yards or so, he raised his head to judge his progress. "At one point, I considered turning back," he says. "I wondered if I was putting my life at risk." After 30 minutes of struggling, he was close enough to yell to the boys, "Take down the umbrella!"Christian made much effort to take down the umbrella. Then Tim was able to catch up and climb aboard the boat. He took over rowing, but the waves were almost too strong for him."Let's aim for the pier (码头)," Jack said. Tim turned the boat toward it. Soon afterward, waves crashed over the boat, and it began to sink. "Can you guys swim?" he cried. "A little bit," the boys said.Once they were in the water, Tim decided it would be safer and faster for him to pull the boys toward the pier. Christian and Jack were wearing life jackets and floated on their backs. Tim swam toward land as water washed over the boys' faces.“Are we almost there?" they asked again and again. "Yes," Tim told them each time.After 30minutes, they reached the pier.57.Why did the two boys go to the sea?A. To go boat rowing.B. To swim in the open water.C. To get back their football.D.

They were carried to the pier by Tim on his back.B. They swam to the pier all by themselves.C. They were washed to the pier by the waves.D. They were dragged to the pier by Tim.5.(2014届宁夏银川一中高三第一次模拟考试英语试卷)John Blanchard stood up from the bench, straightened his Army uniform, and studied the crowd of people making their way through Grand Central Station. He looked for the girl whose heart he knew, but whose face he didn’t, the girl with the rose.His interest in her had begun thirteen months before in a Florida library. Taking a book off the shelf he found himself intrigued, not with the words of the book, but with the notes penciled in the margin. The soft handwriting reflected a thoughtful soul and insightful mind. In the front of the boo k, he discovered the previous owner’s name, Miss Hollis Maynell. With time and effort he located her address. She lived in New York City. He wrote her a letter introducing himself and inviting her to correspond. The next day he was shipped overseas for service in World War II.During the next year and one month the two grew to know each other through the mail. Each letter was a seed falling on a fertile heart. A romance was starting Blanchard requested a photograph, but she refused. She felt that if he rea lly cared, it wouldn’t matter what she looked like.When the day finally came for him to return from Europe, they scheduled their first meeting —7:00 PM at the Grand Central Station in New York. “You’ll recognize me,” she wrote, “by the red rose I’ll be wearing on my lapel.” So at 7:00 he was in the station looking for a girl whose heart he loved, but whose face he’d never seen.I’ll let Mr. Blanchard tell you what happened: A young woman was coming toward me, her figure long and slim. Her blonde hair lay back in curls from her delicate ears; her eyes were blue asflowers. Her lips and chin had a gentle firmness, and in her pale green suit she was like springtime come alive. I stared at her, entirely forgetting to notice that she was not wearing a rose. As I moved, a small, attractive smile curved her lips. “Going my way , sailor?” she murmured.Almost uncontrollably I made one step closer to her, and then I saw Hollis Maynell. She was standing almost directly behind the girl. A woman well past 40, she had graying hair tucked under a worn hat. She was more than plump, her thick-ankled feet thrust into low-heeled shoes. The girl in the green suit was walking quickly away. I felt as though I was split in two, so keen was my desire to follow her, and yet so deep was my longing for the woman whose spirit had truly companioned me and upheld my own.And there she stood. Her pale, plump face was gentle and sensible, her gray eyes had a warm and kindly twinkle. I did not hesitate. My fingers gripped the small worn blue leather copy of the book that was to identify me to her.This would not be love, but it would be something precious, something perhaps even better than love, a friendship for which I had been and must ever be grateful. I squared my shoulders and saluted and held out the book to the woman, even though while I spoke I felt choked by the bitterness of my disappointment."I'm Lieutenant John Blanchard, and you must be Miss Maynell. I am so glad you could meet me; may I take you to dinner?"The woman's face broadened into a tolerant smile. "I don't know what this is about, son," she answered, "but the young lady in the green suit who just went by, she begged me to wear this rose on my coat. And she said if you were to ask me out to dinner, I should go and tell you that she is waiting for you in the big restaurant across the street. She said it was some kind of test!"It's not difficult to understand and admire Miss Maynell's wisdom. The true nature of a heart is seen in its response to the unattractive. "Tell me whom you love," Houssaye wrote, "And I will tell you who you are."61.How did John Blanchard get to know Miss Hollis Maynell?A. They lived in the same city.B.

Don't Judge a Book by its Cover6.(2014届江西省六校高三下学期联考英语试卷)A few days ago I asked my sons’ governess(女家庭教师)Julia to come into my study. “Be seated, Julia, ” I said, “Let’s settle our accounts. I guess you most likely need some money, but maybe you’re too polite to mention it. Now then, we agreed on thirty dollars a month...”“Forty.”“No, thirty. I made a note of it. I always pay our governess thirty. Well, um, you’ve been here two months, so...”“Two months and five days.”“Exactly two months. I made a special note of it. That means you have sixty dollars coming to you. Take off nine Sundays... you know you didn’t work with Tom on Sundays, you only took walks. And three holidays... ”Julia was biting her finger nail nervously, her face red, but - not a word.“Three holidays, therefore take off twelve dollars. Four days Tom was sick and there were no lessons, as you were occupied only with Dick. Three days you had a toothache and my wife gave you permission not to work after lunch. Twelve and seven - nineteen. Take nineteen off ... that leaves. hmm.... forty one dollars. Correct?”Julia’s left eye reddened with tears welling up. Her chin trembled; she coughed nervously and blew her nose, but-still not a word.“Around New Year’s Day you broke a teacup and a sa ucer; take off two dollars. The cup cost more, it was a treasure of the family, but- forget it. When didn’t I take a loss! Then, due to your neglect(疏忽), Tom climbed a tree and tore his jacket; take away ten. Also due to your carelessness the maid stole Di ck’s shoes. You ought to watch everything! You get paid for it. So, that means five more dollars off. The tenth of January I gave ten dollars.”“You didn’t. ”sobbed Julia.“But I made a note of it.”“Well... if you say so.”“Take twenty seven from forty one -that leaves fourteen.”Both her eyes were filled with tears. Beads of sweat stood on the thin pretty little nose. Poor girl!“Only once was I given any money,” she whispered, her voice trembling, “and that was by your wife. Three dollars, no thing more.”“Really? You see now, and I didn’t know that! Take three from fourteen.. leaves eleven. Here’s your money, my dear. Three, three, three, one and one. Here it is!”I handed her eleven dollars. She took them and pocketed them.“Merci(法语: 谢谢),” she whispered.I jumped to my feet and started pacing the room. I was overcome with anger. “For what, this - ‘merci’?” I asked.“For the money.”“But you know I’ve cheated you - robbed you! I have actually stolen from you! Why this‘merci’?”“In my other places they didn’t give me anything at all.”“They didn’t give you anything? No wonder! I played a little joke on you, a cruel lesson, just to teach you... I m going to give you all the eighty dollars! Here they are in the envelope all ready for you... Is it really possible to be so spineless(懦弱)? Why didn’t you protest? Why were you silent? Is it possible in this world to be without teeth and claws(爪)-to be such a fool?”Embarrassed, she smiled. And I could read her expression,“It is possible.”I asked her pardon for the cruel lesson and, to her great surprise, gave her the eighty dollars. She murmured her little“merci”several times and went out. I looked after her and thought,“How easy it is to crush the weak in this world!”67.While talking to Julia, the writer expected from her________.A. a protestB. gratitudeC. obedienceD. an explanation68.What shocked the writer was Julia’s ________.A. nervousness in front of her bossB. acceptance of injusticeC. shyness when talking about moneyD. unwillingness to express herself69.The writer said, “Is it possible in this world to be without teeth and claws?” He was actually telling the governess ________.A. to be more aggressiveB. to be more careful in her workC. to protect her rightD. to live independently70.At the end of the story, the writer said,“ How easy it is to crush the weak in this world!” to show ________.A. his understanding of Julia’s anxietyB. his worry about Julia’s futureC. his concern on the living condition of working-class peopleD. his sympathy for the mental state of those exploited71.From the story, we can tell that Julia’s employer was________.A. greedy but honestB. ill-tempered but warm-heartedC. strict but forgivingD. none of the above 【答案及其解析】【答案】43.C44.B45.D46.C47.A【解析】【答案】48.B49.A50.C51.C52.B【解析】文章讲述作者和家人决定用特殊的方式庆祝母亲节,为了向母亲表示感激,在活动准备过程中一些事情总是预想不到的改变这计划,但最终得到合理的安排。
2015考前演练湖南卷演练四答案
2015年普通高等学校招生全国统一考试考前演练(四)湖南卷答案1.D2.C(这个句子是用比喻的说法,说明情书和它曾经的书写工具鹅毛笔、墨水瓶一样成为历史。
B、D两项,“情书凝固成湛蓝的一坨”、“情书似乎凝固成湛蓝的一坨”都不合清理,原文段说“情书”“鹅毛笔”和“墨水瓶”“凝固成湛蓝的一坨”是用形象地说法表明,它们都已成历史;A项少了“似乎”一词,就不是比喻了,当然不合文意。
)3.A【题干与A项的“随便”是“不经心;随意”的意思;B项的“随便”是“(言行)不多考虑;不慎重”的意思;C项的“随便”是“按照某人的方便”的意思;D项的“随便”是“大气、豪爽”的意思。
】4.B(此四项都有开阔的空间,但A项是表现因开阔而怅惘,C项是表现因开阔而博大雄浑,D项是表现因开阔而孤独寂寞,只有B项是表现因开阔而蕴藉,看似空旷,实则另有内涵。
这就与文段的意思相吻合了。
)5.B(雅是“交往”的意思。
)6.C【盖,大概(是),表测度;之,用于主谓之间,取消主谓结构的独立性;而,就。

)9.(1)我禀性刚直简慢,学问迂阔,才质驽钝,因事连年被谪,不敢再自居于士大夫行列。
(2)扬雄喜欢用艰深的辞藻来文饰浅显易懂的意思,假如直截了当地说出来,就人人都能明白了。
(3)文章像赤金美玉,市上本有定价,不是凭谁的一句话就能论定价格的贵贱。
10.(1)寄给妻子(2)一、二句没有说“别后心”究竟如何,三、四句却通过所写的途中景色来表现作者情怀的极苦、极乱。
首句在字面上提出了“途中景”,却全无一字说此“景”;第二句提出了“别后心”,却既不作心情的描述,又无形象以表现含义。
诗到后面又转回头去接第一句写“途中景”。
如此安排,等于告诉读者景即心,心即景,与其写不易着笔的抽象心情,不如写引起此种情怀的实景,于实景中见到这种极苦、极乱的心情,将虚化实,使实处全虚,则更易感人。

AThey say that good wine needs no bush, but a TV show means that people now know Li Jian is a fine wine indeed.On the reality show I am a Singer 3, the 40-year-old singer and song writer has been praised for his Singing ability and, unexpectedly, for his sense of humor. On stage, Li sings quiet songs slowly and “rescues the program”, commented Cheng Zhenwei on People’s Daily Online.Harbin-born Li has a clear and smooth voice, which he inherited from his Peking Operas inger father. And his shy nature and poetic lyrics have also given him the nickname “Poetic Musician”.“In my younger days, music was like therapy,” he told China Daily.Music was also the bridge that got him into Tsinghua University. A self-taught guitarist, Li won a number of singing competitions. He was admitted thanks to Tsinghua’s plan to recruit(招募) students with musical talent.In the 1990s, so-called “campus ballads” were popular in China. Shuimu Nianhua, a group that Li formed with another Tsinghua student called Lu Gengxu, was one of the best groups of the type.But the pair went their separate ways in 2002. Li was tired of doing commercial performances. Also, he didn’t agree with their decision to change their style form folk to rock.Afterward, Li released several albums on his own. They were all in his own musical style: “soft and warm, down-to-earth and intimate”, commented China Radio International.Unlike some other musicians who release their songs quickly, Li took his time to write with heart felt music.“Writing songs is like collecting water in a cup. When the cup is full, the water comes out naturally, ” he told China Daily.For nearly ten years, he did very few interviews or concerts. His low-key life may well have continued if Faye Wong hadn’t sung his song, Legend, at 2010’s CCTV Spring Festival Gala.Li said the song brought him out of his “cave” and back into spotlight: concerts and reality shows have been endless, including this year’s I Am a Singer.26. The author mentioned the good wine in the first paragraph to ________.A. compare Li Jian to great wineB. show that Li Jian likes good wineC. introduce the topic of the passageD. attract readers’ attention to good wine27. Why is Li Jian called a “Poetic Musician”?A. Because he has a shy nature and poetic lyrics.B. Because he can write poems and sing well at the same time.C.

Other members wanted to change their style from folk to rockC. Li was tired of doing commercial performancesD. Both B and C29.What does the underlined sentence mean?A. When musicians are writing songs, they should collect a cup of water.B. Musicians should release their songs quickly.C. Li Jian thought that writing songs needed time to write heart felt music.D. The time Li Jian took to write a song was the same as he collected a cup of water.30.What’s the main idea of the passage?A. Li Jian became popular after attending an reality show I am a Singer 3.B. Some information about an reality show I am a Singer 3.C. A brief introduction of Li Jian and his music.D. Li Jian has been praised for his singing ability and sense of humor.BA long-term study has pointed to a link between breastfeeding and intelligence.The research in Brazil traced nearly 3,500 babies, from all walks of life, and found those who had been breastfed for longer went on to score higher on IQ tests as adults.Dr Bernardo Lessa Horta, from the Federal University of Pelotas in Brazil, said his study offers a unique insight because in the population he studied, breastfeeding was evenly distributed across social class - not something just practiced by the rich and educated.Most of the babies, irrespective of social class, were breastfed - some for less than a month and others for more than a year. Those who were breastfed for longer scored higher on measures of intelligence as adults. They were also more likely to earn a higher wage and to have completed more schooling.Dr Horta believes breast milk may offer an advantage because it is a good source of long-chain saturated fatty acids which are essential for brain development. But experts say the study findings cannot confirm this and that much more research is needed to explore any possible link between breastfeeding and intelligence.Kevin Fenton, Public Health England, said there was strong evidence that breastfeeding provides some health benefits for babies - reduced respiratory and gastrointestinal infections in infancy, for example.He said: "PHE’s advice is that babies should be exclusively breastfed for six months. But they say mothers should still have a choice about whether or not to do it. We recognize however, that not all mothers choose, or are able, to breastfeed and infant formula is the only alternative to breast milk for babies under 12 months old."Dr Colin Michie, chairman of the Royal College of Paediatrics and Child Health’s nutrition committee, said: "There have been many studies on the link between breastfeeding and IQ over the years with many having had their validity challenged."This study however, looks at a number of other factors including education achievement and income at age 30 which makes this study a very powerful one."It is important to note that breastfeeding is one of many factors that can contribute to a child’s outcomes, however this study emphases the need for conti nued and enhanced breastfeeding promotion so expectant mothers are aware of the benefits of breastfeeding."31.What can we know about the experimental subjects of the study?A. They pointed to a link between breastfeeding and intelligence.B. They were nearly 3,500 babies from all over the world.C. Most of them were breastfed.D. They were from the rich and educated families.32.What does Dr. Horta believe?A. His study is a unique one.B. Only the rich and educated breastfeed their babies.C. Breast milk is essential for brain development.D.More research is needed to explore any possible link between breastfeeding andintelligence.33.What can we know from Kevin Fenton’s words?A. That breastfeeding provides health benefits for babies needs strong evidence.B. Mothers choose infant formula for babies under 12 month old.C. Infant formula reduced respiratory and gastrointestinal infections in infancy.D. Not all the babies can be breastfed.34.Which of the following words has the close st meaning to “exclusively”?A. At mostB. At leastC. NearlyD. Frequently35.The purpose of the passage is to tell the readers that ________.A. Longer breastfed babies were more likely to become smarter adults.B. Longer breastfed babies were more likely to earn a higher wage as adults.C. Longer breastfed babies were more likely to complete more schooling.D. Longer breastfed babies were more likely to become rich and educated.CWith the coming of Halloween, doggy costume contests and parades may be held at pet businesses like Petco and PetSmart, and local stores will have details. Dog lovers often include their dogs in the plans. Sometimes rescue groups, like the Haute Dog organization in Long Beach, California, hold Halloween festivities for dogs as a way to raise funds for homeless pets.For ten years, Justin Rudd, Haute Dogs founder, has arranged a celebration that includes a parade, vendor booths, and a costume contest for both dogs and kids. Other fun activities include a pet adoption fair, a dog treat stacking contest, and probably the wildest of all, a Lick or Treat booth where, for only $1 you can get a big sloppy face lick and kiss from a Bulldog. Worth every penny!This year they expect more than 500 costumed dogs and several thousand spectators to show up. And, as in the past, all this fun is expected to raise thousands of dollars for spay/neuter programs, Operation Santa Paws and Haute Dogs.If your dog is one of those well behaved, friendly sorts, you may want to check the Internet, newspapers, shelters, and vet offices for information on local Halloween celebrations that include dogs. Many of these benefit homeless animals. Finding a costume for your dog can be really fun and easy. Pet costumes have become quite popular and are available online, and in many retail stores, including dollar stores, or you can be creative and make your own.If you choose to stay home, you and your dog can still dress up in costume and give out some healthy treats to any dogs who may come trick-or-treating. Part of Halloween family fun can be gathering the kids in the kitchen and making some homemade doggy treats.It’s a good idea to give the family a quick brush-up on Halloween safety for dogs before the celebration begins. With all the gooey, sugary goodies floating around, it’s importa nt that all, especially chocolates, are kept well out of reach of the dog. Remember also that many treats contain xylitol(木糖醇) which is poisonous to dogs. Not all dogs like parties or enjoy attention from strangers. Some are actually frightened by the costumes. If your dog is one of these, his feelings should be respected. Let him stay in a safe place at home where he will feel secure. You can always take him some treats after all the festivities are over.36.Why do rescue groups sometimes hold Halloween festivals for dogs?A.To have fun during Halloween.B.To raise money for homeless pets.C.To find out the best dog.D.To arise people’s awareness of pet protection.37.Which of the following activities is probably the wildest?A. A pet adoption fair.B. A costume contest for both dogs and kids.C. A dog treat stacking contest.D. A Lick or Treat booth38. We can know from Paragraph 4 that ________.A.People can get information on Halloween activities in different ways.B.Every dog is welcome to take part in the contest.C.Pet costumes are popular and are mainly sold online.D.It is interesting but expensive to find a costume for the dog.39.What shall we do about extremely shy dogs?A.Dress them up in costume.B.Go to many parties with them.C.Draw people’s attention to them.D.Let them enjoy safety at home.40. The best title for this passage should be ________.A.How to enjoy your Halloween.B.The importance of Halloween.C.Halloween activities for dogs.D.How to make the dogs happy.DIf you’re trying to find out what to study in college, a new report suggests you would do well choosing a major in science, technology, engineering or math.The report, based on Census and National Science Foundation data analyzed by the Georgetown University Center on Education and the Workforce, shows that professions that depend heavily on skills learned in these fields are the second-fastest growing occupational group in the United States, after health care.While traditional fields like computer engineering and laboratory research make up about 5 percent of the work force, demand for science, technology, engineering and math skills is spreading far beyond, to occupations in manufacturing, transportation and mining, as well as to sales and management. As a result, the study argues that there is a shortage of so-called STEM workers.With a shortage of people trained in such fields, many technology and scientific companies in the United S tates are forced to employ people from abroad, the study’s authors say.According to the study, people with talent in science, technology, engineering or math don’t often major in such subjects during college in the first place. Of those graduating with such degrees, only 10 percent go into related fields such as engineering, physical science or architecture.Compared with many other fields outside of these majors, STEM workers can earn higher wages. On average, 65 percent of those who hold a bachelor’s deg ree in such fields will earn more than those who hold master’s degrees in other subjects. Among those with associate’s degrees inthe science and technical fields, 63 percent earn more than those who hold bachelor’s degrees in other subjects.“I’m used to thinking of liberal arts as the foundational degree that gives you lots of choices in a career,” Mr. Carnevale said. Increasingly, he said, science, technology, engineering and math are important to a wide-ranging career. “You get a bigger bump going in, a nd almost at every stage you have other choices,” he said.But don’t count philosophy or literature out, either. Mr. Carnevale said that in surveys of employers, one of the biggest complaints about technical workers is that they “can’t talk and can’t write a memo and have horrible interpersonal skills.” So maybe the best course of study is a double major.41.According to the report, which is the fastest growing occupational group?A. EducationB. Health careC. ScienceD. Accounting42.What do many technology and scientific companies do in the USA because of a shortage ofSTEM workers?A. They .plan to train STEM workers by themselves.B. They hire STEM workers from foreign countries.C. They persuade colleges to train more STEM workers.D. They want to give up hiring STEM workers .43. We can conclude from the passage that ________.A. A science degree is gaining a rising value.B. Everyone should major in science, technology, engineering or math.C. People with a science degree will have the best future.D. Most people with a science degree go into related fields.44. Mr. Carnevale believes that ________.A. Philosophy and literature are not so important for people with science degree.B. Employers focus only on workers practical skills in related fields.C. Employers pay little attention to technical workers’ interpersonal skills.D. People with science degree will have other choices in their career.45.What is purpose of this passage?A. To persuade.B. To educate.C. To inform.D. To advise.第二节信息匹配(共5题;每小题2分,满分10分)阅读下列应用文及相关信息,并按照要求匹配信息。
