He moved there a few years ago, and I was eager to see his new place andmeet his friends.My earliest memories of my father are of a tall, handsome, successful mandevoted to his work and family but uncomfortable with his children. As a child I lovedhim; as a school girl and young adult, I feared him and felt bitter about him. Heseemed unhappy with me unless I got straight A’s and unhappy with my boyfriends iftheir fathers were not as “successful” as he was. Whenever I went out with him on weekends, I used to struggle to think up things to say, feeling on guard.On the first day of my visit, we went out with one of my father’s friends for . We walked along that afternoon, did some shopping andlunch at an outdoor cafélaughed over my son’s funny facial expressions, gone with my father’s critical(挑剔)air and strict rules. Who was this person I knew as my father, and who seemed sofriendly and interesting to be around? What had held him back before?The next day my dad pulled out his childhood pictures and told me quite a fewstories about his own childhood. Although our times together became easier over theyears, I never felt closer to him at that mome n t. After so many years, I’m at last seeing another side of my father. And in so doing, I’m delighted with my new friend. My dad in his new home in Arizona.46. Why did the author feel bitter about her father as a young adult?A .He was silent most of time B.

In The Future of Life, he takes us on a tour of the world’s natural resources. How are they used? What has been lost? What remains and is it able to continue with the presentspeed of use? Wilson also points out the need to understand fully the biodiversity(生物多样性) of our earth.Wilson begins with an open letter to the pioneer in environment protectionHenry David Thoreau. He compares today’s Walden Pond with that of Thoreau’s day. Wilson will use such comparisons for the rest of the book. The problem is clean manhas done great damages to his home over the years. Can the earth, with human help,be made to return to biodiversity levels that will be able to support us in the future?Biodiversity, Wilson argues, is the key to setting many problems the earth facestoday. Even our agricultural crops can gain advantages from it. Only a hundredspecies are the basis of our food supply, of which but twenty carry the load. Wilsonsuggests changing this situation by looking into ten thousand species that could bemade use of, which will be a way to reduce the clearing of the natural homes of plantsand animals to enlarge farming areas.At the end of the book, Wilson discusses the importance of human values inconsidering the environment. If you are to continue to live on the earth, you may wellread and act on the ideas.50. We learn from the text that Wilson cares most about_.A. the environment for plantsB. the biodiversity of our earthC. the waste of natural resourcesD. the importance of human values51.

We can infer that the text is _A. a description of natural resourcesB. a research reportC. a book reviewD. an introduction to a scientistC-class, a scientific study of the The Queen’s English is now sounding less upperQueen’s Christmas broadcasts had found. Researchers have studied each of hermessages to the Commonwealth countries since 1952 to find out the change in her pronunciation from the noble Upper Received to the Standard Received.Jonathan Harrington, a professor at Germany’s University of Munich, wanted to discover whether accent changes recorded over the past half century would take placewithin one person. “As far as I know, there just is nobody else for whom there is thissort of broadcast records,” he said.He said the noble way of pronouncing vowel(元音)had gradually lost ground asthe noble upper-c lass accent over the past years. “Her accent sounds slightly lessnoble than it did 50 years ago. But these are very, very small and slow changes thatwe don’t notice from year to year.”“We may be able to relate it to changes in the social classes,” he told The D Telegraph, a British newspaper. “In 1952 she would have been heard saying ‘thet in the bleck het’. Now it would be ‘that man in the black hat’. And ‘hame’ ra ‘home’. In the 1950s she would have been ‘lorst’, but by the 1970s ‘lost’.The Queen’s broadcast is a personal message to the Commonwealth countries.Each Christmas, the 10-minute broadcast is put on TV at 3pm in Britain as manyfamilies are recovering from their traditional turkey lunch.The results were published(发表) in the Journal of Phonetics._.54.

Which of the following is an example of a less noble accent in English?C. “hame”D. “lorst”A. “duaty” B. “citee” 56. We may infer from the text that the Journal of Phonetics is a magazine on _.A. speech soundsB. Christmas customsC. TV broadcastingD. personal messages57. What is the text mainly about?A. The relationship between accents and social classesB. The Queen’s Christmas speeches on TVC. The changes in a person’s accentD. The recent development of the English Language.DWhat makes a gift special? Is it the price you see on the gift receipt? Or is itthe look on the recipient’s face when they receive it that determines the true value? What gift is worth the most?This Christmas I was debating what to give my father. My dad is a hard personto buy for because he never wants anything. I pulled out my phone to read a textmessage from my mom saying that we were leaving for Christmas shopping for himwhen I came across a message on my phone that I had locked. The message was frommy father. My eyes fell on a photo of a flower taken in Wyoming, and underneath apoem by William Blake. The flower, a lone dandelion(蒲公英) standing against thebright blue sky, inspired me. My dad had been reciting those words to me since I wasa kid. That may even be the reason why I love writing. I decided that those wordswould be my gift to my father.I call back. I told my mom to go without me and that I already created my gift.I sent the photo of the cream-colored flower to my computer and typed the poem ontop of it. As I was arranging the details another poem came to mind. The poem waswritten by Edgar Allan Poe; my dad recited it as much as he did the other. I typed thatout as well and searched online for a background to the words of it. The poem wasfocused around dreaming, and after searching I found the perfect picture. The imagewas painted with blues and greens and purples, twisting together to create the themeand wonder of a dream. As I watched both poems passing through the printer, thewhite paper coloring with words that shaped my childhood, I felt that this was a giftthat my father would truly appreciate.Christmas soon arrive. The minute I saw the look on my dad’s face as he unwrapped those swirling black letters carefully placed in a cheap frame, I knew I hadgiven the perfect gift.58. The idea for a special gift began to form when the author was_.A. doing shoppingB. having a debateC. reading a messageD. leaving for Wyoming_.59. The author’s inspiration for the gift came fromA. a photo of a flowerB. a story about a kidC. a call from the motherD. a text about Christmas60. The underlined word “it” in Paragraph 3 refers to a poem by_.A. the fatherB. the authorC. William BlakeD. Edgar Allan Poe61. The author made the gift by _.A. searching for the poems onlineB. drawing the background by handC. painting the letters in three colorsD. matching the words with pictures62. What is the main purpose of the passage?A. to show how to design images for giftsB. to suggest making gifts from one’s heartC. to explain how computers help create giftsD. to describe the gifts the author has receivedE (Task- based reading)While it is impossible to live completely free of stress, it is possible to prevent stressas well as reduce its effect when it can’t be avoided. The US Department of Health and Human Services offers the following suggestions for ways to deal with stress.Try physical activity.When you are nervous, angry or upset, try releasing the pressure through exercise orphysical activity. Running, walking, playing tennis, or working in your garden are justsome of the activity you might try.Take care of yourself.You should make every effort to eat well and get enough rest. If you easily get angryand cannot sleep well enough, or if you’re not eating properly, it will be more likely that you will fall into stressful situation. If stress repeatedly keeps you from sleeping,you should consult a doctor.Make time for yourself.Schedule time for both work and entertainment. Don’t forget, play can be just asimportant to you over-all-well-being as work. You need a break just from your dailyroutine to just relax and have fun. Go window-shopping or work on a hobby. Allowyourself at least a half hour each day to do something you enjoy.Make a list of the things you need to do.Stress can result from disorganization and a feeling that “there’s so much to do, not enough time.” Trying to take care of everythingat once can be too much for youand as a result, you may not achieve anything.

2+4x ,配方得到抛物线的顶点坐标为(2,4),再计算出当x=1或3时,y=3,结合函数图象,利用抛物线y=-x 2+4x 与直线y=t 在1<x <3的范围内有公共点可确定t 的范围. 【详解】∵ 抛物线y=-x 2+mx 的对称轴为直线x=2,∴222(1)b m a -=-=⨯-, 解之:m=4, ∴y=-x 2+4x ,当x=2时,y=-4+8=4, ∴顶点坐标为(2,4),∵ 关于x

Can she come over tomorrow?” asked Donna, my 10-year-old daughter. Donna was very shy and I wanted her to make some friends to bring her out of her shell.“Sure, honey, that sounds great.” I said, thinking back to my own best friend, Lillian. We lived across the street from each other in Washington Heights, New York. We met at the age of 10, too. Like my daughter, I was shy, but Lillian drew me out. She was one of the friendliest people in school, with shiny black hair and a mile-wide smile. I knew we would be best friends forever.In senior high school, Lillian went on a trip to Florida. This was the first time we had to be away from each other for a few days. “I’ll be back soon.” she told me. But three days later, Lillian’s sister told me that she had fallen into a river and hadn’t come out any more. S oon, my family moved to New Jersey. Whenever I thought of her, tears came into my eyes.The next day Donna brought her new friend home. “Hi, Mrs. Loggia.” the little girl said. Her hair was so shiny and black and she shot me a big smile. “My name is Laura.”My daughter’s new friend was so much like Lillian. I was still puzzled (迷惑) when Laura’s mom came to pick her up later that afternoon. I opened the door to let her in. “Judy!” she cried. “It’s me, Lillian’s sister, from Washington Heights.” Y es, my daughter’s friend looked familiar.

It will make others laugh! The person’s not asking for your money, but your fingers.In the US, “give me five” or “give me the high five” is a popula r gesture. You can see it often in films or on TV. It means the slapping( 拍) of each other’s raised right hands together.People do it when they meet for the first time or something happy happens. For example, a student has good marks in exams or wins a lottery(彩票). If a football team wins game, the players will give high fives to everyone around to cerebrate.This gesture may come from the old Rome gesture of raising the right arm for the emperor (皇帝). This showed that the person raising his arm did not have a sword(剑) in his hand.1.”Give me five ” is a gesture to _______.A.make people laugh B.ask for moneyC.celebrate success D.search one’s pocket2.The gesture “give me five” is the slapping of ____.A.toes B.hands C.arms D.legs3.If someo ne _____, he WON’T show the gesture “give me five”.A.passes the exam B.wins a lotteryC.does well in a match D.wants to say goodbye4.The gesture started in ___ according to the storyA.Rome B.America C.China D.BritainC15、IQ scores have been measured(测量)since 1916, when Alfred Binet developed his intelligence list as follows:Some very famous people are known for their high IQ level. Jill St. John who has the highest score on this list was a major American film actress during the 1960’s and 1970’s. Jill was chosen to the University of California at the age of 14.Scientists have estimated(估算)the IQ scores that some famous historical people might have got. This was done by looking at their work and their ideas and the way they put them together. Leonardo da Vinci gets that high score not only for his art but also for his idea of the helicopter(直升飞机).Without modern scientific tools, he created a lot of design drawings and patterns, which was ahead of his time.1.When was the intelligence list developed?A.In 1970. B.In 1960.C.In 1917.

He was so well-known for his wide knowledge of almost everything that lots of people from all over the country came to learn things from him. The great man taught his studentswhole-heartedly and answered their questions with great patience.One day a student asked him, “My dear teacher, didn’t you say you yourself had many more questions about thingsthan we did? On the contrary, we students have far more than you.”With a smile, the teacher drew two circles—one as a big wheel, the other smaller.“Of course, I’ve learned much more. But a teacher does not necessarily have fewer questions than his students. Now look at these two circles. Within the big one is my knowledge of things, and within the smaller one is yours. Out of the circles is what is still unknown to us. Since mine is larger, the line that marks out the circle is longer. That means I have more opportunities to face what is still unknown. And that’s w hy I myself have more questions than you do. The more you learn, the more questions you have. Y ou never learn enough, you know.”根据材料内容选择最佳答案,并将其标号填入题前括号内。

It was the first time that my 31 took on a vivid form and acted as something important to start my training. As I grew older and was exposed to more, my interests in the world of dance 32 varied but that little girl’s dream of someday becoming a 33 in the company never left me. In the summer of 2005 when I was 18, I received the phone call which made that dream a 34;I became a member of the company dating back to 1925.As I look back on that day now, it surely 35 any sense of reality.

He moved there a few years ago, and I was eager to see his new place and meet his friends.My earliest memories of my father are of a tall, handsome, successful man devoted to his work and family but uncomfortable with his children. As a child I loved him; as a school girl and young adult, I feared him and felt bitter about him. He seemed unhappy with me unless I got straight A’s and unhappy with my boy friends if their fathers were not as “successful” as he was. Whenever I went out with him on weekends, I used to struggle to think up things to say, feeling on guard.On the first day of my visit, we went out with one of my father’s friends for lunch at an outdoor café. We walked along that afternoon, did some shopping andlaughed over my son’s funny facial expressions, gone with my father’s critical(挑剔) air and strict rules. Who was this person I knew as my father, and who seemed so friendly and interesting to be around? What had held him back before?The next day my dad pulled out his childhood pictures and told me quite a few stories about his own childhood. Although our times together became easier over the years, I never felt closer to him at that mome nt. After so many years, I’m at last seeing another side of my father. And in so doing, I’m delighted with my new friend. My dad in his new home in Arizona.46. Why did the author feel bitter about her father as a young adult?A .He was silent most of time B. He was too proud of himselfC. He did not love his childrenD. He expected too much of her47. When the author went out with her father on weekends, she would feel_.A. nervousB. sorryC. tiredD. safe48. What does the author think of her father after her visit to Tucson?A. More criticalB. More talkativeC. Gentle and friendlyD. Strict and hard-working49. The underlined words “my new friend” in the last paragraph refer to_.A. the author’s sonB. the author’s fatherC. the friend of the author’s fatherD. the café ownerBEdward Wilson is America’s, if not the world’s, leading naturalist. In The Future of Life, he takes us on a tour of the world’s natural resources. How are they used? What has been lost? What remains and is it able to continue with the present speed of use? Wilson also points out the need to understand fully the biodiversity(生物多样性) of our earth.Wilson begins with an open letter to the pioneer in environment protection Henry David T horeau. He compares today’s Walden Pond with that of Thoreau’s day. Wilson will use such comparisons for the rest of the book. The problem is clean man has done great damages to his home over the years. Can the earth, with human help, be made to return to biodiversity levels that will be able to support us in the future?Biodiversity, Wilson argues, is the key to setting many problems the earth faces today. Even our agricultural crops can gain advantages from it. Only a hundred species are the basis of our food supply, of which but twenty carry the load. Wilson suggests changing this situation by looking into ten thousand species that could be made use of, which will be a way to reduce the clearing of the natural homes of plants and animals to enlarge farming areas.At the end of the book, Wilson discusses the importance of human values in considering the environment. If you are to continue to live on the earth, you may well read and act on the ideas.50. We learn from the text that Wilson cares most about_.A. the environment for plantsB. the biodiversity of our earthC. the waste of natural resourcesD. the importance of human values51. How many species are most important to our present food supply?A. TwentyB. EightyC. One hundredD. ten thousand52. Wilson suggests that one way to keep biodiversity is to _A. learn how to farm scientificallyB. build homes for some dying speciesC. make it clear what to eatD. use more species for food53. We can infer that the text is _A. a description of natural resourcesB. a research reportC. a book reviewD. an introduction to a scientistCThe Queen’s English is now sounding less upper-class, a scientific study of the Queen’s Christmas broadcasts had found. Researchers have studi ed each of her messages to the Commonwealth countries since 1952 to find out the change in her pronunciation from the noble Upper Received to the Standard Received.Jonathan Harrington, a professor at Germany’s University of Munich, wanted to discover whether accent changes recorded over the past half century would take place within one person. “As far as I know, there just is nobody else for whom there is thissort of broadcast records,” he said.He said the noble way of pronouncing vowel(元音)had gradually lost ground as the noble upper-class accent over the past years. “Her accent sounds slightly less noble than it did 50 years ago. But these are very, very small and slow changes that we don’t notice from year to year.”“We may be able to relate it to changes in the social classes,” he told The Daily Telegraph, a British newspaper. “In 1952 she would have been heard saying ‘thet men in the bleck het’. Now it would be ‘that man in the black hat’. And ‘hame’ rather than ‘home’.

Or is itthe look on the recipient’s face when they receive it that determines the true value? What gift is worth the most?This Christmas I was debating what to give my father. My dad is a hard person to buy for because he never wants anything. I pulled out my phone to read a text message from my mom saying that we were leaving for Christmas shopping for him when I came across a message on my phone that I had locked. The message was from my father. My eyes fell on a photo of a flower taken in Wyoming, and underneath a poem by William Blake. The flower, a lone dandelion(蒲公英) standing against the bright blue sky, inspired me. My dad had been reciting those words to me since I was a kid. That may even be the reason why I love writing. I decided that those words would be my gift to my father.I call back. I told my mom to go without me and that I already created my gift.I sent the photo of the cream-colored flower to my computer and typed the poem on top of it. As I was arranging the details another poem came to mind. The poem was written by Edgar Allan Poe; my dad recited it as much as he did the other. I typed that out as well and searched online for a background to the words of it. The poem was focused around dreaming, and after searching I found the perfect picture. The image was painted with blues and greens and purples, twisting together to create the theme and wonder of a dream. As I watched both poems passing through the printer, the white paper coloring with words that shaped my childhood, I felt that this was a gift that my father would truly appreciate.Christmas soon arrive. The minute I saw the look on my dad’s face as he unwrapped those swirling black letters carefully placed in a cheap frame, I knew I had given the perfect gift.58.

The US Department of Health and Human Services offers the following suggestions for ways to deal with stress. Try physical activity.When you are nervous, angry or upset, try releasing the pressure through exercise or physical activity. Running, walking, playing tennis, or working in your garden are just some of the activity you might try.Take care of yourself.You should make every effort to eat well and get enough rest. If you easily get angry and cannot sleep well enough, or if you’re not eating properly, it will be more likely that you will fall into stressful situation. If stress repeatedly keeps you from sleeping, you should consult a doctor.Make time for yourself.Schedule time for both work and entertainment. Don’t forget, play can be just as important to you over-all-well-being as work. You need a break just from your daily routine to just relax and have fun. Go window-shopping or work on a hobby. Allowyourself at least a half hour each day to do something you enjoy.Make a list of the things you need to do.Stress can result from disorganization and a feeling that “there’s so much to do, and not enough time.” Trying to take care of everything at once can be too much for you and as a result, you may not achieve anything.
