时，该工业园区的面积最小，最小面积为15km 2．…………… 16分 （方法二）如图1，以A 为原点，AB 为x 轴，建立平面直角坐标系． 因为tan α＝－2，故直线AN 的方程是y ＝－2x ． 设点P (x 0，y 0)．因为点P 到AM 的距离为3，故y 0＝3． 由P 到直线AN 的距离为5， 得∣2x 0＋y 0∣5＝5，解得x 0＝1或x 0＝－4(舍去)， 所以点P (1，3)． ……………………………… 4分 显然直线BC 的斜率存在．设直线BC 的方程为y －3＝k (x －1)，k ∈(－2，0)． 令y ＝0得x B ＝1－3k． ……………………………… 6分由⎩⎨⎧y －3＝k (x －1)，y ＝－2x解得y C ＝6－2k k ＋2． ……………………………… 8分设△ABC 的面积为S ，则S ＝12⋅x B ⋅y C ＝－k 2＋6k －9k 2＋2k ＝－1＋8k －9k 2＋2k ． …………… 10分 令8k －9＝t ，则t ∈(－25，－9)，从而k ＝t ＋98．因此S ＝－1＋t (t ＋98)2＋2×t ＋98＝－1＋64t t 2＋34t ＋225＝－1＋6434＋t ＋225t ．……… 13分因为当t ∈(－25，－9)时，t ＋225t∈(－34，－30]， 当且仅当t ＝－15时，此时AB ＝5，34＋t ＋225t 的最大值为4．从而S 有最小值为15．答：当AB ＝5km 时，该工业园区的面积最小，最小面积为15km 2．…………… 16分 （方法三）如图2，过点P 作PE ⊥AM ，PF ⊥AN ，垂足为E 、F ，连接P A ．设AB ＝x ，AC ＝y ． 因为P 到AM ，AN 的距离分别为3，5， 即PE ＝3，PF ＝5．由S △ABC ＝S △ABP ＋S △APC＝12⋅x ⋅3＋12⋅y

2＋1．当x ＝1时，f (1)＝1，f ′(1)＝－2，所以函数y ＝f (x ) (x ∈[0，＋∞))的图象在x ＝1处的切线方程为y －1＝－2(x －1)， 即2x ＋y －3＝0． ………………………………………………… 3分 （2）f (x )＝g (x )即为ax 3＋|x －a |＝x 4．所以x 4－ax 3＝|x －a |，从而x 3(x －a )＝|x －a |．此方程等价于x ＝a 或⎩⎨⎧x ＞a ，x ＝1或⎩⎨⎧x ＜a ，x ＝－1． (6)分·AMNP B C（第19题图2）E F所以当a ≥1时，方程f (x )＝g (x )有两个不同的解a ，－1； 当－1＜a ＜1时，方程f (x )＝g (x )有三个不同的解a ，－1，1；当a ≤－1时，方程f (x )＝g (x )有两个不同的解a ，1． ………………………… 9分 （3）当a ＞0，x ∈(a ，＋∞)时，f (x )＝ax 3＋x －a ，f ′(x )＝3ax 2＋1＞0，所以函数f (x )在(a ，＋∞)上是增函数，且f (x )＞f (a )＝a 4＞0．所以当x ∈[a ，a ＋2]时，f (x )∈[f (a )，f (a ＋2)]，1024f (x )∈[1024f (a ＋2)，1024f (a )]，当x ∈[a ＋2，＋∞)时，f (x )∈[ f (a ＋2)，＋∞)． ………………………………… 11分 因为对任意的x 1∈[a ，a ＋2]，都存在x 2∈[a ＋2，＋∞)，使得f (x 1)f (x 2)＝1024， 所以[1024f (a ＋2)，1024f (a )]⊆[ f (a ＋2)，＋∞)． ……………………………………… 13分从而1024f (a ＋2)≥f (a ＋2)．所以f 2(a ＋2)≤1024，即f (a ＋2)≤32，也即a (a ＋2)3＋2≤32． 因为a ＞0，显然a ＝1满足，而a ≥2时，均不满足．所以满足条件的正整数a 的取值的集合为{1}． ……………………………… 16分宿迁市三校2016届高三年级学情调研卷数学附加题参考答案及评分标准

[Sample]To have her kittens stay in the proper place—attic, Puss tried several times but was always stopped by the servant. T hanks for a strange and kind cat’s help, she made it. (32words) I’m deeply moved by what the strange cat did. He helped Puss selflessly asking for nothing in return, which made me think of what happened to me recently. It was on Monday morning, when several teachers attended our English lesson. Among them, a middle-aged teacher sat beside me, leaving her wallet on my desk. But she forgot to take it after class. So I rushed out, gave it back to her and ran away.As far as I am concerned, the spirit of being ready to help others should be advocated. Helping others is a traditional virtue in China. If you help others today, maybe others will help you in the future. In this way, we can construct a harmonious society. (121words)听力原文Text1M: Welcome home, Mary!

It is known, in the business, as “hoisting”.But the hoisting game is not 38 it used to be. Even at the height of the sales, shoplifters today never know 39 they are being watched by one of those evil little balls that hang from the ceilings of so many department stores above the most desirable goods.As if that was not trouble enough for them, they can now be filmed 40 and obliged to attend a showing of their performance in court.Selfridges was the first big London store to install closed-circuit videotape equipment to watch its sales floors. In October last year the store won its first court 41 for shoplifting using an evidence of a videotape clearly showing a couple 42 dresses. It was an important test case which 43 other stores to install similar equipment.When the balls, called sputniks, first make a(n) 44 in shops, it was widely believed that their only function was to 45 shoplifters. Their 46 ridiculous appearances, the curious holes and red lights going on and off, certainly make the theory believable.It did not take long, 47 , for serious shoplifters to start showing suitable 48 . Soon after the equipment was 49 at Selfridges, store detective Brian Chadwick was sitting in the control room watching a woman 50 putting bottles of perfume into her bag.“As she turned to go,” Chadwick 51 , “she suddenly looked up at the …sputnik‟ and stopped. She could not 52 have seen that the camera was trained on her because it is completely hidden, but she 53 have had a feeling that I was looking at her.”“For a moment she paused, but then she 54 to counter and started putting everything 55 . When she had finished, she opened her bag towards the camera to show it was empty and hurried out of the store.”36. A. As B. With C. For D. Since37.

You‟d better try your best to speak. Don‟t be afraid of making mis takes. But be careful not to let them keep you from improving the language. While you are doing this, a good exercise is to write—keep a diary, write notes, letters or articles, then if you can, ask someone to go through what you have written and tell you where is wrong. Many mistakes in your speaking will be easily found when you write. Through correcting the mistakes, you can do better in learning a language.If you are slow in speaking, don‟t worry. One of the helpful ways is reading, either aloud or to yourself. The important thing is to choose something interesting to read. It can‟t be too difficult for you. When you are reading in this way, don‟t stop to look up the words if you can guess their meanings or if they have nothing important to do with the sentence. You can do that some other time.56.

The best title of this passage might be _________.A. How to Learn a Foreign LanguageB. How to Improve ReadingC. How to Learn WritingD. More Reading, Less SpeakingBWhen thinking about placing a human being in space, one of the most important questions was how to design special clothing needed to protect a person from the dangers of the space environment. The cold of space will freeze skin in a short time. The fierce heat of the sun can cause severe burns. The lack of atmosphere can cause gases in the body to expand and even burst. With no oxygen to breathe, a human being will die in only a few moments. Radiation from the sun is another risk in space. So is damage from small pieces of rock and objects like meteoroids (陨石).In 1933, an American flyer, Wiley Post, designed one of the first successful devices to protect a pilot at extreme heights. It was a large device that looked like a can surrounded the pilot's head. Astronauts in the American space agency (NASA) flew the first American space flights in the early 1960s. The clothing was similar to that invented by Wiley Post.Today, astronauts wear very different protective clothing. It lets them move, do useful tasks, and stay outside their spacecraft in comfort and safety for several hours. The spacesuit is called the shuttle extravehicular mobility unit or EMU. It was designed to endure longer and to permit more movement than earlier spacesuits.The EMU has a number of parts that an astronaut can link together by using only one hand, which makes it possible for each astronaut to select the parts that fit correctly.Nowadays, NASA scientists are also considering the kind of spacesuits that would be needed for exploration on the planet Mars. Because of the gravity on Mars, spacesuits may have to be designed to be lighter than suits used in orbit or on the moon. The equipment may also have to protect astronauts from dust carried in the winds on Mars. And, they must be easy to repair and keep clean during a longer flight to and from the red planet.59. Which of the following is NOT mentioned about the dangers of space environment?A. Lack of oxygen.B. Fierce heat from the sun.C. Gases in the body.D. Radiation from the sun.60. Which of the following statements is true, according to this passage?A. Wiley Post designed the first protective clothing for astronauts.B. Astronauts wearing earlier spacesuits had some difficulty in moving, doing useful tasks andso on.C. EMU has many parts that can be linked together by using two hands.D. Special spacesuits have been used for exploration of the planet Mars.61. The underlined word “endure” means _______.A. provideB. moveC. liveD. last62. The best title of the passage might be ______.A. Space explorationB. Astronauts‟ flightsC. The Advantages of SpacesuitsD. The Evolution of SpacesuitsCIn some urban centers, workholism is so common that people do not consider it unusual: they accept the lifestyle as normal. Government workers in Washington D. C., for example, frequently work sixty to seventy hours a week. They don‟t do this because they have to; they do it because the y want to.Workholism can be a serious problem. Because true workaholics (工作狂) would rather work than do anything else, they probably don‟t know how to relax.Is workholism always dangerous? Perhaps not. There are, certainly, people who work well under stress. Some studies show that many workaholics have great energy and interest in life. Their work is so pleasurable that they are actually very happy. For most workaholics, work and entertainment keep them busy and creative.Why do workaholics enjoy their jobs so much? There are several advantages to work. Of course, it provides people with paychecks, and this is important. But it offers more than financial security. It provides people with self-confidence; they have a feeling of satisfaction when they‟ve produced a cha llenging piece of work and are able to say, “I made that.” Psychologists claim that work gives people an identity through participation in work, they get a sense of self and individualism. In addition, most jobs provide people with a socially acceptable way to meet others. Perhaps some people are compulsive about their work, but their addiction seems to be a safe-even an advantageous-one.63. The passage indicates that workaholics ______.A. just know work but nothing elseB. find their work provide them more satisfaction and self-confidence than how much they arepaidC. are willing to work hard for long hours without payD. has the work with more responsibility than others64. One of the reasons that some people are not willing to quit their jobs even in their eighties and nineties is that ______.A. they are in the need of financial securityB. they long for a sense of identity and being accomplishedC. they would rather work than be disturbed by domestic affairsD. they may have health problems from sheer boresom65. This passage is mainly about ______.A. people who are absorbed in their work may enjoy movies, sports and other kinds ofentertainmentB. workaholics are usually successful people, but their lives are in a messC. workholism can lead to serious problems but it can also create a joyful lifeD. those who work even under difficult conditions may be very happy66. It can be inferred from the passage that ______.A. in the eyes of all the common people workaholics are peculiarB. workaholics are as addicted to their job as other people are to drugs or alcoholC. a piece of challenging work may provide the workaholics a sense of satisfactionD. to workaholics, work is the sole source of happinessDWhen I was young, I wished for a good car and a big house. That was my idea of success. I took all the advanced classes and tried to do well in the exams with my mind set on going to a key school. I just knew that I would somehow become famous and be able to afford the car and the dream house. All the way through junior years, my mind was planningthis beautiful future.Then in the eleventh grade, many losses changed my mind. First, one of my friends died at 16. Soon after, my great-grandmother passed away, followed by my beloved fourth-grade teacher. These events left me not knowing what to do or where to go. Death had never touched me so closely.After a long period of emptiness, it finally struck me: Life is not promised and neither is future success. Though I was attempting to achieve material success, I was not enjoying my daily life. I realized that finding inner peace, purpose and happiness will stick with me forever and that is real success.Enjoying life‟s precious quirks (偶发事件) makes an ordinary person more successful than a wealthy person who isn‟t content and takes everything for granted. The summer before senior years, my attitude changed greatly. Instead of memorizing facts, I began learning skills. Instead of focusing on the future, I focused on today and the many blessings and successes that came with it.I still get excellent grades, but now I devote weeks to studying instead of struggling for exams, and I think about the future with a deeper sense of meaning. For me, being successful means truly living life each day.67.

What does the author want to tell the readers?A. The true meaning of life.B. The true meaning of studying.C. How to achieve success.D. His opinion about success.70. According to the passage, which of the following is TRUE?A. The author thinks that success is not promised.B. His teacher died before the death of his great-grandpa.C. The author didn‟t do well in all the exams.D. He didn‟t want to take all the exams.第五部分；任务型阅读（共10小题；每小题1分，满分10分）Do you love traveling? If the answer is yes, then have you ever thought about why? You may maintain that traveling can help you expand your scope of knowledge, especially geographical and historical learning. It will provide more chances for you to enjoy food and try on clothes that you otherwise cannot possible have. A famous English author Francis Bacon (1561-1626) makes a point when he says that, “Travel, in the younger sort, is a part of education; in the elder, a part of experience.”Evidence of leisure travel can be traced as far back as ancient Babylon. This year, according to the World Travel & Tourism Council, the 1 billionth tourist will cross an international boundary before the end of this month. That means that one in seven people on the planet traveled this year,something that would not have been possible a few decades ago. Around 20 years ago only the rich could travel.While the US and France remain the two largest destinations for world travel, experts say much of the explosive growth in tourism has been to countries like Guatemala, the Dominican Republic, and the Ivory Coast, which weren‟t even on the world tourism map a decade ago. The top five destinations in the world, according to the United Nations World Tourism Organization, are Paris, London, New York, the Mediterranean, Turkey.Several factors have led to the boom in world travel. The prosperity (富裕) of people in Asia is one factor. People in Asian developing countries have lifted their incomes above middle-class levels in the past few years. And a lot of them have used their new wealth to travel. In addition, travel costs have been reduced thanks to the rapid development of transportation, and competition between airlines to give customers the best prices.第六部分书面表达 (满分25分)人们完成工作的方式通常有两种：独立完成和合作完成。
