k＜a k+1（k≥1），因为函数f（x）在区间（0，+∞）上单调递增，∴f（a k+1）＞f（a k），即得a k+2＞a k+1＞0，由数学归纳法原理知，a n+1＞a n对于一切正整数n都成立，∴数列{a n}为递增数列．（2）由（1）知：当且仅当0＜a1＜a2，数列{a n}为递增数列，∴f（a1）＞a1，即（a1为正整数），设（x≥1），则，∴函数g（x）在区间上递增，由于，g（6）=ln6＞0，又a1为正整数，∴首项a1的最小值为6．【点评】本题考查导数的运用：求单调区间，同时考查函数的零点存在定理和数学归纳法的运用，考查运算能力，属于中档题．选做题：本题设有（1）（2）（3）三个选考题，每题7分，请考生任选2题作答，满分7分．如果多做，则按所做的前两题计分．【选修4-2：矩阵与变换】20．【答案】（1）60N

Walking together, my father and I used to have a lot of conversations through which I learned lessons from his experience.He always told me,“You should have goals like climbing the mountain.“Without themountain-climbing that we both enjoyed, we couldn’t have enough time to spend together because my father was very busy. I really got a lot from the mountain-climbing. It gave me time to talk with my father and to be in deep thought as well as develop my patience.Once we climbed a very high mountain. It was so challenging for me because I was only ten years old. During the first few hours of climbing, I enjoyed the flowers and trees, and the birds’ singing. But as time passed, I got a pain in both of my legs. I wanted to quit climbing, but my father said to me,“ You can always see a beautiful sky at the top of the mountain, but you can’t see it before you reach the top. Only there can you see all of the nice things, which are just like your life.”At that time, I was too young to understand his words. But later after that, I got to know the meaning of hope in life. I found myself standing at the top of the mountain, and the sky was as clear as crystal.() 51. The passage tells us that mountain-climbing was ____ for the father and the son.A. hardB. enjoyableC. painfulD. comfortable() 52. The underline word“ crystal” in the passage means“ ____”A.岩石B.火焰C.水晶D.寒冷() 53. Which of the following is the closest in meaning to the father’s words in the second paragraph?A. You will get all you need at the top of the mountain.B. The sky is always as clear as crystal.C. You can find life is full of nice things.D. Never give up half-way.() 54. We can infer推断from the last paragraph that ________.A. the writer was very successful in his lifeB. the writer reached the top of the mountainC. though the writer was young, he could understand his fatherD. the writer used to stop half-way when he climbed the mountain() 55. The best title for the passage is __________.A. Reaching the Top of the MountainB. Standing at the Top of the MountainC. Conversations Between Father and SonD. How to Get to the Top of the MountainPassage B.Anger is a kind of feeling. Many things can make you angry. When your teacher gives you toomuch homework, when your team loses an important game, when a friend borrows your favorite thing and thin breaks it, you may get really angry.Usually, your body will tell you when you are angry. For example, you breathe faster, your faceturns red, and you may want to break something or hit someone, but sometimes, you hide your anger. For example, you may hide it in your heart. The problem is that if you do this, you may get a headacheor your stomach may hurt.In fact, it’s not good to hide your anger, and it’s normal for you to get angry sometimes, But anger must be let out in the right way, without hurting others or yourself.When you get angry, you can talk about it with other people. It’s helpful to talk about your angerwith an adult, such as parents, a teacher, etc. When you talk about anger, those bad feelings can start to go away. Here are some other things you can do when you start to feel anger: talk to a good friend; count from 1 to 100; give someone a hug; go for a bike ride; think about good things, etc.Remember that how you act when you are angry can make everything better or worse. Don’t letyour anger control you.() 56. You may not get angry when _____________,A. there is too much homework on this weekend.B. your favorite basketball team wins the gameC. a friend breaks your favorite thingD. your parents don’t let you watch TV() 57. _____ shows that you’re not angry.A.

The underlined word” control” in the last paragraph mean _____ in Chinese.A.控制B.连接C.帮助D.失去() 60. This passage is mainly about ________.A. angerB. excitementC. happinessD. sadnessPassage CWhen I was growing, I had an old neighbor called Dr. Smith. He didn’t look like any other doctor I’d ever known.He was a very kind person. After he retired, he began to plant trees in his large garden. He wished to make it a forest.The good doctor had some interesting ideas about planting trees. He never watered his new trees. Once I asked why. He said,“ If you water them, each baby tree will grow weaker and weaker. Otherwise, they will have to grow deep roots根to look for water under the earth by themselves.”He planted some oaks, and instead of watering them every morning, he beat them with a rolled-up newspaper.I asked him why he did that, and he said it was to get the tree’s attention.Dr. Smith died three years after I left home. I walked by his house and looked at the trees that I’d watched him plant about twenty years ago. They’re very big and strong now.I also planted some trees a few years ago and I carried water to them for a whole summer. However, after two years of caring too much, whenever a cold wind blows in, they shake a lot.Life is hard, whether we want it to be or not.

Nadia would not reply to anything Kate said. Kate was in charge of showing Nadia around on her first day at Buckminster Grade School. Kate could not figure out why the school had put out Nadia in a class where she could not understand what people were saying."Why did they do this? " Kate wondered aloud. "I mean, you can't learn if you can't understand the teacher."Nadia's voice was a whisper. "I understand English. I will learn." Nadia's English was perfect.Kate was TAL#NBSP perplexed. She couldn't understand why Nadia did not like to speak. Then she realized that moving to a new country probably wasn't the easiest thing to do. There were hundreds of unfamiliar and unusual things to learn—all at the same time."There're a lot of new things to learn, huh? " said Kate.Nadia nodded rapidly. In a quiet voice she replied. "Many things people say, I do not understand I have been speaking English and Romanian all my life, but I do not know what some children are saying. For example yesterday a boy asked if I could help him find the USB port on a thin black box he was carrying. Isn't a port a place for ships? It made no sense to me.""Don't worry." said Kate. "You'll figure everything out in time. You see, that thin black box was a computer. A USB port is a place where you can connect other machines to a computer."Nadia and Kate were quiet after that. They took notes while the teacher gave a maths lesson. To Kate's surprise, Nadia put up her hand and offered to answer questions at the blackboard.Nadia handled every question the teacher gave her. Some of the questions were really difficult, and no one understood what was going on except Nadia and the teacher. When the teacher said that Nadia answered everything correctly, the whole class clapped their hands.Nadia was smiling when she sat back down next to Kate.

But early horses weren't tame（驯服的） enough to perform these kinds of tasks. Scientists think the first interactions humans had with horses were far different from those today.Thousands of years ago, people killed the wild horses that lived around them for food. Over time, people began to catch the animals and raise them. This was the first step in domestication.As people began to tame and ride horses, they chose to keep those animals that had more desirable characteristics. For example, people may have chosen to keep horses that had a gentle personality so they could be ridden more easily. People who used horses to pull heavy loads would have chosen to keep stronger animals. Characteristics like strength are partly controlled by the animals' genes. So as the domesticated horses reproduced, they passed the characteristics on to their young. Each new generation of houses would show more of these chosen characteristics.Modern day horse breeds come in a wide variety of shapes and sizes. This variety didn't exist in the horse population before domestication. The Shetland horse is one of the smallest breeds—typically reaching only one meter tall. With short, strong legs, the animals were bred to pull coal out of mine shafts （矿井） with low ceilings. Huge horses like the Clydesdale came on the scene around 1700. People bred these heavy, tall horses to pull large vehicles used for carrying heavy loads.The domestication of horses has had great effects on societies. For example, horses were important tools in the advancement of modern agriculture. Using them to pull ploughs and carry heavy loads allowed people to farm more efficiently. Before they were able to ride horses, humans had to cross land on foot. Riding horses allowed people to travel far greater distance in much less time. That encouraged populations living in different areas to interact with one another. The new form of rapid transportation helped cultures spread around the world.(1) Before domestication horses were.A. caught for sportsB. hunted for foodC. made to pull ploughsD. used to carry people(2) The author uses the Shetland horse as an example to show.A. it is smaller than the Clydesdale horseB. horse used to have gentle personalitiesC. some horses have better shaped than othersD. horses were of less variety before domestication(3) Horses contributed to the spread of culture by.A. carrying heavy loadsB. changing farming methodsC. serving as a means of transportD. advancing agriculture in different areas(4) The passage is mainly about.A. why humans domesticated horsesB. how humans and horses needed each otherC. why horses came in different shapes and sizesD. how human societies and horses influenced each other20、【来源】 2018年北京海淀区北方交通大学附属中学高三三模第67~70题8分2015年北京东城区高三一模（D篇）第20题It is easy to lose patience with science today. The questions are pressing: How dangerous is air pollution? What about low-level radiation? When will that horrible earthquake strike California? And why can't we predict weather better? But the evidence is often described as "uncertain" , forcing scientists to base their points of view almost as much on intuition（直觉） as on science.When historians and philosophers of science listen to these questions, some conclude that science may not be able to solve all these problems any time soon. The unknowns can grow into riddles that are impossible to solve. Because of the unstable and changing state of the earth's atmosphere, for example, scientists have struggled for centuries to predict the weather with precision（精确）but failed.The case is different for scientists of astronomy. For example, they think that the gravitational force of a nearby space vehicle, though tiny, is able to change the path of a much larger planer if the vehicle spends enough time close to it. With the aid of Newton's law of gravitational attraction, ground controllers can predict the path of a planetary probe（探测仪）—or satellite—with incredible accuracy. They do this by calculating the gravitational force from each of the passing planers until the probe speeds beyond the edge of the solar system. A much more difficult task is to calculate what happens when two or three times of such force pill on the probe at the same time. Such procedures can, of course, be very difficult, but for experiments, they are effective.This range of questions — from simple problems to those impossibly complex — has resulted in nicknames for various fields of study: "soft" sciences and "hard" sciences. "Soft" sciences admit a great degree of uncertainty. Academicians tend to judge fields such as sociology, psychology, and political science as "soft" because they are assumed to be understandable, of unnecessary mathematical accuracy, and concerned with everyday affairs such as interpersonal relationships. However, "hard" sciences, such as astronomy and chemistry, are said to offer precise answers. Precise definitions for "hard" sciences vary, but the characteristics of "hard" sciences include: producing testable predictions; performing controlled experiments; relying on quantifiable data and mathematical models; a high degree of accuracy and objectivity; and generally applying a pure form of the scientific method.(1) We can learn from the passage that.A. a large planer is able to change the size of a tiny planetB. ground controllers can affect the gravitational force of planetsC. calculating the probe speeds beyond the solar system is possibleD. predicting the weather is more difficult than predicting the path of a satellite(2) According to the author, "soft" sciences.A. allow for certain inaccuracyB. focus on personal relationshipsC. are based on controlled experimentsD. are rooted in data and mathematical models(3) What might be the best title for the passage?A. Science, a Long History?B. Science and Its FunctionsC. Science, Accurate or Not?D. Science and Its Application(4) What is the author's attitude towards science in this passage?A. Objective.B. Skeptical.C. Disapproval.D. Optimistic.四、七选五21、【来源】 2018年北京海淀区北方交通大学附属中学高三三模第71~75题10分Direct banking transactions（交易）, cheques and payment cards came out in the 1950s and 60s. In the following decades, technological advancement saw the adoption of magnetic strips, pin entry technology and most recently contactless payments. With the developments of the Internet and modern smart phone technology, online purchases and online banking have reduced the role of cash.While the reality of a cashless society is a long way from being realized, many remain unwilling to see the use of cash decline or even disappear.1No doubt this same unwillingness was apparent when coinage made the switch from precious metals to non-precious metals.2The most powerful driving force for advancement and innovation in payment is convenience, and there is no denying that a cashless society is certainly a convenient society.Merchants, companies and organisations spend lots of time and money keeping track of their cash. And it takes resources and money to move it around, including security services to keep it protected. However, things are quite different in a cashless society.3Moreover, there is no need for expensive physical protection.For the average consumer, a cashless society would equally have convenience benefits. There would be no need to carry around a huge amount of cash or change. People would never worry about how much they have on them or when they will next need to make a withdrawal. The advantages are even greater for travelling as there is no need to exchange cash or carry around lots of money.4For example, if a thief steals your wallet all the cash can be taken and spent with case. However, if the wallet only contains cards, they can be easily and quickly cancelled, leaving the thief empty handed—reducing the motivation for the crime in the first place.5However, how do we define a cashless society? Is it a society that prefers not to use any physical money?A. However, with change come benefits.B. This is often due to deeply-rooted familiarity and fondness of using cash.C. And it is important that people understand the advantages of cashless society.D. They think the overall burden of processing physical cash is surprisingly high.E. Another driving force is security, something a cashless society would help to promote.F. While card and digital transactions still require verification(核实), the process is much smoother.G. Without doubt, payment cards and electronic payment processing methods provide numerous advantages.五、书面表达22、【来源】 2018年北京海淀区北方交通大学附属中学高三三模第76题15分假设你是红星中学高三学生李华。

increase blood pressure?Does it help you concentrate?However,coffee affects the health of the human population in other ways,too.Traditionally,coffee bushes are planted under the canopy(树荫) of taller trees.However,more and more farmers in Latin America are deforesting the land to grow full-sun coffee.At first,this increases production because more coffee bushes can be planted if there aren ’ny trees.With increased production come increased profits.Unfortunately,deforesting for coffee production immediately decreases the local wildlife habitat,because native birds nest and hide from predators捕(食者) on the tall trees and migrating birds rest there.Furthermore,in the long term,the full-sun method also damages the ecosystem because more chemical fertilizers and pesticides(杀虫剂) are needed to grow the coffee.The fertilizers and pesticides kill insects that eat coffee plants,and then the birds eat the poisoned insects and also die.The chemicals kill or sicken other animals as well,and can even enter the water that people will eventually drink.Fortunately,farmers in Central and South America are beginning to grow more coffee bushes in the shade.We can support these farmers by buying coffee with such labels as “sha rown ”a nd “bir-riendly ”.Sure,these varieties might cost a little more.But we g for the he’althreo einbirds,the land,ourselves,and the planet.I think it ’s
