n}中，a1=1，a4=8，∴，即8=q3，解得q=2，a7==1×26=64．故选：A．4．【分析】先根据已知循环条件和循环体判定循环的次数，然后根据运行的后s的值找出规律，从而得出结论．【解答】解：根据题意可知该循环体运行4次第一次：s=2，i=4＜10，第二次：s=8，i=6＜10，第三次：s=48，i=8＜10，第四次：s=384，s=10≥10，结束循环，输出结果S=384，故选：C．5．【分析】由约束条件作出可行域，数形结合得到最优解，联立方程组求出最优解的坐标，代入目标函数得答案．【解答】解：由约束条件，作出可行域如图，联立，解得：A(3，3)，化目标函数z=x+3y为y=-+，由图可知，当直线y=-+过A时，直线在y轴上的截距最大，z最大．此时z=3+3×3=12．故选：C．6．【分析】该几何体为正八面体，即两个全等的正四棱锥，棱长为1，棱锥的高为，即可求出体积．【解答】解：该几何体为正八面体，即两个全等的正四棱锥，棱长为1，棱锥的高为，所以，其体积为：2×（1×1）×=，故选：A．7．【分析】先把函数化成y=Asin(ωx+φ)的形式，再根据三角函数单调区间的求法可得答案．【解答】解：f（x）=sinwx+coswx=2sin(wx+)，(w＞0)．∵f(x)的图象与直线y=2的两个相邻交点的距离等于π，恰好是f(x)的一个周期，∴=π，w=2．F(x)=2sin(2x+)．故其单调增区间应满足2kπ-≤2x+≤2kπ+，k∈Z．kπ-≤x≤kπ+,,故选：C．8．【分析】由题意，可由函数的性质得出f(x)为[﹣1，0]上是减函数，再由函数的周期性即可得出f(x)为[3，4]上的减函数，由此证明充分性，再由f(x)为[3，4]上的减函数结合周期性即可得出f(x)为[﹣1，0]上是减函数，再由函数是偶函数即可得出f(x)为[0，1]上的增函数，由此证明必要性，即可得出正确选项．【解答】解：∵f(x)是定义在R上的偶函数，∴若f(x)为[0，1]上的增函数，则f(x)为[﹣1，0]上是减函数，又∵f(x)是定义在R上的以2为周期的函数，且[3，4]与[-1，0]相差两个周期，∴两区间上的单调性一致，所以可以得出f(x)为[3，4]上的减函数，故充分性成立．若f(x)为[3，4]上的减函数，同样由函数周期性可得出f(x)为[-1，0]上是减函数，再由函数是偶函数可得出f(x)为[0，1]上的增函数，故必要性成立．综上，“f(x)为[0，1]上的增函数”是“f(x)为[3，4]上的减函数”的充要条件．故选：D．9．【分析】根据题意，得出•=0，⊥；求出||=，利用平面向量数量积的夹角公式求出夹角的大小．【解答】解：非零向量满足，∴=，∴•=0，∴⊥；画出图形如图所示；∴||=，∴(+)•(-)=-=12-=-2，∴cos＜+，-＞===-，∴与的夹角为．故选：C．10．【分析】渐近线方程y=±2x，当过焦点的两条直线与两条渐近线平行时，这两条直线与双曲线右支分别只有一个交点，由此能求出此直线的斜率的取值范围．【解答】解：双曲线的渐近线方程y=±2x，当过焦点的两条直线与两条渐近线平行时，这两条直线与双曲线右支分别只有一个交点（因为双曲线正在与渐近线无限接近中），那么在斜率是[-2，2]两条直线之间的所有直线中，都与双曲线右支只有一个交点．此直线的斜率的取值范围[-2，2]．故选：D．11．【分析】设球心为O，求出AD=2，BD=2，设AC∩BD=E，则BE=，OP=OB=R，设OE=x，则OB2=BE2+OE2=2+x2，过O作线段OH⊥平面PAD于H点，H是垂足，PO2=OH2+PH2=1+(-x)2，由此能求出球半径R，由此能求出此球的表面积．【解答】解：设球心为O，如图，∵△PAD所在平面与矩形ABCD所在平面互相垂直，PA=PD=AB=2，∠APD=60°，∴AD=2，BD==2，设AC∩BD=E，则BE=，∵点P，A，B，C，D都在同一个球面上，∴OP=OB=R，设OE=x，在Rt△BOE中，OB2=BE2+OE2=2+x2，过O作线段OH⊥平面PAD于H点，H是垂足，∵O点到面PAD的距离与点E到平面PAD的距离相等，∴OH=1，∴在Rt△POH中，PO2=OH2+PH2=1+(-x)2=x2-2+4，∴2+x2=x2-2+4，解得x=，∴R=，∴此球的表面积S=4πR2=4π×=．故选：B．12．【分析】设M(x，y)，由⇒cx+by=c2，…①，由，cy-bx=bc…②由①②得x=，y=，…③把③代入椭圆得a4c2+4c6=a6⇒2c3=b3+bc2，c3-b3=bc2-c3，⇒(c-b）(b2+bc+2c2)=0⇒b=c．【解答】解：设M(x，y)，∵∴，⇒⇒即OA⊥MF⇒cx+by=c2，…①，因为，共线，cy-bx=bc…②由①②得x=，y=，…③把③代入椭圆得a4c2+4c6=a6⇒2c3=b3+bc2，c3-b3=bc2-c3，⇒(c-b)(b2+bc+2c2)=0⇒b=c⇒a=，椭圆的离心率e=．故选：A．二、填空题13．【分析】利用等差数列通项公式直接求解．【解答】解：∵等差数列{a n}的前n项和为S n，a1+a13=4，∴S13==．故答案为：26．14．【分析】先求出成绩在[16，18]的学生的频率，由此能求出成绩在[16，18]的学生人数．【解答】解：频率分布直方图中，从左到右的5个小矩形的面积之比为1：3：7：6：3，∴成绩在[16，18]的学生的频率为：=0.45，∴成绩在[16，18]的学生人数是：480×0.45=216．故答案为：216．15．【分析】根据题意，依据题意中“除k取余法”的算法，分析可得89=12×7+5，12=1×7+5，1=0×7+1，则有89=155(7)，即可得答案．【解答】解：根据题意，89=12×7+5，12=1×7+5，1=0×7+1，则89=155(7)，即89化为七进制数为155(7)，故答案为：155(7)．16．【分析】关于x的不等式(e x-a)x-e x+2a＜0可化为(x-1)e x＜a(x-2)；设f(x)=(x-1)e x，g(x)=a(x-2)，其中a＜；利用导数判断单调性、求出f(x)的最值，画出f(x)、g(x)的图象，结合图象得出不等式的解集中有且只有两个整数时a的取值范围．【解答】解：当a时，关于x的不等式(e x-a)x-e x+2a＜0可化为e x(x-1)-a(x-2)＜0，即(x-1）e x＜a(x-2)；设f(x)=(x-1)e x，g(x)=a(x-2)，其中a＜；∴f′(x)=e x+(x-1)e x=xe x，令f′(x)=0，解得x=0；∴x＞0时，f′(x)＞0，f(x)单调递增；x＜0时，f′(x)＜0，f(x)单调递减；∴x=0时f(x)取得最小值为f(0)=-1；g(x)=a(x-2)是过定点(2，0)的直线；画出f(x)、g(x)的图象如图所示；要使不等式的解集中有且只有两个整数值，∵a＜，当x=0时y=-1，满足条件，0是整数解；当x=-1时，f(-1)=-2e-1；当x=-2时，f(x)=-3e-2，此时=＞a，不等式有两个整数解为-1和0，∴实数a的取值范围是(，)．故答案为：(，）．三、解答题17．【分析】（Ⅰ）根据题意，由正弦定理可以将(c-2a)cosB+bcosC=0整理变形可得2sinA•cosB=sinC•cosB+sinBcosC，又由三角函数的和差公式可得2sinA•cosB=sin(B+C)，进而可得2sinA•cosB=sinA，即cosB=，由B的范围可得B的值．（Ⅱ）根据题意，由正弦定理可得b的值，同时可得a+c=2(sinA+sinC)，由三角函数的和差公式变形可得a+c=2sin(C+)，结合C的范围，计算可得a+c的范围，由b的值，即可得答案．18．【分析】（Ⅰ）根据数表，计算对应的概率值即可；（Ⅱ）根据数表，计算观测值，对照临界值表即可得出结论．19．【分析】（Ⅰ）连结AF交BE于O，则O为AF中点，设G为AC中点，连结OG，DG，推导出四边形DEOG为平行四边形，则BE∥DG，由此能证明BE∥平面ACD．（Ⅱ）点C到平面ACD的距离和点F到平面ACD的距离相等，均为2，从而三棱锥的B-ACD体积V

2017年黑龙江哈尔滨高三三模英语试卷-学生用卷
2017年黑龙江哈尔滨高三三模英语试卷-学生用卷一、阅读理解（共15小题，每小题2分，共30分）1、【来源】 2017年黑龙江哈尔滨高三三模（A篇）第21~24题8分Guide dogs enjoy their work very much, and they get a lot of satisfaction from a job well done, but there is no room for typical dog fun during the work day. Games, treats andpraise TAL#NBSP distract the dog from helping its handler navigate （指引方向）the course. Even when the handler doesn't need assistance, a guide dog on the job is trained to ignore distractions and keep still. This is because a guide dog must be able to come to handler's workplace or be in public places without creating a disturbance（干扰）.When you see a guide dog on the job, it is extremely important that you recognize that it is at work. Petting or talking to the dog spreads its concentration, which weakens the handler's ability to get around in his or her surroundings. People are very impressed with guide dogs and so we have a natural inclination （倾向） to praise them, but the best thing you can do to help a guide dog is to leave it alone so that it can pay attention to its surroundings and maintain its focus on its handler. Guiding is very complicated, and it requires a dog's undivided attention.When a guide dog gets home at the end of the day, however, it will play and soak up praise just like an ordinary pet. Guide dogs make the difference between work and play based on their lead harness（牵狗用的皮带）: When the harness is on, they must stay completely focused—when it comes off, it's playtime. Guide dogs work very hard every day, but they lead extremely happy lives, full of lots of attention and stimulation.Working as a guide dog requires good physical and mental shape, so guide dogs typically retire just before they enter old age. Retirement is usually at age 8 or 10; but some work for a little longer, and some guide dogs retire earlier if they're having trouble with the work.(1) What do you think is the typical job of a guide dog?A. Help the policemen to search for the murderer.B. Help the blind or weak-sighted people get around.C. Help the doctor to save the injured people.D. Help the owner to watch their house.(2) What does the writer want to tell the readers through the passage?A. Guide dogs are so helpful that we should make friends with them.B. Guide dogs are different from other dogs and they have some special talents.C. Guide dogs' life style and job situation.D. Guide dogs' trained way by their handlers.(3) What does the underlined word "distract" mean in the passage?A. to stop the dog paying attention to what he is doingB. to make the dog think very carefully about what he is doingC. to interrupt the dog so that he cannot do the work wellD. to stop the dog from doing something(4) What should you do when meeting with a guide dog at its job?A. Praise it.B. Feed it.C. Play with it.D. Leave it alone.2、【来源】 2017年黑龙江哈尔滨高三三模第25~28题8分2018~2019学年吉林长春朝阳区长春外国语学校高二上学期期中第11题6分Griffith Observatory （天文台） is a national leader in public astronomy, and one of the most popular attractions in Los Angeles.

Recently, a virus called Ebola has reappeared in Guinea, killing 62 people so far. It leads to high fever, bleeding and so on. Ebola can kill 90% of those infected（感染）, especially in underdeveloped societies like those in Africa.Ebola is named after the Ebola River, where it was first discovered in 1976. There are five different types of the Ebola virus, each named after where they first happened: Sudan, Ivory Coast, Reston, Bundibugyo, and Zaire. The deadliest of the five, Zaire, was responsible for the 2012 outbreak, and is believed to be attacking Guinea.Ebola is naturally found in fruit bats, which pass on the virus to other animals by biting or sucking on their blood. Humans who are suffering from the Ebola infection might have touched the bodily fluids（体液） of the infected animals. Once infected, a human becomes a carrier of the deadly virus.Since we live in an interconnected world, where the situation in one country can affect us all, the effects of Ebola are huge: damaging trade relations, affecting foreign visitors, and weakening entire countries. Already the Guinea virus is spreading fast with a few cases spotted in Conakry—the capital city of Guinea, far away from the origin of the virus. It is feared that the disease may have already reached neighboring Liberia and Sierra Leone, too.Unfortunately, there are no disease-specific treatments for Ebola. Healthcare workers only supply the infected people with water to keep them in good condition. Since there have been many cases of nurses catching the disease from patients, they are forced to wear strict protective clothes, and in some cases, not even allowed to get close to the infected. The fact that there is no cure for the Ebola virus is what makes the outbreak a challenging one to control.(1) From the text we know that.A. Ebola is naturally found in fruitB. Ebola is a highly infectious virusC. Ebola is a newly discovered diseaseD. Ebola is recently controlled in Guinea(2) What is Paragraph 4 mainly about?A. The causes of Ebola.B. The origin of Ebola.C. The treatment for Ebola.D. The influences of Ebola.(3) In Ebola infected areas, healthcare workers.A. face the danger of catching virusB. take measures to protect the nursesC. give water and medicine to the patientsD. do whatever they can to save the infected(4) The text probably comes from.A. an English newspaperB. a tourist guideC. a safety brochureD. a medical report4、【来源】 2017年黑龙江哈尔滨高三三模（D篇）第33~35题6分There is an English saying: " Laughter is the best medicine." Until recently, few people took the saying very seriously. Now however, doctors have begun to study laughter and the effects it has on the human body. They have found facts that laughter really can improve people's health.Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their heart rate, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise. It increases blood pressure, the heart rate and the rate of breathing; it also works several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial.Other tests have shown that laughter appears to be able to reducing the effect of pain on the body. In one experiment doctors produce pain on the body. In one experiment doctors produce pain in groups of students who listened to different radio programs. The group which tolerated（忍受） the pain for the longest time was the groups which listened to a funny program. The reason why laughter can reduce pain seems to be that it helps to produce endorphins in the brain. These are natural chemicals which diminish both stress and pain.There is also some fact to suggest that laughter helps the body's immune system, that is, the system which fights infection. In an experiment, one group of students watched a funny video while another group of students served as the control group ---- in other words, a group with which to compare the first group. Doctors checked the blood of the students in both groups and found that the people in the group that watch the video had an increase in the activity of their white blood cells, that is, the cells which fight infection.As a result of these discoveries, some doctors and psychiatrists in the United States now hold laughter clinics, in which they try to improve their patients' condition by encouraging them to laugh.They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.(1) It can be learnt from the passage that laughter can.A. make people feel youngerB. change people's habitsC. improve peoples healthD. make people love their lives(2) Smiling can produce.A. more effects than laughterB. the same effects as laughterC. less effects on the human bodyD. no effects on the human body(3) The main idea of this passage is that.A. there are several ways of studying the benefits of laughterB. laughter and physical exercise have the same effects on human bodyC. the doctors should learn how to make people laughD. tests show that laughter can produce beneficial effects on human body二、七选五（共5小题，每小题2分，共10分）5、【来源】 2017年黑龙江哈尔滨高三三模第36~40题10分Think for a moment about the teachers you've had at junior or senior high school. Which one did you like best? And why? Were the teachers you liked best also the ones who were the best teachers, in your opinion?1And then begin to read further.Some very common answers to this question are that teachers need to love their students, that they need to have expert knowledge of their subjects and that they should devote themselves completely to their work. All of these ideas are, of course, true to a certain extent.2It's impossible for anyone to love everyone he knows, and teachers deal with a very large number of students over the years. On the other hand, teachers should certainly be able to make their students feel that they're interested in them as people.3 A deep knowledge of the subject is especially important.4That's to say, a teacher needs to be trained in the skills of teaching. These skills include how to control a class. Finally, teachers have to devote a lot of time and energy to their work, of course. However, because they're also models that their students must follow, it's important that they should be well-balanced people with interests outside their school work—families, friends, hobbies, etc.5A. They're perhaps a little too simple.B. Students ask too much from teachers.C. Well-qualified teachers should be educated and capable.D. Consider for a minute the qualities that make a teacher outstanding.E. A teacher who only lives for work is likely to become narrow-minded.F. Equally important is the ability to pass that knowledge on to the students effectively.G. They also pay attention to the development of both their brains and their characters.三、完形填空（共20小题，每小题1.5分，共30分）6、【来源】 2017年黑龙江哈尔滨高三三模第41~60题30分About 10 years ago I was having my annual party and my niece came to see me.

第二部分：阅读理解（共两节，满分40分） 第一节：（共15小题；每小题2分，满分30 分） 阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项，并在答题卡上将该项涂黑。 A With fuel costs rising and airlines finding more fees to impose （强加，征税）on travelers every day, airfare isn’t getting any cheaper. Since you can’t drive to all your dream destinations, flying is the only way to go sometimes and, undeniably, the fastest. Luckily, there are plenty of ways to find the most affordable fares and also avoid paying as many extra charges as possible when you plan ahead. Get the best fare. Airlines put out their fare sales on Tuesday morning, making this day the best day to book a flight for less. Fly during the least popular times. Tuesday, Wednesday and Saturday are the slowest days to fly, which means cheaper deals than the rest of the week. You can also find reduced rates on early morning flights, since many people don’t like to get up before the sun to get to the airport. Earlier boarding times can also considerably cut down your chances of getting bumped on an overbooked flight or delayed because of other delayed flights or mechanical issues.
