M＝（）A．{x|﹣1＜x＜3}B．{x|x≤﹣1或x＞3}C．{x|x＜﹣1或x＞3}D．{x|x≤﹣1或x≥3}解：因为全集U＝R，集合M＝{x|﹣1＜x≤3}，所以∁R M＝{x|x≤﹣1或x＞3}．故选：B．2．函数f（x）=√4−x2x−1的定义域为（）A．[﹣2，2]B．（﹣2，3）C．[﹣2，1）∪（1，2]D．（﹣2，1）∪（1，2）解：要使函数有意义，须满足{4−x 2≥0x−1≠0，解得﹣2≤x≤2，且x≠1，故函数f（x）的定义域为[﹣2，1）∪（1，2]，故选：C．3．已知函数f（x）={f(x−1)，x＞−2x2+2x−3，x≤−2，则f（f（1））＝（）A．5B．0C．﹣3D．﹣4解：∵函数f（x）={f(x−1)，x＞−2 x2+2x−3，x≤−2，∴f（1）＝f（0）＝f（﹣1）＝f（﹣2）＝﹣3，∴f（f（1））＝f（﹣3）＝0．故选：B．4．不等式﹣3x2+7x﹣2＜0的解集为（）A．{x|13＜x＜2}B．{x|x＜13或x＞2}C．{x|−12＜x＜−13}D．{x|x＞2}解：由﹣3x2+7x﹣2＜0，得3x2﹣7x+2＞0，即（3x﹣1）（x﹣2）＞0，解得x＜13或x＞2，所以该不等式的解集为{x|x＜13或x＞2}．故选：B．5．已知函数是f （x ）定义在R 上的偶函数，则“f （x ）是（﹣∞，0）上的减函数”是“f （﹣2）＜f （4）”的（ ） A ．充分不必要条件 B ．必要不充分条件 C ．充要条件D ．既不充分也不必要条件解：因为f （x ）是偶函数，所以f （﹣4）＝f （4）．由f （x ）是（﹣∞，0）上的减函数，则f （﹣2）＜f （﹣4），即f （﹣2）＜f （4）； 反之，对于函数f(x)={x ，x ＞21|x|，−2≤x ≤2，且x ≠0−x ，x ＜−2，显然，f （x ）是偶函数，且f(−2)=12＜f （4）＝4，但是f （x ）不是（﹣∞，0）上的减函数． 故“f （x ）是（﹣∞，0）上的减函数”是“f （﹣2）＜f （4）”的充分不必要条件． 故选：A ．6．给出下列命题：①若a ＜b ，c ＜0，则c a ≤cb；②若ac ﹣3＞bc ﹣3，则a ＞b ；③若a ＞b 且k ∈N +，则a k ＞b k ；④若c ＞a ＞b ＞0，则ac−a＞b c−b．其中真命题的个数（ ）A ．1B ．2C ．3D ．4解：①中，因为a ＜b ，c ＜0，因为a ，b 的符号不定，所以1a，1b的大小关系不定， 所以ca，cb 的大小关系不定，所以①错；②中，ac ﹣3＞bc ﹣3，若c ＜0，则a ＜b ，所以②错；③中，若a ＞b 且k ∈N +，例如：a ＝﹣2，b ＝﹣3，k ＝2，此时a k ＜b k ，所以③错； ④中，若c ＞a ＞b ＞0，则0＜c ﹣a ＜c ﹣b ，1c−a＞1c−b＞0，又a ＞b ＞0，所以ac−a＞b c−b，所以④正确．所以只有1个命题正确． 故选：A ．7．已知函数f （x ）为R 上的奇函数，当x ≥0时，f （x ）＝x 2﹣2x ，则当x ＜0时，f （x ）的解析式为（ ） A ．﹣x 2﹣2x B ．﹣x 2+2x C ．x 2+2xD ．以上都不对解：根据题意，设x ＜0，则﹣x ＞0，函数f （x ）为R 上的奇函数，当x ≥0时，f （x ）＝x 2﹣2x ，则f （x ）＝﹣f （﹣x ）＝﹣[（﹣x ）2﹣2（﹣x ）]＝﹣（x 2+2x ）＝﹣x 2﹣2x ．8．已知函数f(x)={ax 2−2x −a ，x ≥1(a +3)x −1，x ＜1，任意x 1，x 2∈R ，x 1≠x 2，都有f(x 1)−f(x 2)x 1−x 2＜0，则实数a 的取值范围是（ ） A ．[﹣4，﹣3）B ．（﹣∞，﹣3）C ．[﹣4，0）D ．（﹣4，0）解：根据题意，任意x 1，x 2∈R ，x 1≠x 2，都有f(x 1)−f(x 2)x 1−x 2＜0，则f （x ）在R 上为减函数，又由函数f(x)={ax 2−2x −a ，x ≥1(a +3)x −1，x ＜1，则有{ a ＜01a ≤1a +3＜0a −2−a ≤a +3−1，解可得﹣4≤a ＜﹣3，即a 的取值范围为[﹣4，﹣3）． 故选：A ．二、多项选择题：本大题共4小题，每小题5分，共20分．在每小题给出的四个选项中，有多个选项是符合题目要求的，全部选对的得5分，选对但不全的得2分，有选错的得0分） 9．下列各组函数是同一函数的有（ ） A ．f(x)=x 3x与g （x ）＝x 2 B ．f （x

≠0}，g （x ）＝1的定义域为R ，故错误； 对于D ，f(x)=√1+x ×√1−x =√1−x 2定义域为[﹣1，1]， g(x)=√1−x 2定义域为[﹣1，1]，故正确． 故选：BD ．10．下列说法中正确的有（ ）A ．命题p ：∃x 0∈R ，x 02+2x 0+2＜0，则命题p 的否定是∀x ∈R ，x 2+2x +2≥0B ．“|x |＞|y |”是“x ＞y ”的必要条件C ．命题“∀x ∈Z ，x 2＞0”的是真命题D ．“m ＜0”是“关于x 的方程x 2﹣2x +m ＝0有一正一负根”的充要条件 解：对于A ，命题p 的否定是∀x ∈R ，x 2+2x +2≥0，故A 正确；对于B ，|x |＞|y |不能推出x ＞y ，例如|﹣2|＞|1|，但﹣2＜1；x ＞y 也不能推出|x |＞|y |，例如2＞﹣3，而|2|所以“|x |＞|y |”是“x ＞y ”的既不充分也不必要条件，故B 错误； 对于C ，当x ＝0时，x 2＝0，故C 错误；对于D ，关于x 的方程x 2﹣2x +m ＝0有一正一负根⇔{4−4m ＞0m ＜0⇔⇔m ＜0，所以“m ＜0”是“关于x 的方程x 2﹣2x +m ＝0有一正一负根”的充要条件，故D 正确． 故选：AD ．11．下列选项中正确的是（ ） A ．若正实数x ，y 满足x +2y ＝1，则2x +1y≥8B ．当x ≥2时，不等式x +4x+1的最小值为3C ．不等式a +b ≥2√ab 恒成立D ．存在实数a ，使得不等式a +1a≤2成立 解：对于A ，若正实数x ，y 满足x +2y ＝1，则2x+1y =(2x+1y)⋅(x +2y)=4+4y x+x y≥4+2√4y x⋅x y=8，当且仅当4y x=xy，即x =12，y =14时等号成立，故A 正确；对于B ，x ≥2时，x +1≥3，则有x +4x+1=x +1+4x+1−1≥2√(x +1)⋅4x+1−1=3， 当且仅当x +1=4x+1时，即x ＝1时等号成立，所以不等式x +4x+1的最小值不为3，故B 错误； 对于C ，不等式a +b ≥2√ab 恒成立的条件是a ≥0，b ≥0，比如取a ＝﹣1，b ＝﹣1时，不等式不成立，故C 错误；对于D ，取a ＝﹣1，不等式显然成立，故D 正确． 故选：AD ．12．已知函数f(x)=xx+1，则下列说法正确的是（ ） A ．f （x ）的定义域为{x |x ≠﹣1} B ．f （x ）的值域为RC ．f （x ）在区间（﹣1，+∞）上单调递增D ．f(1)+f(2)+f(3)+⋯+f(2023)+f(12)+f(13)+⋯+f(12023)的值为40452解：对于A ，由x +1≠0，得函数f(x)=x 的定义域为{x |x ≠﹣1}，A 正确；对于B ，由f(x)=x x+1=1−1x+1，得f （x ）≠1，即f （x ）的值域为（﹣∞，1）∪（1，+∞），B 错误； 对于C ，f （x ）在区间（﹣1，+∞）上单调递增，C 正确；对于D ，f(x)+f(1x )=x x+1+1x 1x +1=x x+1+1x+1=1，又f(1)=12，则f(1)+f(2)+f(3)+⋯+f(2023)+f(12)+f(13)+⋯+f(12023)=40452，D 正确． 故选：ACD ．三、填空题：本大题共4个小题，每小题5分，共20分．13．已知集合A ＝{x |3≤x ＜7}，B ＝{x |2＜x ＜10}，C ＝{x |x ＜a }，则 （∁R A ）∩B ＝ {2＜x ＜3或7≤x ＜10} ．若A ⊆C ，则a 的取值范围是 a ≥7 ．解：∵A ＝{x |3≤x ＜7}，B ＝{x |2＜x ＜10}，C ＝{x |x ＜a }， ∴∁R A ＝{x |x ＜3或x ≥7}，∴（∁R A ）∩B ＝{2＜x ＜3或7≤x ＜10}， ∵A ⊆C ，∴a 的范围是a ≥7，故答案为：{2＜x ＜3或7≤x ＜10}；a ≥714．若不等式2ax 2+ax ﹣2＜0对一切实数x

﹣300，当x ≥50时，w(x)=700x −(701x +10000x −9450)−300=−(x +10000x)+9150， ∴w(x)={−10x 2+600x −300，0＜x ＜50−(x +10000x )+9150，x ≥50； （2）若0＜x ＜50，w （x ）＝﹣10（x ﹣30）2+8700，当x ＝30时，w （x ）max ＝8700万元，若x ≥50，w(x)=−(x +10000x )+9150≤9150−2√x ⋅10000x =8950， 当且仅当x =10000x时，即x ＝100时，w （x ）max ＝8950万元， 因为8950＞8700，∴2020年年产量为100（千部）时，企业所获利润最大，最大利润是8950万元．21．（12分）已知幂函数f （x ）＝（m ﹣1）2•x 2m﹣1在（0，+∞）上单调递增． （1）求f （x ）的值域；（2）若∀x ＞0，f(x)x 2≥2−a 2x ，求a 的取值范围．解：（1）因为f （x ）＝（m ﹣1）2•x 2m ﹣1为幂函数，所以（m ﹣1）2＝1，即m ＝0或m ＝2，当m ＝0时，f （x ）＝x ﹣1在（0，+∞）上单调递减，不符合题意，当m ＝2时，f （x ）＝x 3在（0，+∞）上单调递增，符合题意，故函数的值域为R ；（2）若∀x ＞0，f(x)x 2≥2−a 2x ，则x ≥2−a 2x ， 即a ≥4x ﹣2x 2在x ＞0时恒成立，故a ≥（4x ﹣2x 2）max ，根据二次函数的性质可知，当x ＝1时，4x ﹣2x 2取得最大值2，故a ≥2，所以a 的取值范围为{a |a ≥2}．22．（12分）已知函数f(x)=ax−b 1+x 2是定义在[﹣1，1]上的奇函数，且f （1）＝﹣1． （1）求函数f （x ）的解析式；（2）判断f （x ）在[﹣1，1]上的单调性，并用单调性定义证明；（3）解不等式f （t ﹣1）+f （t 2）＞f （0）．解：（1）函数f(x)=ax−b 1+x 2是定义在[﹣1，1]上的奇函数， f （﹣x ）＝﹣f （x ）；−ax−b 1+x 2=−ax−b 1+x 2，解得b ＝0， ∴f(x)=ax 1+x 2，而f （1）＝﹣1，解得a ＝﹣2， ∴f(x)=−2x 1+x 2，x ∈[﹣1，1]． （2）函数f(x)=−2x 1+x 2在[﹣1，1]上为减函数； 证明如下：任意x 1，x 2∈[﹣1，1]且x 1＜x 2，则f(x 1)−f(x 2)=−2x 11+x 12−−2x 21+x 22=−2(x 1−x 2)(1−x 1x 2)(1+x 12)(1+x 22) 因为x 1＜x 2，所以x 1﹣x 2＜0，又因为x 1，x 2∈[﹣1，1]，所以1﹣x 1x 2＞0，所以f （x 1）﹣f （x 2）＞0，即f （x 1）＞f （x 2），所以函数f （x 1）＞f （x 2）在[﹣1，1]上为减函数．（3）由题意，f （t ﹣1）+f （t 2）＞f （0），又f （0）＝0，所以f （t ﹣1）+f （t 2）＞0， 即解不等式f （t 2）＞﹣f （t ﹣1），所以f （t 2）＞f （1﹣t ），所以{−1≤t 2≤1−1≤t −1≤1t 2＜1−t，解得0≤t ＜√5−12，所以该不等式的解集为[0，√5−12）．。

山东省淄博实验中学2023-2024学年高一上学期10月月考英语试卷
山东省淄博实验中学2023-2024学年高一上学期10月月考英语试卷学校:___________姓名：___________班级：___________考号：___________一、阅读理解The world is full of beauty in every corner. Here are four world’s top breathtaking and beautiful travelling destinations (目的地) for you to pay a visit to.DominicaDominica is known as “nature island” for a reason. This tiny Caribbean state, focuses on hot springs and long -distance walking in the rainforest rather than playing on the beach. Boiling Lake, in the Morne Trois Pitons National Park, can be reached by mountainous paths, a body of water that is well worth a visit.Lake Bled, SloveniaLake Bled is one of the largest freshwater lakes on Earth. At its center lies a small island, surrounded by deep blue water. It’s no surprise that Lake Bled has developed into one of the hottest destinations in Europe in recent years. Suitable for walking and diving (潜水) adventures, this is a corner of Slovenia that needs to be explored.Samburu, KenyaAs a hard-to-reach place in the heart of Kenya, Samburu provides a quiet and safe environment, which is good enough for some of Africa’s most unique wildlife to live in. The rich grassland of its national nature protection area is home to the endangered giraffe, as well as the pioneering Elephant Watch Camp.Positano, ItalyLocated on Italy’s Amalfi Coast, Positano is one of the most beautiful villages in Europe. Famous for its special small gift shops and waterside restaurants, not to mention the Byzantine Church (教堂), it makes for the perfect summer getaway. For divers, with its colorful plants and fish, it’s a really perfect place. Make sure to see its full form by taking a boat out from the beach for excellent sunset views.1．What can a tourist do in Dominica?A．Explore the nature protection area.B．Relax themselves at hot springs.C．Go shopping at the gift shops.D．Walk on the grassland freely. 2．Which is probably the best place if you’ re interested in African animals?A．Dominica.B．Lake Bled.C．Samburu.D．Positano. 3．What do Lake Bled and Positano have in common?A．They are both rich in fresh water.B．They are both great places to go diving.C．Tourists can enjoy the beautiful sunset.D．Tourists can visit the unique localchurch.As we grow up, it becomes natural for people around us to lose contact with the hobbies that once were dominant in their lives. While it’s painful to accept this, the new reality becomes normal for most of us as we face new academic, adult and job responsibilities.I’ve been dancing since I was four and I plan to continue dancing in college. However, I’ve always feared that dancing will affect my study and eventually become a brilliant memory of my childhood. After learning about Sommer Gentry’s story, I had an answer.Sommer Gentry, previously a professor of mathematics at the United States Naval Academy and a coach at the Naval Academy’s Swing Dance Club, is currently a teacher at NYU Grossman School of Medicine. Gentry and her husband also started a swing dance community to introduce non-dancers to swing dance.Through teaching, Gentry was inspired to view dancing from an engineering point of view. She said, “I realized it is an engineering question: how do you dance well with someone? It’d be great to give people mathematical and engineering proofs that they have to dance the way I say.” Gentry investigated the complex haptic (触觉的) communication behind the moves in swing dance and showed that two persons could move in coordination (协调) with pure haptic communication, She entered an exciting area of research which is about engineering, psychology and human motor control.It’s incredibly inspiring that Gentry was able to intertwine her academic work with her passion for dancing. Gentry said, “It means that even when I’m dancing outside, I’m thinking about my research project.”Gentry found that digging into her academic interest does not mean letting go of her other non-academic ones. Instead, she found a way to include both in her professional life. Just like me, Gentry is a mathematician and dancer, thus, her story resonates (引起共鸣) strongly with me, and I want to be like her in the future.4．What did the author think of dancing before learning of Gentry’s story?A．It was too challenging for her B．It’d gradually disappear from her life.C．It’d help develop her sense of responsibility.D．It brought her an unpleasantchildhood memory.5．What contributed to Gentry’s studying dancing from the angle of engineering?A．Her interest in exploring engineering proofs.B．Her husband’s need to promote his dance club.C．Her desire to be an expert in medicine and health.D．Her experience in teaching math and swing dance.6．What does the underlined word “intertwine” in Paragraph 5 probably mean?A．Hardly balance B．Carefully compare.C．Closely combine.D．Successfully challenge.7．What does the last paragraph imply about the author?A．She has decided to change her major.B．She will continue to pursue her hobby.C．She used to be Sommer Gentry’s student.D．She originally had little interest inengineering.Cows produce much methane (甲烷), the world’s second worst greenhouse gas, as they break down the grass. They are a large source of the greenhouse gases that are driving climate change. Now scientists have shown the pollution from cows can be reduced by adding a little seaweed (海藻) to their food.Recently, the researchers from the University of California studied 21 cows on a farm for about five months. They taught the cows to get their food from inside a special hood (罩), which allowed the scientists to know the amount of the methane the cows were giving off. They used a small amount of seaweed, which they mixed with the cows’ food.The results were surprisingly good. In some cases, the cows produced 82% less methane. The improvement depended on the kind of food the cows were given. Even the worst-polluting cows produced 33% less methane. Over the five months, the scientists didn’t see any signs that the cows’ stomachs were getting used to the seaweed and starting to produce more methane again. What’s more, the cows that were fed seaweed gained just as much weight as the other cows.But there are still some big problems with the idea of feeding cows seaweed. For one thing, there’s not enough seaweed to feed all of the cows in the world. So farmers would have to figure out a way to grow lots of seaweed. A bigger problem is that for most of their lives,cows live in the fields, where they eat grass. That means there’s no chance to feed them seaweed every day.Still, it’s very good news that something as simple as feeding cows seaweed can help reduce some of the pollution causing the climate crisis.8．Why did the researchers carry out the study?A．To improve the cows’ welfare.B．To test the effects of the seaweed.C．To measure the amount of methane produced by cows.D．To discover healthier grass to reduce the pollution from cows.9．What’s the third paragraph mainly about?A．The results of the study.B．The process of the research.C．The content of the experiment.D．The information of the subjects.10．What is the biggest challenge in the researchers’ opinion?A．Seaweed is pretty rare in the world.B．It’s hard to mix seaweed with grass.C．Cows fed with seaweed gained weight easily.D．Cows can hardly have daily access to seaweed.11．What is the author’s attitude towards the findings?A．Doubtful.B．Negative.C．Unclear.D．Positive.A broken heart. A sad ending to a love affair. That’s something most of us have experienced, or probably will. After all, it’s part of human life. But no question, the experience can be hard to get over.But research shows there are pathways through the heartache. Listening to sad music is a major one. It can help you begin to feel joy and hopefulness about your life again. It can arouse (激发，唤醒) the desire (渴望) to connect with others.Sad music can help heal and uplift you from your broken heart. A recent study from Germany found the emotional influence of listening to sad music is an arousal of feelings of empathy (共情), and a desire for positive connection with others. That, itself, ispsychologically healing. It draws you away from concentration on yourself, and possibly towards helping others in need of comfort.Another experiment, from the University of Kent, found that when people were experiencing sadness, listening to music that was “beautiful but sad” improved their mood. In fact, it did so when the person first consciously accept the situation causing their sadness, and then began listening to the sad music. That is, when they intended that the sad music might help, they found that it did.These findings link with other studies that show accepting your sad situation emotionally leads to healing and growth beyond it. It seems unbelievable but it does make sense. For example, research from Cornell University, published in Psychological Science, found that accepting discomfort about a life experience or new situation, and viewing it as a step towards growth and change, encourages people to find a pathway through it, beyond it. As Churchill famously said, “If you’re going through hell, keep going.” That discomfort points you towards creating a plan, a new action. It fuels hope.12．What can we learn from paragraph 3 and paragraph 4?A．Sad music can make people help others.B．Sad music can make sad people feel better.C．Sad music can make people believe in themselves.D．Sad music can make people concentrate on themselves.13．What does Churchill advise us to do when experiencing discomfort?A．Listen to a sad song.B．Avoid unwise actions.C．Find support from others.D．Face the discomfort directly. 14．How does the author develop this text?A．By listing figures.B．By giving directions.C．By comparing examples.D．By presenting research findings.15．Which is the best title for the text?A．How to Find Pathways through HeartachesB．How We React to A Broken Heart Matters a LotC．What We Can Do to Overcome Discomfort in LifeD．Why Listening to Sad Music Heals Your Broken Heart二、七选五During your school years, you will face many challenges. Sometimes you may not have all the solutions and need help. At this time, peer tutoring (同伴指导) is one of the most helpful tools. Peer tutors are understanding, helpful and especially honest. 16 Recognize your mistakesThis will probably be the most uncomfortable part, but peer tutors simply want you to be the best to your best ability. 17 They tell the truth about you, which may put you in an awkward position. But you have to learn to accept you’re not perfect and will make mistakes. You should feel fortunate that your peer tutor is recognizing your mistakes and giving you a chance to repair them.18Every tutor has a different learning and teaching style. If a tutor teaches you how to solve a math problem in a way that makes sense to you, but is also different from what you have learned in class, you will have to use that method because it works for you. If a tutor revises your paper and gives you advice, you will find your work in the future to change completely. Change is good. It is by no means something to be afraid of.Push you in timeSince we are human, it’s not unusual for us to be lazy sometimes. 19 However, if a tutor notices that you have been inactive, don’t be surprised if they call you out on it. Your tutor wants you to do the great things that you are capable of.Help you improveLast but not least, expect to improve. Peer tutoring can be difficult, but finally the goal is for you to improve as a student in various areas. Once you practice peer tutoring at school, you will notice a great change in your grades and your learning ability. 20 A．Give you a chance to changeB．Work out the best method for youC．Of course, it’s nothing to be ashamed of.D．So I think that’s really worth your efforts.E．Peer tutors are anxious to push you in study.F．They are always there to help you out through difficulties.G．The only way for them to ensure this is to be completely honest with you.三、完形填空early in my graduate career, my long hours and hard work were no longer successful in the lab, and I felt 22 about achieving my goals. Something had to change.As I began to 23 the reason for my 24 , I became increasingly aware that my “quiet time” at the lab bench was wasted. 25 thinking about science attentively (专心地), I was watching television or interacting with social media on my smartphone.

第Ⅰ卷（共45分）一、选择题（每个题3分，共45分）1．如图，郑州大河村遗址曾发现一批仰韶文化晚期的分间式房屋。
有些房屋是由较大的房屋修建隔墙后形成的若干套间，房屋周边还存在有客穴以及专供仓储的库房，这表明当时该地A．出现相对独立的家庭生活B．社会分工趋势已日益明显C．呈现出较明显的贫富分化D．私有制成为社会主流趋势2．“人”的概念起源甚早，文献记载，夏商时期就有“人”之称，甲骨卜辞里，“人”可指各种身份的人，“人”与“族”关系密切。
起初“人”的观念隐于“族”中，夏商西周时期，社会上几乎所有的人都生活于“族”之中。
战国时期，国家力量对于社会的控制增强，影响力加大，遂将某族之人称为“族人”。
出现这种现象是由于A．社会制度的完善B．礼乐制度对称呼的规范C．社会形态的变革D．人民思想观念发生变化3．东汉时，篇幅大、格式严格的大赋走向衰败；而篇幅短，句式多样、语言朴实的小赋逐渐兴起。
如张衡的《归田赋》：“弹五弦之妙指，咏周、孔之图书。
挥翰墨以奋藻，陈三皇之轨模。

=f(x)为奇函数；(3)求使f(x)=m，(x∈[0,1])有解的实数m的取值范围．答案和解析1.【答案】A【解析】解：∵集合A={−1,0，1}，集合B={0,1，2}，∴A∩B={0,1}．故选：A．利用交集定义直接求解．本题考查交集的求法，是基础题，解题时要认真审题，注意交集定义的合理运用．2.【答案】B【解析】解：由于1∈{0,1}，{1}⊆{0,1}，故选：B．根据集合与元素的关系，逐一判断四个答案，即可得到结论．本题考查的知识点是元素与集合关系的判断，其中正确理解集合元素与集合关系的实质，即元素满足集合中元素的性质，是解答本题的关键．3.【答案】C【解析】解；对于A选项，f(x)的定义域为R，g(x)的定义域为[0,+∞)，∴不是同一函数．对于B选项，f(x)的定义域为{x|x≠1}，g(x)的定义域为R，∴不是同一函数对于C选项，f(x)的定义域为R，g(x)的定义域为R，且两函数解析式化简后为同一解析式，∴是同一函数对于D选项，f(x)的定义域为[1,+∞)，g(x)的定义域为(−∞,−1]∪[1,+∞)，∴不是同一函数故选：C．若两个函数是同一个函数，则函数的定义域以及函数的对以关系都得相同，所以只要逐一判断每个选项中定义域和对应关系是否都相同即可．本题主要考查了函数三要素的判断，只有三要素都相同，两函数才为同一函数．【解析】解：y=√x的定义域为[0,+∞)；y=lg|x|的定义域为{x|x≠0}；y=x3+3的定义域为R；y=1的定义域为{x|x≠0}．x故选：C．逐一求出四个函数的定义域得答案．本题考查函数的定义域及其求法，是基础题．5.【答案】B【解析】解：当x=0时，f(0)=20+0=1>0，<0，当x=−1时，f(−1)=2−1−1=−12由于f(0)⋅f(−1)<0，且f(x)的图象在[−1,0]上连续，根据零点存在性定理，f(x)在(−1,0)上必有零点，故选：B．将选项中区间的两端点值分别代入f(x)中验证，若函数的两个值异号，由零点存在定理即可判断零点必在此区间．本题主要考查了函数的零点及零点存在性定理，关键是将区间的端点值逐个代入函数的解析式中，看函数的两个值是否异号，若异号，则函数在此开区间内至少有一个零点．6.【答案】A【解析】【分析】本题考查的知识点是指数函数的图象与性质，其中根据函数y=7+a x−1(a>0,a≠1)的解析式，结合函数图象平移变换法则，求出平移量是解答本题的关键．根据指数函数的性质，我们易得指数函数y=a x(a>0,a≠1)的图象恒过(0,1)点，再根据函数图象的平移变换法则，求出平移量，进而可以得到函数图象平移后恒过的点P 的坐标．解：由指数函数y=a x(a>0,a≠1)的图象恒过(0,1)点，而要得到函数y=7+a x−1(a>0,a≠1)的图象，可将指数函数y=a x(a>0,a≠1)的图象向右平移1个单位，再向上平移7个单位．则(0,1)点平移后得到(1,8)点．点P的坐标是(1,8)．故选A．7.【答案】C【解析】解：根据指数函数和对数函数的性质，知log√20.2<0，0<0．2√2<1，√20.2>1，即0<a<1，b<0，c>1，∴b<a<c．故选：C．根据指数函数，对数函数和幂函数的性质分别判断a，b，c的大小，即可判断．本题主要考查函数数值的大小比较，利用指数函数，对数函数和幂函数的性质是解决本题的关键．8.【答案】D【解析】【分析】利用奇函数的性质即可得出．本题考查了奇函数的性质，考查了推理能力与计算能力，属于中档题．【解答】解：当x<0时，−x>0，∵当x>0时f(x)=x(1−x)，∴当x<0时，f(−x)=−x(1+x)，∵f(x)是R上的奇函数，∴f(x)=−f(−x)=x(1+x)，故选：D．【解析】解：∵f(x)是偶函数，∴f(−32)=f(32)，f(−1)=f(1)，f(−2)=f(2)，又f(x)在(−∞,−1]上是增函数，∴f(−2)<f(−32)<f(−1)即f(2)<f(−32)<f(−1)故选：D．题目中条件：“f(x)为偶函数，”说明：“f(−x)=f(x)”，将不在(−∞,−1]上的数值转化成区间(−∞,−1]上，再结合f(x)在(−∞,−1]上是增函数，即可进行判断．本小题主要考查函数单调性的应用、函数奇偶性的应用、奇偶性与单调性的综合等基础知识，考查运算求解能力、化归与转化思想．属于基础题．10.【答案】A【解析】解：当x<0时f(x)>1且为减函数可排除B，C当x>0时由指数函数的图象可排除D故选：A．可用排除法选择，根据指数函数的图象和性质，当x<0时f(x)>1且为减函数，当x>0时由指数函数的图象可排除D．本题主要考查指数函数的图象和性质的应用，同时，还考查了客观题处理要灵活，可选择特殊法，排除法，验证法等，提高解题效率．11.【答案】B【解析】解：∵函数f(x)是奇函数，在(0,+∞)上单调递减，且f(12)=0，∴f(−12)=0，且在区间(−∞,0)上单调递减，∵当x<0，当−12<x<0时，f(x)<0，此时xf(x)>0当x >0，当0<x <12时，f(x)>0，此时xf(x)>0 综上xf(x)>0的解集为{x|0<x <12或−12<x <0} 故选：B ．由已知中f(12)=0，且在(0,+∞)上单调递减，可得f(−12)=0，且在区间(−∞,0)上单调递减，分类讨论后，可得xf(x)>0的解集本题主要考查函数的单调性和奇偶性的综合应用，体现了转化的数学思想，判断出f(−12)=0，且在区间(−∞,0)上单调递减是解题的关键．12.【答案】B【解析】解：因为f(x)=e x ，所以f(x 1+x 2)=e x 1+x 2，f(x 1)f(x 2)=e x 1⋅e x 2=e x 1+x 2， 所以f(x 1+x 2)=f(x 1)f(x 2)，故①正确，f(x 1x 2)=e x 1x 2，f(x 1)+f(x 2)+f(x 2)=e x 1+e x 2，则f(x 1x 2)≠f(x 1)+f(x 2)，故②错误，因为函数f(x)=e x 在R 上为单调递增函数，所以f(x 1)−f(x 2)x 1−x 2>0，故③正确，故选：B ．根据指数函数的解析式逐个求出f(x 1+x 2)，f(x 1)f(x 2f(x 2),f(x 1x 2),f(x 1)++f(x 2)的解析式即可判断①②，再根据函数的单调性即可判断③．本题考查了命题的真假判断，涉及到指数函数的单调性等应用，考查了学生的运算转化能力，属于基础题．13.【答案】[−4,3]【解析】解：由函数的图象可得，当x =5时，函数取得最小值为−4，函数的最大值为3，故函数的值域为[−4,3]， 故答案为[−4,3]．利用函数的图象求函数的最大值和最小值，从而求得函数的值域．本题主要考查函数的图象的特征，利用函数的图象求函数的最大值和最小值，属于基础题．14.【答案】3【解析】解：由分段函数可知，f(−1)=0，∴f(f(−1))=f(0)=2．∴f{f[f(−1)]}=f(2)=2+1=3．故答案为：3．根据分段函数，直接代入进行求值即可．本题主要考查分段函数的应用，注意分段函数的取值范围，比较基础．15.【答案】(1,2)【解析】解：函数y=log(2−a)x在定义域内是减函数，∴0<2−a<1，即1<a<2，所以a的取值范围是(1,2)故答案为(1,2)．根据对数函数的图象和性质即可得到答案．本题考查了对数函数的图象和性质，属于基础题．16.【答案】2【解析】解：∵函数f(x)=a x(a>0,a≠1)在[0,1]上的最大值与最小值的和为3，∴a0+a1=3，∴a=2．故答案为：2．利用函数f(x)=a x(a>0,a≠1)在[0,1]上的单调性与f(x)在[0,1]上的最大值与最小值的和为3即可列出关于a的关系式，解之即可．本题考查指数函数单调性的应用，得到a的关系式，是关键，考查分析与计算能力，属于基础题．第11页，共13页17.【答案】解：(1)∵集合A ={x|1≤x ≤4}，B ={x|−1<x <3}，∴A ∪B ={x|−1<x ≤4}．(2)∵C ={x|a −1≤x ≤a}，B ={x|−1<x <3}，B ∩C =C ，∴C ⊆B ，∴{a −1>−1a <3，解得0<a <3， ∴a 的取值范围(0,3)．【解析】(1)由集合A ={x|1≤x ≤4}，B ={x|−1<x <3}，能求出A ∪B ．(2)由C ={x|a −1≤x ≤a}，B ={x|−1<x <3}，B ∩C =C ，得C ⊆B ，由此能求出a 的取值范围．本题考查并集的求法，考查实数的取值范围的求法，是基础题，解题时要认真审题，注意并集、子集定义的合理运用．18.【答案】解：(1)(−0.1)0+√23×223+(14)−12=1+213×223+(2−2)−12=1+2+2=5．(2)log 3√27+lg25+lg4=12log 327+lg100 =32+2

A few years ago, I was given a wallet. It was small, with only a single pocket for cash, cards and coins. A zipper kept everything inside from falling out and a beautiful elephant was woven into its front panel. The wallet came to me all the way from Tanzania, gifted to me by a close friend. I fell in love with it immediately, it was the perfect size and came from a place I hoped to someday visit. I carried it everywhere；it was always precariously （不安全地）hanging out of one pocket or another.But the wallet was not only beautiful; it had a personality：it loved to run away? as I told my parents over and over again, only to receive eye rolls in return. "Fra nces, really? you've lost it again?” they would say every time I misplaced it.I seem to have a habit of losing things—jackets, water bottles, text books, even shoes. And every time I would report another loss, my parents would have a harder time believing it. "I swear,“ I would assure them, “it just ran away from me. " Unfortunately they never believed that, and so often I was left to search and pray for the items to come back to me.One day? I was on my way home from school with a couple of friends. We had taken subway using our transportation cards. Mine was inside my wallet. Once on the other side of the turnstile（旋转栅门），I put the elephant pouch back in my pocket and set off for the rock climbing gym, where we would spend a couple of hours before going home. When I got to the gym, I reached for my wallet only to find it wasn't there. This time I panicked.注意：1.续写词数应为150左右；2.请按如下格式在答题卡的相应位置作答。

Who will be interested in the activity?A. students and parentsB. kite expertsC. office workersD. kite companiesBIn 1938 Portugal held a national competition to identify the country‘s most ―Portuguese‖ Village. Sticking to a rocking promontory(海角) far above the Beira Baixa plains, Monsanto is easyily the most impressive. So it came out on top.Cottage, a lot of which are made of very large round rocks, seem to grow out of the mountain itself. Above them rises a stone fortress（城堡）, parts of which predate even the arrival of the moors. And views across the plains are, simply put, astonishing.Since being honored as the most Portuguese village, Monsanto has reminded largely separated from modernization. These days, goats and chickens seem to outnumber humans in the village. Most young people leave for large cities and the growing investment in the area‘sheritage(遗产) has not encouraged more attractions for the younger generation. Tourists walking along the village‘s tiny streets can see elde rly women walking and chatting in doorways.Several houses near the village entrance are surprisingly grand. Halfway to the castle you‘ll come across the gruta, a cozy cave apparently once used as a pub—and still used as such. This stone fortress seems alm ost to have grown out of the hillside that supports. It‘s a wonderfully beautiful site, populated wildflowers.After Dom Sancho I drove out the Moors in the 12th century, the fortress was strengthened. Dom Dinis improved it, but after centuries of attacks from across the border it finally felt into ruin. Just below the entrance is a public square. To the right is a ruined Renaissance church and bell tower.On 3 May Monsanto comes alive in the Festa das Cruzes, remembering a siege(围困) in the Middle Ages. The story goes that the starving villagers threw their last lonely cow over the walls, making their enemies believe they had plenty of food, so they immediately abandoned the siege. These days, young girls throw baskets of flowers instead, after which there‘s dancing and singing beside the castle wall.24. what is Monsanto like today?A. It has a lot of farms.B. Its youth love farming.C. Its population is falling.D. It has become modern.25. Why did the enemies end the siege?A. They felt hungry.B. They were tricked.C. They were attacked.D. They feared the cow.26. What do we know about the fortress?A. It has long been used as a pub.B. It was first constructed by Dom Dinis.C. There is celebration every May beside it.D. You have to go through it to enter the village.27. What is the author‘s purpose in writing the text?A. To discuss rural life in Portugal.B. To report a national competition.C. To explain the history of the Portugal.D. To introduce a unique ancient village.CAs any plane passenger will confirm, a crying baby is almost impossible to ignore, no matter how hard you try. Now scientists believe they may have worked out why. A baby‘s cry pulls at the heartstrings(扣人心弦) in a way while other cries don‘t, researchers found.Researchers found that a baby‘s cry can trigger unique emotional responses in the brain, making it impossible for us to ignore them—whether we are parents or not. Other types of cries, including calls of animals in great pain, fail to get the same response—suggesting the brain is programmed to respond specifically to a baby‘ cry.A team of Oxford University scientists scanned the brains of 28 men and women as they listened to a variety of calls and cries. After 100 milliseconds-roughly the time to blink(眨眼)—two parts of the brain that respond to emotion lit up. Their response to a baby‘s cry was particularly strong. The response was seen in both men and women—even if they had no children.Researcher Dr Christine Parsons said, “You might read that men should just notice a baby and step over it and not see it, but it‘s not true. There is a special processing in men and women, which makes sense from an evolutionary(演变的) view that both men and women would be responding to these cries.”The study was in people who were not parents, yet they are all responding at 100ms to these particular cries, so this might be a fundamental response present in all of us regardless of parental status.Fellow researcher Katie Young said it may take a bit longer for someone to recognize their own child‘s cries because they need to do more “fine-grained analysis”. The team had previously found that our reactions speed up when we hear a baby crying. Adults performed better on computer games when they heard the sound of a baby crying than after they heard recordings of adults crying.28. A baby‘s cry is difficult to ignore because it _____.A. keeps on cryingB. cries harder than adultsC. causes people great painD. makes people feel strong emotions29.The underlined word“trigger”in Paragraph 2 probably means“_____”.A. removeB. avoidC. causeD. cure30. What may Christine Parsons agree to?A. Almost everyone makes certain response to a baby’s cries.B. A crying baby makes no sense to people without children.C. Men pay less attention to a crying baby than women.D. Parents can hardly recognize their own babies‘ cry.31. What‘s the main idea of the text?A. Why you can‘t get a baby‘s cry out of your headB. How to recognize different babies‘ cries.C. Why a baby is easy and likely to cry.D. How to prevent a baby crying.DThe note taped to the host stand at The Prime Rib says it all.―We fought the battle the longest, but we give in!‖ it reads. ―It‘s now a completely informal world; they wear whatever they wish. They want a warm, easy, friendly atmosphere, even in ―fine dining‖. So we decide to go with the flow.Yes, after almost half a century, The Prime Rib has switched to business casual.It is among most of today‘s finest dining establishments—including Charleston, the Black Olive, and the Capital Grille—that have decide to lighten up. They have given up caring too much about what their guests are dressed in as before, adopting a come-as-you-are attitude. At these restaurants, you‘re likely to see casual clothes such as khakis (trousers made of khaki cloth) and Hawaiian shirts.―We‘re a business first,‖ says David De rewicz, general manager of the impressive dining establishment. ―And we were losing business with our jacket requirements‖. He kept a list of over 20 people who told him, ―If you drop the jacket policy, we‘ll come back.‖Once the dress code shift was seriously being considered, Derewicz made dozens of phone calls to long-time guests. Most said they don‘t mind the change as long as the restaurant itself—with its white table clothes, dark leather chairs, grand piano, and tuxedoed waitstaff—stayed the same.―Since the change was introduced last summer, we‘ve not lost a guest,‖ says Derewicz.On a secret night at the Prime Rib, the scene was pretty much the same as it‘s ever been—lots of men in jackets and ties, some in shirts and slacks, but now occasional khakis and polo shirts thrown in.It turns out that people are pretty capable of policing themselves, even without a formal dress code.While some traditionalists may argue that the Prime Rib‘s reputation has been damaged a bit, Derewicz feels that the restaurant has moved ahead and finally strengthened their band.32. The Prime Rib‘s note mainly tells people _________.A. its long historyB. a better reputationC. its change in dress code C. its battle with other restaurant33. The underlined words ―lighten up‖ in Paragraph 4 probably means ________.A. follow a long traditionB. take a matter less seriouslyC. make something continue as beforeD. help each other to achieve something34. According to Derewicz, following the formal code means ________.A. further developmentB. a better reputationC. low efficiencyD. failing profits35. What do we know about the Prime Rib now?A. It is praised by some traditionalists.B. The police come to protect its guess.C. Most of its guests still wear formal clothes.D. Most people go there in khakis and polo shirts.第二节(共5小题; 每小题2分，满分10分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
