河南省郑州外国语学校2024-2025学年高一上学期第一次月考英语试卷一、阅读理解Amsterdam is one of the most popular travel destinations in the world, famous for its beautiful canals, top art museums, cycling culture and so on. It is the capital city of the Netherlands and often referred to as the “Venice of the North” because of its expansive system of bridges and canals. Here are some of the key points to remember as you plan your trip to Amsterdam.Must-See AttractionsMost visitors begin their Amsterdam adventure in the Old Centre, which is full of traditional architecture, shopping centers, and coffee shops. You’ll also want to check out Amsterdam’s Museum Quarter in the South District, which is great for shopping at the Albert Cuyp Market and having a picnic in the V ondelpark. The top museums to visit there are the Rijksmusuem, the Ann Frank House, and the Van Gogh Museum.If You Have TimeThere are several other unique districts in Amsterdam, and you should try to explore as many of them as time allows. The Canal Ring is a UNESCO World Heritage Site that was originally built to attract wealthy home owners and is a center for celebrity spotting and nightlife today. The Plantage area has most of the city’s museums and the botanical gardens.Money Saving Tips●Unless you really want to see the tulips(郁金香) blooming, avoid booking between mid-March and mid-May. This is when hotel and flight prices rise.●Look for accommodations in Amsterdam’s South District, where rates are generally cheaper than in the city center.●Buy train tickets at the machine instead of the counter to save a bit of money.●Instead of hiring a tour guide, hop on a canal boat. They’re inexpensive and will give youa unique point of view of the city.Check out our homepage to view price comparisons for flights, hotels, and rental cars beforeyou book.1.What can be learned about Amsterdam from this passage?A.The Van Gogh Museum lies in the South District.B.The Canal Ring is a place to attract garden lovers.C.The Old Centre is a UNESCO World Heritage Site.D.Amsterdam is called the “Venice of the North” because of its location.2.In order to save money in Amsterdam, you can ________.A.arrange a guided tour B.buy train tickets at the counterC.reserve a hotel in the South District D.book flights between mid-March andmid-May3.Where is the passage most probably taken from?A.A magazine.B.An essay.C.A report.D.A website.While famous foreign architects are invited to lead the designs of landmark buildings in China such as the new CCTV tower and the National Center for the Performing Arts, many excellent Chinese architects are making great efforts to take the center stage.Their efforts have been proven fruitful. Wang Shu, a 49-year-old Chinese architect, won the 2012 Pritzker Architecture Prize — which is often referred to as the Nobel Prize in architecture — on February 28. He is the first Chinese citizen to win this award.As head of the Architecture Department at the China Academy of Art (CAA), Wang has an office at the Xiangshan campus of the university in Hangzhou. Many buildings on the campus are his original creations. The style of the campus is quite different from that of most Chinese universities. Many visitors are amazed by the complex architectural space and different building types. The curves (曲线) of the buildings perfectly match the rise and fall of hills, forming a unique view.Wang collected more than 7 million abandoned bricks of different ages. He asked the workers to use traditional ways to make the bricks into walls, roofs and corridors. This creation attracted a lot of attention thanks to its mixture of modern and traditional Chinese elements (元素).Wang’s works show a deep understanding of modern architecture and a good knowledge oftraditions. Through such a balance, he had created a new type of Chinese architecture.Wang believes traditions should not be sealed in glass boxes at museums. “That is only evidence that traditions once existed. Many Chinese people have a misunderstanding of traditions. They think tradition means old things from the past. In fact, tradition also refers to the things that have been developing and that are still being created,” he said.The study of traditions should be combined with, practice. Otherwise, the recreation of traditions would be artificial and empty, he said.4.Wang’s winning of the prize means that Chinese architects are ________.A.following the latest world trend B.getting international recognitionC.working harder than ever before D.relying on foreign architects5.What impressed visitors to the CAA Xiangshan campus most?A.Its hilly environment.B.Its large size.C.Its unique style.D.Its diverse functions.6.What made Wang’s architectural design a success?A.The mixture of different shapes.B.The balance of East and West.C.The use of popular techniques.D.The harmony of old and new.7.What should we do about Chinese traditions according to Wang?A.Spread them to the world.B.Protect them at museums.C.Teach them in universities.D.Recreate them in practice.Bed rotting — the practice of spending long periods of time just staying under the covers with snacks, screens and other creature comforts — is gaining popularity on social media. Some Generation Z trend followers are now considering it as a form of self-care, but doctors warn too much could be “sign of depression”. Are these extended breaks really wise for one’s mental health — or could they be a cause for concern?Dr. Ryan Sultan, a professor treating many young people, called the bed rotting trend attractive. “In our culture today, with too much to do, too many expectations and too much productivity, many young individuals (个人) are feeling tired and often aren’t getting enough sleep. It’s easy to see why taking time off to lie around is attractive,” Sultan said. “In many ways, this is beneficial. It’s a chance to get away from real-life problems and clear your head beforereturning to life in a better state of mind,” he added.For the downside, however, he said a long-term need or desire for bed rotting could do harm to one’s physical health. Spending too many daytime hours in bed — awake or not — could destroy sleep schedules. Our brains are fine-tuned for sleep in darkness and alertness in light. Lying in bed half-asleep during the day will worsen sleep schedules — once that happens, it is a challenge to fix. It could also lead to blood pressure problems and obesity (肥胖).Long-term need or desire for bed rotting could also be a warning sign of depression, according to a mental health expert. Dr. Marc Siegel, professor of medicine, agreed that while some downtime can be useful in terms of de-stressing and rejuvenation (更新), too much bed rotting is bad. In addition to increasing the risk of depression, it contributes to decreased motivation (动力) as well.Instead of bed rotting, Siegel recommends regular exercise as a better form of de-stressing. While the occasional lazy day can be beneficial, too much could have the opposite effect. If it happens every day, that’s a fairly sensitive test for depression. Those who lack the motivation to get out of bed could also try calling or texting a family member for support, socializing with close friends, finding a small task to complete, or reaching out to a medical professional for help. 8.According to Dr. Ryan Sultan, why do young people like bed rotting?A.Bed rotting is a way to escape stress.B.Bed rotting helps fix sleep schedules.C.They are unwilling to socialize with friends.D.They are fond of what is popular on social media.9.What does the word “fine-tuned” underlined in Paragraph 3 probably mean?A.Quickly-started.B.Well-trained.C.Badly-needed.D.Ill-equipped. 10.What can we learn from the passage?A.Feeling down leads to decreased motivation.B.Sleeping in light can increase the risk of depression.C.Young individuals meet expectations through bed rotting.D.Being lazy from time to time can be good for individuals.11.What is the passage mainly talking about?A.Different opinions on how to become motivated.B.Main causes of the long-term need for bed rotting.C.Practical suggestions for young people to deal with stress.D.Possible problems from lying in bed for extended periods of time.Sportsmanship is the cornerstone of competitive sports, representing the principles of fair play, respect and honesty. It goes beyond winning and losing, emphasizing the importance of moral behavior, respecting each other, and fellowship.At the heart of sportsmanship lies the concept of fair play. It fosters (培养) a culture of rule-following, fair judgment, and equal opportunities for all participants. Fair play encourages athletes to compete with integrity, showing honesty and accepting the outcomes gracefully. It fosters an environment where cheating, unsportsmanlike and rude behavior are discouraged. By upholding fair play, athletes develop a sense of morality (道德) and a strong character that extends beyond the field of sports.Sportsmanship also includes respect and empathy (共情), creating an environment that encourages understanding and camaraderie. Athletes show respect for opponents, officials, and teammates, recognizing their contributions and valuing their abilities. They appreciate the various backgrounds, skills and perspectives that athletes from different teams bring to the game. Through respect and empathy, sportsmanship bridges gaps, promotes inclusivity and fosters a sense of unity among athletes and fans alike.Sportsmanship is shown by athletes who act as role models, inspiring others with their conduct on and off the field. When athletes display sportsmanship, they send a powerful message to young fans, teaching them the importance of fair play, respect and moral behavior. This positive influence extends to society as a whole, where sportsmanship can shape attitudes, values and behaviors beyond the field of sports. By upholding the principles of sportsmanship, athletes contribute to a healthier, more caring society.Sports organizations, coaches and educators play an important role in promoting sportsmanship. They should foster an environment that encourages fair play, respect and honesty. Emphasizing sportsmanship in training programs and competitions helps athletes develop a strong moral compass,empowering them to make moral choices both in sports and in life. Furthermore, fans and audience should also welcome sportsmanship, creating a positive atmosphere thatencourages fair competition and respect for all participants.Sportsmanship is the bedrock of competitive sports, emphasizing the values of fair play and respect. It improves the sporting experience, fosters unity and shapes athletes into responsible and caring individuals. By promoting sportsmanship, we can create a sporting culture where victories are celebrated but fairness, respect and the spirit of the game take center stage.12.What does the underlined word “camaraderie” mean in Paragraph 3?A.Friendship.B.Leadership.C.Contribution.D.Competition. 13.What are Paragraphs 2 and 3 mainly about?A.How sportsmanship is understood.B.Why sportsmanship is stressed.C.When sportsmanship is shaped.D.Where sportsmanship is treasured. 14.What can be learned from Paragraph 5?A.Athletes should be trained to make moral choices.B.Audience could influence athletes’ performance in sports.C.Promoting sportsmanship requires everyone’s contribution.D.Officials should take a lead in creating a positive atmosphere.15.What is the best title for this passage?A.Sportsmanship:Advantages of Doing SportsB.Sportsmanship:Spirit of Fair Play and RespectC.Showing Sportsmanship:Qualities of a Good PlayerD.Teaching Sportsmanship:Values of Honesty and CourageIn our modern economy, accelerated learning can be crucial for success. Learning faster means gaining more knowledge—quicker than others. 16 Anyone can learn from them and accelerate their learning process with the following techniques. Combine Learning Styles That Play to Your StrengthsWhen you aim to accelerate your learning, what you choose to learn should not be limited to a curriculum or classroom structure. 17 Different materials along with your learning style can accelerate or slow down your comprehension process. The best learning style is the one that makes it easier to process, or comprehend ideas, and subjects faster. Once you know your learning strengths and weaknesses, you can choose learning strategies that play to your strengths. SeekFirst to Understand The Basic Structure of The Topic You Choose18 So you need to seek first to understand the basics. In other words, you have to get to know the tree’s root, trunk, then branch out from there. Don’t start from the branches or the leaves, pursue the root and work your way to the topic. Therefore, whatever topic you choose to learn or study, just start with the basics. Give Yourself Plenty of Time in Both “Focused” And “Diffused”(分散的)ModesNormally, the human brain is not meant to stay in “focused” mode for hours at a time.19 Consequently, when your brain is active for a very long time, you’re actually blocking your access to the diffused mode — a more relaxed state.Therefore, diffused mode is just as valuable as the focused mode. So — just take breaks, let your mind wander, think about other things, and give your brain plenty of time to make better connections. 20A.You can benefit a lot from staying focused.B.Smart learners don’t have any special secrets.C.You should try to choose whatever you like best.D.Every topic or subject has a logical structure to it.E.Then you can learn better by imposing breaks on yourself.F.Long-lasting attention to a single task can block memory and recall.G.You can practically choose content from many sources, experts, and authors.二、完形填空For me, nothing is more satisfying than discovering hidden treasure in secondhand shops.21 , one person’s trash is another person’s 22 .Two years ago, I 23 a collection of old, dusty photos. I thought: if these were mine, or my family’s, I’d want someone to 24 them to me. So I made it my goal to do so for others.I’ve since visited secondhand shops weekly, and have 25 more than 50,000 of these items.

The firstitem I 27 was a tape of a family holiday that I digitized. It was a video of two parents and a son of 28 age on a trip in the 90s — the son was wearing a T-shirt with the words “Wesleyan swimming” on it. My followers asked university swimming coaches across the US if they knew the student. After just a few days, someone recognized him and we found him on social media. He couldn’t believe it and was extremely excited to get the tape.The 29 we’ve taken to find someone is four months, but I’m proud that we still 30 to do it.

②f (x )有最大值; ③f (x )不是二次函数.解:因为f (x ﹣1)为偶函数,则f (﹣x ﹣1)=f (x ﹣1), 所以f (x )的图象关于直线x =﹣1对称, 又f (x )有最大值,所以可取f (x )=﹣|x +1|. 故答案为:﹣|x +1|(答案不唯一).14.已知关于x 的不等式(a 2﹣4)x 2+(a +2)x ﹣1≥0的解集是空集,求实数a 的取值范围 [﹣2,65) .解:设f (x )=(a 2﹣4)x 2+(a +2)x ﹣1,当a 2﹣4=0,即a =﹣2(a =2不是空集)时,不等式解集为空集; 当a 2﹣4≠0时,根据题意得:a 2﹣4<0,Δ<0, ∴(a +2)2+4(a 2﹣4)<0,即(a +2)(5a ﹣6)<0, 解得:﹣2<a <65, 综上a 的范围为[﹣2,65).故答案为:[﹣2,65).15.已知函数f (x )=log 2x 的反函数为g (x ),且有g (a )g (b )=16,若a ≥0,b ≥0,则42a+b+1a+2b的最小值为34.解:函数f (x )=log 2x 的反函数为g (x )=2x ,∵g (a )g (b )=16,∴2a ×2b =16,即2a +b =16,则a +b =4, 又a ≥0,b ≥0,则a +4>0,b +4>0, ∴42a+b +1a+2b=4a+4+1b+4=112[(a +4)+(b +4)](4a+4+1b+4)=112(5+4(b+4)a+4+(a+4)b+4)≥112(5+2√4(b+4)a+4⋅(a+4)b+4)=34, 当且仅当a =4,b =0时取等号, 故42a+b+1a+2b 的最小值为34.故答案为:34.16.已知函数f (x )=lg (x 2﹣4x )+2023x ﹣2+20232﹣x ,则不等式f (3x )<f (x +3)成立的x 的取值范围是(14,32) .解:已知函数f (x )=lg (x 2﹣4x )+2023x ﹣2+20232﹣x ,则f (x )=lg [(x ﹣2)2﹣4]+2023x ﹣2+20232﹣x ,设g (x )=f (x ﹣2),则g (x )=lg (x 2﹣4)+2023x +2023﹣x ,其定义域为R ,有g (x )=g (﹣x ), g (x )为偶函数,由y =g (x )的解析式易得y =g (x )在(2,+∞)为增函数, 又f (3x )<f (x +3),即g (3x ﹣2)<g (x +3﹣2), 则有|3x ﹣2|<|x +1|,变形可得:8x 2﹣14x +3<0, 解可得:14<x <32,即x 的取值范围是(14,32).故答案为:(14,32).四、解答题(本大题有6小题,共70分,其中第17题10分,第18-22题每题12分.解答应写出文字说明,证明过程或演算步骤)17.(10分)(1)计算:3log 32−2log 23⋅log 278+13log 68+2log 6√3. (2)解不等式:log 2(2﹣x )<log 4x .解:(1)原式=2−2log 23×log 32+13log 623+2log 6312=2﹣2+log 62+log 63=1; (2)log 2(2−x)<log 4x ⇒log 2(2−x)<12log 2x =log 2√x ,因为y =log 2x 在(0,+∞)上单调递增,所以{2−x >0x >02−x <√x,解得1<x <2,故不等式的解集为(1,2). 18.(12分)设函数f (x )=ax 2+(1﹣a )x ﹣1.(1)命题p :∃x ∈R ,使得f (x )<x ﹣3成立.若P 为假命题,求实数a 的取值范围;(2)求不等式f (x )<0(a <0)的解集.解:(1)∵P 为假命题,∴非p :∀x ∈R ,f (x )≥x ﹣3恒成立为真命题,即不等式ax 2﹣ax +2≥0 在R 上恒成立,当a =0时,2≥0恒成立,则a =0满足题意,当a >0时,a 2﹣8a ≤0,则0<a ≤8,综上,{a |0≤a ≤8};(2)当a <0时,不等式f (x )<0等价于(ax +1)(x ﹣1)<0,当a =﹣1时,则 −1a =1 原不等式即为﹣(x ﹣1)2<0,解得x ≠1;当﹣1<a <0时,则 −1a >1,解得x <1或 x >−1a ,当a <﹣1时,则 −1a <1,解得 x <−1a 或x >1;综上所述,当a <﹣1时,原不等式的解集为 {x|x <−1a 或x >1};当a =﹣1时,原不等式的解集为{x |x ≠1};当﹣1<a <0时,原不等式的解集为{x |x <1或 x >−1a }.19.(12分)已知函数f(x)=(12)x 2−mx ,g(x)=x 2−2ax ,x ∈R .(1)若f (x )在[1,2]上单调递增,求m 的取值范围.(2)若m =2,对任意的x 1∈R ,总存在x 2∈[1,2],使得f (x 1)≤g (x 2)成立,求a 的取值范围. 解:(1)由f(x)=(12)x2−mx ,设t =x 2﹣mx ,则y =(12)t , 所以函数y =(12)t 在R 上单调递减,函数t =x 2﹣mx 开口向上,对称轴方程为x =m 2,所以函数t =x 2﹣mx 在(−∞,m 2)单调递减,在(m 2,+∞)上单调递增.因为f (x )在[1,2]上单调递增,所以m 2≥2,所以m ≥4,所以m 的取值范围为[4,+∞).(2)因为m =2,对任意的x 1∈R ,总存在x 2∈[1,2],使得 f (x 1)≤g (x 2)成立,所以只需f (x 1)max ≤g (x 2)max ,由(1)可知,f (x )在(−∞,m 2)单调递增,在(m 2,+∞)上单调递减.当m =2时,f(x 1)max =f(m 2),代入f (x )解析式,可得f (x 1)max =2,而g (x )=x 2﹣2ax ,开口向上,对称轴x =a ,所以g (x )在(﹣∞,a )上单调递减,在(a ,+∞)上单调递增,当a ≥2时,g (x )在[1,2]上单调递减,g (x )max =g (1)=1﹣2a ,所以2≤1﹣2a ,解得a ≤−12,舍去;当a ≤1时,g (x )在[1,2]上单调递增,g (x )max =g (2)=4﹣4a ,所以4﹣4a ≥2,解得a ≤12,又a ≤1,所以a ≤12;当1<a <2时,若|1﹣a |>|2﹣a |,即32<a <2时,g (x )max =g (1)=1﹣2a , 所以2≤1﹣2a ,解得a ≤−12,与假设不符合,舍去;若|1﹣a |=|2﹣a |,即a =32时,g (x )max =g (1)=g (2)=1﹣2a ,所以2≤1﹣2a ,解得a =−12,不符合a =32,舍去;若|1﹣a |<|2﹣a |,即1<a <32时,g (x )max =g (2)=4﹣4a ,所以2≤4﹣4a ,解得a ≤12与假设不符,舍去,综上,a 的取值范围为(−∞,12].20.(12分)杭州亚运会田径比赛10月5日迎来收官,在最后两个竞技项目男女马拉松比赛中,中国选手何杰以2小时13分02秒夺得男子组冠军,这是中国队亚运史上首枚男子马拉松金牌.人类长跑运动一般分为两个阶段,第一阶段为前1小时的稳定阶段,第二阶段为疲劳阶段.现一60kg 的复健马拉松运动员进行4小时长跑训练,假设其稳定阶段作速度为v 1=30km /h 的匀速运动,该阶段每千克体重消耗体力ΔQ 1=t 1×2v 1(t 1表示该阶段所用时间),疲劳阶段由于体力消耗过大变为v 2=30﹣10t 2的减速运动(t 2表示该阶段所用时间).疲劳阶段速度降低,体力得到一定恢复,该阶段每千克体重消耗体力ΔQ 2=t 2×2v 2t 2+1,已知该运动员初始体力为Q 0=10000kJ ,不考虑其他因素,所用时间为t (单位:h ),请回答下列问题:(1)请写出该运动员剩余体力Q 关于时间t 的函数Q (t );(2)该运动员在4小时内何时体力达到最低值?最低值为多少?解:(1)由题可先写出速度v 关于时间t 的函数v(t)={30,0<t ≤130−10(t −1),1<t ≤4,代入ΔQ 1与ΔQ 2公式可得Q(t)={10000−60⋅t ⋅2×30,0<t ≤16400−60(t−1)⋅2[30−10(t−1)]t−1+1,1<t ≤4, 解得Q(t)={10000−3600t ,0<t ≤1400+1200t +4800t,1<t ≤4; (2)①稳定阶段中,Q (t )单调递减,此过程中Q (t )的最小值Q (t )min =Q (1)=6400kJ ; ②疲劳阶段Q(t)=400+1200t +4800t (1<t ≤4), 则有Q(t)=400+1200t +4800t ≥400+2√1200×4800=5200kJ , 当且仅当1200t =4800t,即t =2时,“=”成立, 所以疲劳阶段中体力最低值为5200kJ ,由于5200<6400,因此,在t =2h 时,运动员体力有最小值5200kJ .21.(12分)已知函数f (x )的定义域为R ,对任意x ,y 都有f (xy )=f (x )•f (y )+f (x )+f (y ),且x >1时,f (x )>0.(1)求f (1);(2)求证:函数f (x )在(0,+∞)上单调递增;(3)若f (﹣1)=0,f (2)=3,解关于x 的不等式f (x ﹣1)<15.解:(1)令x >1,y =1,则f (x )=f (x )f (1)+f (x )+f (1),即f (1)[f (x )+1]=0,由f (x )+1>1可知f (1)=0.(2)证明:令y =1x ,则f(x)f(1x )+f(x)+f(1x )=f(1)=0,即f(x)=1f(1x )+1−1, 若x ∈(0,1),则1x >1,所以f(x)=1f(1x )+1−1∈(−1,0). 总之,∀x >0,f (x )>﹣1.∀x 1,x 2∈(0,+∞),x 1>x 2,f(x 1)−f(x 2)=f(x 1x 2⋅x 2)−f(x 2)=f(x 1x 2)f(x 2)+f(x 1x 2) =f(x1x 2)[f(x 2)+1]>0, 所以f (x )在(0,+∞)上单调递增.(3)令y =﹣1,则f (﹣x )=f (x )f (﹣1)+f (x )+f (﹣1)=f (x ),所以f(x)为偶函数.又f(4)=[f(2)]2+2f(2)=15,当x﹣1≠0时,f(x﹣1)=f(|x﹣1|)<15=f(4),此时,|x﹣1|<4,解之得x∈(﹣3,1)∪(1,5),当x﹣1=0时,f(0)=[f(0)]2+2f(0)⇒f(0)=0或﹣1,此时f(0)<15成立,所以x=1符合不等式.综上,原不等式的解为x∈(﹣3,5).22.(12分)设函数f(x)=a x+k•a﹣x(a>0,a≠1)是定义域为R的奇函数.(1)求实数k值;(2)若f(1)<0,试判断函数f(x)的单调性,并证明你的结论;(3)在(2)的条件下,不等式f(t•9﹣|x+1|+2)+f(4•3﹣|x+1|)<0对任意实数x均成立,求实数t的取值范围.解:(1)已知f(x)=a x+k•a﹣x(a>0,a≠1),因为f(x)是定义域为R的奇函数,所以f(0)=1+k=0,解得k=﹣1,此时f(x)=a x﹣a﹣x,又f(﹣x)=a﹣x﹣a x=﹣f(x),满足函数f(x)为奇函数,所以k=﹣1;(2)证明:由(1)知f(x)=a x﹣a﹣x(a>0,a≠1),若f(1)=a−1a=a2−1a=(a+1)(a−1)a<0,可得0<a<1,则函数f(x)为减函数,任取x1<x2,此时f(x1)﹣f(x2)=a x1−a−x1−(a x2−a−x2)=a x1−a x2+a−x2−a−x1=a x1−a x2+1a x2−1a x1=a x1−a x2+a x1−a x2a x1a x2=(a x1−a x2)(1+1a x1a x2),因为x1<x2,0<a<1,所以a x1>a x2,此时a x1−a x2>0,可得f(x1)﹣f(x2)>0,即f(x1)>f(x2),所以函数f(x)在R上单调递减;(3)由(1)知f(x)=a x﹣a﹣x(a>0,a≠1),因为f(x)是定义在R上的奇函数,若不等式f(t•9﹣|x+1|+2)+f(4•3﹣|x+1|)<0对任意实数x均成立,此时f(t•9﹣|x+1|+2)<f(﹣4•3﹣|x+1|)对任意实数x恒成立,由(2)知函数f(x)在R上单调递减,所以t•9﹣|x+1|+2>﹣4•3﹣|x+1|,则t>−4⋅3−|x+1|−29−|x+1|=−4⋅3−|x+1|+23−2|x+1|=﹣2(13−2|x+1|+23−|x+1|)=﹣2(32|x+1|+2•3|x+1|)恒成立,不妨令t=3|x+1|,因为|x+1|≥0,所以t≥1,易知函数y=t2+2t(t≥1)是开口向上的二次函数,且函数在[1,+∞)上单调递增,所以当t=1时,该函数取得最小值,最小值为3,则﹣2(32|x+1|+2•3|x+1|)的最大值为﹣2×3=﹣6,故实数t的取值范围为(﹣6,+∞).。

She reached into her change purse, emptied out all the coins she had and gave them to the homeless man. Neither of them realized that this small generous act(举动) would change their lives.Sarah didn't realize that she had given Billy not only all her change but also her diamond ring that she had put in her change purse earlier until the next morning. She and her husband, Bill Krejci, rushed to see if they could find Billy. The homeless man was not only in the same place, but also immediately returned the ring. The grateful couple paid him back for his honesty by emptying out their pockets of all the money they had.Bill Krejci, a web designer, felt that he needed to do something more for this amazingly honest man. So on February 18th, he set up a special page to raise money for him. In just four days, Billy received over $85,000 and there seems to be no end yet.That is not enough. Billy is living with a person who is generous instead of living in the streets. And that’s not all thanks to the news report, he got together again with his older brother, Edwin Harris who he had been unable to find for 27 years.All the good luck is just because Billy did the right thing-returning something that did not belong to him.1.When did Sarah realize that she had also given Billy her diamond ring?A.On February 9th, 2013. B.On February l0th, 2013.C.On February 18th, 2013. D.On February 22nd 2013.2.Which of the following is NOT mentioned in the passage?A.Billy is living with a generous person.

One evening there was a big dance at the hospital. Most of the doctors and nurses would be there, but of course somebody had to be left to look after the sick children, and Joan was not of the lucky ones. She liked dancing very much, so when she had to start work that evening while her friends were getting ready to go to the dance, she felt very sorry for herself.She went to each sick child one after another and said good-night, until she came to one little boy, Dick. Dick was onlyeleven years old, but he had a very serious illness and couldn’t move most parts of his body except his hands. Joan k new Dick would never get any better, but the little boy was always happy and always thinking about other people instead of himself.Dick knew that Joan loved dancing. So when she came to say good-night to him, he greeted her with the words, “I’m very sorry that you can’t go to the dance because of us. But we are going to have a party for you. If you look in my drawer, you’ll find a piece of cake that I____from my supper today. And there is also a dollar there. You can buy something to drink with the cake.

将立到晌午时分,转来到天汉州桥热闹处去卖。
A立未久,只见两边的人都跑入河下巷内去躲。

7.综合性学习。
(7分)去年,央视播出特别节目《大国工匠》,引起热议。
某校开展“大国工匠进校园”系列活动,请你参与,并完成以下各题。
【提信息】(1)以下是同学们收集到的三则相关材料,请从中提取至少两条信息。
(2分)材料一提到优质制造,人们立刻想到:控制误差不超毫秒的瑞士钟表匠、仅拧各种螺丝就要学习几个月的德国工人、捏寿司都要捏成极致艺术品的日本手艺人……但对于更多的中国制造来说,我们仍然缺乏响当当的“中国名片”,如手机、冰箱甚至是前段时间引发抢购风潮的马捅盖等。
材料二在今年的两会上,李克强总理曾说:“我们要用大批的技术人才作为支撑,让享誉全球的‘中国制造’升级为‘优质制造’。
”材料三我国数千年历史中,出现过香班这样的大师级工匠,也有修造出故宫这种世界奇观建筑的工匠,这说明中华民族的基因里,的确有工匠精神。
《大国工匠》讲述的8个工匠,正是传承了中华民族的工匠精神,才蜂造了工匠的神话:鉴刻师孟剑锋为北京人PEC会议创作国礼“和美”纯银丝巾,坪工高风林为火箭焊“心脏”,柑工顾秋亮为“蛟龙号”装配载人深潜器……【品对联】(2)某校邀请大国工匠孟剑锋来校做演讲,书法社结合孟剑锋的事迹拟写了一副“宝剑锋从磨砺出,和美精自细琢来”的对联。
请结合材料三分析这副对联的妙处。
(答出两点即可)(3分)【言心声】(3)听了孟剑锋的演讲后.李文同学产生了学一门技艺的想法,但他的父毋极力反对。
假如你支持李文,你会如何劝说他的父母?请写出你要说的话。
(2分)二、现代文阅读(28分)(一】阅读下文,完成8一12题。
(共16分)一种真实查一路①深秋时节,我忆起在故乡的道路上行走。
清晨,白露为霜,被霜私贴的衰草,似乎成了道路衰白的茸毛。
随之,狂风劲扫,树叶落尽。
我家门前有一排柿子树,落尽绿叶,如生命脱下了华丽的袍,只剩斑驳黝黑的躯干与枯枝。
②心随之苍凉。
大地呈现出贫疥,却也在此时,一种真实显露出来,一种简陋甚至丑陋的真实—这是删繁就简之后,再也无法删除的存在。
无遮无拦,也无论你的好恶。
③渐渐地,学会去适应它,进而欣赏它。
④其实,我同样欣赏生命的裸露。
当那些被隐藏的真相,像泛黄的书卷被打开,心中或许滚过一阵惊雷.随之似乎预告这个世界的箴言被揭开—总有这样先惊后喜的感觉。
⑤读过日本小说家村上春树一篇写杰克·伦敦的短文。
⑥杰克·伦救声名鹤起之后,作为日俄战争的记者来到朝鲜半岛。
当他去往一个村庄,当地的官员到他的驻地,请求他去一个万人广场,那里有无数的民众在等待他,期待一睹他的尊容。
⑦这令杰克·伦敦颇感意外,他没有想到自己的名声不只横贯了欧美,且响遍了亚洲。
然而,他更没有想到的是,民众注意力似乎不在于他对文学的真知灼见,以及他头顶上的光环。
官吏抱歉地跟他说:对不起,我们都想看您的假牙,您能否取下您的假牙让大家看一看?⑧在村民热烈的掌声中,杰克·伦敦不怒不哄,取下假牙,向民众展示自己的假牙,时间长达30分钟。
无论此刻杰克·伦敦内心有怎样的想法,事实上,他在寒风呼啸的广场上,手拿自己的假牙向民众展示了30分钟。
⑨朴实到极致的村民,自有判别虚实的独特手段,他们用“人”的角度来观察人,想见的是作为自然人的杰克·伦敦,这就得撇开星光照耀,去端详一位名人隐藏的疤痕。
⑩换上另外一个人,这样的场景,无论如何都让人难免有些尴尬。
某个领域的光环,并不能遮掩另一方面的缺憾。
真实,必然包含着这种缺憾。
杰克·伦敦是伟大的,尊享殊荣的同时,他觉得也有义务去公布不太如意的隐私。
当然,他也有更多的理由对此讳莫如深。
(11)像深秋的大地一样坦诚,才有勇气、诚恳和担当,去揭示被自己深藏的另一面。
这种真实,挤去了泡沫、娇饰、虚华,留下无可置疑的格局、本质和分量。
或许并无美感,却有价值。
(12)深秋时节,我喜欢走在旷野.看湖水澄碧,看万木萧瑟,感受自己内心的清凉。
声气内敛的大自然沉静空旷,这样的氛围,我感知到一种回归本质的精神贯穿万物,取代繁华:一种真实—无遮无拦,不计荣辱。
8.阅读全文,请说说你对“真实”含义的理解。
(4分)9.文章开头和结尾都描写了“深秋时节”的景物,这些景物描写有什么作用?(3分)10.结合全文,品味下面句中加点词的含义。

”请结合生活实际,谈谈你对“真实价值”的认识。
(3分)(二)阅读下文,完成13-16题。
(共12分)唯有淡定才能强大无比①生活在快节奏、高频率的现代社会,我们都有一个感觉:累。
我们需要承受重重压力:学业的压力,工作的压力、生活的压力等等。
所以,时下有一句流行的话:累并痛苦着。
我们为什么会觉得痛苦,感到活得很累?因为我们有太多的欲求,太多的愿望,太多的梦想,什么都想得到,什么都不想放弃,什么都要拥有,什么都不愿舍去。
患得患失,贪得无厌,当然就很累,当然就痛苦。
②美国现代成人教育之父卡耐基在《淡定—做内心强大的自己》一书中告诉我们:唯有淡定,我们才能强大无比;唯有淡定,我们才能静观花开花落,笑看云卷云舒;唯有淡定,我们才能尽情享受生活的踢予,获得人生的幸福。
③什么是淡定?作者告诉我们,淡定就是对名利荣辱的淡然,就是对爱恨情仇的超脱,是对世态炎凉的看破。
它能让浮躁的人们学会放下,告诉人们一切顺其自然便能宁静致远;它让人们在淡定中滋养心灵,在智慧中升华人生。
心怀淡定之心的人,必将是最坦然、最和平、最洒脱的人。
④古往今来,凡是有所成就者无不具有“宠辱不惊”的宝贵品格。
莫言在获得诺贝尔文学奖后.各种评论纷至杏来。
莫言超然地说:“起初,我还以为大家争议的对象是我,渐渐地,我感到这个被争议的对象,是一个与我毫不相关的人。
我如同一个看戏的人,看着众人表演,我看到那个得奖的人身上落满了花朵,也被掷上了石块.泼上了污水,我生怕他被打垮,但他微笑着从花朵和石块中钻出来,擦干净身上的脏水,坦然地站在一边。
”这就是淡定,处世的智慧。
⑤怎样才能保持淡定,做有智慧的人呢?有智慧的人能够正确面对宠辱得失,无论世间如何变化,无论人生经历怎样的风雨,内心总能风平浪静。
有智慧的人,是懂得生活辫证法的人,知道有所得必有所失,拥有的同时也会失去,必须学会放弃。
有智慧的人,是自信的人,相信“天生我材必有用”,能够自己掌拉自己,不会被别人的议论所左右。
有智慧的人,懂得调节自己的心情,保持良好的心态,不会因打翻牛奶而影响好心情。
有智慧的人,也是懂得宽容的人,既宽容自己,宽容失致,也宽容别人,宽容错误,深知原惊别人就是解脱自己。
⑥世间一切烦恼都是自找的。
一个人能否成功,并不取决于别人怎样看待自己,而在于自己怎样看待自己。
无论面对怎样的生活景况,无论生活带给我们什么样的痛苦,必须始终记住:影响我们生活的不是处晚,不是身份,而是我们的心垅。
一定要让自己的心情保持永远的杨快。
“淡定”被手为洗涤内心污秽,解除心灵束缚,自我救助,还原幸福的心灵修行宝典。
⑦总之,淡定,是一种生活态度,一种思想境界,一种豁达人生一种成熟心态。
唯有内心淡定,我们才能强大无比,让我们学会淡定吧,珍惜人生,享受快乐,追求幸福。

三、古诗文阅读(14分)(一)阅读下面两个语段.完成17一20题。
(共II分)【甲】环滁皆山也。
其西南诸峰,林壑尤美,望之漪然而深秀者,琅琊也。
山行六七里,渐闻水声潺潺而泻出于两峰之间者,酿泉也。
峰回路转,有亭翼然临于泉上者,醉翁亭也。
