A new trend is taking hold in China — guochao, or “China-chic”.The term characterizes the rise o f China’s native fashion trends. It has expanded the concept of “Made in China”, which has been recognized as the representation of Chinese culture and aesthetics (美学) offered by homegrown Chinese brands.China-chic came into the spotlight in 2018. Before that, big-name foreign companies, such as NIKE, ADIDAS and PUMA, dominated the world market. But that year, Chinese sportswear brand Li-Ning changed things up. During the 2018 New York Fashion Week, Li-Ning introduced its Taoism-inspired Wu Dao collection. The collection not only had a trendy look, but also included elements of traditional Chinese culture. It immediately grabbed attention at home and abroad. As a result, the company recorded 20 percent profit growth in 2018, marking the first time the brand’s revenue had hit the 10-billion-yuan mark since its founding.The trend to embrace domestic brands has since spread rapidly to various sectors and products, from food and drinks to clothing, mobile phones and electric vehicles. For example, White Rabbit, whose sweet candy brings back childhood memories for many, launched its perfume and lip balm. “We want White Rabbit to be a brand that young people want to share,” said Shen Qinfeng, the company’s marketing manager.Now, the guochao trend is “moving to th e next stage, where its success will rely, first and foremost, on gaining cultural confidence rather than Western recognition.” according to Kerra Zhou, founder of brand strategy consultancy Kerrisma. No matter how the guochao trend develops, there’s onet hing that won’t change: Behind the craze is people’s positive attitude toward the country’s development and their recognition of growing confidence in national culture, added Zhou.4. What’s the function of Paragraph 1?A.To introduce a new trend in China.B.To highlight the popularity of guochao.C.To describe a common scene on the street.D.To show Chinese brands beat foreign companies.5. Which of the following statements about guochao is correct?A.Li-Ning stimulated the development of guochao.B.Guochao is a new trend popular throughout the world.C.Guochao refers to people’s preference for ancient culture.D.It’s before 2018 that guochao had received great attention.6. What may Kerra Zhou agree with?A.Chinese is still following the western trend.B.Guochao’s success relies on western recognition.C.National pride arouses the passion for guochao.D.Cultural awareness is the key to winning market share.7. Which can be a suitable title for the text?A.The Popularity of Native Brands B.The Boom of China-chicC.The Recognition of National Culture D.The Root of GuochaoAutomation (自动化) was a hot topic. Nearly everyone agreed that people would be working less once computers and other kinds of automatic machinery became widespread. For optimists, this was a promise of liberation: At last humanity would be freed from constant toil, and we could all devote our days to more refined pursuits. But others saw a threat: Millions of people would be thrown out of work, and desperate masses would roam the streets. Looking back from 50 years hence, the controversy over automation seems a quaint and curious episode. The dispute was never resolved.A. J. Hayes, a leader(and no relation to me), wrote in 1964: Automation is not just a new kind of mechanization but a revolutionary force capable of overturning our social order. Whereas mechanization made workers more efficient-and thus more valuable-automation threatens to make them superfluous (过剩的)-and thus without value. The opinions I have cited here represent extreme positions, and there were also many milder views. But I think it’s fair to say that most early students of automation, including both critics and enthusiasts, believed the new technology would lead us into a world where people worked much less.As for economic consequences, worries about unemployment have certainly not gone away-not with job losses in the current recession approaching 2 million workers in our country alone. But recent job losses are commonly attributed to causes other than automation, such as competition from overseas or a roller-coaster financial system. In any case, the vision of a world where machines do all the work and people stand idly by has simply not come to pass.The spread of automation outside of the factory has altered its social and economic impact in some curious ways. In many cases, the net effect of automation is not that machines are doing work that people used to do. Instead we’ve dispensed with the people who used to be paid to run the ma-chines, and we’v e learned to run them ourselves. These trends contradict almost all the expectations of early writers on automation, both optimists and pessimists. So far, automation has neither liberated us from the need to work nor deprived us of the opportunity to work. Instead, we’re working more than ever.What about trades closer to my own vital interests? Will science be automated? Technology al-ready has a central role in many areas of research; for example, genome sequences could not be read bytraditional lab-bench methods. Replacing the scientist will presumably be a little harder than re-placing the lab technician, but when a machine exhibits enough curiosity and tenacity, I think we’ll just have to welcome it as a companion in zealous research. And if the scientist is elbowed aside by an automaton, then surely the science writer can’t hold out either. I’m ready for my 15-hour work-week.8. In Paragraph 1, the writer mainly wants to convey that .A.automation results in unemployment onB.automation does more harm than goodC.the issue of automation is still in discussionD.automation brings in much convenience in life9. According to A. J. Hayes, we can infer .A.automation is more valuable than what we imagineB.automation is a revolutionary force to better developmentC.the disadvantages of automation far outweigh the advantagesD.the new technology would lead people into working much less10. What does the underlined word possibly mean?A.Put. . . down for. B.Set. . . free from.C.Bring. . . into. D.Take. . . away from.11. What can we conclude from this passage?A.People needn’t work so hard due to automation.B.Traditional labor force will be replaced in the near future.C.Automation should be accepted reasonably in development.D.Automation r esults in more job losses in the writer’s country.Artificial cloud technology could soon be used in the fight against environmental damage. Researchers in Australia have used machines to spray salt water into the air, and noted that the reflective qualities of these artificial clouds helped protect the Great Barrier Reef from sun bleaching (漂白).The so-called cloud brightening project works by thickening existing clouds and reducing sunlight exposure to protect the reef. No artificial chemicals make it into the clouds in the sky. When water droplets steam, they leave only small salt crystals that float up into the atmosphere. This provides a larger surface area for water vapor to be liquids around them, forming thicker clouds.The past two years have seen uncommon forest fires and droughts triggered by the climate change emergency, meaning that widespread use of this technique may become more commonplace if carbon emissions are not checked.Drones, unmanned flying vehicles, have also entered the cloud controlling picture, used in the United Arab Emirates, a country desperately in need of more rainfall, to deliver electrical shocks to clouds in order to facilitate rainfall. Zapping (击打) clouds to produce a positive or negative charge within clouds can cause water droplets to form together. The greater the charge, the larger the droplets, which is vital for ensuring that as much rain as possible reaches the surface before steam gives off all the hard-won moisture (水分).Even if one waves aside climate change, global waterfall shortages are still an increasing concern, given the planet’s booming population. More people means more mouths to feed, and the demand for water in agriculture for animals and crops further increases urgency for cloud controlling technology. An increase in rain also leads to positive economic growth in many countries, as large harvests stabilize financial systems and living standards in all climates.Increasingly, scientists are looking to our skies in providing solutions to protect our environment. Cloud controlling technologies have promise. However, for this field of science to become practical economically, more research needs to be done in making this process a practicable option in protecting our environment.12. How does the cloud brightening project work?A.By creating more water vapor which later becomes liquids.B.By spraying chemicals and small salt crystals into the atmosphere.C.By expanding the water vapor arca and blocking more sunlight.D.By steaming water droplets to provide a larger surface area.13. What do we know about drones from paragraph 4?A.They spread larger water droplets.B.They charge clouds to promote rain.C.They will be popularized in dry years.D.They control the movements of clouds.14. What is paragraph 5 mainly about?A.Problems of overpopulation.B.Solutions to waterfall shortage.C.Urgency of economic development.D.Additional benefit of cloud technology.15. Which aspect does the author think should be improved?A.High cost.B.Research method.C.Environmental impact.D.Complicated process.We all regard receiving presents as a pleasant experience and yet it can be one of the most embarrassing situations. 16All you can do is exchange it after your friend or relative has gone home. 17 Worse still, the agreement on the sale is between the person who bought it and the shop.So you will have to tell your favourite aunt that the T-shirt does not fit. But an exchange is not always that simple because there has to be a good reason for it. 18 For example, if the buyer was told that a switch was voice-operated and later found out it was not, then action could be taken. You would have the right to return it and get the money back.Many big stores have a much more tolerant policy towards return and see it as a gesture of good will to exchange goods without question. Stores including Marks & Spencer are well-known for their “no argument” policy on returned goods. However, shoppers sho uld remember this is a privilege, not a right.So if a shop refuses to exchange the goods or to offer a refund, the seller is likely to be within his legal rights unless there is something wrong with the goods. 19 You have every right to demand a cash r efund or a replacement, but only if you have returned it within a “reasonable” time.20 Some shops and stores expect things to be returned within a week of purchase, while others may permit a much longer time limit. In any case, if you return a thing after what is considered a “reasonable” time, then all you are legally entitled to is the cost of repair.The recently concluded 19th Asian Games were _______ the most spectacular sporting event of the year, with 15 world records broken.The Games featured 11, 830 athletes from 45 Asian countries and regions who _______ in Hangzhou, Zhejiang province, to _______ for 481 gold medals in 40 sports at 56 competition venues.These 45 countries _______ 55 percent o f the world’s population.

对于D ,当x ∈(0,+∞)时,f (x )=1x+1,其图像是由反比例函数y =1x 向左平移1个单位而得, 图象是单调递减的曲线且以x 轴为渐近线,可知f (x )是凹函数, 可知∀x 1,x 2∈(0,+∞),都有f(x 1+x 22)≤f(x 1)+f(x 2)2成立,故D 正确. 故选:ACD .三、填空题:本题共4小题,每小题5分,共20分.13.若幂函数f (x )=x α(α∈R )是奇函数,且在(﹣∞,0)上单调递减,则α的值可以是 .(只要写一个即可) 解:当α=﹣1时,则f (x )=1x为奇函数,且在(﹣∞,0)上单调递减,符合题意. 故答案为:﹣1(答案不唯一).14.命题“∃x >1,x 2<1”的否定为 . 解:“∃x >1,x 2<1”的否定为:∀x >1,x 2≥1. 故答案为:x >1,x 2≥1.15.函数f (x )=[x ]的函数值表示不超过x 的最大整数,例如,[﹣3.5]=﹣4,[2.1]=2,若集合A ={y |y =[2x 2−3x 2+1],x ∈R },则A 中元素的个数是 . 解:∵2x 2−3x 2+1=2(x 2+1)−5x 2+1=2−5x 2+1,x 2+1≥1,0<5x 2+1≤5,∴−3≤2−5x 2+1<2, ∴−3≤2x 2−3x 2+1<2, ∴A ={﹣3,﹣2,﹣1,0,1},A 中元素的个数为5. 故答案为:5.16.已知函数f (x )=﹣x +2,g (x )=x 2+5x+10x+3+m ,若对任意x 1∈[1,2],存在x 2∈(﹣2,3),使得f (x 1)=g (x 2),则实数m 的取值范围 .解:∵f (x )=﹣x +2为减函数,∴当x ∈[1,2]时,其值域A =[0,1]; ∵x ∈(﹣2,3),∴x +3∈(1,6), 令t =x +3,则t ∈(1,6),g (x )=x 2+5x+10x+3+m ,可化为y =(t−3)2+5(t−3)+10t +m =t +4t+m ﹣1(1<t <6), 由对勾函数的性质可知,h (t )=t +4t+m ﹣1在区间(1,2]上单调递减,在区间[2,6)上单调递增, ∴h (t )min =h (2)=3+m ,又h (1)=4+m ,h (6)=173+m ,h (6)>h (1), ∴h (t )∈[3+m ,173+m ),∴当x ∈(﹣2,3)时,g (x )的值域为B =[3+m ,173+m );∵对任意x 1∈[1,2],存在x 2∈(﹣2,3),使得f (x 1)=g (x 2), ∴A ⊆B , ∴{3+m ≤0173+m >1,解得−143<m ≤﹣3.故答案为:(−143,﹣3]. 四、解答题:本大题共6小题,共70分.解答应写出文字说明、证明过程或演算步骤. 17.(10分)设全集为U =R ,集合A ={x |x <﹣3或x >5},B ={x |﹣2<x <10}. (1)求(∁U A )∩B ;(2)已知C ={x |a <x <a +1},若C ⊆B ,求实数a 的取值范围. 解:(1)因为集合A ={x |x <﹣3或x >5},B ={x |﹣2<x <10}, 所以∁U A ={x |﹣3≤x ≤5},(∁U A )∩B =(﹣2,5];(2)因为C ⊆B ,所以{a +1≤10a ≥−2,解得﹣2≤a ≤9,即a 的取值范围[﹣2,9].18.(12分)若正数a ,b 满足ab =4a +b +t ,t ∈R . (1)当t =0时,求a +4b 的最小值;(2)当t =5时,求ab 的取值范围. 解:(1)当t =0时,4a +b =ab , 所以4b +1a=1,所以a +4b =(a +4b )(1a +4b )=17+4ba +4ab ≥17+2√4b a ⋅4ab =25,当且仅当4a b=4b a且ab =4a +b ,即a =b =5时取等号;(2)当t =5时,ab =4a +b +5≥2√4ab +5,当且仅当b =4a ,即a =52,b =10时取等号, 解得ab ≥25,故ab 的取值范围为[25,+∞).19.(12分)已知二次函数f (x )=ax 2+bx +c 的图象与直线y =﹣4有且仅有一个公共点,且不等式f (x )<0的解集为[﹣1,3]. (1)求f (x )的解析式;(2)关于x 的不等式f (x )<(m ﹣1)x ﹣3﹣m 的解集中恰有两个整数,求实数m 的取值范围. 解:(1)根据题意,可得f (x )<0的根为﹣1和3,且ax 2+bx +c +4=0有两个相等的实数根, 故{−1+3=−ba −1×3=c a ,且b 2﹣4a (c +4)=0,解得a =1,b =﹣2,c =﹣3,f (x )=x 2﹣2x ﹣3;(2)f (x )<(m ﹣1)x ﹣3﹣m ,即x 2﹣2x ﹣3<(m ﹣1)x ﹣3﹣m ,整理得x 2﹣(m +1)x +m <0, 若m =1,不等式化为(x ﹣1)2<0,解集为空集,不符合题意; 若m ≠1,不等式化为(x ﹣m )(x ﹣1)<0,当m <1时,解集为(m ,1),若恰有两个整数在区间(m ,1),则﹣2≤m <﹣1; 当m >1时,解集为(1,m ),若恰有两个整数在区间(1,m ),则3<m ≤4. 综上所述,实数m 的取值范围是[﹣2,﹣1)∪(3,4].20.(12分)立德中学学生在社会实践活动中,通过对某商店一种换季商品销售情况的调查发现:该商品在过去的两个月内(以60天计)的日销售价格P (x )(元)与时间x (天)的函数关系近似满足P (x )=1+2x.该商品的日销售量 Q (x )(个)与时间x (天)部分数据如下表所示:给出以下两种函数模型:①Q (x )=a (x ﹣25)2+b ,②Q (x )=a |x ﹣30|+b .(1)请你根据上表中的数据,从中选择你认为最合适的一种函数模型来描述该商品的日销售量Q (x )与时间x 的关系,并求出该函数的解析式;(2)求该商品的日销售收入f (x )(1≤x ≤60,x ∈N *)的最小值.解:(1)模型①:Q (x )=a (x ﹣25)2+b ,x =25时,Q (25)=b =1670, x =20时,Q (20)=25a +1670=1680,解得a =0.4; 所以Q (x )=0.4(x ﹣25)2+1670;计算Q (45)=0.4×202+1670=1830>1690, Q (60)=0.4×352+1670=2160>1720;模型②:Q (x )=a |x ﹣30|+b ,表示在x =30两侧“等距”的函数值相等, 由{Q(25)=5a +b =1670Q(20)=10a +b =1680,解得a =2,b =1660, 所以Q (x )=2|x ﹣30|+1660,所以Q (45)=15×2+1660=1690,Q (60)=30×2+1660=1720; 所以利用模型②最合适,此时Q (x )=2|x ﹣30|+1660;(2)由(1)知,该商品的日销售收入f (x )=P (x )•Q (x )=(1+2x)(2|x ﹣30|+1660)={3440x −2x +1716,1≤x ≤302x +3200x+1604,30<x ≤60, 当1≤x ≤30时,f (x )是单调递减函数,最小值为f (30)=344030−60+1716≈1771, 当30<x ≤60时,f (x )=2x +3200x +1604≥2√2x ⋅3200x +1604=1764,当且仅当2x =3200x,即x =40时“=”成立,综上,f (x )的最小值是1764.21.(12分)定义:对于函数f 1(x ),f 2(x ),h (x ),如果存在实数a ,b ,使得af 1(x )+bf 2(x )=h (x ),那么称h (x )为f 1(x )和f 2(x )的生成函数. (1)给出函数f 1(x )=−14x 2−12x +154,f 2(x )=x 2﹣4x ﹣5,h (x )=x 2﹣10x +5,请判断h (x )是否为f (x )和f 2(x )的生成函数?并说明理由;(2)设f 1(x )=x (x >0),f 2(x )=1x (x >0),当a =2,b =8时,f 1(x )和f 2(x )的生成函数为h (x ).若对于任意正实数x 1,x 2且x 1+x 2=2,是否存在实数m ,使得h (x 1)h (x 2)>m 恒成立?若存在,求出m 的最大值;若不存在,请说明理由.解:(1)h (x )是f 1(x ),f 2(x )的生成函数,理由如下:若h (x )是f 1(x ),f 2(x )的生成函数,则存在实数a ,b 使得h (x )=af 1(x )+bf 2(x )成立, 所以x 2−10x +5=a(−14x 2−12x +154)+b(x 2−4x −5),即{ −14a +b =1−12a −4b =−10154a −5b =5,解得a =4,b =2, 所以h (x )是f 1(x ),f 2(x )的生成函数.(2)f 1(x )=x (x >0),f 2(x)=1x (x >0),当a =2,b =8时的生成函数ℎ(x)=2x +8x, 假设存在实数m ,使得对任意正实数x 1,x 2,满足x 1+x 2=2,h (x 1)h (x 2)≥m 恒成立, 所以ℎ=ℎ(x 1)ℎ(x 2)=4x 1x 2+64x 1x 2+16(x 1x 2+x2x 1)=4x 1x 2+64x 1x 2+16[(x 1+x 2)2x 1x 2−2]=4x 1x 2+128x 1x 2−32,令t =x 1x 2,t =x 1x 2≤(x 1+x 22)2=1, 因为ℎ=4t +128I−32在(0,1]单调递减, 所以h 的最小值为100,所以m 的最大值为100. 22.(12分)已知f (x )=x (|x ﹣4a |+2),a ∈R . (1)若f (1)=3,判断f (x )的奇偶性;(2)若f (x )在[1,3]上的最小值是3,求正数a 的值. 解:(1)根据题意,f (x )=x (|x ﹣4a |+2),其定义域为R , 若f (1)=3,即|1﹣4a |+2=3,解得a =0或a =12, 当a =0时,f (x )=x |x |+2x ,因为f (﹣x )=﹣x |﹣x |﹣2x =﹣x |x |﹣2x =﹣f (x ),所以f (x )是奇函数, 当a =12时,f (x )=x |x ﹣2|+2x ,所以 f (﹣1)=﹣5,f (1)≠f (﹣1),f (1)≠﹣f (﹣1), 所以f (x )既不是奇函数,也不是偶函数; (2)由题意得f (x )={x 2−(4a −2)x ,x ≥4a −x 2+(4a +2)x ,x <4a,对于f (x )=x 2﹣(4a ﹣2)x ,其对称轴为x =2a ﹣1,开口向上, 对于f (x )=﹣x 2﹣(4a +2)x ,其对称轴为x =2a +1,开口向下, 又由f (x )在[1,3]上的最小值是3,则有f (1)=|1﹣4a |+2≥3, 解可得a ≤0或a ≥12,又由a为正数,则a≥1 2,当a=12时,f(x)=x|x﹣2|+2x,易得f(x)在[1,3]上递增,且f(1)=3,符合题意;当a>12时,有4a>2a+1>2a﹣1,f(x)在(﹣∞,2a+1]单调递增,在[2a+1,4a]单调递减,在[4a,+∞)单调递增.有1<2a+1且f(4a)=8a>4>3,则f(x)在[1,3]上的最小值只能在x=1处取到,但f(1)=4a+2>3,与之矛盾;故a>12不符合题意,综合可得:a=1 2.。
