These trips weren’t the 36 vacations that last for roughly two weeks and 37 hurrying from one destination to the next. 38 , I was completely absorbed in the culture, staying in both Indonesia and China for approximately 6 weeks.After two continuous years of 39 to the Asian countries, however, I’m staying at home.My desire to travel, 40 , makes me incredibly impulsive(冲动的). One day, I was watching my old friend Andrew Zimmern travel to Cambodia. I watched him taste the special foods and 41 down a massive man-made lake, staying with locals trying to find dinner.

As I walked across the stage, reaching out for my high school principal’s hand with my right and taking my 46 with my left, I graduated. As I walked across the stage, suddenly I realized I had just completed one of the most important 47 in my life. I was soon entering the real world, but I had one last summer that see-sawed in between the real world and the world my 48 and I had just left. I had one last summer to make memories with high school friends that I 49 recall during old age.50 , I am pleased to say I have found a job this summer. I work at the Seneca Hill Animal Hospital and Resort where I look after dogs whose owners have left for summer vacation.

Which buttons directly control the movement of the Rocket Ball?A. LAUNCH and FLIPPERSB. STAR and FLIPPERSC. START/PAUSE and FLIPPERSD. LAUNCH and SELECT57. The most action-packed variation would be__________.A. Game One with a blue starB. Game Two with a black starC. Game One with a yellow starD. Game Two with a red star58. Rocket Ball could best be described as a game of__________.A. space voyageB. quick responseC. skills & strengthD. scientific knowledgeBThe Harry Potter author JK Rowling has shared some rejection letters publishers sent to her alter ego Robert Galbraith, in an effort to comfort aspiring authors.Rowling posted the letters on Twitter after a request from a fan. They related to The Cuckoo’s Calling, her first novel as Galbraith. But Rowling also saw Harry Potter turned down several times before the boy wizard became one of the greatest phenomena in children’s literature, with sales of more than 400m copies worldwide.Asked how she kept moti vated, she tweeted: ―I had nothing to lose and sometimes that makes you brave enough to try.‖ When she pitched under the name Galbraith without revealing her true identity, she faced many more snubs. Since then, Galbraith has published three successful novels but the first was rejected by several publishers, and Rowling was even advised to take a writingcourse.Rowling erased the signatures when she posted the letters online, saying her motive was ―inspiration not revenge‖. She did not reveal the full text of the most brutal brush-off, which came by email from one of the publishers who had also rejected Harry Potter.Rowling said she could not share the Potter rejections because they ―are now in a box in my attic‖ before offering the Galbraith letters. The kindest and most detailed rejection came from Constable & Robinson, who – despite the advice about a writing course – included helpful tips on how to pitch to a publisher (―as on book jackets –don’t give away the ending!‖). The publisher added: ―I regret that we have reluctantly come to the conclusion that we could not publish it without commercial success.‖ The short note from publishers Crème de la Crime said the firm had become part of another publishing group and was not accepting new submissions.When The Cuckoo’s Calling eventually found a publisher in 2013, it was achieving respectable sales before the secret of its authorship broke, and it then shot to the top of the bestseller lists. Joanne Harris, author of a string of hit novels, joined the Twitter discussion to say she had so many rejections for her 1999 book Chocolat, later adapted as a Hollywood movie, that she had piled them up and ―made a sculpture‖.Rowling, Harris and their literary disciples are in excellent company. Eimear McBride, the 2014 Bailey’s prizewinner for her first novel A Girl is a Half-formed Thing, accumulated a drawer full of rejection letters before a chance conversation led to her book being published by Galley Beggar,a tiny independent publisher in Norwich.59. Which of the following is the name of a prize for fiction?A. Robert Galbraith.B. Chocolat.C. Bailey’sD. Crème de la Crime60. JK Rowling’s novels were rejected for the following reasons EXCEPT that _________.A. the writer needs to learn some techniques about how to writeB. books are meant to be published for bringing in moneyC. the publisher for the time being denies new submissionsD. those that can be adapted for movies are worth considering61. Why did JK Rowling post some rejection letters on the Twitter?A. To inform readers that hardships make a man stronger.B. To inspire ambitious writers never to give up halfway.C. To take her revenge on those publishers who ever rejected her.D. To carry out an academic discussion with other fellow writers.CTwo things that Starbucks has discovered about mothers: first, our bodies are 90 per cent made up of milky coffee, which requires constant refilling; and second, we very much want to be wanted. Hence, its new ―parent-friendly‖ pledge.With the help of the National Childbirth Trust, baristas at more than 800 Starbuck outlets around Britain are being trained in how to handle tired and emotional parents. Breastfeeding will be encouraged; bottles will be warmed on request; high chairs and changing tables will be supplied in abundance; there will even be emergency nappies on hand, for when your baby’s having one of those hundred-poo days and you only packed supplies for 99. ―It’s important that parents feel reassured they have the support of staff and won’t be judged,‖ says an NCT spokeswoman.In return for these efforts, Starbucks branches will be able to display a special NCT window sticker bearing the logo: ―Parent Friendly Place.‖ This has t he double advantage of implying that other cafes, lacking the official sticker, might be Parent Unfriendly, or at least a little Parent Standoffish. And indeed, some are. Who can blame them? Where there are parents, there are children – crying, running about, pouring out salt into little mounds, sucking their fingers and then sticking them in the sugar bowl.On the other hand, there’s always money to be made from society’s desperate. Catering to parents, literally or figuratively, makes sense for those businesses already paying rents on the high street. It brings in customers all through the day, instead of just at lunch and supper. Cinemas have cottoned onto this too: the big chains have all introduced daytime ―parent and baby‖ screenings, where you and your screaming bundle of reflux can pretend to watch a whole grown-up film and no one is allowed to tut.Even the swankiest restaurants are getting in on the act. The Michelin-starred Pollen Street Social in London, and the equally feted Delaware and Hudson in New York, have both hosted ―dining clubs for mothers‖. You take your child along with you to eat posh food from posh plates, and pretend the last two years of living off cold fish fingers and squirts of Ella’s Kitchen straight from the sachet were just a bad dream.There is, I can’t help feeling, something slightly depressed about all this. Why are we so reluctantto give up our old habits? Is it because so many of us come to motherhood late, by which time our habits have come to define us? I remember, soon after having my first child, fretting that I had ―lost myself‖, as if I’d left my ID somewhere along with my car keys. I tried all sorts of things to recover it: spa weekends with girlfriends, date nights with the husband, writing book proposals in a vain attempt to restart my ambition.But, after eight years and two more children, I have come to realise –you can’t ever get your old life back. It’s no use looking for it in restaurants and cinemas and down the back of the sofa. That person – the one who could leave the house without having to hire someone to take her place, and gossip at leisure without being tugged at on all sides by tiny, insistent hands, like a bosomy, Breton-striped Gulliver –is no more. And the strangest thing is, you don’t even mi ss her.62. How do you understand the sentence ―We very much want to be wanted" in the first paragraph?A.Mothers want society to be considerate of the uniqueness of their identity.B.Mothers hope to get rid of traditional roles and go to work.C.Mothers expect their kids to think of them frequently when they grow up.D.Mothers desire to have the same social position as men.63. Which of the following measures is used to attract mothers to restaurants?A.Some businesses pay rents on the high street.B.Free spa weekends and date nights are provided for them.C.They can enjoy cold fish fingers and squirts of Ella’s kitchen in restaurants.D.Dining clubs are hosted and nappies are even supplied on request.64. Which of the following has the closest meaning to the underlined phrase ―getting in on the act‖?A. responding accordinglyB. joining the lineup of businessC. taking the critical attitudeD. preventing the act happening65. Which is the best title for the passage?A. Mother’s New Appeal: Cozier LifeB. A Study on Mothers’ Likings and DislikingsC. Easy Money from New ParentsD. On Restaurants’ Marketing StrategiesDIn the film The Revenant the Leonardo DiCaprio adventuretakes the basic facts of real-life frontiersman Hugh Glass'ssufferings and adds extra characters, extra ultra violence andmore horse guts.Hugh Glass was a frontiersman working in the upper Missouririver area in the early years of the 19th century. On a fur trapping expedition in 1823, he was attacked and injured by a grizzly bear.1. _____________Hugh Glass (Leonardo DiCaprio) is one of a group of men finishing up a fur trapping expedition in the wilderness. They are attacked by Ree (Arikara) warriors. Whoosh!Someone gets impaled on a spear. Bang!Someone gets shot off his horse. Crack!Someone's bones shatter. There's a fearless close-up of an arrow thwacking into a face, a gun butt bashing into a face, a flying kick to a face. A horse gets shot in the face. It's exceptionally well choreographed (取景) and filmed. This scene is based on a real-life incident: In June 1823, Ashley's band of around 70 men was attacked by Arikara warriors –they estimated around 600, though in the film it's more like a dozen.2. CharactersIn the film, 10 men get away. Fitzgerald is fighty and racist, so he's the bad guy. Glass is the good guy, because he loves his son (who is half-Pawnee) in a gruff, manly way that involves telling him off a lot. The back story abo ut Glass’s love for a Pawnee woman is fiction. It has been suggested the real Glass had such a relationship, but there's no firm evidence –and no evidence that he had any children.3. WildlifeAs the men make their way through a forest, Glass happens upon two bear cubs and their angry mama. If you felt pale after the face-smashing scene at the start, reach for the smelling salts. Chomp!Growl!Shake!The bear sniffs him to see if he's dead, then jumps up and down on his back. Splinter!Howl!Slash!Glass shoots the bear. Anyway, while historians are not certain of the precise details, the real Glass did get into a fight with a real bear, sometime in August 1823. 4. MurderThe men find Glass in a rum old state. Captain Henry pays Fitzgerald, Bridger and Hawk to staybehind until it is time for Glass's inevitable burial. When the captain leaves, Fitzgerald tries to bump Glass off. Hawk interrupts, so Fitzgerald bumps him off instead. This didn't happen in real life, because Hawk didn't exist. In the film, the weak Glass sees Fitzgerald kill his son, giving him an extra motivation to stay alive and seek revenge.5. SurvivalThe real Glass survived his abandonment and dragged his battered body over hundreds of miles of terrain in pursuit of the men who left him for dead. Though he could read and write, Glass never set his story down in his own hand. It was first published by another writer in a Philadelphia journal in 1825. It may well have been modified then. It has been modified many times since.6. HardshipThe film has invented some extra obstacles for Glass: it is snowing throughout, even though in real life his trek took place between August and October; the Arikara track him and chase him into a tree; he has to hollow out a dead horse to make himself a sleeping bag. As for the ending, it has been changed in one significant way: in real life, nobody got killed.66. We can know for sure after reading the passage that real Hugh Glass _____.A. finally survived for he was determined to take revenge on Fitzgerald killing HawkB. fell in love with a Pawnee woman and soon after they had a clever and brave boyC. wrote nothing about his suffering despite the fact that he was actually educatedD. nearly got killed by Fitzgerald and Hawk under the instruction of Captain Henry67. To play the role of Hugh Glass, Leonardo DiCaprio must have ______.A. fought against three bears courageouslyB. walked in snow with great difficultyC. rode a horse time and time againD. grasped skills for surviving in the wild68. Which of the following can be the best subtitle for the 4th and 5th paragraphs?A. ViolenceB. SettingC. HorrorD. Special effects69. We can see here and there in the passage that the writer thinks of the movie as a _____ adaptation.A. faithfulB. disappointingC. successfulD. heartless70. The passage is intended to inform readers _____.A. how tragic Hugh Glass's experience isB. how well Leonardo DiCaprio performs in The RevenantC. how bloody the movie The Revenant isD. how historically accurate The Revenant is第四部分任务型阅读(共10小题,每小题1分,满分10分)请认真阅读下列短文,并根据所读内容在文章后表格中的空格里填入一个最恰当的单词。

深受道禅哲学影响的倪云林、陈老莲乃至后来八大山人、渐江等的绘画不是“看世界活”,而是“让世界活”:不是从形式美感入手,画出一个活的世界,而是让人放弃对物质形式的执着,通过寂寥境界的创造,荡去遮蔽,让世界自在活泼——虽然没有活泼的物质形式,却彰显了世界本原的真实,所以它是活的。

当m ≠-2,n ≠0时,直线FP 的斜率为nm +2,直线FP 的方程为y =nm +2(x +2). 故直线AO 的方程为y =-m +2n x ,Q 点的纵坐标y Q =2n (m +2)(m +2)2+n 2.…………………………………………………5分所以FP FQ =|ny P |=|(m +2)2+n 22(m +2)|=|(m +2)2+1-m 252(m +2)|=|4m 2+20m +2510(m +2)|.令FP FQ =110,得4m 2+21m +27=0 ①,或4m 2+19m +23=0 ② . ………………………7分由4m 2+21m +27=0,解得m =-3,m =-94,又-5≤m ≤5,所以方程①无解.由于△=192-4×4×23<0,所以方程②无解,故不存在点P 使FP FQ =110.………………………………………………………………10分(3)设M (x 0,y 0),A (-a 2c ,t ),则FM →=(x 0+c ,y 0),OA →=(-a 2c ,t ).因为OA ⊥FM ,所以FM →·OA →=0,即(x 0+c )(-a 2c )+ty 0=0,由题意y 0≠0,所以t =x 0+c y 0·a 2c .所以A (-a 2c ,x 0+c y 0·a 2c).……………………………………………………12分因为AM →=(x 0+a 2c ,y 0-x 0+c y 0·a 2c ),OM →=(x 0,y 0),所以AM →·OM →=(x 0+a 2c )x 0+(y 0-x 0+c y 0·a 2c )y=x 02+y 02+a 2c x 0-x 0+c y 0·a 2c y 0 =x 02+y 02+a 2c x 0-a 2cx 0-a 2 =x 02+y 02-a 2. 因为M (x 0,y 0)在圆O 上,所以AM →·OM →=0. ………………………………………………15分 即AM ⊥OM ,所以直线AM 与圆O 相切. 同理可证直线AN 与圆O 相切.……………………………………………………16分19.解:(1)当a =0时,f (x )=x ln x -x ,f’(x )=ln x , 令f’(x )=0,x =1,列表分析故f (x )的单调递减区间为(0,1),单调递增区间为(1,+∞). …………………………3分(2)f (x )=(x -a )ln x -x +a ,f ’(x )=ln x -ax ,其中x >0,令g (x )=x ln x -a ,分析g (x )的零点情况.g ’(x )=ln x +1,令g ’(x )=0,x =1e,列表分析g (x )min =g (1e )=-1e-a ,…………………………5分而f’(1e )=ln 1e -a e =-1-a e ,f’(e -2)=-2-a e 2=-(2+a e 2),f ’(e 2)=2-a e 2=1e2(2e 2-a ),①若a ≤-1e ,则f’(x )=ln x -ax ≥0,故f (x )在(e -2,e 2)内没有极值点;②若-1e <a <-2e 2,则f’(1e )=ln 1e -a e <0,f’(e -2)=-(2+a e 2)>0,f’(e 2)=1e2(2e 2-a )>0, 因此f’(x )在(e -2,e 2)有两个零点,f (x )在(e -2,e 2)内有两个极值点;③若-2e 2≤a <0,则f’(1e )=ln 1e -a e <0,f’(e -2)=-(2+a e 2)≤0,f’(e 2)=1e 2(2e 2-a )>0,因此f’(x )在(e -2,e 2)有一个零点,f (x )在(e -2,e 2)内有一个极值点; 综上所述,当a ∈(-∞,-1e]时,f (x )在(e -2,e 2)内没有极值点;当a ∈(-1e ,-2e2)时,f (x )在(e -2,e 2)内有两个极值点;当a ∈[-2e2,0)时,f (x )在(e -2,e 2)内有一个极值点.. ………………………10分(3)猜想:x ∈(1,1+a ),f (x )<a -1恒成立. ……………………………………………11分 证明如下:由(2)得g (x )在(1e,+∞)上单调递增,且g (1)=-a <0,g(1+a )=(1+a )ln(1+a )-a .因为当x >1时,ln x >1-1x (*),所以g(1+a )>(1+a )(1-1a +1)-a =0.故g (x )在(1,1+a )上存在唯一的零点,设为x 0.由知,x ∈(1,1+a ),f (x )<max{f (1),f (1+a )}. …………………………………………13分 又f (1+a )=ln(1+a )-1,而x >1时,ln x <x -1(**), 所以f (1+a )<(a +1)-1-1=a -1=f (1). 即x ∈(1,1+a ),f (x )<a -1.所以对任意的正数a ,都存在实数t =1,使对任意的x ∈(t ,t +a ),使 f (x )<a -1.……………………………………………15分补充证明(*):令F (x )=ln x +1x -1,x ≥1.F ’(x )=1x -1x 2=x -1x2≥0,所以F (x )在[1,+∞)上单调递增. 所以x >1时,F (x )>F (1)=0,即ln x >1-1x .补充证明(**)令G (x )=ln x -x +1,x ≥1.G ’(x )=1x-1≤0,所以G (x )在[1,+∞)上单调递减.所以x >1时,G (x )<G (1)=0,即ln x <x -1. ……………………………………………16分20.解:(1)设所求等比子数列含原数列中的连续项的个数为k (1≤k ≤3,k ∈N *),当k =2时,①设1n ,1n +1,1m 成等比数列,则1(n +1)2=1n ×1m ,即m =n +1n +2,当且仅当n =1时,m ∈N *,此时m =4,所求等比子数列为1,12,14;②设1m ,1n ,1n +1成等比数列,则1n 2=1n +1×1m ,即m =n +1+1n +1-2 N *;…… 3分当k =3时,数列1,12,13;12,13,14;13,14,15均不成等比,当k =1时,显然数列1,13,15不成等比;综上,所求等比子数列为1,12,14. ………………………………………………………5分(2)(i )形如:a 1,-a 1,a 1,-a 1,a 1,-a 1,…(a 1≠0,q =-1)均存在无穷项等差子数列: a 1,a 1,a 1,… 或-a 1,-a 1,-a 1, ……………………………………7分(ii )设{a n k}(k ∈N *,n k ∈N *)为{a n }的等差子数列,公差为d , 当|q |>1时,|q |n >1,取n k >1+log |q ||d ||a 1|(|q |-1),从而|q |n k-1>|d ||a 1|(|q |-1),故|a n k +1-a n k|=|a 1qn k +1-1-a 1qn k -1|=|a 1||q |n k -1·|qn k +1-n k-1|≥|a 1||q |n k -1(|q |-1)>|d |,这与|a n k +1-a n k|=|d |矛盾,故舍去;
