L osing m yself i n p ainting f illed m e w ith p eace. P ainting p rovidedme with the only place where I could escape from those threatening words.When I was twenty-one, my right eye went blind. Precisely three months after my twenty-fifth birthday, I had a massive hemorrhage (大出血) in my left eye because ofan accident. For the next twenty years, vision came and went. I went through many eyeoperations in an attempt to keep my vision. But after one final operation, I lost the battle and all remaining vision. And I buried all dreams of painting.Desperate, I enrolled in (注册) a sixteen-week program for the blind and visually impaired (损伤的). I learned personal adjustment and the use of a computer with adaptive software. A whole new world opened up to me through this program.“Jaws and Window-Eyes are leading software for the blind,” my instructor told me. “You c an u se t he I nternet, e-mail a nd M icrosoft w ith a ll i ts t ools a nd f eatures.”It’s amazing! Hope went up for the first time in years. “By learning how to use hotkeys to control the mouse, you can use Microsoft Access, Excel and Powerpoint,” my instructor added.For t he n ext s everal y ears, I l earned t hat w hen o ne d oor c loses, a nother d oor o pens.

At days end, reporters from different nations would share notes on what they had observed all over the grounds. Twenty-seven years later, the press room has touch screens that allow us to watch live videos from any court, and even go back to watch key moments in key matches long after they have finished. You could cover Wimbledon without leaving your seat. But that is a bit like spending all your time ordering room service and looking up funfacts on Wikipedia.More than at any other tennis tournament, there is also a n appetite for stories thatdeal with the setting, the history and the traditions.If they change the price of the fish tacos (鱼肉卷饼) at the United States Open,it’s n ot a s tory.

It’s time to email your editor using capital letters.The new retractable (可伸缩的) roof was put in place in 2009. U ntil then, you always had to have a rainy-day story in your notebook because there were no guarantees any matches would be played. Now tennis is a sure thing on Centre Court, which has made tennis reporters a bit less creative. But at least it guarantees us daily access tothe most atmospheric place in the sport.So much has changed, but Centre Court remains true to its original spirit: more a theater than a stadium.

The regulation that applies to supermarkets over 4,000 square f eet r equires s tores t o s ign o fficial d onation a greements w ith l ocal f ood b anks.The law also makes it illegal for stores to pour water over nearly-expired food,or s tore i t i nside l ocked w arehouses u ntil i t i s p icked u p b y t he g arbage t rucks. T hese measures are often undertaken by supermarkets to prevent the hungry from searching for food through the dustbins.Though that may appear cruel, the stores claim they do it to avoid potential food poisoning that could occur if the product is on its way past its expiry. Those whodo not obey the new law face the risk of heavy fines.Also, excess goods like yogurt or milk that are likely to go bad quickly are now allowed t o b e d onated d irectly t o t he f ood b anks. T hough t his h as a lways b een p ossible, the current process is long and complex, making it difficult for producers to giveaway the food in a timely manner.France’s f ood b anks a re o f c ourse t hrilled a bout t he p ossibility o f r eceiving e xtrafood. Jacques Bailet, who heads a network of French food banks called the Banques Alimentaires, says that of the 110,000 tons of goods received annually, only 36,000 tons comes from supermarkets. Bailet estimates (估计) that just a 15% increase insupermarket donations would translate to over 10 million additional meals to feed thehungry each year.Though this is a great first step, Arash Dermabarsh, the activist responsible forthe grassroots movement that led to the ban, is not done. He now wants to extend thelaw to other places like restaurants and also try to convince other countries in theEuropean Union to pass similar regulations. These steps are necessary because of theover 9 million tons of food wasted in France; an astonishing 67% is thrown away by consumers, with supermarkets and restaurants making up the rest.12.

Losing myself in painting filled me with peace. Painting provided me with the only place where I could escape from those threatening words.When I was twenty-one, my right eye went blind. Precisely three months after my twenty-fifth birthday, I had a massive hemorrhage (大出血) in my left eye because of an accident. For the next twenty years, vision came and went. I went through many eye operations in an attempt to keep my vision. But after one final operation, I lost the battle and all remaining vision. And I buried all dreams of painting.Desperate, I enrolled in (注册) a sixteen-week program for the blind and visually impaired (损伤的). I learned personal adjustment and the use of a computer with adaptive software. A whole new world opened up to me through this program.“Jaws and Window-Eyes are leading software for the blind,” my instructor told me. “You can use the Internet, e-mail and Microsoft with all its tools and features.” I t’s amazing! Hope went up for the first time in years. “By learning how to use hot keys to control the mouse, you can use Microsoft Access, Excel and Powerpoint,” my instructor added.For the next several years, I learned that when one door closes, another door opens. There are plenty of choicesavailable for the blind and visually impaired through the gift of technology. Not only do I have a speaking computer, but I have a speaking watch, alarm clock and calculator.4.What does the underlined word “it” in Paragraph 1 refer to?A. The right opportunity.B. Losing my sight in the future.C. Consuming too much sugarD. The children’s hospital.5. What happened when the author was 25 years old?A. He gave up painting.B. He went blind completelyC. He injured one of his eyes.D. He picked up a new hobby6. What brought a turning point to the author?A. A special course.B. A meaningful eventC. An inspiring speech.D. An important interview.7. What does the author intend to tell us?A. No pain, no gain.B. Every man has his price.C. Nothing is impossible to a willing heart.D. Be optimistic in the face of life’s difficulties.CThese days, I walk down the steps leading toward the south end of the All England Club in Wimbledon, and still look for the Crow’s Nest, a small green observation tower with an outer ladder that I used to climb on for a wide view of the grounds, but which has since been knocked down.The Crow’s Nest was a particularly useful point, because it allowed a tennis writer to keep trackof the action on as many as 10 outside courts at a time. At days end, reporters from different nations would share notes on what they had observed all over the grounds.Twenty-seven years later, the press room has touch screens that allow us to watch live videos from any court, and even go back to watch key moments in key matches long after they have finished. You could cover Wimbledon without leaving your seat. But that is a bit like spending all your time ordering room service and looking up fun facts on Wikipedia.More than at any other tennis tournament, there is also an appetite for stories that deal with the setting, the history and the traditions.If they change the price of the fish tacos (鱼肉卷饼) at the United States Open, it’s not a story. If they change the price of the strawberries and cream, the signature treat at Wimbledon. It’s time to email your editor using capital letters.The new retractable (可伸缩的) roof was put in place in 2009. Until then, you always had to have a rainy-daystory in your notebook because there were no guarantees any matches would be played. Now tennis is a sure thing on Centre Court, which has made tennis reporters a bit less creative. But at least it guarantees us daily access to the most atmospheric place in the sport.So much has changed, but Centre Court remains true to its original spirit: more a theater than a stadium. Catching that feeling is part of covering Wimbledon, too.8. What did the author do on the Cr ow’s Nest in the past?A. He made friends with reporters.B. He reported on tennis matches.C. He appreciated the beautiful scenery.D. He exchanged experiences with tennis players.9. What does the author think of the new way of covering Wimbledon?A. It lacks fun.B. It is expensiveC. It is not convenient.D. It is not quick enough10. Why does the author mention strawberries and cream?A. To compare popular foods.B. To introduce the typical treat at Wimbledon.C. To describe people’s craze f or traditional dishes.D. To show the traditions of Wimbledon are an attraction.11. What difference does the new roof make?A. Audiences have easier access to a tennis court.B. There’s less fun in watching Wimbledon indoors.C. Reporters are struggling to find original material.D. rainy-day stories about Wimbledon have become history.DOn January 13, 2016, France became the first country in the world to pass a law requiring supermarkets to donate food that is approaching its expiration date (保质期) instead of throwing it away. The regulation that applies to supermarkets over 4,000 square feet requires stores to sign official donation agreements with local food banks.The law also makes it illegal for stores to pour water over nearly-expired food, or store it inside locked warehouses until it is picked up by the garbage trucks. These measures are often undertaken by supermarkets to prevent the hungry from searching for food through the dustbins.Though that may appear cruel, the stores claim they do it to avoid potential food poisoning that could occur if the product is on its way past its expiry. Those who do not obey the new law face the risk of heavy fines.Also, excess goods like yogurt or milk that are likely to go bad quickly are now allowed to be donated directly to the food banks. Though this has always been possible, the current process is long and complex, making it difficult for producers to give away the food in a timely manner.France’s food banks are of course thrilled about the possib ility of receiving extra food. Jacques Bailet, who heads a network of French food banks called the Banques Alimentaires, says that of the 110,000 tons of goods received annually, only 36,000 tons comes from supermarkets. Bailet estimates (估计) that just a 15% increase in supermarket donations would translate to over 10 million additional meals to feed the hungry each year.Though this is a great first step, Arash Dermabarsh, the activist responsible for the grassroots movement that led to the ban, is not done. He now wants to extend the law to other places like restaurants and also try to convince other countries in the European Union to pass similar regulations. These steps are necessary because of the over 9 million tons of food wasted in France; an astonishing 67% is thrown away by consumers, with supermarkets and restaurants making up the rest.12. What should stores do with nearly-expired food?A. Throw it away.B. Send it to the hungry.C. Store it in refrigerators.D. Give it away to food banks.13. What does the underlined word “excess” in Paragraph 4 probably mean?A. Extra.B. Cheap.C. Seasonal.D. Returned.14. What might Bailet agree with about the French food banks?A. They have a lot of expired food.B. They will get much benefit from the law.C. Their food is enough for the people in need.D. Their food mainly comes from supermarkets.15. What does Dermabarsh plan to do?A. Build more food banks in France.B. Make the law take effect in more places.C. Organize a campaign to promote this law.D. Raise consumers awareness of waste reduction.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。

2019届广东省中山一中、仲元中学等七校高三第一次(8月)联考语文试卷现代文阅读1. 阅读下面的文字,完成小题。
百年中国美学的现代建构离不开对西方美学的借鉴,但这种借鉴乃是一个首先“学西”、继而“化西”的创造性现代转化的过程,某种意义上也是中西互鉴的特殊形态,从而达到中西美学不同程度的创新融合。
中国现代美学主要奠基人之一的王国维,早在20世纪初,在译介叔本华悲观主义意志论哲学著述基础上,撰写了迥异于传统思想的《红楼梦评论》;借鉴康德美学“鉴赏判断的四个契机”说,首次提出“一切之美,皆形式之美也”的重要主张,并建构起具有中国传统特质的“古雅”说;借鉴德国古典美学诸家,对中国古典美学尤其是先秦道家美学思想作了深刻反思,自觉把二者加以融会贯通,写出了《人间词话》这一中国现代美学的奠基之作,创建了以“境界”为核心范畴、意蕴丰厚的创新美学体系,对传统的“意境”说作出了具有现代性的创造性开拓。
王国维之所以在融通中西上作出如此巨大的贡献,与他具有超越中西学术二元对立的现代视野有密切关系。
他主张“学无中西”,批评持中学、西学二分的“俗说”,“虑西学之盛之妨中学,与虑中学之盛之妨西学者,均不根之说也”,认为“余谓中西二学,盛则俱盛,衰则俱衰,风气既开,互相推助。
且居今日之世,讲今日之学,未有西学不兴,而中学能兴者;亦未有中学不兴,而西学能兴者。
”这样一种关于中西学术互助、互动、互促、互鉴的精彩之论,至今仍不失其高远眼光和宏大气度。
另一位中国现代美学的主要奠基人蔡元培,在国内最早全面介绍了康德的美学思想,对康德关于审美四契机说,运用儒家思想作了“超脱”“普遍”“有则”“必然”的创造性阐述;从儒家以德为本的思想出发,借鉴康德有关思想并加以吸收融化,同时借鉴席勒的美育理论,强调“涵养德性,则莫若提倡美育”,进而提出了中国现代美学史上具有里程碑意义的“美育代宗教”说。
还有梁启超,前期以启蒙为宗旨,强调文艺改造人心的社会功能,提出了诗、文、小说的三界革命论,目的在“新民立人”或曰“移人”;后来借鉴西方哲学智、情、意三分理论,用儒家思想加以化用,提出以“情感教育”“趣味教育”为中心、以文学艺术为主要内容和形式的“趣味主义”美学主张,在上世纪20年代产生了广泛影响。

七校联合体2019届高三第一次联考试卷(8月)理科综合物理二、选择题:1. 质点做直线运动的速度—时间图象如图所示,该质点().........A. 在第1秒末速度方向发生了改变B. 在第2秒末加速度方向发生了改变C. 第1秒末和第3秒末的位置相同D. 在前6秒内发生的位移为零【答案】C【解析】【详解】0-2s内速度图象在时间轴的上方,都为正,在第1秒末速度方向没有改变。
故A错误;速度时间图象的斜率表示加速度,由图可知1-3s图象斜率不变,加速度不变,方向没有发生改变,故B错误;根据“面积”表示位移可知,前1s内的位移x1=×2×1=1m,前3秒内发生的位移为x=×2×2-×2×1=1m,故两段时间内的位移相同,故第1s末和第3s末的位置相同,故C正确;由图像可知,t=4s内的位移为零,则在前6秒内发生的位移等于4-6s的位移,不为零,故D错误。
故选C。
【点睛】本题考查v-t图象的性质的掌握和应用,要注意深刻理解某一段时间内的位移就等于在该段时间内速度图象与时间轴围成的面积是解决此类题目的突破口.2. 我国女子短道速滑队在2013年世锦赛上实现女子3000m接力三连冠。
观察发现,“接棒”的运动员甲提前站在“交棒”的运动员乙前面,并且开始向前滑行,待乙追上甲时,乙猛推甲一把,使甲获得更大的速度向前冲出。
在乙推甲的过程中,忽略运动员与冰面间在水平方向上的相互作用,则()A. 甲对乙的冲量一定等于乙对甲的冲量B. 甲、乙的动量变化一定大小相等方向相反C. 甲的动能增加量一定等于乙的动能减少量D. 甲对乙做多少负功,乙对甲就一定做多少正功【答案】B【解析】【详解】甲对乙的冲量与乙对甲的冲量大小相等、方向相反,故A错误;二人相互作用的过程中动量守恒,根据动量守恒可知,甲、乙的动量变化一定大小相等方向相反,故B正确;甲、乙间的作用力大小相等,不知道甲、乙的质量关系,不能求出甲乙动能变化关系,无法判断做功多少,也不能判断出二者动能的变化量,故CD错误;故选B。
