While some people have tried going cold turkey(快速戒掉坏习惯) or even punishing themselves for their mobile phones, an app is made available in the UK that rewards people for staying away from their devices.The app, called Hold, was created by Norwegians Maths Mathisen, Florian Winder, and VinothVinaya while they are studying at Copenhagen's Business school, to help break fellow students' attachments to their devices.The three college students found that positive reinforcement(强化)was the best way of beating smartphone addiction. Hold allows students to collect points for staying off their devices between the hours of 7 am and 11 pm; they get 10 points for every 20 minutes.Through partnerships with universities and businesses, points can be used for discounts on everything from cinema tickets to Amazon goods to cafe food and drink. A half price cinema ticket, for example, costs 60 points, or 2 hours away from a phone. And a￡5($ 6.88)Amazon voucher (代金券) needs 1,000 points, or 33 hours off your smartphone.Students can also use their points to buy school books and stationery(文具), which are then donated to schools partnered with children's charity Unicef.Over 120, 000 people use the app in Scandinavia, including 40 percent of higher education students in Norway, where Hold first came onto market in February 2016. It's now available to students from over 170 universities in the UK.A 2017 University of Texas study claimed that merely placing a smartphone in someone's line of sight slowed down their productivity, response time, and reduced their grades. An earlier study from the London School of Economics found students who didn't use smartphones on school grounds saw their test scores increase 6. 4 percent.24. The app Hold was created mainly to .A. promote online sales of goodsB. earn discounts on goods or servicesC. find new uses of mobile phonesD. help students put down their smartphones25. How long should a student stay off the mobile phone to get 300 points?A. 6 hours.B. 10 hours.C. 15 hours.D. 30 hours.26. What is the main purpose of the text?A. To tell the story of Hold creationB. To present people's opinions of HoldC. To give a brief introduction of HoldD. To attract potential customers to Hold27. Where is the text most likely to appear?A. A newspaper advertisementB. A computer textbookC. A science magazineD. An official documentCThe dancer put a cardigan sweater over her leotard. Then she sat down to eat a sandwich. Cardigan, leotard, sandwich-where did these words come from? Did you know that each of them was a person's name? Words that come from proper names are called eponyms(名祖名词), and there are many eponyms in English.The sandwich, for example, was named for John Montagu, the Earl(伯爵)of Sandwich. He lived from 1718-1792. He loved to play cards and did not want to stop a game even to eat. By putting cold meat between two pieces of bread, he could eat while he played.The cardigan sweater was named for an officer in the British army. In the 1800s, James Thomas Brudenell, the Earl of Cardigan, spent his own money to buy special knitted(针织的)jackets for the men in his army. Knitted jackets with buttons soon came to be called cardigans.Jules Leotard was a French circus performer. In 1859, at the age of twenty-one, Leotard performed the first mid-air somersault(空翻). He became known as the "daring young man on the flying trapeze(吊杠)". Leotard invented a close-fitting one-piece suit to wear when he performed. Dancers still call their close-fitting garments leotards.Another person who gave her name to a style of clothing was Amelia Bloomer. Bloomer was the editor of a magazine called The Lily. American women in her day were expected to wear heavy skirts that dragged on the floor. In 1851, a young woman named Elizabeth Smith Miller introduced a new kind of clothing that was much easier to move around in. She wore a dress that came only to the knees. Under it she wore loose pants that fitted close at the ankles. Amelia Bloomer published a picture of the outfit(全套服装)in the Lily.She hoped women would adopt the new style. In news stories, reporters called the pants "bloomers". A hundred years later, people were still using the word.There are many other words that come from people's names. The diesel engine was named for its inventor, Rudolf Diesel. The word boycott comes from the name of an English landlord named Charles Boycott. Where each word came from is a story in itself. Who knows, maybe your name will become a word someday.28. Why did the Earl of Sandwich invent the "sandwich"?A. He found it boring to play cards.B. He preferred to eat meat and bread.C. He wanted to create a new kind of food.D. He could eat while playing cards without stopping the game.29. According to the text, what do "bloomers" refer to?A. Loose dressesB. Loose pants worn under a dressC. Dresses that came to the kneesD. Heavy skirts dragged on the floor30. What do the words cardigan, leotard and sandwich have in common?A. They are still in use today.B. They were first used in the army.C. They belong to the clothing category.D. They were invented during the same period.31. What is the best title for this passage?A. Ways to remember words.B. Words that come from people's names.C. The history of garments development.D. The unknown stories behind English words.DA team of researchers led by engineers from Penn State University has created the first material that heals itself in the presence of water, according to a study published in Scientific Reports. The material, inspired by squid(鱿鱼)teeth, could be used to repair instruments in water-filled environments that are difficult to access, such as the human body, or the bottom of the sea.The researchers had been studying squids' ring teeth, which are uniquely strong and can change state from liquid to solid in the presence of water. After testing ring teeth samples from several species of squid found all over the world, the researchers uncovered the genetic code for the proteins (蛋白质) that allow the teeth to heal themselves when broken. They then changed the genetic structure of bacteria to produce the proteins so they could conduct more tests.The researchers then made the proteins into a rubbery plastic by mixing them with a solvent(溶剂)and letting the solvent change into a gas. The resulting material combines a soft, shapeless part of the protein that gives the plastic its self-healing characteristics and a more structured sheet of amino acids(氨基酸)that give it a solid structure.To test the material's strength, the researchers cut it, and then put the two pieces back together with a drop of water. They found that the material healed best at 113 degrees Fahrenheit, a little warmer than the temperature of the human body, and with slight pressure from a metal tool. The material was just as strong, and able to hold the same amount of weight, before and after it was cut.Material that heals itself in the presence of water could expand the usability of biomedical implants(移植). Of course, this material is nowhere near ready for that application, and the researchers didn't test whether the constant presence of water degrades(降低)the plastic's ability to heal itself. The researchers next plan to study how their technology could help heal wounds.32. According to paragraph 3, the rubbery plastic become self-healing in combination with .A. amino acidsB. another kind of rubberC. a mixture of gasesD. some protein33. In paragraph 4, the researchers carried out a test to check whether the material .A. was fit for human bodyB. would melt at high temperaturesC. could be connected with the metalD. would recover its original strength after healing itself34. What is the author's attitude towards the self-healing material?A. Positive.B. Objective.C. Doubtful.D. Critical.35. What is the main idea of the text?A. A kind of self-healing teeth was made from squids' ring teeth.B. The genetic code of squids' special teeth has been uncovered.C. Super-strong material inspired by squid teeth is self-healing.D. A special rubbery plastic is used to replace squids' teeth.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。

He lived from 1718-1792. He loved to play cards and did not want to stop a game even to eat. By putting cold meat between two pieces of bread, he could eat while he played.The cardigan sweater was named for an officer in the British army. In the 1800s, James Thomas Brudenell, the Earl of Cardigan, spent his own money to buy special knitted(针织的)jackets for the men in his army. Knitted jackets with buttons soon came to be called cardigans.Jules Leotard was a French circus performer. In 1859, at the age of twenty-one, Leotard performed the first mid-air somersault(空翻). He became known as the "daring young man on the flying trapeze(吊杠)". Leotard invented a close-fitting one-piece suit to wear when he performed. Dancers still call their close-fitting garments leotards.Another person who gave her name to a style of clothing was Amelia Bloomer. Bloomer was the editor of a magazine called The Lily. American women in her day were expected to wear heavy skirts that dragged on the floor. In 1851, a young woman named Elizabeth Smith Miller introduced a new kind of clothing that was much easier to move around in. She wore a dress that came only to the knees. Under it she wore loose pants that fitted close at the ankles. Amelia Bloomer published a picture of the outfit(全套服装)in the Lily. She hoped women would adopt the new style. In news stories, reporters called the pants "bloomers". A hundred years later, people were still using the word.There are many other words that come from people's names. The diesel engine was named for its inventor, Rudolf Diesel. The word boycott comes from the name of an English landlord named Charles Boycott. Where each word came from is a story in itself. Who knows, maybe your name will become a word someday.28. Why did the Earl of Sandwich invent the "sandwich"?A. He found it boring to play cards.B. He preferred to eat meat and bread.C. He wanted to create a new kind of food.D. He could eat while playing cards without stopping the game.29. According to the text, what do "bloomers" refer to?A. Loose dressesB. Loose pants worn under a dressC. Dresses that came to the kneesD. Heavy skirts dragged on the floor30. What do the words cardigan, leotard and sandwich have in common?A. They are still in use today.B. They were first used in the army.C. They belong to the clothing category.D. They were invented during the same period.31. What is the best title for this passage?A. Ways to remember words.B. Words that come from people's names.C. The history of garments development.D. The unknown stories behind English words.DA team of researchers led by engineers from Penn State University has created the first material that heals itself in the presence of water, according to a study published in Scientific Reports. The material, inspired by squid(鱿鱼)teeth, could be used to repair instruments in water-filled environments that are difficult to access, such as the human body, or the bottom of the sea.The researchers had been studying squids' ring teeth, which are uniquely strong and can change state from liquid to solid in the presence of water. After testing ring teeth samples from several species of squid found all over the world, the researchers uncovered the genetic code for the proteins (蛋白质) that allow the teeth to heal themselves when broken. They then changed the genetic structure of bacteria to produce the proteins so they could conduct more tests.The researchers then made the proteins into a rubbery plastic by mixing them with a solvent(溶剂)and letting the solvent change into a gas. The resulting material combines a soft, shapeless part of the protein that gives the plastic its self-healing characteristics and a more structured sheet of amino acids(氨基酸)that give it a solid structure.To test the material's strength, the researchers cut it, and then put the two pieces back together with a drop of water. They found that the material healed best at 113 degrees Fahrenheit, a little warmer than the temperature of the human body, and with slight pressure from a metal tool. The material was just as strong, and able to hold the same amount of weight, before and after it was cut.Material that heals itself in the presence of water could expand the usability of biomedical implants(移植). Of course, this material is nowhere near ready for that application, and the researchers didn't test whether the constant presence of water degrades(降低)the plastic's ability to heal itself. The researchers next plan to study how their technology could help heal wounds.32. According to paragraph 3, the rubbery plastic become self-healing in combination with .A. amino acidsB. another kind of rubberC. a mixture of gasesD. some protein33. In paragraph 4, the researchers carried out a test to check whether the material .A. was fit for human bodyB. would melt at high temperaturesC. could be connected with the metalD. would recover its original strength after healing itself34. What is the author's attitude towards the self-healing material?A. Positive.B. Objective.C. Doubtful.D. Critical.35. What is the main idea of the text?A. A kind of self-healing teeth was made from squids' ring teeth.B. The genetic code of squids' special teeth has been uncovered.C. Super-strong material inspired by squid teeth is self-healing.D. A special rubbery plastic is used to replace squids' teeth.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。

河南省豫南九校2020-2021学年高二上学期第二次联考语文试题(wd无答案)
河南省豫南九校2020-2021学年高二上学期第二次联考语文试题一、现代文阅读(★★★) 1. 阅读下面的文字，完成各题。
在中国历史上，被中央政府认定并封为圣人、居文庙与学校（庙学合一）之上而享受“国之典祀”的，只有五人：至圣孔子、复圣颜子、宗圣曾子、述圣子思子、亚圣孟子。
儒家这几位圣人有一项重要的贡献，那就是他们对尧舜以来优良家学、家教、家风的传承、弘扬与创新发展，形成了圣人家风。
孔子、颜子、曾子、孟子拥有最优秀的家教。
他们的家教，一半出自母教：孔子、孟子自幼丧父，靠母亲抚养、教育成人。
孔母、孟母是母教的典范。
这两位伟大的母亲先后独自承担起家教的重任，上承邹鲁家教优良传统，下启邹鲁孔、颜、曾、孟四氏家风，其母仅千古的风范令人赞叹不已。
孔子、孟子仰承母教而成长。
待到他们成家生子以后，必对慈母的家教有着强烈、深刻、鲜活的记忆，必将慈母的家教发扬光大于门庭之内，再结合他们的家教理念而予以创新发展，这就形成了孔孟二氏家风。
颜子、曾子因为父亲健在长寿，不走孔盂家风形成之路；他们二人情况类似，都是父子同入孔门学习，直接受孔子的教诲和影响而形成各自的家风。
颜子、曾子是一代更比一代强的后起之秀，他们对于各自家风的贡献自然更大一些。
孔子、颜子、曾子、孟子培育的家风，可以称为圣人家风。
但是，圣人家风不以富与贵的家境为基础，不是高不可攀，而是来自于普通的家庭。
孔子、孟子出身于单亲家庭，孤儿寡母，虽然生活困苦，但拥有了良好的母教和家风，也有机会“下学而上迭”，出类拔萃，成为优畀人才。
待到孔子、孟子成贤成圣，光大门楣，他们的家风就直接转换成了圣人家风。
孔、颜、曾、孟四氏圣人家风，由家学、家教而形成，极高明而道中庸，具有领先性和示范性的特点。
就其极高明而言，孔子、颜子、曾子、孟子奠定的家风，形成了家学、家教、家风的完整序列，家风以家教为基础，家教以家学为根底，成为后世孔、颜、曾、孟四氏后裔以及历朝历代名门望族效法的家风范式。
