AInside the Rain RoomThe Rain Room has arrived and local art lovers are taking notice. Is it worth the wait? Yes, I assure you it is. Once inside, visitors find a long, dark room with a high ceiling. A single bright light shines through heavy rain falling around visitors. The mist. The damp air. The noise. It feels like a mighty storm is pouring down. But the storm is inside. And visitors aren’t getting wet. Instead, visitors wander in awe, admiring the rain and the artists who created it.The Rain Room was created to highlight the connection between humans, nature and technology. With a tracking system that senses movement and stops the rain wherever visitors move, it does just that. Light and sound produce an experience that feels both natural and foreign. The exhibit is moving on to Atlanta next month. I urge you to visit before then. It’s time to experience the Rain Room for yourself!21. What’s the purpose of the text?A. To attract visitors to a new art exhibit.B. To explain how an exhibit has been created.C. To describe the technology used in the exhibitD. To promote the artists taking part in an exhibit.22. What’s the function of the exhibit’s tracking system?A. To keep visitors from getting wet.B. To protect the exhibit from water damage.C. To time how long visitors are in the room.D. To count the number of visitors in the room.23. What must you do when visiting the Rain Room?A. Wear a raincoat.B. Wear dark clothing.C. Leave your camera outsideD. Pass through within 10 minutesBDujiangyan is the oldest man-made water system in the world, and a wonder in the development of Chinese science. Built over 2,200 years ago in what is now Sichuan Province in Southwest China, this amazing engineering achievement is still used today to irrigate over 6,000 square kilometres of farmland, take away floodwater and provide water for 50 cities in the province.In ancient times, the region in which Dujiangyan now stands suffered from regular floods caused by overflow from the Minjiang River. To help the victims of the flooding, Li Bing, the region’s governor, together with his son, decided to find a solution. They studied the problem and discovered that the river most often overflowed when winter snow at the top of the nearby Mount Yulei began to melt as the weather warmed.The simplest fix was to build a dam, but this would have mined the Minjiang River. So instead Li designed a series of channels built at different levels along Mount Yulei that would take away the floodwater while leaving the river flowing naturally. Better still, the extra water could be directed to the dry Chengdu Plain, making it suitable for farming.Cutting the channels through the hard rock of Mount Yulei was a remarkable accomplish- ment as it was done long before the invention of gunpowder and explosives. Li Bing found another solution. He used a combination of fire and water to heat and cool the rocks until they cracked and could be removed. After eight years of work, the 2-metre-wide canals had been carved through the mountain.Once the system was finished, no more floods occurred and the people were able to live peacefully and affluently. Today, Dujiangyan is admired by scientists from around the world because of one feature. Unlike modern dams where the water is blocked with a huge wall, Dujiangyan still lets water flow through the Minjiang River naturally, enabling ecosystems and fish populations to exist in harmony.24. What are the benefits of Dujiangyan according to the first paragraph?A. Reducing flooding and watering farmland.B. Protecting the mountain and reducing flooding.C. Watering farmland and improving water quality.D. Drying the river and supplying cities with water.25. What was the main cause of the Minjiang River’s flooding?A. Heavy rains.B. Melting snow.C. Low river banks.D. Steep mountains.26. How was Li Bing able to break。

第I卷阅读题一、现代文阅读(35分)(一)论述类文本阅读(9分,每小题3分)阅读下面的文字,完成1一3题。
儒家之心学是全部儒学思想最基本的“硬核”,其他方面都是心学的延伸和展开。
王阳明说“君子之学,谁求得其心”,心学就是强调主体自我的儒学,突出自信、自强、自律、自为,追求自我实现。
“心学”的本质就是追求“内圣外王”价值取向,并为其寻求理论根据和修养方法的哲学。
心学发端于春秋战国时期的孔子和孟子。
孔子率先发现了人的自我,创立了以“仁学”“礼学”为核心的原始儒学,提出了“心安”的心性问题。
孟子继承发展了孔子学说,比孔子更为突出地把心性之体表露出来,最先注意到心的作用。
孟子认为:孔子所谓“仁”归根结底是人之心,“仁,人心也”(《孟子·告子上》);“性”根源于“心”,“君子所性,仁义礼智根于心”(《孟子·告子上》);只要尽心便能知性,“尽其心者,知其性也;知其性,则知天矣”(《孟子·告子上》)。
由此,孟子确立了儒家心性之学的基本理念。
儒家心性论的最初建构者是思孟学派,传承谱系是:由孔子到曾参,由曾参到子思,由子思到孟子。
其学术传承:孔子有《论语》,曾参有《大学》,子思有《中庸》,孟子有《孟子》。
心学到了宋代,由北宋程颐开其端,南宋陆九渊大启其门径:清初的李二曲把陆九渊比作接续孟氏之后的第一人。
“议论削爽,令人当下心豁目明;简易直捷,孟氏之后仅见”。
陆九渊不仅“发明”出“本心”,更重要的是他对此作了大致轮廓的描述:“心之体甚大。
若能尽我之心,便与天同。
”“此理塞宇宙”。
宋代理学各学派都细致入微地谈论心性问题,有“无事袖手谈心性”之说,心性之学成为理学的代名词。
明代中叶,心学集大成者王阳明首度提出“心学”二字,王阳明序《象山先生全集》曰:“圣人之学,心学也。

AInside the Rain RoomThe Rain Room has arrived and local art lovers are taking notice. Is it worth the wait? Yes, I assure you it is. Once inside, visitors find a long, dark room with a high ceiling. A single bright light shines through heavy rain falling around visitors. The mist. The damp air. The noise. It feels like a mighty storm is pouring down. But the storm is inside. And visitors aren’t getting wet. Instead, visitors wander in awe, admiring the rain and the artists who created it.The Rain Room was created to highlight the connection between humans, nature and technology. With a tracking system that senses movement and stops the rain wherever visitors move, it does just that. Light and sound produce an experience that feels both natural and foreign. The exhibit is moving on to Atlanta next month. I urge you to visit before then. It’s time to experience the Rain Room for yourself!Welcome to the Rain Room●The Rain Room features falling water. Please be aware you may get slightly wet.However, visitors wearing raincoats will be turned away.●This exhibit features advanced technology. To ensure its effectiveness, please avoidwearing dark or reflective clothing.●Visitors are welcome to take photographs of the exhibit.●Children must be accompanied by an adult.●For the convenience of all guests, visits are limited to 10 minutes.21. What's the purpose of the text?A. To attract visitors to a new art exhibit.B. To explain how an exhibit has been created.C. To describe the technology used in the exhibit.D. To promote the artists taking part in an exhibit.22. What’s the function of the exhibit’s tracking system?A. To keep visitors from getting wet.B. To protect the exhibit from water damage.C. To time how long visitors are in the room.D. To count the number of visitors in the room.23. What must you do when visiting the Rain Room?A. Wear a raincoat.B. Wear dark clothing.C. Leave your camera outside.D. Pass through within 10 minutes.BDujiangyan is the oldest man-made water system in the world, and a wonder in the development of Chinese science. Built over 2, 200 years ago in what is now Sichuan Province in Southwest China, this amazing engineering achievement is still used today to irrigate over 6, 000 square kilometres of farmland, take away floodwater and provide water for 50 cities in the province.In ancient times, the region in which Dujiangyan now stands suffered from regular floods caused by overflow from the Minjiang River. To help the victims of the flooding, Li Bing, the region’s governor, together with his son, decided to find a solution. They studied the problem and discovered that the river most often overflowed when winter snow at the top of the nearby Mount Yulei began to melt as the weather warmed.The simplest fix was to build a dam, but this would have ruined the Minjiang River. So instead Li designed a series of channels built at different levels along Mount Yulei that would take away the floodwater while leaving the river flowing naturally. Better still, the extra water could be directed to the dry Chengdu Plain, making it suitable for farming.Cutting the channels through the hard rock of Mount Yulei was a remarkable accomplishment as it was done long before the invention of gunpowder and explosives. Li Bing found another solution. He used a combination of fire and water to heat and cool the rocks until they cracked and could be removed. After eight years of work, the 20-metre-wide canals had been carved through the mountain.Once the system was finished, no more floods occurred and the people were able to live peacefully and affluently. Today, Dujiangyan is admired by scientists from around the world because of one feature. Unlike modern dams where the water is blocked with a huge wall, Dujiangyan still lets water flow through the Minjiang River naturally, enabling ecosystems and fish populations to exist in harmony.24. What are the benefits of Dujiangyan according to the first paragraph?A. Reducing flooding and watering farmland.B. Protecting the mountain and reducing the flooding.C. Watering farmland and improving water quality.D. Drying the river and supplying cities with water.25. What was the main cause of the Minjiang River’s flooding?A. Heaving rainsB. Melting snow.C. Low river banksC. Steep mountains.26. How was Li Bing able to break through the rocks of Mount Yulei?A. By using gunpowder.B. By flooding the rocks with water.C. By applying a hearing and cooling technique.D. By breaking the rocks with hammers and spades27. Why is Dujiangyan greatly admired by scientists today?A. It preserved much of the natural river life.B. It took very little time to complete the project.C. The building techniques used were very modern.D. It had raised the living standards of the local people.CBill Gates recently predicted that online learning will make place-based colleges less significant, and five years from now, students will be able to find the best lectures in the world online. I applaud Mr. Gates. But what’s taking us so long?As early as 1997, MIT(麻省理工)decide to post videos of all university lectures online, for free, for all people. But today, how many students have you met who mastered advanced mathematics or nuclear physics from an MIT online video? Unfortunately, the answer is not many.The problem is the poor quality of online education websites and the experience they provide to students. Those who go to the MIT website and watch courses online are surely very smart people, but it’s not like playing a video game such as World of Warcraft. Only the most ardent students, those who are highly motivated, will devote themselves tostudying these boring online videos.The real question is why er aren’t spending more to develop better online education platforms. Where is the Avatar of education? Think about this. The market for Hollywood films per year is worth around 30 billion USD. Education in the world is a trillion-dollar-a-year market, hundreds of times bigger than Hollywood movies. Yet the most expensive digital learning system ever built cost well under 100 million dollars.Bill Gates’ prediction is going to happen. There is no doubt about this. But it will only happen when we create high level educational content and experiences that engage and excite more than has ever been possible in the real world.28. What has Bill Gates forecast about online learning?A. It will concentrate on physics lectures.B. It will completely replace real universities.C. It will help to make universities more successful.D. It will play an increasingly important role in education.29. What does the underlined word “ardent” in Paragraph 3 mean?A. Creative.B. Enthusiastic.C. Well-behaved.D. Experienced.30. According to the author, what is holding back the popularity of online learning?A. The lack of lectures available online.B. The high cost of access to the websites.C. The low standard of educational websites.D. The competition with online computer games.31. Why does the author mention Hollywood?A. To show that Hollywood produces many successful movies.B. To prove that education is more profitable than entertainment.C. To argue that movie directors should produce educational content.D. To urge that more money be spent developing educational websites.DPersuasion is the art of convincing someone to agree with you. According to the ancient Greeks, there are three basic tools of persuasion: ethos, pathos, and logos.Ethos is a speaker’s way of convincing the audience that she is trustworthy, honest and reliable. One common way a speaker can develop ethos is by explaining how much experience or education she has in the field. After all, you’re more likey to listen to advice about how to take care of your teeth from a dentist than a fireman. A speaker can also create ethos by convincing the audience that she is a good person. If an audience cannot trust you, you will not be able to persuade them.Pathos is a speaker’s way of connecting with an audience’s emotions. For example, a politician who is trying to convince an audience to vote for him might say that he alone can save the country from a terrible war. These words are intended to fill the audience with fear, thus making them support him. Similarly, an animal charity might show an audience pictures of injured dos and cats, to make the viewers feel pity. If the audience feels bad forthe animals, they ill be more likely to donate money.Logos is the use of facts, statistics, or other evidence to support your argument. An audience will be more likely to believe you if you have convincing data to back up your claims. Presenting this evidence is much more persuasive than simply saying “believe me”.Although ethos, pathos, and logos all have their strengths, they are often most effective when used together. Indeed, most speakers use a combination of ethos, pathos, and logs to persuade their audiences so, the next time you listen to a speech, watch a commercial, or listen to a friend try to convince you to lend him some money, be on the lookout for these ancient Greek tools of persuasion.32. Why does the author say persuasion is an art?A. They both entertain the audience.B. They both require great skill to achieve.C. They both demand full attention from the audience.D. They were both common topics of ancient Greek writers.33. How is a speaker able to show her ethos to the audience?A. By expressing her sympathy with the audience.B. By telling the audience about her personal preference.C. By using beautiful language to make her statements attractive.D. By showing her knowledge and experience relating to the topic..34. What can we learn about the three aspects of persuasion?A. Ethos is the most important aspect of persuasion.B. Each aspect has a different effect on the audience.C. Honesty is the key to making your arguments believable.D. Political leaders mostly use pathos to persuade their audience.35. An advertisement for washing powder which claims that “scientific tests show that our powder kills 95% of all bacteria: is mainly using _____________.A. ethosB. pathosC. logosD. A combination of all three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。

智能时代,更要力求创新 李卓(下水作文?)
放眼当下市场,手机品牌林立,手机换代加速。面 对日益激烈的竞争,甲乙丙三家企业却能独立潮头,矢 志创新,其姿态与做法尤其值得称赏。 • 三家企业用实际行动告诉我们:创新在于精益求精, 创新之路永无止境。世上没有一蹴而就的创新,创新需 要不断钻研;世上更没有一劳永逸的创新,创新不可能 永远都“新”。实际上,任何事物的发展都是“新”与 “旧”更迭相继的过程。古语云:“苟日新,日日新, 又日新”,就是强调创新是一个动态发展的过程,而不 是一个结果。当下的手机已经普遍具备了极好的芯片、 机身、摄像头了,但甲企业仍在这方面力求更好。乙、 丙企业也在各自的领域力求更好。当年的诺基亚手机性 能出众,但其创新意识不足,结果在手机智能化的潮流 中失去了市场。反观苹果手机,不断换代更新,追求更 佳的性能、更好的操作体验,成为世界手机市场上的霸 主。可见,创新没有最好,只有更好。
2017广州一模语文试卷及答案解析
2017届广州市普通高中毕业班综合测试(一)语文本试卷10页,22小题,满分150分。
考试时间150分钟。
第I卷阅读题一、现代文阅读(35分)(一)论述类文本阅读(9分,每小题3分)阅读下面的文字,完成1一3题。
儒家之心学是全部儒学思想最基本的“硬核”,其他方面都是心学的延伸和展开。
王阳明说“君子之学,谁求得其心”,心学就是强调主体自我的儒学,突出自信、自强、自律、自为,追求自我实现。
“心学”的本质就是追求“内圣外王”价值取向,并为其寻求理论根据和修养方法的哲学。
心学发端于春秋战国时期的孔子和孟子。
孔子率先发现了人的自我,创立了以“仁学”“礼学”为核心的原始儒学,提出了“心安”的心性问题。
孟子继承发展了孔子学说,比孔子更为突出地把心性之体表露出来,最先注意到心的作用。
孟子认为:孔子所谓“仁”归根结底是人之心,“仁,人心也”(《孟子·告子上》);“性”根源于“心”,“君子所性,仁义礼智根于心”(《孟子·告子上》);只要尽心便能知性,“尽其心者,知其性也;知其性,则知天矣”(《孟子·告子上》)。
由此,孟子确立了儒家心性之学的基本理念。
儒家心性论的最初建构者是思孟学派,传承谱系是:由孔子到曾参,由曾参到子思,由子思到孟子。
其学术传承:孔子有《论语》,曾参有《大学》,子思有《中庸》,孟子有《孟子》。
心学到了宋代,由北宋程颐开其端,南宋陆九渊大启其门径:清初的李二曲把陆九渊比作接续孟氏之后的第一人。
“议论削爽,令人当下心豁目明;简易直捷,孟氏之后仅见”。
陆九渊不仅“发明”出“本心”,更重要的是他对此作了大致轮廓的描述:“心之体甚大。
若能尽我之心,便与天同。
”“此理塞宇宙”。
宋代理学各学派都细致入微地谈论心性问题,有“无事袖手谈心性”之说,心性之学成为理学的代名词。
明代中叶,心学集大成者王阳明首度提出“心学”二字,王阳明序《象山先生全集》曰:“圣人之学,心学也。
”阳明心学的经典表述,即著名的四句教:“无善无恶心之体,有善有恶意之动,知善知恶是良知,为善去恶是格物。

I applaud Mr. Gates. But what’s taking us so long?As early as 1997, MIT (麻省理工)decided to post videos of all university lectures online, for free, for all people. But today, how many students have you met who mastered advanced mathematics or nuclear physics from an MIT online video? Unfortunately, the answer is not many.The problem is the poor quality of online education websites and the experience they provide to students. Those who go to the MIT website and watch courses online are surely very smart people, but ifs not like playing a video game such as World of Warcraft. Only the most ardent students, those who are highly motivated, will devote themselves to studying these boring online videos.The real question is why we aren’t spending more to develop better online education platforms. Where is the Avatar of education? Think about this. The market for Hollywood films per year is worth around 30 billion USD. Education in the world is a trillion-dollar-a-year market, hundreds of times bigger than Hollywood movies. Yet the most expensive digital learning system ever built cost well under 100 million dollars.Bill Gates’ prediction is going to happen. There is no doubt about it.

According to the ancient Greeks, there are three basic tools of persuasion : ethos, pathos, and logos.Ethos is a speakers way of convincing the audience that she is trustworthy, honest and reliable. One common way a speaker can develop ethos is by explaining how much experience or education she has in the field. After all, you’re more likely to listen to advice about how to take care of your teeth from a dentist than a fireman. A speaker can also create ethos by convincing the audience that she is a good person. If an audience cannot trust you, you will not be able to persuade them.Pathos is a speaker’s way of connecting with an audience’s emotions. For example, a politician who is trying to convince an audience to vote for him might say that he alone can save the country from a terrible war. These words are intended to fill the audience with fear, thus making them support him. Similarly, an animal charity might show an audience pictures of injured dogs and cats, to make the viewers feel pity. If the audience feels bad for the animals, they will be more likely to donate money.Logos is the use of facts, statistics, or other evidence to support your argument. An audience will be more likely to believe you if you have convincing data to back up your claims. Presenting this evidence is much more persuasive than simply saying “believe me”.Although ethos, pathos, and logos all have their strengths, they are often most effective whenused together. Indeed, most speakers use a combination of ethos, pathos, and logos to persuade their audiences. So, the next time you listen to a speech, watch a commercial, or listen to a friend try to convince you to lend him some money, be on the lookout for these ancient Greek tools of persuasion.32.

By telling the audience about her personal preference.C. By using beautiful language to make her statements attractive.D. By showing her knowledge and experience relating to the topic. .34. What can we learn about the three aspects of persuasion?A. Ethos is the most important aspect of persuasion.B. Each aspect has a different effect on the audience.C. Honesty is the key to making your arguments believable.D. Political leaders mostly use pathos to persuade their audience.35.
