N.Ambassador Koro Bessho."It caused severe damage.We had dams；we had drills.However,we had been counting on something that hits every100years and the earthquake was of the size of possibly every500 years or thousand years,he said.These two events sent the countries of the region into overdrive to review and improve disaster preparedness.In2015the Sendai Framework for Disaster Risk Reduction was born.It aims to help create a better understanding of disaster risk and improve preparedness for an effective response.Indonesia is made up of thousands of islands which are disaster-prone（易受灾地区）.Willem Rampangilei,head of the Disaster Management Agency of Indonesia,said his government now has plans for every disaster-prone city.Countries at risk are also expanding their education programs.Children from an early age are taught how to react in case of a tsunami and then go with their classmates to higher ground away from coastal areas to avoid the walls of water the tsunami triggers.24.What does Georgi Velikov Panayotov mainly talk about?A.The general features of a tsunami.B.Ways for humans to face a tsunami.C.His suffering in the2004tsunami.D.The loss caused by the2004tsunami.25.In Koro Bessho's opinion,why did the2011earthquake cause severe damage?A.It caused a fierce tsunami.B.It destroyed a nuclear plant.C.The size was beyond expectation.D.There was no effective defense system.26.What common belief pushed different countries to take action to face a coming tsunami?A.Children should be protected by all means.B.The improvement of preparedness can reduce damage.C.Proper response in case of a tsunami can save one's life.D.Stronger measures should be taken in disaster-prone areas.27.Which can be the best title of the text?A.World Tsunami Awareness DayB.Nations Attacked by Massive TsunamiC.The Unpredictable and Destructive DisasterD.Learn from Disasters to Prevent Future OnesCArcheology（考古学）isn't the dusty science it was a generation ago.New technologies that once seemed out of sci-fi are now locating buried traces of buildings and revealing the ruins of cities.For more than a decade,Sarah Parcak and her team have been on the front line of this revolution.They use satellite images to find and explore ancient sites around the globe.Now they're about to take on a new challenge as they focus Global Xplorer citizen-science project on India.In2017,Parcak launched an online platform,called Global Xplorer,to crowd source（群众外包）the initial assessment of satellite images for signs of cultures from long ago.Anyone in the world with a computer and Internet access could help discover and protect remains of Peru's rich cultural heritage.The results have been surprising.About80,000participants from a hundred countries have identified19,000sites that were not in Peru's database.The platform for Peru is still running.If all goes well,the work in India could last for years."India has had relatively little archaeological work done,"Parcak says.Also,the full extent of India's archaeological work has never been mapped completely. Parcak expects her project to make up that.“Wherever we end up going,the crowd's going to be able to see extraordinary things,"Parcak says.Thirty six India's cultural heritage relics are already listed as UNESCO World Heritage Sites.Parcak thinks there could be tens of thousands of as yet unknown sites mapped as part of this project.The discoveries promise to be amazing across the land that has seen a parade of cultures come and go.In the future,she hopes other countries will contact her to launch their own satellite surveys.The possibilities are huge.Parcak estimates that there are at least12million potential archaeological sites yet to be discovered.That means the sky is the limit for her project now that it has gotten off the ground successfully.28.What's the purpose of Parcak's project?A.To interview citizens via the Internet.B.To dig out more remains of ancient cities.C.To build databases for unknown cultural heritage.D.To identify unknown ancient sites through joint efforts.29.What do we know about the participants in Peru project?A.They are Internet-equipped volunteers.B.They are well-trained voluntary scholars.C.They are mostly fans of archeology in Peru.D.They are all archaeologists all over the world.30.Why is Parcak's project important to India?A.India lacks thorough archaeological work.B.Indians call for the protection of their rich cultures.C.There's no amazing archaeological discovery in India.D.India needs more relics listed as World Heritage Sites.31.What does the underlined sentence"The possibilities are huge."in Paragraph6mean?A.Parcak's project will become successful.B.Few countries will start satellite surveys.C.There will be amazing discoveries in India.D.More archaeological sites will be identified.DOver2.5quintillion（1018）bytes of data are created each day.Many of them consist of information that would allow people to be personally identified.At the same time that we share our personal information,there is a growing concern with how that information is being gathered,stored,used and shared.While many economies like Canada and the EU have privacy laws dating back to the mid-1990s,changes to data practices in the past five years have motivated governments to review or update existing laws.Changes to privacy laws are being fuelled by growing public concerns with the idea of unrestricted data accumulation and use.For instance,earlier this year,the World Economic Forum found that1/3of global citizens have no idea about how their personal information is used and that trust is lacking.Privacy laws are changing to deal with the real and noticed risks of harm which result from the under-regulated or unregulated data economy.The EU has introduced big reform to laws which are aimed at protecting privacy.The EU's General Data Protection Regulation（GDPR）introduced strict requirements for those that control or process the personal data of the people who live in the EU.The GDPR's stated goals focus on the protection and basic rights of personal information.Certain US states are also entering the ring in the fight for control over personal data.They have passed or are actively considering privacy laws.California is out front.The California Consumer Privacy Act（CCPA）provides greater control to individuals over their personal information.There is a sense that privacy laws are on the near horizon in the US.These are two examples that are actively pursuing more progressive privacy laws.One important consideration is to harmonize global standards for best law practices.This will ease compliance（遵守）across border and provide a valuable signal to the public that governments are keeping pace with rapid change.32.What's the cause of the change of privacy laws?A.A growing need for information.B.Public concerns over data security.C.General awareness of data control.D.Collection of personal information.33.How does Paragraph4develop?A.By giving examples.B.By listing statistics.C.By analyzing reasons.D.By making comparisons.34.What is an important consideration for global law makers?A.The practice of laws in different fields.B.The reflection of reality in different eras.C.The consistency of laws in different regions.D.The adaptation to changes in different societies.35.What is the passage mainly about?A.EU passes new laws for privacy protection.ernments ignore the violation of personal privacy.C.Privacy laws are changing to protect personal information.D.People lack the awareness of personal information protection.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，选项中有两项为多余选项。

Anyone in the world with a computer and Internet access could help discover and protect remains of Peru's rich cultural heritage. The results have been surprising. About 80,000 participants from a hundred countries have identified 19,000 sites that were not in Peru's database. The platform for Peru is still running.If all goes well, the work in India could last for years. "India has had relatively little archaeological work done," Parcak says. Also, the full extent of India's archaeological work has never been mapped completely. Parcak expects her project to make up that. “Wherever we end up going, the crowd's going to be able to see extraordinary things," Parcak says.Thirty six India's cultural heritage relics are already listed as UNESCO World Heritage Sites. Parcak thinks there could be tens of thousands of as yet unknown sites mapped as part of this project. The discoveries promise to be amazing across the land that has seen a parade of cultures come and go.In the future, she hopes other countries will contact her to launch their own satellite surveys. The possibilities are huge. Parcak estimates that there are at least 12 million potentialarchaeological sites yet to be discovered. That means the sky is the limit for her project now that it has gotten off the ground successfully.28.What's the purpose of Parcak's project?A. To interview citizens via the Internet.B. To dig out more remains of ancient cities.C. To build databases for unknown cultural heritage.D. To identify unknown ancient sites through joint efforts.29.What do we know about the participants in Peru project?A. They are Internet-equipped volunteers.B. They are well-trained voluntary scholars.C. They are mostly fans of archeology in Peru.D. They are all archaeologists all over the world.30. Why is Parcak's project important to India?A. India lacks thorough archaeological work.B. Indians call for the protection of their rich cultures.C. There's no amazing archaeological discovery in India.D. India needs more relics listed as World Heritage Sites.31. What does the underlined sentence "The possibilities are huge. " in Paragraph 6 mean?A. Parcak's project will become successful.B. Few countries will start satellite surveys.C. There will be amazing discoveries in India.D. More archaeological sites will be identified.DOver 2. 5 quintillion （1018）bytes of data are created each day. Many of them consist of information that would allow people to be personally identified.At the same time that we share our personal information, there is a growing concern with how thatinformation is being gathered, stored, used and shared. While many economies like Canada and the EU have privacy laws dating back to the mid-1990s, changes to data practices in the past five years have motivated governments to review or update existing laws.Changes to privacy laws are being fuelled by growing public concerns with the idea of unrestricted data accumulation and use. For instance, earlier this year, the World Economic Forum found that 1/3 of global citizens have no idea about how their personal information is used and that trust is lacking.Privacy laws are changing to deal with the real and noticed risks of harm which result from the under-regulated or unregulated data economy. The EU has introduced big reform to laws which are aimed at protecting privacy. The EU's General Data Protection Regulation （GDPR）introduced strict requirements for those that control or process the personal data of the people who live in the EU. The GDPR's stated goals focus on the protection and basic rights of personal information. Certain US states are also entering the ring in the fight for control over personal data. They have passed or are actively considering privacy laws. California is out front. The California Consumer Privacy Act（CCPA）provides greater control to individuals over their personal information. There is a sense that privacy laws are on the near horizon in the US.These are two examples that are actively pursuing more progressive privacy laws. One important consideration is to harmonize global standards for best law practices. This will ease compliance （遵守）across border and provide a valuable signal to the public that governments are keeping pace with rapid change.32. What's the cause of the change of privacy laws?A.A growing need for information.B. Public concerns over data security.C. General awareness of data control.D. Collection of personal information.33. How does Paragraph 4 develop?A.By giving examples.B. By listing statistics.C. By analyzing reasons.D. By making comparisons.34. What is an important consideration for global law makers?A. The practice of laws in different fields.B. The reflection of reality in different eras.C. The consistency of laws in different regions.D. The adaptation to changes in different societies.35. What is the passage mainly about?A. EU passes new laws for privacy protection.B. Governments ignore the violation of personal privacy.C. Privacy laws are changing to protect personal information.D. People lack the awareness of personal information protection.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，选项中有两项为多余选项。

四川省成都市2024届高三第三次诊断性检测文综政治试题-含解析
成都市2024级中学毕业班第三次诊断性检测文科综合政治试题一、选择题：本大题共35小题，每小题4分，共140分。
在每小题给出的四个选项中，只有一项是符合题目要求的。
1. 20世纪80年头初，我国个人电脑的价格高达上万元人民币，远高于当时人们的收入。
尽管价格如此昂贵，供应量却极少。
如今个人电脑性能大大提升，价格也比当时便宜很多，但供应量却增加了不止1万倍。
下列对此说明正确的是①电脑供求状况不受价格变动的影响②电脑需求扩大是供应增加的根本缘由③价值是电脑价格凹凸的确定性因素④技术进步使电脑变得越来越物美价廉A. ①②B. ①④C. ②③D. ③④【答案】D【解析】电脑价格状况受价格变动的影响，①错误；电脑社会劳动生产率的提高是电脑供应增加的根本缘由，②不选；价值确定价格，价值是电脑价格凹凸的确定性因素，③正确；技术进步使电脑的性能提升，生产效率提高，故而技术进步使电脑变得越来越物美价廉，④正确，故本题答案选择D。
【点睛】本题涉及影响价格的因素。
影响价格的因素可从多方面来考虑，主要有以下几方面：（1）商品的价值量。
一般地说，价格凹凸与价值大小成正比，价格是由价值确定的。
（2）供求关系。
供求关系是影响价格的干脆因素。
（3）纸币发行量。
当纸币的发行量超过流通中实际须要的货币量时，就会引起纸币贬值，物价上涨。
（4）货币自身的价值。
当商品价值不变时，商品价格与货币自身的价值成正比，即货币价值上升，则商品价格下降；货币价值下降，则商品价格上升。
（5）市场调整自发性的影响。
市场调整的自发性极易出现哄抬物价等行为。
（6）国家政策的影响。
2. 浙江省永康市桐塘村在开展新农村整治中，巧思妙想，将老厂房进行修缮、设计，改建成民国风格的街道、监狱、大食堂等一系列影视场景，出租场地所得的收益比原来高3倍左右。
这种“腾笼换鸟”的做法体现了①合理利用资源，促进产业转型②改造传统产业，实现产业融合③创新发展思路，推动乡村振兴④优化经济结构，提升工业效益A. ①②B. ①③C. ②④D. ③④【答案】B【解析】这种“腾笼换鸟”的做法体现了合理利用资源，促进产业转型，①正确；材料没有体现改造传统产业，实现产业融合，②不选；这种“腾笼换鸟”的做法创新了发展思路，推动了乡村振兴，③正确；“提升工业效益”在材料中没有体现，④不选，故本题答案选择B。

1、阅读下面的文字，完成小题。
容膝贾大山东门里有个大觉寺，寺内有一方青石，上刻两个大字：“容膝”；又刻一行小字：“晦翁书”。
原来这块石刻放在一个大殿的角落里，尘封垢染，无人问津。
到了八十年代，寺内的工作人员把它拓片装裱，先是文人墨客喜爱，后来平常百姓也争着买。
于是“容膝”拓片除了在寺内零卖，也批发到“四宝斋”。
“四宝斋”就在大觉寺的对面，卖文房四宝、名人字画。
主人是一对年轻夫妇，一个叫文霄，一个叫玉素，一个能写，一个爱画。
“四宝斋”的顾客并不多，卖绿萝卜的老甘却是这里的常客。
老甘是个种田人，认不得几个字，但是非常喜欢“四宝斋”。
他说全城里的买卖，哪一家也不如“四宝斋”的买卖做得文雅，买的文雅，卖的也文雅。
每天，他把放着半笸箩绿萝卜的小车儿朝“四宝斋”门口一撂，就钻到店堂里去了，一边取暖，一边瞅摊，一边看文霄夫妇做买卖。
老甘望着装裱精致的“容膝”拓片，问了一句：“那个黑片子，卖多少钱？”“七十。
”文霄告诉他。
“呀，好贵也！”老甘吐吐舌头，悄悄说。
“写字的人贵。
”文霄也很喜欢老甘，生意不忙了，爱和老甘聊天。
他说“晦翁”不是别人，就是朱熹，南宋的大哲学家。
“老朱有两下子！”老甘说，“这两个字，写得是不赖！”“其实，‘容膝’是陶渊明的话。
”老甘正赞叹着，一个戴眼镜的中年人走进来。
玉素在后面的小屋里说：“对，是陶渊明的话。
”“‘倚南窗以寄傲……’”眼镜背诵道。
“‘审容膝之易安。
’”玉素在屋里接了下句。
文霄一拍手说：“对，是有这么两句！”柜台里面一句，柜台外面一句，屋里一句，三个人津津有味地谈论着。
他们越谈越投机。
眼镜问到“容膝”拓片的价钱时，文霄十分友好地说：“别人买七十，你买……”“我买一幅，也优惠优惠吧！”文霄还没说完，走进来一个胖老头，淡淡的眉毛，疏疏的胡子，披一件细毛羊皮里想挂一幅“容膝”……“三间房屋？”眼镜问。
