第一部分阅读理解（共两节，满分60分）第一节（共15小题；每小题3分，满分45分）ASummer is that time of this year 2019 when everyone looks to escape from the boring activities of life. So bring your kids to join us to have fun in the summer camp.Outdoor Word Game:All you need to do is setting up many huge letters that can be easily moved. These letters will help kids spell out certain words. Teenagers would also love something like this as it gives them the opportunity to invest their time in learning new words.Spray Painting:To bring out the creativity in a person, an activity centered on spray painting is the perfect way to get those creative juices flowing. All you need to do is providing plain white T-shirts and some cans of colored spray paint. It will be quite surprising to see some of the original ideas that will flow from individuals.Outdoor Twister:A person will be in charge of monitoring the game and will call out colors which can be placed outdoors. Participants have the task of placing either their hands or legs on the same color. A fun and exciting game focuses on hand-eye coordination（协调）.The Maze（迷宫）:One of the funniest games is the hallway maze game where a maze is constructed from either toilet paper or strings of paper. The chosen participant is then asked to make his way through the maze within a limited time without touching paper. This is one of the best and entertaining summer camp ideas for kids and adults also.1．Which activity most probably needs some imagination?A．Outdoor Word Game. B．Spray Painting.C．Outdoor Twister. D．The Maze.2．Which of the following is TRUE according to the passage?A．The maze is made of toilet paper in The Maze.B．You have to spray juice on your T-shirt in Spray Painting.C．Outdoors Twister tests whether you are good at controlling your body movement.D．You have to bring some huge letters to play in Outdoor Word Games.3．Who is the article intended for?A．Parents. B．Children. C．Teachers. D．Teenagers.BWhat makes a person sexy? Looks, talent, public image and how we accordingly view their personality all play into why we find ourselves attracted to certain celebrities and public figures.Every year, People put it all together when they name their “Sexiest Man Alive”. This year, the magazine decided that United States musician John Roger Stephens, better known as John Legend, has the full package.The title comes following some impressive achievements for the 40-year-old. He is among the youngest people to win an Emmy, Grammy, Oscar and Tony award, and the first African-American man to win all four of them. With numerous awards and nominations, an Ivy-League degree, and a handsome face, Legend has gained huge popularity worldwide. However, his dedication to family life maybe what wins over many.After getting married to US model Chrissy Teigen in 2013, Legend is the father of one son and one daughter. He’s not shy about telling the world their love is permanent. On the inside of Legend’s arm, there is a tattoo that says “Chrissy Luna Miles”, the names of his wife and children. In fact, Legend has gained strength from his family since childhood. He still remembers the days when his family would gather around his grandmother’s piano to sing Christmas songs. This inspired his passion for music. His best-known single, All of Me, is a love song to his wife. When he performed it at the 2014 Grammy Awards, many were touched by his delicate voice and the deep love beneath. “The more you know someone, the more you’re inspired by your relationship,” Legend told LA Confidential Magazine. “You have to grow enough to be able to write that song with sincerity and authenticity.”Despite his onstage confidence, Legend had to work to become a legend. As a teenager, he was the smallest kid in class. “I was always less mature, less at ease socially. I had plenty of awkward times,” he told People. “Most of your teenage years, into your twenties, you’re still figuring out who you are, how you present yourself to the world ... Eventually, I think you get more at ease with yourself.” Indeed, knowing who you are and be yourself could be the real key to attractiveness.4．What plays the biggest part in making Legend popular worldwide?A．High-level education. B．Handsome look.C．Efforts put in family. D．Talent in music.5．What does the third paragraph mainly talk about?A．L egend’s hobby as a boy.B．L egend’s family members.C．The secret behind Legend’s success.D．Composing background of the song All of Me.6．What can you infer from the passage?A．Legend is proud of his success in music.B．Legend’s interest in music originates from his family.C．Legend is the first black singer who won the Grammy award.D．Legend received the title “Sexiest Man Alive” before he got married.7．What is essential to attractiveness according to Legend?A．Being more mature.B．Being true to yourself.C．Having onstage confidence.D．Having attractive appearance.CWhat makes people trustworthy? Do they always tell the truth? Do they always keep their promises? In the near future, voluntary blood donations might be used as a clue to prove someone’s trustworthiness.On Nov 19, the National Health Commission (NHC) and other departments jointly released a document urging the social credit system to include voluntary blood donations. An incentive mechanism（激励机制）is also recommended, to provide donors with more conveniences and rewards like preferential treatment in using public facilities or visiting government-run p arks, China Daily reported. “We need to show we care about donors so they feel honored,” Liu Jiang, director of Beijing’s blood donation office, told CCTV.Indeed, donating blood is key to saving many lives. Due to blood’s very limited shelf life, regular blood donations are needed from a sufficient number of healthy people. This ensures that safe blood will be available whenever and wherever it is needed, according to the World Health Organization. However, the notice received mixed reviews on social media, with some people questioning whether it was necessary to include voluntary blood donation in the social credit system, according to the South China Morning Post. The system records things like a person’s career information, and payments for credit cards or other debt expenses are used to tell whether a person or company is trustworthy. People who cannot pay debts on time would have a worse credit score, resulting in more difficulties borrowing money from banks, reported the People’s Daily.Many Sina Weibo users believe that blood donations should be voluntary. They say it has little to do with social credit. Others doubt whether it is appropriate to reward this action because some people would donate blood for reasons other than helping save people’s lives. Guangming Daily commented that only acts closely linked to personal credit should be included in the social credit system. A voluntary blood donor might refuse to pay his or her debts, while someone who doesn’t donate blood might have a perfect credit re cord, it noted.8．What benefit can voluntary blood donors get according to the 2nd paragraph?A．Free park tour. B．Free treatment in hospitals.C．Running in government parks. D．Priority in using public facilities.9．Why are blood donations regularly needed?A．Blood can’t be stored for long.B．Some donated blood is not healthy.C．Fewer people are willing to donate blood.D．More and more people need blood to get treated.10．What can you learn from the last paragraph?A．Many blood donors refuse to pay his or her debts.B．Whoever donates blood will have a perfect credit record.C．It’s right to reward blood donators for they save people’s lives.D．Some people agree that voluntary blood donation shouldn’t be linked to social credit. 11．What’s the author’s attitude to using voluntary blood donations to prove trustworthiness?A．Positive. B．Objective. C．Indifferent D．Negative.DFive years ago, UK schools began to learn Shanghai’s math teaching methods on account of top scores produced by Chinese teenagers in a global academic evaluation. This test is called the Program for International Student Assessment (PISA), run by the organization for Economic Cooperation and Development (OECD). Taking around three hours on computers, it mainly focuses on 15-year-olds’ reading, math and science abilities. Earlier this month, the latest test results were published.Students from Beijing and Shanghai, as well as Jiangsu and Zhejiang provinces, outperformed students from the other 78 participating education systems in mathematics and science by a wide margin. In reading comprehension scores, only Singapore came close. Chinese mainland students first took the tests in 2009, with Shanghai topping the scores. The city claimed the top spot again in 2012.The PISA rankings aroused global interest in Chinese teaching methods and as a result, Britain increased exchanges with Chinese schools to improve its math education. Nearly 600 teachers from Britain and China, mainly from primary schools, have taken part in the ex change since 2014, and around 5,000 of Britain’s 16,000 primary schools have adopted the Shanghai math teaching method. In the latest PISA test, Chinese mainland students averaged 591 points in math —more than 100 points higher than the OECD average. British students averaged 502, jumping from 27th place three years ago to 18th in the math rankings.Philip Avery, director of education for the Bohunt Education Trust, UK, said, “We’ve benefited fromworking with Chinese partners for the high quality of lesson planning and teaching for memorization in China. Our Chinese partners have benefited from our approach to the development of character, focus on innovation and application of knowledge.”However, Zhang Xuanmin, who is in charge of the PISA project in Shanghai, points out that besides basic education, Chinese students still need to improve their social and emotional competencies. 12．Which of the following is TRUE according to the passage?A．UK teenagers are poorly-educated.B．UK schools’ teaching methods are out of fashion.C．Teenagers in Shanghai got higher scores in PISA.D．Teenagers in Shanghai are the best students in the world.13．What does the underlined word mean in the 2nd paragraph?A．Laugh at. B．Look up to. C．get along with. D．be superior to. 14．What’s probably the average math point of OECD in the latest PISA test?A．302. B．490. C．502. D．591.15．What can be indicated by Philip Avery’s words?A．The exchange program is a win-win situation.B．Chinese students still have a long way to go in education.C．UK schools get more benefits from the exchange program.D．UK teenagers have gained a lot of improvement in math learning.第二节（共5小题；每小题3分，满分15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。

1．2019年诺贝尔生理医学奖授予了揭示“细胞如何感知和适应氧气”机理的三位科学家。
他们研究发现肾脏中有专门的细胞可以感受氧气水平的变化，当氧气供应不充足时，低氧诱导因子（HIF-1α）不被降解，细胞内积累的HIF-1α可促进促红细胞生成素（EPO）的合成；氧气供应充足时，HIF-1α合成后很快被降解，具体调节途径如下图所示。
请据图分析下列说法错误的是A．低氧时，HIF-1α进入细胞核联合ARNT与EPO基因调控序列结合，增强EPO基因的表达，使细胞合成更多的EPOB．若将细胞中的脯氨酸酰羟化酶基因敲除，EPO基因的表达水平会下降，细胞合成的EPO量减少C．正常条件下，人体细胞内HIF-1α的含量较低，在医学上可尝试通过提高HIF-1α的含量来治疗人类的贫血症D．高原反应时，EPO 会刺激骨髓中的造血干细胞，使其增殖分化生成大量红细胞，提高氧气的运输能力，该调节方式属于激素调节2．双脱氧核苷三磷酸（ddNTP）属于非天然核苷酸，是桑格-库森法测定DNA 序列的底物。
ddNTP 与脱氧核苷三磷酸（dNTP）的结构如下图所示，根据所学知识判断下列选项错误的是A．若X表示OH，该结构代表的物质dNTP可作为体内DNA分子复制的原料B．若将ddNTP加到正在复制的DNA反应体系中，ddNTP结合到子链后，子链的延伸会立即终止C．ddNTP、dNTP以及磷脂分子的元素组成都为C、H、O、N、PD．若X表示OH，碱基为A时，该物质可为细胞的各项生命活动直接提供能量3．细胞自噬有助于人类更好地了解细胞如何实现自身的循环利用，帮助细胞适应饥饿和应对感染等不良环境。

第一部分阅读理解（共两节，满分60 分）第一节（共15 小题；每小题 3 分，满分45 分）ASummer is that time of this year 2019 when everyone looks to escape from the boring activities of life. So bring your kids to join us to have fun in the summer camp.Outdoor Word Game:All you need to do is setting up many huge letters that can be easily moved. These letters will help kids spell out certain words. Teenagers would also love something like this as it gives them the opportunity to invest their time in learning new words.Spray Painting:To bring out the creativity in a person, an activity centered on spray painting is the perfect way to get those creative juices flowing. All you need to do is providing plain white T-shirts and some cans of colored spray paint. It will be quite surprising to see some of the original ideas that will flow from individuals.Outdoor Twister:A person will be in charge of monitoring the game and will call out colors which can be placed outdoors. Participants have the task of placing either their hands or legs on the same color. A fun and exciting game focuses on hand-eye coordination（协调）.The Maze（迷宫）:One of the funniest games is the hallway maze game where a maze is constructed from either toilet paper or strings of paper. The chosen participant is then asked to make his way through the maze within a limited time without touching paper. This is one of the best and entertaining summer camp ideas for kids and adults also.1.Which activity most probably needs some imagination?A．Outdoor Word Game. B．Spray Painting.C．Outdoor Twister. D．The Maze.2.Which of the following is TRUE according to the passage?A.The maze is made of toilet paper in The Maze.B.You have to spray juice on your T-shirt in Spray Painting.C.Outdoors Twister tests whether you are good at controlling your body movement.D.You have to bring some huge letters to play in Outdoor Word Games.3.Who is the article intended for?A.Parents. B．Children. C．Teachers. D．Teenagers.BWhat makes a person sexy? Looks, talent, public image and how we accordingly view their personality all play into why we find ourselves attracted to certain celebrities and public figures. Every year, People put it all together when they name their “Sexiest Man Alive”. This year, the magazine decided that United States musician John Roger Stephens, better known as John Legend, has the full package.The title comes following some impressive achievements for the 40-year-old. He is among the youngest people to win an Emmy, Grammy, Oscar and Tony award, and the first African-American man to win all four of them. With numerous awards and nominations, an Ivy-League degree, and a handsome face, Legend has gained huge popularity worldwide. However, his dedication to family life maybe what wins over many.After getting married to US model Chrissy Teigen in 2013, Legend is the father of one son and one daughter. He’s not shy about telling the world their love is permanent. On the inside of Legend’s arm, there is a tattoo that says “Chrissy Luna Miles”, the names of his wife and children. In fact, Legend has gained strength from his family since childhood. He still remembers the days when his family would gather around his grandmoth er’s piano to sing Christmas songs. This inspired his passion for music. His best-known single, All of Me, is a love song to his wife. When he performed it at the 2014 Grammy Awards, many were touched by his delicate voice and the deep love beneath. “The more you know someone, the more you’re inspired by your relationship,” Legend told LA Confidential Magazine. “You have to grow enough to be able to write that song with sincerity and authenticity.”Despite his onstage confidence, Legend had to work to become a legend. As a teenager, he was the smallest kid in class. “I was always less mature, less at ease socially. I had plenty of awkward times,” he told People. “Most of your teenage years, into your twenties, you’re still figuring out who you are, how you present yourself to the world ... Eventually, I think you get more at ease with yourself.” Indeed, knowing who you are and be yourself could be the real key to attractiveness.4.What plays the biggest part in making Legend popular worldwide?A．High-level education. B．Handsome look.C．Efforts put in family. D．Talent in music.5.What does the third paragraph mainly talk about?A.Legend’s hobby as a boy.B.Legend’s family members.C.The secret behind Legend’s success.D．Composing background of the song All of Me.6.What can you infer from the passage?A.Legend is proud of his success in music.B.Legend’s interest in music originates from his family.C.Legend is the first black singer who won the Grammy award.D.Legend received the title “Sexiest Man Alive” before he got married.7.What is essential to attractiveness according to Legend?A.Being more mature.B.Being true to yourself.C.Having onstage confidence.D.Having attractive appearance.CWhat makes people trustworthy? Do they always tell the truth? Do they always keep their promises? In the near future, voluntary blood donations might be used as a clue to prove someone’s trustworthiness.On Nov 19, the National Health Commission (NHC) and other departments jointly released a document urging the social credit system to include voluntary blood donations. An incentive mechanism（激励机制）is also recommended, to provide donors with more conveniences and rewards like preferential treatment in using public facilities or visiting government-run parks, China Daily reported. “We need to show we care about donors so they feel honored,” Liu Jiang, director of Beijing’s blood donation office, told CCTV.Indeed, donating blood is key to saving many lives. Due to blood’s very limited shelf life, regular blood donations are needed from a sufficient number of healthy people. This ensures that safe blood will be available whenever and wherever it is needed, according to the World Health Organization. However, the notice received mixed reviews on social media, with some people questioning whether it was necessary to include voluntary blood donation in the social credit system, according to the South China Morning Post. The system records things like a person’s career information, and payments for credit cards or other debt expenses are used to tell whether a person or company is trustworthy. People who cannot pay debts on time would have a worse credit score, resulting in more difficulties borrowing money from banks, reported the P eople’s Daily.Many Sina Weibo users believe that blood donations should be voluntary. They say it has little to do with social credit. Others doubt whether it is appropriate to reward this action because some people would donate blood for reasons other than helping save people’s lives. Guangming Daily commented that only acts closely linked to personal credit should be included in the social credit system. A voluntary blood donor might refuse to pay his or her debts, while someone who doesn’t donate blood might have a perfect credit record, it noted.8.What benefit can voluntary blood donors get according to the 2nd paragraph?A．Free park tour. B．Free treatment in hospitals.C．Running in government parks. D．Priority in using public facilities.9.Why are blood donations regularly needed?A.Blood can’t be stored for long.B.Some donated blood is not healthy.C.Fewer people are willing to donate blood.D.More and more people need blood to get treated.10.What can you learn from the last paragraph?A.Many blood donors refuse to pay his or her debts.B.Whoever donates blood will have a perfect credit record.C.It’s right to reward blood donators for they save people’s lives.D.Some people agree that voluntary blood donation shouldn’t be linked to social credit. 11．What’s the author’s attitude to using voluntary blood donations to prove trustworthiness?A．Positive. B．Objective. C．Indifferent D．Negative.DFive years ago, UK schools began to learn Shanghai’s math teaching methods on account of top scores produced by Chinese teenagers in a global academic evaluation. This test is called the Program for International Student Assessment (PISA), run by the organization for Economic Cooperation and Development (OECD). Taking around three hours on computers, it mainly focuses on 15-year-olds’ reading, math and science abilities. Earlier this month, the latest test results were published.Students from Beijing and Shanghai, as well as Jiangsu and Zhejiang provinces, outperformed students from the other 78 participating education systems in mathematics and science by a wide margin. In reading comprehension scores, only Singapore came close. Chinese mainland students first took the tests in 2009, with Shanghai topping the scores. The city claimed the top spot again in 2012.The PISA rankings aroused global interest in Chinese teaching methods and as a result, Britain increased exchanges with Chinese schools to improve its math education.

第一部分阅读理解（共两节，满分60 分）第一节（共15 小题；每小题 3 分，满分45 分）ASummer is that time of this year 2019 when everyone looks to escape from the boring activities of life. So bring your kids to join us to have fun in the summer camp.Outdoor Word Game:All you need to do is setting up many huge letters that can be easily moved. These letters will help kids spell out certain words. Teenagers would also love something like this as it gives them the opportunity to invest their time in learning new words.Spray Painting:To bring out the creativity in a person, an activity centered on spray painting is the perfect way to get those creative juices flowing. All you need to do is providing plain white T-shirts and some cans of colored spray paint. It will be quite surprising to see some of the original ideas that will flow from individuals.Outdoor Twister:A person will be in charge of monitoring the game and will call out colors which can be placed outdoors. Participants have the task of placing either their hands or legs on the same color. A fun and exciting game focuses on hand-eye coordination（协调）.The Maze（迷宫）:One of the funniest games is the hallway maze game where a maze is constructed from either toilet paper or strings of paper. The chosen participant is then asked to make his way through the maze within a limited time without touching paper. This is one of the best and entertaining summer camp ideas for kids and adults also.1.Which activity most probably needs some imagination?A．Outdoor Word Game. B．Spray Painting.C．Outdoor Twister. D．The Maze.2.Which of the following is TRUE according to the passage?A.The maze is made of toilet paper in The Maze.B.You have to spray juice on your T-shirt in Spray Painting.C.Outdoors Twister tests whether you are good at controlling your body movement.D.You have to bring some huge letters to play in Outdoor Word Games.3.Who is the article intended for?A.Parents. B．Children. C．Teachers. D．Teenagers.BWhat makes a person sexy? Looks, talent, public image and how we accordingly view their personality all play into why we find ourselves attracted to certain celebrities and public figures. Every year, People put it all together when they name their “Sexiest Man Alive”. This year, the magazine decided that United States musician John Roger Stephens, better known as John Legend, has the full package.The title comes following some impressive achievements for the 40-year-old. He is among the youngest people to win an Emmy, Grammy, Oscar and Tony award, and the first African-American man to win all four of them. With numerous awards and nominations, an Ivy-League degree, and a handsome face, Legend has gained huge popularity worldwide. However, his dedication to family life maybe what wins over many.After getting married to US model Chrissy Teigen in 2013, Legend is the father of one son and one daughter. He’s not shy about telling the world their love is permanent. On the inside of Legend’s arm, there is a tattoo that says “Chrissy Luna Miles”, the names of his wife and children. In fact, Legend has gained strength from his family since childhood. He still remembers the days when his family would gather around his grandmother’s piano to sing Christmas songs. This inspired his passion for music. His best-known single, All of Me, is a love song to his wife. When he performed it at the 2014 Grammy Awards, many were touched by his delicate voice and the deep love beneath. “The more you know someone, the more you’re inspired by your relati onship,” Legend told LA Confidential Magazine. “You have to grow enough to be able to write that song with sincerity and authenticity.”Despite his onstage confidence, Legend had to work to become a legend. As a teenager, he was the smallest kid in class. “I was always less mature, less at ease socially. I had plenty of awkward times,” he told People. “Most of your teenage years, into your twenties, you’re still figuring out who you are, how you present yourself to the world ... Eventually, I think you get more at ease with yourself.” Indeed, knowing who you are and be yourself could be the real key to attractiveness.4.What plays the biggest part in making Legend popular worldwide?A．High-level education. B．Handsome look.C．Efforts put in family. D．Talent in music.5.What does the third paragraph mainly talk about?A.Legend’s hobby as a boy.B.Legend’s family members.C.The secret behind Legend’s success.D．Composing background of the song All of Me.6.What can you infer from the passage?A.Legend is proud of his success in music.B.Legend’s interest in music originates from his family.C.Legend is the first black singer who won the Grammy award.D.Legend received the title “Sexiest Man Alive” before he got married.7.What is essential to attractiveness according to Legend?A.Being more mature.B.Being true to yourself.C.Having onstage confidence.D.Having attractive appearance.CWhat makes people trustworthy? Do they always tell the truth? Do they always keep their promises? In the near future, voluntary blood donations might be used a s a clue to prove someone’s trustworthiness.On Nov 19, the National Health Commission (NHC) and other departments jointly released a document urging the social credit system to include voluntary blood donations. An incentive mechanism（激励机制）is also recommended, to provide donors with more conveniences and rewards like preferential treatment in using public facilities or visiting government-run parks, China Daily reported. “We need to show we care about donors so they feel honored,” Liu Jiang, director of Beijing’s blood donation office, told CCTV.Indeed, donating blood is key to saving many lives. Due to blood’s very limited shelf life, regular blood donations are needed from a sufficient number of healthy people. This ensures that safe blood will be available whenever and wherever it is needed, according to the World Health Organization. However, the notice received mixed reviews on social media, with some people questioning whether it was necessary to include voluntary blood donation in the social credit system, according to the South China Morning Post. The system records things like a person’s career information, and payments for credit cards or other debt expenses are used to tell whether a person or company is trustworthy. People who cannot pay debts on time would have a worse credit score, resulting in more difficulties borrowing money from banks, reported the P eople’s Daily.Many Sina Weibo users believe that blood donations should be voluntary. They say it has little to do with social credit. Others doubt whether it is appropriate to reward this action because some people would donate blood for reasons other than helping save people’s lives. Guangming Daily commented that only acts closely linked to personal credit should be included in the social credit system. A voluntary blood donor might refuse to pay his or her debts, while someone who doesn’t donate blood might have a perfect credit record, it noted.8.What benefit can voluntary blood donors get according to the 2nd paragraph?A．Free park tour. B．Free treatment in hospitals.C．Running in government parks. D．Priority in using public facilities.9.Why are blood donations regularly needed?A.Blood can’t be stored for long.B.Some donated blood is not healthy.C.Fewer people are willing to donate blood.D.More and more people need blood to get treated.10.What can you learn from the last paragraph?A.Many blood donors refuse to pay his or her debts.B.Whoever donates blood will have a perfect credit record.C.It’s right to reward blood donators for th ey save people’s lives.D.Some people agree that voluntary blood donation shouldn’t be linked to social credit. 11．What’s the author’s attitude to using voluntary blood donations to prove trustworthiness?A．Positive. B．Objective. C．Indifferent D．Negative.DFive years ago, UK schools began to learn Shanghai’s math teaching methods on account of top scores produced by Chinese teenagers in a global academic evaluation. This test is called the Program for International Student Assessment (PISA), run by the organization for Economic Cooperation and Development (OECD). Taking around three hours on computers, it mainly focuses on 15-year-olds’ reading, math and science abilities. Earlier this month, the latest test results were published.Students from Beijing and Shanghai, as well as Jiangsu and Zhejiang provinces, outperformed students from the other 78 participating education systems in mathematics and science by a wide margin. In reading comprehension scores, only Singapore came close. Chinese mainland students first took the tests in 2009, with Shanghai topping the scores. The city claimed the top spot again in 2012.The PISA rankings aroused global interest in Chinese teaching methods and as a result, Britain increased exchanges with Chinese schools to improve its math education. Nearly 600 teachers from Britain and China, mainly from primary schools, have taken part in the exchange since 2014, and around 5,000 of Britain’s 16,000 primary schools have adopted the Shanghai math teaching method. In the latest PISA test, Chinese mainland students averaged 591 points in math —more than 100 points higher than the OECD average. British students averaged 502, jumping from 27th place three years ago to 18th in the math rankings.Philip Avery, director of education for the Bohunt Education Trust, UK, said, “We’ve benefited fromworking with Chinese partners for the high quality of lesson planning and teaching for memorization in China. Our Chinese partners have benefited from our approach to the development of character, focus on innovation and application of knowledge.”However, Zhang Xuanmin, who is in charge of the PISA project in Shanghai, points out that besides basic education, Chinese students still need to improve their social and emotional competencies.12.Which of the following is TRUE according to the passage?A．UK teenagers are poorly-educated.B．UK schools’ teaching methods are out of fashion.C．Teenagers in Shanghai got higher scores in PISA.D．Teenagers in Shanghai are the best students in the world.13.What does the underlined word mean in the 2nd paragraph?14.What’s probably the average math point of OECD in the latest PISA test?15．What can be indicated by Philip Avery’s words?A.The exchange program is a win-win situation.B.Chinese students still have a long way to go in education.C．UK schools get more benefits from the exchange program.D．UK teenagers have gained a lot of improvement in math learning.第二节（共 5 小题；每小题 3 分，满分15 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’s not shy about telling the world their love is permanent. On the inside of Legend’s arm, there is a tattoo that says “Chrissy Luna Miles”, the names of his wife and children. In fact, Legend has gained strength from his family since childhood. He still remembers the days when his family would gather around his grandmother’s piano to sing Christmas songs.

Do they always tell the truth? Do they always keep their promises? In the near future, voluntary blood donations might be used as a clue to prove someone’s trustworthiness.On Nov 19, the National Health Commission (NHC) and other departments jointly released a document urging the social credit system to include voluntary blood donations. An incentive mechanism（激励机制）is also recommended, to provide donors with more conveniences and rewards like preferential treatment in using public facilities or visiting government-run parks, China Daily reported. “We need to show we care about donors so they feel honored,” Liu Jiang, director of Beijing’s blood donation office, told CCTV.Indeed, donating blood is key to saving many lives. Due to blood’s very limited shelf life, regular blood donations are needed from a sufficient number of healthy people. This ensures that safe blood will be available whenever and wherever it is needed, according to the World Health Organization. However, the notice received mixed reviews on social media, with some people questioning whether it was necessary to include voluntary blood donation in the social credit system, according to the South China Morning Post. The system records things like a person’s career information, and payments for credit cards or other debt expenses are used to tell whether a person or company is trustworthy. People who cannot pay debts on time would have a worse credit score, resulting in more difficulties borrowing money from banks, reported the P eople’s Daily.Many Sina Weibo users believe that blood donations should be voluntary. They say it has little to do with social credit. Others doubt whether it is appropriate to reward this action because some people would donate blood for reasons other than helping save people’s lives. Guangming Daily commented that only acts closely linked to personal credit should be included in the social credit system. A voluntary blood donor might refuse to pay his or her debts, while someone who doesn’t donate blood might have a perfect credit record, it noted.8.What benefit can voluntary blood donors get according to the 2nd paragraph?A．Free park tour.

B．Objective. C．Indifferent D．Negative.DFive years ago, UK schools began to learn Shanghai’s math teaching methods on account of top scores produced by Chinese teenagers in a global academic evaluation. This test is called the Program for International Student Assessment (PISA), run by the organization for Economic Cooperation and Development (OECD). Taking around three hours on computers, it mainly focuses on 15-year-olds’ reading, math and science abilities. Earlier this month, the latest test results were published.Students from Beijing and Shanghai, as well as Jiangsu and Zhejiang provinces, outperformed students from the other 78 participating education systems in mathematics and science by a wide margin. In reading comprehension scores, only Singapore came close. Chinese mainland students first took the tests in 2009, with Shanghai topping the scores. The city claimed the top spot again in 2012.The PISA rankings aroused global interest in Chinese teaching methods and as a result, Britain increased exchanges with Chinese schools to improve its math education. Nearly 600 teachers from Britain and China, mainly from primary schools, have taken part in the exchange since 2014, and around 5,000 of Britain’s 16,000 primary schools have adopted the Shanghai math teaching method. In the latest PISA test, Chinese mainland students averaged 591 points in math —more than 100 points higher than the OECD average. British students averaged 502, jumping from 27th place three years ago to 18th in the math rankings.Philip Avery, director of education for the Bohunt Education Trust, UK, said, “We’ve benefited fromworking with Chinese partners for the high quality of lesson planning and teaching for memorization in China. Our Chinese partners have benefited from our approach to the development of character, focus on innovation and application of knowledge.”However, Zhang Xuanmin, who is in charge of the PISA project in Shanghai, points out that besides basic education, Chinese students still need to improve their social and emotional competencies.12.Which of the following is TRUE according to the passage?A．UK teenagers are poorly-educated.B．UK schools’ teaching methods are out of fashion.C．Teenagers in Shanghai got higher scores in PISA.D．Teenagers in Shanghai are the best students in the world.13.What does the underlined word mean in the 2nd paragraph?14.What’s probably the average math point of OECD in the latest PISA test?15．What can be indicated by Philip Avery’s words?A.The exchange program is a win-win situation.B.Chinese students still have a long way to go in education.C．UK schools get more benefits from the exchange program.D．UK teenagers have gained a lot of improvement in math learning.第二节（共 5 小题；每小题 3 分，满分15 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。
