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。

【9题详解】
考查时态和语态。句意：（玩家的）时间花在在岛上捕鱼、采摘水果和种植庄稼。根据句意，此处是短语spend time on …“把时间花在……上”；主语days和spend之间是逻辑上的被动关系，应该用被动语态；文章是说明这一款游戏的内容，全文用一般现在时；因此此处用一般现在时的被动语态be done；主语Days是复数意义，谓语动词应该用复数形式；spend是不规则变化动词，过去分词为spent。故填are spent。

AKnown for its complicated, seemingly wavelike sandstone walls and the rays of sunlight that shine into them, Arizona's Antelope Canyon（羚羊峡谷）is an everlasting attraction for tourists. It's a slot canyon, meaning it formed from water carving it out over millions of years. It sits about 3, 700 feet above sea level and takes its name from the antelope that once lived in it.The canyon forms part of Lake Powell Navajo Tribal Park in the Navajo Nation. The Navajo Nation limits visits to either the Upper or Lower Antelope Canyon to two hours and requires all visitors to be led by authorized guides. If you're planning a trip and need help deciding which area to visit, keep these recommendations in mind.•When: Tours are available twice a day during the we ek year-round, though exact times vary by season；tours are not available on weekends or major holidays.•Cost: Tour companies 5 fees vary, but tickets, including entrance to the park, generally start at around $ 60 for 90-minute tours of Upper Antelope Canyon. Tours of Lower Antelope Canyon tend to be around an hour and generally cost around $ 40 per adult and $ 20 for children.• Must-know tip: Most of Arizona does not follow daylight saving time, though the Navajo Nation, where Antelope Canyon is located, does. Check with your tour operator to confirm the precise time of your tour.Antelope Canyon hosts tons of visitors and, in order to protect the canyon walls from damage, no bags of any kind are permitted in either the Upper or Lower section. Also keep in mind that while most tour companies welcome small children, not all of them will.1. What makes Antelope Canyon attractive?A. Its remarkable height.B. The origin of its name.C.

B Philadelphia's Magic Gardens makes up a folk art center, gallery space, and a nonprofit organization showcasingthe works of mosaicist（镶嵌设计师）Isaiah Zagar.Zagar devoted himself to beautifying the South Street neighborhood in the late 1960s, when he moved to the area with his wife Julia. The couple helped the area by purchasing and repairing some old buildings, often adding colorful mosaics on both their private and public walls. The first such project was Julia's still-busy folk art store, the Eyes Gallery at 402 South Street.Zagar started working on the Magic Gardens in 1994 in the deserted parking lot near his studio. He spent the next fourteen years sculpting multi-layered walls and decorating the 3, 000 square foot space. The installation（装置艺术），primarily consisting of found objects and contributions from the community, finally covers half a city block with countless patterns and colors. It shows Zagar's many artistic influences, as well as the events and experiences of his life.In 2002，the owner of the once-unused parking lot decided to sell the land in response to rising South Street property values. Unwilling to witness the destruction of Zagar's neighborhood art environment, the community rushed to support the artist. His creation, newly titled Philadelphia's Magic Gardens, turned into a nonprofit organization with the intention of preserving and promoting Zagar's works at the site of the Magic Gardens andthroughout the South Street region.The Magic Gardens is now a permanent art institution that is open to visitors throughout the year. Trained guides are available to lead tours of the Magic Gardens and Zagar's surrounding public wall paintings. In addition, it offers monthly mosaic workshops led by Zagar himself, and regularly hosts concerts, dance performances, and other public events.4. How did Zagar help the South Street neighborhood?A. He moved to the area with his family.B. He worked to improve its surroundings.C. He opened a folk art store with his wife.D. He managed to buy all the old buildings.5. What does Paragraph 3 intend to tell us?A. Great achievements of Zagar.B. Special skills of installing art.C. Location of the Magic GardensD. Early history of the Magic Gardens.6. What do the local residents think of Zagar's works?A. They harm environment.B. They can bring in profits.C. They should be removed.D. They are precious treasures.7. What can tourists do in Philadelphia's Magic Gardens?A. Paint the walls on the spot.B. Put on music performances.C. Enjoy some Zagar's works.D. Attend some dance courses.CTelling someone they are not hired is never an easy job, but all hiring managers will face this difficult situation many times in their careers. While everyone fears denial on some level, it is important to understand that not everyone will fit in every job. Further, there are times when the applicant quality will be so great, a decision to reject an applicant may not reflect on that applicant's abilities but the overall quality of the field.There are a number of methods that can be used to get the message across that a person is not hired. In manycases, especially for those who were never called for an interview, a simple form letter may be sufficient. In other cases, where someone may have been called for an interview, a phone call or letter could be chosen to deliver the message that they were not hired. In cases where there may be an ongoing relationship with the person not hired, it may be best to break the news in person, though this has the obvious potential of being more uncomfortable. Above all, it is best to always be honest with those who didn't get the job. Lying is never acceptable.Generally, it is not a good idea to tell someone specific reasons why they are not hired for a job. This can only lead to resentment（怨恨）and regret. However, there may be specific times when this could be a good idea. For example, if an applicant is promising and the hiring manager believes another position will be opening up that suits the applicant's skills, this could be a way to let that person know they may soon have another opportunity.In all cases, even if you feel someone has cheated to obtain an interview, never behave in a way which shows you are superior to them. This is unprofessional and reflects very poorly not only on the hiring manager, but the organization as a whole.8. Why are some applicants refused according to Paragraph 1?A. They are interested in other fields.B. They don't qualify for the position.C. They are afraid of making decisions.D. They lack the courage to face failures.9. How may a not-interviewed applicant be informed of the rejection?A. By receiving a formal phone call.B. By getting a simple form letter.C. By checking a message online.D. By attending a personal meeting.10. In what case will applicants be told exactly why they are not hired?A. They regret applying for the job.B. They demand specific explanations.C. They may be capable of another post.D. They have submitted false information.11. What can be inferred about the position of hiring managers?A. It calls for professional skills.B. It attracts the applicants most.C. It doesn't allow for any mistake.D. It requires honesty and ambition.DFew people doubt the value of developing students' thinking skills. A focus on critical thinking is common in education. In the Australian Curriculum, critical thinking and creative thinking are known as “general capabilities”. The US has a similar focus through their “common core".Many approaches to developing critical thinking are based on Philosophy for Children. One strategy that has a large impact on students' ability to analyse and evaluate arguments is argument mapping, in which a student's reasoning can be visually displayed by capturing the inferential pathway from assumption to conclusion. This type of argument-based intellectual engagement can show high outcomes in terms of the quality of thinking in any classroom. Research also shows deliberate attention to the practice of reasoning in the context of our everyday lives can be significantly improved through targeted teaching.Teachers at one high school in Australia, who have much training in critical thinking teaching methods, developed a task that asked students to determine Australia's greatest sports person. Students needed to construct their own criteria for greatness. To do so, they had to analyze the Australian sporting context, create possible evaluative standards, explain and justify why some standards would be more acceptable than others and apply these to their candidates. They then needed to argue their case with their classmates to develop criteria that were solid, defensible, widely applicable and produced a choice that seized significant and relevant aspects of Australian sport.Researchers looking at the gains made in a single term of teaching critical thinking with argument mapping said the critical thinking gains measured are close to those that could be expected to result from three years of undergraduate education.Students who are taught to think well also do better on subject-based exams and standardized tests than those who do not.In terms of developing 21st century skills, which includes setting up students for lifelong learning, teaching critical thinking should be core business.12. Which of the fo llowing can explain the underlined word “capturing" in Paragraph 2?A. Describing.B. Attracting.C. Designing.D. Blocking.13. What’s the purpose of Paragraph 3?A. To construct the criteria for being great.B. To acknowledge the teachers' outcomes.C. To present how to teach critical thinking.D. To emphasize the importance of reasoning.14. What is the author's attitude toward teaching critical thinking?A. Objective.B. Supportive.C. Doubtful.D. Cautious.15. What does this text imply?A. Teaching methods should vary among schools.B. Research on education deserves more attention.C.Critical thinking should be valued in education.D. Concepts of critical thinking aren't well received. 第二节（共5小题;每小题2. 5分，满分12. 5分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

中学生标准学术能力诊断性测试2020 年 5 月测试英语试卷本试卷共150 分，考试时间100 分钟。
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. 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。

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 ...

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 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 record, it第4页 共8页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 ．IndifferentD ．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 from第5页共8页working 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。

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’r eading, 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．UKschools get more benefits from the exchange program. D．UKteenagers 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。
