四川省凉山州2020届高三第三次诊断检测语文试题及参考答案
凉山州2020届高中毕业班第三次诊断性检测语文第I卷阅读题(共70分)一、现代文阅读(36分)(一)论述类文木阅读(木题共3小题,9分)阅读下面文字,完成1}3题近些年,思维模式十分热门。
在众多的思维方法当中,批判性思维最受关注。
许多人看到“批判”二字,就本能地将之和批评甚至吵架画上了等号;至少,也会觉得这是一种激烈的思维模式,咄咄逼人,让人紧张批判性思维是一种评估、比较、分析、探索和综合信息的能力。
其中“批判”指的是审慎地判断,所以仅仅持有与他人或主流不同的观点并不是批判性思维。
最早给出“批判性思维”定义的人是美国哲学家约翰·杜威杜威在《我们如何思考》中称之为“反思性思维”(reflective thought),并做了这样的定义:对观点和被认同的知识所采取的主动的、持续的、仔细的思考;其方式是探究知识具备什么样的支撑,可以得出什么样的结论从这个定义来看,批判性思维是一种建构性的思维,一种实践取向的思维,并不代表对他人论点的一味话难。
批判性思维要求不能仅仅停留在对信息的盲目吸收这一层级,而是要进行分析、比较与评估,全面地审视之后再去得出自己的认知。
从这个角度来说,批判性思维当然也是一种具有质疑与反驳倾向的思维;但是,这种质疑与反驳首先是“理性”的,它不以单纯的肯定或否定为目的,而以合理的判断为宗旨,以建构与发展为方向。
因此,它的质疑与反驳是基于实证与逻辑的。
批判性思维是一种重要的思维技能,在西方的教育体系中,批判性思维被普遍确立为高等教育的基本目标。
换言之,这是每个接受过高等教育的人,都应当具备的思维模式举一个例子,很多人都有非黑即白的二元思维方式。
在新闻热点事件中,非此即彼的道德绑架处处可见:你在这个问题上支持日本,你是不是不爱国?贩卖儿童罪大恶极,死刑你竟然不支持,你为何这么冷血?其实,爱国与是否支持某国家的某个具体举动没有直接关联;法律代表着程序正义,并不是倾泻愤恨的工具,是否判处死刑,需要足够的证据支撑,并依照严格的审判方能认定这种思维方式就像“不好好读书将来就要扫大街!”“是中国人就转发!”一样,无助于我们更好地理解现实世界批判性思维的要点,就是“理性考察之后再决定”,“理性考察”才是开锁的钥匙;它的内容,或者我们说的“探究和实证”,才是批判性思维的心脏地带。

She's the second eldest of five daughters in the Bennet family and, like the rest of her sisters, she is expected to marry for status and money, not for love. To remain true of herself, she would rather remain single, a concept that was unheard at the time.Nancy Drew She first appeared in 1932 but remains one of the most iconic female characters in all of literature. Created by Edward Stratemeyer, Nancy Drew isn't simply a pretty girl. Instead, the bold, physically strong, and fiercely intelligent Nancy uses her superior intelligence — not her look --- to solve a series of mysteries.Josephine March Jo March is the second eldest daughter in the March family and is a central focus in the novel Little Woman, published by Lousia May Alcott in 1868. Jo struggles with challenges from society's expectations of how women in the 19th century should carry themselves, making her one of literature’ s most daring female characters.Hester Prynne Recognized by some critics as one of the most important characters in female literature, Hester Prynne is the leading character in Nathaniel Hawthorne's 1850 novel, The Scarlet Letter. Married but separated by distance from her husband, Hester has an affair with a minister and becomes pregnant.21. Why would Elizabeth Bennet rather remain single?A. She doesn't want to cheat herself.B. She doesn't want to marry for love.C. She was the eldest daughter of the family.D. She is too clever.22. What is Nancy Drew like?A. Kind.B. Clever.C. Outspoken.D. Proud.23. What is the right order of the timethese females appeared innovels?a. Elizabethb. Nancy Drewc. Josephine Marchd. Hester PrynneA. dcab.B. cdba.C. adbc.D. adcb.BWalk down any British shopping street and you will find shops with strange names. Why is the barbers called "Shearlock Combs"? Why is the opticians (眼镜店)called "Eyediology"? And who decided to name the butchers "Meat you there" and the fish and chip shop "The Plaice to Come"? What's going on?The British love puns (双关语)----as do many other nationalities. Puns are jokes based on words that sound the same. You've probably noticed that many words in English which are spelt in different ways and have different meanings are pronounced in the same way. Think about the name of the restaurant: "plaice" is a kind of fish, so our restaurant is "the place" to eat fish. Butchers sell meat ——so we'll "meet you there" ——and opticians look after our eyes in a scientific way --- so eyed-iology (ideology) is a name that fits. Hairdressers shear (cut) your locks (hair) and comb it —— say the three words together quickly and you have the name of a famous detective. In shop titles and adverts, puns are used to get our attention.Puns are very old. The ancient Egyptians and Romans liked to pun. Shakespeare uses many puns in his plays ——King Richard the Third (the son of York) brings "glorious summer" ——just think about a word that has the same sound as son.Many people enjoy a good pun (pun / fun for all the family! ) —— others hate them. Puns aren't really designed to make you laugh. Here are some puns that might leave you asking for no more puns. Have you heard about the bears who voted in the North Pole? Or the cheetah (猎豹) who couldn't be trusted at cards? Or how about the clever little Australian animal that had lots of koalaifications or the camel with no humps (驼峰) that was called Humphrey (and so was free of humps ... ).Puns can be funny, but they sometimes make important points. Here' s a fashion tip: "skinny genes make skinny jeans": so don't worry if your jeans don't fit --- it's your family's fault!24. Where can you probably enjoy fish and chips, judging from the name?A. Shearlock Combs.B. Eyediology.C. The Plaice to ComeD. Meat you there.25. Why are puns often used in shop titles and adverts?A. It's a long-established tradition.B. They help create a relaxed atmosphere.C. They show the products are of high quality.D. They are good for catching people's attention.26. How does the author make his point in the text?A. By giving examples.B. By making comparisons.C. By following the order of time.D. By describing causes and effects.27. What is the author' s main purpose in writing the text?A. To compare the use of puns in different countries.B. To introduce some popular puns in Britain.C. To stress it is important to understand puns.D. To explain why puns are common in Britain.CIn an ideal world, we might be able to live free from discrimination. But not this one, in which we are constantly dividing everything into “us" and “them".This is especially true during times of fear, like now, when the novel coronavirus is spreading across China and the world. It's a time when “us" means safe and clean while “them" means infectious and risky. Or at least we'd like to believe so.But this is actually a misbelief, which has been fueled and promoted by fear, and sadly, the media. When the outbreak first started, the term “Wuhan virus" was used in some news, creating hostility (敌意)toward people from Wuhan and Hubei as a whole. There were reports of hotels refusing to accept guests from Hubei and some hospitals denied their entry even when they needed treatment for other medical problems.Elsewhe re in the world, German magazine Der Spiegel labeled the virus on its cover as “Made in China". Australia's Herald Sun, meanwhile, printed, “China Kids Stay Home" on its front page, implying that all kids from China are carriers of the virus. It's also reported that Chinese people overseas have faced harassment (骚扰)and even violence.This kind of misbelief is exactly why and when the World Health Organization (WHO) was trying to come up with a name for the disease, it had to be careful. “We had to find a na me that did not refer to a geographical (地理的)location, an animal, an individual or group of people,"said Tedros Adhanom Ghebreyesus, Director-General of the WHO, on Feb 11. And COVID-19 was the final decision.World leaders and institutes are also sharing sensible voices. "There is no place in our country for discrimination driven by fear or misinformation," Canadian Prime Minister Justin Trudeau said at a Lunar New Year celebration in Toronto on Feb 2. Cornell University also sent an email to students and faculty, saying, “We need to remember to care for one another and not make assumptions about others' symptoms or any characteristics of identity."It's understandable that during times like this, we want to go to extreme lengths to make sure we're safe. But fear is never part of the cure. Only love and independent thinking takes you further.28. What is the main purpose of Paragraphs 3 and 4?A. To explain what has brought about misbelief.B. To show how some news media misled the public.C. To compare how different countries responded to COVID --- 19.D. To present what Chinese people overseas suffer from COVID --- 19.29. Justin Trudeau and Cornell University are quoted in the text to ____________ .A. show positive attitudes in face of COVID ---19B. explain why it is important to prevent discriminationC. describe different opinions of the influence of the virusD. introduce measures taken by foreign countries to fight COVID---1930. What's the attitude of the author towards "discrimination"?A. Neutral.B. Supportive.C. Opposed.D. Unconcerned.31. What is the main idea of the passage?A. We should always be willing to care for others.B. Fear and discrimination are as contagious as a virus.C. We shouldn't let misinformation influence our own judgment.D. The media should give people confidence during times of fear.DWe say that technology is a double -edged sword 要 while it brings convenience, it also brings new problems. The sword of "social media" even has a gender preference in its damage: It cuts deeper into girls than boys.Earlier studies have shown that spending too much time on social media is bad for teenagers' mental health. Constantly watching their friends show off "perfect" lives can hurt their own self — esteem. That's not to mention the problems caused by online shaming and bullying.Jean Twenge, a professor at San Diego State University in the US, recently discovered an alarming trend: Since 2010, the number of teenage girls who suffer from major depression 要 showing signs like self-harm and suicide — has increased much faster than that of boys. In an article she wrote at The Conversation, Twenge said social media again, was to blame.For starters, girls use social media more than boys. Boys tend to spend their screen time on games, where they talk to their teammates through headphones. This counts as real human contact. Girls, however, simply type and browse through posts, which is a much more isolated experience. "They're not having a real -time conversation with someone," Mary Fristad, psychologist at The Ohio State University, told NPR.And when it comes to online shaming, girls are also more vulnerable than boys. "Girls face more pressure about their appearance, which could be exacerbated (加重) by social media," wrote Twenge.Shannon McLaughlin, for example, is an 18-year-old from Blackburn College in the US. She shared with the Guardian how social media made her feel depressed. " I was constantly facing women with skinny bodies who were praised for the way they looked. This was only made worse by the diet fixes and skinny culture," she said. But McLaughlin found a solution. She started volunteering with the National Citizen Service, where she made face-to-face contact with people. "It's so easy to forget the importance of real connections when we have hundreds of people that we're trying to impress at our fingertips," she told the Guardian. And she hopes that others "look up from their phones and focus more on the world around them".32. What did Twenge find in her recent study?A. Girls suffered more from bullying than boys.B. Social media does more harm to girls than boys.C. Overuse of social media harms teenagers' mental health.D. Online shaming and bullying are to blame for teenagers' depression.33. Why do girls tend to feel more isolated than boys online, according to Mary Fristad?A. Playing games allows boys to have more fun than girls.B. Girls have less real-time interaction with people.C. Girls suffer more pressure on social media.D. Girls usually desire more contact with others.34. The underlined word "vulnerable" in Paragraph 5 is closest in meaning to " __________ ".A. adjusting oneself wellB. being likely to be at risk of somethingC. fighting back bravelyD. being unconcerned about something35. What does McLaughlin advise teenage girls to do?A. Ignore social media and stop following a diet.B. Make better use of phones for socializing.C. Constantly take part in volunteer work.D. Connect more with the real world.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遥选项中有两项为多余选项Life Lessons Everyone Learns the Hard WayNo matter how much we try to be intellectual, life has its own ways of teaching us the valuable lessons. Though initially we are hurt and very shocked, we eventually learn from those experiences, and mature. 36 And we learn to be always optimistic and happy with the way it is.Lying is harmful. Everyone at some point in life must have definitely realized that lying is a very dangerous thing for the mind, which ultimately affects health, too. Lying makes a man lose the trust of others.37Sometimes moving on is the only option. Some things are very dear to us, and we can't imagine life without those activities or people. But sometimes, circumstances and situations arrange in such a way that it is better to leave something and move ahead. 38 At times, it is better to move on with the memories, rather than stay there and live in a blank space with no possible future.39 In the race of being a perfectionist and an ideal grown-up, every mistake committed by us becomesa mistake in our minds and we become annoyed with ourselves. It is rightly said, "To err ((犯错) )is human." We are all humans, so nobody knows everything, and it is fine to forgive ourselves for the things that went wrong. 40A. It is natural to make mistakes.B. Happiness is the care of everything.C. It is wrong if some things don't work out.D. We understand that life is beautiful with its own flaws (瑕疵).E. And he would finally lose confidence and trust on his own self.F. Everything has its tenure (保有期限), and it is the beauty of it.G. What we should do is try to avoid repeating them or doing any wrong intentionally.第三部分语言知识运用 (共两节,满分 45 分)第一节完形填空 (共20小题,每小题 1.5 分,满分30分)阅读下面短文,从短文后各题所给的A、B、C和D四个选项中,选出可以填入空白处的最佳选项,并在答题卡上将该选项涂黑.Many of us have characteristics coming from our families.

四川省凉山州普通高中2020届高三毕业班第三次高考诊断性检测语文试题(解析版)
绝密★启用前四川省凉山州普通高中2020届高三毕业班第三次高考诊断性测试语文试题(解析版)第I卷阅读题(共70分)一、现代文阅读(36分)(一)论述类文木阅读(木题共3小题,9分)阅读下面文字,完成各题近些年,思维模式十分热门。
在众多的思维方法当中,批判性思维最受关注。
许多人看到“批判”二字,就本能地将之和批评甚至吵架画上了等号;至少,也会觉得这是一种激烈的思维模式,咄咄逼人,让人紧张。
批判性思维是一种评估、比较、分析、探索和综合信息的能力。
其中“批判”指的是审慎地判断,所以仅仅持有与他人或主流不同的观点并不是批判性思维。
最早给出“批判性思维”定义的人是美国哲学家约翰·杜威。
杜威在《我们如何思考》中称之为“反思性思维”(reflective thought),并做了这样的定义:对观点和被认同的知识所采取的主动的、持续的、仔细的思考;其方式是探究知识具备什么样的支撑,可以得出什么样的结论。
从这个定义来看,批判性思维是一种建构性的思维,一种实践取向的思维,并不代表对他人论点的一味诘难。
批判性思维要求不能仅仅停留在对信息的盲目吸收这一层级,而是要进行分析、比较与评估,全面地审视之后再去得出自己的认知。
从这个角度来说,批判性思维当然也是一种具有质疑与反驳倾向的思维;但是,这种质疑与反驳首先是“理性”的,它不以单纯的肯定或否定为目的,而以合理的判断为宗旨,以建构与发展为方向。
因此,它的质疑与反驳是基于实证与逻辑的。
批判性思维是一种重要的思维技能,在西方的教育体系中,批判性思维被普遍确立为高等教育的基本目标。
换言之,这是每个接受过高等教育的人,都应当具备的思维模式。
举一个例子,很多人都有非黑即白的二元思维方式。
在新闻热点事件中,非此即彼的道德绑架处处可见:你在这个问题上支持日本,你是不是不爱国?贩卖儿童罪大恶极,死刑你竟然不支持,你为何这么冷血?其实,爱国与是否支持某国家的某个具体举动没有直接关联;法律代表着程序正义,并不是倾泻愤恨的工具,是否判处死刑,需要足够的证据支撑,并依照严格的审判方能认定。
