新疆乌鲁木齐2018届高三教学质量检测（二）语文试题一、现代文阅读论述类文本阅读阅读下面的文字，完成下面小题。

文字是文明发展的载体，记录了一个国家和民族的历史发展进程与经验教训。

古人说，欲灭其国者，必先灭其史。

同样，如果一个国家和民族的文字消亡了，其文明发展的根基也就动摇了。

汉字是中华优秀传统文化能够代代相传并不断繁荣发展的根基。

传承中华优秀传统文化、建设社会主义文化强国，应将汉字教育作为凝神聚力、铸魂固本的战略工程。

清末民初以来，在日本“脱亚入欧”的影响下，中国一些知识分子对中华文化的根基——汉字产生了怀疑。

“汉字落后”论者认为“汉字不灭，中国必亡”，声称汉字的出路在于“拉丁化”；“汉字难学”论者主张汉字“拼音化”与“简化”；“儿童识字有害”论者主张放弃汉字教育。

这些论调在近几十年仍有一定市场，比如20世纪80年代，有人就认为“计算机是汉字的掘墓人”。

当前，汉字教育在实践中遇到的问题主要来自两个方面。

一是面临外语教育的挑战。

现在，英语是学生的必修课，学习英语在一些人看来可以改变命运。

受这种价值观影响，在汉语与英语之间，一些人更重视学习英语，这直接冲击与削弱了汉字教育。

二是面临信息化的挑战。

随着信息化的迅猛发展，人们通过敲击键盘输入汉字的场合越来越多、越来越便捷；在古人眼中曼妙婀娜、形神兼备的汉字，现在变成了电脑键盘、手机屏幕上字母组合的产物。

在日常工作生活中，书写汉字的机会在变少，提笔忘字的时候在增多。

从这些角度来说，汉字面临危机绝不是危言耸听。

汉字是一种象形文字，具有“形、音、义”三要素。

汉字不单单表达概念、内涵、外延等，还给人带来图形、联想、感觉等。

与拼音文字相比较，汉字具有鲜明特色和独特魅力。

学习与理解汉字，应遵循汉字自身的规律和特点。

拼音文字是由字母组成的文字，其教学是用拼音的方法。

我国汉字教学引进了这种方法，并将其作为汉字教学的主要方法。

这种用拼音文字的教学方法来进行汉字教育的理念与实践有哪些优点和缺点，值得我们深思。

新疆乌鲁木齐市2018届高三下学期第二次诊断性测验理科综合化学试题1. 下列说法中正确的是A. “冰，水为之，而寒于水”说明相同质量的冰和水比较，冰的能量更高B. “蜡炬成灰泪始干”中“泪”的主要成分是水C. “南朝四百八十寺，多少楼台烟雨中。

”的“烟雨”是由飘浮在空气中的固体小颗粒形成的D. “榆荚只能随柳絮，等闲摭乱走空园。

”中的“柳絮”和棉花的成分均含纤维素【答案】D【解析】冰转化为液态水是吸热过程，说明相同质量的冰和水比较，冰的能量更低，A错误；“蜡炬成灰泪始干”中“泪”的主要成分是熔化的石蜡，B错误；“南朝四百八十寺，多少楼台州雨中”的“烟雨”是由飘浮在空气中的液体小颗粒形成的，C错误；“柳絮”和棉花的成分均含纤维素，D正确；答案选D。

2. 设N A为阿伏加德罗常数的值，下列说法正确的是A. 0.1mol/LNa2CO3溶液1L所含阴离子数目小于0.1N AB. 常温常压下，3.2gCH4中含有的电子数为2N AC. 1molCl 2溶于足量的水中，反应时斯裂的Cl-Cl 键数目为N AD. 标准状况下，11.2 LCH3CH2OH中含有的分子数为0.5N A【答案】B【解析】从CO32-+H2O HCO3-+OH-看出，1个CO32-水解，生成2个阴离子，所以1L 、0.1mol/LNa2CO3溶液所含阴离子数目大于0.1N A，A错误；常温常压下，3.2gCH4即为0.2mol，含有的电子数为10×0.2=2N A，B正确；Cl2溶于足量的水中，该反应为可逆反应，所以1molCl2溶于足量的水中，反应时撕裂的Cl-Cl键数小于N A，C错误；标准状况下，CH3CH2OH为液态，无法计算出11.2LCH3CH2OH中含有的分子数为0.5N A，D错误；正确选项B。

点睛：1 molCl2溶于足量的水中，反应转移电子数小于N A，因为该反应为可逆反应；1 molCl2溶于足量的氢氧化钠溶液中，反应转移电子数等于N A，因为该反应为不可逆反应。

I stood up look around when a gentle hand touched my shoulder.I turned round to find a wrinkled, little old lady beaming up at me with a smile that lit up her entire being.She said, “Hi handsome. My name is Rose. Can I give you a hug?”I laughed and enthusiastically responded, “Of course you may!” and she gave me a giant squeeze.“Why are you in college at such a young, innocent age?” I asked.She jokingly replied, “I’m here to meet a rich husband, get married, and have a couple of kids…”“No seriously,” I asked. I was curious what may have motivated her to be taking on this challenge at her age.“I always dreamed of having a college education and now I’m getting one!” she told me.After class we shared a chocolate milkshake. We became instant friends. Every day we would leave class together and talk nonstop. I was always mesmerized（迷住）listening to this “time machine” as she shared her wisdom and experience with me.At the end of the semester we invited Rose to speak at our football banquet. I’ll never forget what she taught us.“There is only one secret to staying young. You’ve got to have a dream. When you lose your dreams, you die. We have so many people walking round who are dead and don’t even know it! There is a huge difference between growing older and growing up. If I ameighty-seven years old and stay in bed for a year and never do anything I will turn eighty-eight. Anybody can grow older. That doesn’t take any talent of ability. The idea is to grow up by always finding opportunity in change. Have no regrets. The elderly usually don’t have regrets for what we did, but rather for things we did not do. The only people who fear death are those with regrets.”She concluded her speech by courageously singing The Rose. She challenged each of us to study the lyrics and live them out in our daily lives.5．Why did the lady want to hug the author?A．Because she wanted to challenge her professor.B．Because she wanted to break the ice.C．Because she wanted to find a rich husband.D．Because she wanted to have a college education.6．Which of the following statements agrees with the text best?A．The author enjoyed his experience of riding in the “time machine”.B．The author and the lady soon became close friends.C．Talented people can easily find opportunities.D．Old people usually don’t fear death.7．It can be inferred that Rose is ________.A．a lively college student B．the author’s girlfriendC．a young and innocent lady D．an encouraging song8．What is the life lesson the author learned from his experience?A．An idle youth, a needy age.B．Learn wherever you are.C．A faithful friend is hard to find.D．A man is not old until regrets to take the place of dreams.The Queen has had to say goodbye to one of her longtime companions, her beloved pet corgi Holly, who has sadly passed away aged 13. The corgi will probably be familiar to royal fans who would recognize her from the 2012 London Olympics opening video.The dog was suffering from old age and was put down at Balmoral after suffering from an illness, leaving Her Majesty three surviving pet dogs, Willow and two corgi-dachshund crosses, Vulcan and Candy.According to a spokesperson for Buckingham palace, the Queen was deeply upset by Holly’s passing and she doesn’t like seeing her dogs suffer. Holly had attained a very good age. She gets more unsettled if they suffer and she knows that putting a dog down is often the kindest solution. She was devoted to Holly and wherever the Queen was, the dog was never far behind.Holly was included in one of the portraits for the Queen’s 90th birthday, along with her other three pet dogs. Although the Queen usually has several pet corgis, it was recently revealed that she is keen not to breed（繁殖）any more of the dogs. Monty Roberts, a horse trainer who has previously given advice to Queen, told the Daily Mail, “She wouldn’t leave any young dogs behind if she died. She wanted to put an end to it. Her Majesty had previously named one of her dogs after her friend, but the dog died in 2012. Dogs love for less time than human beings and we know we’re going to lose them—but they are part of the Queen’s family. She’ll be quite upset.”9．What does the author mean by “putting a dog down” in Paragraph 3?A．Helping a dog to survive.B．Letting a dog go.C．Writing down the story of a dog.D．Killing a dog without causing any pain.10．We may learn from the text that ________.A．the pet corgi Candy once appeared in London Olympics opening video.B．the Queen felt upset for the passing away of her beloved pet dog.C．the Queen has decided to reproduce another young pet corgiD．there are altogether three dogs mentioned in the text.11．The text is most probably taken from ________.A．a newspaper B．a film reviewC．a biography D．a documentaryThere’s no doubt that water is vital to any life. About 60 percent of the average adult human body is made of water. This includes most of your brain, heart, lungs, muscles and skin, and even about 30 percent of your bones. Yet there’s little scientific agreement about the exact amount of the stuff an individual should consume each day. So how much water do you actually need to drink to be healthy?You may have heard that you should drink eight 8-ounce glasses of water a day. Yet, the downside of this rule, researchers say, is that drinking water by the glass is not the only way that humans take in it. The “8 X 8” rule essentially overlooks two big sources of daily water consumption. One such source is food. Everything you eat contains some water. Watermelons, for example, are more than 90 percent water by weight. Different diets naturally contain different amounts of waters, and the counts. The other key water sources are other beverages. Non-alcoholic drinks such as coffee, and tea, contain mostly water and all contribute to your hydration（水量）.So, between all the food, water and other fluids you consume in a day, how much water should you aim to take in?The National Academics of Sciences suggests that woman consume a total of approximately 2.7 liters (91 ounces) of warm from all beverages and foods each day and men 3.7 liters (125 ounces). But these are just general guidelines.The truth is, there is no magic standard for hydration—everyone’s need vary depending on their age, weight, level of physical activity, general health and even the climate they live in. The more water you lose, the more water you’ll need to replace with food and drink. If you are looking for concrete advice, though, the best place to look is within. Drink up when you’re thirsty.12．How does the author support the underlined sentence in Para 1?A．By providing facts.B．By asking a question.C．By making a comparison.D．By putting forward suggestions.13．According to the “8 X 8” rule, how much water should we take in a day?A．8 ounces B．64 ouncesC．91 ounces D．125 ounces14．What’s the disadvantage of the “8 X 8” rule?A．The water from both food and other beverages is ignored.B．It includes the amount of water from both food and beverages.C．It does not take water from drinks into account.D．It overlooks the fact that we take in 90% of the water from fruits.15．What can we infer from the final suggestion?A．A man doing tiring physical work drunks less than 3.7 liters a week.B．A person in good health drinks whenever he feels thirsty.C．An overweight male in a hot summer drinks 125 ounces every two days.D．A female eating a lot of watermelons drinks more than 91 ounces daily.二、七选五Here’s how yo-yo dieting affects your body and your mind Yo-yo dieting, also known as weight cycling, occurs when a person experiences periods of weight loss followed by weight gain followed by weight loss and so on and so on.
