广东省化州市2018年第二次高考模拟考试语文试卷
广东省化州市2018年高考第二次模拟考试语文试题一、现代文阅读（35分）（一）论述类文本阅读（本题共3小题，9分）阅读下面的文字，完成1-3题。
词之所以微妙是什么缘故呢？因为词在初起的时候，本来就是那些个诗人文士写给美丽的歌女去唱歌的歌词，没有想把我的思想怀抱理想志意都写到词里边去。
他最初本来没有这种用心，没有这种想法。
写美丽女子的爱情，就是写美丽女子的爱情。
可是，奇妙的事情就是在这里发生的。
每一个人都是带着自己的思想文化教养性格的种种不同的背景的，不管你是欣赏诗歌，还是创作诗歌，都无法避免，你就是你，你无论是解说，无论是创作，都带着自己的背景在其中了。
微妙的事情发生在哪里呢？就是在这些个诗人文士，当他用游戏笔墨为了娱宾遣兴给歌女写歌词的时候，无法避免地把自己的性格思想，在不知不觉之中，隐意识的，自己完全都不知道的，流露表现在爱情的歌词中去了。
这是很微妙的一件事情。
而且，我们有一句俗话说，观人于揖让，不若观人于游戏。
我们要观察一个人，看他揖让进退，他在一个公开的场合，表现得彬彬有礼——当然，因为那是要给大家看的。
可是，当他游戏的时候，因为不用端着架子，不用装腔作态了，所以，不知不觉反而把他更真的自我表现出来了。
词就是有这样一种微妙的作用。
就是说他本来没有要写自己理想志意的用心，只是给美丽的歌女，写一些漂亮的爱情的歌词。
可是他不知不觉地就把他最深隐的本质，这不是拿腔作调说出来的什么伦理道德，而是他自己真正的感情人格的最基本的本质，无意之中，不注意之间就流露表现出来了。
词既有这样一种微妙的作用，因此，王国维在他的《人间词话》里，就为词的性质下了这样几句定义，他说：“词之为体，要眇宜修，能言诗之所不能言，而不能尽言诗之所能言。
诗之境阔，词之言长。
”他说词这种文学体式是“要眇宜修”。
“要眇宜修”出于《楚辞·九歌·湘君》“美要眇兮宜修”，是写湘水上的一个神灵具有一种要眇宜修的美。
这是一种什么样的美呢？《楚辞》有王逸的注解《楚辞章句》，说“要眇”是“好貌”，是一种美好的样子。

【做答案】2018年广东省高考英语听说模拟考试题2PART A Reading AloudFish are masters of the waters. And sailfish are the fastest of them all. Their speed makes them one of the ocean’s most fearsome predators. Off the coast of Mexico, 30 sailfish have surrounded a ball of sardines. To catch their prey requires more than speed alone. In the tightest turns, fins maintain stability. Their sickle-shaped tail powers them forwards, and that extraordinary dorsal fin helps intimidate their prey. To the naked eye, the action is too fast, slowed, their challenge becomes clear. Just picking a target is hard enough.PART B Role Play角色：你是辅导员。

Known （21）its mountain rainforests, savannah woodlands and rolling grasslands, it is home to some of West Africa's most endangered animals.The cameras （22）(spot) some animals that have never been recorded before in the area and others, like chimps, （23）are rarely seen. Stuart Nixon, the Africa Field Programme Co-ordinator at Chester Zoo, said confirmation of the locations of chimps was an important discovery." Gashaka's been regarded for many years as （24）(have)the biggest population of this Nigeria-Cameroon chimp, which is the rarest chimp subspecies,"he said." We consider it the most important population - that's really （25）we need to count it and see what the status of the chimp is right now - that will ultimately affect what we know about this subspecies elsewhere."The chimp （26） (endanger) across its range in Cameroon and Nigeria. Its total population is down to fewer than 9,000 individuals, of which about 1,000 are thought （27） (live)to live within the borders of the national park. "It's an incredible tool to use these camera traps and to reveal that this park - which is a （28）(forget)forgotten wilderness, really, for Nigeria- still has a really important reservoir of important species for Nigeria and Africa in general," said Stuart Nixon.Chester Zoo is funding guards for the rangers and providing training in wildlife onitoring and protection. "This work is helping us learn more about the secrets of one of our last wilderness areas and we must continue to work together to ensure （29）survival for future generations. "（30）all this beauty were lost it would be a terrible tragedy for all."Section BDirections: Complete the following passage by using the words in the box. Each word can only beWhy India's Pink City' is a Photographer's HeavenThe city of Jaipur is one of India's wonders. It 31 some of the country's most decorative royal palaces-elegant structures designed hundreds of years ago that still attract visitors today. Largely built in the 1700s, Jaipur is surrounded by a city wall and several 32 castles. Considered as a commercial center, it was ahead of its time due to the use of grid iron (网格状) city planning.A romantic dusty pink type-which has 33 the city since 1876, after it was painted pink towel come Queen Victoria's husband, Prince Albert-gives Jaipur its 34 as the "Pink City". This 35 beauty is what first brought HongKong-based photographers Victor Cheng and Samantha Wong to Jaipur.Walking in glass skyscrapers for century-old royal palacesand historic castles, the pair-who have 130,000 Instagram followers between them-said that the images they 36 in Jaipur received a lot of response online. "A lot of our followers hadn't seen this side of India, so we're happy we were able to show this side of the country." Cheng said.For the photographers, one of the city's most fascinating features is the light pink coloring of itsbuildings. “The first gate y ou see when you enter are pink, “ s aid Wang “Once you ‘ re through, everything around you varies in different 37 of the color--from bright pinks to reddish browns."The building is a(n) 38 of the City Palace, and its windows allowed royal women to observe street life without appearing in public. One of Cheng's most striking photos shows a straight front of the building and its hundreds of windows. The building's lively coloring also pushed Cheng to take a different 39 to editing than with images of other cities. "I toned down my usual editing process because the pink was so bright in reality," he said, "I wanted the photos to40 the actual color I was seeing myself and to maintain its tone."III. Reading Comprehension Section ADirections：For each blank in the following passages there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.Concerns about the harm caused by “too much” screen time – particularly when it is spent on social media — are widespread. But working out what a “healthy”41 might be is far from easy.Some negative experiences on social media— like 42 how your appearance compares to others— do affect some children. However, this does not mean that technology use in 43 is harmful and it is difficult to make claims about how it will affect different people.Consider the picture painted by a UNICEF review of existing research into the effects of digital technology on children‘s 44 comforts, including happiness, mental health and social life. Rather than stating that social media was harmful, it suggested a more 45 effect.The UNICEF report highlighted a 2017 study that examined 120,000 UK 15-year-olds. Among those teenagers who were the lightest users, it was found that increasing the time spent using technology was linked to 46 comfort — possiblybecause it was important for keeping up friendships. 47 , among the heaviest users of technology, any increase in time was linked to lower levels of comfort. Overall, the UNICEF study suggested that some screen time could be good for children‘s mental health.A broader look at evidence provided by some other high quality studies again suggests the story is not 48 . An early study in 2013 looked at how the television and video game habits of 11,000 UK five-year-olds affected them two years later. It is one of few studies actually 49 the effects of technology over time. It suggested that, compared with children who watched one hour of television or less on a weekday, a small increase in conduct problems was seen among those who watched more than three hours each day. Playing e lectronic g ames, however, was not seen as leading to a greater 50 of friendship or emotional problems.So how much time should our children spend looking at screens? It i s difficult to be 51 as different people spend time online in such different ways. A useful comparison might be with sugar. Broadly speaking, people 52 that too much sugar can be bad for your health. But the effect it might have can depend on many factors, from the type of sugar to the person and the amount. We would not 53 trust anyone who claims to predict how someone is affected by consuming one gram of sugar. The same could be said for 54 usage: the outcomes depend on so many factors that only very 55 predictions are possible.41. A. amount B. comparison C. experience D. medium42. A. accounting for B. boasting of C. commenting on D. worrying about43. A. general B. particular C. private D. public44. A. domestic B. material C. physical D. psychological45.

Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)The cold northern wind here in the streets of Petersburg strengthens my nerves and fills me with delight. I cannot think of the Pole as cold and empty; in my imagination it is a region of beauty and delight. Who knows what strange landscapes and creatures we may find there. I shall satisfy my curiosity with the sight of an unknown part of the world-and walk where no man has before. Thinking of it, I feel the same joy a child feels when he sails his little boat on a voyage of discovery up his native river.This voyage was the favorite dream of my early years. My education was neglected, yet I was passionately fond of reading. Uncle Thomas's library contained only books about exploration, which I read day and night. Finally my thoughts comes to the idea of making a voyage of discovery.Six years have passed sinceI decided on the present voyage. I can, even now, remember the hour when I committed myself to this great enterprise. I began by making my body used to hardship. I went on whale hunting voyages to the North Sea; I voluntarily endured cold, hunger, thirst, and lack of sleep. I often worked harder than the common sailors during the day. Then, at nights, I studied mathematics, the theory of medicine, and sciences of practical importance for a seagoing adventurer. Twice I took jobs as an officer on a Greenland whaling ship. I felt a little proud when my captain asked me to remain with the ship, so valuable did he consider my services. And now, do I not deserve to achieve some great task? My life might have been passed inease and comfort, but I preferred glory to every pleasure that wealth placed in my path.56. What does the author think of the Pole? A.It reminds him of his childhood.B. It must be a region full of surprises.C. It would fulfil his dream to be an adventurer.D. It's too cold a destination with almost nothing.57. To realize his childhood dream, the author got .A. physically prepared by experiencing great sufferingB. spiritually prepared by gaining captain's recognitionC. academically prepared by reading books on explorationD. financially prepared by serving on a whale hunting ship.58.

Module 10.(C)All across America, students are anxiously finishing their "What I Want To Be .." college application essays, advised to focus on STEM (Science, Technology, Engineering, and Mathematics) by experts and parents who insist that's the only way to become workforce ready. But two recent studies of workplace success contradict the traditional wisdom about "hard skills". Google originally set its hiring systems to sort for computer science students with top grades from top science universities. In 2013, Google decided to test its hiring theory by quickly dealing with large amounts hiring, firing, and promotion data collected since the company's establishment. Project Oxygen shocked everyone by concluding that, among the eight most important qualities of Google's top employees, STEM capability comes in dead last. The seven top characteristics of success at Google are all soft skills: being a good coach; communicating and listening well; possessing comprehension into others, being supportive of one's colleagues; being a good critical thinker and problem solver, and being able to make connections across complex ideas.Those characteristics sound more like what one gains as an English or theater major than as a programmer. Could it be that top Google employees were succeeding despite their technical training, not because of it? After bringing in more experts to dive even deeper into the data, the company enlarged its previous hiring practices to include humanities majors, artists, and even the MBAs (Master of Business Administration).Project Aristotle, a study released by Google this past spring, further supports the importance of soft skill seven in high-tech environments. Project Aristotle analyzes data on inventive andproductive teams. Google takes pride in its A-teams, assembled with top scientists, each with the most specialized knowledge and able to throw down one creative idea after another. Its data analysis revealed, however, that the company's most important and productive new ideas come from B-teams comprised of employees who don't always have to be the smartest people in the room.Project Aristotle shows that the best teams at Google exhibit a range of soft skills: equality, generosity, curiosity toward the ideas of your teammates, understanding, and emotional intelligence. And topping the list: emotional safety. To succeed, each and every team member must feel confident speaking up and making mistakes. They must know they are being heard.STEM skills are vital to the world we live in today, but technology alone, as Steve Jobs famously insisted, is not enough. We desperately need those who are educated to the human, cultural, and social as well as the computational.63. The underlined word: “contradict” most probably means ““.A. add toB. back upC. bring aboutD. conflict with64. Google conducted the studies of workplace success in order to .A. determine what makes a workplace-ready studentB. check whether its hiring system serves the purposeC. prove soft skills are more important than hard onesD. impress its competitors with the employees ‘ excellence65. What can be inferred from Project Aristotle?A. Emotional safety enables people to express themselves freely.B. Listening and hearing helps develop problem-solving abilities.C. Learning from mistakes doesn‘t necessarily m ean improvement.D. Those without specialized knowledge can also make inventions.66. Which of the following is the best title for the passage?A. STEM skills our society needs for better educationB. The principal focus students have on application essaysC. The surprising thing Google learned about its employeesD. The soft skills Google programmers lack for career growthSection CDirections: Read the following passage.Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.Car washes have been automated for decades, but companies developing fully autonomous vehicles must rely on a human touch to keep their cars and trucks in working condition.67 For example, soap residue or water spots could effectively "blind" an autonomous car. A traditional car wash's heavy brushes could jar the vehicle's sensors, disrupting their calibration and accuracy. Even worse, sensors, which can cost over $100,000, could be broken.68 Dirt, dead bugs, bird droppings or water spots can impact the vehicle's ability to drive safely.Avis, which has years of experience managing large fleets of rental cars, has been tasked with cleaning and refueling the self-driving van fleet of Waymo, the self-driving arm of Google's parent company. Avis modified three of its branches in the Phoenix area to tend to the Chrysler Pacifica vans." There are special processes that definitely require a lot more care and focus, and you have to clean [the vans] quite often,"69 But other self-driving car companies such as Toyota, Aptiv, Drive.AI and Uber described to CNN that they use microfiber cloths along with rubbing alcohol, water or glass cleaner for manual cleanings.70 This should alleviate some need for manual cleaning. But because autonomous vehicles can have dozens of sensors, Seeva CEO Diane Lansinger doesn't imagine products like this will be able to clean every camera, radar or LIDAR, a laser sensor that most experts see as essential for self-driving vehicles.IV ．Summary WritingDirections: Read the following passage.Summarize the main idea and the main point(s) of the passagein no more than 60 words. Use your own words as far as possible.In one of my earliest memories, I‘m drawing. I don’t remember what the picture is supposed to be, but I remember the mistake. My marker slips, an unintentional line appears and my lip trembles. The picture has long since disappeared. But that feeling of deep frustration, even shame, stays with me.That‘s the thing about perfectionism, a crucially self-defeating way to move through the world. It makes you better at your career and relationships and life in general. Culturally, we often see perfectionism as a positive.But the disadvantage of perfectionism isn’t just that it holds you back from being your most successful, productive-self. Perfectionistic tendencies have been linked to a laundry list of clinical issues: depression and anxiety (even in children), self-harm, social anxiety disorder, eating disorders, and most damaging of all, suicide.“Based upon the 60-odd studies that we‘ve done,the higher the perfectionism is, the more psychological disorders you’re going to suffer,”says York St John University‘s Hill.“Factors often labeled ‘healthy’ perfectionism, like striving for excellence, aren‘t actually perfectionism at all. They’re just conscientiousness（尽职尽责）–which explains why people with those tendencies often have different outcomes in studies. Perfectionism isn ‘t defined by working hard or setting high goals. It‘s that critical inner voice.”Take the student who works hard and gets a poor mark. If she tells herself: “I’m disappointed,but it‘s o kay; I‘m still a good person overall,” th at‘s healthy. If the message is: “I‘m a failure. I‘m not good enough, “that‘s perfectionism.Perfectionists can make smooth sailing into a storm, a brief ill wind into a category-five hurricane. Eventually, the behaviours perfectionists adapt, actually, do make them more likely to fail.V. TranslationDirections: Translate the following sentences into English, using the words given in the brackets.72.他一直提醒自己不要对他人太苛刻。
