内蒙古集宁一中(西校区)2020届高三语文上学期第二次月考试题(无答案)

集宁一中2018——2019年高三语文上半学期第二次月考试题―、现代文阅读(37分〉㈠述类文本阅读(每小题3分,9分)阅读下面的文字,完成1-3题。
①随着不惜一切代价追求一味追求GDP的发展模式暴露出越来越多的问题,政府近来反复强调转换经济增长方式,强调经济和社会的“又好又快”发展,明确把“好”的标准提到首位,而不再简单地重复“发展是硬道理”。
这是一个信号:中国的经济增长方式和社会发展模式将发生重大转变。
面对这一历史性的转变,思想文化界必须回答的问题是:这种转变需要什么样的文化支持?没有相应的文化转型,经济和社会发展模式的转变能够独立完成吗?②很长一段时间以来,我们对于“好”的理解主要集中在环保、低耗、节能等方面,是环境、能源等方面的指标。
节能、低碳、绿色、宜居等等已经被确立为社会发展的重要考核指标。
转变经济增长方式、优化产业结构、大力发展文化产业、建设宜居城市等,也成为政治家和知识分子的口头禅。
③这些当然都是必要的,但是还不够。
因为这些指标基本上还是着眼于经济,“转变经济增长方式”的核心概念依然是“经济”:如果高能耗、高污染的增长方式继续下去,中国的经济就无法持续增长。
但是经济的持续增长是“好”的全部含义么?换言之,如果高能耗、高污染的发展能够持续下去,它就应该坚持吗?我以为不是。
在经济增长的“好”背后还有一个更加根本性的标准,这就是“好生活”。
“好生活”的“好”是一个综合评价指标,它当然应该包括好的经济增长方式,但是又不仅仅是好的经济增长方式,它还应该包括:好(合理)的政治体制、好(优良)的道德环境、好(正确)的价值观和世界观、好(和谐)的人际关系、好(愉快)的心情等。
也就是说,好的经济增长方式之所以好,是因为它和社会生活的其他方面是协调一致,相互支持的。
因此,这个问题不是单纯的经济问题,也不是光靠经济学就能解决的问题。
“好生活”的问题是一个文化的问题。
好生活的问题是一个涉及到社会及政治、经济、道德、哲学等诸多层面的问题,能够概括这些层面的最合适术语,我以为是文化。

马兰花李德霞大清早,马兰花从蔬莱批发市场接了满满一车菜回来,车子还没扎稳,邻摊卖水果的三孬就凑过来说:“兰花姐,卖咸菜的麻婶出事了。
”马兰花一惊:“出啥事啦?”三孬说:“前天晚上,麻婶收摊回家后,突发脑溢血,幸亏被邻居发现,送到医院里,听说现在还在抢救呢。
”马兰花想起来了,难怪昨天就没看见麻婶摆摊卖咸菜。
三孬又说:“前天上午麻婶接咸菜钱不够,不是借了你六百块钱吗?听说麻婶的女儿从上海赶过来了,你最好还是抽空跟她说说去。
”整整一个上午,马兰花都提不起精神来,不时地瞅着菜摊旁边的那块空地发呆。
以前,麻婶就在那里摆摊卖咸莱,不忙的时候,就和马兰花说说话,聊聊天。
有时买菜的人多,马兰花忙不过来,不用招呼,麻婶就会主动过来帮个忙……中午,跑出租车的男人进了菜摊。
马兰花就把麻婶的事跟男人说了。
男人说:“我开车陪你去趟医院吧。
一来看看麻婶,二来把麻婶借钱的事跟她女儿说说,免得日后有麻烦。
”马兰花就从三孬的水果摊上买了一大兜水果,坐着男人的车去了医院。
麻婶已转入重症监护室,还没有脱离生命危险。
门口的长椅上,麻婶的女儿哭得眼泪一把,鼻涕一把。
马兰花安慰了一番,放下水果就出了医院。
男人撵上来,不满地对马兰花说:“我碰你好几次,你咋不提麻婶借钱的事?”马兰花说:“你也不看看,这是提钱的时候吗?”男人急了:“你现在不提,万一麻婶救不过来,你找谁要去?”马兰花火了:“你咋尽往坏处想啊?你就肯定麻婶救不过来?你就肯定人家会赖咱那六百块钱?啥人啊?”男人铁青了脸,怒气冲冲地上了车。
一路上,男人把车开得飞快。
第二天,有消息传来,麻婶没能救过来,昨天下午死在了医院里。
麻婶的女儿火化了麻婶,带着骨灰连夜飞回了上海。
男人知道后,特意赶过来,冲着马兰花吼:“钱呢?麻婶的女儿还你了吗?老子就没见过你这么傻的女人!”男人出门时,一脚踢翻一只菜篓子,红艳艳的西红柿滚了一地。

D.Use the facility in Ardsley.22.What do the last three have in common?A.They are intended for adults. B.They mainly focus on learning.C.They offer various free snacks. D.They have qualified employees. 23.From which is the text most probably taken?A.A website. B.A research paper. C.A newspaper. D.A travel magazine.BWhen we see a person in trouble, the first idea that comes to our mind is to lend a hand. But what if we see an animal in trouble, does the same rule apply?This question was raised after a group of penguins were saved from an icy gully (峡谷) in Antarctica. It was filmed for the BBC wildlife series Dynasties. The film crew were anxious when they saw that a group of penguins had fallen into a gully and been trapped with their young. They built a slope (斜坡) so that a few of the penguins could save themselves.The case has taken the international media by storm. Viewers watching this film let out a sigh of relief. “I'm so glad. I understand not taking action directly, but a helping hand isn't bothering, right?” viewer Kathryn Shaw said on her Facebook.However, others think human interference (干涉) is unnatural. “You can't have sunshine throughout your life. To have done anything else would only make matters worse,”said the show's creator David Attenborough, according to The Times.In this case, however, Mike Gunton, the executive producer of the series, said that this was a oneoff situation. “There were no animals going to suffer by interfering. You weren't touching the animals and it was just felt by doing this .... They had the chance not to have to keep slipping down the slope,” he told the BBC.Such cases are familiar to Paul Nicklen, wildlife photographer for National Geographic. He told Metro, “If it's ever a predator (捕食者) situation, no matter how gutwrenching,_you stay out of the way. Even when you're watching a male polar bear eat a baby bear.”“There's no rule book in those situations. You can only respond to the facts that are right there in front of you,” Will Lawson, the show's director, told Daily Mail.24.What has led to a heated media discussion?A.People's various remarks on penguins. B.The rescue of penguins from a gully.C.Some penguins' sufferings in a gully. D.Ways of filming the series Dynasties. 25.Who holds a positive attitude towards human interference?A.Kathryn Shaw.B.Will Lawson.C.Paul Nicklen.D.David Attenborough.26.Which of the following best explains the word “gutwrenching” underlined in Paragraph 6?A.Putting one in place. B.Making one confused.C.Putting one in danger. D.Making one heartbroken.27.What can be a suitable title for the text?A.Reasons for the Necessity of Lending a Hand to AnimalsB.Suggestions on How to Protect Animals From DangerC.Effects of Human Interference on Dangerous AnimalsD.Opinions on Whether to Help Animals in Trouble or NotCMy twoand fouryearold boys love to win, whether they're racing their bikes down the sidewalk or just finishing their snacks. It's true that those with high status, from world leaders and prize winners to athletes and movie stars, are people we like and respect. A recent study published in Nature Human Beha v iour showed that we seem to have an innate (天生的) preference for highranking people—but only if those people aren't hurtful toward others.Researchers showed toddlers (aged 21 to 31 months) a scene where two puppets (木偶) approached one another from opposite sides of a stage and one bowed to let the other pass first. Asked which puppet they liked better, 18 of the 21 toddlers in the experiment reached for the puppet who had been allowed to pass. Because respect from others is a marker of status, this suggests that children have a preference for those with a higher status—even before age three.However, the results were quite different when two puppets approached one another and one used force to knock the other down before continuing to the other side. In this case, 18 of the 21 toddlers reached for the one who was knocked down. As the researchers concluded, “When approaching others, very young children care not only who wins, but also how.” The previous experiment has shown that toddlers know about social status but this experiment went one step further by proving they have an obvious preference for high status. Since the participants were so young, this might even be an innate human preference.In a word, this new research suggests that young children appreciate people who do well while at the same time doing good to others. So, when my fouryearold thinks that he has to get his shoes on first, I'll keep reminding him that helping his brother so they both finish faster is what winning is all about.28.What do we tend to do according to the first paragraph?A.Seek challenges all the time.

It was a long process, covering thousands of years.The first people to write things down carved symbols onto rocks or shells. These symbols represented people or things.These people who lived a long time ago had simple lives with simple needs. One of the most basic needs was food. Before the introduction of agriculture, people were called HunterGatherers because they hunted animals and gathered nuts and berries for food. To tell each other about how to hunt animals or where to find them, these people drew on cave walls or on animal hides. Soon, people were growing their own crops. They were also using a system of symbols to stand for people, places and things. The best ancient example of this was found in Egypt, where hieroglyphs (象形字) were used. These people believed in many different gods. Each god had its own symbol. Symbols were also used to stand for water, buildings, food, and other parts of life.But these picture drawings and hieroglyphs represented whole words, not just sounds. How did we get an alphabet? Recent research suggests that the idea of an alphabet was first used in Egyptabout 1900 BC.Civilizations that traded with or fought against Egypt were exposed to this alphabet, and the idea spread.The ancient Greeks adapted this alphabet and created their own. The ancient Romans polished it up to a state almost like our modern alphabet. The idea of stringing letters together to make words was born. You can see by looking at letters from the Roman alphabet that these letters survive almost unchanged in our modern English alphabet.This was the case in the Western world. Actually, a similar thing also happened in the East. You can see many examples in such areas' language development.32.Why did HunterGatherers use drawings?A.To assist them in searching for food.B.To put a series of symbols into a system.C.To warn their companions to hide safely.D.To record some methods of growing crops.33.What does the development of the alphabet reflect?A.The difficulties ancient people have learning languages.B.The different kinds of religious beliefs in the same god.C.The poor living conditions and agricultural development.D.The needs of ancient people to survive and communicate.34.How did the ancient Romans influence the alphabet?A.They made improvements to it.B.They created it all by themselves.C.They managed to keep it unchanged.D.They turned it into the modern one.35.What will the author probably write about next?A.The effects of the alphabet on global languages.B.Why the alphabet grew better in Western world.C.How the alphabet appeared in the Eastern world.D.A number of examples of language evolution.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。
