广西桂林市、崇左市、百色市2017届高三下学期第一次联合模拟(一模)考试语文试题第I卷阅读题一、现代文阅读(35分)(一)论述类文本阅读(9分,每小题3分)阅读下面的文字,完成1-3题。
无为即无意志——意志哲学视角下老子道性理解李健①老子认为,世界的本原是道,而道是无为的。
历代对于无为的解释比较丰富,王弼注认为无为即“顺自然也”,河上公注认为无为即“不造作”,当代学者有的认为无为即“不妄为”,有的认为是“不人为”。
这些解释都是相通的,即事物都有一个本然状态,而意志的发动都会背离本然状态。
②无欲是无为的具体体现。
欲望的彰显是意志的彰显,是一种危险。
统治者的贪欲是社会危机产生的根本原因,当统治者对外在名利没有追求时,就无需与人相争,“夫唯不争,故天下莫能与之争”老子提出“无欲”是一种哲学上的极致,是一种理想主义,在实践层面,老子其实并非主张“无欲”之禁欲主义,而是主张“少私寡欲”。
③道的无为表现为道隐而不显,即“道隐无名”。
由于道不显现,故人对道的认识是无法穷尽的,凡是有语言表述的道都不是终极恒常的道,“道可道,非常道”,道是无形无象、隐而不显的,而万物是有形有象,是显现的,道可以说是万物的奥秘。
道不能被人的理性认识,道亦不主动地显示于人,道只能靠人去用心体悟,这种体悟需要静穆、靜观④道的无为表现为道无情。
道无情,不分亲疏,“天道无亲”,“大道无情”,天地和圣人也无情,不分亲疏:“天地不仁,以万物为刍狗。
圣人不仁,以百姓为刍狗”,“故不可得而亲,不可得而疏”。
当社会开始讲感情讲仁义时,是社会背离了大道的结果。
所以老子主张“绝仁弃义”。
⑤道的无为表现为道不干预、主宰万物。
道虽然生了万物,“道生一,一生二,二生三,三生万物”,但道并不干预、主宰万物作为最完满的统治者——圣人,遵循道的法则,对人民也不采取干预和主宰,人民仅仅知道圣人的存在,而不知其作为,圣人顺应万民的本然状态,不敢发端自己的意志,“以辅万物之自然,而不敢为”。

Libby loves cornering her own pet until one day itty’s patience runs out. As he r cat taes cover under the bed, Libby comes to realie that pets lie being bossed around by “big peo-ple” as much as she does. The humorous tale encourages children to treat their pets better.21. What do the four boos have in common according to the tet?A. They are all hardcover.B. They are all written for ids.C. They are all rich in colorful pictures.D. They all provide tips for raising pets.22. The third boo is mainly about .A. an interview between a child and a smart catB. a humorous tale between a girl and her pet catC. a shelter cat finding the right ownerD. a clever cat without friends or a home23. Who is adopted by a shelter worer?A. Lucy.B. Bernard.C. The mutt dog.D. The little cat.BSpeluners (热衷勘探洞穴的人) who eplore caves often say they can see their hands move in the dar. A new study suggests those cavers aren’t hallucinating. It finds evidence that the brain sometimes creates visual “images” without input from the eyes.The study bases its conclusion on an eperiment anyone can try. Find a dar place or visit the nearest, darest cave. Net, wave your hands in front of your face. Can you see them?Many people can, which researchers report in a study. Moving a hand causes cell activity in areas of the brain involved in controlling hand motions. The brain may translate that activity into sight, even in total darness, the new study concludes. It doesn’t matter that someone’s eyes didn't actually see the moving hands. The brain seems to mae up for the lac of light and “sees” the hands because it nows so well that such a common body movement would loo lie.By sensing the action, the brain “nows” where a moving hand is and, as the result show, it actually produces the epected visual image. Normally, when someone watches a moving object, his eyes will move smoothly to follow the action. So in the new trials, the scientists used computeried devices to monitor a volunteer’s eyes during the eperiment process. And the people who claimed they saw hand movements in total darness showed such smooth eye movements.Those eye movements suggest the brain fooled the eyes into believing they were following the motion that the brain said they ought to be seeing. If volunteers had only imagined their own hand movements, their eyes would not have responded this way, the researchers said.Not all scientists agree. David Adam is a psychologist. He offers another eplanation. Some studies suggest people s eyes may move smoothly even when they imagine seeing movements. “If true, then the ability to clearly imagine images, not on the strength of any connection between vision-sensitive and motion-sensitive parts of the brain,” he said.24. The underlined word “hallucinating” in Paragraph 1 probably means “”.A. seeing imaginary picturesB. creating a roleC. maing a judgmentD. telling the truth25. The third paragraph is developed mainly by .A. maing comparisonsB. providing the cause and effectC. telling an interesting storyD. maing predictions26. According to David Adam,the ability to “see” without light may be decided by.A. the position of the object in the darB. how accuracy one can see the movementsC. how clearly one can imagine imagesD. the connection between different parts of the brain27. What’s the b est title for the passage?A. Moving eyes freelyB. The secrets of the brainC. Eploring caves in darnessD. Seeing without lightCI’ve seen countless patients arrive complaining about gut (肠道) problems. Once we fied their diets and solved their gut problems, their seasonal allergies (过敏) also disappeared!One patient struggled with allergies. She nearly died twice from allergies. She arrived at my office on 42 different pills; yet,she still felt awful. It turned out that she had leay gut(肠漏症). We healed her leay gut and calmed down her allergies. Thanfully, after si wees, she was able to stop the 42 pills she used daily. For her and countless other patients, a ey solution involves getting your gut healthy. To do that and remove seasonal allergies, I’ve f ound these four ways really helpful.Replace bad with good. A healthy diet becomes the first step for a healthy gut. Tae out the bad and put in the good. Remove wheat, com, dairy, soy and alcohol. Eat a high-fiber diet. Avoid anything that has sugar or trans fats (反式脂肪). Focus on eating healthy fats from olive oil, nuts,and omega-3 fats lie those found in small fish.Use powerful gut—healing nutrients,including probiotics (益生菌). Other gut-healing nutrients include fish oil.Manage stress. A mind-body disconnection can mean being stressed out and tired, and your gut can be vitiated and your seasonal allergies will become worse as a result. Do some eercise that can help you rela lie yoga everyday.Get enough sleep. A lac of sleep can also increase your ris of diabetes, leading to obesity. Aim for at least eight hours of good sleep every night.If you follow the ways listed above, surely you’ll have healthier gut, reducing the chance of suffering seasonal allergies as a result.28. What does the author probab ly thin is the ey to solving that patient’s problem?A. Healing her gut problem.B. Taing 42 different pills.C. Calming her down.D. Finding a boyfriend.29. What does the author mean by saying “replace bad with good” in the third paragraph?A. Replace bad steps with good ones.B. Replace unhealthy food with healthy food.C. Replace leay gut with healthy gut.D. Replace bad friends with good ones.30. The passage is liely to appear in a (an) .A. news reportB. tet booC. medical journalD. advertisement31. What is the tet mainly about?A. How to enjoy a healthy lifestyle.B. How to avoid long-term diseases.C. How to mae good use of nutrients.D. How to get rid of seasonal allergies.DI don’t recall hearing fairy tales as a very small girl, though when I was 9 or 10, I often read the Grimm ones. The stories are usually very short and I could finish one easily. The stories showed a very different world to me. The magic seemed unbelievable, but I remember I was often scared when I was reading the stories.Now when I re-read the stories, I really thin many of them are not suitable for little ids to read. An evil queen is forced to dance herself to death wearing red-hot iron shoes; a prince falls in love with a dead girl and begs permission to tae ownership of her lifeless body; a man leaves his children in a forest starving after his wife tells him to do so. Can you imagine how a id would feel when he or she is reading such stories?Supreme Court Justice Antonin Scalia argued that California shouldn’t be permitted to ban the sale of violent video games to ids. He thought the games were not more violent than fairy tales. “Han-sel and Gretel (children) ill their captor by baing her in an oven,” Scalia wrote. He’s not the only one who feels that way. “I’m 51,” writes one parent on a website. “I remember my parents told me many of these fairy tales atbedtime and that they scared me to death.” A commenter at the New Yor Times writes, “They were scary when I was a id, and now they seem creepy and i nappropriate for an adult.”32. When the author was 9 or 10 years old, she .A. often read Grimm fairy talesB. often read long storiesC. didn’t lie reading short storiesD. showed no interest in stories about magic33. What do the eamples given in Paragraph 2 mainly show about Grimm fairy tales?A. They are thrilling to read.B. They were written for adults.C. They are unsuitable for little ids.D. They teach very good life lessons.34. In Antonin Scalia’s opinion.A. some fairy tales are too violentB. violent games are based on fairy talesC. violent video games should be bannedD. fairy tales should not be allowed to read35. What does the underlined word “creepy” in Paragraph 3 mean?A. Funny.B. Normal.C. Frightening.D. Disappointing.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。
