A study of 500,000 songs released(发行)in the UK between 1985 and 2015 showed that pop music has decreased in happiness and increased in sadness.

In a report published in the journal Royal Society Open Science,researchers at the University of California examined hundreds of thousands of songs and classified them by their mood."‘Happiness’is going down,‘sadness’is going up,and at the same time,the songs are becoming more ‘danceable’and more ‘party-like,’"co-author Natalia L.Komarova told The Associated Press.

The study found songs in 2014 like "Stay With Me"by Sam Smith,"Whispers" by Passenger and "Unmissable" by Gorgon City to have a "low happiness" trend.However,tracks from 1985 like "Glory Days" by Bruce Springsteen,"Would I Lie To You?" by Eurythmics and "Freedom"by Wham had a high "happiness" trend."The public seems to prefer happier songs,even though more and more unhappy songs are being released each year," the researchers wrote.Apart from the emotional trends,researcheis discovered that dance and pop were the most successful styles of music and that there was a "clear downward trend",with the popularity oF rock beginning in the early 2000s."So it looks like,while the overall mood is becoming less happy,people seem to want to forget it all and dance," Komarova wrote in an email.

It was also found that the "maleness" of songs——the frequency of male singers in popular music——had decreased during the last 30 years "Successful songs are characterised by a larger percentage of female artists compared to all songs,"they Wrote.

This discovery appears at a time when the convcrsation around sex equality in the music industry is at its height,with more male artists and songwriters.

B.Fewer unhappy songs come to light every year.

C.Male singers are better at perrorming pop music.

D.Female artists are less skilled in writing songs.

A new study shows that rising levels of planet-warming gases may reduce important nutrients(营养物质)in food crops

Researchers studied the effects of carbon dioxide on rice,In the experiment,scientists grew 18 kinds of rice in fields in China and Japan.They set carbon dioxide levels to what scientists are predicting for our planet by the end of the century.Rice grown under high carbon dioxide conditions had,on average,13 t0 30 percent lower levels of four B vitamins and 10 percent less protein(蛋白质)The crops also had 8 percent less iron and 5 percent less zinc than rice grown under

normal conditions However,vitamin E leveLs increased by about 13 percent on average.

Earlier studies showed that wheat,rice,field peas and soybeans grown under high carbon dioxide conditions all had Iower levels of protein and mincrais.Scientists predicted that almost 150 million people might be at risk of having too little protein or zinc in their diet by 2050.

The new study suggests a way to lower the nutritional harm of climate change.That is to grow different forms of rice that can adapt to higher carbon dioxide levels.

Parking rules are rules for a reason——and I'm reminding everyone why it's so important to follow them.

My son, Cary, was born with a brain bleeding which leads to difficulties of movement and speech. As a result, Cary uses a wheelchair. A week ago, I was leaving a doctor's appointment with my son when I noticed a car parked over the blue lines of a parking lot, making it difficult for Cary to get into our car. We had to wait for the car owner to come out of the store, who said she didn't know what the lines meant. At the time of his birth, we had no clue to the struggles we would meet with while raising a child with special needs. Sometimes, even people with disabilities don't understand how important it is not to park over the blue lines. And this issue is what we face every day. After talking with many friends and families, we noticed that many people just do not know what those lines are for. My husband and I made the decision to use social media as a way to raise awareness for Cary and his condition. We try our best to be positive instead of blaming people just because they do not know. Our intention is only to remind the public and friends who might not know how important it is to watch the lines when parking. I hope people can be more conscious of their actions and continue helping those in need.

【答案】1. A 2. D 3. D 【解析】 本题以我国省会城市首位度为背景,考查区域地理特征的差异性分析以及区域经济的发展特征。 【1题详解】 根据材料可知省会城市的首位度是某年该省省会城市与该省最大非省会城市经济总量之比,据图判断我国城市省会城市首位度东部沿海省区较低,中西部内陆地区省会城市首位度高,A 正确。经济发达省区由于省会城市与该省最大非省会城市间差异较小,首位度较低,B 错;矿产丰富的省区也有首位度较低的例如呼和浩特,沈阳等,C 错;人口较少的地区例如西藏的拉萨、新疆的乌鲁木齐首位度也较高,D 错,故选A 。 【2题详解】 根据概念省会城市的首位度是某年该省省会城市与该省最大非省会城市经济总量之比,比值越大说明两个城市间之间的经济差异越大,经济发展越不平衡,因此成都城市首位度最高,说明四川省区域经济发展不平衡,D 正确;交通便利、城市水平较高、经济发达会促进区域经济的发展,进而缩小城市首位度,A 、B 、C 错误,故选D 。 【3题详解】 根据材料分析省会城市首位度若大于1,说明该省经济总量最大的 位省会城市;若小于1,则省会城市并不是经济总量最大的省市;据图浙江省杭州市、广东省广州市的首位度大于1,则浙江省、广东省经济总量最大的城市为杭州市、广州市;而福建省福州市和江苏省南京市的首位度小于1,则福州、南京不是该两省经济总量最大的城市,而福建省经济最大量的城市可能为厦门,江苏省经济总量最大的可能为苏州市。A 、B 、C 错误,D 正确。 端砚是中国四大名砚之一,出产于广东肇庆市端溪,距今已有一千三百多年历史,其石质主要为泥质变质岩。其中,带有“石眼”的端砚尤为珍贵,“石眼”是一种特殊的火山尘泥结构。端砚易雕刻、蓄水不涸、发墨快。 据此完成下面小题。 4. 推测带有“石眼”的端砚原石形成的地质过程最可能是 A. 外力沉积一火山喷发一变质作用一地壳抬升 B. 火山喷发一变质作用一外力沉积一地壳抬升 C. 地壳抬升一外力沉积一火山喷发一变质作用 D. 变质作用一外力沉积一火山喷发一地壳抬升 5. 端砚能“蓄水不涸”的主要原因是

方或母方的诞生,也是这个生命诞生的前提。说中华文明可以上溯到新石器时代甚至旧石器时代的认识,显然出于这样的考虑。 然而顾名思义,在“国”前冠以“中”字,“中国”也就有了“中央之城”或“中央之邦”的意蕴。这同时也说明“中国”已并非初始阶段的国家,显然,它一定是一个在当时具有相当的影响力、具有排他性的核心。因而,我们也就不能说最初有多个“中国”,作为发达、复杂的政治实体的“中国”也是不能无限制地上溯的。 考古学家观察到彼时许多古国或部族,大都经历了发生、发展乃至最后消亡的全过程,也即它们各自谱写了完整的生命史的篇章,而只是给后起的中原王朝文明以程度不同的文化给养或影响。到公元前2000年前后,它们先后退出历史舞台,在这些人类共同体和后来崛起的中原文明之间,有一个“连续”中的“断裂”。 按古代文献的说法,夏王朝是中国最早的王朝。一般认为,夏王朝始建于公元前二十一世纪,国家级重大科研项目“夏商周断代工程”,把夏王朝建立的年代定为公元前2070年左右。在考古学上,那时仍属于龙山时代,在其后约两百多年的时间里,中原地区仍然处于邦国林立,战乱频仍的时代,各人类群团不相统属,筑城以自守,“逐鹿中原”的战争正处于白热化的阶段,看不出跨地域的社会整合的迹象。也就

云南昆明市2017届高三复习教学质量检测语文试卷及答案

云南昆明市2017届高三复习教学质量检测 第Ⅰ卷阅读题(70分) 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。 谁是叙述者?根据一般的常识,叙述者就是那个讲故事的人。基于这一点,过去人们常常把一篇小说的叙述者和它的作者等同起来。例如,人们通常把《祝福》中的第一人称叙述者“我”看作是鲁迅本人。其实,叙述者与现实生活中真实的作者并不是一个人。有时,在一个叙事文本中,我们可以同时发现几个叙述者,这几个叙述者的面貌各不相同。在这种情况下,要确定那一个是作者几乎是不可能的。如英国作家乔叟的《坎特伯雷故事集》就是如此。另外,在同一作者的不同作品中,可以有完全不同的叙述者。例如阿城的《棋王》和《孩子王》都是采用第一人称叙述,但叙述者却完全不同。即使叙述者的价值观念、情感倾向与我们了解的作者的情形大致相同,我们也不应当贸然把二者等同起来。正如M?比尔兹利所说:“文学作品中的说话者不能与作者划等号,说话者的性格和状况只能由作品的内在证据提供,除非作者提供实在的背景或公开发表声明,将自己与叙述者联系在一起。”但即令如此,说话人也不是作者,而是“准作者”或最好称之为“作者-叙述者”。 叙述者也不是“隐含作者”。在叙述中,隐含作者的位置可以说介于叙述者和真实的作者之间,如果说现实中的作者是具体的,那么所谓隐含作者就是虚拟的,它的形象是读者在阅读过程中根据文本建立起来的,它是文本中作者的形象,它没有任何与读者直接交流的方式,它只能通过作品的整体构思,通过各种叙事策略,通过文本的意识形态和价值标准来显示自己的存在。隐含作者与真实作者的区别在于,同一个作者可以写作两部甚至更多的作品,每一部作品都包含着一个隐含作者。例如菲尔丁便在几部作品中分别创造了人生态度和价值观念各不相同的几个隐含作者。另外,在现实中,一部作品可以由几个作者共同创作,但一个文本的隐含作者却永远只有一个。 最确切的显示隐含作者存在的是对“不可靠的叙述者”的辨识,我们如何来确定文本中的某些叙述是不可靠的呢?判断的依据就是看它是否与隐含作者的价值观念发生冲突,如果发生冲突,叙述者的态度就是值得怀疑的。《红楼梦》三十四回,王夫人在午睡时发现金钏儿与宝玉调笑,于是抽了金钏儿一耳光,同时不顾金钏儿的苦苦哀求,将她逐出大观园,一场风波过后,叙述者评论道:“王夫人固然是个宽仁慈厚的人,从来不曾打过丫头们一下子,今忽见金钏儿行此无耻之事,这是平生最恨的,所以气忿不过,打了一下子,骂了几句,虽是金钏儿苦求,也不肯收留,到底唤了金钏儿的母亲白老媳妇儿领出去了。”这段话读起来几乎是在为王夫人辩解,他的天性是宽厚仁慈的,她打了丫头并将其撵走,是因为金钏儿与她儿子调情,触犯了她“平生最恨之事”,但我们通过叙述分明看到,此事原本是宝玉先带头的,而王夫人当时只是在假寐,她完全听到了金钏儿与宝玉之间的全部对话,完全了解事情的真相,但她仍然不发慈悲,因此尽管叙述者为王夫人辩护,我们依旧感到王夫人是不公正的,叙述者对王夫人的赞誉也是不可靠的,不足信的。那么是谁有意识地做出这种叙述安排,是谁引起我们对叙述者态度的怀疑呢?这个人就是小说的隐含作者。 (摘编自罗钢《叙事学导论》) 1.下列关于原文内容的表述,不正确的一项是

A.39π B.48π C.57π D.63π 【答案】B 【解析】 试题分析:由三视图可知剩余几何体是圆柱挖去一个圆锥的几何体.表面积为一个圆面圆柱的侧面和圆锥的侧面三部分,其面积之和为π π π π48 15 24 9= + + = S,故应选B. 考点:三视图及圆柱圆锥的面积及运算. 【易错点晴】本题考查的是三视图的阅读和理解及几何体的体积面积的计算的的问题.解答时要充分借助题设中提供的三视图中所给的图形信息和数据信息,先确定三视图所提供的几何体的形状,再根据几何体的形状特征选择所运用的几何体的体积和公式运算求解.如本题所提供的是一个圆柱挖去一同底的圆锥所剩几何体的表面积问题.求解时借助图中所提供的数据可以看出:圆柱圆锥的半径均为3,高为4,再运用直角三角形求出圆锥母线长为5,圆锥的侧面积是解答本题的关键. 6.已知,x y满足约束条件 20, 6, 26, x x y x y -≥ ? ? +≤ ? ?-≤ ? 若目标函数3 z x y a =++的最
