2.【答案】C【解析】由材料“执政官委御史台弹奏,尚书以下听长官纠劾以闻”、“自宰臣至百官,自三省至百司,任非其人,事有失当,谏官皆得谏正”可知宋代无论是御史还是谏官都可以弹劾宰相,是皇权不断加强的表现,说明专制主义集权高度发展,故选C项;材料无法体现出文官对武官的牵制,排除A项;监察宰相职权不等于削弱宰相职权,排除B项;唐代的三省六部制,中枢制衡机制已日渐成型,排除D项。

5.【答案】A【解析】根据材料中“转此大法轮”“甘泽高下普”可以判断是灌溉工具筒车,筒车利用水力来进行农田灌溉,故A项正确;筒车节省了人力但不能调节水的流量,故B项错误;筒车是灌溉工具并没有提高耕作技术,故C项错误;筒车出现于唐代而不是宋代,故D项错误。

6.【答案】D【解析】不断扩大,与材料中“18?世纪”“国外金银比价”基本稳定不符,故A项错误;材料中无法体现茶叶贸易,故B项错误;完全封闭会保持金银比价差距,而不会缩小,故C项错误;白银大量流入,会改变金银比价,与材料中“中外金银比价”趋同相符,故D项正确。

大象天成大联考--全国名校联盟2018届高三第二次考试英语试题

大象天成大联考--全国名校联盟2018届高三第二次考试英语试题学校:___________姓名:___________班级:___________考号:___________一、阅读选择England continues to be one of the most popular tourist destinations in the world. London in particular is one of the most visited cities and draws people in with its appeal, history, and pubs. England’s smaller cities, like Bath and Oxford, are equally as attractive with a lot of culture and fewer crowds. Liverpool, birthplace of The Beatles, has a rich musical history. The countryside has wonderful natural beauty. Here are some tips on traveling in England.Free museums—Public museums offer free admission in every city throughout England and the UK. It’s a great way to learn about the country’s most influential artists and history, and spend a rainy day without paying a cent.Book early—Book all transportation well in advance, even if you don’t plan to use it. Fares can be around £2 with a little planning. The Megabus not only runs buses but also provides trains throughout England and is the best choice for cheap travel throughout the country.Pub food—Eating in England can be quite expensive, but for good cheap and filling meals, visit the local pubs, where you can get a good meal for less than £10. Besides, the pubs are a great way to meet people!Get a Taste of UK card—The Taste of the UK card offers up to 50% off at selected restaurants. You don’t need to be an English to get the card, and you needn’t pay the first month’s membership fee, which is perfect for most travelers.Take a free walking tour—Many major cities in England offer free walking tours. They usually last a few hours and are a great way to see the city.1.Compared with London, Oxford is .A.more appealing B.less crowdedC.larger in size D.richer in history2.Why is eating in local pubs suggested?A.The price of food is low there.B.The chance of meeting stars is high there.C.The service is excellent there.D.The dining atmosphere is perfect there.3.What can be known from the text?A.All museums in the UK are free of charge.B.The best way to travel around England is by bus.C.Free walking tours are available in only some cities in England.D.Holders of the Taste of UK card can enjoy discounts at all restaurants.Two summers ago I was about to turn fifty and wanted to do something I’d never done before. My daughter Bailey thought skydiving (跳伞) would be perfect for me. I can promise you that of all the things I was thinking of doing, jumping out of an airplane never came close to making the list. As I age, I seem to have developed a growing fear of heights.After several requests from my daughter, I finally said yes and she looked almost shocked.I told a friend what we were doing, then we set off. We had a 3-hour drive to the jump site. We drove through some beautiful countryside, but then we passed a small cemetery(墓地). Then we passed another cemetery and another one. I asked if so many people died jumping out of airplanes in this area that they needed to keep building more cemeteries to bury all the bodies!As we squeezed into the little plane, I tightly held the right hand of my partner Ronnie. The short ride to altitude was cruel for me. As Bailey stepped to the door, she looked back at me and said “Dad, I’m sure you can do it!” I said yes as she rolled out. I immediatel y looked behind me and said “RONNIE I AM NOT FEELING GOOD!” He said, “It’s going to be great. Besides, it’s too late now anyway”, and we jumped out.The next five minutes were some of the most amazing of my life. It was so beautiful and peaceful—except for the parts where I was screaming. I prayed to God for the parachute (降落伞) to open, but mostly I told Him how thankful I was for my life and being with me through good and bad.4.What can be inferred about the author from the text?A.He skydived for the first time at the age of 48.B.He jumped at his daughter’s recommendation.C.The older he gets, the less fearful of heights he is.D.Never had he considered attempting to do skydiving.5.What’s the author’s main purpose of mentioning cemeteries in Paragraph 2?A.To tell how determined he was. B.To show how rough the trip was.C.To express how scared he was then. D.To prove how lonely the jump site was. 6.What did Bailey do for her father before she skydived?A.She played a joke with him. B.She gave him encouragement. C.She comforted him constantly. D.She offered him useful guidance. 7.How did the author behave after jumping out of the airplane?A.He enjoyed himself. B.He stayed quite calm.C.He breathed out in relief. D.He kept fearing for safety.Movies are a great means of entertainment for many. There are some advantages of watching movies. Comedies, for example, help reduce your blood pressure. Laughter for 15 minutes during a film makes your blood vessels (血管) wider. Besides, when you watch a sad movie, you’re more likely to come away from it thinking about loved ones and feeling happy about what you have.Watching movies can make you creative. A study shows that young children, who watched the use of magic in Harry Potter, score significantly higher in a creative thinking test than children who watched something else. Moreover, movies are very useful for strengthening people’s mental health. They enable people to take time to really relax and temporarily forget about their daily concerns and problems.H owever, watching movies aren’t always beneficial. Studies have shown that some people get real pleasure out of being scared by horror movies, but in various ways they may be risking their physical and mental health without even knowing it. When you watch a tense scene in a movie, your heart rate and blood pressure increase. Meanwhile this change in your brain chemistry reminds you of times when you were in a similar state, even if you have no idea you even had those memories. So if something horrible happens to you, being scared again by a movie can unintentionally make you experience it once more.Scientists, politicians and parents have debated for decades if being exposed to movie violence leads to actual real-life violence. Overall the answer to that is probably still up in the air, but a new study seems to prove that watching aggression on screen can contribute to being a bully (土霸) in real life, even if it is just in the short term.In conclusion, certain movies play a positive role, but not all movies do. It depends completely on the subject of the movie. So it’s always advisable to choose the movies concerning something positive.8.How does watching sad movies benefit us according to the text?A.It makes us content with our lives.B.It rids us of unhappy memories.C.It reduces our risk of illness.D.It develops our creativity.9.What can we infer about watching horror movies from the text?A.It has more advantages than disadvantages.B.It has gained popularity around the world.C.Plenty of people ignore its health benefits.D.All people don’t realize its disadvantages.10.What does the underline d part “up in the air” in Paragraph 4 mean? A.Meaningless. B.Attractive.C.Uncertain. D.Obvious.11.What does the author advise us to do to reduce the passive effect of movies?A.Enjoy movies with more companions.B.Make a wise choice of what to watch.C.Try our best to watch movies less often.D.Raise our ability to tell right from wrong.Anger itself is neither good nor bad. It’s what we do when we’re angry that matters. Anger is a tool that helps us to read and respond to the social situations that bother us. But how can we keep it under control?It’s normal to think that getting angry is bad and many times we punish ourselves for doing so. But contrary to popular belief, research indicates that anger increases optimism, creativity and efficiency. In addition, studies suggest that anger can lead to more successful negotiations at work, as well as in our personal lives.In fact, suppressing(抑制)anger can be very bad for your health. In this sense, Dr. Ernest Harburg performed a study by monitoring a group of adults and their capacity(最大容量)for anger. What he found is that the men and women who suppressed their anger as a response to an unfair attack had a higher risk of developing bronchitis or suffering from heart attacks , and were more likely to die before their colleagues who let their anger surface when they felt bothered.When anger arises, we feel the need to either prevent or put an end to this powerful feeling for the benefit of our welfare or the welfare of those we care about. But this act of kindness, mercy, love or justice isn’t beneficial in this way. However, it’s certainly a good thing to be cautious when anger begins to surface. Expressing your anger can be appropriate with certain people at certain times. The question lies in how to do it without losing control. The key to expressing your anger is finding the appropriate tone for expressing what it is that upsets you. But to avoid unnecessary shouting, hitting, or other violent reactions, it’s worth taking a moment to step back and think, even though we may be in the middle of an argument with someone.12.What do people generally think of anger?A.It is an important tool. B.It is a bad feeling state.C.It increases our happiness. D.It helps in social situations. 13.What does Dr. Emest Harburg’s study imply about anger?A.It needs a way out. B.It should be avoided.C.It can cause sudden death. D.It must be kept under control. 14.What does the author suggest we do when we’re angry?A.Find out its cause. B.Pretend to ignore it.C.React to it violently. D.Express it reasonably.15.Which of the following can be the best title for the text?A.Ways to Control Anger B.Benefits of Mild AngerC.Showing Anger Properly Counts D.Anger Does Affect Health二、七选五In a world full of uncertainty, having at least one thing you can count on is important. 16.For others it could be reading or running. For me, however, it is always art.Creating can be difficult, but that’s what makes art special. You can start your project with what you want and you can change your mind many times.17.Art has taught me to be patient with myself.If I could name my favourite thing about art, it would be that no two pieces are the same. Many people try to follow one another to be just like them, but that’ll never happen.18.Art has taught me that before anything, be yourself. You may be a little too colorful for some people but to others you’re exactly the rainbow they’ve been looking for.19.The way certain colors mix together to make a new shade can paint an entire picture in your mind. You can learn about the world if you just pay attention. The small things you observe could be your inspiration.Listen, feel and see more, it will fascinate (使入迷) you how much more you appreciate the small things around you.Art is seen differently by everyone. However, one thing in common is creativity. You don’t need to be good at painting to enjoy something beautiful. Be ready to be patient, be yourself and be good at observing.20.A.The beauty of art is in the details.B.I’ve learned some lessons from creating.C.If so, there’ll be no limits on what you can create.D.It’s something that nothing or no one could take away.E.There’ll always be certain things that make them unique.F.The only thing that gives me any piece of mind is painting.G.But no matter what, there will always be a finished product.三、完形填空One day, Luke Fortune drove from Oregon to Portland, where he parked his car in a paid garage overnight.

参考译文: 谢安,字安石。最初被司徒府征召,授予著作郎的官职,他以身体有病为由推辞了。谢
安住在会稽,和王羲之、许询、支遁一起游玩交往。外出就在山水间捕鱼猎禽,回家就吟诗 作文,没有做官的心意。他曾经和孙绰等人乘船出海,大风起,巨浪涌,大家都很害怕,只 有谢安吟啸自如。船夫认为谢安很高兴,仍然向前划个不停。大风加剧,谢安慢慢地说:“这 样的话什么时候回去呢?”船夫听了这话就往回走了。大家都佩服谢安的雅量。当时谢安的 弟弟谢万被罢黜,谢安才萌生了做官的心意,这时他已经四十多岁了。征西大将军桓温请谢 安做司马,他从新亭出发,朝中人士都去送他。中丞高崧和他开玩笑说:“您累次违背朝廷 旨意,隐居到东山,大家在一起讨论这件事说,安石不肯出来做官,老百姓将会怎么样呢? 老百姓都像您一样又怎么样呢?”(听了这话),谢安很惭愧。到了后,桓温很喜欢他,言说 生平,相谈甚欢一整天。他走了后,桓温问左右:“你们曾看见过我有这样的客人吗?”简 文帝驾崩,桓温大摆兵阵,想要谋篡晋的皇位,召唤谢安和王坦之,要在座中杀了他们。王 坦之很害怕,问谢安有什么计策。谢安神色不变,说:“晋朝皇位的存亡,就取决于我们去 的这一趟。”见了桓温后,王坦之汗水沾湿了衣服,手板都拿倒了。谢安从容不迫在席间坐 定,对桓温说:“我听说诸侯遵循道义,让军队镇守在国家边境,明公您又何必把人安置在 墙后面呢?”桓温笑着说:“正是不得已这样做罢了。”于是和桓温笑谈了很长时间。王坦之 一开始和谢安齐名,到这件事后才知道王坦之不如谢安。当时苻坚兵力强盛,战场上颇有忧 患,诸位将领相继败退。谢安派弟弟谢石和侄儿谢玄等随机应变和敌军交战,常打胜仗。后 来苻坚率军号称百万,在肥水驻扎,京城震惊恐慌。于是任命谢安为征讨大都督。谢玄进房 间问他计策,谢安神色平和,毫不慌张,回答说:“我心里已经有谋划了。”接着就没声音了。 谢玄不敢再说,就让张玄再去请教。谢安于是就下令坐车外出去了山间别墅,召集亲朋好友, 以别墅为注和张玄下围棋。谢安平时棋艺不如张玄,这天张玄心中害怕,就和他下了个棋逢 敌手,还不能取胜。谢玄在前线打败苻坚后,有驿站传送的战报送达,谢安正在和客人下围 棋,看完信,就拿了放在床上,毫无欣喜之色,像刚才一样继续下棋。客人问他,他缓缓地 回答说:“小子们打败了敌人。”下完以后,回到房间,心里太过高兴,过门槛的时候把木屐 齿弄折了都不知道。他故作镇静到了这样的程度。谢安虽然受朝廷倚重,然而归隐东山的志 向始终没有改变,常常在言语表情中体现出来。高雅的志向没有实现,后来就得了重病。不 久去世,当时 66 岁,谥号为文靖。

但近几年来,深圳部分制造业工厂出现倒闭和撤离,企业存活时间短,区域转型和产业升级迫在眉睫。

2009年,深圳总人口大约为900万人,其中本地户籍人口只有250万,伴随着区域转型和产业升级的变化及推出新的人口政策,2015年本地户籍人口已经接近400万,许多“候鸟”开始变为“家燕”。

(每答出一点给 2 分;如有其他答案,言之成理也可酌情给分) 6.①人物形象上,突出表现了颜大妈心明眼亮、知恩图报、豁达智慧的特点。
②情节上,呼应上文,解释了颜大妈不愿维护自已的知识产 老妈的关心。
③艺术效果上,这句话既道出了李有的善良,也显示了颜大妈的通情达理,小说借此赞美了彼此体贴的人间真情,具有很强的感染力。 (每答出一点给 2 分;如有其他答案,言之成理也可酌情给分) 7.A “世界上首台光量子计算机”有误,原文是“世界首台超越早期经典计算机的光量子计算机”。 8.C “性能已经在新闻发布会上得到证实”有误,原文只说是发布会介绍“进展情况”。 9.材料一:报道我国科学家在量子计算机方面取得的成就,以及对近期的展望;材料二:介绍量子计算机的相关知识和研发历史、进程; 材料三:报道外媒和国外学者对中国在量子计算机研究方面的关注。(每点 2 分,意思对即可) 10.B 四个“或”字起始的句子结构相同,均断在“或”前。“十四人”应断入前句,“请仍旧制”的主语为范百实禄。“余付之州县”和 “事多施行”为两个句子。原文标点为:“百禄察其中,或以恩泽市,或以瘝败收,或未历边方,或起于群盗,疏列其亡状者十四人,请仍旧制, 将佐颛教阅,余付之州县,事多施行。” 11.D 薨,古时称诸侯之死,大夫死曰卒。 12.A “最终说服了贾昌言”表述有误,文中有“百禄谕之不听”之言,最终是“本矍然,即檄止之”,而非说服。 13.(1)假使黄河改道而向北流,敌人才会有处于下游的忧虑,这是我们的优势。(北、下流各 1 分,判断句 1 分,句意 2 分。) (2)中原凭借信义安抚四夷,阿里骨没有过失,温溪心的虚实不能知晓,没有争端而出兵,这不是上策。(以、过、畔各 1 分,句意 2 分。) 译文: 范百禄字子功,进士及第,又应才识兼茂科考试。提点江东、利、梓路刑狱,加直集贤院。熊本治理泸蛮事务,有夷人首领无力抵抗请求投 降,副将贾昌言想杀了他来报功,范百禄劝阻他而不听,就前去对熊本说:“杀死投降的人不吉祥,救活一千人的人子孙受封。怎能容忍骄纵的 将领在境内横行不法?”熊本警觉起来,马上发公文制止。 七年,召知谏院。遇到旱灾,他请求处理当前的紧要事务,收回那些对百姓不利的法令,来救活那些将要死去的百姓。五路军队设置三十七 个将领,专门统率所在地的军队,甚至允许他们征用平民百姓参与军谋。范百禄了解其中实情,有的是用恩泽换取,有的是因为旷职败事被收留, 有的并未经历边事,有的是盗贼出身,就上疏陈奏其中不合要求的十四人,请求沿袭旧制,让武官专管教练检阅,其余的事交给州县,建议多被 采用施行。 都水王孝先建议把黄河引回故道,吕大防的意见倾向于此,命令范百禄前去视察。范百禄认为黄河向东流有一段是向高处流,而黄河的流势 是向下,不能引回,就赶快回京奏报这样做的原因,而且拿出神宗命令不要阻塞黄河故道的诏书一起呈上。吕大防仍然说:“黄河向东流,是中 原的阻隔。如今塘泺已经毁坏,界河淤积变浅,黄河要向北流了。”范百禄说:“塘泺有限制敌人之名,没有抵御敌人之实。假使黄河改道而向北 流,敌人才会有处于下游的忧虑,这是我们的优势。先帝诏书明文俱在,为什么擅自改变它呢?”于是此事才作罢。 以龙图阁学士担任开封府尹。他在百姓事务上勤勤恳恳,监狱中没有被关押的囚犯。属下想把监狱空的事情让报朝廷,范百禄说:“千里的 皇城,狱中没有一人,这是皇上的仁德,不是府尹的功劳。”没有答应。过了几个月,又担任翰林学士,任中书侍郎。 熙河范育说:“阿里骨残酷暴虐并且生病,温溪心八族都想归附,能够用计招纳。”范百禄说:“中原凭借信义安抚四夷,阿里骨没有过失, 温溪心的虚实不能知晓,没有争端而出兵,这不是上策。”范育又请求进筑纳迷等三城,范百禄说:“这都是良田,是必争之地,我筑了城,如果 敌人骑兵时常出动,我们如何耕作?以后即使想放弃它,花费已经很多,也无法办到。”皇帝都听从了他。 去世,享年六十五,追赠银青光禄大夫。 14.D “将军因为仰天大笑从马上摔下”错误,从“五色”“马前”很容易判断出这里是指野雉从空中落下,本诗要赞美将军的射技高超, 不可能会写其从马上摔下的。 15.①善于把握时机,虽然野雉时出时没,但是将军盘马弯弓,并不急着发射;②对射箭的距离和力度有把握,估计野雉飞起百馀尺,满弓 加箭;③射技精准,在百余尺的地方,“红翎”“白镞”交接,直中目标。(每点 2 分,意思对即可) 16.(1)入则无法家拂士 出则无敌国外患者 (2)固知一死生为虚诞 齐彭殇为妄作 (3)同是天涯沦落人 相逢何必曾相识 【解析】本题考查对名篇名句识记、正确默写能力。注意围绕题中所设情景答题。 (每空 1 分,出现错别字、漏字、添字现象,该空不得分) 17.D ①举世瞩目、万众瞩目。举世瞩目:全世界都关注。万众瞩目:大家十分关注。本处两个词语都可以。②一飞冲天、一鸣惊人。一 飞冲天:鸟儿展翅一飞,直冲云霄。比喻平时没有特殊表现,一下做出了惊人的成绩。一鸣惊人:比喻平时没有特殊的表现,一下子就有惊人的 成绩。此处用“一飞冲天”与前文搭配更恰当。③不在话下、不言而喻。不在话下:指事物轻微,不值得说,或事属当然,用不着说。此处不合 语境。不言而喻:不用说就可以明白。④未雨绸缪、防微杜渐。未雨绸缪:比喻事先做好准确。防微杜渐:在错误或坏事萌芽的时候及时制止, 不让它发展。此处不合语境。 18.C 原句存在很多毛病。一是搭配不当,“采取”与“标准”不搭配,二是成分残缺,“采取”缺少宾语中心语。正确表述为:在试采过 程中,按照国际环境管理体系、工艺安全风险管理等标准,采取了严格的环境保护措施。A.语序不当,应为“采取了严格的环境保护措施”。B. 搭配不当,“按照……目标”不能搭配。D.结构混乱,“工艺安全风险管理等标准”应作“按照”的宾语。

4.A(李部长原本没有“想通过明察暗访,了解被推荐的平小明的情况”,无中生有。) 5.①直接承题,交代清水河的基本情况。②点明清水河对清水河人的重要价值,更加突 出下文清水河水被污染问题的严重性。③自然地引出下面的乡长平小明,他被有的人说成跟 清水河的水一样清的清官。(每答对一点给 2 分) 6.①水虽然看上去是清的,却已被污染,说明不能只看事物的表面现象,要看到其实质; ②传言中平小明是个清官,而他做的事使他的“清官”名声受到怀疑;③选拔任用干部不能 只听传言,而要慎重调研,准确评价。(每答对一点给 2 分) 7.B 考查理解文中重要句子的能力和简单推理的能力。B 选项根据材料二,“时强时 弱,若隐若现,富于变化”指的是根据脉冲星振幅制作的音乐。 8.B 考查筛选并整合文中信息的能力。A 选项是对材料一第二、三段内容的概括分析, 正确;B 选项“实现了对天体物理学理论的巨大突破”错误,材料二原文说“FAST 超乎寻常 的表现一举实现了中国在脉冲星发现领域‘零的突破’”,可见 FAST 探测到脉冲星信号之前, 已经有了先例,并不是对有关理论的突破。C 项是对材料三第二段内容的分析,正确。D 项 是对材料三最后一段内容的分析,正确。理解时还要结合材料一第三段内容。 9.①材料一:“中国天眼”的落成启用对我国科研具有的重要意义,目的是凝聚中国创 新;②材料二:报道中国在探测脉冲星领域超乎寻常的发现;目的是展示“中国天眼”骄人 的成绩。③材料三:简要介绍“中国天眼”的核心要素和关键技术;目的是介绍“中国天眼” 的有关知识和建设意义。(每答对一点给 2 分) (考查筛选并整合文中信息、概括中心意思的能力,以及探究作品的主要观点和写作意 图的能力。解题时要注意选文各自的每个标题和主体内容。) 10.B “颉按禁地约束”是一分句,不可断开;“上其事”与“不报”是一件事情的两 个阶段,中间应断开;“开封府判官”为官名。原文标点为:“知益阳县,县接梅山溪峒,多 蛮獠出没,颉按禁地约束,召徭人耕垦,上其事,不报。累迁开封府判官、提点江西刑狱、 广东转运使。” 11.B 应为北宋神宗年号,下文有“哲宗立”之语。 12.B “与章惇不谋而合”表述有误,张颉的建议与章惇的作法大不相同。 13.(1)入朝见皇帝,皇帝首先说:“你以前说顺州不可守,确实是这样。”(觐、乡、 信各 1 分,句意 2 分。) (2)湖北溪徭叛乱,朝廷认为张颉素有威望,又改任荆南知府,刚到京城城门,突然 得病死去。(畔、知、暴各 1 分,句意 2 分。)

1.《史记·鲁世家》记载:鲁国从周公到顷公的三十四任君主中,第四任君主为第三任之弟,第六任为第五任之弟,其通过弑杀得以登上君位,第八任为第七任之弟,第十任为第九任之弟,第十八任为第十七任之弟。

其余皆为父死子继。

这表明当时鲁国A. 宗法制受到严重破坏B. 政治局势日趋动荡C. 注重缓和贵族间矛盾D. 出现违背宗法制的现象【答案】D【解析】【详解】材料中涉及到通过弑杀而登基和兄终弟及的现象,但不能说明宗法制遭到严重破坏,毕竟绝大部分君主是通过正常的“父死子继”登基的,因此只能说鲁国的发展历程中曾出现过违背宗法的现象,故D项正确,排除A项;政治局势日趋动荡,无法从题干中得到,题干并没有说因为弑杀而国家动荡不安,故B项错误;题干并没有涉及国君与贵族的矛盾,故C项错误。

大象天成大联考.全国名校联盟2017-2018学年高三适应性考试(五)文综答案

大象天成大联考·全国名校联盟2017-2018学年高三适应性考试(五)文科综合参考答案地理答案1~3.【知识定位】等温线判读、气候、冻土。

【能力目标】获取信息、解读信息,综合思维及地理实践力。

【解题思路】1.地温常年在0℃以下为永冻土,永冻土以上,地温在0℃上下波动,为季节性冻土。

读图可知,该地季节性冻土厚度约3米左右。

2.地表温度低于0℃的时间为河流结冰期,约7个月左右。

3.该地地表温度最高约12~13℃,最低约-14~-15℃,四个地区中,符合条件的只有青藏高原。

【正确答案】1.B2.C3.B4~6.【知识定位】坡地及太阳能资源的开发利用。

【能力目标】读图能力、综合思维及人地协调观。

【解题思路】4.张家口为山区,山地多,平地少,将太阳能电站建在山坡上,可以减少对农田占用,但起不到保护坡地的作用;由于地形复杂,仍然需要支架;从图上可以看出,电池板在山谷中也有分布,不是为了避免洪水和泥石流的破坏。

5.太阳能电池板为提高光能利用率,一般是黑色的,“绿色”是指太阳能为绿色能源,利用太阳能发电不会造成环境问题;太阳能电站需要占用土地,它不能促进山地绿化;电池板的生产和废弃后的处理都会有一定的环境影响,另一方面太阳能电站只是利用电池板发电,不是生产电池板。

6.太阳能电池板朝向太阳,发电效率最高,为了减少调节,一般正对正午太阳方向(在张家口朝南)安装,此电站电池板朝向随地形变化,各电池板发电峰值错开,有利于减小供电能力的时间差异。

【正确答案】4.B5.A6.D7~9.【知识定位】农业地域类型、农业区位因素、传统文化。

【能力目标】获取信息、解读信息,综合思维及地理实践力。

【解题思路】7.采用“套种”方式,可以使生长周期较长的农作物有足够的时间满足生长需要(前季作物可以推迟收割,后季作物可以提前播种或移栽),得以成熟,提高复种指数,实现熟制的改变。

如华北地区通过“套种”可以由“一年一熟”、“两年三熟”转变到“一年两熟”,甚至“一年多熟”。

天一大联考2019届高三第二次模拟考语文试卷含答案解析

天一大联考2019届高三第二次模拟考语文试卷含答案解析

天一大联考2019届高三第二次模拟考语文试卷一、现代文阅读(36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。

产生于公元前2世纪的礼记?乐记,以儒家思想为主,阿时吸救道家与法家思想,是出界最早的音乐美学论著,也是最早论述礼乐教化即美育的论著。

《乐记》及其礼乐教化理论,以“礼乐交融”为其东方特色,以“正声”“德青”为其艺さ求,以“天人合ー"为其文化理念,明显区別于西方的美育观念,彰显光彩照人的中国精神,这充分证明中华民族在文化艺术特别是美学与美育上的成熟与伟大,值得我们继承与发扬。

《礼记》记载,当年周公通过制礼作乐而治理国家、统一天下。

中国古代的“礼”起源于宗教祭祀之礼仪,发展为政治制度、道德行为规范和社会交往之人文礼仪等;“乐”是乐舞歌诗的总称。

礼乐教化是一种集政治治、道德与审美为一体的整体性教育,充分体現中国传统文化关联性的特点,相异予西方文化区分性的特点,强调发浑礼乐刑政文融互补的综合性治理作用。

礼乐教化还可以发特有的和合父子君臣族长乡里的团结教育作用,还有感染熏陶、移风易俗之用,所谓“乐也者,圣人之所乐也,而可以善民心”。

总之,礼乐教化在传统社会中充分发挥交融性与綜合性作用,是治国之重器。

《乐记)言:“乐者,伦理者也。

儒家学説认为乐与道德相通,乐音是人与禽兽的区别,而対整体音乐的理解则是君子与小人的区别。

礼乐教化之乐教包含乐德、乐语与乐舞等部分,所谓“乐德”指“中、和、祗、庸、孝、友”等德性的核心内涵,是乐教最重要的成分。

礼乐教化最重要的目的是弘扬德音与正声,抛弃溺乐与溺音。

《乐记》说:“圣人作为父子君臣,以为之纪纲。

纪纲既正,天下大定。

天下大定,然后正六律,和五声,弦歌(诗》《颂》,此之谓德音。

德音之谓乐。

”又说:“奸声乱色,不留聪明;淫乐恩礼,不接心术。

”这里将正声与德音提到“纪纲既正,天下大定’,’的政治高度,将奸声与淫乐视作扰乱思想与破坏心术的负面现象。
