通过良渚考古发掘，学者们普遍认为当时私有制已经产生，阶级分化日益明显，出现了权贵阶层。

以下能作为直接证据的考古发现是A．城中发现20多万公斤的炭化稻堆积B．少数墓葬有精美的玉器和陶器随葬C．古城遗址布局与山形水势充分契合D．碳14测定年代为公元前3000年左右2. 从甲骨文中我们可以看到很多商王求丰年和降雨的卜辞，但奇怪的是他们不是直接向他们心目中的最高神——“帝”请求，而是托祖先转达。

据此我们可以判定商代A. 祖先的地位高于神B. 国家大事完全通过占卜来决定C. 王权具有神秘色彩D. 崇拜祖先的宗法观念已经出现3. 《礼记·王制》规定：大诸侯国设三卿，都由天子任命，次一等的诸侯国也设三卿，其中 二卿由天子任命，一卿由国君任命，小诸侯国设有两卿，都由国君任命。

据此可知，西周 分封制A．保证了周天子的专制统治B．蕴含着中央集权的因素C．有效限制了地方诸侯权力 D．宗法血缘色彩极其淡薄4.《尚书大传》说：周公摄政，一年救乱，二年克殷，三年践奄，四年建侯卫，五年营成周，六年制作礼乐，七年致政成王。

对“四年建侯卫”“六年制作礼乐”解读正确的A. 建侯卫就是实行分封制，制作礼乐是为了维护宗法等级制B. 建侯卫就是实行郡国制，制作礼乐是为了维护郡国并行制C. 建侯卫就是推行宗法制，制作礼乐是为了用来代替分封制D. 建侯卫就是实行郡县制，制作礼乐是为了丰富周人的生活5. 春秋时期，大国打出“尊王”的旗帜争夺霸主地位，挟天子以号令其他诸侯；战国时期，诸侯不再尊崇周天子，自行称王并互相攻伐兼并。

这反映出A. 中央集权日趋瓦解B. 统一趋势逐渐增强C. 贵族政治已经崩溃D. 宗法体系受到冲击6. 下表是春秋战国时期从事政治活动的人中对出身所做的调查：这说明A．世卿世禄制度彻底消失 B．平民成为官员主要来源C．平民政治代替贵族政治 D．社会阶层流动趋于频繁7. 孔子曰：“苟有用我者，期月而已可也，三年有成.”孟子曰：“如欲乎治天下，当今之世，舍我其谁？”这反映当时的儒者A. 适应社会转型之努力B. 重构礼乐纲常的愿望C. 经世济民的担当精神D. 不受重用的愤懑之情8. 某学者评价“百家争鸣”时指出：“正是这一时期（战国时期）的政治混乱才迫使那些思想者不断反思社会的本质以及人民所应该承担的角色，一些人试图找到能够恢复政治和社会秩序的法则。

There was not one familiar face.I sighed and sat down to read my Economics.It was not long before the train was across the Causeway and in Malaysia.Johore Baru was just another city like Singapore,so I was tired of looking at the crowds of people as they hurried past.As we went beyond the city,I watched the straight rows of rubber trees and miles and miles of green.Then the first village came into sight. Immediately I came alive;I decided to wave back.From then on my journey became interesting.I threw my magazines into the waste basket and decided to join in Malaysian life.Then everything came alive.The mountains seemed to speak to me.Even the trees were smiling.I stared at everything a if I was looking at it for the first time.The day passed fast and I even forgot to have my lunch until I felt hungry.I looked at my watch and was surprised that it was 3:00 p.m. Soon the train pulled up at Butterworth.I looked at the people all around me.They all looked beautiful.When my uncle arrived with a smile,I threw my arms around him to give him a warm hug（拥抱）.I had never done this before.He seemed surprised and then his weather-beaten face warmed up with a huge smile.We walkedarm in arm to his car.I looked forward to the return journey.（1）The author expected the train trip to be______.A . adventurousB . pleasantC . dullD . exciting（2）What did the author remember most fondly of her train trip?A .

【详解】禽流感病毒无细胞结构，但有遗传物质；A正确；H5N1亚型病毒能引发传染病，必须寄生在活细胞内才能表现出生命的特征，B正确；病毒没有细胞结构，且缺少进行自主代谢的完整机制，因此只能寄生在活细胞中，但由于病毒具有生物的特征——繁殖后代，因此病毒是生物，C正确；H5N1型禽流感病毒，由蛋白质和核酸组成，没有细胞结构，只能在活细胞内生长繁殖，离不开活细胞，D错误。

【点睛】本题考查病毒的结构，要求考生识记病毒的结构，明确病毒没有细胞结构，其遗传物质是DNA或RNA，再准确判断各选项。

一、现代文阅读（39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。

如果说闻一多是新月派诗歌的元帅型人物，新月派的副帅就是徐志摩。

他们的主张虽然差不多，但写起诗来，他和闻一多相比还是有比较大的风格上的差异。

徐志摩跟闻一多相同的是他也喜欢讲点道理，讲点理论，向人炫耀他的学历。

但他那些文章看来看去，你总觉得他不一定是一个好学生，道理讲得比较差。

在新月派里，论理论修养他不如闻一多，不如梁实秋，这也未必就是缺点，他的性格就是不喜欢枯燥、繁琐的理论。

喜欢徐志摩诗歌的人一般以青少年为主，在中文系待着，二年级以上的人恐怕就没有喜欢徐志摩的了。

徐志摩的诗给人的感觉是更加依靠灵感，所以在当时被看成是天才诗人。

徐志摩的确是个天才，他自己也说，他写诗是靠灵魂深处来的一股暖意，这没法用道理来解释。

胡适有自己的诗歌理论，郭沫若有自己的诗歌理论，闻一多也有，但徐志摩所依靠的就是灵魂深处来的一股暖意。

其实徐志摩最好的诗不是《再别康桥》，比如他的《沙扬娜拉》写得更好。

这首诗非常短，不整齐，不押韵，好像不符合新月派的“三美”主张，但是你读起来有一种内在的整齐，内在的韵律，它的表达形式和它的表达对象完美地统一了。

另外有一首既整齐又自然的诗叫《雪花的快乐》，可以说既能代表徐志摩，也能代表新月派。

这首诗一共有四节，每一节的形式都一样，整齐和不整齐是搭配的。

这首诗每一节选的韵也是很见匠心的，潇洒的时候用的是花韵，飞扬的时候用的是比较明亮的韵，最后落到姑娘身上的时候变成消融，变成鼻音结尾。

这首诗几乎无可挑剔，能够代表徐志摩的艺术成就。

ATeenagers who spend hours in front of the television may have a poorer diet as young adults．A study，which involved nearly 1，400 high school students found those who watched TV for five hours or more every day had less healthy diets than other students five years later．Why does this happen？Should the parents take any measures？On the one hand，people who spend a lot of time in front of the TV，especially teenagers，may snack （吃零食）more，and that may influence their long-term diet quality．On the other hand，TV ads for fast food，sweets and snacks make teenagers eat more of those foods．TV time might also replace exercise time for some kids．The researchers found a clear relationship between TV time during high school and diet quality of the young．While the heaviest TV viewers were eating the most junk food，those who'd watched fewer than two hours every day had the most fruits and vegetables．As far as I am concerned，children should watch no more than two hours of television per day．And parents should set a good example by eating right，being physically active and curbing their own TV time．1. According to the passage，heavy TV viewers are easy to ______ ．A. eat more fruitsB. eat fewer vegetablesC.eat less junk foodD. eat more food high in calcium （钙）2. The underlined word "curbing" in the last paragraph can be replaced by ______ ．A. adding B. checking C. controlling D. stopping 3. What suggestion does the author give the parents？______ A. They must watch TV with their children．B. They should stop the children from watching TV．C. They should pay attention to nutrition in diets．D. They can't do what they don't want their children to do．BAn unusual trip to Hawaii brought two strangers closer and closer and their story deserves a wide spread.As her plane flew through the sky above the ocean, there came a sudden thunderstorm. Five minutes later, Uemoto and her copilot(副驾员驶) McMahon heard a strange sound. Then, without warning, they lost power to both of the engines. It took them a moment to process the fact that they might crash. The pilots powered through the items on the emergency checklist. Nothing worked. As the plane was falling, they jumped into the ocean.By ten that night, their bodies began trembling uncontrollably in the cool night air. Something must be done to pull them through. Swimming on her stomach, Uemoto had McMahon wrap his arms around her knees so he could rest his head on the back of her legs. To be with someone else and to feel another person's comforting presence in the darkness somehow made the suffering bearable.When the sun rose the next morning, they caught sight of the island of Hawaii, the destination they had dared dream! Suddenly, Uemoto saw a shark, which made her breath catch in her throat. "What do we do? What do we do?" Uemoto asked, frightened. "Just keep looking forward! If it comes close, I'll kick it in the eye!" said McMahon evenly. Unexpectedly, the shark circled them for about 30 minutes. Then, as quietly as it had appeared, it swam off. Uemoto and McMahon breathed a sigh of relief.After struggling in the water for over 20 hours, there came a US Navy helicopter. It flew overhead and next banked towards them. Uemoto and McMahon burst into tears. Alone, either of them would have died. But together, they made it.4. What caused the plane to crash?A. A sudden thunderstorm hit the plane.B. The engines of the plane broke down.C. The pilots operated the plane improperly.D. The emergency list failed to help the pilots.5. Which of the following best describes Uemoto and McMahon?A. pushy and humorous.B. Clear-headed and generous.C. Demanding and attractive.D. Strong-willed and considerate.6. What may be the best title of the passage?A. A Race against DeathB. A Test of FriendshipC. A Wonder Made by Joined HandsD. A Struggle Fought in the DarknessCHuman beings have used tools for a very long time. In some parts of the world you can still find tools that people used more than two million years ago. They made these tools by hitting one stone against another. In this way, they broke off pieces from one of the stones. These chips of stone were usually sharp on one side. People used them for cutting meat and skin from dead animals, and also for making other tools out of wood. Human beings needed to use tools because they did not have sharp teeth like other meat eating animals, such as lions and tigers. Tools helped people to get food more easily.Working with tools also helped to develop human intelligence. The human brain grew bigger, and human beings began to invent more and more tools and machines. The stone chip was one of the first tools that people used, and perhaps it is the most important. Some scientists say that it was the key to success of mankind.Since 1960 a new kind of tool has appeared. This is the silicon chip (硅芯片). It is smaller than a finger nail, but it can store lots of information. It is an electronic brain. Every year these chips get cleverer, but their size gets smaller, and their cost gets less. They are used in watches, calculators and intelligent machines that we can use in many ways. In the future we will not need to work with tools in the old way. Machines will do everything for us. People will have plenty of spare time. But what will they do with it?Human beings used stone chips for more than two million years, but human life changed very little in that time. We have used silicon chips for only a few years, but life is changing faster every day. What will life be like twenty years from now? What will the world be like two million years from now?7. From paragraph 1, we can know ________.A. why early human beings cut skin from dead animalsB. how early human beings discovered the toolsC. what early human beings used the tools forD. what food early human beings stored8. The stone chip is thought to be the most important tool because it ________.A. was very important to the development of mankindB. led to the invention of machines in the early timeC. developed cooking abilities of mankindD. was one of the first tools of mankind9. The silicon chip is mentioned in the passage to ________.A. show the changes of toolsB. introduce a new kind of toolC. give an example of using toolsD. compare the effects of two kinds of tools10. At the end of the passage the author seems to suggest that life in future is ________.A. out of orderB. less colorfulC. hard to predictD. full of meanings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。

2019届高三上学期测试（一）历史（考试时间：90分钟满分：100分）一、选择题（本大题共24小题，每小题2分共48分。

题中的四个选项只有一个符合题目要求。

）1.据《国语·鲁语上》记述，有虞氏和夏、商、周三族祭祀的时候，不仅上推到本族的先王、先公，还更进一步把本族来源与黄帝族系联系起来，都自认为是黄帝族的后裔。

这反映了当时的中国A. 已有民族认同的意识B. 区域间的文化交流频繁C. 政治制度具有连续性D. 农耕经济成为各朝根本【答案】A【解析】【详解】根据“有虞氏和夏、商、周三族祭祀的时候，不仅上推到本族的先王、先公，还更进一步把本族来源与黄帝族系联系起来”可以看出，有虞氏和夏、商、周三族已经形成拥有同一祖先，都是黄帝族后裔的认识，体现了已有民族认同的意识，故A正确；材料未体现区域间的文化交流频繁，故B错误；根据“有虞氏和夏、商、周三族祭祀的时候，不仅上推到本族的先王、先公，还更进一步把本族来源与黄帝族系联系起来”可知，材料强调的是拥有共同的先祖，体现的是民族认同，并未体现政治制度的连续性，故C错误；材料信息无法反映农耕经济成为社会根本，故D错误。

2.《我们的中国》一书中提出“西周的四合院”的研究视野，认为以西周为中心，东南西北被辐射地区相互交流，贵族通婚，形成了紧密的文化中心。

该观点A. 认为西周政治制度加强了中央集权B. 意在说明分封制标志中华民族形成C. 强调分封制之下存在着大一统因素D. 已经认识到分封制易造成地方割据【答案】C【解析】材料“以西周为中心，东南西北被辐射地区相互交流，贵族通婚，形成了紧密的文化中心”体现出分封制的影响，这反映出分封制在一定程度上可以促进大一统，故C项正确；西周时期没有实现中央集权，故A项错误；材料没有说明分封制对于民族关系影响，故B项错误；D 项与材料反映的正好相反，故排除。

点睛：“以西周为中心，东南西北被辐射地区相互交流，贵族通婚，形成了紧密的文化中心”是解题的关键信息，从中分析出分封制的作用。

理水（节选）鲁迅当两位大员回到京都的时候，别的考察员也大抵陆续回来了，只有禹还在外。

他们在家里休息了几天，水利局的同事们就在局里大排筵宴，替他们接风。

这一天真是车水马龙，不到黄昏时候，主客就全都到齐了，院子里却已经点起庭燎来，鼎中的牛肉香，一直透到门外虎贲的鼻子跟前，大家就一齐咽口水。

酒过三巡，大员们就讲了一些水乡沿途的风景，芦花似雪，泥水如金，黄鳝膏腴，青苔滑溜……等等。

微醺之后，才取出大家采集了来的民食来，都装着细巧的木匣子，盖上写着文字，有的是伏羲八卦体，有的是仓颉鬼哭体，大家就先来赏鉴这些字，争论得几乎打架之后，才决定以写着“国泰民安”的一块为第一，因为不但文字质朴难识，有上古淳厚之风，而且立言也很得体，可以宣付史馆的。

局外面也起了一阵喧嚷。

一群乞丐似的大汉，面目黧黑，衣服破旧，竟冲破了断绝交通的界线，闯到局里来了。

卫兵们大喝一声，连忙左右交叉了明晃晃的戈，挡住他们的去路。

“什么？——看明白！”当头是一条瘦长的莽汉，粗手粗脚的，怔了一下，大声说。

卫兵们在昏黄中定晴一看，就恭恭敬敬的立正，举戈，放他们进去了。

局里的大厅上发生了扰乱。

大家一望见一群莽汉们奔来，纷纷都想躲避，但看不见耀眼的兵器，就又硬着头皮，定晴去看。

头一个虽然面貌黑瘦，但从神情上，也就认识他正是禹；其余的自然是他的随员。

这一吓，把大家的酒意都吓退了，沙沙的一阵衣裳声，立刻都退在下面。

禹便一径跨到席上，并不屈膝而坐，却伸开了两脚，把大脚底对着大员们，又不穿袜子，满脚底都是栗子一般的老茧。

随员们就分坐在他的左右。

“大人是今天回京的？”一位大胆的属员，膝行而前了一点，恭敬的问。

“你们坐近一点来！”禹不答他的询问，只对大家说。
