2018-2019学年广东省普宁市华美实验学校高一上学期第二次月考(12月)英语试题

广东省普宁市华美实验学校高一上学期第二次月考语文试题阅读下面的文字，完成后面题目。

雾霾天气是一种重要的城市气象灾害。

大范围雾霾天气主要出现在冷空气较弱和水汽条件较好的大尺度大气环流形势下，近地面低空为静风或微风。

由于雾霾天气的湿度较高，水汽较大，雾滴提供了吸附和反应所需的场所，加速了反应性气态污染物向液态颗粒物成分的转化，同时颗粒物也容易作为凝结核加速雾霾的生成，两者相互作用，迅速形成污染。

随着冷空气来临，风速增强，雾霾逐渐消散。

研究表明，雾霾天气的形成和发展与气象条件关系密切。

一次持续性的雾霾天气过程往往具有显著阶段性特征，是一次持续时间长、阶段性特征明显的雾霾混合性天气。

持续性雾霾天气的第一阶段是霾阶段，该阶段PM2．5浓度增加显著，是能见度降低的主要原因；第二阶段是大雾阶段，该阶段迅速增大的相对湿度，是导致能见度下降的重要因素，在持续性大雾天气的静稳条件下，导致PM2．5浓度累积增加；第三阶段，由于北方冷空气的入侵，大雾天气结束。

可以看出，雾霾过程能见度的变化和相对湿度、PM2．5浓度、温度、风速的变化具有很好的阶段性对应关系。

相对湿度与能见度在整个过程中保持稳定的负相关线性关系。

由于温度决定了相对湿度的水平，因此温度与能见度的关系实际上反映了相对湿度与能见度的关系；而从整个过程来看，PM2．5与能见度是明显的非线性关系，在第一阶段PM2．5对能见度影响的速率要明显高于第二阶段，而在第二阶段中，PM2．5对能见度的影响水平几乎保持不变。

风速与能见度是正相关的线性关系，从整体上看，风速越大能见度越好，而从风速对能见度影响的线性趋势上看，第一阶段风速对能见度的影响速率要大于第二阶段风速对能见度的影响速率，第三阶段能见度随着风速的增加而迅速增大，反映出风速对雾霾过程能见度的转好有重要的作用。

以北京为例。

研究发现：无论是年均水平还是月均水平，霾日都要远远高于雾日，说明霾天气比雾天气对北京的影响更为严重。

高一语文第二次月考参考答案1.（3分）【C】（A“新气象”的表现有两种，一是许多诗人积极探索诗歌创新，二是好的诗歌也时而涌现，这两者不构成因果关系。

B前者陶醉其中，后者敬而远之，原因是多方面的，不能归结为两者的审美标准不一。

D原文是递进关系，不是因果关系。

）2.（3分）【B】(作者并没有认为新诗迅速衰落的原因是“三不到位”，“三不到位”只是“重要症结之一”而已。

此处曲解文意。

)3.（3分）【D】（“处理好诗歌的表达就能解决新诗的出路问题”错，除了语言之外，还有诸多关节。

）4. C5. ①孝顺。

如“我奶奶老是咳嗽，人家说吃蜂蜜管用呢，到底管不管？”“奶奶连吃了两天白萝卜拌蜂蜜，果然不咳嗽了，小焕子开心死了”。

②善良。

她对无法飞起的小蜜蜂充满怜惜，予以救治。

③真诚、淳朴。

如“小焕子说，拿着吧，人家说你少收我蜂蜜钱了”。

6. 不会更简洁。

①结构上，最后两段的内容更好地照应了题目“放蜂人”和前文放蜂人为生活奔波的情节，使结构完整。

②人物形象上，结尾由“笑”而“哭”的情节，使小女孩的形象更加丰满，不但孝顺、质朴，而且有这个年龄的女孩子特有的懵懂与多思。

③主题上，更好地传达了美与爱。

④效果上，引人遐想，增加了小说的韵味。

会更简洁。

理由：①情节上，至“小焕子就笑了”，故事已经很完整，加了后面的内容反而显得累赘。

②人物上，小焕子的性格已经得到充分刻画，形象已很丰满，没有必要继续写。

③主旨上，小说对普通人生活之难的同情与对人情美的提示已经写得很充分，无须再写。

④表达效果上，以“小焕了就笑了”结尾，能让人产生联想想象，颇有余味。

7.选B。

材料二中没有“消费者环保意识不强”信息。

8.选D。

A项错在因果解释有误；B项“餐饮企业忽视”解释有误；C项说法太片面，绝对。

9.需要政府职能部门制定行业标准并强制执行，并监管到位；分清责任主体，让相应的责任主体切实担负起处理外卖垃圾的责任；需要相关企业、平台积极承担经济和社会责任，开发和推广绿色餐具等；需要广大消费者养成良好环保意识和行为习惯10. A 根据上下文，这句话的含意是：邻居中有爱学习的青年都相随着来向他借书，每天借书达到几十卷，崔慰祖都亲自取出给他们，从来没有推托过。

2018-2019学年度第一学期第二次月考考试高一级英语试卷第一部分：阅读理解（共两节, 满分40分）第一节（共15小题；每小题2分, 满分30分）阅读下列短文, 从每篇短文后所给各题的四个选项(A、B、C和D)中, 选出最佳选项, 并在答题卡上将该项涂黑。

AJewel’s Online Footwear StoreLeather Dress ShoesPrice: $ 120.00Color: Black Leather Brown Leather Red Leather Natural LeatherAverage Rating: 3 out of 5 starsShipping Info: Standard: 7—10 business days Express: 3—5 daysCustomer ReviewsCustomer 1 ★★★★★My favorite shoes! I’ve been to many conferences where my business fellows have told me how much they like my shoes. Just wearing them makes me feel more calm and content in the office. I recommend them to all of my co-workers, and I own a pair of each color.Customer 2 ★These are the worst shoes I have ever worn! The leather came off after only one week, and everybody thought they were ugly. The bottom of the shoes made everything slippery. My employer fired me because he hated them! From then on, I will only wear Brand X shoes!Customer 3 ★★★These shoes do exactly what shoes are supposed to do. There isn’t anything too special about them. In the morning, I put them on and go about my day. They look delightful enough, and they are quite durable(耐用的). I will probably buy another pair.Customer 4 ★★★★These shoes are my most cherished possession. I met my bride while buying a pair of these shoes. She was the saleswoman at the store that I boughtthem at, and after she sold me three pairs, I asked her for her phone number and we started dating. Soon after that, we were engaged.

They make him attractive.C. He met his future wife while buying them.D. They make him feel more comfortable.BTelesforo sighed. He absolutely could not go to the new school one more day. The kids didn't laugh about his name, but they all played baseball and had lunch together without him. That was the whole problem. No one saw him or talked to him or even knew he was there.So when Telesforo went to school this morning, his head was bowed and his feet kicked at anything on the sidewalk.As usual, his teacher Mrs Benson read to the class from the newspaper, and today Telesforo was surprised when she read about the US Mint (铸币厂) making five special coins every year to honor each of the 50 states.He knew all about those shiny new state coins. He and his dad collected them. Dad gave him a small album to hold them. By the end of the year, Telesforo would have all 50. By the time he was ready for bed that night, he decided to take his coins to school tomorrow.The next day, when the kids settled, Telesforo opened his album and held it high for the class to see. “These are the coins Mrs Benson read ab out. And this is John Muir on the California coin，” he said, pointing. “Muir wanted to save the wilderness.” Telesforo spoke rapidly as he explained the designs: North Carolina and the first airplane flight. South Dakota, with four presidents carved on Mount Rushmore.“How can I get some of these coins? Why don't we meet after school？” Joshasked. “And Tel can explain everything we need to know.”Tel? Josh just called him Tel? Like they knew he existed? Like they were longtime friends? Telesforo held his album and smiled. So he did have friends.4．Why didn't Telesforo want to go to school at first?A．Because he wasn't good at playing baseball.B．Because his teacher didn't like him asking questions.C．Because his classmates were cold to him.D．Because his classmates laughed at him.5．From whom did Telesforo get the idea to make friends with his new classmates?A．His father.

At least it was back in 1992 when I traveled the country. Back then everyone seemed to be riding a bicycle. Millions of them, all black. Cars were rare. Yet since my arrival in Beijing last year, I've found the opposite is true. There are millions of cars. However, people still use their bicycles to get around. For many, it's the easiest and cheapest way to travel today. Bicycles also come in different colors—silver, green, red, blue, yellow, whatever you want.It's fun watching people biking. They rush quickly through crossroads, move skillfully through traffic, and ride even on sidewalks(人行道). Bicycles allow people the freedom to move about that cars just can't provide.Eager to be part of this aspect of Chinese culture, I decided to buy a bicycle.Great weather accompanied(陪伴) my great buy. I immediately jumped up on mybicycle seat and started home.My first ride home was orderly(守秩序的). To be safe, I stayed with a “pack”of bikers while cars on the streets came running swiftly out of nowhere at times. I didn't want to get hit. So I took the ride carefully. Crossing the streets was the biggest problem. It was a lot like crossing a major highway back in the United States. The streets here were wide, so crossing took time, skill and a little bit of luck.I finally made it home. The feeling on the bicycle was amazing. The airhitting my face and going through my hair was wonderful. I was sitting on top of the world as I passed by places and people. Biking made me feel alive.8. According to the author, why are bicycles still popular in China today?A. Because they are traditional and safe.B. Because they are convenient and not expensive.C. Because they are colorful and available.D. Because they are fast and environment friendly.9 The author decided to buy a bicycle because he intended _______.A. to ride it for funB. to use it for transportC. to experience local cultureD. to improve his riding skills10. How did the author feel about his street crossing?A. It was boring.B. It was difficult.C. It was lively.D. It was wonderful.11. Which of the following best describes the author's biking experience?A. The author enjoyed showing off his biking skills.B. The author was annoyed by the air while riding.C. The author was praised by the other bikers.D. The author took great pleasure in biking.DThe history of civil engineering (土木工程) is a very important story in the development of civilization (文明). Civil engineers began practising their profession four thousand years ago.What is left of their work is the proof that they were wise. These engineers of the ancient world built entire cities. They designed systems of pipes which supplied fresh water. They built water pipelines for farmlands as well as bridges of great length. Therelics of their buildings tell us much about the work of early engineers.Consider the pyramids(金字塔) of Egypt. They are evidence that some of the earliest engineers had great scientific ability. There is also evidence that those engineers could make lasting work of art and design. Although they lived thousands of years ago, the Egyptian engineers used very exact measurements. The base of the largest pyramid—the Great Pyramid near Giza—comes to within inches of being a perfect square. The pyramid is perfectly placed. Each corner points toward the exact directions of north, south, east and west. The inside of the pyramid is filled with complicated (复杂的) passages (通道). These lead to different rooms inside the pyramid. Many of these passages are of great length and height.The engineers of Egypt did more than design the pyramids. They also set up methods of moving and shaping the building materials. These materials were very heavy. They had to be brought from miles away and sometimes lifted several hundred feet. During the work the engineers commanded thousands of workers. The pyramids remain as evidence of the abilities of the ancient Egyptian engineers.12．The civil engineers of ancient times were wise enough to build entire cities, including ____ .A．systems of pipes, bridges and machineryB．pipeline systems, bridges and farmlandsC．water supply systems, bridges and pipelinesD．water supply systems, bridges and stadiums13. Which of the following is not true about the Great Pyramid of Egypt?A. It was exactly measured.B. It is near Giza.C. Its base is a square.D. It has rooms of great height. 14．From the passage we know that ________ .A．building materials were broken into small piecesB．there were no requirements for the size and shape of building materialsC．Egyptian engineers were not concerned with the size and shape of building materialsD．building materials were processed (加工) to meet certain requirements15. What is the purpose of this text?A. To introduce to us how the pyramids of Egypt was built.B. To tell us how to move materials in the ancient times.C. To show that the ancient engineers made great contributions in the development of civilization.D. To introduce some great works in the ancient times.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。

That means the average(平均的) farm income was about 71,000 dollars, or a gain of about three percent from the year before.However, the growth in earnings depended on the size of the farm. Large farms had increased earnings of six and one-half percent. Smaller farms saw growth in earnings of less than three percent.Part of American farm income came from the federal (联邦的) government. The Department of Agriculture reports that about thirty-nine percent of farmers accepted some kind of aid(援助), or subsidy(津贴) in 2017. Reports say the total amount of farm aid paid last year is estimated at 15,700 million dollars.An organization called the Environmental Working Group keeps information on all farm subsidies paid by the government. The group examined subsidies between 2008 and 2017.It says ten percent of farms received seventy-two percent of government subsidies during that nine-year period. The group says big farms that are organized as corporations (公司) or partnership businesses receive the most aid. It says the big farms receive more aid, even when they are more profitable(盈利的) than smaller family farms.Critics(评论家) say farm subsidies are costly and wasteful. Critics also note that subsidies go only to growers of widely traded crops, like corn, cotton, wheat and soybean.But many farmers, including the ones who only receive a few thousand dollars a year, support the subsidy programs. They say small farming communities in states like Minnesota, Nebraska, and South Dakota would not survive without the aid.8. What is the probable number of American farms?A. 10 million.B. 1 million.C. 10 thousand.D. 100 thousand.9. Why was 2018 a good year for American farmers?A. American farmers’ earnings increased a lot in 2018.B. The federal government gave American farmers more aid in 2018.C. Big farms were organized as partnership businesses in 2018.D. The federal government reduced farmers’ taxes in 2018.10. Which of the following statements is TRUE according to the passage?A. Small farms will get more government aid.B. Only big farms can get the government aid.C. Only profitable farms can get the government aid.D. Farmers growing crops like corn and cotton may get the government aid easily.11. What attitude do critics hold towards the farm subsidies?A. supportiveB. indifferentC. againstD. objectiveDWhat is it that makes people laugh? More than two thousand years ago the ancient Greek philosopher Aristotle defined (定义) jokes as the pleasure that results from a feeling of victory by showing we’re better than someone else in a certain way. According to Aristotle and many other philosophers，all jokes depend mainly on showing inferiority in another person or group of persons — that is，putting it clearly，on showing that they are worse off than ourselves. Jokes raise our good opinion of ourselves at someone else’s expense.Showing how much better than other people is only one reason we like jokes. Someone may also use a joke to express their anger or their cruelty or any other kind of action that is not acceptable to us. We feel free to laugh when we hear about someone sliding on a banana skin. The joke lets us express those attitudes which are usually unacceptable to society. This is probably the reason why some of the jokes，especially those involving cruelty，are so popular with certain people.Besides，all jokes depend on our enjoyment of laughing at something that is strange and out of place because it’s different from things which are happening around it. The same situation can be either sad or pleasant，depending entirely on how strange and out of place it is. A good joke-teller will always try to build up a situation in which one thing is expected until something unexpected suddenly happens，and so we laugh.12. According to Aristotle, all jokes depend mainly on ______.A. making people laugh unexpectedlyB. resulting in a sense of successC. having a good opinion of other peopleD. showing inferiority in another person or group13. The underlined word “inferiority” (in Paragraph 1) means ______.A. something that is unexpectedB. something that is unusualC. something that is not as good as something elseD. something that is better than something else14. What’s the main idea of Paragraph 2?A. Showing we are better than other people is the only one reason we like jokes.B. When people are angry, they would like to hear jokes.C. People who like jokes are usually cruel.D. To express those attitudes usually unacceptable to society is one of the reasonswe like jokes.15. What will a good joke-teller always try to do?A. Make a sad situation into a pleasant one.B. Make different things happen at the same time.C. Make an unexpected thing happen in an expected situation.D. Make people laugh at something unusual and out of place.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。

广东省普宁市华丽实验学校2018-2019 学年高一语文放学期第二次月考试题一、现代文阅读（共36 分）（一）阐述类文本阅读（本题共 3 小题， 9 分）阅读下边的文字，达成1--3 题。

在几千年的中华文明史中，我国保留了大批的纸质文件文籍。

中国作为四大文明的起源地之一。

同时也是古代文件珍藏的大国，一直以人文荟萃、文籍浩瀚著称于世。

全国各级公共图书室、博物馆以及教育、宗教、民族、文物等系统均有数目不等的古籍珍藏，是货真价实的历史文件大国。

党的十九大报告指出，“文化是一个国家、一个民族的灵魂。

文化兴国运兴，文化强民族强”。

文化是民族之魂，有超越时空的稳固性与凝集力。

对中华优异传统文化的深沉认可，正是今日及将来我国文化工作的精神支撑与理论基础之一。

互联网时代，任何一个国家都一定面对文化多样性与全世界化的挑战，中华文籍作为中华民族的文化基础，其意义则显得更加重要。

党的十九大把中国特点社会主义文化与文化自信写入党章，这是对中国特点社会主义内涵的崭新拓展和深入，是对文化战略地位的崭新认识和升华。

我们应当意识到，“今世中国文化固然有现代文化要素和外来文化要素，却离不开中国文化传统这一根本和本源”。

中华优异传统文化是中国特征的重要构成部分，是我们坚定文化自信的重要基础与本源。

早已有学者发现，马克思主义之所以能够在中国生根抽芽，并不是有时，中华优异传统文化与马克思主义有着很多共通之处。

倒如，梁漱溟先生谈到：“无产阶级精神既有高于我们风俗之处，同时又和我们的固有精神初不相远，中国人很简单学得来。

”古代中国“理性早启，文化早熟“，中国文化着重人与人之间的情理，这使得中华文化有别于西方文化的“工具理性”。

换言之，中华优异传统文化一向重视人与人的关系，这与资本主义社会重视人与物的关系截然相反，但与马克思主义却有必定的相容性与一致性。

今日，我们谈及文化自信，就是希望成立一种“超越民族国家博彝争夺理念的规则与价值”，这是一种我们在实践中探究出来的文化发展方向。

The more you sit each day, the more chance you have of getting sick.Richard Rosenkranz of Kansas State University was among the researchers. He said people who sat for long periods were at great risk of diseases when compared with those who sat less. He said that was especially true for some chronic (慢性的) diseases.Richard Rosenkranz studied the relationship between sitting and chronic diseases in middle-aged Australian men. He worked with researchers from the University of Western Sydney. They examined the health records of more than 63,000 men from NewSouth Wales. The men were between the ages of 45 and 65. The men reported about what diseases they had, or did not have. And they kept record of the amount of time each day that they sat.The study also showed that exercising every morning for 30 minutes did not reduce the health risk if you spend the next eight hours sitting at the desk. Mr. Rosenkranz said it was important to make sure you exercise. But he said it was also important to find ways not to sit so much during the day.Many jobs today require sitting and working at the desk all day. James Levine works at the Mayo Clinic in the United Sates. He suggests working while standing at high table some of the time instead of sitting at a desk. Dr. Levine also suggests standing while using the telephone or eating. Or he advises walking with the people you work with for an on-foot meeting. And he notes that if you spend more time on your feet, you may have muscle activity that helps burn fats and sugars in your body.4. The underlined sentence in the first paragraph implies that ________.A. doctors should treat all the patients wellB. doctors should make use of every methodC. one should value his health before he loses itD. one should depend on himself to keep healthy5. How did Richard Rosenkranz make the study?A. By examining some records and reports.B. By making some laboratory experiments.C. By talking with the doctors and patients.D. By watching the men’s daily performance.6. According to Dr. Levine, in order to avoid the harm of long-time sitting, one should ________.A. exercise more oftenB. change his jobC. stay away from the deskD. stand or walk more7. what’s the passage mainly about?A.people who sit down often are at a higher risk of being attacked by serious illnesses.B. People who sit longer daily have more chance of falling ill.C. people who do exercises regularly are less likely to get sick.D. People who exercise every morning for 30minutes will not reduce the health risk.CEric and Doris King Turner are packing their bags for New Zealand. They're busy deciding what to pack and what to leave behind in Britain and are making plans to extend their new home in Nelson. Doris is looking forward to getting the garden into shape and Eric has his heart set on a spot of fly fishing. The difference is that Eric is 102, Doris is 87. Eric thinks he's Britain's oldest emigrant.In January next year Eric King Turner and his wife of 12 years will wave goodbyeto their neighbors, and set sail from Southampton on the voyage of a lifetime. The ocean liner (远洋客轮)Saga Rose will take six weeks to get to Auckland and the coupleare expecting a red-carpet welcome from family.Doris was born in New Zealand but gave up her homeland when the couple met and married in the late 1990s. But New Zealand is close to both their hearts and the attraction of family and friends, and the good fishing helped to persuade them to move.Doris, who has five children and nine grandchildren, supported her husband's application to settle in New Zealand. The paperwork took five months. Eric says, "Wenot only had to produce a marriage certificate but we had to produce evidence thatwe were in a long and stable relationship!" He also said he was not asked about hisage but had to show that he could support himself financially in New Zealand."I like New Zealand. The way of life is very much the same as it is here but itis not so crowded." His wife has always been “a little bit homesick〞 but has never complained. Now the couple are in the middle of the task of sorting out possessionsand selling their flat.8. Which of the following statements is TRUE according to the passage?A．They decided to leave all the things behind in Britain.B．The wife always complained about the life in Britain.C．The couple will set up their new home in Nelson.D．Doris and Eric will go to New Zealand to hold the wedding.9.

What’s the old couple’s attitude towards living in New Zealand?A. Disappointed.B. Satisfied.C. Horrified.D.Surprised.DWhen I was nine years old, I loved to go fishing with my dad. But the only thing that wasn’t very fun about it was that he could catch many fish while I couldn’t catch anything. I usually got pretty upset and kept asking him why. He always answered, “Son, if you want to catch a fish, you have to think like a fish.〞 I remember being even more upset then because, “I’m not a fish!〞I didn’t know how to think like a fish. Besides, I reasoned, how could what I think influence what a fish does?As I got a little older I began to understand what my dad really meant. So, I read some books on fish. And I even joined the local fishing club and started attending the monthly meetings. I learned that a fish is a cold-blooded animal and therefore is very sensitive to water temperature. That is why fish prefer shallow water to deep water because the former is warmer. Besides, water is usually warmer in direct sunlight than in the shade. Yet, fish don’t have any eyelids (眼皮) and the sun hurts their eyes. The more I understood fish, the more I became effective at finding and catching them.When I grew up and entered the business world, I remember hearing my first boss say, “We all need t o think like sales people. 〞But it didn’t completely make sense. My dad never once said, “If you want to catch a fish you need to think like a fisherman.〞What he said was, “You need to think like a fish.〞 Years later, withgreat efforts to promote long-term services to people much older and richer than me,I gradually learned what we all need is to think more like customers. It is not aneasy job. I will show you how in the following chapters(章节).12. Why was the author upset in fishing trips when he was nine?A. He could not catch a fish.B. His father was not patient with him.C. His father did not teach him fishing.D. He could not influence a fish as hisfather did.13. According to the author, fish are most likely to be found _ .A. in deep water on sunny daysB. in deep water on cloudy daysC. in shallow water under sunlightD. in shallow water under waterside trees14. After entering the business world, the author found .A. it easy to think like a customerB. hi s first boss’s sales ideasreasonableC. his father’s fishing advice inspiringD. it difficult to sell services to poorpeople15. This passage most likely comes from .A. a book about salesB.a fishing guideC. a novel on childhoodD. a millionaire’s story第二节〔共5小题；每题2分，总分值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正确选项。
