2016-2017学年辽宁省抚顺市高一(下)期末英语试卷
2016-2017学年辽宁省抚顺市高一（下）期末英语试卷第一部分阅读理解（共两节）第1节（满分30分）阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该项涂黑．3．（6分）I bought a jasmine（茉莉）plant for my office．When I bought it，I was told it would bloom（开花）and the sweet smell would fill my office．I had the plant for two months，and every day I looked at it，but there weren't any flowers or pleasant smell．I was not happy，so I gave the plant to my friend Linda．One day，another friend Mary called and invited me to her office．When I walked in，her jasmine flowers surprised me．I reached out to touch the flowers．Mary cut some and gave them to me．I couldn't help smelling them．Surrounded by the sweet smell of only a handful of these flowers，I suddenly understood something．Mary bought her plant the same time I did．It took a year for her jasmine to bloom．I was so impatient for mine to bloom；regretfully，I gave it away．In a way my life is like the jasmine plant．I need to be patient and let things happen．Last Sunday Linda told me that she was going abroad the next week．Before she left，she returned the plant to me．This time I am going to wait．I have learned that when we want something in our life，we have to be patient．I am slowly learning to have that patience to wait for my jasmine to bloom．21．Before she gave the jasmine away，the writer had it for．A．one dayB．two weeksC．two monthsD．one year22．When the writer saw Mary's jasmine，she felt．A．unhappyB．astonishedC．hopefulD．peaceful23．What has the writer learned from her experience？A．Flowers can make life better．B．Patience is needed in life．C．Friendship is necessary for us．D．Jasmine can be a wonderful plant．4．（8分）Will it matter if you don't take your breakfast？Recently a test was given in the United States．Those tested included people of different ages，from 12 to 83．During the experiment，these people were given all kinds of breakfasts，and sometimes they got no breakfast at all．Special tests were set up to see how well their bodies worked when they had eaten a certain kind of breakfast．The results show that if a person eats a proper breakfast，he or she will work with better effect than if he or she has no breakfast．This fact appears to be especially true if a person works with his brains．If a student eats fruit，eggs，bread and milk before going to school，he will learn more quickly and listen with more attention to class．Opposite to what many people believe，if you don't eat breakfast，you will not lose weight．This is because people become so hungry at noon that they eat too much for lunch，and end up gaining weight instead of losing．You will probably lose more weight if you reduce your other meals．24．During the test，those who were tested were given．A．different breakfast or noneB．very rich breakfastC．little food for breakfastD．no breakfast at all25．According to the passage，if a student does not eat breakfast，．A．he will fall illB．his mind will work more slowlyC．he will not make progress in his studyD．he will fail to listen to his teacher26．The passage mentions that many people believe that if you don't eat breakfast，you will．A．be healthierB．not lose weightC．lose weightD．gain a lot of weight27．Which of the following is not true according to the passage？A．Poor breakfasts affect those who work with brains．B．Morning diet may cause one to get fatter．C．Eating less in lunch and supper may help to lose weight．D．Reducing lunch and supper is of less value in weight losing．5．（8分）The Best of AlaskaNothing evokes（唤起）Alaska like a whale exploding out of the water or an eagle pulling a silver fish from the river．Combine these images with high mountains，brilliant icebergs and wonderful meals and you really do have the best of Alaska!Join us for an unforgettable 7﹣day excursion（远足）to the last frontier!Highlights：Juneau：Juneau，the state capital，is rich in culture and scenic beauty．It is here that we start and end our trip．Haines：Haines is a small community located along the fjords（海湾）．The natural beauty and expansive wilderness found here have made Haines a premier center for adventure in Alaska．Alaska Indian Arts：Alaska Indian Arts is a nonprofit corporation dedicated to the preservation and continuation of traditional native craft and culture of the Northwest Native Tribes．We spend a few hours learning carving，native beading and culture from these master artists．Skagway：Skagway is a lively town，which still reflects its gold rush roots and contains colorful shops．In Skagway，we stop by the Klondike Gold Rush National Park Visitor's Center and ride the White Pass Yukon Route Railway．Gustavus：Gustavus is the gateway to the Glacier Bay National Park．We'll stay at a comfortable lodge（旅馆）here for two nights．This will be the base for both the whale﹣watching excursion and a full day cruise（乘船游览）in Glacier Bay．Dates/Prices：2012：May 16，June 20，July 18，and August 15．7days﹣﹩3，500，including lodging，all meals，excursions，guides，park fees，sales taxes，and transportation between Juneau，Skagway，Haines，and Gustavus．Not included：alcohol，personal items，airfare to and from Juneau．Contact：E﹣mail：info@alaskamountainguides．comTelephone：800﹣766﹣3396Address：Alaska Mountain Guides & Climbing School，P．O．Box 1081，Haines AK 9982728．You can feel the history of the local place at．A．JuneauB．HainesC．SkagwayD．Gustavus29．Which of the following is a tourist required to pay additional fees （费用）？A．Flying from Juneau to his hometownB．A full day cruise in Glacier Bay．C．Having the last supper at JuneauD．Going from Gustavus to Juneau by train．30．According to the advertisement，the tourists of the excursion．A．will spend one day experiencing the local culture at Alaska Indian Arts．B．the cost of the 7﹣day excursion is￥3，500C．are able to experience some adventurous activities in JuneauD．can contact Alaska Mountain Guides & Climbing School by e﹣mail，calling or letter31．It is known from the advisement that．A．Alaska is famous for its culture，history and natural beautyB．Juneau，as the state capital，is much more beautiful than HainesC．Skagway was the richest town of Alaska in the pastD．the native culture of the Northwest Native Tribes is dying out．6．（8分）Actually we have known a lot of examples and meaningful words to support the fact that we should try our best to ease the bad impression of others．Just like the old saying goes，we should give a better assumption（假设；承担）to the one than we think he was．But many of us always fail to do this．Take the situation of my class for example．Right at the beginning of the first term when we were freshmen we all showed great favor to each other．And when there was an activity that needed some people to join，we would be willing to attend whether it was interesting or not．And we were really like brothers and sisters，and our class was just like a family，a warm family．But now，I feel tired of those meaningless activities not only because of the boring activities themselves but also the cool response of our classmates．I think the reasons why the passion （激情）of most classmates is so low may be as follows：To start with，many of us take part in more than one organization，which will certainly make us tired．Also，in the study fields，many of us may find that our courses are sometimes difficult to understand or comprehend，especially the specialized subjects．Moreover，"history"teaches us that if one does not study hard，it is possible to fail in the exams．So it is a big and good excuse to say that"I do really want to attend，but I have a lot of homework to do，so…"Last but not least，some people believe that some of our leaders should not beregarded as a leader；maybe I should say we，as leaders，lost the reputation，support and trust of yours．At least I am the warm﹣hearted one，although I cannot promise you that your advice will be adopted （采纳）surely，at least I will spare no effort to"give"you the right to be heard，and to serve you．Be active to show your talents and abilities and to create a better image of our class．Most important of all，work painstakingly for a better condition that we should have reached．32．Which of the following statements is TRUE？A．Students were too busy to take part in activities after their classes．B．Students'passion for activities grew gradually because they were interesting．C．Students'passion for activities was high at first but disappeared gradually．D．Students were unwilling to participate in activities because of their leaders．33．Which can replace the underlined word excuse in the Paragraph 5？A．reasonB．intelligenceC．measureD．curiosity34．We can infer from the passage that the writer must be．A．a devoted class leaderB．a responsible teacherC．a top student in classD．a supporter of activities35．The writer hopes that all the members of the class will．A．develop better talents and skillsB．improve their abilities and creativityC．follow others'advice patientlyD．work together to make a better class．第二节（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．选项中有两项为多余选项．7．（10分）Life is just like a box．Inside it are happiness and sorrow，failure and success，hope and despair （绝望）．Life is a learning process．Experiences in it teach us new lessons and make us a better person．LoveLove plays a key role in our life．Love makes you feel wanted．Without love a person could become cruel and violent．In the early stage of our life，our parents are the ones who show us with unconditional love and care．（36）．But we always tend to take this for granted．It is only after marriage and having kids that a person understands and becomes sensitive to the feelings of others．Kids make a person responsible and mature and help us to understand life better．Happiness and SorrowMaterialistic（贪图享乐的）happiness is short﹣lived，but happiness achieved by bringing a smile on others gives a certain level of fulfillment （实现，满足）．（37）．No mind is happy without peace．We realize the true worth of happiness when we are in sorrow．Sorrow is basically due to death of a loved one，failure and despair．But these things are temporary and pass away．Failure and Success（38）．It helps us to touch the sky，teaches us to survive and shows us a specific way．Hope and DespairHope is what keeps life going．Parents always hope their children will do well．Hope makes us dream．Hope builds in patience．（39），because after every night there is a day．Nothing remains the same．We have only one choice﹣keep moving on in life and be hopeful．Life teaches us not to regret over yesterday，for it has passed and is beyond our control．Tomorrow is unknown，for it could either be bright or dull．（40），so that we will enjoy a better tomorrow．A．So let's enjoy every dayB．Life teaches us not to despair even in the darkest hourC．They tell us what is right or wrong，good or bad．D．Success lies in trusting yourselfE．So what we can choose is to work hard todayF．Peace of mind is the main link to happinessG．Failure is the path to success．第二部分完形填空（每小题1.5分，满分30分）阅读下面短文，从短文后各题所给的四个选项（A、B、C和D）中，选出可以填入空白处的最佳选项，并在答题卡上将该项涂黑．8．（30分）I learned how to accept life as it is from my father．（41），he didn't teach me acceptance when he was strong and healthy，but rather when he was （42）and ill．My father was（43） a strong man who loved being active，but a terrible illness（44）all that away．Now he can no longer walk，and he must sit quietly in a chair all day．Even talking is （45）．One night，I went to visit him with my sisters．We started （46）about life，and I told them about one of my （47）．I said that we must very often give things up （48）we grow﹣﹣﹣our health，our beauty，our friends﹣﹣﹣but it always （49）that after we give something up，we gain something new in its place．Then suddenly my father （50）up．He said，"But，Peter，I gave up （51）!What did I gain？"I thought and thought，but I couldn't think of anything to say．（52），he answered his own question，"I （53）the love of my family．"I looked at my sisters and saw tears in their eyes，along with hope and thankfulness．I was also （54）by his words．After that，when I began to feel angry at someone，I

bloom（开花）and the sweet smell would fill my office．I had the plant for two months，and every day I looked at it，but there weren't any flowers or pleasant smell．I was not happy，so I gave the plant to my friend Linda．One day，another friend Mary called and invited me to her office．When I walked in，her jasmine flowers surprised me．I reached out to touch the flowers．Mary cut some and gave them to me．I couldn't help smelling them．Surrounded by the sweet smell of only a handful of these flowers，I suddenly understood something．Mary bought her plant the same time I did．It took a year for her jasmine to bloom．I was so impatient for mine to bloom；regretfully，I gave it away．In a way my life is like the jasmine plant．I need to be patient and let things happen．Last Sunday Linda told me that she was going abroad the next week．Before she left，she returned the plant to me．This time I am going to wait．I have learned that when we want something in our life，we have to be patient．I am slowly learning to have that patience to wait for my jasmine to bloom．21．Before she gave the jasmine away，the writer had it for C．A．one dayB．two weeksC．two monthsD．one year22．When the writer saw Mary's jasmine，she felt B．A．unhappyB．astonishedC．hopefulD．peaceful23．What has the writer learned from her experience？BA．Flowers can make life better．B．Patience is needed in life．C．Friendship is necessary for us．D．Jasmine can

Linda．我保存茉莉花两个月，每天都会看它，但是没有开花，也没有香味，我很不开心，所以把它送给了我的朋友Linda．由此可知答案为C．22．B．细节理解题．根据文章第二段When I walked in，her jasmine flowers surprised me，当我走进Mary的办公室，她的茉莉花让我很吃惊．故选B．23．B．主旨大意题．文中最后一段I have learned that when we want something in our life，we have to be patient可知作者通过他养茉莉花这样一件事想告诉我们，生活中无论做什么事都要有耐心，答案为B．4．（8分）Will it matter if you don't take your breakfast？Recently a test was given in the United States．Those tested included people of different ages，from 12 to 83．During the experiment，these people were given all kinds of breakfasts，and sometimes they got no breakfast at all．Special tests were set up to see how well their bodies worked when they had eaten a certain kind of breakfast．The results show that if a person eats a proper breakfast，he or she will work with better effect than if he or she has no breakfast．This fact appears to be especially true if a person works with his brains．If a student eats fruit，eggs，bread and milk before going to school，he will learn more quickly and listen with more attention to class．Opposite to what many people believe，if you don't eat breakfast，you will not loseweight．This is because people become so hungry at noon that they eat too much for lunch，and end up gaining weight instead of losing．You will probably lose more weight if you reduce your other meals．24．During the test，those who were tested were given A．A．different breakfast or noneB．very rich breakfastC．little food for breakfastD．no breakfast at all25．According to the passage，if a student does not eat breakfast，B．A．he will fall illB．his mind will work more slowlyC．he will

weightD．gain a lot of weight27．Which of the following is not true according to the passage？DA．Poor breakfasts affect those who work with brains．B．Morning diet may cause one to get fatter．C．Eating less in lunch and supper may help to lose weight．D．Reducing lunch and supper is of less value in weight losing．【解答】24﹣27 ABCD24．A细节理解题．根据"these people were given all kinds of breakfasts，and sometimes they got no breakfast at all"可知过程中对于不同的早餐或者不吃早餐进行了测试．故选A．25．B推理判断题．根据"If a student eats fruit，eggs，bread and milk before going to school，he will learn more quickly and listen with more attention to class"可知，如果一个学生吃了有营养的早餐再去上学，将会学习更快注意力更集中，可以推测出学生如果不吃早饭大脑运转力将会变慢．故选B．26．C推理判断题．根据"Opposite to what many people believe，if you don't eat breakfast，you will not lose weight"说明很多人原来以为不吃早饭可以减肥，实际上比吃早饭更不能达到减肥的目的．故选C．27．D推理判断题．根据"You will probably lose more weight if you reduce your other meals"说明不吃早饭不会让人减肥，但是不吃中饭和晚饭却可以让人减肥．故选D．5．（8分）The Best of AlaskaNothing

细节理解题．根据日期/价格介绍中的"Not included：alcohol，personal items，airfare to and from Juneau．"可知，旅游费用不包含从Juneau往返各地的机票钱．所以答案选A．30．D 推理判断题．根据HIGHLIGHTS中对Haines的介绍，"The natural beauty and expansive wilderness found here have made Haines a premier center for adventure in Alaska．"这里的自然美景和广阔的荒野使海恩斯成为阿拉斯加首屈一指的探险中心．所以答案选D．31．A 推理判断题．根据"Highlights"介绍的几处景点可知，它们要么以当地历史或文化，要么以当地自然景观而出名．由此不难推断，阿拉斯加州以其历史、文化和自然景观出名．所以答案选A．6．（8分）Actually we have known a lot of examples and meaningful words to support the fact that we should try our best to ease the bad impression of others．Just like the old saying goes，we should give a better assumption（假设；承担）to the one than we think he was．But many of us always fail to do this．Take the situation of my class for example．Right at the beginning of the first term when we were freshmen we all showed great favor to each other．And when there was an activity that needed some people to join，we would be willing to attendwhether it was interesting or not．And we were really like brothers and sisters，and our class was just like a family，a warm family．But now，I feel tired of those meaningless activities not only because of the boring activities themselves but also the cool response of our classmates．I think the reasons why the passion （激情）of most classmates is so low may be as follows：To start with，many of us take part in more than one organization，which will certainly make us tired．Also，in the study fields，many of us may find that our courses are sometimes difficult to understand or comprehend，especially the specialized subjects．Moreover，"history"teaches us that if one does not study hard，it is possible to fail in the exams．So it is a big and good excuse to say that"I do really want to attend，but I have a lot of homework to do，so…"Last but not least，some people believe that some of our leaders should not be regarded as a leader；maybe I should say we，as leaders，lost the reputation，support and trust of yours．At least I am the warm﹣hearted one，although I cannot promise you that your advice will be adopted （采纳）surely，at least I will spare no effort to"give"you the right to be heard，and to serve you．Be active to show your talents and abilities and to create a better image of our class．Most important of all，work painstakingly for a better condition that we should have reached．32．Which of the following statements is TRUE？CA．Students were too busy to take part in activities after their classes．B．Students'passion for activities grew

leaderB．a responsible teacherC．a top student in classD．a supporter of activities35．The writer hopes that all the members of the class will D．A．develop better talents and skillsB．improve their abilities and creativityC．follow others'advice patientlyD．work together to make a better class．【解答】32．C．细节理解题．根据第二段But now，I feel tired of those meaningless activities not only because of the boring activities themselves but also the cool response of our classmates可知学生对于活动的乐趣开始很高但逐渐变得低；故选C．33．A．词义猜测题．根据文章But now，I feel tired of those meaningless activities not only because of the boring activities themselves but also the cool response of our classmates可知所以说"我真的很想参加，但是我有很多作业要做，所以…"是一个很好的借口；意为原因；故选A．34．A．推理判断题．根据文章Last but not least，some people believe that some of our leaders should not be regarded as a leader；maybe I should say we，as leaders，lost the reputation，support and trust of yours可知作者是一个班长；故选A．35．D．细节理解题．根据文章Be active to show your talents and abilities and to create a better image of our class．Most important of all，work painstakingly for a better condition that we should have reached可知作者希望班上所有的成员都能一起工作，创造一个更好的班级；故选D．第二节（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．选项中有两项为多余选项．7．（10分）Life is just like a box．Inside it are happiness and sorrow，failure and success，hope and despair （绝望）．Life is a learning process．Experiences in it teach us new lessons and make us a better person．LoveLove plays a key role in our life．Love makes you feel wanted．Without love a person could become cruel and violent．In the early stage of our life，our parents are the ones who show us with unconditional love and care．（36）C．But we always tend to take this for granted．It is only after marriage and having kids that a person understands and becomes sensitive to the feelings of others．Kids make a person responsible and mature and help us to understand life better．Happiness and SorrowMaterialistic（贪图享乐的）happiness is short﹣lived，but happiness achieved by bringing a smile on others gives a certain level of fulfillment （实现，满足）．（37）F．No mind is happy without peace．We realize the true worth of happiness when we are in sorrow．Sorrow is basically due to death of a loved one，failure and despair．But these things are temporary and pass away．Failure and Success（38）G．It helps us to touch the sky，teaches us to survive and shows us a specific way．Hope and DespairHope is what keeps life going．Parents always hope their children will do well．Hope makes us dream．Hope builds in patience．（39）B，because after every night there is a day．Nothing remains the same．We have only one choice﹣keep moving on in life and be hopeful．Life teaches us not to regret over yesterday，for it has passed and is beyond our control．Tomorrow is unknown，for it could either be bright or dull．（40）E，so that we will enjoy a better tomorrow．。

在南方生长的竹子，一般生长两年才能成为有用的竹材。
然而有些人出于急功近利的心理，没有等到竹子过冬，便把它们砍了下来，运到市场上去。
这样的竹子叫作“一年竹”。
表面看，“一年竹”似乎比生长两年的竹子更圆润饱满、俊俏挺拔，因而很受顾客欢迎。
然而由于缺少了寒冬的历练，“身子骨”没有经受过风雪霜的洗礼，这种竹子缺少韧性，易脆易折，不能成为上好的竹材；倘若用来做笛子，不仅音色不美，而且大都会因用力吹奏而在表面出现裂缝，无法使用。
上面的材料引发了你怎样的思考？请结合自己的体验与感悟，写一篇文章。
要求：①自选角度，自拟标题，自定文体；②不少于800字；③不得套作，不得抄袭。
二、（题型注释）2、依次填入下面一段文字横线处的词语，衔接最恰当的一组是（ ）《新华字典》是我国第一部① 白话释义和举例为特点的普及性小型汉语工具书，至今已连续出版了11个版本，总计销量约6亿册，2016年② 获得“最受欢迎的字典”、“最畅销的书”两项吉尼斯世界纪录，成为当代中国获得世界声誉的著名工具书。
60年来，《新华字典》③ 成为伴随每一代在国人成长的常备权威工具书，为昌明教育做出了卓越贡献。
④ ，《新华字典》，也是外国人学习中文的具有文化标准价值的工具书，曾在诸多外事活动中⑤ 国礼赠送给国际友人，是当之无愧的“国典”。
《新华字典》的编纂者和出版者也⑥ 将“国典”的编纂修订视作自己的文化责任，投入大量心血薪继火传，将《新华字典》打造成了零差错率的高品质辞书，在一定程度上起着知识规范的重要作用。

辽宁省抚顺市2016-2017学年高一下学期期末考试语文试题含答案
抚顺市六校联合体2016－2017下学期高一期末考试语文试卷本试卷分第I卷(阅读题)和第II卷(表达题)两部分，考试时间为150分钟，满分150分。
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)家谱也称族谱，是一种以表谱形式，记载一个以血缘关系为主题的家族世系繁衍的重要人物事迹的特殊图书体裁。
“夫家有谱、州有志、国有史，其义一也”。
家谱有约3000年的历史，素与国史、方志并称为“三大历史文献”，属珍贵的人文资料，是中国特有的文化遗产。
关于家谱的起，目前学术界众说纷纭，但是从出土的甲骨文、金文、碑文等中国早期文字，及史类文献对家谱起的考证，家谱的起至少可以追溯到先秦时代。
现今可以知道的最早的家谱雏形，是殷商时期留下的一片牛肩甲骨，现保存在大英博物馆，乃武丁时期所刻，是某一王室之外的显贵家族之记录。
另外，商周两代，还有刻录在青铜器上的金文家谱。
周代的《世本》，曾对创作《史记》有过参考作用，目前学术界公认它是中国家谱的开山之祖。
战国时代的《春秋公子血脉谱》，启我国家族史籍以“谱”名之先河。
周代的《世本》，在于“奠系世，辨昭穆”，它所奠的系世，是周宗室的帝王世系；所辨的昭穆，是尊卑贵贱的亲疏。
完全是为推行宗法分封制度，巩固周王朝统治服务的。
周代的宗法分封制度到了春秋战国时代已经“礼崩乐坏”，趋于瓦解。
到了汉高祖刘邦“徒步有天下”，宗族组织由兴到衰，由破坏到重建，至东汉时已由世族和宗族代替了，君统与宗统开始分离。
两汉的家谱功能是为恢复、重建宗族和形成、巩固世族的统治服务的。
魏晋南北朝时期，士族门阀势力极度膨胀，选用官吏实行九品中正制，“上品无寒门，下品无世家”，官之任用。
“不考人才行业，空辨姓氏高下”，“有司选举，必稽谱牒”，“家之婚姻，必由谱系”。
此时的家谱，成了政府选举、士族出仕、门第婚姻的主要依据。
与之适应的是修家谱之风极为盛行，国家设谱局，置谱官，“人尚谱系之学，家藏谱系之书”。
