I think thirty dollars per month is no small amount of money for a student.To be honest, I don’t need to use a cell phone because I don’t have any urgent business, but all my family and friends have cell phones. More than fifty percent of the population in Korea（韩国）has a cell phone. Think about that number: only children and very old people don’t have one.If I didn’t have a cell phone, everybody would raise such a question, “Why doesn’t she have one?” I would be considered as a strange and independent person. Korea has agroup-oriented culture, so a strange and independent p erson isn’t welcome. I don’t want to be strange, so I cannot do anything but use a cell phone.I have to check my cell phone all the time, and I have to change the battery every other day. It is kind of a big problem. Even though I don’t want to answer the phone at all, I have to answer it because as long as I have a cell phone, a quick answer is etiquette（礼节）. It has really invaded（影响）my life. I have never thought cell phones are useful and meaningful devices. I hate them because I am a person who likes to lead a peaceful, calm life. I wish I could get rid of my cell phone in the near future.Directions: Choose the best answer from the four choices.6.

精品解析：山东省滨州市滨城区2021-2022学年七年级上学期期末语文试题(解析版)
13.虽然写了一场败仗却并不令人丧气，而是败中见豪气。第一句“碎铁衣”明写破碎的铁衣，实写铮铮铁汉；第四句中的“独“字几乎有千斤之力压倒了敌方的千军万马，给人以顶天立地之感。能够突显英勇。
【解析】
【12题详解】
本题考查古诗重点词语的理解。“突营射杀呼延将”的意思是：突进营垒，射杀敌军大将。一个“突”写出身经百战的英雄作战的机智，出其不意攻其不备；“射杀”一词极力表现了英雄“擒贼先擒王”的胆略和果敢。因此，“突”和“射杀”两词语需重读。“突营射杀呼延将”表现了将士的雄才壮志、果敢英勇，在读此句时应带有潇洒豪迈之情。
（第九十七回）
【答案】示例：三次遇到强盗，孙悟空用了三次不同的解决办法，第一次全部打死，第二次只打死领头的，第三次把强盗抓起来报官。从这些强盗们的下场可以看出孙悟空的性格变化是：从一开始的冲动任性，到愿意区分好坏，再到最后的遇事冷静，遵纪守法。
【解析】
【分析】
【详解】本题考查分析人物形象的能力。由【片段一】“被他拽开步，团团赶上，一个个尽皆打死”，结合原著第十四回“行者笑道：‘将就看得过罢了！你们也打得手困了，却该老孙取出个针儿来耍耍。’那贼道：‘这和尚是一个行针灸的郎中变的。我们又无病症，说甚么动针的话！’行者伸手去耳朵里拔出一根绣花针儿，迎风一幌，却是一条铁棒，足有碗来粗细，拿在手中道：‘不要走！也让老孙打一棍儿试试手！’唬得这六个贼四散逃走，被他拽开步，团团赶上，一个个尽皆打死。剥了他的衣服，夺了他的盘缠”可见强盗在想要逃走时，被孙悟空全部打死。由【片段二】“吓得那众娄罗撇枪弃棍，四路逃生而走”，结合原著中“行者笑道：‘你也打得手困了，且让老孙打一棒儿，却休当真。’你看他展开棍子，幌一幌，有井栏粗细，七八丈长短，荡的一棍，把一个打倒在地，嘴唇揞土，再不做声。那一个开言骂道：‘这秃厮老大无礼！盘缠没有，转伤我一个人！’行者笑道：‘且消停，且消停！待我一个个打来，一发教你断了根罢！’荡的又一棍，把第二个又打死了，唬得那众娄罗撇枪弃棍，四路逃生而走。”可见，第二次只打死了领头的，而让其他的逃走了。由【片段三】“教他供一个供状”，结合原著“行者即拔下些毫毛，吹口仙气，变作三十条绳索，一齐下手，把贼扳翻，都四马攒蹄捆住，却又念念解咒，那伙贼渐渐苏醒”“行者欲将这伙强盗一棍尽情打死，又恐唐僧怪他伤人性命，只得将身一抖，收上毫毛。那伙贼松了手脚，爬起来，一个个落草逃生而去。这唐僧转步回身，将财物送还员外。”可见第三次孙悟空是把强盗抓起来报官。由此可得出其性格的变化过程是：从一开始的冲动任性，到愿意区分好坏，再到最后的遇事冷静，遵纪守法。

(完整版)大一英语上学期期末考试试卷2022级高校英语第一学期期末考试(A卷)Jan., 2022Part II Reading Comprehension (30 %) Directions: There are four passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) andD). You should decide on the best choice and mark the corresponding letter on theAnswer Sheet with a single line through the center.Passage OneScience is not a set of unquestionable results but a way of understanding the world around us. Its real work is slow. The scientific method , as many of us learned in school, is a gradual process that begins with a purpose or problem or question to be answered. It includes a list of materials, a procedure to follow, a set of observations to make and, finally, conclusions to reach. In medicine, when a new drug is proposed that might cure or control a disease, it is first tested on a large random group of people, and their reactions are then compared with those of another random group not given the drug. All reactions in both groups are carefully recorded and compared, and the drug is evaluated. All of this takes time and patience.It’s the result of course, that makes the best news—not the years of quiet work that characterize the bulk of scientific inquiry. After an experiment is concluded or an observation is made, the result continues tobe examined critically. When it is submitted for publication, it goes to a group of the scientist’s colleagues, who review the work. Einstein was right when he said: “No amount of experimentation can ever prove me right, a single experiment can at any time prove me wrong.”In August 1996, NASA announced the discovery in Antarctica of a meteorite（流星）from Mars that might contain evidence of ancient life on another world. As President Clinton said that day, the possibility that life existed on Mars billions of years ago was potentially one of the great discoveries of our time.After the excitement wore down and initial papers were published, other researchers began looking at samples from the same meteorite. Some concluded that the “evidence of life”was mostly contamination from Antarctic ice or that there was nothing organic at all in the rock.Was this a failure of science, as some news reports trumpeted?No! It was a good example of the scientific method working the way it is supposed to. Scientists spend years on research, announce their findings, and these findings are examined by other scientists. That’s how we learn. Like climbing a mountain, we struggle up three feet and fall back two. It’s a process filled with disappointments and reverses, but somehow we keep moving ahead.21. The author’s main purpose in writing this passage is to state that ____________.A) most scientific discoveries are not reliableB) mass media is misleading because it looks at the research results onlyC) scientific research is a process filled with reverses and requiresslow and patientworkD) repeated experiments are necessary before medicine can be used in patients22. Publication of a scientific finding signifies __________.A) a challenge to fellow scientists to prove it wrongB) the end of a processC) the beginning of a new scientific inquiryD) the soundness of the result23. Einstein’s words are used to show that he thought___________.A) experiments have proved him rightB) scientists do not need so many experimentsC) one experiment is not enough to prove him wrong.D) scientific ideas are never free from challenge24. NASA’s announcement of the discovery of evidence of ancient life on Mars shows _________.A) the way human beings learn about natureB) the failure of the scientific methodC) the fruitlessness of human search for life on another worldD) the excitement brought by scientific findings25. It can be inferred from the passage that the media is interested in __________.A) the process of scientific researchB) the results of scientific researchC) the scientists who do the researchD) the effects of scientific research on human lifePassage TwoNormally a student must attend a certain number of courses in order to graduate, and each course which he attends gives him a credit which he may count towards a degree. In many American universities the total work for a degree consists of thirty-six courses each lasting for one semester. A typical course consists of three classes per week for fifteen weeks; while attending a university a student will probably attend four or five courses during each semester. Normally a student would expect to take four years attending two semesters each year. It is possible to spread the period of work for the degree over a longer period. It is also possible for a student to move between one university and another during his degree course, though this is not in fact done as a regular practice.For every course that he follows a student is given a grade, which is recorded, and the record is available for the student to show to prospective employers. All this imposes a constant pressureand strain of work, but in spite of this some students still find timefor great activity in student affairs. Elections to positions in student organizations arouse much enthusiasm. The effective work of maintaining discipline is usually performed by students who advise the academic authorities. Any student who is thought to have broken the rules, for example, by cheating has to appear before a student court. With the enormous numbers of students, the operation of the system does involve a certain amount of activity. A student who has held one of these positions of authority is much respected and it will be of benefit to him later in his career.26. Normally a student would at least attend __________classes each week.A) 36B) 12C) 20D) 1527. According to the first paragraph an American student is allowed _______.A) to live in a different universityB) to take a particular course in a different universityC) to live at home and drive to classesD) to get two degrees from two different universities28. American university students are usually under pressure of work because_________.A) their academic performance will affect their future careersB) they are heavily involved in student affairsC) they have to observe university disciplineD) they want to run for positions of authority29.Some students are enthusiastic for positions in student organizations probablybecause_________.A) they hate the constant pressure and strain of their studyB) they will then be able to stay longer in the universityC) such positions help them get better jobsD) such positions are usually well paid30. The student organizations seem to be effective in _________.A) dealing with the academic affairs of the universityB) ensuring that the students observe university regulationsC) evaluating students’ performance by bringing them before a courtD) keeping up the students’ enthusiasm for social activitiesPassage ThreeDoreen Sykora is now a junior at Mcgill University. She had a difficult time when she first began college. She said, “I was always well prepared for my examinations. But I would go in to class to take the exam, and I would fall apart. I could not answer the questions correctly-----even though I knew the answers! I would just blank out because of nervousness and fear.”HitoshiSakamoto, an anthropology student at Temple University in Tokyo reports similar experiences.These two young students were experiencing something called test anxiety. Because a student worries and is stressed about a test, his or her mind does not work as well as it usually does. The student cannot write or think clearly because of the severe tension and nervousness.Now there are special university courses to help students. In these courses, advisors and psychologists try to help students by teaching them to manage test anxiety. Such a course helps students learn to live with stress and not fail because of it. First students take a practice test to measure their worry level. If the tests show that their stress level is high, the students can take a short course to manage the fear. These courses teach students how to relax their bodies. They get training to become calm in very tense situations. By controlling their nervousness, they can let their minds work more easily. Learned information then comes out without difficulty on a test.Doreen Sykora saw immediate results after taking such a course. She now has enthusiasm about the relaxation methods. “Mostly, what I do is imagine myself in a very calm place. Then I imagine myself picking up a pencil. I move slowly and carefully. I breathe easily and let all the tension out. With each breath, more worry leaves me. It really works too. My grades have improved greatly! I’m really doing well at McGill now. This relaxation method works not only on examinations, but it has improved the rest of my life as well.”For Hitoshi in Tokyo, the results were much the same. He is enjoying school a lot more and learning more.31. Doreen Sykora and Hitoshi Sakamoto were filled with nervousness and fear duringexaminations because they were__________.A) not ready and unaware of the answersB) physically so weak that they fell apartC) subject to test anxietyD) unable to write or think clearly32. The higher the students’ worry level is, __________.A) the less calm and relaxing they areB) the more difficult they will be trained to manage fearC) the more stressed and tense they areD) the longer courses they will take to manage fear33. What’s the purpose of some special university student-help courses?A) To help students to reduce test anxiety.B) To show a stress level experienced by students.C) To learn more knowledge about test anxiety.D) To have a better understanding of test anxiety.34. What’s the meaning of “blank out” in paragraph one?A) To be like a blanket.B) To be sure of an answer.C) To be relaxed.D) To be unable to think clearly.35.Which of the following best sums up the organization of the passage?A) Examples----theories----ideas.B) Problem----strategy----examples----results.C) General statement----examples----result.D) Strategy----experiment----examples.Part III V ocabulary and Structure (15 %) Directions: There are 30 incomplete sentences in this part.

It needs exercise. Mental (心理的) exercise is particularly important for young children. Many child psychologists(心理学家) think that parents should play with their children more often and give them problems to think about. The children are then more likely to grow up bright and intelligent. If, on the other hand, children are left alone a great deal with nothing to do, they are more likely to become dull and unintelligent.Parents should also be careful with what they say to young children. According to some psychologists, if parents are always telling a child that he or she is a fool or an idiot, then the child is more likely to keep doing silly and foolish things. So it is probably better for parents to say very positive (helpful) things to their children, such as “That was a very clever thing you did.” or “You are such a smart child.”Choose the right answer according to the passage.1. The words “intelligent” and “brilliant” in the first paragraph probably mean _______ while “dull” in the second paragraph means ________.A. bright and splendid; slow in thinking and understandingB. pretty and handsome; ordinary-lookingC. great and important; commonD. hopeful and helpful; careless2. According to the context we can guess that a genius is ________ while an idiot is ________.A. a normal person; a funny personB. a strong person; a weak personC. a highly intelligent person; a foolish or weak-minded personD. a famous person; an ordinary person3. A person ________ is more likely to become a genius.A. whose parents are cleverB. often thinking about difficult problemsC. often helped by his parents and teachersD. born with a good brain and putting it into active use4. It is better for parents ________.A. to praise and encourage their children more oftenB. to be hard on their childrenC. to leave their children alone with nothing to doD. to give their children as much help as possible5. Which of the following is NOT true according to the article?A. Parents play an important part in their children’s growth.B. The less you use your mind the duller you may become.C. Intelligence is obviously the result of where and how you live.D. What makes a person bright or stupid is still under discussion.Task 2It is known to us that English is not as old as Chinese, but it is widely used by most people all over the world. English speakers enjoy creating new words. In fact, a majority of words are traceable（可追踪的）and each of them may have an interesting story.However, no one will really care where a word comes from because it makes little difference in using them in our daily life. Did you ever feel confused about why hamburgers are called hamburgers, especially when they are not made with ham(火腿)?About a hundred years ago, some men went to American from Europe, coming from a big city in Germany called Hamburg. They didn't know how to use English properly. Seen them eating round pieces of beef and asked what it was, the Germans didn't understand the questions exactly, they answered: “we come from Hamburg. “One of the Americans was an owner of a restaurant and got an idea. He cooked some round pieces of bread with beef and began selling them. Such bread came to be called “hamburgers”. Today, hamburgers are welcomed by lots of people coming from different nationalities（民族）.Choose the right answer according to the passage.6. According to the text, English is __ .A) older than ChineseB) as old as ChineseC) not so old as ChineseD) very hard to learn7. Hamburg originally is ___.A) a kind of foodB) a round piece of beefC) a city in GermanyD) the name of a village8. Which statement is correct according to the passage.'? ___A) At first hamburgers was a kind of bread.B) Few Americans like hamburgers.C) Hamburgers are made of ham.D) Hamburgers were first sold a century ago.9. __ begin to sell hamburgers to people.A) AmericansB) The authorC) GermansD) Europeans10. After reading this story, we know the word “hamburger” comes from ____.A) China because it has a long historyB) English because Germans don't speak EnglishC) English speakers because they love eating itD) America because they give it that nameTask 3The most important thing to remember about the weather in Britain is that it often changes. You can wake up to a beautiful blue sky and then it starts raining during breakfast. Similarly, you may decide not to go f or a picnic because it‘s too wet —then later it’s fine. As it is not very common in Britain to have long periods when the weather stays the same day after day, the kind of weather you get will depend not only on the time of year, but also on luck.The weather in Britain may explain a lot about what you find here. For example, the opportunities for people to meet outside depend a lot on the weather, so you won‘t see people meeting and spending time together outdoors as much as you do in hotter countries. This may give some visitors the idea that the British are not very friendly. The weather helps to explain eating customs（习俗）too; a large hot breakfast, for example, is a good idea on a cold dark morning.Foreigners are often amused（感到好笑的）that the British spend so much time discussing the weather. An important reason for this is that the climate in Britain is interesting and variable多变的.Because the weather changes frequently（频繁地）,there‘s always something to say about it. This is probably the commonest way for strangers to start a conversation. At places like bus stops you might hear conversations start like this:1st person: Lovely day, isn't it?2nd person: Yes, isn't it?Then they go on to talk about what the weather has been like recently or what it‘ll be like next day. Another reason is that the British are reluctant to（不情愿地）converse（谈论）about personal matters with people who are not friends. Mentioning the weather is also a useful way to greet someone you pass on the street; it’s inoffensiv e（无伤害的）to begin a conversation with someone you don‘t know at a social event. A comment on a nice day or a personal complaintabout the rain is an easy way to break the ice.Are the following statements true or false according to the passage? Write T / F accordingly.11（）People in Britain can enjoy lovely weather most of the year.12（）British people tend to talk about weather quite a lot.13（）The eating habits of people in Britain have a lot to do with the weather conditions there.14（）The best word we may use to describe the weather in Britain is “predictable”.15（）Talking about weather is an inoffensive way to begin a conversation with a stranger in Britain.Task 4Dear Chinese Friends,Tonight, we will soon come to the end of 16 glorious days which we will cherish forever.Thank-you to the people of China, all the wonderful volunteers and BOCOG（奥运会北京组委会）!Through these Games, the world learned more about China, and China learned more about the world. Athletes from 204 National Olympic Committees came to these dazzling venues and awed us with their talent.New stars were born. Stars from past Games amazed us again. We shared their joys and their tears, and we marveled at their ability. We will long remember the achievements we witnessed here.As we celebrate the success of these Games, let us all together wish the best for the talented athletes who will soon participate in the Paralympic Games(残奥会). They also inspire us.To the athletes tonight: You were true role models. You have shown us the unifying power of sport. The Olympic spirit lives in the warm embrace of competitive rivals（竞争对手）from nations in conflict. Keep that spirit alive when you return home.These were truly exceptional Games!And now, in accordance with tradition, I declare the Games of the XXIX Olympiad closed, and I call upon the youth of the world to assemble four years from now in London to celebrate the Games of the XXX Olympiad.Thank you!Are the following statements true or false according to the passage? Write T / F accordingly.16（）Mr. Jacques Rogge gave his thanks to the Chinese people and the volunteers in his closing speech.17（）The 29th Olympics saw 204 athletes from all over the world.18（）Mr. Jacques Rogge expressed his best wishes to the athletes who were going to participate in the Paralympics.19（）Mr. Rogge declared the XXX Olympic Games closed.20（）The 16-day 29th Olympics will leave the world forever with the memory of the achievements of talented athletes and the Olympic spirit.四、翻译5*3´=15´分Translate the following sentences into Chinese.1. If you want to say “Hello” to everyone on the planet, you would have to learn at least 2796 languages.2.The injured party may suffer from personal, financial or other damages.3.The new model of the cell phone is priced anywhere from $100 to $500.4.Brazilians are not punctual by American standards.5.Similarly, you can download the kind of software you like.五、写作20*1´=20´分Write a business card according to the information given in Chinese.滨海电子有限公司李铁刚电子工程师地址: 滨海市长江路50号电子邮件：ltg6@电话：0411-4673***手机：1362512****。
