Each word can only be used once. Note that there is one word more than you need.Since we are social beings, the quality of our lives depends in large measure on our interpersonal relationships. Our 41 of the human condition is our tendency to give and receive support from one another under stressful conditions. Social support consists of the 42 of resources among people based on their interpersonal ties. Those of us with 43 support systems appear better able to cope with major life changes and daily problems. People with strong social ties live 44 and have better health than those without such ties. Studies over a range of illnesses, from 45 to heart disease, reveal that the presence of social support helps people fight off illness, and the absence of such support makes poor health more likely.Social support cushions stress in a number of ways. First, friends, relatives, and co-workers may let us know that they 46 us. Our self-respect is 47 when we feel 48 by others despite our faults and difficulties. Second, other people often provide us with informational support. They help us to define and understand our problems and find solutions to them. Third, we typically find social companionship 49 . Engaging in leisure-time activities with others helps us to meet our social needs while at the same time distracting us from our worries and troubles. Finally, other people may give us instrumental support – financial aid, material resources, and needed services – that reduces stress by helping us resolve and cope with our problems.III. Reading Comprehension （50%）Section ADirections: For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each bank with the word or phrase that best fits the context.Specialists say it is not easy to get used to life in a new culture. “Culture shock” is the term these specialists 50 when talking about the feelings that people have in a new environment. There are three stages of culture shock, say the specialists. In the first stage, the 51 like their new environment. Then, when the fresh feeling 52 , they begin to dislike the city，the country, the people there, and 53 else. In the last stage, the newcomers begin to get used to their surroundings and，as a result, 54 their life.There are some obvious factors in culture shock. The weather may be unpleasant. The customs may be different. The public 55 system—the telephone, post office, or transportation—may be hard to work out. The simplest things seem to be big 56 . The language may be difficult.Who feels culture shock? Everyone does in this way or that. But culture shock still 57 most people. Very often the people having the worst culture shock are those who 58 had any difficulties in their home countries and were successful in their community. Coming to a new country, those people find they do not have 59 established positions. They find themselves without a role, almost without an identity. They have to build a new self-image. 60 makes them have a feeling of disorientation（无方向）. This feeling may be home-sickness. When homesick, people like staying 61 all the time. They want to protect themselves from the _ 62 _ environment, and create an escape anywhere for a sense of safety. This escape does solve the problem of culture shock for a _ 63 __term，but it does nothing to make the person familiar with the culture. Getting to know the new environment and _ 64 experience are the long-term solutions to the problem of culture shock.50．A．discover B．spend C．know D. employ51．A．specialists B．newcomers C．travellers D. people52．A．comes B．dies C．appears D. misses53．A．everything B．something C．anywhere D. somewhere54．A．satisfy B．realize C．enjoy D. find55．A．service B．society C．communication D. relation56．A．things B．ones C．problems D. misfortunes57．A．tires B．surprises C．ruins D. meets58．A．seldom B．ever C．once D. likely59．A．proper B．the same C．former D. the newly60.

Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.AHave you ever seen a traffic policeman with bright white sleeves, directing traffic at the busy road junction? That is my job.You would not guess how hard my job is unless you tried to do it yourself. I have to keep my eyes wide open every minute of the day, or else I will get myself and others into trouble. My negligence might even cause serious disaster.As soon as I take up duty on the traffic stand, I begin to wave my hands to direct the traffic. A traffic policeman should keep the movements of his arms down to a minimum and rely mainly on his hands in order to preserve his energy. I sometimes feel that y arms no longer belong to my body. Although it appears easy enough to stop on – coming cars from one direction and wave forward those from another direction, a traffic policeman must be most careful not to give any wrong signs lest an accident should occur.Nobody longs for fine weather as much as I do when I am on duty. Day or night, I pray that it will not rain. It is difficult to find anyone who is more exposed to the elements than I am in my traffic stand. The rain can drench me and the wind can chill me to the bone. On the other hand, during summer the hot sun can burn me!The most trying hours are the peak periods when people go to and come back from their work. At such times, both pedestrians and vehicles always seem to try to beat each other to the crossing. The motorists usually keep a sharp look – out for my signals, but many pedestrians walk across the road as if they are in a dream. They ignore my signals, risking their lives. Many pedestrians and motorists must have blamed me for stopping and holding them up. However, they should understand that the small inconvenience is for their own good.I like my job, for I believe that it does contribute, in a big way, to the maintenance of law and order.65．A traffic policeman .A．always wears white sleeves.B．gives directions to riders and pedestrians.C．is found only at busy road junctions.D．is a director for people.66．a traffic policeman should never for a moment neglect his duty, for .A．people depend on him for a living.B．the police station makes a very high demand on him.C．he is responsible for people’s safety.D．he should prevent disaster.67．In paragraph 4, “the elements” refers to in the passage.A．the bad weather B．the cold windC．the hot sun D．the heavy rain68．During rush hours, the traffic policeman’s signs .A．are useless at the crossing.B．don’t have any effect on motorists.C．can’t stop people from beating each other.D．are hardly observed by pedestrians.BKing’s College Summer SchoolKin g’s College summer School is an annual training program for high school students at all levels who wants to improve their English. Courses are given by the teachers of King’s College and other colleges in New York. Trips to museums and culture centers are also organized．This year's summer school will be from July 25 to August 15.More information is as follows:69．Which of the following is true about King' s College Summer School?A．Only top students can take part in the program.B．King' s College Summer School is run every other year.C．Visits to museums and culture centers are part of the program.D．Only the teachers of King' s College give courses.70．If you are to live with your relatives in New York, you will have to pay the school .A．$B．$400 C．$500 D．$90071．What information can you get from the text?A．The program will last two months.B．You can write to Thompson only in English.C．As a Chinese student, you can send your application on July 14, .D．You can get in touch with the school by e-mail or by telephone.C“Opinion” is a word that is used carelessly today. It is used to refer to matters of taste, belief, and judgment. This casual would probably cause little confusion if people didn’t attach too much importance to opinion. Unfortunately, most to attach great importance to it. "I have as much right to my opinion as you to yours, '' and ''Everyone's entitled to his opinion, '' are common expressions. In fact, anyone who would challenge another's opinion is likely to be branded intolerant.Is that label accurate? Is it intolerant to challenge another's opinion? It depends on what definition of opinion you have in mind. For example, you may ask a friend ''What do you think of the new Ford cars?" And he mayreply, "In my opinion, they're ugly." In this case, it would not only be intolerant to challenge his statement, but foolish. For it's obvious that by opinion he means his personal preference, a matter of taste. And as the old saying goes, ''It's pointless to argue about matters of taste."But consider this very different use of the term, A newspaper reports that the Supreme Court has delivered its opinion in a controversial case. Obviously the justices did not shale their personal preferences, their mere likes and dislikes, They stated their considered judgment, painstakingly arrived at after thorough inquiry and deliberation.Most of what is referred to as opinion falls somewhere between these two extremes. It is not an expression of taste. Nor is it careful judgment. Yet it may contain elements of both. It is a view or belief more or less casually arrived at, with or without examining the evidence.Is everyone entitled to his opinion? Of course, this is not only permitted, but guaranteed. We are free to act on our opinions only so long as, in doing so, we do not harm others.72．What does the word “label” refer to?A．The lack of deliberation will probably be unable to put up with another’s opinion.B．Careless thought will direct people into trouble.C．To be frank is the best way to be one’s best friend.D．Great importance is attached to one’s opinions in one way or another.73．The new Ford cars are cited as an example to show that ________.A．personal tastes are not something to be challenged.B．A famous brand is not something to be challenged.C．Free expressions of opinions will lead to confusion.D．To confront a personal opinion in public is tolerant.74．Considered judgment is different from personal preference in that ________.A．Considered judgment is always delivered in the court.B．Considered judgment states on e’s likes and dislikes.C．Considered judgment results from careful thought.D．Considered judgment covers one’s personal preferences.75．As indicated in the passage, being free to act on one's opinion ________.A．means that one can ignore other people's criticism.B．means that one can impose his pre6ereaccs on others.C．doesn't mean that one has the right to charge others without evidence.D．doesn't mean that one has the right to do things at will.DSex prejudices are based on and justified by the ideology that biology is destiny. According to this ideology, basic biological and psychological differences exist between the sexes. These differences require each sex to play a separate role in social life. Women are the weaker sexboth physically and emotionally. Thus, they are naturally suited much more so than men, to the performance of domestic duties. A woman's place, under normal circumstances, is within the protective environment of the home. Nature has determined that women play caretaker roles, such as wife and mother and homemaker. On the other hand, men are best suited to go out into the competitive world of work and politics, where serious responsibilities must be taken on. Men are to be the providers; women and children are "dependents".The ideology also holds that women who wish to work outside the household should naturally fill these jobs that are in line with the special capabilities of their sex. It is thus appropriate for women, not men, to be employed as nurses, social workers, elementary school teachers, household helpers, and clerks and secretaries. These positions are simply an extension of women's domestic role. Informal distinctions between "women's work" and "men's work" in the labor force, according to the ideology, are simply a functional reflection of the basic differences between the sexes.Finally, the ideology suggests that nature has worked her will in another significant way. For the human species to survive over time, its members must regularly reproduce .Thus , women must, whether at home or in the labor force, make the most of their physical appearance. So goes the ideology. It is, of course, not true that basic biological and psychological differences between the sexes require each to play sex defined roles in social life. There is ample evidence that sex roles vary from society to society, and those role differences that to exist are largely learned.But to the degree people actually believe that biology is destiny and that nature intended for men and women to make different contributions to society, sex defined roles will be seen as totally acceptable.76．Women's place, some people think, is within the protective environment of the home because_______ .A．women can provide better care for the childrenB．women are too weak to do any agricultural work at allC．women are biologically suited to domestic jobsD．women can not compete with men in any field77．According to the author, sex roles _______.A．are socially determinedB ．are emotionally and physically determinedC ．can only be determined by what education people takeD ．are biologically and psychologically determined78．The author points out that the assignments of women's roles in work_______. A ．are determined by what they are better suited toB ．grow out of their position inside the homeC ．reflect a basic difference between men and womenD ．are suitable to them, but not to men79．Which of the following is NOT true according to the passage? A ．The division of sex defined roles is completely unacceptable .B ．Women's roles in Work are too limited at present.C ．In one society, men might per form what is considered women's duties by another.D ．Some of the women's roles in domestic duties can not be taken over by menSection CDirections: Read the following text and choose the most suitable heading from A – F for each paragraph. There is one extra heading which you do not need.E80．Asakawa, 45, has spent the past eight years making the Internet a friendly place for people who can ’t see. In 1997 her research group at IBM Japan put out one of the world ’s first browsers specifically made to read aloud the contents of Web pages. And last July, her team released software that helps Web designers figure out how to make their home pages accessible to people with poor or no eyesight. 81．______Accessibility is a serious issue. The Internet is becoming an increasingly important source of information and services. For people who are blind, the Internet lets them do things on their own for which they previously needed a lot of help, like going shopping.82．_______At age 11, Asakawa accidentally hit her head into the side of a pool while swimming, damaging her optic （视觉的）nerves. Three years later, she was completely blind. At a vocational school for the blind, Asakawa learned to program in various computer languages. To read code printouts she used a device that translated the code into raised letters sensed with the fingers. It was a struggle, she recalls, “ But it was possible.”83．________In the mid-1990s, she began surfing the Internet, using a combination of software that read out what was on the screen. But there were problems: The system only read English. On-screen fill-out forms stumped the reader, and tables with vertical columns came out as gibberish（无意义的声音）. Asakawa decided to develop software specifically designed to handle the coding used for Web pages. She inserted aural cues to help browsing, like using a man’s voice for text and a woman’s for links. In 1997 she put ou t IBM’s first Home Page Reader in Japanese, then in English followed by nine other languages.84．______Asakawa is now doing basic research on using the sense of touch to direct the attention of the blind, as colors do for the sighted. She hopes this kind of research will also be usefu l for people with normal vision. “ Sighted people don’t use the sens e of touch very much,”she laughs. “What a waste！＂第Ⅱ卷（共45分）I.

x函数图象下降，即为减函数，且函数图象过（0，1），而曲线y=log a﹣x函数图象上升，即为增函数，且函数图象过（﹣1，0），以上图象均不符号这些条件；若a＞1，则曲线y=a x上升，即为增函数，且函数图象过（0，1），而函数y=log a﹣x下降，即为减函数，且函数图象过（﹣1，0），只有选项B满足条件．故选：B．【点评】此题考查了指数函数及对数函数的图象与性质．这类题的做法一般是根据底数a

上海市南汇中学2024-2025学年高一上学期10月月考英语试卷一、语法填空Directions: After reading the passage below, fill in the blanks to make the passage coherent and grammatically correct. For the blanks with a given word. fill in each blank with the proper form of the given word; for the other blanks, use one word that best fits each blank.Do You Share Too Much Online?It’s good to share, right? Growing up as kids, we 1 (tell) to share our toys and not to be selfish. We also live in an age 2 discussing our feelings is encouraged. But when does it all become too much? With new crazes trending all the time, such as dance challenges and 3 (wear) a pillow as a dress, the question is: when can sharing become oversharing on social media?What is oversharing? The term 4 (associate) with social media since it was coined, but it isn’t exclusive to this platform. Imagine you ha ad to a party and you meet someone. Within five minutes they have exposed private details 5 their life. While some of us may try to escape these people, this form of oversharing could come from a strong desire 6 (connect) with someone. But how does this translate to social media?Dr Christopher Hand, a lecturer in cyber psychology, says the more details people disclose, the less sympathy we express when things go wrong. 7 seems that the idea of searching for sympathy by oversharing, is generally understood as negative. However, Dr Hand’s research also seems to suggest that the more we post on a platform, the more socially attractive we become, 8 our posts are positive. Even back in 2015, Gwendolyn Seidman PhD, advised that we avoid complaining online.So, how can you know if you are oversharing? Well, why not 9 (ask) your friends in real life? They would probably be more than happy to tell you 10 your posts about your breakfast or your complaints about your lack of money really are too much.二、选词填空Directions: Complete the following passage by using the words in the box. Each word can only be used once. Note that there is one word more than you need.In recent years, sustainable tourism has gained widespread approval as more travelers become aware of the environmental and social impacts of traditional tourism. Originally considered a low-value market, sustainable tourism has evolved into a11 industry that offers particular benefits to both the environment and local communities. This form of tourism 12 aims to reduce the negative effects of travel while enhancing the social, cultural, and economic well-being of destinations.One of the primary advantages of sustainable tourism is its ability to preserve natural resources and protect fragile ecosystems. By 13 environmentally responsible practices such as reducing waste, conserving water, and minimizing carbon footprints, sustainable tourism ensures that tourist hotspots 14 attractive. This not only benefits the environment but also guarantees that these natural attractions will still be 15 for future generations to enjoy.Additionally, sustainable tourism con provide significant economic astatine to local communities. Unlike traditional large-scale tourism projects, which often force locals to 16 to other places, sustainable tourism promotes employment opportunities for local people by maximizing the use of local resources. Whether by purchasing handmade goods, or by dining in family-run restaurants, traveler help 17 the economic gap between tourists and local populations, supporting local livelihoods,However, implementing sustainable tourism practices is not without its challenges. Some destinations 18 to market themselves as eco-friendly without making genuine efforts, a practice known as “greenwashing.” This makes it essential for travelers to be aware of which businesses and destinations truly prioritize sustainability.In conclusion, sustainable tourism offers endless potential to make travel more environmentally friendly and socially 19 . By making more conscious choices, tourists can leave a positive 20 on the places they visit while enjoying unique and unforgettable experiences.三、完形填空When we think about lives filled with meaning, we often focus on people whose grand contributions benefited humanity. Abraham Lincoln, Martin Luther King, Jr., and Nelson Mandela surely felt they had a worthwhile life. But how about us ordinary people, burying ourselves in a(n) 21 existence?Many scholars 22 a subjectively meaningful life to three factors: the feeling that one’s life makes sense (coherence), the possession of clear and satisfying long-term goals (purpose) and the belief that one’s life matters in the overall scheme of things ( 23 mattering).But we believe there is another element to consider. Think about the first butterfly you stop to admire after a long winter. Sometimes existence delivers us small moments of beauty. When people are 24 to appreciating such experiences, these moments may enhance how they view their life. We call this element experiential appreciation, which represents the detection of and 25 for life’s inherent beauty.To better understand this form of appreciation, we conducted a series of experiments in which we gave people specific tasks and asked them to report how strongly they 26 statements linked to the factors of meaningful life. In one case, we found that participants who watched an awesome video, such as the BBC documentary Planet Earth, reported having a greater sense of experiential appreciation and meaning in life, compared with participants watching more 27 videos, such as an instructional woodworking video. 28 , participants who wrote about a recent experience for which they were 29 had a greater sense of meaning when compared with those who simply wrote about a common place they had 30 last week.The results confirmed our original theory: people are born with the ability to appreciate beauty, and appreciating small things can make life feel more meaningful. But 31 that insight can be difficult. Our modern, fast-paced, 32 lifestyles fill the day with targets. We attempt to 33 output both at work and at leisure. This focus on future outcomes makes it all too easy to miss what is happening right now. Yet life happens in the present moment. We should slow down, let life surprise us and 34 the significance in the everyday.

But last year she rarely made it to the doors of Rock Bridge High School by the first bell, at 7:50 a.m.Then she heard that the school board was about to make the day start even earlier, at 7:20 a.m.“I think if that happens,” recalled Jilly, 17. “I will have to drop out of school. And I will complain to the end!”The nearly 20-year movement to start high schools later has recently gained momentum as hundreds of schools in dozens of districts across the country have adopted later school starting time.These schools have referred to the accumulating research results on the adolescent body clock. Evidence suggests that later high school starts have widespread benefits. Researchers at the University of Minnesota found that the later a school’s start time, the better off the students were on many measures, including mental health, car crash rates, attendance and, in some schools, grades and standardized test scores.“The research was not a randomized controlled trial. Its methods were practical and findings were promising. Even schools with limited resources can make this one policy change with what appears to be benefits for their students,” Dr. Elizabeth Miller said.Researchers have found that during adolescence, as hormones(荷尔蒙) rise and the brain develops, teenagers who regularly sleep eight to nine hours a night are less likely to be tardy, get in fights or sustain athletic injuries. Sleeping well can also help to stop their tendency toward uncontrolled or risky decision-making.During adolescence, teenagers have a later release of the “sleep” hormone melatonin(褪黑素), which means they tend not to feel sleepy until around 11 p.m. This explains mainly for their late bed time and naturally leads to late rising time. Other minor factors include the presence of electronic devices, which excites the brain and slows the onset of sleep. The Minnesota study noted that 88 percent of the students kept a cellphone in their bedroom.But many parents object to shifting the start of the day later. They say doing so makes sports practices end late, jeopardizes student jobs and bites into time for homework.At heart, though, experts say, the resistance is driven by mistrust about the primacy of sleep. “It’s still a badge of honor to get five hours of sleep,” said Dr. Judith Owens. “It supposedly means you’re working harder, and that’s a good thing. So there has to be a cultural shift around sleep.”36．Why do many schools decide to start school later?A．Because they respond to complaints from students like Jilly.B．Because some students dropped out of school because of early start.C．Because they find later start brings various benefits.D．Because they would like to copy the way of other schools in districts.37．Which of the following statements is TRUE according to the passage?A．According to research, all the students experience higher academic grades because of later school starts.B．Enough sleep helps to prevent teenagers from making willful decisions.C．Later school starts are not suitable for schools with limited resources.D．The leading reason for students’ sleeping late is the existence of mobile phones. 38．The underlined word “jeopardizes” is closest in meaning to________.A．harmsB．introducesC．freesD．exchanges39．According to experts, many parents are against late school starts mainly because_____.A．they tend to object to all decisions schools makeB．they are afraid that homework time will be cutC．they fear students will get poor test resultsD．they doubt the advantages of enough sleepComputers can beat world chess champion Gary Kasparov at his game, count all the atoms in a nuclear explosion, and calculate complex figures in a fraction of a second, but they still fail at the slight differences in language translation. Artificial Intelligence computers have large amounts of memory, capable of storing huge translating dictionaries and extensive lists of grammar rules. Yet, today’s best computer language translators have just a 60 percent accuracy rate. Scientists are still unable to program the computer with human-like common sense reasoning power.Computer language translation is called Machine Translation, or MT. While not perfect, MT is surprisingly good. MT was designed to process dry, technical language that people find tedious to translate. Computers can translate basic phrases, such as “Your foot bone’s connected to your ankle bone, your ankle bone’s connected to your leg bone.” They can translate more difficult phrases, such as “Which witch is which?” Computers can also accurately translate “Wild thing, you make my heart sing!” into other languages because they can understand individual words, as long as the words are pre-programmed in their dictionary.But highly sensitive types of translating, such as important diplomatic conversations, are beyond the scope of computer translating programs. Human translators use intuitional meaning, not logic, to process words and phrases into other languages. A human can properly translate thephrase, “The pen is in the pen (围养禽畜的圈),” because most humans know that it means that a writing instrument is in a small enclosed space. Many times, computers do not have the ability to determine in which way two identical words in one sentence are to be used.In addition to using massive rule-programmed machines, computer programmers are also trying to teach computers to learn how to think for themselves through the “experience” of translating. Even with these efforts, programmers admit that a “thinking” computer might not ever be invented in the future.40．Computers today are capable of ________.A．defeating the best chess player in the worldB．telling subtle differences between languagesC．translating over 60 percent of difficult textsD．doing human-like common sense reasoning41．According to the passage, which of the following is NOT true?A．Computers can translate dry and difficult phrase.B．Computers can translate technical language.C．Computers can understand pre-programmed word.D．Computers can understand sensitive language.42．To improve machine translation, computer programmers are trying to ________.A．use powerful rule-programmed computersB．have computers compile translating dictionariesC．teach computers to think by practiceD．add explanations of words in computer programs43．The passage suggests that ________.A．the accuracy rate of machine translation cannot be raisedB．it is impossible for computers to think as humans doC．only technical language is suitable for machine translationD．it is impossible to determine identical wordsWater is a key ingredients in a healthy diet and lifestyle.There are many health benefits of drinking water. It helps flush impurities and toxins out of our systems. 44 In fact, nearlyevery system in our bodies relies on water for proper functioning. But what will happen if the water you drink every day is unhealthy?In past decades, concerns about tap water and its impact on overall health led some people to tun to bottled waters. You could pay to have a company deliver large bulky plastic bottles of water for the water cooler. Or you could purchase gallon jugs of distilled or “drinking water” at the grocery store.In recent years, there has been an explosion in the number of different bottled waters available, with big distributors such as Coke and Pepsi jumping on the bandwagon. But are bottled drinking waters like Coke’s Dasani brand, Pepsi’s Aquafina, or Wal-Mart’s store brand really any healthier than your tap water? 45As we have learned more about the water we drink,the technology behind drinking water filters and purification systems has improved dramatically. There are filters to remove impurities, chemicals,heavy metals, bacteria and almost every contaminant you can think of.With the right size and filter combination for your specific home, your tap water can be exceptionally pure and healthy.46 Although the initial cost of a whole house system usually amounts to several hundred dollars,that cost is often less than $100 a year if spread out over the life of the system.There may be additional expenses to replace carbon filters or lamps in an ultraviolet light water treatment device. These expenses can add another $100 or so to the annual cost of operating drinking water filters and purification systems.While some people may hesitate to spend so much each year for clean, safe drinking water, they are probably paying more for bottled drinking water. They understand that it is more expensive, but they are still willing to pay the extra money because bottled water is thought to be safer and healthier than filtered drinking water. 47 In reality, however, few bottled waters come from natural springs,and most of them use municipal tap water.A．Drinking water filtration systems have also become more affordable and easy to use. B．After all, bottled water is often marketed as “natural spring water” or “pure glacier water.”C．It aids in the delivery of oxygen and nutrients.D．And with a water filter, you at least know where the water you drink came from.E．Or would you be better off with a drinking water filtration system?F．So how do you tell if the water you are drinking is safe?五、选词填空Directions: Complete the following sentences with the given phrases in their proper forms. Each phrase can only be used once.48．After living in the city for years, now she the constant noise and traffic.49．He didn’t expect too much from the competition, but he winning the first place. 50．After realizing how much his careless comments hurt his friend, he his behavior and promised to be more mindful.51．His constant excuses and lack of effort in completing the project nothing more than an attempt to avoid responsibility.52．The teacher frequently the students’ previous assignments to explain how they could avoid common mistakes in the future.53．The company’s current marketing strategies extensive consumer research, focusing on understanding customer needs and preferences to deliver more effective advertising campaigns.六、翻译54．他总是长时间地工作。
