2023-2024学年四川省成都市第七中学 (高新校区)高一上学期10月月考英语试题If you’re interested in pushing yourself academically while experiencing college life, our Summer Programs for Pre-College Students (SPP) can be ideal for you. In the programs, you will be able to make friends with fellow students, engage in social activities around the city and on campus, and experience pre-college summer study at one of the world’s top teaching and research universities.Our long-running summer term pre-college offerings include a choice of one-, two-, three-, and six-week programs that prepare you for success in college. With five exciting and challenging pre-college summer programs to choose from, you can earn college credit, discover a new subject area, perform cutting-edge research in university labs, or immerse yourself in hands-on learning.Academic lifeSPP invites you to join other highly motivated teens from 87 countries in our summer programs for high school students — and take the leap into college life and academics, which enables you to take on new academic challenges, explore a variety of interests and consider possible majors. You can take college courses alongside undergraduates either on campus or online. And you can also earn up to eight college credits by conducting in-depth STEM research with individual instructors or as part of a group project. Or, you can immerse yourself in a variety of stimulating noncredit seminars that blend lectures with experiential learning, discussions, and projects.Campus/Residence lifeEmbracing college life is an exciting experience. Whether you live on campus or commute, you’ll get to know the ins and outs of college and city life.

Resident program assistants provide guidance, coordinate and lead social activities, ranging from group activities that include comedy shows to field trips.Your hard work will be combined with social events and fun activities —and you’ll still have time for your own adventures on campus! Email the SPP office at ******************.1. What does SPP aim to do?A．To help college students to achieve academic success.B．To provide admission guidelines for pre-college students.C．To get high school students well-prepared for college life.D．To encourage students to participate in hands-on learning.2. What are students supposed to do to earn the required credits?A．Carry out STEM research. B．Attend various seminars.C．Finish the courses online. D．Join in experiential learning.3. What can we know about students living on campus?A．They can organize social activities. B．They will have access to a single room.C．They are provided with good security. D．They are advised to direct comedy shows.“I can’t connect with your characters.”I kept hearing the same feedback and was unable to understand why and not sure what to do. I was a character-driven writer. How could I mess up the one thing I was supposed to be good at? I was determined to convince my agent that these characters were real. After all, I knew they were real. My main character Lotus had lived inside me for years. I just needed to clarify her on the page.I wrote and edited for a year, trying to respond to this agent’s feedback. But Lotus’ personality began to disappear. I tried to have her make “better” decisions, wear smarter fashion, and have more friends, as my agent said she acted “immature” and was “isolated”. And when this agent ultimately parted ways with me, I felt like I had failed. Now with time and distance, I realize I tried to fit Lotus into a neurotypical style to please my agent. And as a result, Lotus lost her Lotus-ness.When that agent discouraged me from writing Lotus as autistic(自闭的), he said that would make Lotus seem more “vulnerable(脆弱的)” or an “obvious victim”. I didn’t want Lotus to seem vulnerable. Lotus’ autism is what makes her powerful, I tried to explain. But from a neurotypical perspective, Lotus’ autism could only be seen as a weakness.Unsure of how to convince my agent of the strength and power autistic women hold, I began to write Lotus as “neurotypical”. And I failed miserably. After all, what do I know about being neurotypical? My whole life, autism was my default. Not being diagnosed until 2020, I assumed the way I saw the world was “normal”.My current agent encourages me to write from my neurodivergent(神经多样性的) experience. With this invitation, I revisited Lotus and saw her the way I first wrote her. And when I did, the characters and the entire narrative began to make more sense.Identifying my characters as neurodivergent not only gives me joy as a writer, but it has produced my strongest writing. For so long, I’ve combatted the advice to “write what I know”, in part because I didn’t know what I actually knew. I didn’t know I was neurodivergent. But a s I mine the specificity of my lived experience, my writing is stronger. There is a power to our lived experience. It’s not a limitation on our craft, but a swinging open of the gates.4. How did the author feel when receiving the repeated response from the first agent?A．Confused. B．Convinced. C．Determined. D．Disappointed. 5. Lotus’ personality got lost because ______A．Lotus no longer lived inside the author B．the author attempted to please the agent C．the agent failed to sympathize with Lotus D．Lotus was considered childish and lonely 6. What do we know about the author?A．She regretted parting with the agent.B．She owed her success in life to autism.C．She was aware of her autism in the early years.D．She was empowered by her autistic experience.7. What has the author learned from her own experience?A．Stick to your dream despite discouragement.B．Be true to yourself and write from your heart.C．Giving in to authority is the barrier to success.D．Everyone is born an original instead of a copy.At one time, the inheritance of traditional drama was difficult. People of insight screamed “save drama”. Many celebrities and big names put down their figures and went to the community to carry out public welfare performances of opera, and did everything possible to expand the coverage of drama. In recent years, traditional Chinese culture and art has gained a foothold on short video platforms and attracted a large number of young followers thanks to the explosive growth of the short video industry. Relaxing, emotional and fragmented, these video contents perfectly match the demands of the users. With the application of new technologies such as social communication and immersive experiencing, short video platforms are seeing more users, becoming a shining spot of new Internet media.Recently, Huangmei Opera “ Female Consort Prince ” became a hit on short video platforms as a lot of young users covered the aria (咏叹调) in their own way and showed great artistic talents. The interactive platforms are expanding the charm of the traditional opera among young people.Peking Opera was also well-received on short video platforms thanks to a series of augmented reality (AR) effects. Users love to film clips with a set of virtual facial makeup, headwear and costumes. Statistics indicate that these effects were applied by more than 18 million users, most of whom were young people.In addition to Chinese operas, intangible cultural heritage items, such as embroidery, paper-cutting, printing and dyeing, shadow play works, oiled paper umbrella making, and bamboo weaving are also actively promoted on short video platforms. In a word, short video platforms are becoming an important channel to display China’s intangible cultural heritage.Short video platforms, offering a fun, popular and easy way to explore the traditional art forms, are receiving a lot of positive feedbacks from China’s young generations. The seconds, or minutes long videos, along with unlimited possibilities as well as richness of styles, have produced remarkable achievements in promoting traditional Chinese culture.8. What mainly made the inheritance of traditional drama difficult?A．The slow growth of industry. B．The insufficient coverage of drama.C．The poorly-met demands of the users. D．The severe shortage of the drama actors.9. What led to the promotion of Peking Opera on short video platform?A．The social communication. B．The set of virtual facial makeup.C．The positive feedbacks from users. D．The application of new technologies.10. Why are paper-cutting and bamboo weaving mentioned?A．To expand the charm of traditional Chinese culture.B．To prove traditional art forms are actively promoted.C．To show the current situation of these cultural heritage.D．To offer new channels to display China’s cultural heritage.11. Which of the following is the best title for the text?A．The Bright Future of Huangmei Opera.B．The Explosive Growth of the Short Video Industry.C．The Simple Way to Explore the Traditional Art Form.D．The Creative Combination of Culture and Technologies.Several years ago, Jeremy Clarkson, presenter of the famous BBC television programme “Top Gear” discovered that one of his guests was half German and half Irish. Immediately, he said: “That's quite a strange combination. It's like, this must be done absolutely perfectly... tomorrow”.This joke played on stereotypes (刻板印象) of the Germans as efficient and the Irish as lazy. Many people could understandably be offended by these kinds of assertions (断言).We do not know every Irish person, so how can we then conclude that every Irish person is lazy?I recently read on a website that Irish business people were described as being 'generally rather casual' and more outwardly friendly than many European counties'. German business people, on the other hand, are considered to be very direct and according to the website, they do not need a personal relationship in order to do business. Once you hear advice like this,it becomes easier to understand where jokes like the one in the first paragraph come from.So why do some people disapprove of the kind of stereotypes as seen in Clarkson's joke, but not baring an eyelid (眨眼) when it comes to generalizations. What is the difference between the two?By definition, a stereotype is a widely held but fixed and oversimplified image or idea of a particular type of person or thing. A cultural characteristic, on the other hand, is a pattern of behaviour that is typical of a certain group.So what does this really mean? Stereotype are simply overstated assumptions about groups of people. Imagine if a tourist visited a small town in Switzerland and saw a number of locals playing the alphorn instrument, and then claimed that Swiss people can play the alphorn. This would be a stereotype! This is an overstated image of the Swiss which is based on one tourist's experience.If however, this tourist were to say that the Swiss are very punctual, this could be seen as a cultural characteristic. This is because it is a pattern of behaviour which is very typical in Switzerland: fromtheir transport system to their business meetings in this way, some people argue that generalizing another culture is not just useful. but important. Politicians always have to be mindful of the cultural characteristics of different countries. By becoming aware of different cultural characteristics,they can avoid causing offence (冒犯) in those cultures.However, others argue that generalizing cultures will always lead to offensive stereotypes. They argue that the best thing we can do is to stop generalizing cultures and start treating people as individuals.All this raises important questions: can making generalizations about groups of people be a positive thing? Or should we always avoid making broad assumptions about different groups?12. Whe n he said, “it's like, this must be done absolutely perfectly... tomorrow”，Jeremy Clarkson really meant________.A．the stereotypes of the Germans and the Irish are not so goodB．the combination of half German and half Irish is interestingC．the characteristics of the Germans and the Irish are oppositeD．the Germans will do it perfectly tomorrow while the Irish won't13. Which of the following is TRUE according to the passage?A．It's typical of the Swiss to be punctual.B．The Swiss can play the alphorn quite well.C．The Irish people are considered as lazy, direct and casual.D．The Germans are thought to be efficient, friendly and direct.14. Politicians think it important to generalize another culture because________.A．they don't want to offend other peopleB．generalizing will lead to offensive stereotypesC．cultural characteristics are better than stereotypesD．they think different cultural characteristics are useful15. The main purpose of this passage is to________.A．illustrate the importance of making generalizationsB．show it is wrong to play jokes on stereotypes of different peopleC．tell us the differences between stereotypes and cultural characteristicsD．discuss whether it is good to make generalizations about groups of people“Just think positively!”“It could be worse.”“You should look at the bright side!”We’ve all heard (and maybe used) these phrases without much thought. But they could be contributing to a culture of toxic(有毒的) positivity. For those new to this term, it might sound like an oxymoron(矛盾修辞法). How can positivity be toxic? Isn’t it supposed to be helpful, or “positive”, as the name suggests? 16“Toxic positivity is when somebody avoids all negative thoughts or feelings, pretending everything is going well when it is not,” explains Melissa Dowd, a therapist at PlushCare, a virtual health platform for primary care and mental health services.Whitney Goodman, the author of Toxic Positivity describes toxic positivity as the “endless pressure to be happy and pos itive, no matter what the circumstances are.” 17 It’s also something we can cause other people to experience. Expressing toxic positivity to others may look like offering them a simple solution to a complicated problem that we know nothing about, or not allowing people around you to appropriately express negative emotions.Toxic positivity causes us to suppress our emotions, which can make them worse. 18 “Although it can be helpful to look on the bright side when facing challenges,” Dowd says, “not copi ng with negative feelings in a healthy way in the moment can lead to those feelings resurfacing later in different areas of your life or as a form of anxiety.” 19 “If I feel like you’re going to dismiss me, I’m going to stop sharing how I’m feeling,” Goo dman adds.20 If you’re using toxic positivity against yourself, Goodman suggests remembering it’s OK if you’re upset about something. It’s valid if something annoys you. “Allow ourselves and other people to share when they’re going through a difficult time,” she says. Dowd adds that it’s essential that “we all learn to cope with and process our emotions in a healthy way as opposed to avoiding how we feel” as life’s stressors continue to rise. For example, instead of simply saying “Just think positively,”we’d better say “Sometimes bad things happen. How can I help?”This Too Shall PassWhen my family moved to Ohio over the summer, I feared attending another new school and knowing no one because I was able to expect what was coming. I had bright red hair and enormous glasses. In addition, I was_______and not very sociable.Boarding the school bus that first day, I felt like all eyes on me. I could hear the_______“She’s huge!” Obviously, the kids on the bus had known each other well. I spent that first bu s_______in silence.The following day was even_______. I did not notice that a few boys had tied a shoelace across the aisle and thus fell face first on the bus, _________everything I was carrying. _________I was embarrassingly gathering my supplies, I cou ld hear the laughter, and then the_______“That felt like an earthquake!” Anyway, I_______ to find a seat. Looking out of the window, I_______the tears welling up in my eyes.It was then that I sank into myself. I began walking everywhere. I would wander through the woods behind our house. I would also walk to a________about two miles down the road, where I would chat silently with myself. I began________the afternoon school bus on purpose, walking home instead. Then,________, I started losing weight. And as I became content with myself, I began making________.One of my newly-found friends also________with her weight, wanting to be a “perfect” cheerleader. She lived near my neighborhood so we would meet and________together. This became a daily activity with talking and laughing________the way—different from the lonely walks I had taken. My friend said that I didn’t have to be perfect. I just had to be me, and be happy with________. While I would not want to________that time of loneliness, sadness and embarrassment, Iam________I made it through. Whenever I am struggling with any other problem in life, I always remember the proverb “This too shall pass.” If you can find a path with no obstacles, it probably doesn’t________anywhere.21.A．outgoing B．overweight C．intelligent D．friendly22.A．whisper B．whistle C．giggle D．laugh23.A．drive B．lift C．ride D．travel24.A．worse B．longer C．funnier D．duller25.A．throwing B．losing C．leaving D．dropping26.A．Though B．While C．Since D．Because27.A．opinions B．statements C．comments D．discussions28.A．determined B．attempted C．pretended D．managed29.A．kept away B．took back C．put away D．held back30.A．garden B．market C．church D．library31.A．escaping B．missing C．delaying D．stopping32.A．uninterestedly B．uncertainly C．unfortunately D．unexpectedly 33.A．changes B．friends C．efforts D．decisions34.A．struggled B．competed C．dealt D．lived35.A．run B．play C．chat D．walk36.A．along B．across C．by D．in37.A．oneself B．myself C．herself D．itself38.A．relive B．remind C．relate D．rethink39.A．excited B．upset C．proud D．regretful40.A．exist B．stretch C．lead D．stay阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

四川省成都市第七中学2024-2025学年高三上学期10月月考语文试题含答案
2024～2025学年度上期高2025届10月阶段性测试语文试题考试时间：150分钟满分：150分一、现代文阅读（33分）（一）现代文阅读Ⅰ(本题共5小题，17分)阅读下面的文字，完成1～5题。
材料一：陈国栋同志的报告是一个重要文件。
请各大区区长主持讨论，细致地讨论，讨论两次至三次。
我基本上同意这个文件所述的意见。
但觉：（一）假定今年年成比去年确实好的情况之下，征购一千一百亿斤，力争办到，这是变被动为主动的第一着。
今年年成如果在秋收以后确实较去年好，确实证明无妄的时候，为什么不能征购到这个数目字呢？（二）下年度销售计划，我感觉不但一千另二十亿斤，是太多了，这个文件上调整为八百五十五亿斤，似乎也略为多了一点。
是否可以调整为八百亿斤，或者八百一十、二十亿呢？告诉农民，恢复糠菜半年粮，可不可以呢？苦一年、两年、三年，就翻过身来了。
多储备，少食用，以人定量，粮食归户……忙时多吃，闲时少吃，有稀有干，粮菜混吃，仍然可以吃饱吃好，可不可以这样做呢？（三）多产粮，是上策。
田头地角，零星土地，谁种谁收，不征不购，主要为了解决饲料，部分为了人用。
恢复私人菜园，一定要酌给自留地。
凡此种种，可以多收。
既已多收，可以多吃（例如菜）。
（四）好好地精细地安排过日子。
是否可以按照一九五七年的实际产量安排过日子呢？一九五七年的日子不是过得还不错吗？这样做，农民的粮食储备就可以增得较多了。
手里有粮，心里不慌，脚踏实地，喜气洋洋。
……以上几点意见，只供同志们此次讨论的参考，切勿下传。
不对之处，准备修改。
（摘自毛泽东《粮食问题》）【注】材料一是毛泽东于一九五九年七月五日为印发粮食部副部长陈国栋关于一九五九至一九六零年度粮食分配和粮食收支计划调整意见的报告写的批语，题目是毛泽东拟的。
此前毛泽东曾批示：“按人定量，忙时多吃，闲时少吃，忙时吃干，闲时半干半稀，杂以番薯、青菜、萝卜、瓜豆、芋头之类。
”材料二：一个国家唯有立足粮食基本自给，才能掌握粮食安全的主动权，才能保障国运民生。
