正确；且f（x）在（﹣1，﹣）递增，在（﹣，0）递减，故B错误；当x≥0时，f（x）＝x﹣x2＞0，解得0＜x＜1；当x＜0时，f（x）＝﹣x﹣x2＞0，解得﹣1＜x＜0，所以f（x）＞0的解集为（﹣1，0）∪（0，1），故C错误；当x≥0时，f（x）+2x＝3x﹣x2≥0，解得0≤x≤3；当x＜0时，f（x）+2x＝x﹣x2≥0，解得x∈∅．所以f（x）+2x≥0的解集为[0，3]，故D正确．故选：AD．【点评】本题考查函数的奇偶性和单调性的判断和运用，考查转化思想和运算能力、推理能力，属于中档题．三、填空题（本大题共4小题，每小题5分，共20分）11．（5分）已知集合A＝{x|ax+1＝0}，B＝{﹣1，1}，若A∩B＝A，则实数a的所有可能取值的集合为{﹣1，0，1}．【分析】根据题中条件：“A∩B＝A”，得到B是A的子集，故集合B可能是∅或B＝{﹣1}，或{1}，由此得出方程ax+1＝0无解或只有一个解x＝1或x＝﹣1．从而得出a的值即可【解答】解：由于A∩B＝A，∴A＝∅或A＝{﹣1}，或{1}，∴a＝0或a＝1或a＝﹣1，∴实数a的所有可能取值的集合为{﹣1，0，1}故答案为：{﹣1，0，1}【点评】本题主要考查了集合的包含关系判断及应用，方程的根的概念等基本知识，考查了分类讨论的思想方法，属于基础题12．（5分）函数f（x）＝的定义域是（﹣∞，1）．【分析】根据二次根式的性质和分式的意义，被开方数大于等于0，分母不等于0，就可以求解．【解答】解：依题意，得1﹣x＞0，解得x＜1，∴函数的定义域是（﹣∞，1）故答案为：（﹣∞，1）．【点评】本题考查了函数自变量的取值范围：注意分式有意义，分母不为0；二次根式的被开方数是非负数．13．（5分）函数y＝|x2﹣4x|的单调减区间为（﹣∞，0），（2，4）．【分析】画出函数y＝|x2﹣4x|的图象，利用图象写出单调区间．【解答】解：画出函数y＝|x2﹣4x|的图象，由图象得单调减区间为：（﹣∞，0），（2，4）故答案为：（﹣∞，0），（2，4）【点评】本题考查了函数的单调性，画出图象是关键，属于基础题．14．（5分）定义在R上的奇函数f（x），满足x＞0时，f（x）＝x（1﹣x），则当x≤0时，f （x）＝x（x+1）．【分析】根据题意，由奇函数的性质可得f（0）＝0，设x＜0，则﹣x＞0，由函数的奇偶性和解析式可得f（x）＝﹣f（﹣x）＝x（x+1），综合2种情况即可得答案．【解答】解：根据题意，f（x）为定义在R上的奇函数，则f（0）＝0，设x＜0，则﹣x＞0，则f（﹣x）＝（﹣x）（1+x），又由函数为奇函数，则f（x）＝﹣f（﹣x）＝x（x+1），综合可得：当x≤0时，f（x）＝x（x+1）；故答案为：x（x+1）【点评】本题考查函数的奇偶性的性质以及应用，注意f（0）＝0，属于基础题．四、解答题（本大题共3小题，共38分）15．（10分）已知集合A＝{x|x2﹣4＞0}，B＝{x|2x2+x﹣6＞0}，求A∪（∁R

江苏省南师附中2020-2021学年高一上学期10月月考英语试卷第一部分: 阅读理解 (共两节，满分 26 分)第一节: 阅读短文 (共 8 小题; 每小题 2 分，满分 16 分)请认真阅读下列短文，从短文后各题所给的 A、B、C、D 四个选项中，选出最佳选项。

AThe clothes you wear. The food you eat. The color of your bedroom walls. Where you go and how you get there. The people you hang around with. What time you go to bed. What do these things have in common? You’re asking. They’re just a few examples of many hundreds of things that your parents controlled for you when you were a child.As a kid, you didn’t have a say in very much that went on; your parents made decisions about everything from the cereal you ate in the morning to the pajamas you wore at night. And it’s a good thing, too-kids need this kind of protection and assistance bec ause they aren’t mature enough to take care of themselves and make careful decisions on their own.But finally, kids grow up and become teens. And part of being a teen is developing your own identity (身份认同)---one that is separate from your parents’. But as you change and grow into this new person who makes your owndecisions, your parents have a difficult time adjusting (调整). They aren’t used to the new you yet --- they only know you as the kid who had everything decided for you and didn’t mind.In many families, it is this adjustment that can cause a lot of fighting between teens and parents. And issues like the type of friends you have or your attitudes to partying can cause bigger quarrels, because your parents still always want to protect you and keep you safe, no matter how old you are.The good news about fighting with your parents is that in many families the arguing will lessen as parents get more comfortable with the idea that their teen has a right to certain opinions. It can take several years for parents andteens to adjust to their new roles, though. In the meantime, focus on communicating with your parents.Sometimes this can feel impossible --- like they just don’t see your point of view and never will. But talking and expressing your opinions can help you gain more respect from your parents and you may be able to reach compromises (和解) that make everyone happy. For example, if you are willing to clean your room in order to stay out an hour later, both you and your parents walk away with a good deal. Keep in mind, too, that your parents were teens once and that in most cases, they can relate to what you’re going through.1.In Paragraph2. the author .plains that parents control kids too muchB.proves that kids have no right to give their opinionsC.describes how carefully parents look after kidsD.explains parents control kids for protection and assistance2.A lot of fighting breaks out between teens and parents because .A.parents aren’t used to losing control of kidsB.teens like to have everything decided for themC.parents get angry at teens not respecting themD.teens are eager to develop their own identity3.In the author’s opinion, parents control teens in order to .A.prevent them from having their own ideasB.protect them from being hurtC.make them respect parents in the familyD.make sure that children have a good future4.Which of the following teenagers’ questions does the author try to answer?A.What do parents control their children for?B.When do parents take care of their children?C.How do I get rid of my parents’ control?D.Why do I fight with my parents so much?BWhen I was 16 years old and in foster care (寄养中心) in Tennessee, I wanted a family very much. I asked for the help of a judge, even the commissioner of the Department of Children’s Services, and was adopted (收养) just a week before my 18th birthday.We have a lot to be grateful for and this holiday season let’s not forget about the more than 415,000 youth in foster care especially older youth These youth are the most likely to get overlooked ( 忽视 ) for adoption, but they shouldn’t be. They need and dese rve a family just as much as young children do. Making an older youth a part of your family can bring just as much a joy as adopting a baby or a younger child.My adoption was life changing and probably the best thing that ever happened to me. I still remember the first gift my parents gave to me. It was a Mickey Mouse key chain with a key to their home. They told me that no matter what happened they would always love me and I’d always have a place to come home to. This is our 17th Thanksgiving together....My first Thanksgiving with my family was a little overwhelming (难以应付的) with lots of extended family including grandparents, aunts, uncles, and cousins. However, It’s when I realized that I would never have to spend another holiday alone and that was truly an amazing feeling.I was always eager to spend time with my little sister, Beth. She was six when I joined the family. My dad always says he knew we were really sisters, and I was no longer a guest in the house when Beth and I had our first fight. Today, she’s one of my best friends, and I’m her biggest cheerleader.There were also bittersweet Thanksgivings. One we spent in my mom’s hospital ro om. It was there that she helped me plan my wedding but passed away three weeks before the ceremony. My dad walked me down the aisle, and my sister was my maid of honor. Because of our bond, we were able to support each other through thatc hallenging time and that’s what family is for the good and bad times.It’s nice having my dad and sister to share holidays and special occasions. But they’re even more important when it comes to the little things -like having someone to share my bad day with, celebrate my achievements at work, or help me think through a difficult decision. It’s in these moments that I just can’t imagine being alone in the world.I’m so glad that I didn’t listen to those people who said I’d never find a family, and that I was putting myself out there for rejection (拒绝接受). It’s a risk for older foster youth to consider adoption. It’s an opportunity to be rejected once again. But it’s a risk they should take because life doesn’t end at 18. It’s really just beginning.If you know someone who might consider adopting an older teen, please share my story --- and have him or her think of my family. They didn’t get to see my first steps. But they taught me so many things about life, and were there to watch me walk across the stage when I graduated from college and law school and accompanied (陪伴) me to the White House last year as I was honored for my work helping foster youth.I look forward to many more Thanksgivings with my family, and I’m thankful they chose me to be a part of their family.5.What can we learn from the author’s personal experiences?A.It’s rather difficult for older youth to be adopted.B.Older youth bring less joy than babies.C.It’s unforgettable to have bittersweet Thanksgivings.D.An older youth aged 18 is too old to need a family.6.What makes the author feel that she can’t imagine being alone in the world?A.The family’s giving her a Mickey Mouse as a gift.B.The family’s always sharing happiness and sorrow with her.C.Her mother’s failing to attend her wedding.D.Spending Thanksgiving with her extended family for years.7.According to the author, adoption really means for older youth.A.not living alone any longerB.being taken good care of by othersC.being successful in careerD.being loved and accepted8.What is the author’s main purpose of writing the passage?A.To express her love for her family.B.To feel sorry for the unadoptable older youth.C.To ask more people to adopt the older youth.D.To tell the readers not to blindly believe others.第二节: 七选五(共 5 小题: 每小题 2 分，满分 10 分)阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

江苏省南京师范大学附属中学2024-2025学年高一上学期10月月考英语试卷一、阅读理解We all remember that first cry at the movies. Whether they are tears of joy or sadness, it’s quite astonishing that human emotion can be controlled by moving images on a screen. In fact, it all comes from a plan. But what about those heart-breaking stories… for kids? They seem not to sugarcoat the realities of the world.Actually, many great kids’ movies loaded with tragedy (悲剧) are purposefully meant to stir up kids’ strong feelings. According to Aristotle, tragedy aids us in facing life’s unsolvable issues through sensible thought. Therefore, the existence of tragedy in kids’ movies is to teach kids to handle, to understand and to heal (治愈). The hardest lesson for a child is how to deal with loss, especially if it’s sudden. The cartoon classic The Lion King tells the story of Simba, who experiences the loss of his father. Kids see themselves in Simba’s character. He has dreams. He has a desire to grow and be a part of a bigger world. But it is really heartbreaking to see the loss.Why is a film like this so beloved when it makes kids cry? The lesson it teaches is to overcome hardships and to move forward. Hakuna Matata! Yes, the phrase from The Lion King is to teach kids it’s okay to move on from tragic loss and not to let it define you. It’s an important lesson we learned at a very young age. Sadness should not be ignored. It’s important to feel sad, and that is why these films are so great. In Dumbo, Charlotte’s Web and Bridge to Terabithia, we lose our beloved characters. This quite upsets kids, but it teaches them to accept sadness and makes something new out of it.So, what is the message behind a sad kids’ movie? It’s meant to teach the audience, especially children, to gain their independence and how to free themselves from tragedy. It’s like a cushion (缓冲垫) that separates stories from reality. It helps children deal with sad feelings when they come for real, or at least find relief by saying Hakuna Matata.1．Why does the author mention “first cry” in paragraph 1?A．To promote a movie.B．To explain the reason.C．To support an argument.D．To introduce the topic.2．What does the underlined phrase “Hakun a Matata” in paragraph 3 mean?A．Defining sadness as a treatment.B．Challenging oneself with tragic losses.C．Seeking knowledge to enrich life.D．Heading forward without being trapped.3．What can we learn from the last paragraph?A．Sad kids’ movies help children to escape from reality.B．Sad kids’ movies prepare children for life struggles.C．Children can learn to ignore sadness in tragedy.D．Children can find a way to hide sad feelings.4．What is the best title for the text?A．Why Are Great Kids’ Movies So Sad?B．What Is the Power of Great Kids’ Movies?C．Life’s Hardest Lesson: How Movies Inspire Us?D．Moving Beyond Reality: What Kids’ Movies Teach Us?Is future you? It might seem like a strange philosophical question. But the answer to how you think about your future self could make the difference between decisions you ultimately find satisfying and ones you might eventually regret.The brain patterns that emerge on an MRI (核磁共振成像) when people think about their future selves most like the brain patterns that arise when they think about strangers. This finding suggests that, in the mind’s eye, our future selves look like other people. If you see future you as a different person, why should you save money, eat healthier or exercise more regularly to benefit that stranger?However, if you see the interests of your distant self as more like those of your present self, you are considerably more likely to do things today that benefit you tomorrow. A paper in the journal PLoS One revealed that college students who experienced a greater sense of connection and similarity to their future selves were more likely to achieve academic success. Relationships with our future selves also matter for general psychological well-being. In a project led by Joseph Reiff, which includes 5, 000 adults aged 20 to 75, he found that those who perceived a greatoverlap (重叠) in qualities between their current and future selves ended up being more satisfied with their lives 10 years after filling out the initial survey.So how can we better befriend our future selves and feel more connected to their fates? The psychological mindset with what we call ”vividness interventions“ works. We have found, for instance, that showing people images of their older, grayer selves increases intentions to save for the long term. Besides, you might try writing a letter to-and then from-your future self. As demonstrated by Yuta Chishima and Anne Wilson in their 2020 study in the journal Self and Identity, when high-school students engaged in this type of ”send-and-reply“ exercise, they experienced elevated (升高的) levels of feelings of similarity with their future selves.Letter-writing and visualization exercises are just a couple of ways we can connect with our future selves and beyond, but the larger lesson here is clear: If we can treat our distant selves as if they are people we love, care about and want to support, we can start making choices for them that improve our lives-both today and tomorrow.5．What’s the function of paragraph 2?A．Generating further discussion.B．Introducing a research result.C．Showing the effect of the finding.D．Concluding various viewpoints.6．How does the author prove his statements?A．By offering relevant statistics.B．By using quotations.C．By referring to previous findings.D．By making comparisons.7．What is paragraph 4 mainly about?A．Benefits of befriending our future selves.B．Ways of connecting with our future selves.C．Methods of changing psychological mindsets.D．Possibilities of us becoming our future selves.8．What does the article want to tell us?A．Making future plans makes a difference.B．Our future selves look like other people.C．Getting to know your future self benefits.D．Your choice affects the fates of strangers.Robotic comedyIt seems you can ask artificial intelligence (AI) programs anything, and they’ll give you an answer back. So, can they tell jokes? This question was raised when UK comedian Karen Hobbs performed in late June. Instead of the usual jokes she created, Hobbs told jokes written by ChatGPT. 9 .Hobbs said that when she asked ChatGPT for a joke, what it provided was a man joking about being impatient with his shopping-obsessed (痴迷于购物的) girlfriend. 10 , the joke was still about a shopping-obsessed girlfriend, just told from the first-person perspective (角度).11 , as males dominate the field of comedy. The BBC commented that AI storytelling can only reproduce information that already exists in some form, although it can produce some never-before-seen combinations (结合) of ideas. “One way that AI can tell jokes is to do what any 5-year-old does — repeat a successful joke they’ve heard or try to make an obvious variation (变化) of it,” said Les Carr, a professor of web science.Nonetheless, a good joke in real life can always adjust to the audience’s feedback, which often leads comedians to improvise (即兴创作). 12 . For instance, in improv, there is no space for premeditation (预先策划); the comedian must rely only on their instinctive (直觉的) reaction to the audience.“A well-done stand-up bit can lead the audience through a funny story all the way to a hilarious punchline (令人捧腹的妙语),” Michael Ryan, a student researching AI’s impact on comedy, explained to the BBC．“The whole time the comedian knew exactly where he or she was going with the joke and brought the audience there.”13 . Research is already ongoing with the goal of giving AI a greater understanding of the world around it, which makes the future of AI jokes still uncertain.A．The process made her nervousB．However, this could all changeC．It’s certain that AI can become genuinely funnyD．Even when she asked to switch to the woman’s perspectiveE．This, unfortunately, is beyond the current capabilities of AIF．She could thus finish the job more efficiently and creativelyG．It’s no surprise that many jokes come from a male perspective in online materials二、完形填空A young man Jermaine Scott set up in business as a barber in Madison, Tennessee, about a year ago. He gradually found the kids were addicted(上瘾)to tablets and 14 products when they came to the barbershop. It was extremely 15 to cut their hair when they were focused on those, and kids would feel cross and lack passion(激情)for life if they play cell phones for a long time. That led to the 16 of Scott’s “Barbershop Books Day”, when kids could come and get a 17 haircut. What was required? They are only required to 18 a book while they got it.He created “Barbershop Books Day” to help not only the kids, but also the worried parents. Madison has many 19 families and many are entirely focused on just keeping their lights on. Many parents are busy with their work and barely have time to keep their children 20 . For people in this community,$15 for a haircut per kid is not easy to 21 , so in some way a reduction(减少)in the price can 22 .Scott began his 23 by borrowing five books from City Library and putting them near his chair. Book 24 began flooding in when a local news station broadcast what he was doing. Scott plans on taking it a step further by expanding his “Barbershop Books Day” to an “Ice Breaker Book Tour” where he 25 to get kids excited and inspired to learn while also giving them 26 role models through inspiring speakers so as to encourage them. Scott said, “If I step out of my comfort zone, challenge myself and instill(灌输)in them the idea that school is cool and educational, 27 it will guide them in the right direction.” He also emphasized that it’s up to all the members of the society to develop students’ lifelong 28 for reading.14．A．scientific B．quality C．software D．electronic 15．A．safe B．hard C．possible D．pleasant 16．A．advertisement B．support C．celebration D．birth 17．A．high- quality B．lower- priced C．cool D．free 18．A．borrow B．buy C．read D．choose19．A．low- income B．middle- class C．modern D．large 20．A．home B．secure C．company D．informed 21．A．neglect B．afford C．believe D．fall 22．A．arise B．succeed C．count D．advance 23．A．travel B．principle C．lesson D．program 24．A．sellers B．lists C．orders D．donations 25．A．agrees B．intends C．needs D．proves 26．A．typical B．classical C．positive D．passive 27．A．hopefully B．simply C．fortunately D．normally 28．A．passion B．activity C．plan D．taste三、单词拼写29．Stephen Hawking s bravely against his illness throughout his life.

江苏省南京市南京师范大学附属中学2020-2021学年高一上学期10月月考英语试卷第一部分:阅读理解(共两节，满分26分)第一节:阅读短文(共8小题;每小题2分，满分16分)请认真阅读下列短文，从短文后各题所给的A、B、C、D四个选项中，选出最佳选项。

AThe clothes you wear.The food you eat.The color of your bedroom walls.Where you go and how you get there.The people you hang around with.What time you go to bed.What do these things have in common?You’re asking.They’re just a few examples of many hundreds of things that your parents controlled for you when you were a child.As a kid,you didn’t have a say in very much that went on;your parents made decisions about everything fromthe cereal you ate in the morning to the pajamas you wore at night.And it’s a good thing,too-kids need this kind ofprotection and assistance because they aren’t mature enough to take care of themselves and make careful decisionson their own.But finally,kids grow up and become teens.And part of being a teen is developing your own identity(身份认同)---one that is separate from your parents’.But as you change and grow into this new person who makes your owndecisions,your parents have a difficult time adjusting(调整).They aren’t used to the new you yet---they only knowyou as the kid who had everything decided for you and didn’t mind.In many families,it is this adjustment that can cause a lot of fighting between teens and parents.And issues likethe type of friends you have or your attitudes to partying can cause bigger quarrels,because your parents still alwayswant to protect you and keep you safe,no matter how old you are.The good news about fighting with your parents is that in many families the arguing will lessen as parents getmore comfortable with the idea that their teen has a right to certain opinions.It can take several years for parents andteens to adjust to their new roles,though.In the meantime,focus on communicating with your parents.Sometimes this can feel impossible---like they just don’t see your point of view and never will.But talking andexpressing your opinions can help you gain more respect from your parents and you may be able to reachcompromises(和解)that make everyone happy.For example,if you are willing to clean your room in order to stayout an hour later,both you and your parents walk away with a good deal.Keep in mind,too,that your parents wereteens once and that in most cases,they can relate to what you’re going through.1.In Paragraph2.the author______.plains that parents control kids too muchB.proves that kids have no right to give their opinionsC.describes how carefully parents look after kidsD.explains parents control kids for protection and assistance2.A lot of fighting breaks out between teens and parents because______.B.teens like to have everything decided for themC.parents get angry at teens not respecting themD.teens are eager to develop their own identity3.In the author’s opinion,parents control teens in order to______.A.prevent them from having their own ideasB.protect them from being hurtC.make them respect parents in the familyD.make sure that children have a good future4.Which of the following teenagers’questions does the author try to answer?A.What do parents control their children for?B.When do parents take care of their children?C.How do I get rid of my parents’control?D.Why do I fight with my parents so much?BWhen I was16years old and in foster care(寄养中心)in Tennessee,I wanted a family very much.I asked forthe help of a judge,even the commissioner of the Department of Children’s Services,and was adopted(收养)just aweek before my18th birthday.We have a lot to be grateful for and this holiday season let’s not forget about the more than415,000youth in foster care especially older youth These youth are the most likely to get overlooked(忽视)for adoption,but theyshouldn’t be.They need and deserve a family just as much as young children do.Making an older youth a part ofyour family can bring just as much a joy as adopting a baby or a younger child.My adoption was life changing and probably the best thing that ever happened to me.I still remember the first gift my parents gave to me.It was a Mickey Mouse key chain with a key to their home.They told me that no matterwhat happened they would always love me and I’d always have a place to come home to.This is our17th Thanksgiving together....My first Thanksgiving with my family was a little overwhelming(难以应付的)with lots of extended family including grandparents,aunts,uncles,and cousins.However,It’s when I realized that I would never have to spendanother holiday alone and that was truly an amazing feeling.I was always eager to spend time with my little sister,Beth.She was six when I joined the family.My dad always says he knew we were really sisters,and I was no longer a guest in the house when Beth and I had our first fight.Today,she’s one of my best friends,and I’m her biggest cheerleader.There were also bittersweet Thanksgivings.One we spent in my mom’s hospital room.It was there that she helped me plan my wedding but passed away three weeks before the ceremony.My dad walked me down the aisle,and my sister was my maid of honor.Because of our bond,we were able to support each other through thatchallenging time and that’s what family is for the good and bad times.It’s nice having my dad and sister to share holidays and special occasions.But they’re even more important when it comes to the little things-like having someone to share my bad day with,celebrate my achievements at work,or help me think through a difficult decision.It’s in these moments that I just can’t imagine being alone in the world.I’m so glad that I didn’t listen to those people who said I’d never find a family,and that I was putting myselfout there for rejection(拒绝接受).It’s a risk for older foster youth to consider adoption.It’s an opportunity to berejected once again.But it’s a risk they should take because life doesn’t end at18.It’s really just beginning.If you know someone who might consider adopting an older teen,please share my story---and have him or herthink of my family.They didn’t get to see my first steps.But they taught me so many things about life,and werethere to watch me walk across the stage when I graduated from college and law school and accompanied(陪伴)meto the White House last year as I was honored for my work helping foster youth.I look forward to many more Thanksgivings with my family,and I’m thankful they chose me to be a part of their family.5.What can we learn from the author’s personal experiences?A.It’s rather difficult for older youth to be adopted.B.Older youth bring less joy than babies.C.It’s unforgettable to have bittersweet Thanksgivings.D.An older youth aged18is too old to need a family.6.What makes the author feel that she can’t imagine being alone in the world?A.The family’s giving her a Mickey Mouse as a gift.B.The family’s always sharing happiness and sorrow with her.C.Her mother’s failing to attend her wedding.D.Spending Thanksgiving with her extended family for years.7.According to the author,adoption really means______for older youth.A.not living alone any longerB.being taken good care of by othersC.being successful in careerD.being loved and accepted8.What is the author’s main purpose of writing the passage?A.To express her love for her family.B.To feel sorry for the unadoptable older youth.C.To ask more people to adopt the older youth.D.To tell the readers not to blindly believe others.第二节:七选五(共5小题:每小题2分，满分10分)阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。
