It’s a very interesting park, full of wild animals running freely.When we got there, we bought our tickets and drove into the park. We were very excited at the thought of going to see the lions. But to get to the lions’ place we had to go through the monkeys’ land first. And that was an unforgettable experience because they climbed all over the car, ate apples and bananas, and threw all kinds of things at us. They seemed very unfriendly.Anyway, we went on our way to the lions’ place where we had to lock ourselves in the car as we knew lions could be dangerous. A lion came up very close to us. Then it was on the bonnet (车盖). It looked calm but we felt terrified. Aunt Emily, who isn’t very brave, started to call for help. The kids started crying. Only my brother, George, stayed cool. I sounded the horn (喇叭) but nobody heard us.In the end a guard arrived in his car, and the lion just got off our car and started smelling the guard’s hand as if nothing was the matter.4．Which animal did the author want to see the most?A．The lions.B．The elephants.C．The monkeys.D．All of them. 5．Why did they lock themselves in the car?A．Because the monkeys might steal things.B．Because they were afraid of beingrobbed.C．Because the lions might be dangerous.D．Because something was wrong with the car.6．What does the underlined word “terrified” in Paragraph 4 probably mean?A．Excited.B．Bored.C．Interested D．Scared 7．Who stayed calm among the visitors when they met the lion?A．Aunt Emily.B．George.C．The guard.D．The author.I woke up this morning and it was harder to get out of bed than usual.I didn’t sleep well because I was very nervous. I had many questions. What should I wear? What should I put in my schoolbag?I finally fell asleep around5:45 and my alarm(闹钟) started going off at 6.Wellit was time for me to start my first day of high school.My first class wasn’t too bad. I had to listen to my English teacher discuss the importance of themes and plots(主题和情节)，but otherwise it was a pretty relaxing class. My other classes that followed were pretty much the same. Not too many cliques( 小团体)had formed yet from what I could see but then again, lunch hadn’t started yet. Thinking about all of this made me wonder where I would sit during lunchtime. I was hoping I wouldn’t feel too lonely and would find a good table to sit at and enjoy my lunch.I chose a pizza and an orange soda. I was thankful that the food didn’t taste terrible. More importantly,I managed to find some new friends to sit with so I wouldn’t have that on my mind for the rest of the day I was just happy I had a great lunchtime.My first day at school was almost over when I felt a tap( 轻拍)on my shoulder in Chemistry class. It was a girl named Samantha asking if she could read my textbook with me because she left hers at home.I told her yes and invited her to sit next to me. When the class bell rang, we exchanged numbers to hang out after school.I felt like my day couldn’t have gone any smoother.I just had one more class to get through and I would be done for the day. 8．What happened to the author before her first day of high school?A．She almost didn’t sleep the night before.B．She kept asking her parents questions.C．She didn’t find her schoolbag.D．She failed to get up early.9．What did the author worry about before lunch?A．Not finding her way to the dining room.B．Having lunch with her English teacher.C．Not having enough time for lunch.D．Being alone during lunchtime. 10．What did Samantha ask the author to do?A．Send her home.B．Sit together with her.C．Share a textbook with her.D．Guide her to a classroom.11．Why did the author write the text?A．To describe her first high school day B．To encourage students to study hard.C．To talk about her favorite course.D．To introduce her new friends.It’s time to go back to high school. Students are excited about the new beginning. But for many kids, the first day is more about friends than classes, and maybe with good reason. On that day, the teacher takes attendance (考勤), hands out books, and describes the teaching plan. If a student hears the same things in seven classes, you can’t blame (责备) them forthinking it’s going to be another long year. When the high schoolers’ parents ask what they did in school, it’s pretty likely that the answer will be “Nothing.”It doesn’t have to be this way. Kids always want exciting changes, and you can give them a taste of how interesting your course will be. One English teacher asks students to write 77 words about what they want to get out of her class. Then she reads their responses (回答) out aloud. She keeps the responses until the last day of the school year when she hands them back to students so they can see if they achieved what they wanted. After encouraging kids with a year-long game, she begins the English course.On the first day of science, a teacher gives students 30 minutes to build something to improve people’s lives. A history teacher organizes a debate on whether Swiss cheese is better than cheddar. In math class, another teacher puts students in groups of three, and gives them six minutes to come up with as many answers as possible to the question, “What is math good for?”The new class activities are part of our school wide movement to improve the first day of classes. Many teachers choose to use creative ways to encourage kids from day one. And all students seem to enjoy the changes. Quite a few parents told me that their kids said, “I think English (or math or biology or Spanish) is going to be great!”12．Which best describes the class on the first day of school in paragraph 1?A．A bit strange.B．Too boring.C．Really wonderful.D．Quite challenging.13．What will the students find out in English class at the end of the school year?A．If their expectations have been realized.B．If their writing skills have improved.C．If they can understand the 77 words.D．If the teacher likes their responses.14．What do the teachers in paragraph 3 have in common?A．All ask students to work in groups.B．All choose to do something exciting.C．All hold discussions on teaching plans.D．All try to improve students’ creativity.15．What is the author’s altitude to the movement?A．She shows little interest in it.B．She feels surprised at it.C．She is worried about it.D．She supports it.二、七选五You would want to make a good impression when you introduce yourself on the first day in class at your school wouldn’t you? In this post, it will cover what to include in your introduction.The startYou can start with the obvious (明显的) information — your name. 16 You can be a bit creative by starting with something different. You can start with an unusual experience or an interesting fact about your city or an unusual hobby.17The city you come from. You may add a sentence or two about the city as well if there is something interesting to talk about.Maybe the city is known for its historic monuments (历史遗迹). 18 And if you’ve lived in different cities, you may briefly (简洁地) mention their names and,as mentioned above, a sentence or two on the most interesting parts of them.What are your interests and hobbies?Playing a sport? Traveling? Reading? Kite flying? Or something unusual,such as toy collecting? 19 For example if you’ ‘re into reading, mention your favorite books, your favorite author, and how reading has influenced you.Where can you help others?If you have a strength (长处) others in your class can benefit (受益) from, feel free to share it.For example, if you’re good at dancing, you can teach anyone who’s interested. If people know your strengths, they’ll readily turn to you when they need help. 20 And if you think helping others may be a waste of time, you should remember that you too may need help in areas where others are stronger.A．Where are you from?B．But that’s a common start.C．Where did you last attend the school?D．Maybe it’ s famous for its natural beauty.E．This is an easy way to make friends in high school.F．Describe small facts if you’ve followed the hobby with serious interest.G．The organizer may ask to include your family and the place you come from in the introduction.三、完形填空A long time ago, there lived a girl named Lilly.When she started going to school, sheshe knew all the 23 .Out of all the subjects, her favorite subject was sports.

2011年真题及参考答案812

首先，抗日战争爆发以后，为了全面抗日，文坛渐渐停止三十年代那些无休止的激烈纷争，左联为左协代替。毛泽东在延安座谈会上的讲话给文坛指明了发展方向，产生了巨大影响，出现大量人民作家和人民文学。赵树理即是一大代表。周扬指出“赵树理同志的作品是文学创作上的一大收获，是毛泽东文艺思想在创作实践上的一个胜利。”
4、简述《浮士德》的悲剧历程；结合引文谈谈你对《浮士德》中“两个赌赛” 及其结果的理解。
答：《浮士德》德国伟大的文学家歌德的代表作。通过浮士德的悲剧一生来探讨人的命运以及不可打败的精神。
（一）浮士德的悲剧历程
（1）知识的悲Байду номын сангаас（2）爱情的悲剧（3）政治悲剧（4）美的悲剧（5）事业悲剧
现在看来，赵树理的出现和成功也很值得讨论。一方面有其积极的影响，另一方面，站在今天的角度，或者说文学自身发展的道路上来看，以赵树理为代表的那一代文学也产生了消极影响。文学与政治联系过于紧密，难免产生很多不属于文学的东西，思想性强而艺术性不足。排挤其他文学的生存，导致后来越演越烈而酿成大祸，最终也不利于文学的健康发展，这是我们应该警惕的。
1、答：词汇和词义的发展是和社会的发展、人们对现实的认识的变
化联系在一起的。新事物的出现，旧事物的消亡，认识的深化，都会在词汇和词义中打上自己的印记。
这种发展变化具体表现在三个方面：新词的产生、旧词的消亡，词语的替换，词义的演变。
（1）新词的产生与现实中出现新的事物有联系。例如，导弹，核弹等，是随着工业化进程产生的。构成新词的材料，有些是从外语借来的，例如瓦斯，柯达等。

It has been argued by some that gifted children should be grouped in special classes。

The 1 has been on the belief that in regular classes these children are held back in their intellectual (智力的) growth by 2 situation that has designed for the 3 children.There can be little doubt that 4 classes can help the gifted children to graduate earlier and take their place in life sooner. However, to take these 5 out of the regular classes may create serious problems.I observed a number of 6 children who were taken out of a special class and placed ina 7 class. In the special class, they showed little ability to use their own judgment, relying8 on their teachers’ directions. In the regular class, having no worry about keeping up, they began to reflect 9 on many problems, some of which were not on the school program.Many are concerned that gifted children become 10 and lose interest in learning. However this 11 is more often from parents and teachers than from students, and some of these 12 simply conclude that special classes should be set up for those who are 13 . Some top students do feel bored in class, but why they 14 so goes far beyond the work they have in school. Studies have shown that to be bored is to be anxious.

广东省湛江市雷州市第二中学2024-2025学年高一上学期10月月考英语试题

广东省湛江市雷州市第二中学2024-2025学年高一上学期10月月考英语试题一、阅读理解The following list focuses on the top 4 not-to-be-missed world-class parks, helping tourists better explore the city of Atlanta.Centennial Olympic ParkCreated for the 1996 Olympics, this park is well worth a visit. Visitors can be entertained by free music and lots of public art. Photography lovers should take advantage of all the photo opportunities the park affords. One of the big draws especially for children in summer is the fountains. Sometimes there are free concerts and movies in the park. Overnight campgrounds are offered.Chattahooche Nature CenterVisitors can begin their exploration at the Discovery Center, where they can see Atlanta from the top. There’s also a river boardwalk crossing the wetland area. Besides effortless and short-distance hiking paths, there is a variety of native wildlife as well. Don’t miss Wildlife Walk, where visitors can enjoy close and personal views of native animals and plants.Chastain Memorial Park and AmphitheatreApart from the running and walking roads, there’re also tennis courts and fields for playing ball games. Looking for a spot to host a family get-together? This could be an ideal place as there`re many pavilions(亭子)available. Kids can play on the special playgrounds. Of course, there is an amphitheater, which hosts outdoor concerts during summer.Cloudland Canyon(峡谷)State ParkFeaturing a beautiful canyon, this park is one of the largest and most scenic parks in Atlanta. At the bottom of the canyon are two waterfalls, where visitors can watch the water run over the sandstone. There are several different hiking paths around the park, but some may take several hours. If you’d like to stay overnight, there are regular camp places.1．What do Centennial Olympic Park and Cloudland Canyon State Park have in common?A．They offer campsites.B．They have beautiful fountains.C．They host photo exhibitions regularly.D．They are equipped with top tennis courts. 2．What can a tourist do in Chattahooche Nature Center?A．Interact with rare animals.B．Have a bird view of the city.C．Take challenging hiking routes.D．Row a boat across the wetland.3．Which is the best place for people to have a family party?A．Centennial Olympic Park.B．Chattahooche Nature Center.C．Chastain Memorial Park and Amphitheatre.D．Cloudland Canyon State Park.Natural disasters take many different forms and can happen without warning.The surface of the Earth has not always looked as it does today; it is moving continuously and has done so for billions of years. This is one cause of earthquakes, when one section of the Earth (tectonic plate) crashes with another. Scientists can predict where (but not when) this might happen and the area between p lates is called a fault line. However, earthquakes do not always happen on fault lines, which is why they are so dangerous and unpredictable.V olcanoes happen where the earth’s crust (地壳) is thin — lava (熔岩), dust and gases burst out from beneath the earth. They can rise into a massive cone (锥体) shape — like a mountain — and erupt, or they can be so violent that they just explode directly from the earth with no warning. However, scientists are becoming more skilled at predicting volcanic eruptions.Hurricanes are extremely strong storms and often happen in the Caribbean. They cause high winds, huge waves and heavy flooding and can be hundreds of miles across.Floods happen in many countries after very heavy rainfall. When rain pours for weeks at a time, rivers overflow and people and belongings can be trapped or simply washed away.Another kind of natural disaster is a drought. This happens when there is no water — when it doesn’t rain for a long time and rivers dry up. Plants, animals and even humans die as a result of drought, for we all need water to live.All the disasters mentioned above are very dangerous and continue to kill thousands of people each year, but they are nowhere near the most dangerous disaster to ever happen on earth: asteroid (小行星) impacts. About once every million years the Earth is hit by a piece of rock and ice from space large enough to cause massive destruction and sometimes to kill entire species. 4．What is Paragraph 2 mainly about?A．Why an earthquake happens.B．How scientists describe an earthquake.C．When sections of the Earth crash.D．What the surface of the Earth looks like. 5．Which of the following is the most dangerous natural disaster?A．V olcanoes.B．Hurricanes.C．Droughts.D．Asteroid impacts. 6．How many natural disasters are mentioned in the text?A．4.B．5.C．6.D．7.7．How does the author develop the text?A．By expressing opinions.B．By listing examples.C．By telling some stories.D．By describing experiences.I presented a group project to my classmates. The first question asked was, “What words do you associate with rural education?” Some of the responses were positive.Others accurately portrayed a few of the negatives like “isolated” and “underfunded.” But I was surprised that some used words like “hillbillies” and “hicks” (乡巴佬).Previously, I felt proud of myself as a student from rural West Virginia. But at that moment, my pride sank. For a place that claims to welcome all, the Brown University has actually left its rural students feeling looked down upon.For a while, I never mentioned where I called home unless it was absolutely necessary. By the third month of my first year, I was prepared to transfer out of Brown and finish college at a school where I would be surrounded by people like me, people from rural communities. Then I realized that this response was just the one that my tormentors expected.Now I have decided to fight back. We need to change. But this deeply-rooted culture won’t change on its own. The University and its non-rural students can’t and won’t do it. So it is up to us, the rural students, to make a difference. So rural students, talk with your long, drawn-out accent, defend your hometown of hard-working people and condemn (谴责) the ignorance that attempts to deny your personhood. We must uplift other rural students in their academic and professional careers. We must be the ones to support each other.What we need is a club for that exact purpose. A rural students’ collective is the formal meeting place that we need and deserve. In an institution where rural students feel lost and deserted, we will soon find a common ground for each other.For the non-rural students and faculty wondering how to support us, don’t stick to yourstereotypes (刻板印象) that rural students are dumb, ignorant and unintelligent. On the contrary, we are valuable, deserving and hard-working individuals. Brown’s faculty and students should welcome and embrace our contributions.8．How did the writer feel after presenting the group project?A．Frustrated.B．Proud.C．Angry.D．Confused. 9．What group of students does the underlined word “tormentors” in Paragraph 2 probably refer to?A．Those who come from rural West Virginia.B．Those who are determined to make a change.C．Those who used words like “hillbillies” and “hicks” in their remarks.D．Those who associated rural education with “isolated” and “underfunded” .10．How does the writer think rural students should fight back?A．They should turn to the college authority for help.B．They should unite and reach out to assist each other.C．They need to setup a special club for all the students.D．They are supposed to avoid speaking with their local accent.11．What message does the writer want to convey?A．Positive attitudes contribute to a harmonious college.B．Discrimination is a common phenomenon in Virginia.C．Rural students in Brown are valuable and deserve respect.D．The Brown University badly needs to adjust its moral education.A new study has found that smiling at London bus drivers increases happiness. The finding feels obvious and unexpected at the same time. The authors of the research, which was conducted by the University of Sussex and others, hope it will lead to “more interaction and kindness on buses”. On the Number 24 bus to Hampstead Heath, Londoners are sceptical. “Bus drivers,” says Liz Hands, a passenger, “are generally annoying.”It might seem improbable that a report on London’s buses could change behaviour. But it has happened before. London’s buses have an underappreciated role in the history of medical science. In the 1940s, a single study of London’s transport workers transformed epidemiology (流行病学), medicine and the way we live now. Every time you go on a run, check your step-count, or take the stairs instead of the lift, you are following a path pioneered by the feet of the workers on London’s buses.In the late 1940s, doctors were worried. Britain, like many rich countries, was suffering from an “epidemic” of heart disease and no one knew why Various hypotheses (假设), such as stress, were suggested; but one thing that was not exercising researchers was exercise. The idea that health and exercise were linked “wasn’t the accepted fact that we know today”, says Nick Wareham, a professor of epidemiology at Cambridge University. Some even felt that “too much physical activity was a bad thing for your health”. Miners and farmers who did physical exercise also suffered from various diseases and died young.At this time a young doctor called Jerry Morris started to suspect that the increasing deaths from heart disease might be linked to occupation. He began studying the medical records of 31,000 London transport workers. His findings were breathtaking: conductors, who spent their time running up and down stairs, had an approximately 30% lower possibility of disease than drivers, who sat down all day. Exercise was keeping people alive.Morris’s research was eventually published in 1953, just three years after a study by Richard Doll proving the link between smoking and lung cancer. Morris’s work had consequences both big and small. Morris now also took up exercise, handing his jacket to his daughter and just running. “People thought I was bananas.” Slowly, the rest of the world took off its jacket and followed.12．What can we learn from the first two paragraphs?A．The former study made much difference.B．Running was regarded as harmful behavior.C．Smiling at drivers can cure passengers’ diseases.D．London passengers can understand bus drivers well.13．What does the underlined part “exercising researchers” in Paragraph 3 probably mean?A．Encouraging researchers to work out.B．Helping with researchers’ inquiry.C．Holding back researchers’ progress.D．Drawing researchers’ attention.14．How did Morris conduct his study on the transport employees?A．By carrying out survey.B．By observing their routines.C．By doing medical examinations.D．By analyzing the medical data.15．What is the best title for the text?A．Smiling and Its Effects on London Bus Drivers.B．The Evolution of London’s Transportation System.C．How London Bus Drivers Led the world to exercise.D．What Londoners Think about Studies on Bus Drivers.We all have times in our lives when we just have too many things to deal with. 16 Well, that’s crazy, because if you get ill then you’re going to be able to do nothing. Here are some ideas to take care of yourself.17 Living with clutter (杂乱) and never being able to find what you need when you need it causes stress. Take time to develop a system and then use it. Instead of keeping all the things you need to do in your head, write them down on a piece of paper.Spend 30 minutes per day on personal development. 18 And negative ones will disappear. If we want to be successful in work and life, we need to develop the habit of feeding our minds in a positive way. So take in good inspiring information.Say no to anything that is not important to you. Give yourself permission to focus on what’s important. Getting the unnecessary, tiresome responsibilities off your schedule will give you more time and space. 19 Take 5minute minibreaks every hour. 20 So no matter how efficiently you work, you should always have your mind relaxed or end up spending time doing other things when you try to keep going hour after hour. Instead, break up each hour by getting up from your chair and walking outside to take a 5minute break.A．Get organized.B．Write a journal entry every day.C．You can’t stay focused all the time.D．Fill your minds with positive thoughts.E．Besides, it will reduce the pressure that you feel.F．As a result, we often forget to look after ourselves.G．Eating healthily is one of the most sensible things you can do for yourself.二、完形填空When light snow began falling, the principal kept a careful eye on the approaching storm.

广东省湛江市普通高中上学期高二语文2月月考试题含答案

上学期高二语文12月月考试题11第Ⅰ卷一、阅读下面的文字，完成1～3题。

（9分，每小题3分）“微小说”，文学下一站?首部“微博小说"《围脖时期的爱情》正式出版后，关于“微小说”的讨论进一步被提上台面。

褒扬者盛赞其“以小搏大”，以区区百余字试图和动辄上万言的传统小说分庭抗礼;同时,批评者表示悲观，认为“微小说”不过是网络上诸多新鲜尝试的一种，在潮流过后必将走向衰落。

“微小说”以“微博”这一新兴社交网站为载体，起初只是微博用户的独立创作，处于基本无声的状态。

直到2010年年末，坐拥微博市场半壁江山的新浪举办了“微小说大赛”，获得了公众的广泛参与。

“微小说"因为这项赛事一度被推向了话题中心。

以《围脖时期的爱情》为例,可以看出“微小说"有如下几个特点:一、情节跌宕起伏。

大部分的创作者都采取了“抖包袱"的手段，以新奇取胜，在最后一刻达到了故事的反转。

二、读者对创作过程进行了高度参与.《围脖时期的爱情》这一连载的“微小说”在这一点上更为突出：除了男女主角的爱情主线，其他分支内容大部分由读者提供，根据他们的真人真事进行改编。

三、反映当下事件的时效性. “微小说”处于具体的时间序列之中，无论是政治时事、经济民生，还是网络评论、娱乐八卦,都可以如“吸星大法”般迅速地吸纳,或者化为情节元素，或者进行二次传播，或者褒贬调侃.“微小说”的流行究竟出自何种原因？有诸多网友表示，在网络时代，“微小说”应该也被纳入参量之中，这一民间的呼声与王国维先生早年所说的“一代有一代之文学”有不谋而合之感. 对于“微小说”的价值判断和前景预测，归根结底还不能脱离当下：“微小说"实际上是应“碎片化”的时代特征而生,紧张繁忙的快节奏生活让人不堪重负，清茶一杯、手不释卷的悠然已经是现代社会不可多得的奢侈。

我们行走于都市喧嚣之中,连贯阅读的可能性被消解，于是,“微小说"、“短信小说"、“手机报”等新形式应时而生。

解析若将凸透镜对准窗外景物,此时物距远大于2f,在外壳内前后移动内纸筒,
在半透明膜上可以得到景物倒立、缩小的实像。根据题意知道,外壳的长度为1 6 cm,所以成实像时最大像距为16 cm,且满足16 cm>2f,由此可知f<8 cm。在同一位置观察同一个物体时,若将凸透镜换为带小孔的不透明纸板,则会发生小孔成像,物体在半透明膜上成实像,形状不变。
于10 cm的是丙 (选填“乙”或“丙”);凸透镜越厚,其焦距越短
(选填“长”或“短”)。
解析乙图中光线在距离水透镜更近的地方会聚,焦距小于10 cm,丙图中光线
在距离水透镜更远处会聚,焦距大于10 cm。根据甲、乙、丙三图可以发现,凸透镜越厚,其聚光能力越强,焦距越短。
