成都七中高2025届高二语文10月阶段性考试试卷及参考答案

成都七中2023～2024学年度上期高2025届10月阶段性测试语文试题考试时间：150分钟总分：150分一、现代文阅读（本题共4小题，18分）阅读下面的文字，完成1～4题。

非攻鲁迅墨子走进宋国的国界的时候，草鞋带已经断了三四回，觉得脚底上很发热，停下来一看，鞋底也磨成了大窟窿，脚上有些地方起茧，有些地方起泡了。

他毫不在意，仍然走;沿路看看情形，人口倒很不少，然而历来的水灾和兵灾的痕迹，却到处存留。

走了三天，看不见一所大屋，看不见一棵大树，看不见一个活泼的人，看不见一片肥沃的田地，就这样的到了都城。

城墙也很破旧，但有几处添了新石头;护城沟边看见烂泥堆，像是有人淘掘过，但只见有几个闲人坐在沟沿上似乎钓着鱼。

“他们大约也听到消息了。

”墨子想。

他决计穿城而过，于是走近北关，顺着中央的一条街，一径向南走。

城里面也很萧条，但也很平静;店铺都贴着减价的条子，然而并不见买主，可是店里也并无怎样的货色;街道上满积着又细又粘的黄尘。

“这模样了，还要来攻它!”墨子想。

他在大街上前行，除看见了贫弱以外，也没有什么异样。

楚国要来进攻的消息，是也许已经听到了的，然而大家被攻得习惯了，自认是活该受攻的了，竟并不觉得特别，况且谁都只剩了一条性命，无衣无食，所以也没有什么人想搬家。

待到望见南关的城楼了，这才看见街角上聚着十多个人，好像在听一个人讲故事。

当墨子走得临近时，只见那人的手在空中一挥，大叫道：“我们给他们看看宋国的民气!我们都去死!”墨子知道，这是自己的学生曹公子的声音。

然而他并不挤进去招呼他，匆匆的出了南关，只赶自己的路。

又走了一天和大半夜，歇下来，在一个农家的檐下睡到黎明，起来仍复走。

草鞋已经碎成一片一片，穿不住了，包袱里还有窝窝头，不能用，便只好撕下一块布裳来，包了脚。

不过布片薄，不平的村路梗着他的脚底，走起来就更艰难。

到得下午，他坐在一株小小的槐树下，打开包裹来吃午餐，也算是歇歇脚。

远远的望见一个大汉，推着很重的小车，向这边走过来了。

A,B,C,and D.You should decide on the best choice and mark the corresponding letter on the Answer Sheet.Passage OneDoctors have known for a long time that extremely loud noises can cause hearing damage or loss.The noise can be the sound of a jet airplane or machines in factories or loud music or other common sounds found at home or at work.A person only needs to hear the noise for a little more than one second to be affected.An American scientist has found that using aspirin can increase the temporary hearing loss or damage from loud noise.He did an experiment, using a number of male students at a university who all had normal hearing.He gave them different amounts of aspirin for different periods of time,and then he tested their hearing ability, He found that the students who were given four grams of aspirin a day for two days suffered much greater temporary hearing loss than those who did not use aspirin.The hearing loss was about two times as great.The scientist said millions of people in the United States use much larger amounts of aspirin than were used in the study.He said these people face a serious danger of suffering hearing loss from loud noise.61.Hearing damage loss may be caused by_____________.A.loud musicB.the sound of a jet airplane or machinesmon sounds at home or at workD.all of the above62.The passage suggests that one's hearing_________________.A.will be damaged

exciting to apply for a job that really appeals to you.In making your application,there are a number of points for you to observe.In your letter of application,say just enough to give a good account of yourself without being wordy.If you are answering an advertisement,any information for which it asks must,of course,be given.This will usually cover your academic record and any further education and training.You may also be asked to give the names of one or two persons to supply references. For this purpose you should choose people who know you well enough to vouch(保证)for your character and ability;and to be polite,you should seek in advance their permission to be named as referees.It will depend on circumstances how much you can carefully add about yourself.Your purpose is to bring to the notice of the employer any good reason why you rather than any of the other applicants should be chosen for the job.Therefore,if you feel you have any special skill or talent for the work,or particular interest in the line of the business,let it be known.Finally,there is your use of language,You cannot go wrong if you keep your sentences and paragraphs short,making sure the sense is clear and well-expressed.Choose plain words so long as they convey the meaning.66.The aim of

host will provide accommodation and meals.Rooms will be cleaned and bedcovers will be changed at least once a week.You will be given the house key and the host is there to offer help and advice as well as to take an interest in your physical and mental health.Homestays are located in London,mainly Zone2.Most hosts do not live in the town centre as much of central London is commercial and not residential.Zones3and4often offer larger accommodation in a less crowded area.It is very convenient to travel in London by undergroundMeal Plans Available◊Continental Breakfast◊Breakfast and Dinner◊Breakfast,Packed Lunch and DinnerIt's important to note that few English families still provide a traditional cooked breakfast.Your accommodation includes Continental Breakfast which normally consists of fruit juice, cereal,bread and tea or coffee.Cheese,fruit and cold meat are not normally part of a Continental Breakfast in England.Dinners usually consist of meat or fish with vegetables followed by dessert,Fruit and coffee.FriendsIf you wish to invite a friend over to visit,you must first ask your hosts permission.You have no right to entertain friends in a family home as some families feel it is an invasion of their privacy.Self-Catering Accommodation in Private HomesAccommodation on a room-only basis includes the shared kitchen and bathroom facilities and often a main living room.This kind of accommodation offers an independent lifestyle and is more suitable for the long-stay student.However,it does not provide the same family atmosphere as an ordinary homestay and

more freedomPassage FourThe native Americans,the people we call the"Indians",had been in America for many thousands of years before Columbus arrived in1492.Columbus thought he had arrived in India. so he called the native people"Indians”.The Indians were kind to the early settlers,They were not afraid of them and they wanted to help them.They showed the settlers the new world around them.They taught them about the local crops like sweet potatoes,corn and peanuts.They introduced the Europeans to chocolate and to the turkey;and the Europeans did business with the Indians.But soon the settlers wanted bigger farms and more land for themselves and their families.More and more immigrants were coming from Europe and all these people needed land. So the Europeans started to take the land from the Indians.Naturally,when the whites started taking all the Indian’s land,the Indians started fighting back.But the whites were stronger and cleverer.Slowly they pushed the Indians into those parts of the continent that the whites didn't want-the parts where it was too cold or too dry or too mountainous to live comfortably.By1875 the Indians were living in special places called"reservations".But even here the whites took landfrom them-perhaps the whites wanted the wood,or perhaps the land had important minerals in it, or they even wanted to make national parks there,So even on their reservations the Indians were not safe from the whites.There are many Hollywood films about the fight between the Indians and the whites. Usually in these films the Indians are bad and the whites are good and brave,But was it really like that?What do you think?Do you think the Indians were right or wrong to fight against the whites?76.Why did Columbus call the native people"Indians"?A.Because he thought he had arrived in IndiaB.Because he knew they were from IndiaC.Because he liked Indian culture very muchD.Because he was an Indian himself77.How did the Indians react to the early settlers'arrival at first?A.They were angry at the early settlersB.They seldom helped the early settlersC.They fought against the early settlers fiercelyD.They were warm-hearted and kind to the early settlers78.Which of the following statements is TRUE according to the passage?A.The settlers wanted to buy land from the IndiansB.The Indians were stronger and cleverer than the settlersC.The whites even wanted more land on Indians’reservationsD.The Indians gave up their land willingly79.We can learn from the last paragraph that________________.A.films about the fight between the Indians and the whites are very limitedB.the Indians are usually beautified in the filmsC.the author is doubtful about what the films show to usD.films about fights are the most popular ones in the market80.The passage is most probably taken from the_______________column of a newspaper.A.entertainmentB.historyC.economyD.culture PartⅣTranslation(2×10)Directions:There are10sentences in this part,Please translate sentences81-85from Chinese into English,and translate sentences86-90from English into Chinese.Write your answer on the Answer Sheet.81.我们现在住的房子离公司太远了。

2023-2024学年度高二年级阶段性考试语文试题含答案解析

2023-2024学年度高二年级阶段性考试语文试题一、现代文阅读（35分）（一）现代文阅读Ⅰ（19分）1. 阅读下面的文字，完成下面小题。

材料一：“义”与“利”的关系，是中国思想史上争辩不休的一个大问题。

先秦儒家认为“义”和“利”是对立的。

孔子说：“君子喻于义，小人喻于利。

”孟子说：“何必言利，亦有仁义而已矣。

”他们认为，对利的追求是造成社会混乱、国家动荡的根源。

实际上，儒家也并不是根本不言利，只是要把义放在首位，反对后义而先利罢了。

在这个问题上，墨家和儒家有所不同。

由于墨子把“利”作为实践“兼爱”的行为准则，因此，在墨子那里，“利”也就是“义”，“重利”也就是“贵义”，二者是统一的。

这里有一个对于“利”的不同理解的问题。

孔子和孟子所谓的“利”，指的是专“利吾国”“利吾家”“利吾身”的狭隘“私利”。

虽然他们也提出什么“天下为公”，但这个“天下”只是封建君主的“家天下。

”。

墨子所谓的“利”，则是“爱利万民”“天下之利”的“公利”。

维护这样的公利，正是仁义的要求、道德的标准。

很明显，在墨家那里，“天下之利”“人民之大利”，是最高的伦理准则。

墨子认为“义”就是“利”，“利”就是“义”，主张贵义重利，追求义利合一。

墨子认识到，人类首先必须求得生存，为了生存，就不能不追求物质利益。

所以，避苦求乐、趋利避害是人的天性，“利，所得而喜也”，“害，所得而恶也”。

利和害、苦和乐都是相对的，人们通过比较权衡，利中取大，害中取小，趋利避害，此种行为上至王公贵族，下至平民百姓，莫不如此。

墨子从人性的角度，论证了人们追求物质利益的合理性，对人们的求利动机给予了有力的辩护。

墨子认为公利，即社会的整体利益是至上的，个人只能作为群体的部件而行动，任何人只有维护并实现了整体利益，个人利益才能得到显现。

在他利与自利之间，应该从他利出发再到自利。

虽然墨子重视天下之利，把“亏人”“自利”视为人们互不相爱的思想根源，但是墨子并不是笼统地反对“自利”，墨子反对的是“亏人”而“自利”、损人而利己的行为。

以下是一个ACCA考试科目的样题：题目：A公司是一家制造企业，生产多种产品。

为了计算盈亏平衡点，需要哪些数据？请列举所需数据并解释其用途。

答案：为了计算盈亏平衡点，需要以下数据：1. 固定成本数据：固定成本是指在一定时期内不随产量变化而变化的成本。

这些成本通常包括租金、工资、保险费等。

固定成本数据将用于计算盈亏平衡点时的总成本。

2. 变动成本数据：变动成本是指随着产量变化而变化的成本。

这些成本通常包括直接材料、直接人工和与产量直接相关的费用。

变动成本数据将用于计算每单位产品的成本。

3. 销售价格数据：销售价格是指每单位产品的售价。

销售价格数据将用于计算销售收入。

4. 预计销售量数据：预计销售量是指企业在一定时期内预测的产品销售数量。

预计销售量数据将用于计算销售收入和总成本。

通过以上数据，我们可以计算盈亏平衡点。

盈亏平衡点是指企业在一定时期内所获得的总收益与总成本相等时的状态。

计算盈亏平衡点可以帮助企业了解在什么情况下能够盈利或亏损，从而制定相应的经营策略。

He liked his new school and made friends there, but then things at home started to change. His mum and dad began to argue and the arguments got worse and worse until one day, Daniel's mum left. With his father working long hours, Daniel felt very lonely and very unhappy. He wanted to escape, to run away. And that's what he did.Very early one terribly cold morning when the snow was deep on the ground, he packed a bag with some clothes, some chocolate and a map of Canada and set off to a forest. He ran and ran until he could hardly breathe. His feet were heavy with the snow but he still walked on through deep snow, not even watching where he was going.Then, disaster struck. A rock hidden by the deep snow caught his feet and Daniel fell to the ground. He had broken the bone. He was very cold and was starting to feel tired, but he knew that if he fell asleep in the snow, he would certainly die from the cold.A tree shook ahead. From within the branches(树枝), a pair of yellow eyes watched Daniel. The puma had been following him. A puma is a large wild cat with claws that could tear（撕开）Daniel into pieces. But instead of moving in for the kill, the puma walked up to Daniel and lay across his chest, arms and legs. Daniel was too frightened to move, but soon the warmth of the animal reached Daniel and he began to feel better. From time to time, the puma pressed his muzzle (口鼻) against Daniel and rocked his head gently. Clearly, the puma knew that Daniel must not fall asleep. This animal should have been a real danger to Daniel and yet the boy began to feel safe.They remained like that for several hours until Daniel and the puma heard voices. The rescue (援救) team had found them.1. Daniel ran away from home because ______.A．he had a big argument with his fatherB．he wanted to learn to be independentC．he didn’t get enough care from his parentsD．his parents were always arguing at home2.

Why did the puma press its muzzle against Dan and rock his head gently from time to time? A．To keep Daniel warm. B．To play with Daniel.C．To kill Daniel. D．To keep Daniel awake.5. What is the best title for the story?A．Puma in danger B．A caring pumaC．Rescue of a boy D．A homeless boyB.Choose the words or expression and complete the passage.The difference between happy people and unhappy people is their level of gratitude(感激).

They are the bosses of the Asian jungles with their cleverness, quickness and strength. A pussycat, on the other hand, is a homebody that comforts us with its gentle warmth and calms us with its purring.As a mother, the Chinese-American writer Amy Chua is definitely a tiger. Her book, Battle Hymn of the Tiger Mother (虎妈战歌) tells of the strict upbringing she gave her two children. She thinks that being strict is the only way to d__1__ a child's potential and to make them strong, i__2__ and successful. Her kids were not allowed to watch TV or play video games. They were not allowed to "hang out" with other kids after school. They had to be the top students in their classes. And they had to p__3__ the piano and violin for hours every day. As a result, her kids became successful. She admits this caused a lot of tears and anger but she has few regrets (后悔).Chua says, like her, most A__4__ mothers are tigers because they believe their children can a__5__ a lot if they're pushed hard enough. She says American mothers are really cats. They care more about their children's self-esteem (自尊). They don't want to push their kids too hard for fear of hurting their feelings. W__6__ soft words and understanding, they encourage their children to find their own path.So, is a tiger mom better than a pussycat? Perhaps it depends on the differences between Asian and Western cultures. It may also depend on the child himself. Some kids need to be pushed w__7__ others respond to a gentler hand.To growl or to purr? There is no easy answer.D.Answer the questions.stars". But they are not really stars. They are man-made satellites. And the biggest of all is the International Space Station (ISS). From May to July is the best season to watch the ISS flying over the earth. And people can see it with their eyes during the time.The scientists want to live on the ISS. They think that the best way to learn more about space is to live there.When the space station is finished, it will be like a city in space. People will stay and study there with many of the thing they have at home. Laboratories, living rooms and power stations are being built. The ISS is the most ambitious(雄心勃勃的) and expensive program. Billions of dollars are spent on it every year.Scientists hope that the ISS will be a stepping stone（跳板）for future space exploration. "The ISS will be more useful some day. The ISS will help us understand the human body better, explore space and study the earth. It can help us make life on the earth better." said Kathryn Clark, an ISS scientist.Sixteen countries are part of the space program: the US, Russia, Canada, Japan, Brazil, and 11 European countries.China isn't an ISS country, but it has helped with some of the experiments. In 2003, China sent some rice up to the ISS to find out what space would do to it.After it’s finished, more than 90 percent of the world’s population is able to see the Space Station. So keep looking up, and maybe you’ll see it getting bigger.1.What does ISS represent? _________________________2.How fast does ISS fly? __________________________________3.Give 2 examples of the items that are being built on the ISS. ___________,___________4.China is not an ISS country, is it? _____, _____.5.Why do scientists build ISS? _____________________6.What advantage do you take over the project of ISS?position: write a letter to your friend Anna.Anna is sad, because her mother doesn’t allow her to use the computer or surf the Internet.Try to give her some advice.
