2023-2024学年北京汇文中学九年级上学期期中考试语文试卷含详解
2023-2024学年北京汇文中学初三上学期期中语文一、基础•运用（每题2分，共14分）某校初三年级组织学生开展“故宫文创发展之路”的文化探究活动，以下是同学们共同拟写的研究报告。
一、困境与出路①故宫博物院收藏的藏品高达180多万件，但以往留给参观者的印象却有些尴尬。
“你说你有宏伟的馆舍，但是大部分区域你都不开放；你说你有丰厚的文物藏品，但是绝大部分沉睡在库房里；你说你有世界上最大规模的观众，但是他们都是目不斜视地从前门走到后门，你就不是真正融入世界的博物馆【甲】故宫博物院第六任院长单霁翔曾这样痛心地说过。
②2013年8月，【乙】紫禁城杯【乙】故宫文化产品创意设计大赛首次向社会征集作品，明确了“把故宫文化带回家”的主题，奠定了故宫文创的基调：将民族文化借助创意产品融入现代生活。
此后，Q版的故宫娃娃、创意与实用兼具的朝珠耳机、“必购清单”故宫日lì、“朕就是这样汉子”折扇等系列产品相继面世，大批年轻粉丝直呼“故宫这波操作有点厉害”“和印象中不一样了”！故宫开始凭借实用性、趣味性并存的文创产品逐渐摆脱了以往曲高和寡的“阳春白雪．．．．”形象，huàn发出了勃勃生机。
1.同学们对划线词语的读音、写法有疑惑，请你帮他们指出判断有误的一项（）A.“馆舍”一词泛指房屋，应读作“guǎn shè”。
B.“日lì”的“lì”是“记录年月日和节气的书、表等”的意思，该词应写作“日历”。
C.“曲高和寡”一词原来指乐曲的格调越高，能跟着唱的人就越少，“曲”应读作“qǔ”。
D.“huàn发”一词指光彩外现的样子，应写为“涣发”。
2.同学们拿不准填入【甲】【乙】两处的标点符号，你认为最恰当的一项是（）A.【甲】。
”【乙】“”B.【甲】”。
【乙】“”C.【甲】。
”【乙】《》D.【甲】”。
【乙】《》3.“阳春白雪”一词原指战国时期楚国的一种较高级的歌曲，后泛指高深的不通俗的文学艺术。

2023-2024学年九年级上学期期中考试语文试题
班级姓名学号成绩金秋十月，北师大实验中学开展了“探寻中国大学足迹”的综合实践活动。
同学们从“走进清华园”“走近北大红楼”“线上参观西南联大博物馆”三个方面进行资料搜集和考察。
下面几段文字是他们撰写的探究报告，请你阅读并完成下列任务。
1. 请用正楷字书写“探寻中国大学足迹”八个字作为手册的标题。
（1 分）下面是同学们找的一则介绍清华园的材料，请阅读文字，完成第2-4 题。
人们经常把清华校园称为“清华园”，其实严格来说，“清华园”是专指以工字厅为主体的一组清代园林①这组园林始建于十八世纪初的清代康熙年间，建成于乾隆年间，可谓历史悠久。
清华园曾经是康熙时期皇族的京郊别墅——熙春园的一部分。
道光年间，熙春园分为东、西两园——东部的熙春园及西部的近春园。
近春园四面荷塘围绕，后因朱自清先生的一篇《荷塘月色》，招（zhì) 莘莘学子的青睐②东部的熙春园，即今之【举世瞩目】的清华园的前身。
据考证，康熙时期编辑的大型类书《古今图书集成》就是在东部的熙春园编辑、印刷的。
咸丰即位后，又将东园更名为“清华园”并亲题匾额。
现在我们所说的清华园，是指清华大学所在的本部校园，包括了最早的熙春园的全部，常被用来代指清华大学。
2023-2024 学年第一学期期中考试初三语文第1 页（共 12 页）清华园的秋景，千般旖旎，万种风情，令人【趋之若鹜】。
一位诗人曾有 过这样的描述：“清华园的秋，炽．烈又缠绵……秋风所至，翻覆纤手，摇落满树金辉。
”名园美景如斯，但更令人【拍手称快】的是其蕴含的“ 自强不息、 厚德载物 ”的清华精神。
这种精神传承百年，在清华结出了累累．．硕果，培养了 一批又一批在国人眼中【炙手可热】的学术大师、经世之才。
这种精神还将（rú) 养一代又一代人，为中华民族的复兴贡献更大的智慧与力量。
2．文段中加点字的读音和根据拼音所写的汉字，判断有误．．的一项是（2 分）A.“招 zhì ”此处的意思是“指招来；引起 ”，应写成“招致 ”。

He wrote a seven-page（页）paper. He wanted to have a horse farm one day. He even drew a picture of a horse farm in the paper.The next day he handed it in to his teacher.

But designer Belyaev doesn't think that forgetting to check the weatherforecastbefore going out should cause you to get wet. That's why he created Lampbrella, a lamp post（柱）with its own rain－sensing（感应）umbrella.The designer says he came up with the idea after watching people get wet on streets in Russia. “Once, I was driving on a cent ral Saint Petersburg street and saw the street lamps lighting up people trying to hide from the rain. I thought it would be fit to have a canopy(伞篷) built into a street lamp，” he said.The Lampbrella is a post－looking street lamp fitted with an umbrella canopy. It has a built－in electric machine which can open or close the umbrella. Sensors(传感器) then make sure that the umbrella offers walkers shelter（遮蔽）whenever it starts raining.Besides the rain sensor, there's also a 360° moving sensor on the street lamp which finds whether anyone is using the Lampbrella. After three minutes of not being used the canopy is closed.According to the designer, the Lampbrella would move at a rather low speed, in order not to hurt the walkers. Besides, it would be fixed on the ground to protect from possible lightning strike. Each Lampbrella would offer enough shelter for several people. Being fixed at 2 meters off the ground, it would only be a danger for the tallest of walkers.While there are no plans to take the Lampbrella into production, Belyaev says he recently introduced his creation to one Moscow Department, and believes that his creation could be fixed on any street where a lot of people walk but there are no canopies to provide shelter.1．. What does the underlined word “forecast” mean in Chinese?A．预报B．情况C．查询2．. For what purpose did Belyaev create the Lampbrella?A．To remind people to take an umbrella.B．To check the weather forecast.C．To protect people from the rain.3．Which of the following shows how the Lampbrella works?machine sensorsA．B．C．4．. Which of the following is NOT true according to the passage?A．His creation was inspired by an experience from Belyaev's words in Paragraph 2.B．Paragraph 5 mainly tell us about the Lampbrella’s safety.C．The Lampbrella will be put into immediate production.5．The best title for this passage should be _____.A．THE USE OF THE LAMPBRELLAB．HOW TO PREVENT RAINC．THE NEW INVENTION－LAMPBRELLAE17、In the past, going to a piano teacher was the only way to learn how to play the piano. You could have one lesson a week. If you didn’t have private(个人的) lessons, you could still learn piano, but you would have to learn it by yourself. This was easy for some, but very difficult for most. However, with technology as it is today, there is at last another way that you can take piano lessons. You can take an online course.An online course can save you lots of money. If a private lesson costs 30 or 40 dollars per week, just think about how quickly that adds up. You can take a complete online course in piano by spending a small part of the money that you would pay for taking weeks of private lessons. Also, private lessons are only usually one hour per week. If you have questions during the rest of the week, or if you forget something that your teacher said, you will have to wait for your next lesson to continue your learning. However, online piano courses are quite different.With an online piano course, you can work at your own pace(进度). You can also take as many lessons per week as you’d want, or go back and listen to your last lesson if you have forgotten anything. Most adults who want to learn how to play the piano enjoy being able to go back and listen to lessons they watched before. It can give you a good idea of what you were doing right, what you were doing wrong, and what you should be doing before the next lesson.Of course, if you need someone to sit beside you and give you instant feedback(及时反馈) while you are playing, you are not suggested to choose an online course. But most adult learners think they can get their own type of feedback by watching the course again and again.1．is not mentioned in the passage to learn to play the piano.A．Going to a piano teacher B．Asking experts for information C．Teaching oneself2．Going to a piano teacher is much more than having an online piano course.A．expensive B．convenient C．interesting3．If you choose an online piano course, you can .A．ask questions whenever you wantB．watch the lessons whenever you’d likeC．get some advice while you are playing the piano.4．Most adults like to go back and listen to the lessons again because .A．they needn’t spend any extra moneyB．they can ask some questionsC．they can know what they were doing right, what they were doing wrong5．How many advantages of an online piano course have been introduced in the passage?A．2 B．3 C．4F18、Captain(船长) Nemo invited me and my friends to go hunting with him in the forests of Crespo Island. I asked him why he was so interested in Crespo Island, “I thought you preferred the sea to being on land.”“I do,” replied the captain. “But these forests are under the sea.”After going through a door, we were about ten metres under the water. The light from the sun reached us. Everything looked very colourful. We were going deeper and deeper. At 100 metres deep, we could see quite well, and Captain Nemo stopped and pointed to some dark shapes. This was the forest. The “trees” in the forest were giant seaweed(海草), and all their “branches” were vertical(垂直的).We could not stop looking at them. Fish swam around the branches like birds in a forest.Suddenly, I saw a large sea spider about a metre tall. It was going to attack me. Captain Nemo's man killed it with his gun, but it reminded me that the sea could be as dangerous as it was beautiful. When we reached 150 metres, it was dark. The sun's light could not reach this depth(深度). We turned on our lights. We could see about 20 metres around us. Finally, we found Crespo Island—where a steep rock wall rose in front of us.We could go no further, so we walked back towards the Nautilus. Suddenly, Captain Nemo stopped and shot an animal with his gun, it was a beautiful and rare sea otter(水獭). At last, we could see the Nautilus. Several large sharks swam over us. Luckily they didn't see us. We re-entered the Nautilus safely. I was tired but amazed by what I had seen.1．What do “dark shapes” in Paragraph 3 refer to(指的是)?A．Trees. B．Seaweed. C．Rocks. D．Fish.2．According to the passage, which is the correct order?①Captain Nemo's man killed a sea spider.②The men returned to the Nautilus.③The men went to the forest.④Captain Nemo invited us to go hunting.⑤Captain Nemo shot an otter.A．④①③⑤③B．③④②⑤①C．④③①⑤②D．③④①⑤②3．What is the best title of the story?A．A Visit to a Sea Forest B．Death Under the SeaC．Captain Nemo and the Nautilus D．Attacked by Giant SpideⅤ.书面表达19、在日常生活中，我们经常看到许多文明的行为，让人发自内心地为之点赞，但有时也会看到一些不文明的行为和一些不良现象。
