They grew up, moved away, and became successful. They remained friends and shared an aim. The aim was to help boys aged 9 to 13 in their old neighborhood. They wanted to act as role models for young boys and to stop them from getting into trouble as they got older.They called their program The Elephant Men after reading how elephant families in Africa surround and protect their young when they are in danger. Reginald and Robert’s program supports the young men in inner cities who are at risk of losing their lives to drugs. Their idea is “protecting our youth with the power and belief of the elephant”.They look for different ways for young men to build respect for themselves and others. One way is to use sports, especially basketball, to bring them together. Another successful program is a four-week summer work program that includes more than 100 young boys. The boys pick up rubbish across the city in exchange for a $200 gift card with which they can buy school clothes. To be part of the program, the boys have to get a reference (介绍信) from an adult at their school who is willing to write something good about them. This gives the boys a reason to do well in school.“We know our program works,” says Reginald. “We have some kids in college now and the best day of the year for us is the weekend before school starts, when we see our boys in the stores buying their clothes and books for school.”4.What did Reginald and Robert hope to do?A.Be good examples for boys.B.Leave their hometown.C.Run their own business.D.Become well-known.5.Why is the program called The Elephant Men?A.It is the name of a book.B.It is based on a true story.C.It aims to protect the elephant.D.It has the same spirit as the elephant. 6.What do the boys need to do to be part of the summer work program?A.Buy clothes.B.Raise $200 for school to buy gifts.C.Collect rubbish.D.Get a recommendation from the school. 7.How does Reginald feel about The Elephant Men program?A.Grateful.B.Satisfied.C.Puzzled.D.Worried.The human brain remembers negative experiences more easily than positive ones. Our brains have developed in this way because threats, like dangerous animals, have a more immediate effect on people’s survival compared to positive things like food or shelter. As a result, you clearly know what makes you unhappy, but do you know what makes you happy?Research suggests that our level of happiness is partly shaped by the choices we make. If you’ve been chasing wealth, fame, power and some material things, you may be looking for happiness in the wrong places. Psychologists suggest that the following habits can make people happier.People who own close relationships tend to be happier than those who do not. The number of our friends is not important. What matters is the quality of our relationships. Relationships that bring happiness usually consist of the sharing of feelings, acceptance, mutual (双方的) respect and trust.People who exercise regularly can improve both their physical and mental well-being. Some research has shown that exercise can be as effective as some medicine in treating depression.If we are so interested in an activity, we may lose track of time, and we can be in a state of flow. The activity could be playing the piano, surfing the Internet or playing a game… People who experience flow in their work or life tend to be happier.People are more likely to be happy if they know what their strengths are and can use them regularly. People are especially happy when they can set goals and use their strengths toachieve them.People, who think positively by being grateful, mindful and optimistic, are more likely to be happy. Being grateful means being thankful. Being mindful means considering, focusing on, and enjoying the experiences of the present moment. Being optimistic means being hopeful about the future.8.Why do Human brains remember negative things more easily?A.Because negative things tend to affect human survival immediatelyB.Because negative things are easy to rememberC.Because negative things are much more important than other thingsD.Because negative things can make people live much happier9.According to this passage, in which of the following can people not find happiness?A.making friends B.doing sports C.playing the violin D.chasing power 10.In the last paragraph, what does author try to tell us?A.We should think more about our future.B.We should be positive in our life and work.C.We should focus on everything in our life.D.We should only enjoy the present moment.11.What does the passage mainly want to tell us?A.Why people remember positive things easily.B.Why people remember negative things easily.C.Some habits that make people happy.D.The habits the people form in their life.The Suez Canal (苏伊士运河),which connects the Mediterranean Sea (地中海) and the Red Sea, opened in 1869. It helps speed world trade between the East and the West. But the man-made waterway has also helped speed the rise of other things, such as non-native species, which have damaged the Mediterranean’s environment and caused native species to disappear.The number of non-native species has risen since the Suez Canal was widened in 2015. The “New Suez Canal” has raised concerns in many Mediterranean countries.Bella Galil is an Israeli biologist who has studied the Mediterranean for over 30 years. She noted that the widening and deepening of the Suez Canal had created a “movingaquarium” of species. These species could make coastal waters almost unusable for human beings. Galil believes the number of invasive species has reached 400, which is twice the number from 30 years ago.Scientists in Mediterranean countries from Turkey, Tunisia to Lebanon share the same concern. But some Egyptians don’t consider the environmental concerns as serious. They said only 5% of the invaders are a problem and that invasive species can be helpful by “replacing species that are overfished”. They don’t think that the widening of the canal is responsible for the increase in invasive species; they say the increase was caused by rising water temperatures and wastewater from ships.The Suez Canal Authority runs the canal. Canal officials say they are closely watching the movements of sea species. They say they are requiring ships to take action to avoid carrying species from one side of the canal to the other. And they are trying to keep salt levels high in the Bitter Lakes to block invasive species out. Galil, however, questions whether these will be enough to protect the native species. “One day we will wake up to a complete and irreversible (不可逆的) change and know that there was something we could have done about it, if only it had been done on time,” she said.12.What does the first paragraph show?A.Seeing is believing.B.Man will conquer nature.C.Let nature take its course.D.Every coin has two sides.13.What does Galil say about the “New Suez Canal”?A.Its environment is worsening.B.It connects Mediterranean countries.C.It is widened to include more species.D.It is to protect endangered native species. 14.What do some Egyptians disagree on?A.The results of overfishing.B.The decrease of native species.C.The cause of the increase in invasive species.D.The meaning of the widening of the Suez Canal.15.What is Galil’s attitude to the Suez Canal Authority’s action?A.Uninterested.B.Doubtful.C.Supporting.D.Understanding.二、七选五For someone who enjoys gardening, gifts for their garden can be very thoughtful and appreciated by them. They can be tools to make gardening easier. Or they can be decorations (装饰品) to make a garden more attractive. 16High quality garden tools can make excellent garden gift ideas. These may be designed with flowers or other gardening pictures on them, or they may be personalized for the gift receiver. Any user-friendly tools for gardeners can be a useful gift. 17Decorations for the garden are some of the more popular garden gift ideas. Animals and small sculptures (雕塑) are generally a good choice. They look good with most types of garden decoration. 18 If a gardener already has a certain style of decoration in his/her garden, try to buy something that fits that style.19 There are many ideas to be found online — using items such as old wine bottles to create lights, for example. The gift receiver will certainly appreciate the time it took to make a gift by hand.Some garden gifts can be very useful. If you know the gift receiver likes birds, for example, you might choose to buy a bird feeder or birdbath for the garden. A stone bench is a more expensive yet very nice gift for a garden as well. 20 These gifts show that you’re really thoughtful.A.That’s why they enjoy gardening.B.Here are some great garden gift ideas.C.It allows gardeners to rest when they’re tired.D.No matter what you buy, they will be appreciated.E.Making something for the garden in person is a nice idea.F.A gardening bag to store these tools can also be a great idea.G.Consider the design of the garden before buying any gifts for it.三、完形填空I spent all of my 30s saying yes.

浙江省嘉兴市一名校2023-2024学年高一10月月考语文试题(原卷版+解析版)

浙江省嘉兴市一名校2023-2024学年高一10月月考语文试题(原卷版+解析版)

嘉兴一中2023学年第一学期高一语文10月阶段性测试卷命题人:高一语文组审题人:高一语文组一、现代文阅读(35分)(一)现代文阅读I(本题共5小题,19分)阅读下面的文字,完成下面小题。

材料一:古人所谓意象,尽管有种种不同的用法,但有一点是共同的,就是必须呈现为象。

那种纯概念的说理,直抒胸臆的抒情,都不能构成意象。

因此可以说,意象赖以存在的要素是象,是物象。

物象是客观的,它不依赖人的存在而存在,也不因人的喜怒哀乐而发生变化。

但是物象一旦进入诗人的构思,就带上了诗人主观的色彩。

这时它要受到两方面的加工:一方面,经过诗人审美经验的淘洗与筛选,以符合诗人的美学理想和美学趣味;另一方面,又经过诗人思想感情的化合与点染,渗入诗人的人格和情趣。

经过这两方面加工的物象进入诗中就是意象。

一个物象可以构成意趣各不相同的许多意象。

由“云”所构成的意象,例如“孤云”,带着贫士幽人的孤高。

陶渊明《咏贫士》:“万族各有托,孤云独无依。

”杜甫《幽人》:“孤云亦群游,神物有所归。

”“暖云”则是带着春天的感受。

罗隐《寄渭北徐从事》:“暖云慵堕柳垂条,骢马徐郎过渭桥。

”“停云”却带着对亲友的思念。

陶渊明《停云》:“霭霭停云,蒙蒙时雨,八表同昏,平路伊阻。

”辛弃疾《贺新郎》:“一尊搔首东窗里,想渊明《停云》诗就,此时风味。

”……同一个物象,由于融入的情意不同,所构成的意象也就大异其趣。

诗人在构成意象时,可以夸张物象某一方面的特点,以加强诗的艺术效果,如“白发三千丈”“黄河之水天上来”;也可以将另一物象的特点移到这一物象上来,如“我寄愁心与明月,随君直到夜郎西”“丛菊两开他日泪,孤舟一系故园心”“长有归心悬马首,可堪无寐枕蛩声”。

这些诗都写到“心”,心本来不能离开身体,但李白的“愁心”却托给了明月,杜甫的“故园心”却系在了孤舟上,秦韬玉的归心则悬在了马首上。

这些意象都具有了“心”原来并不具备的性质。

诗人在构成意象时,还可以某一物象为联想的起点,创造出世界上根本不存在的东西。

“网红〞,本来是“网络红人〞的意思。

然而在当下,“网红〞一词逐渐特指那些依靠秀脸蛋、秀身材、秀美食、秀财富而走红的青年女性。

每当媒体提及“网红〞,几乎都对其加以挞伐,而受教育程度较高的知识阶层,更是一碰到“网红〞就蹙眉,唯恐避之不及。

“浅薄〞“拜金〞“媚俗〞等骂名与“网红〞总是如影随形。

对这些“网红〞的鄙夷和批判,也成为一种主流言论。

“网红〞们走红的方式确实浅薄,粉丝对“网红〞的追捧,也确实物质了些,庸俗了些。

然而,“网红〞们为何能以如此浅薄的方式走红成千上万的年轻人又为何毫无保存地把热情和时间是,献给这些难登大雅之堂的“网红〞?对于这些现象存在的内生合理性,很少见到具备人文关心的考虑,这是不应该的。

其实,只要我们愿意试着去理解“网红〞现象,年轻人追捧“网红〞的真正原因并不难找。

“网红〞之所以可以依靠发自拍、发美食赢得追捧,不就是因为社会上许多下层的年轻人,需要依靠这些东西来满足自己对现实和将来的梦想,让自己的精神生活得到充实吗对于大多已经在社会上立足的成年人,和少数有幸享受较好教育环境的年轻人而言,这种充实精神生活的方式或者许过于廉价,过于媚俗了。

但对社会中大多数下层年轻人而言,“网红〞们那半真半假的姣好面容,逛逛吃吃的悠闲生活,正是他们最真实的内心向往。

对他们来说,更高层次的精神生活,是可望而不可及的,大多数青年都没有时机承受精英式教育,叫他们欣赏曲高和寡的高雅文化,未免有些强人所难,经济上的压力那么让他们难以负担日益高昂的文化消费本钱,进一步挤压着他们的精神空间,在这样的情况之下,他们或者许只能在网络上用这种廉价方式寻求精神生活的满足。

我也是年轻人,我幼时的玩伴中,有不少人也是这些“网红〞的粉丝。

He is a logger who cuts down trees using a knife. The forest where he worked is in the Ondo State in Southwest Nigeria. But many trees in that forest have been lost to too much logging.The 61-year-old father of two said that he could cut down over 15 trees anywhere in the forest,but he would be lucky to find only two now.“During the time of my father, we had big trees but sadly what we have now are just small trees and we don’t even allow them to grow tall enough before we cut them,” Marigi said.After cutting down the trees, Marigi puts markers on them to let other loggers know that he is the owner. The cut-down trees, or logs, are then transported(运输)by waterways and rivers to Nigeria’s biggest city, Lagos.Trees in Nigeria are cut down to open land for farming or to feed the energy need of a growing population. From 2001 to 2021, Nigeria has lost 1. 14 million hectares of tree cover.Months after cutting down the trees, Marigi returned to the forest to tie his 40 logs together so they could be transported. With other loggers, he paid for a boat to pull the logs through waterways from Ondo State to Lagos.They built simple houses on top of the logs to help protect themselves from the weather. Food was shared and they sang traditional songs to cheer themselves up. They did not sleep at night to make sure that the logs would not get away from the boat. The boat stopped at several places to pickup more loggers and their logs. A single boat can transport thousands of such logs.Marigi’s trip ended in Lagos where logs from Ondo State and other parts of the country came together. The logs were then cut and sold to users.4.What can we learn about his father according to Marigi?A.He took good care of the forest.B.He could cut down trees for free.C.He left small trees to later generations.D.He had plenty of big trees to cut.5.How does Marigi show the ownership of the trees he cut down?A.By moving them to his house.B.By making signs on them.C.By putting them near waterways.D.By living on top of them.6.Why did Marigi go back into the forest?A.To collect his woods.B.To plant small trees.C.To look for big trees.D.To open land for farming.7.Why didn’t Marigi and his partners sleep at night?A.Their houses were too small to sleep in.B.They were busy with the woods for sale.C.They protected the woods from being lost.D.They needed to work together continuously.At Phoenix Bikes, a bicycle shop, students are learning to repair bikes. Phoenix Bikes sells bikes to the public at their business in Arlington, Virginia. But it also teaches teenagers how to repair bikes.Most students at Phoenix Bikes start in its after-school “earn-a-bike program”, at middle and high schools in and around Arlington County. Once a week over a 12-week period, students learn repair skills. They learn how to use tools, fix flat tires, correct the wheels, and change gears (齿轮). The first lesson includes splitting the bike, and by doing this, they learn all the parts of a bike.In the first few weeks, they work in small groups to repair a bike given to the shop. The bikes often have missing or damaged parts. The finished bike is then given to a person in need from the community (社区). In the last four weeks of the program, students come to the shop to work on one of the given bikes which they can then take home at no cost.Anthony is a student at nearby Wakefield High School. He just completed his bike. He said it was not in good shape at first but was the kind of bike he was looking for and could be made into something better. He said it had no light, no front tire, and was without a chain, which controls the gears. He said he joined the program to get better at working with his hands and fixing things.Phoenix Bikes is teaching 300 to 400 young people this year. Phoenix communications coordinator Gage said the classes are fun and let students learn with their hands after sitting in the classroom all day at school. He added that bikes are interesting for teenagers especiallybecause they are a means of transportation and freedom. Learning how to fix a bike can also be a fun challenge, he said.8.What does the underlined word “splitting” in paragraph 2 probably mean?A.Putting away.B.Breaking up.C.Unlocking.D.Moving. 9.What do students do with the bikes repaired in the last four weeks?A.They sell them to whoever likes it.B.They use them in the training.C.They keep them for themselves.D.They give them to those in need. 10.Why did Anthony take the trouble to repair the broken bike?A.It was the type of bike he liked.B.It was a must to finish the training.C.He needed to prove his ability.D.He wanted to get real experience. 11.What did Gage think of their program?A.It did good to students’ studies.B.It offered fun transportation to students.C.It was too hard for students.D.It was valuable to students.In February, the U.S. stated that its Mars explorer, Perseverance, landed successfully on the Red Planet. Perseverance is on a task to collect Martian soil and rocks as part of a search for signs of ancient life.Perseverance landed in an area of Mars called Jezero Crater. Scientists believe the area has a large ancient lakebed. NASA considers the area a promising place to find possible signs of microbial life.Perseverance carried to Mars a small experimental helicopter named Ingenuity. In April, NASA said Ingenuity had successfully completed a takeoff and landing on the planet. It said the flight was historic; it marked the first time any flying machines had performed a powered, controlled flight on another planet.In July, British billionaire Richard Branson entered into space on a rocket plane built by Virgin Galactic, the space tourism company he created. Branson joined two pilots and three other task experts on the flight. Virgin Galactic aims to fly private citizens to the edge of space to experience a few minutes of weightlessness and observe the Earth.A little over a week later, American billionaire Jeff Bezos flew to the edge of space on a rocket built by his company, Blue Origin. Three other people took the quick trip with him: Bezos’ brother, a Dutch teenager and an 82-year-old pilot.The flights by Branson and Bezos officially started a new industry that promises anycitizen the chance to visit space. Such trips will be costly, however. Virgin Galactic’s price for a single flight is $250,000. Blue Origin has not publicly announced its price. Both businesses have built operating bases, called spaceports, in the countryside areas of the U.S.And earlier this month, Japanese billionaire Y usaku Maezawa arrived at the International Space Station (ISS), their destination where they stayed for 12 days. The businessman arrived along with an assistant aboard a Russian Soyuz spacecraft. The price of that trip has not been made public, but some reports guess it cost up to $50 million.12.What is Virgin Galactic’s goal?A.To search for life in space.B.To draw people’s attention to space.C.To develop space tourism for the public.D.To support space exploration programs. 13.What do we know about Richard Branson and Jeff Bezos?A.They traveled in space with their family.B.They went to the same place in space.C.They tried to serve tourists in the countryside.D.They rode a spaceship built by their own company.14.What is secret about the Japanese billionaire’s space travel?A.Its cost.B.Its destination.C.Its travel period.D.Itstransportation.15.Which is the most suitable title for the text?A.Expensive Space Tourism in the Future B.Signs of Ancient Life Discovered on MarsC.Traveling in Space, Billionaires’ Game D.Progress on Mars and Rise in Space Tourists二、七选五How to Grow Plants with Little SunSome people might think that growing plants without much sun is a difficult, if not impossible, task. However, that is not true.What type of shade (背阴处) do you have?The first step is understanding the type of shade you have. This is based on the amount (数量) of time that the sun shines on the area. 16 They are:• part shade (3-6 hours of direct sun, usually in the morning)• full shade (less than 3 hours of direct sun)• deep shade (sunlight rarely, if ever, gets through trees or past structures like buildings) Buy the right plantsWhen you know your shade conditions, find plants that suit them. 17 You can also research that information online, in books or magazines. Experts at gardening stores are other sources of information.And don’t forget your gardeners nearby. When walking around a community garden or your neighborhood, take note of plants growing in shady areas. Talk to the gardeners. 18 Ways to increase lightThe gardening expert adds that painting nearby structures white mirrors sunlight. Glass and mirrored objects can also mirror light around the garden. If possible, carefully cut some tree branches (树枝). This lets more sunlight reach the ground.What to plant?Search for the low-light plants suitable for your area. 19 Vegetables like tomatoes need a lot of sun. But leafy greens actually grow better in part shade.As for pests (害虫), some kinds like shade gardens. But most other pests are less of a problem in low-light conditions. 20 That is, you will feel less hot while gardening!A.There are three main types of shade.B.Learn about their successes and failures.C.Do not give up growing plants you can eat.D.Deep shade is the most challenging for gardeners.E.This information is available where plants are sold.F.Note how many hours of direct sunlight reaches the ground.G.There is another good thing about gardens with less sunlight.三、完形填空I walked quickly over to the check stand, pulled some 26 out of my bag and showed it to the cashier.

)8.D(A项“科学家们在逆境条件下”不对,原文的意思是这些寿命长的果蝇品系与延长寿命有关的基因在逆境条件下得到了表达,功能得以发挥。

B项原文说“有些基因改变后将导致代谢活动缓慢,活力降低”而不是“人或其他生物体的活动缓慢、活动收入低尽然导致其基因的改变”。

一、现代文阅读(39分)(一)论述类文本阅读(本题共3小题,9分)阅读下面的文字,完成1-3题。

如果说闻一多是新月派诗歌的元帅型人物,新月派的副帅就是徐志摩。

他们的主张虽然差不多,但写起诗来,他和闻一多相比还是有比较大的风格上的差异。

徐志摩跟闻一多相同的是他也喜欢讲点道理,讲点理论,向人炫耀他的学历。

但他那些文章看来看去,你总觉得他不一定是一个好学生,道理讲得比较差。

在新月派里,论理论修养他不如闻一多,不如梁实秋,这也未必就是缺点,他的性格就是不喜欢枯燥、繁琐的理论。

喜欢徐志摩诗歌的人一般以青少年为主,在中文系待着,二年级以上的人恐怕就没有喜欢徐志摩的了。

徐志摩的诗给人的感觉是更加依靠灵感,所以在当时被看成是天才诗人。

徐志摩的确是个天才,他自己也说,他写诗是靠灵魂深处来的一股暖意,这没法用道理来解释。

胡适有自己的诗歌理论,郭沫若有自己的诗歌理论,闻一多也有,但徐志摩所依靠的就是灵魂深处来的一股暖意。

其实徐志摩最好的诗不是《再别康桥》,比如他的《沙扬娜拉》写得更好。

这首诗非常短,不整齐,不押韵,好像不符合新月派的“三美”主张,但是你读起来有一种内在的整齐,内在的韵律,它的表达形式和它的表达对象完美地统一了。

另外有一首既整齐又自然的诗叫《雪花的快乐》,可以说既能代表徐志摩,也能代表新月派。

这首诗一共有四节,每一节的形式都一样,整齐和不整齐是搭配的。

这首诗每一节选的韵也是很见匠心的,潇洒的时候用的是花韵,飞扬的时候用的是比较明亮的韵,最后落到姑娘身上的时候变成消融,变成鼻音结尾。

这首诗几乎无可挑剔,能够代表徐志摩的艺术成就。

绝。

”我初听这话。

未能信受。

继而一想,觉得大有道理!古人作文,的确言简意繁,辞约义丰,不像我们的白话文那么噜里噜苏。

回想古人的七绝和五绝,的确每首都可以作为一篇随笔的题材。

例如最周知的唐诗:“去年今日此门中,人面桃花相映红。

人面不知何处去,桃花依旧笑春风”、“少小离家老大回,乡音无改鬓毛衰。

儿童相见不相识,笑问客从何处来”这两个题材,倘使教我来表达,我得写每篇两三千字的两篇抒情随笔。

“昨日入城市,归来泪满巾:遍身罗绮者,不是养蚕人”、“长安买花者,一枝值万钱;道旁有饥人,一钱不肯捐”这两个题材,倘教我来表达。

我也许要写成——倘使我会写的话——两篇讽喻短篇小说呢!于是我佩服这位老前辈的话,表示衷心地接受批评。

三十年前这位老前辈对我说的话,我一直保存在心中,不料今天同窗外的“爆炒米花”相结合了,我想:原来我的随笔都好比是爆过、放松过的年糕!1 第二段主要采用了什么表达方式?在文中起什么作用?(6分)2 结合全文,分析本文的写作目的是什么最能表现作者的思想感情是哪一句??(6分)3 文中使用类比,即把爆过、放松过的年糕比喻成用白话文写的随笔,而把没有爆过的年糕比作是言简意繁的古文,这样写有什么作用?(6分)二.“立德树人”类作文。
