盐城中学·苏州中学·扬州中学·常州中学2021年G4学校高三教学情况期末调研语文2021.01一、现代文阅读(一)现代文阅读Ⅰ(本题共5小题,19分)阅读下面的文字,完成1-5题。
材料一:高尔基说:“一般说来,神话乃是自然现象,对自然的斗争,以及社会生活在广大的艺术概括中的反映。
”这就说明了神话的产生,是基于现实生活,而并不是出于人类头脑里的空想。
所以当我们研究神话的起源,古代每一时期的神话所包含的特定意义等诸如此类的问题的时候,都不能离开当时人类的现实生活、劳动和斗争而作凭空的推想。
中国神话的“源”,求诸古籍记载,自然最早莫过于属于巫书性质的《山海经》。
它实际上是从战国初年到汉代初年这一段长时间内众多无名氏的作品,初步推断可能是楚地和巴地的人所作,有巫师和文人参与其事。
但是追本溯源,还应当推寻到传说中夏禹、伯益那个历史时代。
好些神话故事经由那个时代的酋长而兼巫师身份的人物,口头直接传承下来乃是大有可能的。
根据我的研究,万物有灵论时期已是神话的初步发展阶段,《山海经》所记载的神话,大都属此阶段。
但在前万物有灵论时期,即已有萌芽状态的神话产生了。
这个时期相当于马克思在《摩尔根﹤古代社会﹥一书摘要》中所说的蒙昧时期的中级阶段,亦即以生产方式为分期的旧石器时期的中期。
这个时期产生的神话,多以动植物为主要描述的对象,尤其着重叙写的是动物,性质和后世的童话、寓言相近。
我称这个时期的神话为活物论神话,以别于万物有灵论时期的神话。
那时候的人们,刚从动物分离出来不久,还存在着物我混同的原始思维的心理状态,视眼前的万物,不论是动物植物,或山川日月星辰风雨云霞等,都认为是和自己一样有生命有意志的活物,由此而在集体无意识中产生的叙写它们之间或它们与人类交往的故事,就是最早时期的神话——活物论神话。
原始的宗教思想萌芽于此,图腾主义也由此而来。
但《山海经》保留这种神话已经不多了,只还有两三个残片遗存其中,较多的是保留在先秦时代的寓言里。

一、单项选择题:共15题,每题2分,共30分。每题只有一个选项最符合题意。
1.下列关于细胞中化合物的叙述,错误的是()
A.糖原、纤维素酶和脂肪酸的组成元素都主要是C、H、O
B.细胞中合成淀粉、蛋白质及核酸的过程都会产生水
2、利用血球计数板在显微镜下直接计数是一种常用的细胞计数法,这种方法可以直接测定样品中全部的细胞数目,所以一般用于单细胞微生物数量的测定,由于血球计数板上的计数室盖上盖玻片后的容积是一定的,所以可根据在显微镜下观察到的细胞数目来计算单位体积的细胞的总数目。
D、碘是甲状腺激素的合成原料,故通过“食盐补碘”可以有效预防“大脖子病”的发生,D正确。
故选A。
2.下列有关利用传统发酵技术制作果酒、果醋及泡菜的叙述,正确的是()
A.发酵原料和发酵装置都需进行灭菌,以防止杂菌污染
B.发酵用菌种的细胞呼吸类型及生物膜系统的组成都是相同的
C.三者的发酵液都主要是因为产生了大量二氧化碳而呈酸性
【详解】A、果酒、果醋及泡菜的制作过程中的产物(酒精、醋酸形成的酸性条件、乳酸形成的酸性条件)能抑制杂菌的繁殖,而且传统发酵技术制作过程中的菌种一般来源于原料中,因此发酵原料不需要灭菌,否则会杀死菌种,A错误;
B、由分析可知,发酵用菌种的细胞呼吸类型不相同,发酵菌种有酵母菌真菌,也有醋酸菌、乳酸菌细菌,真菌有生物膜系统,细菌只有生物膜(细胞膜),B错误;
B、一个mRNA上结合多个核糖体,有利于细胞快速合成相同的蛋白质,提高了翻译的效率,B错误;
C、一种氨基酸可能对应多种密码子,这样使生物体具有一定的容错性,提高翻译效率,C正确;
D、DNA分子中,GC之间能形成三个氢键,故细胞生物DNA中GC含量较高,DNA更稳定,有利于生物生活在较高温度的环境,D正确。

Now the island has a new luxury resort Caerula Mar Club- which opened this February. The once-abandoned property was discovered by a well-known HGTV reality star couple who transformed it into a hotel. The Canadian design duo Bryan and Sarah Baeumler were vacationing in the Bahamas in the summer of 2017 when they discovered a once-abandoned resort. They instantly decided to purchase it with hopes to transform the 10-acre beachfront property into a luxury hotel.However, they had no idea how much the investment would end up costing them. Here most supplies had to be shipped in, and the property was in bad shape. The budget for the remodelling should be around $ 4 million, but they've spent well over $ 10 million. What's worse, in the fall of 2019, category 5 Hurricane Dorian hit the Bahamas, and their employees and friends were affected.Finally, several months later, as they prepared to open the resort to the public, the Coronavirus pandemic (大流行病)struck. They'd just been fully booked throughout the fall and winter months when the new disaster stopped everything as the Bahamas were put on lockdown.With tourism opening up again, new plans are now for an October launch, but they're just taking things one day at a time. "I think at the end of this pandemic, well find many people are searching for a different experience,” says Bryan. "Instead of crowding into large resorts, they'll be going to properties where they can meet people, connect with the locals and experience nature. Our hotel is just such a place.”Now the couple is focusing on the future while creating new development for visitors. “We certainly have plans to responsibly and sustainably develop the island that will help support the local economy says Bryan.4.What can we learn from the first paragraph?A.Life on Andros Island is fast-paced.B.Andros Island is lightly populated.C.The couple built the hotel as planned.D.The couple found the luxury hotel accidentally.5.What challenges did the couple face while building the hotel?A.Finances and disasters.B.The bad local economy.C.Poor health conditions.D.Local people's objections. 6.What, is Bryan's attitude towards their hotel?A.He thinks it's not worth the price.B.He is worried about it.C.He is confident about it.D.He thinks it should be reevaluated. 7.What is mainly implied in the last paragraph?A.The sustainable ways of developing the island.B.The political effects of the hotel on the island.C.The promising future of the tourism on the island.D.The couple's determination to contribute to the island.In the past few decades, great changes have taken place in the literary world. With the time changing, Chinese university students show a typical characteristic in their after-school reading and this reflects the changes of thoughts and the quality of young people.The 1960s was the time for admiring heroes.

At that time, foreign and Chinese masterpieces, especially works of Hugo and Shelley were the books young people often read.A survey named “The book that impressed you most during 1985 to 1989” indicated that Jin Yong's works ranked the second and works of Qiong Yao and San Mao the sixth.In addition to romantic fiction and martial arts fiction, a new type of books — science fiction became popular among the male students in the 1990s. Apart from that, contemporary masterpieces including Chinese novels such as White Deer Plain, and foreign masterworks like War and Peace and The Thorn Birds were also popular.8.What is mainly described in the second paragraph?A.Real heroes in the 1960s.B.Foreign works in the 20th century.C.The role models in Chinese college students’ eyes.D.The popularity of heroic books among Chinese college students.9.What does the underlined word “industrious” in Paragraph 3 mean?A.Smart.B.Hard-working.C.Casual.D.Absent-minded.10.What can we learn from the text?A.University students in the 1960s read more than those in the 1970s.B.Female university students liked science fiction most in the 1990s.C.College students could choose to read from many books in the 1980s.D.The Thorn Birds was the most popular novel in the late 20th century.11.Which can be a suitable title for the text?A.Life Expectations of Chinese University Students.B.What Books University Students Have Read Most.C.Great Changes Have Taken Place in the Literary World.D.Changes in Spare-time Reading for Chinese University Students.Do you find yourself unable to go more than 15 minutes without reaching into your pocket, pulling out your smart phone and checking your e-mail or WeChat? Don't panic. You are hardly alone. A recent survey shows that smart phone users have developed "checking habit"—frequently checks of e-mails and other Apps. The checks normally lasted less than 30 seconds and were often done every 10minutes.On average, the study subjects check their phones 34 times a day. And the strangest part is that they don't even realize they are doing it. "I hadn't told my hand to reach out for the phone. It seemed to be doing it all on its own," wrote Elizabeth Cohen, a medical correspondent for CNN who watched her right hand sneaking away from her side to grab herphone while sitting on the table at dinner with friends.Loren Frank, a neuroscientist at the University of California, San Francisco (UCSF), explains that checking smart phones is rewarding in some way. "Each time you get an e-mail, it's a little bit exciting, because it means a positive feedback that you're an important person," Frank told CNN. Once the brain becomes used to this positive feedback, reaching out for the phone becomes an automatic action you don't even think about consciously, said Frank. Professor Clifford Nass of Stanford University added that constantly checking your smart phone is also “an attempt to not have to think hard but feel like you are doing something".However, every coin has two sides. This habit can cause problems. Study show that whenever you take a break from what you are doing to check your smart phone, it is hard to go back to your original task, according to Adam Gazzaley, a neurologist at UCSF. That's not the worst. A survey by South Korean marriage consulting agency Duo earlier this year shows that smart phones are destroying intimate relationships, reports The Korea Herald (韩国先驱报). About half or the respondents said they had had fights with their boyfriend or girlfriend because of smart phones. And 32.8 percent of them fought about smart phone obsession. In this respect, checking smart-phones at regular intervals is a bad habit. But just as an old saying goes, "Bad habits die hard.”So to get rid of the checking habit, Cohen suggests establishing phone-free times and zones.12.What is the most unusual part of the study subjects?A.The times of phone checks.B.The lasting time of phone checks.C.The unawareness of checking phones.D.The high frequency of checking phones.13.What does Loren Frank think of checking smart-phones frequently?A.It is worthwhile in some way.B.It is necessary to think hard.C.It is unimportant for those busy people.D.It is likely to cause neurological diseases.14.Which of the following is the worst effect of the “checking habit” has on phone users? A.They might not have a good rest.B.They would be taken in by other people.C.They might get distract from their work.D.They would lost time to keep close relationship.15.What is the main purpose of writing this passage?A.To introduce a smart-phone consumption survey.B.To present the obsession with smart-phone checking.C.To list the advantage of smart-phone checking habit.D.To offer the ways to quit smart-phone checking habit.二、七选五We automatically assume that as adults, we’re wiser than when we were children. However, actually we can learn a lot from our childhood self. For example, we can learn to develop optimism about the future. Do you remember how excited you used to be just before Christmas? ___16___ Reintroduce that childlike wonder into our daily experiences.We can learn to dream big and imagine the impossible.

2021届江苏省常熟中学高三语文上学期期末试题及参考答案一、现代文阅读(36分)(一)现代文阅读I(9分)现代文阅读(19分)风语胡炎风,卷着梦的香气,一阵一阵,撩得人难受。
村头老杨树下,他蹲着,目光铸在密匝匝的枝叶间。
叶片上,昨夜的梦还在跳荡,金光灿灿,晃得人眼晕。
抬手捋一把,那叶子全是钱,新崭崭香喷喷,揣进怀里,平素蔫软的腰杆硬是生生挺得笔直。
身前,烟屁股滚了一地。
最后一支抽尽,再把烟屁股捡起来,点燃,狠狠地补几口。
心,也给灼得火烧火燎:这财,别人发得,我怎就发不得?“爹!”进家,他叫。
“弄啥?”爹不看他,手里的锤子起起落落,只顾自加固他的锄头。
“钱……我得用。
”爹的手停了,翻他一眼:“那是留着给你娶媳妇的。
”“媳妇不急,钱急。
”他给爹敬支烟。
“到底弄啥?”“正事,别问!”他把字咬得很重。
爹不再言语。
这是他唯一的儿。
儿一贯是老实本分的,他不能不依他。
叔、伯、舅、姑……挨个借了个遍。
然后村西的、村东的,南头的、北头的,挨门槛进,讨好的笑,把一张脸都给拉伤了。
“就你,也做白日梦?”村人的眼里,满是鄙夷和不屑。
他依旧笑,心里却骂:“狗眼看人低,等着瞧!”购置设备、联系货商、组织人手……第一批成品终于出炉,没想到,事儿来了。
一块黑转,拍晕了他:“敢跟老子抢生意?”他摸索着爬起来,捂着流血的后脑勺:“疤哥,我不懂事,您老人家大人大量,抬抬手,给兄弟条生路。
”疤哥叉着腰:“这砖,挨得亏不亏?”“不亏。
”“想不想再挨一砖?”“疤哥,您说笑。
”“识相点,拜老子的山头,有钱大家赚。
”“懂了,疤哥,您是爷。
”“好孙子。
”疤哥又朝他后脑勺拍了两下,这次不是砖,是手。
有了疤哥,生意竟出奇地红火。
人前人后,便再也不是从前那个“老实蛋子”,好烟潇洒地掷过去,说话便有了十足的底气。
村人的眼光,也把他托了起来。
唯有爹,一张瘦瘦的黑脸平静得像十月的秋空,怎也拧不出个表情。
或许在他心中,只有锄头、泥土和庄稼,那是他生命的全部。

APerhaps you are a corporate manager who is about to attend a few business dinners in China, or maybe you are meeting your significant other' s family at a dinner in Shanghai. Either way, you can be sure that lots of drinking is involved during these Chinese social events.What you will be drinking.Baijiu- Also called sorghum wine, baijiu is the drink of choice for business dinners in China.The most popular brand of baijiu is Maotai , which can be as strong as 60% alcohol-by-volume(compared to an average vodka at 40% ABV).Red wine-Red wine has increased in popularity at Chinese dinner tables in recent years along with the rising interest in luxury goods.Beer-Popular Chinese beer brands include Tsingtao and Harbin Beer, which are crisp, refreshing lagers(淡啤酒)that can cool the burning sensations from drinking baijiu.Courage, quantity, and qualityIt's perfectly all right if you get drunk, and if you leave sober, your hosts might think they've failed to show the proper hospitality.The bottom line is, it's best if you drink whatever they give you. This is called jiudan-“drinkcourage". Of course, having jiudan doesn't automatically mean you have a good jiuliang-“drinking capacity" or the ability to hold your drink. But this really doesn't matter, as long as youhave good jiupin-“drink manners" or the way you behave when drunk. Ideally you'll have all three, but if you don't, the first one is the most important.General etiquetteWhen clinking glasses, the junior people should always hold their glasses lower than those of senior folks. Also, if you are late for the party, you are expected to punish yourself by drinking.Lastly, it is considered extremely rude to refuse a drink after someone toasts you. Of course,“drying your glass" is considered the utmost respect at the dinner table.21. What is beer more likely to serve as at Chinese dinner tables?A. Appetizer.B.Primary drink.C.Secondary drink.D. After-dinner drink.22. What policy should you follow when drinking in China?A. Under no circumstances should you get drunk.B. If you don't love the drink offered, you can say no.C. You have to get drunk to show respect for your host.D.Drink courage matters most when you drink with others.23. What is the proper behavior for a young adult over 18 at Chinese dinner tables?A. Refusing a drink if you don't want it.B. Drinking yourself under the table when late.C. Holding your glass lower when toasting seniors.D. Toasting seniors as many times as you can.BEven with wonderful friends, family and a partner, I don't always want to be surrounded by people. “Table for one? Or will someone else be joining you?” A dinner reservation for one person never fails to raise a few eyebrows. I actively choose to spend time alone when possible. But not everyone has the luxury of choosing to be alone, of course, many are forced into one-on-one time because they have no one.But for those of us who spend our days surrounded by colleagues in the workplace, our evenings and weekends with family, friends and partners, all the while being constantly bombarded by WhatsApp,social media and email, time to ourselves can be a rare treat. Time to yourself not only gives you the chance to do practical things you don't normally get round to but also the activities your pals don't want to do. In a less real way, spending time alone also allows-or perhaps forces- you to sit with your own thoughts, to think about things that might normally be drowned out by conversation and the noise of companionship. When you're alone you get time to think without purpose.It is worth noting that I'm a real introvert(性格内向者),so perhaps sitting alone with my thoughts-refilling my energy reserves-might just be indulging personality traits that others don't have. But I believe more people could benefit from it.Given this constant social conditioning since childhood that we should be surrounded by people , it's no wonder many hesitate to press forward at the idea of spending time alone-a sign we've failed at climbing that social ladder. And if you're an extrovert who gets their energy from other people, this must be even harder. But as someone who has come to love spending time alone, even when there are many wonderful souls in my life I can spend time with, I wish more people would give solo a go.Reservation for one, please.24.

Until day 14, there was little difference between the two groups. But after that, the data showed a 33% fall in infection rates among those who had already been vaccinated compared with those who hadn't. Clalit noted that the number of people infected was statistically significant, but said it wouldn't release final numbers until its study is published.Pfizer says people must receive both doses of the vaccine for it to be fully effective. In Pfizer's trials, the vaccine was shown to take about 12 days before it started to protect people. The Clalit study suggests that the first dose could reduce infections among those vaccinated as early as two weeks after injection.Israel, like many other countries, has given priority to those over 60 in the first stage of its vaccination drive,making the group the best fit for study. Nearly three out of four people in this age group have received the first dose of the vaccine since Israel's campaign began on Dec.20.Israel has committed to providing Pfizer with real-time data about their vaccine,from effectiveness to side effects,which Israeli officials said helped it obtain early supply from the vaccine maker. Separately,Israel's Health Ministry published data about side effects from the vaccine, saying they were similar in frequency and character to other vaccinations given to its people.28.What does the underlined part "hit that mark" refer to?A.

It will play a decisive role in further study.D. It is of great importance in terms of statistics.30. Pfizer agrees to put Israel on its priority list on condition thatA. Israel provides timely feedbackB. Israel vaccinates its seniors firstC. Israel reports side effects regularlyD. Israel publishes its data as instructed31. What can be a suitable title for the text?A. The Pfizer Vaccine Proves SafeB.Old People Get Vaccinated in IsraelC. Data Suggests Vaccine EffectiveD. Israel Succeeds in Fighting Covid-19DFriday was"Chatty Bus day", an experiment aimed at getting people to talk to each other on public transport. This is not an idea that would appeal to those who commute in the rush hour, because there is a smaller distance within which it's just as uncomfortable to talk. Elbow(肘) room is a precondition for sociability. It is no coincidence that the first truly personal music player, the Sony Walkman, was invented in Japan where the commuter trains are literally crowded with people.We will also not talk to strangers who are physically too far away, of course. No one wants to shout their small talk. Only on country buses or similar unhurried and uncrowded forms of public transport can people reach out to their neighbors, confident that they are doing so from a position of strength and autonomy.For all these drawbacks, the idea of talking to strangers is still a good one, and the promotionof sociability is good for society. Although it does seem to be a general rule that people are friendlier the fewer there are of them and more hostile and indifferent as cities get more crowded, there are still considerable cultural variations. And there is evidence that friendlier places are also healthier, and their inhabitants happier.It is true that the apparent loneliness of many people on public transport is a false impression.Many will be caught up with conversations with distant friends on their phones; some will be talking to the people in books. Some may be in willed solitude with their headphones. But there are always people who would be interested in an unexpected conversation with a stranger. This need not go on for too long.It is not large and possibly life-changing conversations that are what most people in loneliness miss most. What they really need is not deep thought but superficiality. The kind of conversation that you could have with anyone reminds you that you yourself might be anyone. It is a release from the prison of the self, which is where lonely people serve their sentences, uncertain whether they ever can be paroled(假释)。
