This would be her first trip with her father on what he had always been famous for.Larry first began diving when he was his daughter’s age. Similarly, his father had taken him along on one of his expeditions. Since then, he had never looked back. Larry started out by renting diving suits from the small diving shop just along the shore. He had hated them. They were either too big or too small. Then, there was the instructor. He gave him a short lesson before allowing him into the water with his father. He had made an exception. Larry would never have been able to go down without at least five hours of theory and another similar number of hours on practical lessons with a guide. Children of his age were not even allowed to dive.After the first expedition, Larry’s later diving adventures only got better and better. There was never a dull moment. In his black and blue suit and with an oxygen tank fastened on his back, Larry dived from boats into the middle of the ocean. Dangerous areas did not prevent him from continuing his search. Sometimes, he was limited to a cage underwater but that did not bother him. At least, he was still able to take photographs of the underwater creatures.Larry’s first expedition without his father was in the Cayman Islands. There were numerous diving spots in the area and Larry was determined to visit all of them .Fortunately for him, a man offered to take him around thedifferent spots for rry didn’t even know what the time was, how many spots he dived into or how many photographs he had taken.The diving spots afforded such a wide range of fish and sea creatures that Larry saw more than thirty varieties of creatures.Larry looked at his daughter. She looked as excited as he had been when he was her age. He hoped she would be able to continue the family tradition. Already, she looked like she was much braver than had been then. This was the key to a successful underwater expedition.4. In what way was this expedition different for Larry?A. His daughter had grown up.B. He had become a famous diver.C. His father would dive with him.D. His daughter would dive with him.5. What can be inferred from Paragraph 2?A. Larry had some special right.B. Larry liked the rented diving suits.C. Divers had to buy diving equipment.D. Ten-year-old children were permitted to dive.6. What can be learned from the underlined sentence?A. Larry didn’t wear a watch.B. Larry was not good at math.C. Larry had a poor memory.D. Larry enjoyed the adventure.7. What did Larry expect his daughter to do?A. Become a successful diver.B. Make a good diving guide.C. Take a lot of photo underwater.D. Have longer hours of training.CMy family and I never talked about school as the ticket to a future. I was in theclassroom, but I wasn't there to learn to write, read or even speak. When it was my turn to read, I wanted to hide. I was 13 years old, but I already hated being who I was.I had an English teacher, Mr.Creech, who knew I couldn't read. In one of my first lessons the teacher said that anyone who had a reading age below six had to stand up. I felt so embarrassed. But at the same time, it made me realize that I needed to change the situation. I was determined it wouldn't happen again. Later that day, Mr.Creech encouraged me and promised he would try his best to help me learn to read. From then on, I never gave up practicing reading.Then when I was 41 years old, one day, I planned to fly back toTexasto visit my friends and family. On my wayfrom the airport, I saw Mr.Creech buying himself a drink. I rushed over and reached into my pocket to pay for him. “Do I know you？” he asked. “Yes, sir, you do know me，” I answered excitedly. “My name is Anthony Hamilton. You taught me English.” The look on his face told me that he remembered the boy he'd once encouraged.“I'm so glad I had a chance to see you，” I said. “And Mr.Creech, I have great news to share.” I told him I had learned to read. But that wasn't all. I had become a published author and an active speaker. “The next time you get another Anthony Hamilton in your classroom, please encourage him to read as well，” I added.The experts say what once worried me has a name：dyslexia(诵读困难). But I can tell you it was a lack of desire for education.8. Why did the author want to hide?A. Because he felt sorry for himself.B. Because he hated being laughed at.C. Because he couldn't read at all.D. Because he didn't have a ticket.9. Which of the following could best describe Mr.Creech?A. Considerate and dutiful.B. thoughtful and enthusiastic.C. Emotional and devoted.D. Friendly and wise.10. Why couldn't the author read before meeting Mr.Creech?A. Because his reading age was not long enough.B. Because his parents didn't teach him how to read.C. Because he was afraid of reading before the class.D. Because he didn't have inner driving force to learn to read.11. What can we infer from the passage?A. Mr.Creech taught two students called Anthony Hamilton.B. The author had become a published author and an active speaker.C. Dyslexia was just the reason that made the author unable to read.D. The author was grateful to Mr.Creech.DScientists have discovered a new behaviour among bumblebees that tricks plants into flowering early.When lack of pollen, bumblebees will bite little by little on the leaves of flower-less plants. The damage seems to fool the plant into flowering, sometimes up to 30 days earlier than normal.With their hairy appearance and special sounds, bumblebees are hard to miss in gardens all over the world. Their hairy bodies make them excellent pollinators for crops like tomatoes and blueberries. They are among thefirst bees to appear each year and work a long season.But despite their key role, bumblebees, like many other pollinators have seen their numbers decline suddenly in recent decades. One recent study pointed to climate change, reporting that an increasing number of hot days in Europe andNorth Americawas raising local bumblebees extinction rates.But researchers have now made a discovery about bumblebees that could have something to do with their long term survival. Scientists inSwitzerlandfound that when the bumblebees were out of pollen, they started to bite on the leaves of plants that hadn't yet flowered. They used their mouths to cut clearly-shaped holes in the leaves. But the creatures didn't eat the material or use it in their nests.The damaged plants responded by flowering earlier than normal--in some cases up to 30 days ahead of schedule. Researchers also found that the bee damaged plants flowered 30 days earlier than undamaged plants and 25 days earlier than ones damaged by the scientists.“I think everything that we've found is consistent with the idea that the bumblebees are damaging the plants and that that's an adaptation that brings flowers earlier and that benefits the bees,” said Dr Mark Mescher, one of the authors from ETHZurich.12. How do bumblebees fool plants into flowering earlier?A. By making use of the hot weather.B. By putting the false flowers on the leaves.C. By attacking the leaves of flowerless plants.D. By taking away the pollen from the other flowers.13. What's bumblebees’ key role?A.Making plants flower early.B. Spreading pollen to flowers and plants.C. Sending information about weather change.D. Finding out whether the plant has flowers.14. What has happened to bumblebees in the past the years?A. They are becoming homesick.B. They are not as friendly as before.C. There is a sharp decrease in number.D. They have been busy year by year.15. What's Dr Mark Mescher's attitude towards the behaviour of bumblebees?A. Uncaring.B. Skeptical.C. Tolerant.D.

When my father married my mother in 1943, he gave my mother a 1937 crown coin and told her to keep it in the back of her purse and not to spend it． This would mean that shealways felt that she was protected and would always have money if she really needed it．When I was married in 1970 my husband who had heard this story, obtained a 1937 crown coin for me and I have always kept it in my wallet, and I have always had enough for my needs．A friend recently fell on hard times, partly through external （外部的）circumstances and partly through poor planning． Friends and I have loaned her money, paid her bills, given her food, and even tried to teach her budget techniques, but none of them has been a solution． She has just slipped deeper and deeper into financial trouble and depression．Last week she looked pale and unwell, very depressed and hopeless, very sad for a friend to see and I then thought about how the crown coin, a physical reminder of another's care and love had protected me, so I went to the bank for a ＄100 dollar﹣bill．I told my friend the story and asked her to keep the ＄100 in the back of her wallet． It turned out that she didn't have a wallet, so she put the money in a little pencil case where she kept her coins． She immediately felt better﹣"I feel rich, and thank you for being a good friend, " she said, and we were both a bit teary．I went home and remembered a little wallet I had that I'd never used, and thought, "I'll give that to my friend． " I opened it, and inside, found ＄100．（1）What did the 1937 crown coin from the author's father mean to her mother？________ A His concern for her． B His pity and protection for her． C His care and love for her． D His pride and respect for her．．（2）Where did the author's friend keep the ＄100 dollar﹣bill？________A In the back of her wallet．B In a little pencil case．C In the pocket of her raincoat．D In the layer of her suitcase．．（3）What can be inferred from the last paragraph？________A The author became rich all of a sudden．B The author's friend would receive a wallet as a gift．C The author's friend was not touched by her story．D The author felt uncomfortable when receiving the bill．．（4）What can be the best title for the text？________A A crown coinB The help to a friendC A hard lifeD A gift from my father．3. Encouraging children to use gestures as they think can help them come up with more creative ideas, according to new research．"Our findings show that children naturally gesture when they think of unusual ways to use everyday items, "says psychological scientist Elizabeth Kirk． "When we then asked children to move their hands, they were able to come up with even more creative ideas． " "Gesturing may allow us to explore the properties（特性）of the items ﹣ for example, how the item could be held, its size, its shape, etc．﹣ and doing so can help us come up with ideas for creative uses, " Kirk explains．In their first study, the researchers compared the creativity of children who spontaneously （自发地）gestured with those who either did not or could not gesture．A total of 78 children, aged 9﹣11, saw a series of images of ordinary items, such as anewspaper, a tin can, and a kettle． The researchers asked the children to look at each image and list as many uses as they could think of． A group of participants completed the task twice ﹣ on one version of the task, they wore mittens（连指手套）that limited their ability to gesture．Restricting children's ability to gesture did not affect their ability to come up with creative uses for the objects; Children who were free to gesture produced about the same number of ideas as those who wore the mittens and could not gesture．In a second experiment, 54 children completed the same alternative﹣uses task． In some cases, children gestured normally; in other cases, the researchers encouraged the children to"use your hands to show me how you could use the object in different ways"．The encouragement worked: Children who were specifically encouraged to gesture produced a greater number of creative uses for the objects than did the children who were not given any special instruction．"Our findings add to the growing body of evidence showing the significant role of gesture in thinking and have applications to the classroom, " Kirk concluded in their paper．（1）What did the researchers intend to find out in the first experiment？________A The number of creative ideas the children could think of．B How the children would explore the properties of the items．C Whether encouraging gesture would help to produce more new ideas．D The difference between thinking with gestures and without gestures．．（2）Why were mittens used in the experiment？________A To restrict gestures．B To limit creative thinking．C To test the ability to gesture，D To increase creative ideas．．（3）When did the children think of the most new ideas？________A When wearing mittens．B When encouraged to gesture．C When naturally gesturing．D When not using their hands．．（4）What would be the best title for the text？________A Communicate with GesturesB Think with Your HandsC Use Everyday Items CreativelyD Make Gestures when Necessary．4.

合肥市部编版2020届高三语文调研性检测试题(含解析)
合肥市2019届高三调研性检测语文试题阅读下面的文字，完成下列小题。
分享经济是一种新兴业态，指人们将海量、分散、闲置的社会资源通过一定平台集聚起来并反复使用，以更好地实现供需匹配，创造新的商业价值。
对分享经济的理论研究可以追溯到上世纪80年代。
进入新世纪之后，分享经济模式在实践中逐步形成和发展起来，但主要是纯粹的无偿分享、信息分享。
2010年前后，随着一系列实物分享平台的出现，分享开始建立在有偿的基础之上，且物品使用权会发生暂时转移。
这一变化，使分享经济获得了巨大的发展空间和活力。
伴随“互联网+”战略的大力实施，一批基于移动互联网的创新型分享经济平台脱颖而出。
目前，分享经济已成为移动互联网消费的新主角。
据不完全统计，2016年，我国分享经济市场交易规模达到2.4万亿元，同比增长超过1倍。
基于移动互联网的分享经济通过细分市场对传统产业的闲置资源进行优化利用，推出了出行分享、住宿分享、二手交易、众包物流、服务众包等商业模式，在一定程度上重构了个人与个人、个人与商家、商家与商家之间的关系，提高了社会经济的运行效率，也增添了社会生活的人文情怀。
目前，分享经济方兴未艾，将在行业细分中不断演进，并带动移动互联网发展进入新阶段。
分享经济的发展正呈现新的趋势。
一是形成新生态。
例如，有的电商通过构建“商品网上批发平台+会员大数据+商品消费+实体经济+产业链金融”的生恋圈模式，形成新零售电商体系，促进商品交易、流逼和消费。
二是拓展新就业空间。
在分享经济浪潮下，各行各业出现了大量的新型就业岗位，未来身兼数职以及从事自由职业的就业者会越来越多。
三是推动实体经济转型升级。
目前，传统的实体经济企业也在围绕自身优势推出分享经济应用，推出一批基于移动互联网的出行类、医疗类手机软件。
四是催生新盈利模式。
除了传统的交易抽成和广告盈利模式，部分平台已经在探索新的盈利空间。
比如，经营出行分享的电商通过打车服务平台开展新车销售等业务。
作为在全球新一轮科技革命和产业变革中涌现的新兴业态，分享经济正加快驱动资产权属、组织形态、就业模式和消费方式的草新。
安徽省合肥市肥东县高级中学2019-2020学年高三3月线上调研考试理综生物试题(解析版)
2020届高三年级3月线上调研理科综合生物试题一、选择题1.同一生物体内，不同组织中的细胞在形态上存在一定的差异，下列关于这些细胞的叙述错误的是A. 通常情况下，这些不同形态的细胞中的核遗传物质是相同的B. 遗传信息的执行情况不同导致了细胞形态的不同C. 每种细胞具有的特定形态与其执行特定功能相适应D. 不同细胞间形态的差异是在细胞分裂完成时产生的【答案】D【解析】【分析】细胞分化指在个体发育中，由一个或一种细胞增殖产生的后代，在形态、结构和功能上发生稳定性差异的过程。
细胞分化是一种持久性的变化，一般来说，分化了的细胞会一直保持分化了的状态，直到死亡。
【详解】除了哺乳动物成熟的红细胞等一些特殊细胞外，同一生物体内不同形态的细胞中，核遗传物质是相同的，A项正确；遗传信息的执行情况不同即基因的选择性表达，基因的选择性表达导致细胞分化，细胞分化使得一个或一种细胞增殖产生的后代在形态、结构和生理功能上发生稳定性差异，B项正确；生物的形态结构是与其功能相适应的，C项正确；细胞分裂只是使细胞数目增加，不同细胞间形态的差异是在细胞分裂后经细胞分化形成，D项错误。
故选D。
【点睛】易错点：细胞分化的实质是基因的选择性表达，同一个体不同体细胞中遗传物质相同，但RNA和蛋白质有所不同。
2.健康人原尿中葡萄糖浓度与血浆中的基本相同，而终尿中几乎不含葡萄糖。
原尿中的葡萄糖是被肾小管上皮细胞主动重吸收的，而葡萄糖由肾小管上皮细胞进入血液不消耗ATP。
下列有关叙述中，不正确的是A. 原尿中的葡萄糖进入肾小管上皮细胞需要消耗ATPB. 肾小管上皮细胞重吸收葡萄糖受细胞膜上葡萄糖载体数量的限制C. 葡萄糖由肾小管上皮细胞进入血液的动力来自葡萄糖的浓度差D. 糖尿病患者的肾小管上皮细胞对葡萄糖的重吸收是顺浓度梯度进行的【答案】D【解析】原尿中的葡萄糖是被肾小管上皮细胞主动重吸收的，据此可知：原尿中的葡萄糖进入肾小管上皮细胞需要消耗ATP，A正确；肾小管上皮细胞对葡萄糖的重吸收是主动运输，受细胞膜上葡萄糖载体数量的限制，B正确；由题意“葡萄糖由肾小管上皮细胞进入血液不消耗ATP”可知，葡萄糖由肾小管上皮细胞进入血液是被动运输，动力来自葡萄糖的浓度差，C正确；糖尿病患者的肾小管上皮细胞对葡萄糖的重吸收是主动运输，是逆浓度梯度进行的，D错误。

2019-2020学年合肥市第一中学高三语文三模试卷及参考答案一、现代文阅读（36分）(一)现代文阅读I(9分)阅读下面的文字，完成各题。
抗战十四年，修改有深意记者日前从教育部获悉：2017年春季教材将全面落实“14年抗战”概念。
教育部表示，教材修改要求将“8年扰战”一律改为“14年抗战”，全面反映日本侵华罪行，强调“九一八事变”后的14年抗战历史是前后贯通的整体，并要求在课程教材中予以系统、准确体现。
教育部要求在中小学地方课程教材中全面落实的“14年扰战”概念，主要是将从1931年“九一八事变”开始至“七七事变”之前东北军民的六年抗战也包含在了“扰日战争”这一历史概念中。
这一修改可以说是对抗战问题认识的巨大进步，也更为符合历史事实。
“九一八事变”不仅标志着日本侵华战争的开始，也标志着中国人民反抗侵略者的开始。
首先，中国抗战第一枪在1931年沈阳北大营就已经打响；第二，由中国共产党领导的东北抗日联军在1931年至1937年之间进行了艰苦卓绝的抵抗，付出了大量牺牲。
在1931年至1937年间，从“九一八事变”开始，中国共产党满洲省委就在积极部署抵抗，9月19日还发表抗日宣言，东北义勇军在共产党领导下壮大成为东北抗日联军，发动广大民众参加抗战。
在此期间，国民党方面也有东北军余部继续进行对日抗战，还有十九路军参加的淞沪抗战也属于其中的一部分。
确立“14年抗战”，无疑有利于全面有效还原我国当年抗日战争的基本历史事实。
有助于消除此前人们在认识上的混乱，同时更是对历史真实的尊重。
14年抗战史能够最大程度地将为争取民族解放而流血牺牲的烈士，囊括到民族英烈的范畴中来，这是对民族脊梁、抗战英灵最重要的告慰和尊重。
8年抗战不能将为民族而战的大量英烈包含在内，特别是由中国共产党领导的东北义勇军、东北抗日联军，他们在最艰苦的环境中流血牺牲，“南有杨靖宇，北有赵尚志”，世界闻名，特别是我们的国歌就是《义勇军进行曲》。
这些不被算作抗战历史，是极大的不公。
2019届安徽省合肥市高三第三次教学质量检测语文试题(解析版)
合肥市2019年高三第三次教学质量检测语文试题（考试时间：150分钟满分：l00分）一、现代文阅读（36分）（一）论述类文本阅读（本题共3小题，9分）阅读下面的文字，完成各题。
在中国制造业发展之初，虽然中国是世界上人口最多的国家，但经济总量在全世界的占比微不足道，落后的社会生产无法满足人们日益增长的物质和文化需要。
在民族复兴、人民富裕的理想和现实巨大的差距面前，强烈的“危机感”很容易催生单纯追求GDP的发展观念，并在全社会范围内取得广泛共识，从而为经济建设树立明确清晰的奋斗目标，凝聚力量，果敢行动。
以“GDP挂帅”为集中体现的发展观念，现在已经不能很好地推动经济的发展了。
十九大报告用“由高速增长阶段转向高质量发展阶段”来概括当前我们经历的历史性转变，“发展”的内涵在这里已然从“富起来”转变为“强起来”，需要关注的不仅仅是经济增长速度，同时还有环境保护、创新能力、科技与文化等很多方面。
“强”是多维度的，需要综合考量，无法把各个维度的“强”通过“加总”成一个“数”，来理解和测度整体的“强”。
新发展观不再能“化简”“还原”成某个单一维度。
在产业发展领域，这种单一维度的观念在更深的层次上，有时表现在关于产业发展进程所谓“一般规律”的认知中。
自蒸汽机发明并广泛应用于生产从而开启了现代工业以来，技术的发展和应用带来了数次被称作“产业革命”的生产大发展。
每一次生产大发展都使社会生产达到了一个之前历史上无法企及的新高度，并且广泛而深远地改变了人们的生活。
在那些关于产业发展的宏观叙事里，这些显而易见的生产力成就被人们与“一般化”“普适化”的道路连接起来了。
这条路上有大的“驿站”，也有小的“台阶”，发达国家一路走来，后发国家的产业发展就是在这条路上“拾级而上”。
这种对产业发展“规律”的“专断论”认知的危险在于，它提供了一把“尺子”，用来“客观”地评判产业体系和企业的“先进”或“落后”，从而给人为的调整和干预提供“进步”的理由和依据。
2019-2020学年合肥市第一中学高三英语三模试卷及答案
2019-2020学年合肥市第一中学高三英语三模试卷及答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AMirroring body language is a way to bond and to build understanding, It is a powerful tool that we use without even knowing it.The most obvious forms of mirroring are yawning and smiling. When you seesomeone yawn, you are likely to yawn immediately. Smiling is also prettycontagious—seeing a smiling person makes you want to smile too.Mirroring body language is a nonverbal way to say “I am like you, I feel the same”. Research shows that people who experience the same feelings are likely to trust, understand and accept each other.Women have the natural ability to pick up and understand body signals. Therefore, it is not surprising that a woman is more likely to mirror another woman than a man is to mirror another man. That's why women are regarded as better talkers, even if they might not really have more close friends.It is interesting that when a man tries to mirror a woman's body language while she is talking, he may seem to her as caring, intelligent and attractive.Mirroring body language is an excellent way to build trust and understanding quickly. If you want to set up a connection with a new person, mirror his or her gestures, sitting position, tone of voice and talking pace. This will make them feel that there is something about you that they like.While mirroring body language gains you acceptance, you still need to take into consideration your relationship with the person you arc mirroring. If you are in a lower social position and are mirroring the body language of your boss, he will view you as arrogant. However, if you want to defeat those who are trying to prove superior to you, mirroring their body language will help defeat them and change their position.1. What does the underlined word “contagious” in paragraph 2 mean?A. Powerful to show one's feelings.B. Affecting each other.C. Attractive to the others.D. Being gentle to people around.2. When copying others, body language, one usually can ______.A. send wrong messagesB. hide true feelingsC. avoid misunderstandingD. win others, acceptance3. What might happen if you try to mirror your boss's body language?A. You will appear very attractive.B. It will help to soften his position.C. You will seem unacceptably proud.D. It willbe a good way to build trust.BOn World Oceans Day, which falls on June 8, the US National Geographic Society announced it would recognize the Southern Ocean in Antarctica, bringing the global total to five.Unlike the Arctic, Atlantic, Indian and PacificOceans—which are defined by the continents that bound them—the Southern Ocean is instead characterized by the Antarctic Circumpolar Current（南极洋流）. According to the National Geographic, the Southern Ocean includes most of the waters surrounding Antarcticaout to 60 degrees south latitude（纬度）."Encircled by the powerfully swift ACC, it is the only ocean to touch three others and to completely embrace a continent rather than being embraced by them," Sylvia Earle, a marine biologist and oceanographer, told the Daily Mail.Those familiar with the Southern Ocean know it's unlike any other. "Anyone who has been there will struggle to explain what's so charming about it, but they'll all agree that the glaciers are bluer, the air colder, the mountains more awful and the landscapes morecaptivatingthan anywhere else you can go," Seth Sykora-Bodie, a marine scientist at the National Oceanic and Atmospheric Administration, told National Geographic.National Geographic hopes their revised maps will bring public awareness to the region, thereby encouraging Southern Ocean conservation—but its significance is beyond that."We think it's really important from an educational standpoint, as well as from a map-labeling standpoint, to bring attention to the Southern Ocean as a fifth ocean," Alex Tait, National Geographic Society geographer, told The Post. "So when students learn about parts of the ocean world, they learn it's an interconnected ocean, and they learn there are these regions called oceans that are really important, and there's a distinct one in the icy waters around Antarctica."4. Why is the Southern Ocean different from other oceans?A. It has never been explored before.B. It surrounds the Antarctic all around.C. It is enclosed by the fast-flowing ACC.D. It has ecologically distinct environment.5. What does the underlined word "captivating" in paragraph 4 probably mean?A. Strange.B. Unusual.C. Attractive.D. Informal.6. What does the National Geographic think of the Southern Ocean?A. It will be instructive for students.B. It will promote tourism development.C. It will encourage public to treasure water.D. It will draw scientists to study in the Antarctic.7. What is the best title for the text?A. World Oceans DayB. Revised Antarctic MapsC. Adding a New OceanD. New Discovery under the SeaCPaper is an important part of modern life. People use it in school, at work, to make artwork and books, to wrap presents and much more. Trees are the most common material for paper these days.So how do people make paper out of trees today? People first cut trees, load them onto trucks and bring them to a factory. Machines cut open the outer coverings of the trees, and cut the trees into pieces. Those pieces are boiled into a soup. After that, it is hit flat, dried and cut up into sheets of paper.The entire process, from planting a small tree to buying your school notebook, takes a very long time. Just growing the trees takes 10 to 20 years.Making tons of paper from trees can harm the planet. Humans cut down 80, 000 to 160,000 trees around the world every day, and use many of them to make paper. Some of those trees come from tree farms. But people also cut down forests for paper, which means that animals and birds lose their homes.Cutting forests down also contributes to climate change, and paper factories pollute the air. After you throw paper, it often takes the paper six to nine years to break down. That's why recycling is important. It saves a lot of trees, slows climate change and helps protect endangered animals, birds and all creatures that rely on forests for their homes and food.So if paper isn't good for the environment, why don't people write on something else?The answer: They do. With computers, tablets and cellphones, people use much less paper than in the past. Maybe a day will come when we won't use paper at all — or will save it for very special books and artworks.8. What can we know about making paper out of trees?A. It costs much money.B. It takes a lot of time.C. It is very easy and fast.D. It is dangerous and difficult.9. What is the impact of paper production?A. It promotes the recycling.B. It does harm to the environment.C. It slows down the climate change.D. It protects the animals from losing homes.10. How will we use paper someday in the future according to the text?A. Use it for books only.B. Use the recycled paper.C. Treasure it occasionally.D. Use it for artworks.11. What idea does the author want to express from the text?A. The influence of making paper on environment.B. The wonderful experience of making paper.C. The necessary process of making paper.D. The good reasons for making paper.DDid you know people who live in different parts ofChinahave different habits and preferences? For example, people from southernChinaprefer to eat vegetables, while people from northChinalike to eat meat. According to a new study in a journal, gene variations (变异) might be responsible for these differences. Researchers fromChina’s BGI collected genetic information from 141,431 Chinese women, who came from 31 provinces and consisted of 36 ethnic minority groups.They found that natural selection has played an important role in the ways that people living in different regions of China have developed, affecting their food preferences, immunities (免疫力) to illness and physical features.A variation of the gene FADS2 is more commonly found in northern people. It helps people metabolize (新陈代谢) fatty acids, which suggests a diet that is rich in flesh. This is due to climate differences.Northern Chinais at a higher latitude. This weather is difficult to grow vegetables in. Therefore, northerners tend to eat more meat.The study also found differences in the immune systems of both groups. Most people in southernChinacarry the gene CR1, which protects against malaria. Malaria was once quite common in southernChina. In order to survive, the genes of people in the south evolved to fight against this disease. However, people in the south are also more sensitive to certain illnesses, as they lack the genes to stop them.Genes can also cause physical differences between northerners and southerners. Most northerners have theABCC11 gene, which causes dry earwax, less body smell and fewer sweats. These physical differences are also more beneficial to living in cold environments. Southerners are less likely to have this gene, as it did not develop in their population.12. What did the new study focus on?A. Regions.B. Eating habits.C. Gene variations.D. Ethnic minority groups.13. What is the main function of the gene FADS2?A. It helps store fat.B. It helps digest meat.C. It helps gain weight.D. It helps treat an illness.14. According to the study, most northerners ________.A. sweat less frequentlyB. are immune to malariaC. prefer vegetables to meatD. are more sensitive to climates15. How many differences did the study find related to genes?A. Two.B. Three.C. Four.D. Five.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

俗话说“赠人玫瑰，手留余香”，乐于助人就是这样一种既能帮助别人，又能收获满足的事情。
然而，（ ），这是怎么回事？从心理学的角度来说，这种现象被称为“同理心耗竭”。
“同理心”就是站在他人的角度和立场上，理解他人的内心感受。
同理心较强者能够从他人的表情、语言等方面判断其情绪，进而可以 地感受和体谅别人，并以此作为行事依据。
然而，同理心也是有限度的，而且能够被消耗。
只要使用同理心，就会导致同理心耗竭，进而危害身心，比如引发睡眠问题等。
那么，对于同理心较强者来说，如何避免自己的同理心消耗过大呢？一是把同理心变成“同情心”。
同理心较强者在帮助别人时，往往 地将自己代入别人的情境中，而过度介入别人的痛苦和烦恼，就会造成同理心消耗过大，此时不妨化同理心为同情心。
二是找到同理心的边界。
没有人的同理心是取之不尽、用之不竭的，因此，要找到自己同理心的边界，既不要 ，也不要过分介入，而要明确自己的责任范围，比如在帮助别人的时候，可以提出建议，也可以给予支持和陪伴，但不能过于干涉别人的选择，更不应 ，代替别人痛苦和烦恼。
1．下列在文中括号内补写的语句，最恰当的一项是( ) A ．有些人被别人的情绪带着走，导致身心俱疲，结果没有获得快乐 B ．有些人并没有获得快乐，而是身心俱疲，结果被别人的情绪带着走试卷第2页，总11页C ．有些人被别人的情绪带着走，非但没有获得快乐，反而导致身心俱疲D ．有些人非但没有获得快乐，反而被别人的情绪带着走，结果导致身心俱疲 2．依次填入文中横线上的成语，全都恰当的一项是（ ） A ．设身处地 不由自主 冷若冰霜 包办代替 B ．设身处地 情不自禁 拒人千里 越俎代庖 C ．身临其境 情不自禁 冷若冰霜 越俎代庖 D ．身临其境 不由自主 拒人千里 包办代替 3．文中画横线的句子有语病，下列修改最恰当的一项是（ ）A ．过度使用同理心，就会导致同理心耗竭，进而危害身心，比如引发睡眠问题等。
B ．如果使用同理心，就会导致同理心耗竭，进而危害身心健康，比如引发睡眠问题等。
C ．如果过度地使用同理心，就会导致同理心耗竭，进而危害身心健康，比如引发睡眠问题等。
D ．只要不过度使用同理心，就可避免同理心耗竭，进而防止危害身心，比如引发睡眠问题等。

对于任何一个曾沐浴过先锋文学的余泽而有志于小说创作的新手作者而言，对故事的戒备恐怕已经成为一种先在的常识，所谓“小说在故事终止处开始”的说法就是这种戒备意识的集中显现。
事实上，就中国本土先锋文学思潮嬗变的轨迹来看，“故事”其实并未远离，1990年代以后更是全面回潮，但是当“写什么”又一次代替“怎么写”去接管小说时，那个时刻被后来的很多文学史家和批评家描述为一个先锋文学精神终结的时刻，似乎在意味着更具现代性和探索意识的先锋文学理解中，传统的故事既已被打倒、拆解或置换，就再也不可能构成驱策文学向前的资源。
这一理解导致了两个至今仍有相当影响的结果——其一，以故事驱动的小说在艺术性上要弱于以叙事驱动的小说成了被广泛认可甚至是具有自明意义的写作观念；其二，除了像莫言这样的庞然大者，即便一个小说家擅于写故事，他也绝少以此自矜，似乎讲好故事并非荣耀——并最终形成了我们开头说到的那个认识效应。
然而，最近几年事情却有了变化。
先是2015年，赵松的《抚顺故事集》出版，在读书圈引起不小的关注；同年，以故事命名的小说集还有颜歌的《平乐镇伤心故事集》和宝树的《时间狂想故事集》；随后两年，以“故事集”为名的各类纯文学作品越出越多；此外，还有为数不少虽不直接以故事为名，但一看便摆明了要讲故事的小说集，如朱岳的《说部之乱》、冯唐的《搜神记》、刘汀的《中国奇谭》、赵志明的《中国怪谈》，以及化身“说书人”身份的张大春的《春灯公子》等。
当然，仅以“故事”来命名作品可能说明不了太多，放眼世界，诸如《尼克•亚当斯故事集》《九故事》《东方故事集》之类的名号也所在多有。
但是这一回，中国故事的复归并不羞涩，不但大张旗鼓地亮出本尊的旗号，而且值得注意的是，从张大春、李敬泽到弋舟、冯唐再到赵志明、郑在欢，这些故事的讲述者不但囊括了50后到90后的完整代际，还各自有着文坛宿将或新锐的名号，在文学圈子里代表着有相当影响的文学品位，他们不约而同，重建小说与情节的友善关系，重塑对故事的敬畏和尊重，这恐怕不能简单地以巧合来解释，虽然还不完全明朗，但至少意味着新世纪关于小说理解的又一次深刻转向：故事，真的重新开始了。
写作《故事》的罗伯特•麦基说：“故事并不是对现实的逃避，而是一种载体，承载着我们去追寻现实，尽最大的努力挖掘出混乱人生的真谛。
”如果说以现代主义为代表的小说之所以要放逐故事是出于对陈旧叙事成规的不满，因为是故事使小说获得情节秩序的支撑，要变革这个文体秩序，就必须从破除故事入手。
但在经历了现代主义和后现代主义种种“后设”叙事的实践之后，小说再度召唤故事时，对故事的理解当然也势必经历一个螺旋式的上升，或者说，小说家有了一套新的讲述故事的方法，既能保持故事应有的情节密度、弹性和内爆力，又能突破单一线性封闭叙述的老套，使小说的文体属性更鲜明，也更开放。
因此，对于故事的再度开始，我们且谨慎地乐见其成。
（摘编自马兵《故事，重新开始了》，《南方文坛》2018年第4期）4．下列关于原文内容的理解和分析，正确的一项是（）A．先锋文学作家关注的是“话语”，对于“故事”，他们有一种集体无意识的防备心理。
B．中国本土先锋文学并不成功，当“写什么”再次代替“怎么写”之时，它就结束了。
C．“故事”并未远离，尤其最近几年，无论是创作还是影响，都让人觉得眼前一亮。
D．破除故事并非现代主义和后现代主义的本意，它因此建立了一套讲故事的新方法。
5．下列对原文论证的相关分析，不正确的一项是（）A．先锋文学对故事的戒备是本文论述的逻辑起点，文章由此又对其影响进行了分析。
试卷第4页，总11页B ．文章运用了对比论证的方法，以突出先锋文学对故事采取否定的态度是不可取的。
C ．从现象到亮出旗号再到创作队伍的组成，文章对“故事，重新开始了”的论证严密。
D ．文章在论述故事重新开始了之后，进一步分析了讲故事的变化，其论证层次清晰。
6．根据原文内容，下列说法不正确的一项是（ ）A ．先锋文学时代，莫言的创作仍坚持以讲好故事为荣，这为他赢得了诺贝尔文学奖。
B ．中国的先锋文学思潮，既影响了人们对小说艺术的评价，也影响了作家的创作观。
C ．《西游记》和《红楼梦》这些古典作品承载着人们对现实的追寻和人生真谛的挖掘。
D ．近年出现的以故事命名的小说，虽然也讲故事，但讲故事的方法已与过去有所不同。
（题文）阅读下面的文字，完成下列小题。
渐渐 朱以撒空无一叶的九重葛，整个冬日在寒风中抖瑟。
近日发现有星点紫红色的叶芽从枝条的骨节探出，每一日都非常微弱地发展。
与此同时，朋友赠送的洋兰，细细地看，正在敛约着极盛时刻的嫣红，细微地走向它的反面。
这两种走向，因为太细了，往往让人浑然无觉。
正常的生长或者凋零，都是在难以分辨中进行的。
在叙述这种进展程度时，我经常运用两个字——渐渐。
一滴融入了清水的墨，坠落在白色宣纸上会有多大，效果如何，一般人是难以言说的。
有的人挥毫时左手总是攥着一团卫生纸，墨一入纸，便飞蛾扑火般地敷上去，吸干。
于是右手不断地写，左手不断地吸，一眼可见手头功夫的匮乏。
同时，左手这个寒酸的动作与优雅的右手难以匹配。
我习惯了墨汁垂落，宣纸柔软承露般地接住它的圆润，然后缓缓化开。
其向着外围扩散的模样毛茸茸的，内浓外淡，内黑外白，非人工可以合成。
搁笔后挂起，品一盅茶后再去看看，晕化恰到好处，比挥毫时刻多了一些水乡气息。
因为渐渐，才如此微妙。
深沉的夜色里，宁静中传来更夫的脚步声，还有低沉的梆声。
好像时间是由更夫带来的，由他来向梦中人传达时间的进度。
在一个缺乏钟表的年份，更夫出现，在深夜里，替人守时，使梆声飘入睡意里。
夜，在渐渐中流转。
那些赶早的人满怀感激，起身收拾行囊，穿过夜幕渐淡阗寂的街巷，悄悄地消失在远处。
不少旧日的文本都展示了这个情节，甚至由更夫把夜间许多叙事的残片缝缀起来，让深沉的夜晚有一些动感——在更夫的步履下，舒缓的、浸润的青石板路面上，共同地流露出连绵的湿意。
一位小姐倚在临街窗旁，右手执一柄描花纨扇，正朝窗外张望。
街面上耍把戏的正在调遣三寸不烂之舌，寻常话语一经渲染，灿若桃花。
小姐渐渐笑了，很平和。
她把手抬起来，让纨扇更近于自己的脸庞，一旦笑颜大展，纨扇已经遮掩了春色。
春色三分毋须多，泛滥起来就不那么可爱了。
像一夜秋风凌厉，打落万千叶片，这与我偏重于渐渐的心理相违。
有的黄叶就能生出一些美感。
它是先落下两片，再落下两片。
一点点地递进，含蓄文雅，有一种长调般的韵味。
让人端详着树顶，晚秋正在缓步移近，天空在落叶的疏朗中渐大，这个秋天才算是一步一步被拥有了。
孩子渐渐地长大了，长辈渐渐地老去，每个人都朝着自己相反的方向进展，由小到大，由壮而衰。
老子是不看好强壮的，物壮则老，他说。
在他眼里，人最好不要长大，永远地柔、弱，这样就有无限生机。
生活慢下来时，孩童说着稚气无忌的话语，无知以至无畏。
疏离了天性，超常地精明有心计，善于察言观色，在我眼里，这样的孩童就让人讨嫌了。
我读到几幅儿童书法，笔下老到，甚至老气横秋，心里就十分惋惜。
在这个变数很大的空间里，没有多少人乐意那么长久地等待。
一粒花蕾，不要急于让它成为一朵花。
生活的节奏在看不见的地方支配着我们的手脚呢。
主人从草地上觅食的鸡群里挑了一只芦花色的公鸡，作为款待客人的佐食佳肴。
从炖罐里飘出来的肉香，让人贯串起放纵奔跑于田畴地角、花径草丛中正常生长的过程。
从出壳到长成，完全是自然而然的积累，允许生长的缓慢。
主人安时处顺的生存观，显然有过人的耐心。
我们在口舌感到快感的同时，还有一种美感，渐渐递增起来的美感。
像自然草木那样，渐渐地生，渐渐地长，渐渐地枯黄；像自然四季那样渐渐地来，渐渐地渗透，渐渐地转换。
我们的日子，真要原生态一些，还真得倚仗渐渐了。
（有删改）7．（小题1）下列对文本相关内容和艺术特色的分析鉴赏，不正确的一项是（）A．文章从九重葛与洋兰让人浑然无觉的两种截然不同生长走向写起，显示出作者是个生活的有心人，也引发了下文关于渐渐的思考。
B．本文思路开阔，今古相接，由物及人，形散神聚，具体形象地表达了作者对“渐渐”的感悟与思考。
