Six months before she died,my grandmother moved into an old people’s home and I visited her there when I was in Britain.She was sitting in the living room with about15other residents,mostly
women,half of them asleep.The room was clean and warm,with flowers and pictures,and the care assistants were kind and cheerful.“The Weakest Link”was on TV(“to keep their brains active”one of the assistants said,)and the only other sound was snoring and embarrassing digestive noises.It was depressing.Gran talked a lot about how much she missed seeing her grandchildren(my nieces aged7and5),but I knew from my sister that they hated going to visit her there,and to be frank,I couldn’t wait to get away myself.
So I was interested to read a newspaper article about a new concept in old people’s homes in France.The idea is simple but revolutionary,combining a residential home for the elderly with a nursery school in the same building.The children and the residents eat lunch together and share activities such as music,painting,gardening,and caring for the pets,which the residents are encouraged to keep.In the afternoons,the residents enjoy reading or telling stories to the children, and if a child is feeling sad or tired,there is always a hug and a kind of lap to sit on.
The advantages are great for everyone concerned.The children are happy because they get a lot more individual attention,and respond well because someone has time for them.The residents are happy because they feel useful and needed.They are more active and more interested in life when the children are around and they take more interest in their appearances too.And the staff are happy because they see an improvement in the physical and psychological health of the residents and have an army of assistants to help with the children.
Nowadays there is less and less contact between the old and the young.There are many reasons for this,including the breakdown of the extended family,working parents with no time to care for ageing relations,families that have moved away,and smaller flats with no room for grandparents. But the result is the same increasing numbers of children without grandparents and old people who have no contact with children.And more and more old people are lonely and feel useless,along with more and more families with young children who desperately need more support.It’s a major problem in many societies.
24.What was wrong with the home that the writer’s grandmother was in?
A.The old weren’t looked after properly.
B.Children weren’t allowed to visit.
C.The old were not getting along well.
D.The residents were not made active.
25.What was the new concept that the writer read about in the newspaper?
A.Old people being allowed to keep pets.
B.A nursery school inside an old people’s home.
C.Children visiting old people for lunch and birthdays.
D.Old people staying at home with their grandchildren.
26._________are more active and more interested in life at this new type of old people’s home.
A.The staff
B.The seniors
C.The parents
D.The children
27.What does the author think is a major problem in society at present?
A.There is not much contact between the old and the young.
B.The breakdown of the extended family.
C.Seniors are lonely and unhappy.
D.The families keep moving around.

While most consumers wish to reduce plastic waste,it’s not an easy goal to achieve.That’s because the cheap and long-lived material is found in almost every daily necessities.Now,an Indonesian-based company has come up with a delicious solution.
David Christian,the cofounder of Evoware,says after investigating various materials,the company settled on seaweed.Unlike corn,commonly used for containers,seaweed does not require water,fertilizers,or large amounts of space.According to Evoware,as much as40tons of seaweed can be grown in an area the size of a baseball field.Since Indonesian farmers harvest more seaweed than they can sell,it’s easy to find the material.
The seaweed packaging is safe to consume and can entirely dissolve(溶解)in hot water.While other eatable wrappers(包装纸)may not have any taste,Dubbed Ello Jello,the singl e-use cups invented by Evoware,are available in four tastes—orange,lychee,peppermint,and greentea.The best part?You can order the powder and make them at home!Though currently they cannot stand hot liquids,Evoware is working on making heat-resistant cups as well.
While the seaweed products seem like a perfect replacement,it’s a hard-sell in Indonesia. According to Christian,“The awareness and sense of urgency to minimize the use of single-use plastic is still very low.This makes our bioplastic seem unnecessary.”Also a factor is the cost, which is higher than using plastic.However,Evoware believes they can reduce the price once the company moves to mass production.Hopefully,Evoware will succeed in convincing people worldwide that switching to their products will go a long way in protecting our beautiful planet.
28.How does seaweed differ from corn?
A.It sells better.
B.It’s less expensive.
C.It takes less labor to process.
D.It needs less resources to grow.
29.What character do seaweed wrappers have?
A.They melt in cold water.
B.They are easy to break down.
C.They can be made at home.
D.They come in your favorite tastes.
30.What does the underlined word“they”in Paragraph3refer to?
A.Plastic containers.
B.Evoware’s current cups.
C.Heat-resistant cups.
D.Eatable packaging.
31.What can we infer from Christian’s words in the last paragraph?
A.The price of plastics will go down.
B.Indonesians care little about the planet.
C.It takes much effort to promote the new product.
D.The seaweed products need much improvement.
D
In a study published in Frontiers in Psychology,European neuroscientists(神经系统科学家) determines that our fears of snakes and spiders are inborn,even babies become alarmed at the sight of them.How did they figure it out?Well,they“scared”some babies for science!
Though not everyone is frightened of snakes and spiders,studies have shown more than a third of the child population and adult population have a strong dislike of them,and they’re the most reported specific fear sources.Even though poisonous spiders and snakes aren’t a huge problem for most of us now,they’re still“ancestral threats”our primate ancestors had to deal with for millions of years.
Scientists have already shown these fears are deep-seated to most people,but they are usually in
adults or adolescents,so it is possible they’ve learned such fears from their environments.To really prove whether or not human brains are automatically wired to dislike snakes and spiders,the experiments had to test people with almost no environmental influence:babies.
For this study,the neuroscientists showed16six-month-olds pictures of snakes and fish,and spiders and flowers.The idea was to match the scary animals with visually similar non-threats,to make sure it was really the snakes or spiders the babies would react to.And they did react,as eye-tracking software made clear:their pupils(瞳孔)were noticeably bigger when looking at the spiders and snakes,which corresponded to a much greater stress reaction.
But it’s a success,since the results do suggest we have an inborn developed system in our brains that is specifically adapted to noticing,and not much caring for,snakes and spiders.
So as you’re deciding on the decorations for Halloween,and trying not to scare your friends too much,keep in mind just how deep some fears go.And,if you have a baby you don’t mind scaring just a little bit,the right decoration could be the perfect chance for some DIY neuroscience!
32.Why did the European neuroscientists choose babies to carry out the experiment?
A.To prove the environment has no influence on our fears of snakes and spider.
B.To show that their brains are different from those of the adults.
C.To make it easy to control the environments of the babies.
D.To show most fears are learned from babies.
33.In the experiment,the scientists tested the babies by_________.
A.making them look at the model snakes and spiders
B.monitoring their eyes’reactions to the pictures
C.stressing the babies with some software
D.making comparisons between different babies’pupils
34.We can learn from the text that_________.
A.approximately one third of people dislike spiders and snakes
B.poisonous spiders and snakes have caused many problems
C.adults have learned their fears from their experiences
D.the experiment results indicate we fear spiders and snakes by nature
35.What does the author suggest in the last paragraph?
A.Frightening decorations for Halloween should not go too far.
B.Snakes and spiders should be used for Halloween decorations.
C.The babies should not be scared on earth on Halloween.
D.It is better to turn to neuroscientists to decorate Halloween.

D ．9440x y -+= 【答案】B 【解析】利用导数求出曲线2y x =的切线的斜率的取值范围，然后利用导数的几 何意义判断各选项中的直线是否为曲线2y x =的切线，由此可得出结论. 【详解】 对于函数2y x = ，定义域为[)0,+∞，则22 y '= +>， 所以，曲线2y x = 的切线l 的斜率的取值范围是()2,+∞. 对于A 选项，直线5210x y -+=的斜率为5 2 ，令522y '=+=，解得1x =，此 时3y =， 点()1,3在直线5210x y -+=上，则直线5210x y -+=与曲线2y x =相切； 对于B 选项，直线4210x y -+=的斜率为2，该直线不是曲线2y x =的切线； 对于C 选项，直线13690x y -+=的斜率为 13 26 >， 令13 2 6 y '= += ，解得9x =，此时21y =， 点()9,21在直线13690x y -+=上，所以，直线13690x y -+=与曲线2y x =相切； 对于D 选项，直线9440x y -+=的斜率为 9 24 >， 令9 2 4 y '= = ，解得4x =，此时10y =， 点()4,10在直线9440x y -+=上，所以，直线9440x y -+=与曲线2y x =相 切. 故选：B. 【点睛】 本题考查利用导数的几何意义验证函数的切线方程，考查计算能力，属于中等题. 4．中国传统扇文化有着极其深厚的底蕴．一般情况下，折扇可看作是从一个圆面中剪
高考复习：高三生如何准备月考模拟考
高考复习：高三生如何准备月考模拟考 未 2014-01-10 0832 高考复习：高三生如何准备月考模拟考 高三的日子，黑板上距高考倒计时的数字被放大了无数倍，生活由语数外理化生拼凑而成，铺天盖地的考试是一年的主旋律。高三的月考，尽管你心里清楚这只是高考的练兵，但走进考场，依然忐忑，依然期待通过考试来验证自己的进步。那么，充分的考前准备就是你胜利的第一重保障，我们一起来想一想，月考之前要准备些什么。 知己知彼百战不殆 《兵法》有云：“知己知彼，百战不殆。”了解月考的考试内容和考试目的是第一步。高三的四次月考，会各有侧重。首先，考试内容会配合复习进度，考查阶段学习重点和难点，其次，四次考试会以变换题型的方式对高考进行“围追堵截”，真正实现高考前预备战的补漏作用。另外，月考的难度系数可能会略高于高考，这样才能起到“带着沙包奔跑”的加码作用。 这样，我们在考前复习时，就应针对以上的内容进行。不管现在复习的内容在高考所占比例有多少，都以阶段学习为界，寻找重点，提前加强训练。前两次月考已经考过的题型可以减少训练，贴近高考却一直没有考查过的题型作为复习重点。中等难度，甚至高难度的习题应该集中练习，以避免出现考试当中措手不及的惶惶然。复习中也不要采取“题海战术”，题要做，但要有针对性地做，明确考试对象，主攻考试重点，能让你有限的复习时间“事半功倍”。在三中，一些善于思考，对高考有计划、有全局准备的同学，甚至可以推断出下次考试的某些题型和考查内容。有的放矢，才能射中靶心。 有些同学不太愿意为了月考放弃自己的高考长期计划，觉得月考没有那么重要，这种全局式的复习值得提倡，但，我要提醒你，如果你从来没有在任何一次考试中找到全力出击的感觉，到了高考，也许就失去了临场战斗力！月考给你带来的益处并不仅仅是每次考查的知识点，更重要的是你能对每场考试全力以赴的准备，超越自我的发挥。 临阵磨枪不快也光 “临时抱佛脚”是学生在学习生涯中很难避免的尴尬局面，所以“不快也光”成了我们挂在嘴边的自我安慰。其实，有时候临阵磨好了枪，还能打个胜仗呢！时间短，任务重，怎么磨才够光呢？ 最接近考试状态的就是计时做套题，这是最能模仿考试状态的做法。在做题过程中，注意合理分配做题时间，核对答案后，及时弥补自己知识上的漏

重庆市第122中学是一所教学质量优秀的城郊普通初中
重庆市第122中学是一所教学质量优秀的城郊普通初中，是国家级首批基础教育课程改革实验学校，从2001年至今，已走过7年的课改历程。我校有一大批青年教师在课改中不断摔打磨练，并迅速成长起来。新课程改革的根本出发点是为了一切学生，而改革的主要落脚点是在课堂。课堂是教师发展、学生成长的主阵地，更是提高学校教学质量的核心所在，甚至有的专家们提出了“改革最终发生在课堂上”的观点。回顾7年走过的路程，我们深刻地意识到，只有带着反思上路，不断加强课堂教学改革，才能真正落实课改理念。 冷静反思，发现问题 2001年，我校成为全国首批基础教育课程改革实验学校。新的课改理念让教师们激情澎湃，兴奋不已，以饱满的热情投入到课改工作之中，将课改理念转化为具体的教学行为。在课改初期，教师对课改理念吃得不透，对新课改理念的认识存在不足，这使我们很快意识到：我们的课堂还没有真正体现课改理念，对课改理念的认识还存在一定的偏差。为此，我们很快从浮躁与狂热中沉静下来，开始深刻反思：我们的课堂教学是否真正体现了课改理念？课堂教学究竟存在哪些问题？我们应如何立足课堂，彰显课堂魅力？从而让教师的专业素养不断变得深厚，让学生的后续学习能力得到更大的发展，让学校的办学水平更上一层楼。 为了找出问题，我们一头扎进课堂，深入调研。通过调研，我们发现：我们的课堂教学中尚存在诸多问题，有的甚至是严重的问题。 问题1．舍本逐末，过分追求课堂形式 (1) 满堂问取代满堂灌。 追问：提出的问题是否有价值？提得合适吗？有没有梯度和系统？是否有思维含量？ （2）课件+表演+讨论=自主合作学习 个别教师片面理解“自主、探究与合作学习”，一节课大部分的时间都用来进行漫无边际的讨论或安排学生表演。讨论中，课堂上常常有三分之一的学生“混于其中，乐得清闲”，他们多半是在谈论与课堂无关的话题；表演时，课堂上绝大多数学生是表演者的“忠实“观众，思维未参与其中；课件展示，画面美轮美奂，学生一晃而过，心中未留下多少痕迹。这些教学，导致课堂上该凸显的教学重点未凸显出来，改突破的教学难点并未得到突破，学生该过手的知识并未过手。这样的课堂缺乏实质性的师生互动、生生互动、生本互动；缺乏有价值的知识的生成。并未充分发挥出自主、合作、探究学习方式的作用。 这类课程不但大大降低了课堂教学效率，而且还助长了学生对问题不作深入探究、不愿仔细倾听的恶习。长此下去，势必形成学生在学习上浅尝辄止的浮躁个性。这样的课堂培养出来的学生虽然有勇于表现，口头表达能力强的优点，却缺乏扎实钻研，专注于问题独立思考的良好品质。 追问：单纯的课堂热闹就是自主合作探究学习吗？内容与形式，孰轻孰重？该如何真正让学生的思维动起来？ （3）课堂评价缺乏原则，巴掌赞歌满堂飞。 有的教师在课堂上对学生的评价缺乏原则，一味叫好。答得好的，究竟好在哪里并未指出；答得不好的，怕挫伤学生积极性，不予置评，误导学生。 追问：评价应遵循的原则是什么？改如何正确引导学生？ 问题2．照“案”宣科，课堂缺乏动态调整 有的课堂教学只是在执行既定教案，缺乏对教案自觉的动态调整。教师对学生的认知准备了解不充分；教学目标的设定成为教案完整的一种形式。教师想教什么与实际在教什么存在一定的脱节。 追问：教师想教什么？教师实际又在教什么？学生实际学到了什么？ 问题3．缺乏专业引领的机制。 专家与教研员很少，一线教师很多，深入课堂，观察指导，与教师平等对话与交流。教师对

2020.2021河北衡水高三语文一模模拟第一次月考解析版
2020（2021）年高三第一次模拟考试语文试题 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1～3题。 《大学》以“明德”作为思想的聚焦，开篇即言“大学之道，在明明德，在亲民，在止于至善”，指出大学的宗旨在于明“明德”。历代的学者对“明德”概念做出不同的解释，东汉儒者郑玄释为“至德”，唐代经学家孔颖达释为“光明之德”，清人唐文治释为“君德”。这些阐释看似不一，但是都反映出“明德”与先王政教之间1A有一定的渊源关系。结合“明德”思想的历史发展轨迹和《大学》文本来看，《大学》中的“明德”思想实际包含了两个层面的内容。1B 其一，“明德”指理性的政治美德，“明明德”就是要彰明、弘扬这种美德。从《大学》中的阐发来看，从政之人要心怀仁爱百姓之心，始终保持谦虚谨慎的态度；君主和百官应以义制利，不以个人私欲损害百姓的利益和福祉；君主百官要做到内心公平中正，一言一行为百姓起到示范作用。《大学》中将“明德”指向“明政之德”，是对早期“明德”传统的继承。“明德”最早出现在金文中，指承自先祖、以威仪和勤政为主要特征的政治品格。在《国语》《左传》《康诰》等早期文献中，“明德”也多次出现，用以颂扬古代圣王的美好德行 3B。在这些文献中，“明德”常与“幽昏””无礼”等词对举而出现，凸显出“明德”是辟邪、淫佚、荒怠、粗秽、暴虐等非理性的政治品性的对立面。 其二，“明德”也指人人本有、自身所具的光明德性。“明明德”就是通过教育和自明，使人所本有的光明德性得以显明。《大学》对早期的“明德”乃“明政之德”的传统进行了继承，但同时对“明德”的主体和“明德”之“德”的内容进行了扩充。在西周及更早的时期都是推行王官之学，早期的“明德”具有着鲜明的贵族性，但是在《大学》中，“德”不再被认为是君主、官员、贵族所独享，而是属于所有人。对“明德”的主体进行扩充，一方面体现出人文秩序的构建、
