If the word researcher brings to mind someone who works in a laboratory doing experiments or reads a11 day in a librar y,then meet Dr.Sylvia Earle.Dr.Earle has carried out much of her research deep under the sea.Her outstanding work at sea ha s included leading around 70 expeditions(探索)and spending over 6,500 hours under the water. She also holds the world record for the deepest walk alone on the ocean floor at a depth of 381 metres.It’s no wonder she ha s been given the nickname“Her Deepness”.

As a child,Dr.Earle was always interested in wildlife and was never afraid to find out about nature.Her parents told her to touch animals and insects,and not to be afraid of them.When she was older,she was given the opportunity to develop this int erest thanks to scho1arships to study botany at university.She also took courses in sea diving and decided to devote herself t o marine(海洋的)biology.It was this decision and her determined character that led her to have a truly remarkable career.

After several years of diving,Dr.Earle took part in a research expedition in an underwater laboratory.The laboratory was called a Tektite Habitat and it allowed divers to remain under the water to carry out research for weeks at a time.In 1970 an all-female group went on the sixth expedition of the Tektite II scientists-in-the-water programme.Dr.Earle was asked to lead the expedition.Along with another four women-three scientists and an engineer-she stayed in the Tektite Habitat for two wee ks.

Marine life has always been at the centre of Dr.Earle’s work and she is highly respected for her authority in this field.She i s often asked to give talks by environmental groups about marine life as well as her plan to create a global network of marin e protected areas. What makes her extra special is that she doesn’t look upon her work as a job,but as her vocation(天职)in life.

A paperclip,made of steel wire bent into a looped()shape,is an instrument used to hold sheets of paper toget her.This common device is a wonder of simplicity and function.But where did this simple,cheap,and practical invention co me from?

In the late 19th century,the most common way to hold papers together was by using a pin.Although the pin was an ine xpensive tool and was easily removable,it would 1eave holes in the https://www.sodocs.net/doc/074059889.html,ter,as steelvwire became more common,invent ors began to notice its elastic()feature.With this feature,it could be stretched and twisted into various clip-like objects.In the years just before 1900,quite a few paperclip designs appeared.The name most frequently associated with the paperclip invention is Johan Vaaler,a Norwegian inventor.However,Vaaler’s clips were not the same as the paperclips curr ently

in use.Specifically,they did not have the inside loop we see today.The familiar looped design was invented by Gem Manuf acturing Ltd.in England.This clip is therefore sometimes known as the Gem clip.

Because of Vaaler,the paperclip played an important historical role in Norway.During World War II,Norway was occu pied by the Nazis.Norwegians were prohibited from wearing any symbol of their national unity(),such as buttons wi th the initials of their king.Thus,in protest,they started wearing paperclips to show their unity.The reason for doing this was simple:Paperclips were a Norwegian invention whose original function was to bind together.After the war,a giant papercli p statue was put up in Oslo to honour Vaaler—even though his design was never actually produced.

25.According to the first paragraphthe paperclip is________.

A.made of paper

B.for holding clothes together

C.shaped like a pin

D.inexpensive and useful

26.One way the paperclip is better than the pin is that_________

A.it is cheaper

B.it is simpler

C.it doesn’t damage the paper

D.it can be removed more easily

27.Which of the following best shows what the Gem clip looks like?

28.The last paragraph is mainly about_________.

A.how widely used Vaaler’s clip is

B.how V aalers clip became a national symbol

C.how the Nazis ruled the Norwegian people

D.why Norwegians had the initials of their king on their buttons

C

I was born on the last day of February.I’ve always felt sorry for February,squeezed between the big months of January( named for the Roman god Janus,keeper of gateways)and March(after Mars,the god of war).

The first Roman calendar,it is said,had 10 months and no February.Beginning at the vernal equinox()with March,i t ended with December.In an agricultural society,winter was of little importance,and thus went undivided.

January and February were added about 700 B.C.by the second king of Rome,Numa Pompilius.He made all the months 29 or 31 days,but shortened February,the last month of the year,by giving it only 28.

Next,it was the church’s turn.In 1582 Pope Gregory XIII announced a new calendar in Europe.Many changes were ma de,but the Pope passed up yet another chance to give February equality with the other months.

It’s messy,even dangerous,changing how we measure time,but Pope Gregory was hardly the last one to try.The League o f Nations received over 150 new calendar designs,and the United Nations has considered more proposals since.Each propos al involves something that supposedly modernizes the calendar.

But I have a simpler proposal that won’t lead to chaos,and will correct the historical injustices against February

move the last day of January and the last day of March into February to make it a normal month with 30 days,and a respecta ble 31 on leap years().This would not add or subtract a single day from the calendar year.It’s a great idea.And unlike J ulius and Augustus,I won’t even demand a month named in my honor.

29.The first Roman calendar had only 10 months because_________.

A.February hated to be squeezed between the big months

B.the god of war always fought with January and February

C.the Romans did not like the cold winter weather

D.it was Considered unnecessary to divide winter

30.Which of the following is closest to Numa Pompilius’calendar?

31.The writer sounds_____in the passage.

A.sad

B.humorous

C.happy

D. angry

D

One important thing during the pre-Christmas rush at our house was the arrival of my daughter’s kindergarten report car d.She got high praise for her reading,vocabulary and overall enthusiasm.On the other hand,We learnt that she has work to do on her numbers and computer skills,though the detailed handwritten report her teachers prepared is absent of any words tha t might be interpreted as negative()in describing her efforts.A number System indicates how she’s measuring up in e ach area without any mention of passing or failing.

The debate over whether formal grades should be given to kids has long existed.At one level,the advantages and disadva ntages are obvious.A grade system provides a straightforward standard by which to measure how your child is progressing a t school--and how he or she is getting on compared to other children.But as writer Sue Ferguson notes,Grades can deceive.

()The aim should be”to measure learning,not simply what a student can remember on a test.”The two aren’t the same-and if you doubt that as an adult,ask yourself whether you could sit down without any preparation and still pass those high-s chool-level examinations.

If you’re old enough,You’ve lived through this debate before.At one time,it was considered unfair to put children in dire ct competition with one another if it could be avoided.The intention behind that may have been good,but it ignored the fact t hat competition,and the will to come out on top,are essential components of the human condition.

32.Which of the following seems to be weak on the daughter’s kindergarten report card?

A.Reading.

B.V ocabulary.

C.Enthusiasm.

D.Numbers.

33.what did the teachers try to do when preparing the report card?

A.Avoid using negative words.

B.Describe the facts as they really were.

https://www.sodocs.net/doc/074059889.html,e numbers instead of words.

D.Avoid showing weak areas.

34.What does the writer suggest by the underlined part in Paragraph 2?

A.Most adults can pass high-school-level examinations without preparation.

B.There’s no doubt that most high-school-level examinations measure learning.

C.As an adult,you should not doubt your ability to pass high-school-level examinations.

D.It’s difficult for most adults to pass high-school-level examinations without preparation.

35.Which of the following would the writer most probably agree with?

A.Schools should not give formal grades to kids.

B.Schools should give formal grades to kids.

C.Giving formal grades to kids has no disadvantages at a11.

D.It’s unfair to put children in direct competition with one another.

第二节(共5小题,每小题2分,满分10分)

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项Article writing has been a way of conveying information through the web.If you’re a writer, being able to let them stay on your article for more than two seconds is already a success.Your writing style can create more readers for your content if

you know how to capture the attention of readers. 36

Be Direct-to-the-Point

Website writing differs from print writing.People do not want to spend much time on a website because they want to get the information they need.37

Be Informative

Articles for web content are briefly written.They flesh out the information without decorations.Be sure that your articles are not confusingly worded. 38 Make sure you organize your facts logically so that your reader can effectively process them. Be Conversational

39 Be conversational so that readers can grasp what you mean in your article.With quality content,engage your reader s so that your article will have that personal and human touch.

Be Connected

Most article writers just place sentences that state a certain fact to form a paragraph.

However, in readers’hopes,these writers fail to establish a human connection. 40 So it is important to make the connectio n smooth and not abrupt.

A.Stay away from decorations when writing online content.

B.Most readers like to read articles that”speak”to them.

C.Connection will allow the readers’minds to effectively process what is written.

D.Get to your point directly so that your readers can process the information.

E.Here are some important points to consider before writing online.

F.Article writing is a fun way of establishing a connection with a reader and a writer.

https://www.sodocs.net/doc/074059889.html,plex sentences tend to wrongly lead your reader and make them confused.

2018高考英语全国一卷分析

《英语周报》高考试题研究中心专业评析2018年高考英语全国I卷 一、引言 2018年高考英语全国I卷以落实立德树人、服务选拔、教学导向为目标，考查必备知识和关键能力，体现了基础性、综合性、应用性和创新性的考查要求，有利于培养学生的学科素养和核心价值。2018年高考英语全国I卷取材广泛、体裁多样、选材涵盖人与自我、人与社会、人与自然三大主题，全面考查学生能力，充分体现了高考坚持立德树人、发展素质教育的目标。整套试卷的题目类型多样且难易搭配合理，通过科学设置干扰项等，进一步提高了试题的区分度，充分体现了《2018年普通高等学校招生全国统一考试大纲的说明（文科）》中有关“注重能力考查，引导素质教育，力求平稳推进”的命题指导思想，以及“有利于高校选拔考生，有利于中学素质教育”的基本宗旨。 本研究根据《普通高中英语课程标准》（2017年版）和语言测试有关理论进行分析。为了保证试题分析的可靠性，所有数据分析均采用两人独立分析，第三人审核，并协商达成共识的模式。 二、数据统计及分析 《英语周报》高考试题研究中心认真研究了2018年高考英语全国I卷的试题命制，并对各部分试题做了详尽的分析，包括语篇的体裁、主题语境、文章长度、难度、考查技能等，帮助读者更好地理解语篇，了解高考命题思路，从而促进教学、提高学习效率。 阅读理解 表1：阅读理解数据统计

2018年高考英语全国I卷阅读理解涵盖人与自我、人与社会、人与自然三大主题。A篇是四则在美国华盛顿骑自行车游览的旅游指南；B篇是关于精打细算烹饪美食的新闻报道；C篇是关于世界语言种类随着人类社会发展而逐渐减少的说明文；D篇是有关新旧电器使用与能源消耗调查的议论文。这四篇阅读材料的选择“长短适中，由易到难、真实、多类型”。 四篇短文内容的总词数为1176，和去年（1145词）基本持平。平均易读度为49.45，难度高于去年（结合易读度数据，通过对四篇短文的文本以及设题分析可以看出今年阅读理解难度较去年有所增加，影响因素是多方面的，如：C篇中的长难句和专有名词、D篇的话题具有挑战性、设题巧妙、间接性题目较多等）。阅读理解试题的目的是考查学生是否读懂了文章，因此，题干和选项的表述应该通俗易懂、简洁明了，不给学生造成障碍。根据表1，各篇阅读理解的题目长度所占比例基本一致，比较稳定。 本套试卷中的阅读理解试题以理解文中具体信息的考查为主，兼顾理解主旨要义、根据上下文推断单词的含义、根据所读内容作出判断和推理、理解作者的意图等深层次技能的考查。 试卷中题目的设计，有的与原文有直接关系，有的则是间接关系。如果题目和原文的关系是直接的，那么学生就能从原文中直接找到答案，题目的难度自然就比较低。如果题目和原文的关系是间接的，那么学生就不能直接从原文中找到答案，题目的难度自然就比较高。如果选项也是对原文的转述，那么题目的难度会更加大。由此看来，题目和原文的对应关系在一定程度上可以反映试题的难度。从表3可以看出，本套阅读理解中直接性题目和间接性题目的比例为4:11，间接性题目稍多，因而此套试题阅读理解难度稍高。 七选五 七选五阅读材料是一篇结构比较清晰的说明文，考查考生对文章的整体内容和结构以及上下文逻辑意义的理解和掌握，主题是家庭装修时如何选择不同的颜色。正文长度258词，选项长度72词。5处空缺部分中，36题和37题需要填入半句话（即复合句中的从句部分）,以往高考题中也出现过这种情况，我们认为，这种设题方法在一定程度上降低了试题难度； 38、39、40题各需填入1个完整的句子。 《普通高中英语课程标准》（2017年版）指出，学习语篇知识是发展语言能力的基础。语篇知识在语言理解和表达过程中具有重要作用。语篇中各要素之间存在复杂的关系，如句

2016年高考英语全国卷2试卷分析

2016年高考英语全国卷II试卷分析 整套试题重视英语基础知识，听力重新回归，与往年听力整体情况大致相同，全面考查了学生在语境中理解和获取信息的能力。情境真实，信息点丰富，题目设置比较灵活。相对于前几年来说，2016全国卷二的词汇量有所增加，难度略有增加。但是与2015年全国卷来说，基本是持平的，没有难题和怪题。 听力：话题熟悉，注重交际 听力材料是有关日常生活中所熟悉的话题的简短对话或独白，主要考查学生理解主旨和要义，获取事实性的具体信息，简单推断和理解说话者的意图观点或态度的能力。平时抓紧听力训练，该部分不会有大问题。 阅读理解：文体多样，注重实用 阅读理解从文体上来看，与前几年的出题思路一致：一篇广告，一篇说明文，两篇记叙文；考查内容全面，其中以细节理解的考查为主，但是推理判断题比重有所增加，主旨大意题、词义猜测题也均有涉及。A篇属于广告类阅读，介绍了四则娱乐活动广告，难度较小。本题考生可以使用倒序法，先阅读题目，然后在四则广告中按图索骥即可。B篇属于记叙文，讲述作者上艺术课所发生的事情，由此展开如何培养孩子想象力的话题。难度一般。C篇为说明文，说明了一家网站创新了一种新的阅读方式令人耳目一新。文章的内容看似简单，但是题目的设置却有一定难

度，考生如果对文章没有透彻的理解是很难做对的。D篇是一篇记叙文，由一本影集展开，记叙了历史上一次南极探险的事件。文中出现了四个外国人的姓名和大量的地名及专有名词，文章篇幅也较长，词汇量大，这些都增加了学生阅读的难度，稍有不慎就会选错。七选五讲述如何开辟适合自己的花园，重在考查上下文衔接识别。全国版的空或在段首或在段中也有在段尾的，这样的设置增加了试题难度。 完形填空：记叙文体，贴近生活，人情味浓 完形填空是一篇记叙文，故事性强，寓意深刻，贴近生活。故事讲述的是作者起初认为电话的力量是强大的，可以通过它认识千里之外的你，但是电话传递的声音不总是准确的。作者通过自己的亲身经历讲述了这个观点。说明了面对面交流是准确获得信息的方式，有一定的现实意义。全文逻辑清晰，上下文线索明了，做题过程比较符合考生所谓“顺”的预期。词汇辨析考查明显减少。我们不难发现，在整体故事情节比较通畅的情况下，语意辨析的难度会降低，而纯粹的词汇辨析又居于少数，因此今年该题重在考查的就是对于语篇的细致理解，并没有在故事情感线索处及近义词辨析方面过多挖坑增加区分度。全文线索清晰，词汇考查重在语篇理解，词组搭配考查多用基础词汇。本篇完形填空重在考查语篇理解能力，且不在情节上、词汇考查上大做文章的趋势还是愈发明显的。 语法填空：重视实用，考察全面

2020年高考化学试题分类汇编专题05 元素及其化合物 (解析版)

专题05 元素及其化合物 1．[2019新课标Ⅰ] 固体界面上强酸的吸附和离解是多相化学在环境、催化、材料科学等领域研究的重要课 题。下图为少量HCl 气体分子在253 K 冰表面吸附和溶解过程的示意图。下列叙述错误的是 A ．冰表面第一层中，HCl 以分子形式存在 B ．冰表面第二层中，H +浓度为5×10?3 mol·L ?1（设冰的密度为0.9 g·cm ?3） C ．冰表面第三层中，冰的氢键网络结构保持不变 D ．冰表面各层之间，均存在可逆反应HCl 垐?噲?H ++Cl ? 【答案】D 【解析】 【分析】由示意图可知，在冰的表面第一层主要为氯化氢的吸附，第二层中氯化氢溶于水中并发生部分电离，第三层主要是冰，与氯化氢的吸附和溶解无关。 【详解】A 项、由图可知，冰的表面第一层主要为氯化氢的吸附，氯化氢以分子形式存在，故A 正确； B 项、由题给数据可知，冰的表面第二层中氯离子和水的个数比为10—4:1，第二层中溶解的氯化氢分子应少于第一层吸附的氯化氢分子数，与水的质量相比，可忽略其中溶解的氯化氢的质量。设水的物质的量为1mol ，则所得溶液质量为18g/mol× 1mol=18g ，则溶液的体积为18g/mol 1m 0.9ol g/mL ?×10—3L/ml=2.0×10—2L ，由第二层氯离子和水个数比可知，溶液中氢离子物质的量 等于氯离子物质的量，为10 —4 mol ，则氢离子浓度为-4-2102.l 010L mo ?=5×10—3mol/L ，故B 正确；

C项、由图可知，第三层主要是冰，与氯化氢的吸附和溶解无关，冰的氢键网络结构保持不变，故C正确； D项、由图可知，只有第二层存在氯化氢的电离平衡HCl H++Cl—，而第一层和第三层均不存在，故D错误。 故选D。 【点睛】本题考查氯化氢气体在冰表面的吸附和溶解。侧重考查接受、吸收、整合化学信息的能力及分析和解决化学问题的能力，注意能够明确图像表达的化学意义，正确计算物质的量浓度为解答关键。 2．[2019江苏]下列有关物质的性质与用途具有对应关系的是 A．NH4HCO3受热易分解，可用作化肥 B．稀硫酸具有酸性，可用于除去铁锈 C．SO2具有氧化性，可用于纸浆漂白 D．Al2O3具有两性，可用于电解冶炼铝 【答案】B 【解析】A．NH4HCO3受热易分解和用作化肥无关，可以用作化肥是因为含有氮元素； B．铁锈的主要成分为Fe2O3，硫酸具有酸性可以和金属氧化物反应，具有对应关系； C．二氧化硫的漂白原理是二氧化硫与有色物质化合成不稳定的无色物质，不涉及氧化还原，故和二氧化硫的氧化性无关； D．电解冶炼铝，只能说明熔融氧化铝能导电，是离子晶体，无法说明是否具有两性，和酸、碱都反应可以体现Al2O3具有两性。 故选B。 3．[2019江苏]下列有关化学反应的叙述正确的是 A．Fe在稀硝酸中发生钝化B．MnO2和稀盐酸反应制取Cl2 C．SO2与过量氨水反应生成(NH4)2SO3D．室温下Na与空气中O2反应制取Na2O2 【答案】C 【解析】 【分析】相同的反应物，条件不同（如温度、浓度、过量与少量），反应有可能也不同； A．钝化反应应注意必须注明常温下，浓硝酸与Fe发生钝化； B．实验室制备氯气的反应中应注意盐酸的浓度和反应温度； C．过量与少量问题应以少量物质为基准书写产物；
