名师预测一、AHi, I'm Michael J. Lindell, Inventor, Manufacturer, and President of My Pillow Corporation. Years ago, like you, I found myself extremely frustrated with my pillow going flat. Most pillows are designed to break down. I would wake up in the morning with a sore arm, my neck would hurt, my fingers would be numb, and I would toss and turn all night not knowing why. I tried many different pillows on the market and none of them worked. So, I started to research pillows and study sleep disorders.I was determined to create the world's healthiest, most comfortable, and strongest pillow. My Pillow uses our unique, patented medical fill that stays cool, corresponds to your exact individual needs regardless of sleep position, and stays healthy for your full 10-year guarantee. It is non-allergic, and you can wash and dry it as easily as your favorite jeans.My Pillow is not available in stores. I have spent the last seven years selling My Pillow face-to-face at fairs, expos and events. Hundreds of experts and medical doctors carry and recommend them for their patients. I have been featured on medical talk shows that air around the world. I have sold hundreds of thousands of pillows and have received great gratitude from satisfied customers regarding how My Pillow has changed their lives and provided a more comfortable, restful sleep.And, My Pillow comes in different sizes and is fit for your size andsleeping pattern. So you can be assured that you will have the most comfortable pillow for you.I truly believe it is the best pillow in the world and that if everyone had one and got better sleep, the world would be a much nicer place.文章大意:本文是一篇说明文。

模拟组合练(二十七)Ⅰ.阅读理解(2018河南高三4月毕业班高考适应性考试,D)When it comes to mental illness,many people often find it tough to get the help they need. This is especially true for young students to make the transition(过渡) to college life.“Sometimes,students don’t realize how hard it is to adjust to college,”said Laura Smith, associate dean of students at the University of Texas at Dallas.“You’re not the big fish in your classes anymore;you have all kinds of personal stress;you’re away from home.Dealing with these things is not easy.”Students who are going through these problems sometimes want to reach out.But if students don’t feel comfortable seeking help,many feel that it’s the responsibility of their university to help them.“I really wish that there was more importance placed on how counseling(咨询) centers help students,” said Comnie Trinh.“Counseling services are just as important as academics and sports.”Trinh,27,graduated from Texas Woman’s University in2015.During college,she hosted various workshops on how to handle mental health condition.Trinh used her own story to connect with students who might be facing similar problems.High academic pressures,cultural differences as an Asian American and stressful social situations stood out as some of the most common causes of Trinh’s anxiety.It was only after years of personal problems that she could admit that reaching out isn’t a sign of weakness.“If you feel you can’t connect with other people around you,you should address the issue without shame,” Trinh said.“You’ll find that there are a lot of people out there who sincerely want to help you.”1.The passage can be seen as the author’s reflections upon.A.college lifeB.counseling servicesC.mental healthD.cultural differences2.What’s Trinh’s preferred solution to the problems mentioned?A.Making self-criticism.B.Handing the problems actively.C.Solving the problems on her own.D.Finding the causes of the problems.3.What does the underlined phrase“connect with” in the last paragraph probably mean?A.Get along with.B.Join together with.C.Be related to.D.Get through to.4.What can we learn from the text?A.Counseling services help do research.B.Adjusting to college life is a piece of cake.C.Hosting workshops improves students’ ability.D.Being brave to get help is not a sign of weakness.Ⅱ.七选五(2018重庆七校第三次诊断)How to write about yourselfWriting about yourself can seem embarrassing at first.But don’t worry.1.Just introduce yourself.Writing about yourself can be tough,because you’ve got a lot to say, your whole lifetime of experiences,talents,and skills in a paragraph,or a couple of paragraphs. Whatever kind of writing you’re planning on doing,whatever your purpose is,just think about it like you’re introducing yourself to a stranger.What do they need to know?Start with a short list of your talents and interests.If you’re not sure what to choose to start, or if you’re only allowed to pick one thing for the assignment,2.3.Pick a specific one among many topics,describe it in detail,and use that to introduce yourself.It’s better to pick one thing and use it to describe yourself in lots of detail,than to give someone a big long list of general topics.Use a few good details.When you’ve got a specific topic,describe it specifically,giving us something unique to hold onto.Remember you’re telling us about you.So4.Be modest.Even if you’re very accomplished,talented,or cool,you want to come across like a down-to-earth person.5.List your accomplishments and your successes,but temper(使缓和)them with some more modest language,for example,if you want to say“I’m the best and most dynamic(精力充沛的;有创新思想的) worker at my company right now,so you should want to hire me for my talents”,just try“I was lucky enough to be awarded three‘Employee of the Month’ awards at my present job,more than any other employee” instead.A.try listing out as many of them as possible that will help you decideB.the more details you give,the better it will beC.Be dynamicD.Narrow your topicE.Don’t write about yourself to brag(吹嘘)F.Learn the basics and you’ll be able to make your personal writing stand outG.what seems the most interesting1. 2. 3. 4. 5.Ⅲ.语法填空(2018山东淄博一模)British Prime Minister Theresa Mary May paid an1(office)visit to China from Jan.31to Feb.2.She said in her2(speak)on Jan.31,“With the building of the global comprehensive strategic partnership towards the21st century between China and the UK,the relationship has3 (deep)by people-to-people and cultural exchanges between the two countries.”In exchanges between China and the UK,British tea has become a cultural part that has to be mentioned.Tea,4the important goods of the ancient Maritime Silk Road,was once an important carrier of Sino-British trade relations,and has existed for thousands of years.Throughbusiness and trade5has covered more than10,000kilometers and100years,Chinese tea has officially entered every corner of Europe.The UK,however,is the European country most6 (affect)by tea culture.The popularity of tea-drinking in Britain was first limited to the royal ter,when expensive7(tea)were sold in certain cafes,women were initially not allowed to enter.It wasn’t81706that Thomas Twining founded the world’s first dry tea and coffee shop in London.The tea shop quickly became a favorite place for London women.9(strong)promoted by those fashionable women,10(taste)tea gradually became popular among the upper class of Britain.In the eyes of people who love tea culture all over the world,Twinings tea has become a representative of British tea.1. 2. 3. 4. 5.6.7.8.9.10.Ⅳ.短文改错(2017河北唐山一模)假定英语课上老师要求同桌之间交换修改作文,请你修改你同桌写的以下作文。

2019高考数学二轮专项练习精品--推理证明、复数、算法框图【考纲解读】1.理解复数的基本概念;理解复数相等的充要条件;了解复数的代数表示法及其几何意义、2.会进行复数代数形式的四那么运算、② 了解复数代数形式的加、减运算的几何意义、3.了解合情推理的含义,能利用归纳和类比等进行简单的推理,了解合情推理在数学发现中的作用、4.了解演绎推理的重要性,掌握演绎推理的基本模式,并能运用它们进行一些简单推理、5.了解合情推理和演绎推理之间的联系和差异、6.了解直接证明的两种基本方法——分析法和综合法;了解分析法和综合法的思考过程、特点、7.了解间接证明的一种基本方法——反证法;了解反证法的思考过程、特点、9.了解算法的含义,了解算法的思想;理解程序框图的三种基本逻辑结构:顺序、条件分支、循环、10.理解几种基本算法语句——输入语句、输出语句、赋值语句、条件语句、循环语句的含义、【考点预测】今年高考对本部分知识的命题主要有以下两个方面: 1.复数与算法框图是历年高考的热点内容,考查方式主要在客观题中出现,一般只有一个选择或填空,考查复数的基础知识、算法框图以循环结构为主,难度较低。
2.推理证明也是高考的一个重点内容,考查方式多样,在客观题中主要考查合情推理中的归纳与类比,证明题目多以解答题的一个分支出现,常与数列、导数、不等式等知识结合,理科可能考查数学归纳法,难度较高,将继续强调考查逻辑推理、归纳等能力。
【要点梳理】1.合情推理与演绎推理:合情推理包括归纳与类比,明确演绎推理的三个模式〔大前提、小前提、结论〕.2.直接证明与间接证明:直接证明包括分析法(执果索因)与综合法(执因索果);常用的间接证明方法是反证法,反证法主要用于证明唯一性与否定性命题,其主要步骤是否定结论、证明、得出矛盾、肯定结论.3.(理科)数学归纳法:用来证明与自然数有关的等式、不等式、整除及几何等问题。
证明时,特别注意第二步,要弄清式子的构成规律,充分利用题目中的条件和假设,适当变形。

语言表达之图文转换考向一图画1.讲高考(1)考纲要求要求考生能够读懂图画,具有概括或描写画面的内容,揭示画面蕴含的寓意等能力。
(2)命题规律图画类题目是当前高考的热点,题型主要是概画面的内容,揭示画面寓意、拟标题、谈看法、描写画面、根据画面写对联等。
例【2018年高考天津卷】阅读下面的漫画,按要求作答。
(6分)鲁迅提过,“要极省俭的画出一个人的特点,最好是画他的眼睛”,丰子恺的漫画《村学校的音乐课》却没有画人的眼睛。
你觉得二者矛盾吗?请结合画面说明理由。
【答案】不矛盾。
鲁迅说的“要极省俭的画出一个人的特点,最好是画他的眼睛”,主要是针对文学创作而言,在写作中注重刻画人物的眼睛,更能突出人物的个性。
丰子恺的漫画《村学校的音乐课》,突出的是小学生的嘴巴,很符合漫画的题目中的“音乐课”,因为音乐课主要是唱歌,突出小学生的嘴巴更能突出漫画的主题,所以二者没有矛盾之处。
【解析】【试题分析】本题要求回答丰子恺的漫画《村学校的音乐课》却没有画人的眼睛,与鲁迅的观点矛盾么?在记叙文中,截取最鲜明、最动人、最能反映本质的闪光的瞬间而加以表现的选材方法,称之为截取法。
而“闪光的瞬间”在不同的文章中有不同的表现。
有的在人物的眼睛上,而音乐课的闪光瞬间却在嘴巴上,所以本幅漫画的重点,人物状态中最鲜明、最动人的闪光点不是眼睛,所以没有画人的眼睛。
【考点定位】语言表达简明、连贯、得体、准确、鲜明、生动。
能力层级为表达运用E。
【试题点评】图文转换算是老题型,但2018年天津卷的这题图文转换却“翻新”了。
考生不但要观察漫画,还要分析鲁迅观点所指的意思。
首先观察漫画,读懂漫画的标题,漫画的标题往往是诠释漫画主旨的点睛之笔,对漫画主旨有提示、启发作用;读懂漫画中的对白或说明文字;读懂漫画的构图;读懂漫画中的要素,要素包括:“人”“物”“对白”等。
比如本题的漫画,标题是“村学校的音乐课”,再看漫画中构图组成部分,是老师和学生,进一步把握漫画中突出的细节部分,即凸起的嘴巴,结合音乐课即可知道漫画的用意。
