A (2019·潍坊市统一考试)

When traveling on a budget,every dollar counts.Unfortunately,the cost of tickets alone can make a serious hole in your savings.Don't let that stop you from taking your dream vacation,though.According to Jeff Klee,CEO of https://www.doczj.com/doc/179812306.html,,there is a “sweet spot” to get the biggest bang for your buck.

“The most important rule is fairly obvious: don't wait until the last minute,as that rarely works out,”he said in a statement.“But beyond that,you also want to be careful not to buy too early.”

Still,that's easier said than done.Finding the most cost-efficient time to book is tough.Luckily,somebody did the math—so you don't have to.Data crunchers(处理器) from the online travel ageney https://www.doczj.com/doc/179812306.html, surveyed over 917 million fares to determine the day with the cheapest rates.

Here's what they found:while prices tend to stay the same between 320 and 106 days before a trip,they start dropping at the 105-day mark.That said,you might be tempted to book the moment prices drop.But hold on! You'll save even more money by booking precisely 70 days before your trip.According to https://www.doczj.com/doc/179812306.html,,you can save 48 percent of the ticket's total cost by using this trick.After that date,airfares will begin to increase again.And don't even think about booking any later than 20 days ahead of time,as prices will be soaring.

So,what are you waiting for?Start planning your next dream vacation,and book accordingly.Your wallet will thank you—guaranteed.

A New Jersey couple and a homeless man have been accused of making up a feel-good story that raised more than $400,000 through GoFundMe.

The couple,Kate McClure and Mark D'Amico,and the man,Johnny Bobbitt Jr.,face a charge of second-degree theft,Burlington County Prosecutor Scott Coffina said Thursday.

The couple said they met Bobbitt when he gave his last $20 to McClure,who was stranded on Interstate 95 in Philadelphia,so she could put gas in her car,then started the GoFundMe campaign as a way to thank him.

The paying-it-forward story that drove this fundraiser might seem too good to be true,Coffina said at a press conference.

Unfortunately,it was.The entire campaign was based on a lie.

After fees,the money of the campaign netted about $367,000,all deposited into McClure's accounts,Coffina said.Bobbitt received $ 75,000,and within months McClure and D'Amico had wasted their share on buying a car,high-end handbags and trips,Coffina said.They also used it at casinos(赌场),he said.

Coffina stressed that while Bobbitt,a veteran(老兵),deserves thanks for his

service to the country and sympathy for his situation;he was fully involved in the crime,using media to help“promote the dishonest campaign”.

According to Coffina,McClure and D'Amico first met Bobbitt at an off-ramp(驶出匝道) near a casino they regularly went,at least a month before the GoFundMe campaign went live.

They went back to the spot a month later,Coffina said.D'Amico took a picture of McClure and Bobbitt that became the face of the GoFundMe campaign that they started hours later,Coffina said.

2016年10月浙江新高考英语试题及答案

第二部分阅读理解(共两节,满分35分) 第一节(共10小题,每小题2.5分,满分25分) 阅读下列短文,从每题所给的A、B、C和D四个选项中,选出最佳选项,并再答题纸上将该项涂黑。 A Suddenly another thought went through Kate’s mind like an electric shock. An express train was due to go past about thirty minutes later. If it were not stopped, that long train, full of passengers, would fall into the stream. “Someone must go to the station and warn the station-master,” Kate thought. But who was to go? She would have to go herself. There was no one else. In wind and rain, she started on her difficult was. Soon she was at the bridge that crossed the Des Moines River, a bridge also built of wood, just like the bridge across Honey Creek. The storm had not washed this away, but there was no footpath across it. She would have to cross it by stepping from sleeper(枕木) to sleeper. With great care she began the dangerous crossing, sometimes on her hands and knees, hardly daring to look down between the sleepers into the wild flood waters below. If she should slip, she would fall between the sleepers, into the rapidly flowing stream. At last -she never knew how long it had taken her – she felt solid ground under her feet. But there was no time to rest. She still had to run more than half a mile and had only a few minutes left. Unless she reached the station before the express did, many, many lives would be lost. She did reach the station just as the train came into sight. Fortunately, the station-master was standing outside. “The bridge is down! Stop the train! Oh, please stop it!” Kate shouted breathlessly. The station-master went pale. He rushed into the station building and came back with a signal light. He waved the red light as the train came into the station. It was not a second too early. 21. What did Kate decide to do? A. Stop the express train. B. Check the signal light. C. Meet the passengers. D. Visit the station-master. 22. Which of the following words best describes Kate’s journey? A. Fruitless. B. Boring. C. Well-planned. D. Ricky. 23. Why did the station-master turn pale? A. He suddenly fell ill. B. He realized the danger. C. He discovered his mistake. D. He became over-excited. B The Crowne Plaza Hotel in Copenhagen is offering a free meal to man guest who is able to produce electricity for the hotel on an exercise bile linked to a generator(发电机). The idea is to get people fit and reduce their carbon footprint. Guest will have to produce at least 10 watt hours of electricity – roughly 15 minutes of cycling for someone of average fitness. Guests staying at Plaza Hotel will be given meal tickets worth $36 once they have produced 10 watt hours of electricity. The bicycles will have smart phones attached to the handlebars measuring how much power is being generated for the hotel. The plan, a world-first, will start on 19 April and run for a year. Only guest staying at the hotel will be able to take part. Frederikke Toemmergaard, hotel spokeswoman, said, “Many of our visitors are business people who enjoy going to the gym. There might be people who will cycle just to get a free meal, but generally I don’t think people will take advantage of our programme.” Copenhagen has a long-standing cycling tradition an 36% of locals cycle to work each day, one of the highest percentages in the world, according to the website visitcopenhagen.dk. US environmental website https://www.doczj.com/doc/179812306.html, recently voted Copenhagen the world’s best city for cyclists. “Because Copenhagen is strongly connected with cycling, we felt the bicycle would work well as symbol of the hotel’s green profile(形象).” If successful, the electric bicycle meal programme will be spread to all Crowne Plaza hotels in the UK, the hotel said in a statement. 24. What is the main purpose of the free meal programme? A. To promote the hotel’s green concept. B. To make the city known to the world. C. To attract people to the hotel restaurant. D. To get guests to stay longer at the hotel. 25. How can a participant get a free meal? A. By becoming a professional cyclist. B. By cycling to produce some electricity.

高中阅读理解细节题解题技巧及练习

阅读专题-----细节题 一、题型特点与命题方式 所谓细节题,是指原文提到了某事物、现象或理论,题干针对原文具体叙述本身发问。细节事实理解题 主要考查考生对文章中某一些特定细节或文章的重要实事的理解能力。它一般包括直接理解题和语义理解题 两种。直接理解题的答案与原文直接挂钩,从阅读材料中可以找到。这种题难度低,只要学生读懂文章,就 能得分,属于低层次题。而语义理解题须将题目信息与原文相关信息进行语义上的转换才能得出结论。这类 题目要求考生能理解原文中某个短语或句子的含义,从而找到与答案意思相同的词语和句子。 这类试题旨在考查考生对事实细节的确定。这类试题一般只针对文章中某一特定的细节,也可能涉及若 干个细节,或者针对文章的主要事实,或利用图形图表或地图来表示信息等。此类试题一般又可分为两类: 一是直接理解题,答案可在原文中直接找到;二是词义转换题,答案是原文中有关词语和句子的转换,而不能 在原文中直接找到。 一般包括直接理解题(在原文中可直接找到答案,常用who, what, when, where, why和how等提问。)语义转化题(需要将题目信息与原文相关信息进行语义上的转换,两者存在表达上的差异,有时需要进行加工 或整理后方能得出结论)、数字计算题、排列顺序题、图表图画题等。抓住文段中的事实和细节是做好该题 型的关键,也是做好其它类型问题的基础。这类题型的题干常为: When / Where did the story happen? Which of the following statements is (not) correct? Which of the following statements is (not) mentioned in the passage? Which is the right order of the events given in the passage? All the statements are true except… Which of the following statements is true/NOT true/false, according to the passage? Choose the right order of the events given in the passage? 该题型几乎都可以在文章中直接找到与答案有关的信息,或是其变体。所以,搜查信息在阅读中非常重 要,它包括理解作者在叙述某事时使用的具体事实、数据、图表等细节信息。在一篇短文里大部分篇幅都属 于这类围绕主体展开的细节。做这类题一般采用寻读法,即先读题,然后带着问题快速阅读短文,找出与问 题有关的词语或句子,再对相关部分进行分析对比,找出答案。 二、解题思路与应试技巧 细节题是针对文中某个细节、某句话或某部分具体内容设置问题,正确答案的根据一定可以在原文中找 到,即原文的改写往往成为正确选项。 通常细节题的正确选项有以下特征: 1、对原文句子中的关键词进行替换。把原文中的一些词换成意义相近的词,成为正确选项。 2、词性或者语态的变化。把原文中的一些词变换一下词性,或者改变原文句子的语态,给考生制造障 碍。 3、语言简化。把原文中的复杂语言现象进行简化,成为正确答案。 4、正话反说。把原文中的意思反过来表达而成为正确选项(适用于寻找错误选项的题目)。 干扰项也是以文章中的某个细节设题,若不仔细辨别,很容易把它当成正确选项。干扰项有以下特征: 1、将原文内容扩大或缩小。把原文中的限定词去掉或替换,使该选项看似正确,实际上却是错误选项。 2、把未然当已然。改变文中某句话的时态,如把将来时变成现在时,把未发生的事情当成已发生的事 情。 3、无中生有。即选项内容是根据主观想象或推测得出的结论,而文中并未涉及。 4、偷换概念。把原来做该事的“张三”换成“李四”,所述细节确实与原文一致,一不小心就会误选。 5、文不对题。这类题最不容易辨别,选项中的描述与原文完全一致,确属原文中的一个细节,这时要 回到题干,看该选项是否能回答题干所提的问题。

《数字图像处理》习题参考答案

《数字图像处理》习题参考答案 第1 章概述 连续图像和数字图像如何相互转换答:数字图像将图像看成是许多大小相同、形状一致的像素组成。这样,数字图像可以 用二维矩阵表示。将自然界的图像通过光学系统成像并由电子器件或系统转化为模拟图像(连续图像)信号,再由模拟/数字转化器(ADC)得到原始的数字图像信号。图像的数字化包括离散和量化两个主要步骤。在空间将连续坐标过程称为离散化,而进一步将图像的幅度值(可能是灰度或色彩)整数化的过程称为量化。 # 采用数字图像处理有何优点答:数字图像处理与光学等模拟方式 相比具有以下鲜明的特点: 1.具有数字信号处理技术共有的特点。(1)处理精度高。(2)重现性能好。(3)灵活性高。 2.数字图像处理后的图像是供人观察和评价的,也可能作为机器视觉的预处理结果。 3.数字图像处理技术适用面宽。 4.数字图像处理技术综合性强。 数字图像处理主要包括哪些研究内容答:图像处理的任务是将客观世界的景象进行获取并转化为数字图像、进行增强、变换、 编码、恢复、重建、编码和压缩、分割等处理,它将一幅图像转化为另一幅具有新的意义的图像。 ] 讨论数字图像处理系统的组成。列举你熟悉的图像处理系统并分析它们的组成和功能。 答:如图,数字图像处理系统是应用计算机或专用数字设备对图像信息进行处理的 信息系统。图像处理系统包括图像处理硬件和图像处理软件。图像处理硬件主要由图像输入设备、图像运算处理设备(微计算机)、图像存储器、图像输出设备等组成。软件系统包括操作系统、控制软件及应用软件等。 。 $ 图数字图像处理系统结构图 1

常见的数字图像处理开发工具有哪些各有什么特点 答.目前图像处理系统开发的主流工具为Visual C++(面向对象可视化集成工具)和MATLAB 的图像处理工具箱(Image Processing Tool box)。两种开发工具各有所长且有相互间的软件接口。 Microsoft 公司的VC++是一种具有高度综合性能的面向对象可视化集成工具,用它开发出来的Win 32 程序有着运行速度快、可移植能力强等优点。VC++所提供的Microsoft 基础类库 MFC 对大部分与用户设计有关的 Win 32 应用程序接口 API 进行了封装,提高了代码的可重用性,大大缩短了应用程序开发周期,降低了开发成本。由于图像格式多且复杂,为了减轻程序员将主要精力放在特定问题的图像处理算法上,VC++ 提供的动态链接库支持BMP、JPG、TIF 等常用6种格式的读写功能。 MATLAB 的图像处理工具箱M ATLAB 是由M athWorks 公司推出的用于数值计算的有力工具,是一种第四代计算机语言,它具有相当强大的矩阵运算和操作功能,力求使人们摆脱繁杂的程序代码。MATLAB 图像处理工具箱提供了丰富的图像处理函数,灵活运用这些函数可以完成大部分图像处理工作,从而大大节省编写低层算法代码的时间,避免程序设计中的重复劳动。MATLAB 图像处理工具箱涵盖了在工程实践中经常遇到的图像处理手段和算法,如图形句柄、图像的表示、图像变换、二维滤波器、图像增强、四叉树分解域边缘检测、二值图像处理、小波分析、分形几何、图形用户界面等。但是,MATLAB 也存在不足之处限制了其在图像处理软件中实际应用。首先,强大的功能只能在安装有M ATLAB 系统的机器上使用图像处理工具箱中的函数或自编的m文件来实现。其次,MATLAB 使用行解释方式执行代码,执行速度很慢。第三,MATLAB 擅长矩阵运算,但对于循环处理和图形界面的处理不及C++等语言。为此,通应用程序接口A PI 和编译器与其他高级语言(如C、 C++、Java 等)混合编程将会发挥各种程序设计语言之长协同完成图像处理任务。API 支持 MATLAB 与外部数据与程序的交互。编译器产生独立于M ATLAB 环境的程序,从而使其他语言的应用程序使用MATLAB。 常见的数字图像应用软件有哪些各有什么特点答:图像应用软件是可直接供用户使用的商品化软件。用户从使用功能出发,只要了解 软件的操作方法就可以完成图像处理的任务。对大部分用户来说,商品化的图像应用软件无需用户进行编程,操作方便,功能齐全,已经能满足一般需求,因而得到广泛应用。常用图像处理应用软件有以下几种: 1.PHOTOSHOP:当今世界上一流的图像设计与制作工具,其优越性能令其产品望尘莫及。PHOTOSHOP 已成为出版界中图像处理的专业标准。高版本的 PHOTOSHOP 支持多达 20 多种图像格式和TWAIN 接口,接受一般扫描仪、数码相机等图像输入设备采集的图像。PHOTOSHOP 支持多图层的工作方式,只是 PHOTOSHOP 的最大特色。使用图层功能可以很方便地编辑和修改图像,使平面设计充满创意。利用PHOTOSHOP 还可以方便地对图像进行各种平面处理、绘制简单的几何图形、对文字进行艺术加工、进行图像格式和颜色模式的转换、改变图像的尺寸和分辨率、制作网页图像等。 2.CorelDRAW:一种基于矢量绘图、功能强大的图形图像制作与设计软件。位图式图像是由象素组成的,与其相对,矢量式图像以几何、色彩参数描述图像,其内容以线条和色块为主。可见,采用不同的技术手段可以满足用户的设计要求。位图式图像善于表现连续、丰富色调的自然景物,数据量较大;而矢量式图像强于表现线条、色块的图案,数据量较小。合理的利用两种不同类型的图像表现方式,往往会收到意想不到的艺术效果。CorelDraw是 2

专题限时集训3 细节理解之数字计算 2021届新高考英语二轮复习习题

专题限时集训(三) 细节理解之数字计算 A (2019·潍坊市统一考试) When traveling on a budget,every dollar counts.Unfortunately,the cost of tickets alone can make a serious hole in your savings.Don't let that stop you from taking your dream vacation,though.According to Jeff Klee,CEO of https://www.doczj.com/doc/179812306.html,,there is a “sweet spot” to get the biggest bang for your buck. “The most important rule is fairly obvious: don't wait until the last minute,as that rarely works out,”he said in a statement.“But beyond that,you also want to be careful not to buy too early.” Still,that's easier said than done.Finding the most cost-efficient time to book is tough.Luckily,somebody did the math—so you don't have to.Data crunchers(处理器) from the online travel ageney https://www.doczj.com/doc/179812306.html, surveyed over 917 million fares to determine the day with the cheapest rates. Here's what they found:while prices tend to stay the same between 320 and 106 days before a trip,they start dropping at the 105-day mark.That said,you might be tempted to book the moment prices drop.But hold on! You'll save even more money by booking precisely 70 days before your trip.According to https://www.doczj.com/doc/179812306.html,,you can save 48 percent of the ticket's total cost by using this trick.After that date,airfares will begin to increase again.And don't even think about booking any later than 20 days ahead of time,as prices will be soaring. So,what are you waiting for?Start planning your next dream vacation,and book accordingly.Your wallet will thank you—guaranteed. 【语篇解读】本文介绍了购买便宜飞机票的方法和策略。 1.When can we book our plane tickets to save the most money? A.The later,the better. B.As early as possible. C.105 days before our trip. D.70 days before our trip. D[考查细节理解。根据第四段的内容尤其是第四句“You'll save even more

1、考虑如下所示图像子集: (1)令V={0,1},计算p 和q 之间的4,8,m 通路的最短长度; (2)令V={1,2},仍计算上述3个长度。 2、对于离散的数字图像,则变换函数T(rk)的离散形式可表示为: ∑∑==-=-==k j j k j j r k k n MN L r p L r T s 001)()1()( 上式表明,均衡后各像素的灰度值sk 可直接由原图像的直方图算出。 例 假定有一幅总像素为n=64×64的图像,灰度级数为8,各灰度级分布列于表中。对其均衡化计算过程如下。若在原图像一行上连续8个像素的灰度值分别为:0、1、2、3、4、5、6、7,则均衡后,他们的灰度值为多少? 3 、

4、在位图切割中,就8比特图像的位平面抽取而言 (1)通常,如果将低阶比特面设为零值,对一幅图像的直方图有何影响? (2)如果将高阶比特面设为零值将对直方图有何影响? 答:(1)如果将低阶比特面设为零,图像的不同灰度级的个数会减少,即某些灰度级的像素数会丢失,而像素总数是不变的,丢失的像素转移到其它未丢失的灰度级上,从而图像的直方图密度变低; (2)当图像高阶比特面设为零,高灰度级的像素会丢失,丢失的像素都转移到低灰度级上,从而导致图象直方图只有低灰度区,高灰度区直方图均为零。

浙江省新高考英语写作学法指导

高考英语写作指导 一、应用文写作 评分标准总分15分,按5个档次给分。 1.评分时,先根据文章的内容和语言初步确定其所属档次,然后以该档次的要求来衡量、确定或调整档次,最后给分。(先锁定档次,再具体给分) 2.词数少于60词和多余100的,从总分减去2分。 3.评分时,应注意的主要内容:内容要点、应用词汇和语法结构的丰富性和准确性及上下文的连贯性。 4.拼写和标点符号(切忌逗号不能连接两个完整的句子,要么用分号,要么用连词)是语言准确性的一个方面,评分时,应视其对交际的影响程度予以考虑。 5.如书写较差,以致影响评阅,将分数降低一个档次。(注意保证书面整洁,不要有太多乱涂乱画的痕迹。) 档次描述 第五档(13-15分)完全覆盖了试题规定的任务;覆盖所有要点;应用了较多的语法结构和词汇;语法结构或词汇方面有些许错误,但为尽力使用复杂语法结构或较高级词汇所致;具备较强的语言能力;有效地使用了语句间的连接成分,使全文结构紧凑;完全达到了预期的写作目的。 第四档(10-12分)完全完成了试题规定的任务;虽漏掉了1-2个次重点,但覆盖所有主要内容;应用的语法结构和词汇能满足任务的要求;语法结构或词汇方面应用基本准确,有些许错误主要因尝试使用较复杂语法结构或词汇所致;应用简单的语句间的连接成分,使全文结构紧凑;完全达到了预期的写作目的。 第三档(7-9分)基本完成了试题规定的任务;虽漏掉一些内容,但覆盖所有内容;应用的语法结构和词汇能满足任务的要求;有一些语法结构或词汇方面的错误,但不影响理解;全文内容连贯,整体而言,基本达到了预期的写作目的。 写作步骤 (1)仔细审题,明确写作要求。那审题需要审什么?一审文体要求。了解题目要求写作的文体是应用文之书信、通知,演讲稿等。熟悉文体后即可确定全篇的写作格式与写作风格及段落结构之间的逻辑关系等。二审人称与时态。浏览题干要求后明确全文写作时态和人称,行文中做到两条主线贯穿始终:上下文人称统一,时态前后照应。三审要点。审题时弄清文章要点,各要点之间有什么联系。 (2)简单列出提纲,构建写作框架。根据文章要求,简单地想一想文章怎么构建,一些要点应该怎么表达,如句型、句式、词汇等。 (3)胸中有话,动手开篇成文。成文过程中设想一下平时学过的比较高级词汇和句型,如定语从句、状语从句、主语从句等。对于句型和词汇,有把握就用起来,没把握为了保险期间可以选择不用。 (4)细心通读,反复核查。要点是否遗漏、句子之间的衔接和过渡是否自然(多用连词,但是要明确句子间的关系,不要出现误用)语言是否得体,有无语法、拼写、表达错误。不要写几个词,点一下,切忌,在英文中一点就代表一个句号,这样会影响书面整洁。 二、读后续写
