根据提供的信息和语言素材设计教学方案,用英文作答。设计任务:请阅读下面学生信息和语言素材,设计20分钟的英语阅读教学方案。教案没有固定格式,但须包含下列要点:●teaching objectives●teaching contents●key and difficult points●major steps and time allocation●activities and justifications教学时间:20分钟学生概况:某城镇普通高中二年级(第一学期),班级人数40人,多数学生已经达到《普通高中英语课程标准(实验)》七级水平。学生课堂参与积极性一般。语言素材:BusinessMotorola set out a special training plan programme for children last week with the aim of developing children's business skills and preparing them for a future as entrepreneurs.Eighty-seven children aged between 12 and 16 from Beijing and Tianjin attended the one-week training programme called Youth Discovery directed by Motorola University's (MU) instructors and marketing specialists. The children learned about dealing with a practical problem-marketing and worked out a marketing plan by themselves. Last week 26 children of Motorola employees in Tianjin completed their training in the MU-Tianjin Learning Center.Through the training programme, children learnt how to get information through different kinds of sources, determine end-user needs, make up messages of value to customers, and communicate using various means and equipment.Educators acted only as team directors, providing children to discover their own answers. The children gave their solutions to Motorola's management and their parents on the last day of the programme.The children, most of whom were primary and middle school students, presented themselves freely. The students said that they preferred the open and practical way oflearning.Youth Discovery, started by Motorola's former president Robert Galvin, designed and carried out by Motorola University, aimed to bring the talents of young people into full play and encouraged them to discover how their skills can contribute to a team to help it reach an aim.
请阅读 Passage l,完成第 21~25小题。Passage 1 "THE SERVANT"(1963) is one of thosefilms that it is impossible to forget. The servant exploits his master'sweaknesses until he turns the tables: the story ends with the a cringing masterministering to a lordly servant. It is hard to watch it today without thinkingof another awkward  rela-tionship-the onebetween business folk and their smartphones.Smart devices are sometimes empowering.They put a world of information at our fingertips. But for most people theservant has become the master. Not long ago only doctors were on call all thetime. Now everybody is. Bosses think nothing of invading their employees '  free time. Work invades the home far morethan domestic chores invade the office.Hyperconnectivity exaggerates the declineof certainty and the general cult of flexibility. Smartphones make it easierfor managers to change their minds at the last moment. Employees find it ever harderto distinguish between "on-time" and "off-time"—and indeed between realwork and makework. None of this is good for businesspeople ' s marriages ormental health. It may be bad for business, too. When bosses change their mindsat the last minute, it is hard to plan for the future.How can we reap the benefits ofconnectivity without becoming its slaves? One solution is digital dieting.Banning browsing before breakfast can reintroduce a small amount ofcivilization. Banning texting at weekends or, say, on Thursdays, can reallyshow the iPhone who is boss.The problem with this approach is that itworks only if you live on a desert island or at the bottom of a lake. LesliePerlow of Harvard Business School argues that for most people the only way to breakthe 24/7 habit is to act collectively rather than individually. One of theworld's most hardworking organisations, the Boston Consulting Group, introducedrules about when people were expected to be offline, and encouraged them towork together to make this possible. Eventually it forced people to work moreproductively while reducing burnout.MsPerlow' s advice should be taken seriously. The problem of hyperconnectivitywill only get worse, as smartphones become smarter and young digital natives takeover the workforce. But ultimately it is up to companies to outsmart thesmartphones by insisting that everyone turn them off from time to time.The author mentions the film in the first paragraph in order to _____ .
案例:阅读下列三位教师关于“直线与平面垂直的判定”的教学片段。教师甲的引入:教师甲:同学们,空间直线与平面有哪几种位置关系?学生边演示边叙述,得到直线与平面的三种位置关系。教师:直线在平面内,直线与平面的平行已研究过,直线与平面相交成为今天要研究的问题。在日常生活中,你见过哪些情景可以抽象成直线与平面相交?举例说明。学生:日光灯的掉线与天花板相交;房子的柱子与天花板相交;插在碗里的筷子与平的碗底相交。教师:想象力丰富。生活中确实有很多例子。例如,墙角与地面(图片展示),小区的建筑,竹竿与水平面以及古诗词中的自然景观“大漠孤烟直”,“一行白鹭上青天”。在直线与平面相交的模型中,你认为哪种相交最特殊?学生:直线与平面垂直。教师:今天我们就研究这种关系。(板书课题)教师乙的引入:教师:(用PPT呈现龙卷风图片)同学们刚进教室看到这样的壮丽图片,联想起“大漠孤烟直”的美景,大家欣赏完之后是否想到立体几何中什么与什么的关系?学生:线面垂直。教师:很好,那生活中有没有这样的例子?学生:看电视时,视线与画面;电线杆与地面垂直。教师:这样的例子很多。比如,大桥桥柱与水面。正因为生活中有很多线与面垂直关系,所以几何中有必要对此进行研究。这堂课就学习直线与平面垂直。(板书课题)教师丙的引入:教师:前面我们研究了直线与平面平行的判定与性质,今天我们要研究直线与平面的其他位置关系。(展示天安门广场上的国旗与旗杆)先请大家看一幅图:天安门广场的红旗迎风飘扬。再看另一幅图:一桥飞架南北,天堑变通途。请大家回答下面的问题。问题:请同学们观察图片,说出旗杆与地面,大桥桥柱与水平面是什么位置关系?学生:垂直。教师:从教学的角度看,就是什么与什么垂直。学生:线与面。教师:你还能举出一些类似的例子吗?想一想。(同时出示课题)学生1:箱的边缘与地面。学生2:立竿见影,竿与地面垂直。教师又展示跨栏跳高架的图片,说明跨栏的支架与地面,跳高架立竿与地面是垂直关系,请大家参照旗杆与地面这种关系画出相应的几何图形。学生画图,教师在黑板上画出图。教师:为什么画成这样呢?这样直观性强,将直线画得与表示平面的平行四边形的一边垂直。教师:接着前面的内容的学习,下面我们要学习直线与平面垂直的定义、判定与性质。问题:(1)三种引入方式各有什么特点?(10分)(2)在(1)的基础上,给出你对课题引入的观点。(10分)
下面是某教师执教《不等式的运用》的教学过程 。  教学的具体环节如下:  (1)揭示知识联系  学生画均值不等式概念图,并展示,交流讨论,丰富概念图 。    (设计意图:引导学生总结梳理与均值不等式相关的知识结构,通过交流讨论,帮助学生完善知识结构 。)  (2)通过正例同化:  例1:如果a,b∈R+且a≠b,求证:a+b>ab+ab 。  例2:已知a,b,c都是小于1的正数,求证:(1-a)b、(1-b)c、(1-c)a中至少有一个不大于 。  (设计意图:利用上述两例,结合一题多解方式,促进学生加深领会基础知识、基本技能、基本方法,并引导他们把专题知识结构同化到原有的认知结构中去 。)  (3)通过反例同化:  例3:求的最小值 。  (设计意图:  ___________________________________________  (4)运用练习强化:  练习题共三组,每组四道:第一组作为当堂练习,即时讲评;第二组为课堂作业,教师部分口头提示;第三组为自习作业,学生简答思路 。  (设计意图:安排难易适当、有梯度的题组,利用变式教学引导学生在完善知识结构的同时回味、消化、强化所学知识 。)  请完成下列任务:  (1)请完成概念图中问号处的不等式;  (2)请补充完例3通过反例同化的设计意图;  (3)关于《不等式的运用》的教学过程,给出你的教学目标设计;  (4)请对上述这位教师执教《不等式的运用》的教学过程作出评价 。
