We have discussed how to simplify a logic function using logic algebra.This method relies on the skill of the individual in applying the appropriate rules.Sometimes it is hard to be sure whether the logical function is already simplest form or not.Now we will introduce a new method, which is graphical, known as the Karnaugh map.It’s a tool for performing the simplification of logic function.2 first, we must know what is the K-map, and how to design it!Usually, the K-map is made up of 3 parts, and the 3 parts are variables, cells and binary numbers.Ok, we can get 2 k-maps, you should note each map includes 3 parts.Please remember the 3 parts, when you design k-maps, each of the parts is essential.we note the first map has 2 variables, it has 4cells, and the second map has 3 variables, it has 8 cells.So in an n-variable k-map, there are 2 to power n cells.4 then please observe the binary numbers on the upper and left side of the k-map.What do you discover from the changed values? Take the numbers on the upper side as example, look at the first map, the numbers is changed from 0 to 1 between adjacent cells, only one-bit is changed, of course, the number just has one-bit.On the second map, each number has 2 bits, the number is changed from 00 to 01, from 01 to 11, from 11 to 10, between the adjacent cells, there is only one-bit in the number changed.If we change the position of the 2 binary numbers, do you think this sequence is right? No!It’s not right, because the number is changed from 01 to 10, two bits are changed.So you should know there is only a single-variable value changed between adjacent cells.This is one of the K-map’s features.5 we look at other features.On the fist map, Cell 1’s adjacent cells are cell 2 and 3, it’s easy to understand.What are the cell 4’s adjacent cells? They are also cell 2 and 3.But on the second map, cell 3’s adjacent cells are cell 1, 4 and 7.This is easy to understand.Now please give the cell 1’s adjacent cells!You may list cell 2 and 3, it’s right, but it’s not all right, because you ignore the cell 5.Do you know what that is on the left side of cell 1? In fact, cell 5 is on the left side of cell 1, of course, cell 6 is on the left side of cell 2.In this case, adjacent cell include the cells located in the symmetric place.I hope everyone should note this.6 this is a 4-variable K-map.Please give the cell 11’s adjacent cells!Now you should know except cell 12 and 15, cell 3 and 9 are cell 11’s adjacent cells.Cell 3 is on the right side of the cell 11, and cell 9 is on the lower side.7 Ok, let’s summarize the feature of K-map.Fist, if a k-map has n variables, it must possess 2 to power n cells.Second, when you design a k-map, please note how to change the binary number on the upper and left side, there is only a single-variable value changed between adjacent cells.Third, it’s easy to find a cell’s adjacent cells, but I must emphasize that you don’t ignore these cells located in the symmetric place.Please care about these, it will easy for you to make use of K-map.8 after discussing K-map, let’s learn how to represent a truth table on k-map.Here is an example.This is a truth table of a 3-variable function, the knowledge about the truth table has been discussed earlier.The key step is to design a K-map, we know the function has 3 variables, the k-map also has 3-varibales, according to the features of k-map, there are 2 to power 3 cells in the K-map, they are 8 cells.Then the binary numbers will be written, you seem to note there is only single-variable value changed between adjacent cells, we have drawn a K-map.The second step is to mapping the logic function.It is an easy work for you to enter the value of the output variable Y in each cell.On the K-map, cell 0 corresponds to row 0, because the variables’ value are same, a is equal to 0, b is equal to 0, c is equal to 0, so we should enter 0 in cell 0.Cell 1 corresponds to row 1, a is equal to 0, b is equal to 0, c is equal to 0, enter 1 in cell 1.so we can draw a conclusion if all variables’ value on the map is same as those in the table, enter output value in corresponding cell.Ok, fig.5.3 gives the complete K-map of the truth table.Look at this example 2, this equation is in SOP form, first we should convert it into standard SOP, and then it can be represented on K-map.Observe this equation, this term and this term are not minterm.Although minterm and SOP form are discussed early, I think it’s necessary to review this knowledge.Minterm is also called standard product form, we look at example 2, the 3 terms are product form.This and this terms are only product form, they are not standard product form.But this term is standard product form.What’s minterm? A function has n variables, if the product term contains n variables, each variable may be in complemented form or in uncomplemented form.The product term is called a minterm or standard product form.11 of course, it’s easy to understand that if a function has n variables, there must be 2 to power n minterms.There are 3 variables A,B,C, so we can write 8 minterms.12 if the logical function is represented as a sum of minterms only, the function is said to be in standard sum of products form.This expression is not in standard SOP form, because this and this term are not minterms, and this expression is in standard SOP form.13 In fact, the logical function can be converted into standard SOP form.We know the C plus the complement of c equal 1, any term multiply 1 equal itself.So if the fist term multiplies this expression, it can be converted into two minterms, the two sides of the equal mark are equivalent.The second term can be converted into two minterms by the same way.We can get a standard SOP form.14 the represent the SOP form on K-map.15 According to minterm’s features, logical 1 corresponds to the original variable, logical 0 corresponds to complement of variable.When a equal 0, b equal 0, c equal 0, we can get this minterm, this term corresponds to this cell.In fact, the K-Map includes all minterms.16 the first term corresponds to this cell, so we enter 1 in this cell.the second term corresponds to this cell, so we enter 1 in this cell.the third term corresponds to this cell, so we enter 1 in this cell.the forth term corresponds to this cell, so we enter 1 in this cell.the fifth term corresponds to this cell, so we enter 1 in this cell.17 Ok.The equation in standard SOP form is represented on K-Map.18 this section is very important.It is well-known that K-map is perhaps the most extensively used tool for simplification of logical function.Ok, let’s look at how to simplify logical function using K-map.We will illustrate every step through a example so that you can understand this method easily.Let’s look at the fist step, Mark those cells with a 1 that correspond to the terms in expression.Here is an equation in standard SOP form.After designing a k K-map, enter 1s in corresponding cells.So we get fig 5.6.19 Form the 1s into the largest valid group.Some conditions limit the largest group.The group must be a rectangle, and must contain 2 to power i cells, i is equal 0, 1, 2, n.n is the number of variables.When you face this K-map, how to make valid group, on the left side, there are 3 ones, on the right side, there are 2 ones.The 3 ones couldn’t form a group, because it is not rectangle, and it has 3 cells, normally, the group should contain 1, 2, 3, or 8 cells.But these 2 ones can form a group, these and these also can form a group.u should remember this cell and this cell are adjacent, this cell is on the left side of this cell, this cell is in the right side of this cell, the two cells are the same.So these 4 cells should form a group, and it also satisfy the demand of form the largest group.ok we have formed two groups Step 3 each 1 on the map must be included in at least one group.The ones already in a group can be included in another group as long as the overlapping groups include noncommon ones.Please note this cell, it isn’t only in the group, but also in this group, it belongs to the two groups, these 2 groups are permitted.Because the 2 overlapping groups include noncommon ones.Except this cell , this group has this cell, this group has this, this and this cells.21 Step 4 will give us a rule about how to produce terms.Identify adjacent ones in a group, then see the values of the variable associated with these cells.If the variables will be different and they gets eliminated.Other variables will appear in ANDed form in the term.This map exist 2 groups.We observe this group first, the value of variable C is not changed, it is equal to 1.the value of A is also not changed, it’s equal to 0, but look at variable B, the value is changed from 0 to 1 between adjacent cells, variable B should be eliminated.The other two Variables A, and C will appear in ANDed form in the term, I have to emphasize that this term is written by the method of producing minterm.0 corresponds to complemented variable, 1corresponds to uncomplemented variable.So we get this term.Then we observe this group include 4 cells, the value of variable B is not changed, the others will be eliminated.We get the complemented B.two groups get 2 terms.22 step5 these terms are ORed to get the simplified equation in SOP form.This equation is previous, and this is simplified equation, in fact, it’s a simplest expression, these two equations are equivalent.Now, we have simplified a logical expression using K-map, do you find it is a simple and efficient method? Remember these 5 steps, they are useful.23 After this chapter, we should appreciate the two points.First, you must know how to design a K-map;it’s a basal and important knowledge.When you design a K-map, you should pay more attention to these details.Second, simplification a logical expression using K-map method, we know this method is simplest and most commonly used method, it’s an essential knowledge in this chapter and easy for you to be operated, I will give you some homework to practice yourselves, they are 7, 12, 16, and 18 on the page 188 and 189 respectively.Please treat them seriously, you will get promoted.

【关键词】英文电影 赏析 跨文化

文化的多元化和全球化，不仅能促进各国间文化交流，同时也会因为文化的差异导致文化冲突日益扩大。现今，虽然开放，但也应懂得选择、取舍。对中国人而言，学习外语必不可少，特别是英语，然而在学习英语时，人们不免会因为文化差异而遇到问题，比如中式英语。就赏析英文电影来说，这不单单只是观众与创作者之间的交流，也是文化与文化间的交流、碰撞，正因如此，在赏析英文电影时，应该置身于相应文化背景中，理解并审视其中奥妙。

一、文化意象

如同中国的诗歌中经常会用特定的意象，来表达特定的情感或者渲染特殊的氛围一样，在电影中也会出现一些意象，这些意象通常被称为文化意象。简单而言，文化意象就是代表特定民族的特殊文化符号。在中国，经常被提及的文化意象有包括长江、黄河在内的自然意象，还有包括龙、凤在内的人文意象。不同的文化意象在不同的国家、不同的文化背景下会呈现出不同的意思。例如，中国的龙在本国是神圣、尊贵的象征，而在英文电影中被译为“gragon”，并且在不同的电影中代表着不同的形象，但这些形象都与中国人对它的理解相差甚远，通常都是贬义。比如，在《怪物史莱克》中，“gragon”是看守城堡，会喷火的怪物：在《假结婚》中“gragon”代表的是凶恶、剽悍的女性或者极其严厉之人：在“Kiss of The Dragon”中“gragon”的吻是一种残酷的杀人绝技……在中国电影中，龙却是英雄的象征，例如《龙行天下》，《卧虎藏龙》等。就从中西方对龙的理解的差异中，不难看出，中西方文化存在着巨大差异，如果以跨文化视角来理解英文电影中的文化意象，就很容易理解不了电影的文化内涵。因此，在赏析英文电影时，一定要突破文化意象差异造成的误解，注意理解、积累英文电影的文化意象。

二、文化背景

把相同的人物、情节，被放在不同的文化背景下，会带来不同的效果，例如，周星驰的经典电影《大话西游》中，至尊宝选择离开紫霞仙子，是因为他肩负着保护师傅西天取经的重任，如果不知道这个背景，就很难理解剧情。由此可见，背景是电影的重要部分，而且理解背景是赏析电影的关键。

因为中西方文化存在明显差异，所以他们各自的电影文化背景也相差甚远。在英文电影中，常将历史事件和宗教文化设置为背景。比如，电影《珍珠港》和《安妮日记》都是以二战为背景。《珍珠港》是以1941年，日本联合舰队袭击美国太平洋舰队基地珍珠港为背景，这也是一部好莱坞杰出的史诗性爱情巨作。而《安妮日记》是一部通过死于集中营的花季少女的笔触，来控诉法西斯战争的罪恶的经典影片。虽然，二战时中国也身在其中，但是不同的国家经历着不同的故事与事故，会产生不同的文化效应，所以赏析这些影片，还需要理解当时相应的西方国家的处境、遭遇。

西方国家比较看重宗教文化，由此也创作出许多经典电影，比如《七宗罪》、《万圣节之夜》、《查理布朗的感恩节》等。其中《七宗罪》是一部根据《旧约全书》内容创作的具备浓烈宗教气息的犯罪型影片。《旧约全书》是基督教的经典书籍，里面记录着，上帝花了七天时间创造出整个世界，而在创造出亚当的第七天，他就用亚当的第七根肋骨创造出夏娃。地域中有七大恶魔，他们是傲慢、妒忌、暴怒、懒惰、贪婪、贪食以及色欲的化身，因此也被视为七宗罪。基于《旧约全书》的这些内容，人们就将数字7与宗教和人类道德联系起来。中国人并非都有宗教信仰，所以，在理解这些影片时，还需了解并理解相关的宗教知识等文化背景。

三、文化价值

文化价值观是民族的核心所在，它不仅放映出一个民族的风俗、性情，还能深度展现一个民族的魅力。在电影中，文化价值也是其核心，不同的文化价值会创造出不同的价值观，也会带给观众不同的享受。

跨文化电影《刮痧》是由美国人误认为刮痧这一中医疗法，是中国人虐待儿童的手段，而引发的关于文化冲突的故事。由于中西方文化价值存在巨大差异，所以，即使是在相同的事件背景下，不同的文化价值观，也会造就出不同的结局。例如《刮痧》中，约翰在听证会上证实许大同打了儿子，并且在约翰眼中他陈述了客观事实，维护了父母与子女间的独立平等，这样做即使令好朋友失去监护权，也没有错。而在许大同眼中，他认为因为讲究面子，儿子打了保罗，自己动手打儿子，根本没有错。由此可知，不同的文化价值会产生不同的态度，所以，在赏析英文电影时，要注意克服文化价值的差异。

四、结束语

赏析英文电影，一方面，可以提高人们的审美水准，帮助他们感受不同文化背景下的不同人文风情；另一方面，对提高人们的文化修养起到潜移默化的作用。赏析电影与看电影不同，赏析电影必须全面挖掘影片背后的文化，深入了解其中的故事脉络，长期以往，人们对不同文化的把握、理解自然有所提升，其综合文化素养也得到极大程度的提升。

英文试讲稿 第7篇

高分考生对学校的吸引力都是一样的，每年高考成绩一出，不仅内地名校四处出击，香港高校也各显奇招，希望将更多的.高分生收罗门下。

据邬慧丽介绍，她所在的学军中学实验班，除了10名左右学生在高考前确定保送到国内各个大学，剩余参加高考的学生中，有25%左右的同学都提交了香港大学的申请表。“目前还不清楚大家的选择，但是据我了解，这其中有一半左右同学是通过清华、北大自主招生的，估计已经签了协议。”

邬慧丽说，她是今年春天香港大学接收内地学生申请时，网上递交申请表格的，当时她已经通过了清华大学(招生办)的自主招生，获得20分的加分。从小学习绘画的邬慧丽，对设计情有独钟，她的梦想一直很明确：考上清华大学建筑系。高考前，小姑娘心里就打算好了，考得上清华，就读清华;考不上，再考虑去香港上大学。

港大面试全英文

高考成绩出来，邬慧丽以总分725分的高分，排名全省理科第九，上清华大学建筑系已经板上钉钉。但6月25日，她还是去参加了港大的面试，原因是“想锻炼一下”。

这次面试，确实让邬慧丽见识到了人外有人。据邬慧丽介绍，港大的面试采取全英文形式，第一轮，由6~7人组成一小组，两名港大老师监考，在进行完各自30秒的自我介绍后，大家开始无领导小组讨论。邬慧丽所在的小组，还有1名衢州二中的学生、3名杭二中学生，和2名萧山中学的学生。当时小组的讨论题目是：你们认为目前世界面临的最严重环境问题是什么?“我们组衢州二中那个同学口语非常厉害。”邬慧丽回忆说。

在“群面”过后，表现比较突出的学生会被要求当场留下进行单独面试，一名外教跟考生进行一对一交流，邬慧丽说，她和外教聊了聊专业方向的问题。

港大录取内地学生，会参看考生高考成绩和面试成绩，从邬慧丽的表现看，被港大录取的几率非常高，父母也征求过她的意见：“港大的国际化程度可能更高，去香港也更能锻炼独立能力，要不要改变选择?”邬慧丽没有接受父母的建议，她觉得港大可能在经济方面的专业更强一些，她想当建筑设计师，想去建筑系强势的学校。(编辑 沈珏)

《匆匆》试讲稿 第8篇

一、师：我们上节课一起朗诵了朱自清先生的《匆匆》，并且让大家用一个词概括一下你对《匆匆》这篇文章的看法或者作者的感情，我总结了一下大家大概写了一下几个字：美、害怕、悲痛、无奈、惋惜

二、师：哪里美? 生：语言美 师：你能从文中找出你认为非常美的句子来吗? 生：燕子去了，有再来的时候;杨柳枯了，有再青的时候;桃花谢了，有再开的时候。师：谁能告诉我，你觉得这个句子为什么美? 生：我觉得这几个句子结构是一样的 师：谁能说得更专业一点，做一个小文学评论家?(口语表达)生：运用了排比的修辞，使文章句式整齐，富有节奏和韵律感 还有呢? 生：其次，我觉得它写出了那种新事物取代旧事物的生命力。师：嗯，非常好，同学们，我们看，文章开头写的句子是美的，是美好的，但是通过上节课的朗诵，我们也能够感受到作者其实是对“时间一去不复返”是非常郁闷的，对时间的逝去是不舍的是无奈的，我们可不可以用一个词来说一说作者这样写的目的何在? 欲抑先扬，为后文写时光匆匆流逝作铺垫

三、师：有的同学说从这篇文章当中读出了悲，那你能告诉我哪里体现出作者内心的悲吗? 我赤裸裸来到这世界，转眼间也将赤裸裸的回去罢?但不能平的，为什么偏要白白走这一遭啊? 我们赤裸裸的来最终又赤裸裸的走，我们为什么要平白无故地走这一遭啊，朱自清先生在跟谁发问?你觉得谁能回答他的问题呢? 好，我们继续看最后一句： 聪明的你，告诉我，我们的日子为什么一去不复返呢? 师：这个句子我们好像见到过一样的句子? 生：聪明的，你告诉我，我们的日子为什么一去不复返呢? 师：好，那现在，聪明的你，回答以下几个问题 1、文章当中作者提出了几个问句 2、作者对提出的问题给出作答了吗? 3、如果给出了，作者给出答案的形式是怎么样的给大家5分钟的时间讨论

师：好，停

师：经过我们刚才的讨论，发现作者在文中一共给出了这样几个问题，那作者自己也给出了一些回答，但是我们看到，作者对自己的回答满意吗?不满意或者说是不确定。

问题：1、聪明的，你告诉我，我们的日子为什么一去不复返呢?2、是有人偷了他们罢：那是谁? 3、又藏在何处呢? 4、是他们自己逃了罢：现在又到了哪里呢?5、去的尽管去了，来的尽管来着;去来的中间，又怎样地匆匆呢? 6、在逃去如飞的日子里，在千门万户的世界里我们能做些什么呢?只有徘徊罢了，只有匆匆罢了 7、在八千多日的匆匆里，除徘徊外，又剩些什么呢? 8、我留着些什么痕迹呢? 9、我何曾留着像游丝样的痕迹呢? 10、我赤裸裸来到这世界，转眼间也将赤裸裸地回去罢?但不能平的，为什么偏要白白走这一遭啊?

那我们看到大部分的问题其实是没有被解答的。好，那我们同学自己想一想，如果你的心中有很多问题得不到回答，你内心会是什么样的感受呢?

生：;郁闷，不开心，生气、师：对，我们看作者的这些问题可是都有关于时间的啊，而时间又是和什么相关的呢? 好，我们再来读这个句子“我赤裸裸地来到这世界，转眼间也将赤裸裸地回去罢?但不能平的，为什么偏要白白走这一遭啊” 我们看，作者的发问是关于时间的，而对我们所有人来讲，逝去的时间又和我们短暂的生命息息相关，我们再联系一下朱自清先生生活的时代，朱自清先生生活的社会是千疮百孔的，但是又是备受压迫的，而自己的时间自己的生命却在一天天流逝，他的内心是苦闷的甚至是痛苦的。

四、好，最后我给大家布置一个任务，自己回去思考：

试着自己给这几个词语排序，并说明理由，要有书面的文字说明，50-100字。

①美②害怕③悲痛④无奈⑤惋惜⑥焦虑
