It is regarded as the pathway to economic prosperity, an instrument for combating unemployment and the driving force behind scientific and technological advance. Given the importance of education for individuals and society, its scope, constituents and configuration have long been the subject of research, studies and discussion. Theoretically, a student is expected to acquire knowledge of a specific subject or profession at school, but throughout the learning process, education should focus on the development of their skills. A successful school leaver should show exceptional abilities to acquire, organize, interpret,

American History 英美概况美国历史

American History ?I. America in the colonial era ?II. The War of Independence ?III. The Civil War ?IV. America during the two World Wars I. America in the colonial era ?Who were the very first Americans? ?Who was the first one discovering the new continent? ?After whom was the new continent named? I. America in the colonial era ?1.The very first Americans were Indians. ●They created their civilization, known as Maya civilization, dominating Mexico and Central America from 4th to the 10th centuries. ●They were the descendants of the Mongoloid (蒙古人种的) people in Asia. ●About 20,000 years ago, they traveled to the North American continent across the Bering Strait (白令海峡). ?2. Christopher Columbus is believed to have discovered America. ●In 1492, Christopher Columbus discovered America. However, he believed he had reached India and called the natives Indians. ?In 1500, Amerigo Vespucci, an Italian navigator, also under the Spanish flag, drew the conclusion that what he found was a new continent. 3. The establishment of colonies ?Since the America was found, the Spanish established many colonies: Florida, Los Angeles, and San Francisco. ?In 1588, the Spanish Armada was defeated by the English navy,which put England in a better position to provide support for its New World colonies. 3. The establishment of colonies ?Between 1607 and 1733 the British established 13 colonies along the east coast of North America. ?These 13 colonies were established in different patterns: ●crown colonies ( 直辖殖民地), ●proprietary colonies ( 业主殖民地), ●charter colonies ( 特许公司殖民地), ●self-governing or compact colonies ( 自治殖民地或契约殖民地). ?1) The first successful English colony in North America was founded at Jamestown, Virginia , in 1607. ?2) In 1620, a group of Pilgrims sailed to the New World in a ship called Mayflower. They arrived at Plymouth, and built the New Plymouth colony in New England. These Pilgrims drew up the epoch-making Mayflower Compact (五月花契约), which was signed by all adult males on the ship. 3. The establishment of colonies ?3) From 1630 to 1643, some 200 ships transported over 20,000 Englishmen to the Massachusetts Bay colony. ?Plymouth remained a separate colony until 1691 when it was combined with Massachusetts Bay colony. Puritans ?People who criticized or wished to "purify" the Church of England. ?"Puritan" refers to two distinct groups: ?"separating" Puritans, radical Protestants, such as the Plymouth colonists, the pilgrims, who believed that the Church of England was corrupt and that true Christians must separate themselves from it; and ?“non-separating” Puritans, such as the colonists who settled the Massachusetts Bay Colony, who believed in

高中英语感叹句的七种基本句型

感叹句的七种基本句型 概念:感叹句通常有what, how引导,表示赞美、惊叹、喜悦、等感情 一、用感叹词what和它所修饰的名词短语置于句首,其他成分次序不变。 ●句型Ⅰ:what + a/an + 形容词+ 单数可数名词+ 主语+ 谓语。 1.The little boy came riding full speed down the motorway on his bicycle. _______ it was! A. What a dangerous scene B. What dangerous a scene C. How a dangerous scene D. How dangerous the scene. 分析:该题考查感叹句的准确运用,也考查名词scene作为单数可数名词的用法。B选项中应该用how代替what; D选项看似正确,但题干中有it was,不能用。因此在A和C中应该用A, 完全符合句型Ⅰ。本题正确答案是A. ●句型Ⅱ:what + 形容词+ 复数可数名词+ 主语+ 谓语。 2. _____ big fish! When did you get them? A. What B. What a C. How C. How a 分析:由于下个句子中的them可得知,上句中的fish 是名词复数,这是因为fish的复数和单数可以同形。根据句型Ⅱ,便知正确答案为A。B选项的迷惑性最大。 ●句型Ⅲ:what + 形容词+不可数名词+主语+谓语。 3. _____ terrible weather we’ve been having these days! A. How a B. What a C. How D. What 分析:题干中的weather是个不可数名词,根据句型Ⅰ,不能选择B和A; 根据句型Ⅲ,正确答案是D。how 类型的感叹句只能跟单数可数名词,不能用C。 二、用感叹词how和它所修饰的词置于句首,其他成分次序不变。 ●句型Ⅳ:how + 形容词+ a/an + 单数可数名词+ 主语+ 谓语。 4. _______ picture it is! A. How wonderful a B. What wonderful C. What wonderful a D. How a wonderful 分析:句型Ⅰ和句型Ⅳ有点共同之处,也就是中心词都是单数可数名词;他们的不同之处是形容词和不定冠词的位置是相反的,由此推断正确答案应该是A。由于picture是单数可数名词,应该排除B;D和C次序不对。 ●句型Ⅴ:How + 形容词+ 主语+ 谓语。 5 . _____ different life today is ______ what it was 30 years ago! A. What a; from B. What; from C. How; from D. How a; from 分析:该题的难度很大,关键是life在句子中的成分。在该句中life是主语,不是is 的表语。根据句型Ⅴ,正确答案是C。部分学生对句子结构不能正确分析,很容易误选A、B和C。 ●句型Ⅵ:How + 副词+ 主语+ 谓语。 6. ______ quickly you walk! A. How B. What C. What a D. How a 分析:quickly是副词,题干中没有名词,正确答案是A。 ●句型Ⅶ:How + 主语+ 谓语+其它! 7. How I wish that every family had a car in China! 总上所述,标准的感叹句主要有以上七种基本句型,如果中心词是可数的复数名词和不可数名词只能用what,不能用how; 但是,当中心词是单数可数名词时,要根据形容词和不定冠词的位置来决定what 和how 的选择;如果中心词是副词或形容词时,只能用how, 不能用what。 如何判断用what还是用how来引导感叹句 方法一:凡是有a,an开头的,多用what; 方法二:凡是形容词直接加名词的,多用what; 方法三:其它一般用how。 典型例题 1)___ food you've cooked! A. How a nice B. What a nice C. How nice D. What nice

离散数学之集合论

第二篇集合与关系 集合论是现代各科数学的基础,它是德国数学家康托(Geog Cantor, 1845~1918)于1874年创立的,1876~1883年康托一系列有关集合论的文章,对任意元的集合进行了深入的探讨,提出了关于基数、序数和良序集等理论,奠定了集合论深厚的基础,19世纪90年代后逐渐为数学家们采用,成为分析数学、代数和几何的有力工具。 随着集合论的发展,以及它与数学哲学密切联系所作的讨论,在1900年前后出现了各种悖论,使集合的发展一度陷入僵滞的局面。1904~1908年,策墨罗(Zermelo)列出了第一个集合论的公理系统,它的公理,使数学哲学中产生的一些矛盾基本上得到了统一,在此基础上以后就逐渐形成了公理化集合论和抽象集合论,使该学科成为在数学中发展最为迅速的一个分支。 现在,集合论已经成为内容充实、实用广泛的一门学科,在近代数学中占据重要地位,它的观点已渗透到古典分析、泛函、概率、函数论、信息论、排队论等现代数学各个分支,正在影响着整个数学科学。集合论在计算机科学中也具有十分广泛的应用,计算机科学领域中的大多数基本概念和理论几乎均采用集合论的有关术语来描述和论证,成为计算机科学工作者必不可少的基础知识。集合论可作为数学学科的通用语言,一切必要的数据结构都可以利用集合这个原始数据结构而构造出来,计算机科学家或许也可以利用这种方法。 本篇介绍集合论的基础知识,主要内容包括集合及其运算、性质、序偶、关系、映射、函数、基数等。 第2-1章集合及其运算 §2-1-1 集合的概念及其表示 一、集合的概念 “集合”是集合论中的一个原始的概念,因此它不能被精确地定义出来。一般地说,把具有某种共同性质的许多事物,汇集成一个整体,就形成一个集合。构成这个集合的每一个事物称为这个集合的一个成员(或一个元素),构成集合的这些成员可以是具体东西,也可以是抽象东西。例如:教室内的桌椅;图书馆的藏书;全国的高等学校;自然数的全体;程序设计语言C的基本字符的全体等均分别构成一个集合。通常用大写的英文字母表示集合的名称;用小写的英文字母表示元素。若元素a属于集合A记作

浅谈数理逻辑在计算机科学中的应用

浅谈数理逻辑在计算机科学中的应用 文章整理编辑---论文文库工作室(QQ1548927986) 摘要:数理逻辑是离散数学课程中研究推理的逻辑学科,它为确定一个给出的论证是否有效提供各种法则和技巧,在计算机科学里用来检验程序的正确性,也可以验证定理和推论,同时在计算机模型、计算机程序设计语言、计算机硬件系统等方面有着重要作用。研究数理逻辑在计算机科学领域中的应用,必须从研究数理逻辑的符号化开始讨论、加以分析、验证结论。 关键词:数理逻辑;命题逻辑;一阶逻辑;推理理论 离散数学是现代数学的重要分支,是研究离散量的结构及相互关系的学科,它在计算机理论研究及软、硬件开发的各个领域都有着广泛的应用。其内容大致包含数理逻辑、集合论、代数结构、组合数学、图论和初等数论6部分,这6部分从不同的角度出发,研究各种离散量之间数与形的关系。本文主要研究数理逻辑部分在计算机科学领域中的应用。 1.为计算机的可计算性研究提供依据 数理逻辑分为命题逻辑和一阶逻辑两部分,命题逻辑是一阶逻辑的特例。在研究某些推理问题时,一阶逻辑比命题逻辑更准确。数理逻辑中的可计算谓词和计算模型中的可计算函数是等价的,互相可以转化,计算可以用函数演算来表达,也可以用逻辑系统来表达。 某些自然语言的论证看上去很简单,直接就可以得出结论,但是通过数理逻辑中的两种符号化表达的结果却截然不同,让人们很难理解,这就为计算机的可计算性研究埋下伏笔。下面举一个简单例子加以说明。 例1 凡是偶数都能被2整除。6是偶数,所以6能被2整除。 可见,一个复杂的命题或者公式可以利用符号的形式来说明含义,来判断正确性,这使得计算机科学中的通过复杂文字验证的推理过程变得简单、明了了。 2.为计算机硬件系统的设计提供依据 数理逻辑部分在计算机硬件设计中的应用尤为突出,数字逻辑作为计算机科学的一个重要理论,在很大程度上起源于数理逻辑中的布尔运算。计算机的各种运算是通过数字逻辑技术实现的,而代数和布尔代数是数字逻辑的理论基础,布尔代数在形式演算方面虽然使用了代数的方法,但其内容的实质仍然是逻辑。范式正是基于布尔运算和真值表给出的一个典型公式。 下面以计算机科学中比较典型的开关电路的设计为实例说明数理逻辑中布尔代数和范式的应用。整个开关电路从功能上可以看做是一个开关,把电路接通的状态记为1(即结果为真),把电路断开的状态记为0(即结果为假),开关电路中的开关也要么处于接通状态,要么处于断开状态,这两种状态也可以用二值布尔代数来描述,对应的函数为布尔函数,也叫线路的布尔表达式。接通条件相同的线路称为等效线路,找等效线路的目的是化简线路,使线路中包含的节点尽可能地少。利用布尔代数可设计一些具有指定的节点线路,数学上既是按给定的真值表构造相应的布尔表达式,理论上涉及到的是范式理论,但形式上并不难构造。 例2 关于选派参赛选手,赵,钱,孙三人的意见分别是:赵:如果不选派甲,那么不选派乙。钱:如果不选派乙,那么选派甲;孙:要么选甲,要么选乙。以下诸项中,同时满足赵,钱,孙三人意见的方案是什么? 解答:把赵,钱,孙三个人的意见看做三条不同的线路,对三条线路化简得到接通状态

英语专业四级作文范文

The advantages and disadvantages of college students----taking part-time job Nowadays it has become fashionable for college students to taking part-time job in their spare time. I think this trend has advantages and disadvantages as well. The advantages of college students taking part-time job are as follows : By taking a part-time job,college students can earn some money for their daily necessities, so they can ease their families' financial burden and become economically independent. And by taking a part-time job, college students can get some working experiences and know how to use their knowledge in practical work , how to cooperate with the others and how to deal with some problems they may face. These experiences are surely helpful to their future work after graduation. However, the disadvantages of college students taking a part-time job can not be neglected. The main disadvantages are that if they spend too much time on their part-time jobs, their academic studies will be affected. They may not have enough time to digest what they have learned in class and they may not have enough time to extracurricular organized by their college after class. Since this trend has both advantages and disadvantages, college students should be careful when they decide whether they should take a part-time job or not. My suggestion is that they had better strike a balance between academic studies and a part-time job.
