英文Summary写作方法、范例及常用句式

摘要是对一篇文章的主题思想的简单陈述。它用最简洁的语言概括了原文的主题。写摘要主要包括三个步骤:(1)阅读;(2)写作;(3)修改成文。 第一步:阅读 A.认真阅读给定的原文材料。如果一遍不能理解,就多读两遍。阅读次数越多,你对原文的理解就越深刻。 B.给摘要起一个标题。用那些能概括文章主题思想的单词、短语或短句子作为标题。也可以采用文中的主题句作为标题。主题句往往出现在文章的开头或结尾。一个好标题有助于确定文章的中心思想。C.现在,就该决定原文中哪些部分重要,哪些部分次重要了。对重要部分的主要观点进行概括。 D.简要地记下主要观点——主题、标题、细节等你认为对概括摘要重要的东西。 第二步:动手写作 A. 摘要应该只有原文的三分之一或四分之一长。因此首先数一下原文的字数,然后除以三,得到一个数字。摘要的字数可以少于这个数字,但是千万不能超过这个数字。 B. 摘要应全部用自己的话完成。不要引用原文的句子。 C. 应该遵循原文的逻辑顺序。这样你就不必重新组织观点、事实。 D. 摘要必须全面、清晰地表明原文所载的信息,以便你的读者不需翻阅原文就可以完全掌握材料的原意。 1 / 19

E. 写摘要时可以采用下列几种小技巧: 1) 删除细节。只保留主要观点。 2) 选择一至两个例子。原文中可能包括5个或更多的例子,你只需从中筛选一至二个例子。 3) 把长段的描述变成短小、简单的句子。如果材料中描述某人或某事用了十个句子,那么你只要把它们变成一两句即可。 4) 避免重复。在原文中,为了强调某个主题,可能会重复论证说明。但是这在摘要中是不能使用的。应该删除那些突出强调的重述句。 5) 压缩长的句子。如下列两例: “His courage in battle might without exaggeration be called lion-like.” 可以概括为:”He was very brave in battle.” “He was hard up for money and was being pressed by his creditor.” 可以概括为:“He was in financial difficulties.” 6) 你还可以使用词组代替整句或者从句。请看下面的例子:“Beautiful mountains like Mount Tai, Lushan Mountain, and Mount Huang, were visited by only a few people in the past. Today, better wages, holidays with pay, new hotels on these mountains, and better train and bus services, have brought them within reach of many who never thought of visiting them ten years ago.” 2 / 19

海外留学英语写作测试中的小词大用

海外留学英语写作测试中的小词大用 朗阁托福考试研究中心 做海外留学英语写作测试教学那么多年,几乎每次课堂中,只要问到学生关于对写作的感受,基本上都会听到差不多的答案,那就是语法和词汇的问题;也就是说大多数学生都认为只要词汇用的高级、有难度,就一定能够得到很高的分数。其实,这只是一个误区,而这个误区在一定程度上也是由于现在国内的教育状况造成的,当学生们已经习惯了这样的考试模式的时候想要进行改变那是比较难的。其实海外留学考试与国内的四六级考试还是有所区别的,在很多高分甚至是满分的作文中,我们都会发现整篇文章都没有一个生词,所以,问题的关键应该是在于如何灵活地运用这些我们非常熟悉的小词,如何让它们在作文中发挥大作用。在下文中,朗阁托福考试研究中心将给大家列举一些在雅思和托福写作中可以用得很精彩的小词以及它们的具体运用。 1.社会生活类 Skip: The poor tend to smoke more and skip breakfast, two factors which have major stress effects on the body. Better of: People of the lower end of the social economic status have stress levels in their bodies that worth 3 times higher than those who are better off. Reputation: Contrary to fears about the violent reputation of some games, there is no firm proof that playing them has a negative impact on children's behavior. Contribution: Video games have a positive contribution for education. Tough: The findings are likely to surprise supporters of tougher regulation of computer games. Midlife review: People need opportunities to make a "midlife review" to adjust to the later stages of employed life, and to plan for the transition to retirement. Update: Others can do voluntary work more effectively if they can update their

Students from the North like pasta, for example, noodles, steamed bread, and dumplings. Most students like fresh fish, seafood and eggs. Most students eat their meals at the school cafeterias.

英语写作用词的准确表达

英语写作用词的准确表达 一个词的意思有两方面:denotation和connotation。Denototion是词的字面意思,正如字典上所定义的一样;Connotation是由词引申联想到的意思和情感。例如country,nation,state和land,它们的字面意思多少有相似之处,都可以译成“国家”,但它们的涵义却相差甚远。Country主要指国土及国民;Nation 强调民族,种族;state多指国家的政府及政府机构;而land指国家虽不够精确,但更富有文学的色彩,比country一词带有更多的感情。初学写作的人有时会选错词,但更多的时候是选词不全错,而是不够准确、地道,导致词不达意,甚至导致冒犯和误解。固此在英语写作中要学会选择准确的词来表达自己的思想。 一般来说,要把握选词的准确性, 可以从下面三方面入手。 一、要有广泛的阅读积累,才能了解词与社会、历史、文化及政治因素的关系,选词时才能符合语言习惯并与社会文化诸多背景一致。例如,英美人对landlord和peasant两词的理解与中国人截然不同。英美人对前者的理解首先是“房东”,然后才是“地主”;而peasant一词对他们来说意味着“粗俗”与“无知”,此词多少带有贬义色彩。再如propaganda一词在中国并不带有西方人所理解的贬意;而First lady (第一夫人)绝不能理解为汉语的原配夫人,因此在写作中应特别注意这类词,否则会导致冒犯和误解。由于东西方社会历史文化的差异,许多词所引申或代表的内容也大相径庭,Phoenix在西方象征“复活”、“再生”,而汉语的这一词却表示“祥瑞”。Peach在汉语中象征“长寿”而在英语中却用以指代“特别讨人喜爱的人或物”。又比如在表示色彩的词中green是青春的颜色,常表示希望、活力,但在英语中green 又与“妒忌” (to be green with envy,green-eyed)和“没有经验的”(a greeh horn)联系起来。如果没有广泛的阅读积累,养成经常查字典的良好习惯,单凭想当然地选词,势必会词不达意。即使同一事物,在美国和英国也可能有不同的表达。例如:corn一词在美国指“玉米”而在英国泛扮“谷物”;“地铁”在英国用tube或under-groud美国则用subway。此类的例子还有pave-ment/sidewalk, Chemists' shop/drug store等。 二、在英语写作中特别要注意区分同义词,选词时要考虑主题、对象及情景(subject, audi-enc, situation)。由于历史的原因,现代英语除本族语外,还包括大量的法语和拉丁来源的饲,这就使英语的同义词相当丰富。总的来讲,英语本族语大多是短词,小词,听起来朴素)亲切,大量用于口头表达:法语来源的词庄重文雅,多与行政、宗教、军事、服饰等有关;拉丁来源的词,书卷味浓, 如ask,question,inter-rogate这三个不同来源的同义词在不同的主题、对象、情景下用法就不一样。 同义词除了来源的不同会影响措词的选择外,它们在程度、感情色彩上也有不同。比如“瘦”可以用slender,slim,lean, thin,underweight,gaunt, lanky,skinny等来表达,而sleder表示“苗条”是褒义的,skinny却是贬义的,underweight则是中性的词。 即使同是褒义词,表达的感情色彩也不同。比如little和petite两个同义词当用来描绘女子时,都意为“个子小”的,但petite同时还有“匀称”的意义,而little更强调“可爱的”或“可怜的”,根据不同的上下文,它还有“纤小”、“娇小”或“弱小”等不同意义。因此在选词表达思想时,一定要分清主题,对象及情景。 另外让中国学生头痛的是一些同义词的习惯搭配。比如large和big都指“大”,但large通常用来修饰诸如number,amount及quantity(a large nunlber of students,a large almount of money,a large quantity of wine,etc)。但象“勇气”,“信心”,”能力”、“智慧”等表示个人素质的名词,人们通常用呷碰而不用big或large来修饰。由此可见,在英语写作实践中,区分同义词的用法是相当重要的。 三、选择措词应把握好英语和汉语词汇无法对应的部分 不是所有的英语词汇都有相应的汉语表达,一些不同的英语词汇也有可能用同样的汉语来表达,这就使我们在用英语来表达思想对面临更多选择上的困难。比如family和home两词都可译成汉语的“家”,但它
