大学英语四六级英语阅读猜词技巧cxl.ppt
大学英语四级,在英语学习中，我们自然会遇到许多生词。这时，许多人立即翻阅字典，查找词义。其实，这种做法是不科学的。它不但费时费力，而且影响阅读速度。事实上，阅读材料中的每个词与它前后的词语或句子甚至段落有着互相制约的关系。我们可以利用语境（各种已知信息）推测、判断某些生词的词义。,一、针对性解释 针对性解释是作者为了更好的表达思想，在文章中对一些重要的概念、难懂的术语或词汇等所作的解释。这些解释提供的信息具有明确的针对性，利用它们猜词义比较容易。,1根据定义猜测词义:如果生词是句子或段落所解释的定义，理解句子或段落本身就是推断词义。例如：anthropology is the scientific study of man.In slang the term jam constitutes a state of being in which a person finds himself or herself in a difficult situation.定义的谓语动词多为：be,mean,deal with,be considered,to be,refer to,be called,be known as,define,represent,signify,constitute等。,2.根据复述猜测词义:虽然复述不如定义那样严谨、详细，但是提供的信息足以使阅读者猜出生词词义。复述部分可以是词、短语或是从句。Semantics,the study of the meaning of words,is necessary if you are to speak and read intelligently.在复述中构成同位关系的两部分之间多用逗号连接，有时也使用破折号，冒号，分号，引号，和括号等。需要注意的是：同位语前还常有or,similarly,that is to say,in other words,namely,or other,say,i.e.等副词或短语出现。Capacitance,or the ability to store electric charge,is one of the most common characteristics of electronic circuits.,Krabacber suffers from SAD,which is short for seasonal affective disorder,a syndrome characterized by severe seasonal mood swings.根据生词SAD后面定语从句which is short for seasonal affective disorder和同位语a syndrome characterized by severe seasonal mood swings,我们可以推断出 SAD含义，即“季节性情绪紊乱症”。,3.根据举例猜测词义：恰当的举例能够提供猜测生词的重要线索。例如：The consequences of epochal events such as wars and great scientific discoveries are not confined to a small geographical area as they were in the past.,二、内在逻辑关系 根据内在逻辑关系推测词义是指运用语言知识分析和判断相关信息之间存在的逻辑关系,然后根据逻辑关系推断生词词义或大致义域。,1 根据对比关系猜测词义：在一个句子或段落中，有对两个事物或现象进行对比性的描述，我们可以根据生词或难词的反义词猜测其词义。例如：Andrew is one of the most supercilious men I know.His brother,in contrast,is quite humble and modest.,表示对比关系的词汇和短语主要是unlike，not，but，however，despite，in spite of，in contrast 和while 引导的并列句等。A good supervisor can recognize instantly the adept workers from the unskilled ones.,2 根据比较关系猜测词义：同对比关系相反，比较关系表示意义上的相似关系。例如：Green loves to talk，and his brothers are similarly loquacious.表示比较关系的词和短语主要是similarly，like，just as，also等。,3 根据因果关系猜测词义：在句子或段落中，若两个事物、现象之间构成因果关系，我们可以根据这种逻辑关系推知生词词义。例如：Tom is considered an autocratic administrator because he makes decisions without seeking the opinions of others.There were so many demonstrators in the Red Square that he had to elbow his way through the crowd.,4 根据同义词的替代关系猜测词义：在句子或段落中，我们可以利用熟悉的词语、根据语言环境推断生词词义。例如：Although he often had the opportunity,Mr.Tritt was never able to steal money from a customer.This would have endangered his position at the bank,and he did not want to jeopardize his future.,Doctors believe that smoking cigarettes is detrimental to your health.They also regard drinking as harmful.,三、外部相关因素 外部相关因素是指篇章(句子或段落)以外的其他知识。有时仅靠分析篇章内在逻辑关系无法猜出词义。这时就需要运用生活经验和普通常识确定词义。,Husband：Its really cold out tonight.Wife:Sure it is.My hands are practically numb.How about lighting the furnace?The snake slithered through the grass.在猜测词义过程中，除了使用上面提到的一些技巧，我们还可以依靠构词方面的知识，从生词本身猜测词义。,1 根据前缀猜测词义 He fell into a ditch and lay there,semiconscious,for a few minutes.Im illiterate about such things.,2 根据后缀猜测词义 例如：Insecticide is applied where it is needed.Then the vapor may change into droplets.（附：常用前缀、后缀）,3根据复合词的各部分猜测词义 Growing economic problems were highlighted by a slowdown in oil output.Highlight或许是一个生词，但是分析该词结构后，就能推测出其含义。它是由high（高的，强的）和light（光线）两部分组成，合在一起便是“以强光照射，使突出”的意思。Bullfight is very popular in Spain.,综上所述，利用各种已知信息推测、判断词义是一项重要的阅读技巧。在实践中，我们可以灵活运用，综合运用上面提到的几种猜测技巧，排除生词的障碍，顺利理解文章的思想内容，提高阅读速度。,常用前缀、后缀,常用前缀,anti-against,opposite 反对，针对 antiwarantibody antiterrorism antianxietyauto-of or by oneself
