15、nother test called the Woodcock Johnston Tests of Achievement.可得知。 10. stress and anxiety直接题。根据第三段chewing gum reduces stress and anxiety 理解是前提，而表述是目的和归宿。要正确有效地表述信息要注意以下几点： 一、注意文字的简洁性 有以下几个规律可循： (1)用名词所有格形式“s”代替介词of。如Citizens longer living就巧妙地运用了名词所有格形式“s”， 如用of, 则变成了the longer living of citizens, 在字
16、数上不符合要求。(2)词性转换。如“Thegrayingof the United States”， 在表达时运用词性转换技巧，将原来的名词gray转换成现在分词时，含有动态意义，表示“逐渐变老”， 言简意赅。 (3)句子结构转换。主要通过加工压缩信息抓住要点。言简意赅， 击中要害。因此怎样加工压缩信息就成了广大考生必备的一种技能。一般的， 阅读填空题要掌握以下几种技能： 词形变形能力。主要是看其前后的动词形式再作确认。如果前后都是动词原形那就不变；如果前后是v.ing形式， 那就要随其变形。 删减多余词汇能力。一般主要是删去不影响主要意思表达的修饰词汇。如形容词、副词、冠词等等。如今年湖南高
17、考的第76题删去了creating；第79题去掉了修饰形容词various。 以群体代替个体。如有的将a/an n.变为其对应的复数形式。原意改换能力。或用同义或近义词代替；或用反义词或派生词改换；或用从句改写， 或用意思接近的名词短语代替原句较长的句子。如今年高考题第73题。原句是Some can help find the right schools based on ones interests.在例举式表格中Find the right schools that one _73_. 根据原句based on ones interests可得知答案用同意句改写替换。即： is /beco
18、mes interested in或shows/takes/has interest in；再如短文中的原信息是两个完整的句子： One likely development will be a gradual change in the family unit.The other likely development will be a change in the proportion of the nations workforce.将句子的核心词进行转换，变成“Family unit change”和“Workforce proportion change”， 从而达到“每空不超过3个单
19、词”的要求。二、注意表述的概括性 概括性是英语阅读填空所考查的重点，要求对阅读信息具有较强的综合归纳能力。在解答这类题时，要找出共性，根据标题词的特点表达，平时注意积累典型的概括性词汇。有时不仅需要记清楚一些概括性词汇，还要熟练掌握该词汇的常用搭配，以便迅速锁定最佳词语。三、注意表述的对称性 对称性是英语阅读填空的又一要求。考生必须对试题所在表格中的上下、左右进行研究，挖掘出其表达形式的共性，如名词短语、介词短语、非谓语动词短语及特殊符号等都应该保持一致。 四、注意表达的正确性 正确表达是英语阅读填空的基本要求。考生在找出相关信息后，必须仔细研究，作出正确的表达。务必要避免时态、人称、单复数形式的错误，更不能出拼写、标点符号等低级错误。高考资源网独家高考资源网Ks5uK&S%5#U精品资源，欢迎下载！高考资源网Ks5uK&S%5#U高考资源网高考资源网
