15、 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Citizenslonger 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,在字数上不符合要求。(2)词 性 转 换。如“Thegrayingof the UnitedStates”，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
16、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
17、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 onones interests.在例举式表格中Find the right schools thatone _73_.根据原句based on ones interests可得知答案用同意句改写替换。即：is/becomes 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 agradu
18、al change in the family unit.The other likelydevelopment will be a change in the proportion of thenations 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。
