33、 读文“三步走” 阅读首尾把握主题句该题型的文章基本上都是“开门见山”并“结尾总结”,因此阅读首尾可以快速把握文章的主题,另外,不少文章都有标题,通过标题我们也基本能够确定文章的主题。 浏览选项明确目标 确定主题后,不要马上通读原文,而是建议先浏览6个选项,圈出选项中的关键词,并将这些关键词作为目标事先记在脑子中,再“以目标为导向”回头读原文,这样就会事半功倍。 细读文章抓住关键了解文章大意并浏览完选项后,再回头细读文章,重点阅读挖空附近的句子,这些句子与挖空处的句子逻辑关系紧密,往往能提供重要的解题线索,再结合选项圈定原文中的线索词,然后匹配选项中的关键词。2) 解题“二步骤” 先定两头,缩
34、小范围 题目中的4个空格,一般来说位置处在段首、段尾的题目较易判定,原因有二:一是信息范围小,解题信息一般集中在本段;二是逻辑关系清楚,段首题多是总领引导句,段尾题多是概括总结句,先做段首尾题有利于缩小排查范围,集中精力对余下的选项细审慎选。 细审中间,依法判断剩余的段中设空选项也并非全都是难判别的,此时仍可凭语感语意,借助文中一些明显的信息点选出或排除1-2个选项,进一步缩小思考范围,对最后难判别的几个选项就要借助一些方法技巧来筛选。2、解题技巧解题时要从三个角度着眼:a. 看位置:是段首、段尾,还是段中题;b. 找词汇:锁定选项与文中信息相关联的词汇;c. 思逻辑:思考选项与文中信息是否符
35、合行文逻辑;1) 读懂段意定两头段首、段尾题 挖空在段首,常是主题句或承上启下句 假如挖空出现在段首,通常为主题句。要认真阅读空后内容,根据段落一致性原则,推断出主题句。若不是主题句,则考虑是承上启下句。 挖空在段尾,常是细节句、结论句或承上启下句挖空出现在段尾,通常是细节句,主要看这一段在讲述什么,这一句还是围绕这个点在写。若是所在段的结论和概括。解题时注意在选项中查找表示结果、结论、总结的关联词(如:therefore, as a result, thus, in short, to sum up, to conclude, in a word)或句子。挖空在段尾的空格也可以起到承上启下的
36、作用,即通过空格把本段与下一段有机地结合起来。这时,我们不光要看空格前面的句子,对于下一段的内容也要特别关注。(段首类的承上启下句同样适用此法)2) 细辨关系定中间段中题一般说来,文章的行文通常需要一定的衔接手段来实现,而该题型的衔接手段主要有以下两种渠道:一是词汇线索,二是行文逻辑。 从词汇线索上判断 词汇线索主要包括代词和词汇复现两种情况。 a. 代词 英语表达中,代词出现的频率极高。代词主要用于指代前面提到的人或物,有时也是为了区别前面提到的名词或概念。巧妙利用这样的指代关系及差异可以准确而快速地解题。 b. 词汇复现 作者在文章中会对同一个概念重复描述,从而使得同样的意思在文章不同的地
37、方重复出现。词汇复现可以指相同词汇的重复使用、同义词和近义词的复现以及同一范畴词汇的复现。解题时可以利用这些词作为解题线索。 从行文逻辑上判断 英语行文离不开逻辑关系,一篇没有逻辑的文章只能是一盘散沙。逻辑关系主要包括:并列关系、递进关系、因果关系、转折或对比关系等。a. 并列关系 表示并列关系的词有:first(ly), second(ly) .; first, then/next .; in the first place, in the second place .; for one thing, for another (thing) .; to begin with, to conc
38、lude 等标志性词语,则表明前后两句是逻辑上的并列关系,空格处很有可能是个并列的句子。b. 递进关系 递进关系主要指英语行文中后句对前句是一种顺承逻辑关系。表示递进关系的词有:too, also, besides, further, furthermore, moreover, apart from, whats more, in addition, as well, to make matters worse, not .but ., not only .but also等。c. 因果关系 表示因果关系的词有:so/therefore, thus, hence, consequently
39、(结果), as a result, for that reason, so/such .that ., so that .等。d. 转折或对比关系 表示转折或对比关系的词有:but, however, yet, while/though, or/otherwise, on the contrary, instead, nevertheless (然而), in contrast/comparison 等。e. 表示解释关系表示解释关系的词有:in other words, in fact, as a mater of fact, for example, for instance, actu
40、ally, that is to say等; 课堂典例: 1Directions: Read the following passage. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.A. With the latest learning toys, construction toys and more, your little ones c
41、an enjoy endless hours of imaginative play.B. LEGO products have always been about providing high quality experiences giving every child the chance to shape their own world through creative play.C. Legos current bricks are made from oil-based plastics.D. Since plastic is so common and so non-eco-fri
42、endly, finding ways to replace it is extremely important.E. The new line of production has reportedly already started with pieces being produced from polyethylene(聚乙烯).F. The overall design of the space is a modern and mature interpretation of a youthful brand.Lego recently announced that they will
43、start producing pieces from sustainable sugar cane. The toys, which will be indistinguishable from classic Legos, will also feature botanical elements like leaves, bushes, and trees. _47_.“We want to make a positive impact on the world around us, and are working hard to make great play products for
44、children using sustainable materials,” said Tim Brooks, vice president, environmental responsibility at the Lego Group, in a statement. “This is a great first step inour ambitious commitment of making all Lego bricks using sustainable materials”._48_. It is a soft, durable and flexible plastic techn
45、ically identical to those produced using conventional plastic. Lego says that we neednt worry about the quality of the new products, as theyve tested the plant-based plastic to ensure that it meets the high standards for quality and safety that consumers expect from the company._49_. Children and pa
46、rents will not notice any difference in the quality or appearance of the new elements, because plant-based polyethylene has the same proterties as conventional polyethylene.The move is part of Legos campaign to use sustainable materials in its core products and packaging by 2030, a move in which the
47、y have already invested $165 million. According to a research report, 4% of the worlds petroleum is used as a raw material to make plastic, and another 4% is used in the plastic-making process. _50_. With this in mind, Lego has partnered with WWF to play their part, joining the Bioplastic Feedstock
48、Alliance(BFA), which supports the responsible development of plastic made from plant material.The LEGO Groups decision to pursue sustainably sourced bio-based plastic represents an incredible opportunity to reduce dependence on limited resources, and their work with the Bioplastic Feedstock Alliance
49、 will allow them to connect with other companies to continue to think creatively about sustainability.【答案】47. C 48. E 49. B 50. D【解析】【分析】这是一篇说明文。主要说明了乐高集团最近宣布将使用可持续性材料来生产玩具,希望对周围的世界产生积极的影响。据报道,新生产线已经开始使用这种原材料生产的聚乙烯塑料。乐高集团决定采用可持续的生物塑料,这是一个减少对有限资源依赖的绝佳机会,他们与生物塑料原料联盟的合作将使他们能够与其他公司联系,继续创造性地思考可持续发展问题。【47
