题文
根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。Two brightly colored butterflies have just flown by. They seems to be exactly alike, but actually one is a little larger than the other. 1 The smaller one has a wingspread of less than three inches and also a black line on its back wings.
At first sight, it is hard to tell them apart. Would you guess from this that they are different-sized butterflies of the same species? 2 If you said yes to either question, you would be wrong, for these look-alikes belong to quite different families.
The larger insect is the monarch butterfly (黑脉金斑蝶). As a baby insect, the monarch feeds on milkweed, which seems to give the monarch a disagreeable taste and smell. 3 Birds that eat butterflies soon recognize the monarch and quickly learn to leave it alone.
4 Birds would find this insect tasty, but because it looks like the monarch, birds keep away from it. The viceroy’s similarity to the monarch gives it some protection from its enemies and helps it survive.
There are other pairs of look-alike butterflies, bees and moths. In each case, one either has a disagreeable taste or smell, or can give a painful sting (叮咬). The larger is called the model. 5 A.The smaller insect is the viceroy (副王峡蝶), which feeds on the leaves of trees.B.The larger insect has a wingspread (翼长) of up to four inches.C.The bright coloring of the monarch acts as a warning sign to its enemy.D.Birds protect their babies from eating such dangerous enemies.E. The insect that imitates this model for protection is called the mimic(保护色).
F. Or that they are different species of butterflies but close relatives belonging to the same family?
G. Do you like this kind of special species? 题型:未知 难度:其他题型
答案
小题1:B
小题2:F
小题3:C
小题4:A
小题5:E
解析
本文介绍了各种蝴蝶为了保护自己所拥有的不同的保护色。
小题1:B 根据下一句The smaller one has a wingspread of less than…讲述的小一点的蝴蝶的情况,说明本句讲述的应该是大一点的蝴蝶的情况,故B符合上下文。
小题2:F 根据上一句Would you guess from this that they are different-sized butterflies of the same species?他们是同一种类的不同尺寸,还是不同种类的近亲关系。故F项符合上下文结构。
小题3:C 根据下一句Birds that eat butterflies soon recognize the monarch and quickly learn to leave it alone.说明这种明亮的颜色是对敌人的一种警告,故C项正确。
小题4:A 根据上一段The larger insect is the monarch butterfly说明本段应该讲述的是smaller butterfly,故A正确。
小题5:E 这句话是一个归纳总结的话,所有的蝴蝶的颜色都属于保护自己的保护色。故E项符合上下文。
点评:此类文章重在把握上下文之间的逻辑关系,通过前后的意思连贯性及细致性用心的答题,定能完成的很好。
考点
据考高分专家说,试题“根据短文内容,从短文后的选项中选出能填入.....”主要考查你对 [政治经济类阅读 ]考点的理解。政治经济类阅读
政治经济类文章的概念:
要做好这类阅读,平时就要注意了解国内外发生的政治经济大事,掌握一定背景知识,对这类文章的叙述特点及内容安排有一定了解,还要扩展这方面的词汇。阅读这类文章,要抓住文章的核心,即文章整体和各段主要在说什么,也要注意段落之间的逻辑关系。
如何备考政治经济类阅读理解题:
【题型说明】政治经济类阅读文章是高考常选材料之一。该类文章时代气息浓郁,语言鲜活,但熟字新义词、超纲词及专业词语多,长句、难句多。政治类文章大多数是同学们感性趣的内容,读起来倒有似曾相识的感觉,经济类文章读起来就像是雾里看花,文章看完,一头雾水。再加之这类文章的命题侧重于词义猜测、推理判断和文章主旨,同学们对这类题材是望而生畏。
【备考策略】建立心理优势。针对不同体裁的文章,我们要采取相应的阅读方法和技巧。政治类文章多采用记叙文形式,我们可采取“顺读法”,以便抓关键语句,领会文章主旨;而经济类文章则多采用说明文形式,我们则可以采取“逆读法”,先读试题,再从文章中查找有用信息。若遇到的确难读的材料。千万不用着急,因为你觉得难,其他人也一定是同感。在高考前,我们就要有这种心理准备,高考试卷肯定有一、两篇难以阅读的材料。不过,我们平时可以有意识地从报刊杂志上找一些较难的阅读材料来阅读,以培养自己迎难而上的心理素质。
【答题方法】
1、寻找主干:
根据英语中五种基本句型结构,把句子中的主语、谓语、宾语、表语等主要成分找出来,其他成分如定语、状语、补语等则易于理解。找到了句子主干,句子的意思至少明白了一半。
2、剔除从句:
在一个长句中可能会出现若干个从句,在理解时,如果把各个从句剔除出来单独理解,然后把大意拼凑起来,整个长句的意思就会明白六、七分。
3、辨别分句:
一个长句如果是由几个并列、转折、递进、对比关系的分句组成,句中往往有表示这些分句关系的连接词,只要能弄清楚分句和分句之间的逻辑关系,再把各层分句的意思加以连贯,整个长句的句意基本上能跃然脑中。
4、寻找关键词:
如果一个句子看完,一点句意的感觉也没有,下下策就是抓住句中的关键词,通过关键词大体弄懂这个长句的意思。
