题目内容
15.It may seem strange that ice itself sometimes can protect crops from frost (霜冻)!Some growers actually spray their crops with water on a freezing night.Water freezes quickly on the plants and then a strange thing happens.As long as ice stays wet,it can't get colder than 0℃,a temperature many plants can stand.If the ice ever became entirely frozen and dry,it might drop many degrees lower,ruining (毁坏) the plants.But continually spraying water on the ice,the growers keep it from going below 0°C even if the air is much colder.This may be unbelievable but it saves the plants.This strange kind of"ice blanket"works only on plants that are strong enough to stand the weight of frozen spray.The system is used even to protect banana plants on some Central American plantations.

分析 在冬天给冰喷水使其在零摄氏度以上,可以保护植物
解答 CDCB
36 C 猜测词义题.根据文章第二段This strange kind of"ice blanket"works only on plants that are strong enough to stand the weight of frozen spray.可知ice blanket仅仅在能支撑喷洒重量的植物上起作用,也就是说ice blanket是被喷洒的一层冰,故选C.
37 D 细节理解题.根据文章第二段The system is used even to protect banana plants on some Central American plantations可知这种系统还被应用于保护中美的香蕉上,因此本文的目的是提出保护植物的建议,故选D.
38 C 细节理解题.根据文章第二段This strange kind of"ice blanket"works only on plants that are strong enough to stand the weight of frozen spray.可知ice blanket仅仅在能支撑喷洒重量的植物上起作用,对于柔弱的玫瑰花树丛是不起作用的,故选C.
39 B 主旨大意题.通读全文可知在冬天给冰喷水使其在零摄氏度以上,可以保护植物,故选B.
点评 一、速读全文,了解大意知主题.
阅读能力一般指阅读速度和理解能力两个方面.阅读速度是阅读最基本的能力.考生必须在十分有限的时间内运用略读、扫读、跳读等技巧快速阅读,搜寻关键词、主题句,捕捉时空、顺序、情节、人物、观点,并且理清文章脉络,把握语篇实质.
二、看题干,带着问题读文章.
首先要掌握问题的类型,客观信息题可以从文章中直接找到答案;而主观判断题考查的是对文章的感情基调等,这类题必须经过对作者的态度、意图以及对整篇文章进行深一层的推理等.其次,了解试题题干以及各个选项所包含的信息,然后有针对性地对文章进行扫读,对有关信息进行快速定位.此法加强了阅读的针对性,提高了做题的准确率.
三、逻辑推理,做好深层理解题.
在实际阅读中,有时作者并未把意图说出来,阅读者要根据字面意思,通过语篇逻辑关系,研究细节的暗示,推敲作者的态度,理解文章的寓义.要求读者对文字的表面信息进行分析、挖掘和逻辑推理,不能就事论事,以偏概全.推理题在提问中常用的词有:infer,imply,suggest,indicate等.
四、猜词悟义,扫除阅读拦路虎.
猜词是应用英语的重要能力.它不但需要准确无误地理解上下文,而且要有较大的泛读量,掌握或认识较多的课外词汇.我们要学会"顺藤摸瓜",通过构词,语法,定义,同位,对比,因果,常识,上下文等线索确定词义.
