高考英语短文理解学案17.docx

1、高考英语短文理解学案17阅读理解技巧一、 先看题干，带着问题读文章。 即先看试题，再读文章。阅读题干，首先要掌握问题的类型，分清是客观信息题还是主观判断题。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，作者未加陈述的观点以及贯穿全文的中心主旨的理解等，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，再将相关信息进行整合、甄别、分析、对比，有根有据地排除干扰项，选出正确答案。此法加强了阅读的针对性，提高了做题的准确率，节省了宝贵的时间。特别适用于对图形表

2、格类题材的理解。 二、 速读全文，了解大意知主题。 阅读的目的是获取信息。一个人的阅读能力的高低决定了他能否快速高效吸收有用信息。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。没有一定的阅读速度就不能顺利地输入信息，更谈不上运用英语。近几年的高考阅读速度大约是每分钟40个词左右。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。 抓主题句这是快速掌握文章大意的主要方法。主题句一般出现在文章的开头和结尾。用归纳法撰写的文章，都是表述细节的句子在前，概述性的句子居后。此时主题句

3、就是文章的最后一句。通常用演绎法撰写的文章，大都遵循从一般到个别的写作程序，即从概述开始，随之辅以细说。这时，主题句就是文章的第一句。当然也有些文章没有主题句，需要读者自己去归纳。主题句往往对全文起提示、启迪、概括、归纳之作用，主旨大意题，归纳概括题，中心思想题往往直接可从主题句中找到答案。 阅读理解（共20小题，每小题2分，满分40分）阅读下面的短文，从每题所给的四个选项(A、B、C、D)中，选出最佳选项。 A Please be advised that Nairobi like any other large city has a security and crime problem.H

It is estim

The entire procedure could take from three to five years to complete. “The nuclear transfer（核子移植）of one species to another is not easy,and the lack of available (capable of being used) panda eggs could be a

15、major problem,”Kraemer believes.“They will probably have to do several hundred transfers to result in one pregnancy (having a baby).It takes a long time and its difficult,but this could be groundbreaking science if it works.They are certainly not putting any live pandas at risk,so it is worth the ef

The most widespread fallacy（谬误）of all is that colds caused by cold.They are not.They are caused by viruses（病毒）passing

21、 on from person to person.You catch a cold by coming into contact,directly or indirectly,with someone who already has one.It cold causes colds,it would be reasonable to expect the Eskimos to suffer from them forever.But they do not.And in isolated arctic regions explorers have reported being free fr

During the First World War soldiers who spent long periods in the trenches （战壕）,cold and wet,showed no increased tendency to catch colds. In the Second World War p

23、risoners at the notorious Auschwitz concentration camp（奥斯维辛集中营）,naked and starving,were astonished to find that they seldom had colds. At the Common Cold Research Unit in England,volunteers took part in Experiments in which they gave themselves to the discomforts of being cold and wet for long stret

25、ld virus was actually dropped in his nose. If,then,cold and wet have nothing to do with catching colds,why are they more frequent in the winter?Despite the most painstaking research,no one has yet found the answer.One explanation offered by scientists is that people tend to stay together indoors mor

No one has yet found a cure for the cold.There are drugs and pain suppressors（止痛片）such as aspirin,but all they do is to relieve the symptoms（症状）. 63.The writer offered examples to support his argument.

30、coldsD Is language,like food,a basic human need?Judging from the result of the violent experiment by a German king.Frederick ,in the 13th century,it may be.Hoping to discover what language a child would speak if the heard no mother tongue,he told the nurses to keep silent. All the babies died before

31、 the first year.But clearly there was more than language deprivation here.What was missing was good mothering.Without good mothering,in the first year of life especially,the capacity to survive is seriously affected. Today no such violent deprivation exists as that ordered by Frederick .Nevertheless

32、,some children are still backward in speaking.Most often the reason for this is that the mother is insensitive（不敏感）to the signals of the baby,whose brain is programmed to map up language rapidly.There are critical times,it seems,when children learn more readily.If these sensitive periods are neglect
