在阅读考试的时候,在做这个考题之前,你需要注意的一些事情。
第一点:和听力不太一样,我们在做阅读题的时候,无论是快速阅读还是仔细阅读,还是选择填空,或者是六级当中的简答题,我们的要求是大家一定要边做边答,做 一题就直接把答案写在答题卡上。尤其是在快速阅读这一部分,为什么这样?如果你是做完了再把答案誊在答题卡上,会出现恰巧9点55分,快速阅读结束的时 候,你正好做完的是第10个题,这时在答题卡上是一片空白,这时监考老师是不会给你任何时间再让你图答题卡的。如果之前的7个题或者是8个题有部分已经在 答题卡上填了下来,也可以抓到部分分,这一点特别重要,大家一定要注意做一点涂一点。
第二点:注意事项我们在做完形填空之前的选择填空和 仔细阅读这部分,大家最好不论是四级还是六级考试,能够从完形填空或者是从改错当中抽取部分的时间,加入到我们的仔细阅读里来。因为仔细阅读这个部分毕竟 是分值特别大,每题是两分,加起来10道题20分,完形填空和改错的分值也比较高,但是这两部分的难度特别大,你想抓分比较不太容易。所以,你割除一部分 时间放在仔细阅读里可能得分效果更好,仔细阅读占的分值比重和能解决的时间相对来说是在整套试题当中占的比例比较高的部分。为什么这么讲?因为毕竟整个仔 细阅读加在一起,包括快速阅读和选择填空的分值非常高,直接关系到你过还是不过。

一、大纲的要求:
对主体细节推理以及态度题有所把握,对阅读速度的要求:每分钟70个单词。
二、六级文章本身的特点:
1、结构:
1)文科文章常有的一些结构
A、现象解释型(文章一开始给出一个现象然后对现象进行解释,一般都会在第一段的末句是一个问句,段末是问号。就是要我们寻找回答,问题就是一个现象,我们就要寻找解释,来做主题。)解释即为文章的主题所在。常被考到的有:现象本身;解释;作者对解释的评价。理科文章解释主题常有两种方式:1)罗列式的2)用实验来解释主题
文中加引号的词,表明该词在原文中有特定的含义,表达并非最表面的意思
问题中出现了一开始就提到的现象时,答案通常针对文章主题。
B、问题解决方案型(文章一开始给出一个问题,对问题给出一个解决方案。典型的文章:2001年6月的第一篇文章。问题—problem 第一问题本身考一道题,第二造成问题的原因是,第三问题的解决方案是,第四作者对解决方案的态度,正评价还是副评价,肯定还是否定。思路比较固定,只要是解决方案一般都是不行的。)
C、结论解释型(在文科文章的数量是最大的。文章一开始给出一结论,然后对结论进行解释,数量极多。)
2)理科文章的结构
A、现象解释型(结构与文科文章不一样,理科文章首句出问号,常暗示指现象,有现象就要寻找解释。)
B、问题解决方案型(成果型在理科文章里很多,2001-6)
C、实验型文章(文科文章可以颠三倒四的把问题反复地说,理科文章一般比较客观,要说明问题一般用实验来说。)
2、体裁,以说明和议论为主。
原因:四级和四级以上的文章具有的特征——academic学术性的,学术性的文章用记叙文说不清楚,只能用说明和议论。
说明文:作者没有太多的观点,只给出一些数据和事实,让你自己去推理、综合。
启发:
1、关注重点不同。对于说明文而言注意文中的定义、概念、重要数据和细节。对于议论文而言注意作者的结论和观点。主要是看作者支持什么反对什么。
2、文章的重心。四级文章无论说明议论,四级文章的重心一般靠前。两种模式:A、一根主线,一开始就摆出文章的主题。对一个方面进行具体论述。B、花开两朵,各表一枝。文章一开始就出现两个概念或者两个方面,文章论述两个方面一般答案里也包含两个方面。
3、句子结构复杂
常见的难句类型:1、多重复合句,重点是以it为形式主语的复合句。要很开地看出重心,主要注意抓主干和断句。(主谓宾)
2)多重并列句,一般并列句可以用and来连接,另一种是肯定否定形式的并列句,比如:not……but , not only……but also, but 和but also 后面的才是作者强调的。
3)经典被动句
4) 倒装句典型结构主要是主系表结构倒装为表系主结构。方法:第一看系动词,第二看第一个词,如果第一个词有形容词性而又不修饰别的词,就肯定是个表语。一般是为了强调表语,所以倒装。This is of great importance. 倒装为 : Of great importance is …… of great 是形容词变名词。
5)双重否定=肯定
6)比较结构 more……than 在more之后才是重点 , less……than 在than后面的是重点.
段首出现比较级一般都会出题的。
三、如何准备六级阅读
1、练习阅读方法,提高阅读速度。传统的三种方法:1)先看文章后作题。是用这种方法应注意三点: 1、注意文章中心与作者基本观点,即抓大的放小的。 2、注意重要细节的位置,第一遍阅读时在了解主题之后知道某个东西在哪里,胜过你知道他是什么。3、阅读速度稍快。不能过分沉迷于原文,速度要快一点。
2)先看问题再读文章 要抓对重点 适用于文章:1、难度较大的文章2、只包含一两段的流水账文章。流水账文章段落少层次感较差,可以先看题目看清问题,确定大概的位置。3、细节题较多的文章。 缺点:对主题把握不够明确。
3) 读一层意思做一道题,读文章做题交叉进行。本方法适用于:1、段落较多的文章2、阅读速度较慢的同学。注意事项:1每次阅读一小段或者一长段的一半2阅读速度比第一种阅读方法要稍慢一些,力求弄清本段意思3每次读新的内容之前,最好把接下来要回答的问题要先看一下。每篇文章为9分钟,读原文要5分钟,做题要4分钟
注意不良的阅读习惯:1逐词指读 正确方法要读意群 2出声阅读
2、分析句子结构 其他可以不看
3、熟悉体型 主题 (main mainly primary primarily中心思想 写作目的 标题)细节(定位原文关注考试原则)词意(包括指带 上下文推断词义 词根 )推理(细节性推理题 infer题型 conclude题型)态度(表示态度的首段选项的含义)
对主体细节推理以及态度题有所把握,对阅读速度的要求:每分钟70个单词。

"Culture shock" occurs as result of total immersion in a new culture.It happens to "people who have been suddenly transplanted abroad."Newcomers may be anxious because they do not speak the language,know the customs,or understand people's behavior in daily life.The visitor finds that "yes" may not always mean "yes",that friendliness does not necessarily mean friendship,or that statements that appear to be serious are really intended as jokes.The foreigner may be unsure as to when to shake hands,when to start conversations,or how to approach a stranger.The notion of "culture shock" helps explain feelings of bewilderment and disorientation.Language problems do not account for all the frustrations that people feel.When one is deprived of everything that was once familiar,such as understanding a transportation system, knowing how to register for university classes,or knowing how to make friends,difficulties in coping whth the new society may arise.
"...when an individual enters a strange culture,he or she is like fish out of water."Newcomers feel at times that they do not belong to and feel alienated from the native members of the culture.When this happens visitors may want to reject everything about the new environment and may glorify and exaggerate the positive aspects of their own culture.Conversely visitors may scorn their native country by rejecting its values and instead choosing to identify with(if only temporatily)the value of the new country.This may occur as an attempt to over-identify with the new culture in order to be accepted by the people in it.

The Colonel ask Ashenden a good many questions and then suggested that he had particular qualifications for the Secret Service. Ashenden knew several European languages and the fact that he was a writer provided excellent cover: on the pretext that he was writing a book he could, without attracting attention, visit any neutral country.
It was while they were discussing this point that the Colonel said,"You know you might get material that would be very useful to you in your work. I'll tell you an incident that occurred only recently. Very dramatic. A foreign government minister went down to a Mediterranean resort to fecover from a cold and he had some very important documents with him that he kept in a despatchcase.
"A day or two after he arrived, he picked up a blonde at some restaurant or other, and he got very friendly with her. He took her back to his hotel, and when he came to himself in the morning the lady and the despatch-case had disappeared. They had one or two drinks up in his room and his theory is that when his back was turned the woman slipped a drug in his glass."
"Do you mean to say that happened the other day?"said Ashenden wearily.
"The week before last."
"Impossible,"cried Ashenden. "Why, we've been putting that incident on the stage for sixty years, we've written it in a thousand novels. Do you mean to say that life has only just caught up with us?"
"Well, I can vouch for the truth of the story." said the Colonel, "And believe me, the government concerned has been put to no end of trouble by the loss of the documents."
"Well sir, if you can't do better than that in the Secret Service," sighed Ashenden, "that I'm afraid that as a source of inspiration to the writer of fiction, it's washout."

There is evidence that the usual variety of high blood pressure is,in part,a familiar disease.Since families have similar genes as well as similar environments,familiar diseases could be due to shared genetic influences,to shared environmental factors,or to both.For some years,the role of one environmental factor commonly shared by families,namely dietary salt(i.e.,sodium chloride),has been studied at Brookhaven National Laboratory.These studies suggest that chromic excess salt ingestion can lead to high blood pressure in man and animals.Some individuals,however,and some rats consume large amounts of salt without developing high blood pressure.No matter how strictly all environmental factors were controlled in these experiments,some salt-fed animals never developed hypertension whereas a few rapidly developed very severe hypertension followed by early death.These marked variations were interpreted to result from differences in genetic constitution.
By mating is successive generations only those animals that failed to develop hypertension from salt ingestion,a resistant strain(the "R" Strain)has been evolved in which consumption of large quantities of salt fails to influence the blood pressure significantly.In contrast,by mating only animals that quickly develop hypertension from salt,a sensitive strain("S" strain)has also been developed.
The availability of these tow strains permits investgations not heretofore possible.They provide a plausible laboratory model on which to investigate some clinical aspects of the human prototypes of hypertension.More important,there might be the possibility of developing methods by which genetic susceptibility of human beings to high blood pressure can be defined without waiting for its appearance.Radioactive sodium 22 was an important "tool" in working out the characteristics of the sodium chloride metabolism.

1.The study of the effects of salt on high blood pressure was carried out ______.
a.as members of the same family tend to use similar amounts of salt
b.to explore the long-term use of a sodium based substance
