    Three-Dimensional (3D) movies have been becoming more and more popular in recent years.It seems 3D TV sets may be going into family households in the near future.While new digital 3D technology has made the experience more comfortable for many, for some with eye problems, long 3D viewing may result in an aching head, doctors say.

    "There are a lot of people walking around with very minor eye problems, which under normal situations, the brain deals with naturally," said Dr Michael Rosenberg, an ophthalmologist (眼科医师) in Chicago.He said in a 3D movie, these people face a completely new sensory experience."That translates into greater mental effort, making it easier to get a headache," Rosenberg told Reuters.
    In normal vision, each eye sees things at a slightly different angle."When that gets processed in the brain, that creates the perception (感觉) of depth," said Dr Deborah Friedman, an ophthalmologist in New York.The images people see in three dimensions in the movies are not calibrated (校准的) in the same way that their eyes and brain are."If your eyes are a little off to begin with, then it's really throwing a whole degree of effort that your brain now needs
    to exert (竭尽全力)," he said.                    
    Dr John Hagan, a Kansas City ophthalmologist, said some people who do not have normal depth perception cannot see in 3D at all.He said people with eye muscle problems, in which the eyes are not pointed at the same object, have trouble processing 3D images.
    Rock Heineman, a spokesman for RealD, a provider of 3D equipment to theaters, said headaches and nausea were the main reasons 3D technology never took off
    Heineman said older 3D technology used two film projectors(放映机), one that projected a left-eye image and one that projected a right-eye image.Three-D glasses would allow viewers to see a different image in each eye.
    "People often complained of headaches and it was really because the projectors weren’t lined up," Heineman said.
    Now his company has developed a new single digital projector, which switches between the left and the right-eye image 144 times a second, to help overcome some of the old problems.
    "By going to a single digital projector, those problems were solved," he said.Friedman said he thinks most people will do fine with 3D movies and with 3D TVs, but Rosenberg said people may quickly tire of the novelty (新鲜事物)."I suspect there will be a lot of people who say it's sort of neat, but it's not really comfortable," he said.
    小题1:The text is mainly about ____.
    A.the reasons why people like 3D movies
    B.how to improve 3D technology
    C.the development of 3D technology in recent years
    D.causes of headaches and nausea when people watch 3D movies
    小题2:The underlined phrase "took off" could be replaced by "______".
    A.became popular
    B.flew in the sky
    C.left hurriedly
    D.removed one's clothes
    小题3:This article implies that _____.
    A.people do not like new things like 3D movies
    B.3D TVs will completely take the place of old TV sets
    C.3D technology is the most important technology ever
    D.those with eye muscle problems should not watch 3D movies
    小题4:We can learn from what Rosenberg said in the last paragraph that
    A.a single digital projector could solve all the problems with 3D technology
    B.people will gradually become comfortable with 3D movies and TVs

  • 政治经济类阅读
  • 历史文化类阅读

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。


什么是历史文化类阅读:

本类题型常用的方式是夹叙夹议。叙述的目的是为了议,所以要把握其议才是主要方面。阅读这类文章,先弄清其引入的话题,再弄清里面人物对其不同的看法,然后理解作者本身对话题的观点看法或思考。


历史文化类阅读技巧:

题型说明】历史文化类阅读理解文章属高考常选材料之一。这类文章常涉及历史、文化、法制、宗教等方面的文学艺术、发明创造、文化遗产保护、宗教与文化、风俗与习惯、道德与法制、中外文学名著节选、等等。这类材料的命题点往往落在主旨大意题、事实细节题上。
答题方法】在做这类阅读理解题时,我们应注意以下几个方面:
1、采用先题后文:先读题目,再带着问题读文章。这类阅读理解文章相对来说事实细节题稍多一点,如果带着问题读文章,有利于我们抓细节。
2、先做细节题。因为做完了局部性的事实细节题后,自然会加深我们对文章的理解,这样更有利于做主旨大意题。
3、重点敲定主旨题。主旨大意题提问的形式主要有两大类:一类是Main idea型;一类是Topic或Title型。
在解答这类试题时应注意以下几点:
a.读首句抓大意。
文化教育类阅读理解文章多采用说明文、议论文体裁,而这类文章大都采用文章段落的中心,即主题句在文章开头。因此,要寻找这类文章的主旨大意就需要研究文章的首句。
b.读尾句抓大意。
有时这类文章的主题句安排在文章的结尾,作为对全篇的总结。
c.读首段抓大意。
有些文章或段落的开头和结尾部分都有主题句。这种结构是为了突出主题思想而使用两次点题的写作方法。这两个主题句在句子结构和用词上有所不同,而且在内容上前句和后句也不重复。
d.从段落中抓大意。
有些文章或段落的主题句在文章中,这种文章或段落往往以一句话或几句话引出要表达的主题,在主题句出现后,再举例子陈述细节或继续论证。
e.归纳要点抓大意。
有些文章或段落无明显的主题句,只是暗示性地体现主题。这就要求同学们在阅读过程中根据文中所叙述的事实或线索来概括总结主旨大意。
