    Jeanne Calment took up skating at age 85, made her first movie appearance at age 114, and held a concert
    in the neighborhood on her 121st birthday.
    When it comes to long life, Jeanne Calment is the world' s recordholder. She lived to the ripe old age of
    122. So is 122 the upper limit (限制) to the human life span (寿命)? If scientists come up with some sort of
    pill or diet that would slow aging, could we possibly make it to 150-or beyond?
    Researchers don't entirely agree on the answers."Calment lived to 122, so it wouldn't surprise me if
    someone alive today reaches 130 or 135," says Jerry Shay at the University of Texas.
    Steve Austad at the University of Texas agrees. "People can live longer than we think," he says. "Experts
    used to say that humans couldn't live past 110. When Calment blew past that age, they raised the number to
    120. So why can't we go higher?"
    The trouble with guessing how old people can live to be is that it' s all just guessing."Anyone can make up
    a number," says Rich Miller at the University of Michigan. " Usually the scientist who picks the highest number
    gets his name in Time magazine.
    Won't new anti-aging techniques keep us alive for centuries? Any cure, says Miller, for aging would
    probably keep most of us living until about 120. Researchers are working on treatments that make the life
    span of mice longer by 50 percent at most. So, if the average (平均) human life span is about 80 years, says
    Miller, " adding another 50 percent would get you to 120."
    So what can we leam from this little disagreement among the researchers? That life span is flexible (有弹
    性的), but there is a limit, says George Martin of the University of Washington. "We can get flies to live 50
    percent longer," he says. " But a fly's never going to live 150 years." Of course, if you became a new species
    (物种), one that ages at a slower speed, that would be a different story, he adds.
    Does Martin really believe that humans could evolve (进化) their way to longer life?"It' s pretty cool to
    think about." He says with a smile.
    1. What does the story of Jeanne Calment prove to us?
    A. People can live to 122.
    B. Old people are creative.
    C. Women are sporty at 85.
    D. Women live longer than men.
    2. According to Steve Austad at the University of Texas, ________.
    A. the average human life span could be 110
    B. scientists cannot find ways to slow aging
    C. few people can expect to live to over 150
    D. experts aren't sure how long one can live
    3. Who thinks that a scientist will become famous if he makes the wildest guess at longevity?
    A. Jerry Shay.
    B. Steve Austad.
    C. Rich Miller.
    D. Ceorge Martin.
    4. What can we infer from the last three paragraphs?
    A. Most of us could be good at sports even at 120.
    B. The average human life span cannot be doubled.
    C. Scientists believe mice are aging at a slower speed than before.
    D. New techniques could be used to change flies into a new species.

健康环保类阅读

等考点的理解。关于这些考点您可以点击下面的选项卡查看详细档案。
  • 健康环保类阅读
健康环保类阅读:
本类型主要是围绕饮食健康、医疗卫生及环境保护等方面选取实际的材料来设题。
体裁有记叙文、说明文、议论文和各种应用文。
健康环保类阅读题答题注意事项和技巧:
应试生态环保类题目时,在理解文章的基础上,要重点突破——归纳主旨大意技能,因为推断是以整体理解为基础的推断能力。
1.归纳主旨大意:
(1)寻找具体段落的中心思想的方法是:找出每小段的主题句。
主题句通常有这样的特点:
①有一个话题(topic);
②有阐述控制性概念,偶尔也可在一段中间;
③有的文章无明显主题句,主题句隐含在段意之中。这就需要读者进一步加工概括了。
(2)寻找整篇文章的中心思想的方法建立在寻找具体段落中心的基础上的。
应观察全文的结构安排,理解文章浓墨重笔写的“重心”,考虑文章组织材料及支撑性细节是服务于什么的,分析故事的发展结局都是围绕什么中心大意来安排的。
(3)典型错误:
①忽视文章的结构;
②混淆了中心与支撑细节或材料的区别;
③忽视文章表意的倾向性;
④漏掉了主要的特征词。

2.正确推理判断:
推理判断试题要求考生尽量考虑文中全部信息或事实,在通篇理解文章的基础上领会作者的言外之意,并作出正确的推理和判断。
(1)数据推断题
解答此类题,关键是要善于捕捉有关数字的信息,然后在透彻理解原文的字面意义和题意的基础上,运用自己的数学知识,对其进行分析、推算,从而得出正确的结论。
(2)知识推断题
根据文章中所阐述的细节,运用基础知识进行分析、推敲,从而得出符合文章原义的结论的一种推断方法。
(3)逻辑结论推断题
根据事实、论点、例证等一系列论据材料,不是根据自己的经验、态度、观点或爱好去理解文章的内涵。
解答这类题的前提是要首先获得短文的主题思想或列举的具体事实,然后按题意要求进行推断。
(4)对作者态度、倾向的推断题
作者的倾向和感情往往隐含在文章的字里行间,或流露于修饰的词语之中,因此,在推断过程中,应特别注意文中作者的措辞。
