预测地震,云不会说谎

    ①1976年唐山大地震前夜,昌黎县几个看瓜地的人被巨光吓得惊惶失措。阴沉的夜空就像忽然有人打开了它的开关,巨大的亮光照亮了一切,连西瓜叶、瓜蔓都看得清清楚楚。光亮瞬间消失,夜空复又变暗,如墨染一般。同天傍晚,日本的真锅大觉教授发现天空有异常长条云,后来证实,那就是唐山地震的前兆云。

    ②日本是地震大国,这方面的记载也比比皆是。1948年6月27日,日本奈良市上空出现了一条异常带状云。第三天,日本福井就发生了7.3级大地震。……

    ③这些地震前出现的怪云,我们称之为地震云。历次地震中,它们都以不同的面孔,在不同的地区或早或晚地出现,向人类传递着来自大自然的信息预警。

    ④地震云和普通云有很大的区别。地震云外形很怪异,具有非常鲜明的特征:一是横条状出现,一条一条在空中有序排列,且每一条的颜色都深浅分明,就像我们经常在天空中看到的飞机尾烟。如果天空中有这样的云,预示着两周后会有地震;二是多条,成平行或者放射状出现,人们形象地称之为排骨云,平行状云表示地震会出现在本地,放射状云预示着2~6天后有地震;第三种地震云看起来就像垂直的龙卷风挂在空中,有时又像无风时垂直上升的烟柱,这样的云叫做卷震云,预示着地震将发生在3天后;第四种是鱼鳞或团状地震云,云团在数小时内形成松散鱼鳞状,有时和“条状地震云”同时出现,颜色深浅分明,这表示2~6天以后会发生地震。

    ⑤这些模样怪诞的地震云,其长度和颜色也隐藏着诸多密码:比如地震云长度越长预示着离发生地震的时间越近;地震云颜色越深,表示对应的地震深度就越深;地震云持续的时间长,预示对应的震中就越近;如果地震云又粗又厚并且呈现出灰色,那么地震的破坏力将会很大。

    ⑥研究者发现,不管哪种地震云,它们出现时都与周边云彩格格不入,有明显界限。地震云还很高傲,喜欢朦胧,一般都是在早晨和傍晚时分出现在6000米高空,比气象云高出许多;地震云变幻无常,通常有白色、灰色、橙色和橘红色之分,有时它自身会发出强烈的光芒;地震云不怕风,无论风刮得多么猖狂,它们始终不会变形。

    ⑦关于地震云的成因有两种说法,一是热量学说。地震前,地震带周围聚集了大量地热,或者地震带周围的岩石受强烈地应力作用,激烈摩擦后产生大量热量。这些热量从地表逸出后,温度骤然增高,产生的气流飘到高空,就形成了地震云;二是电磁说。地震前,岩石在地应力作用下出现“压磁效应”,地磁场跟着变化。岩石在地应力作用下发生变形,引起电阻率变化,使电磁场也跟着产生变化。由于电磁波影响到高空电离层,电离层电浆浓度锐减,这时水汽和尘埃就会有序排列,形成地震云。

    ⑧虽然现在人类还无法准确预测地震,我们对地震云的研究也还不成熟,但地震云提醒我们:只要做好相关数据的收集和分析,地震云必将会为地震预报提供翔实依据和有力参考。因为,云从来不说谎。

       Technological change is everywhere and affects every aspect of life, mostly for the better. However, social changes are brought about by new technology are often mistaken for a change in attitudes.

       An example at hand is the involvement of parents in the lives of their children who are attending college. Surveys (调查) on this topic
 suggests that parents today continue to be “very” or“somewhat” overlyprotective even after their children move into college
dormitories. The same surveys also indicate that the rate of parental involvement is greater today than it was a    generation ago.This is usually  interpreted as a sign that today’s  parents are trying to manage  their children’s lives past the point where this behavior is appropriate.
       However, greater parental involvement does not necessarily indicate that parents are failing to let go of their “adult” children.
In the context (背景) of this discussion, it seems valuable to first find out the cause of change in the case of parents’ involvement with
 their grown children.If parents of earlier generations had wanted to be in touch with their college-age children frequently, would this 
have been possible? Probably not. On the other hand, does the possibility of frequent communication today mean that the urge to do so wasn’t present a generation ago? Many studies show that older parents - today’s grandparents - wouldhave called their children more often if the means and cost of doing so had not been a barrier.
        Furthermore, studies show that finances are the most frequent subject of communication between parents and their college children. The fact that college students are financially dependent on their parents is nothing new; nor are requests for more money to be sent from
 home. This phenomenon is neither good nor bad; it is a fact of college life,today and in the past.
        Thanks to the advanced technology, we live in an age of bettered communication. This has many implications well beyondthe role that parents seem to play in the lives of their children who have left for college.But it is useful to bear in mind that all such changes come from the technology and not some imagined desire by
 parents to keep their children under their wings.
