图4中,虚线ACB表示晨昏线,BC为晨线,阴影部分表示7月6日。据此回答:

小题1:下列叙述正确的是

①该图表示北半球 ②该图表示南半球

③非阴影部分为7月5日 ④非阴影部分为7月7日

A.①④

B.②③

C.①③

D.②④小题2:此时北京时间为

A.7月6日12时

B.7月7日12时

C.7月6日24时

D.7月5日24时

答案

小题1:D

小题2:B

考查太阳光照图的综合判读。

小题1:根据BC为晨线看判断,P点可能为0时或12时,但是根据阴影部分表示7月6日,可以判断,P点只能是0时。因此该图右半部分应该为黑夜,左半部分为白天。所以该图表示南半球,非阴影部分为7月7日。

小题2:根据前一小题,可判断N点为180°,根据自转和时间计算,北京时间为7月7日12时。

Education is one of the key words of our time. A man, without an education, many of us believe, is an unfortunate victim of unfortunate circumstances deprived of one of the greatest twentieth-century opportunities. Convinced of the importance of education, modern states "invest" in institutions of learning to get back "interest" in the form of a large group of enlightened young men and women who are potential leaders. Education, with its cycles of instruction so carefully worked out, is punctuated by textbooks--those purchasable wells of wisdom what would civilization be like without its benefits

So much is certain: that we would have doctors and preachers, lawyers and defendants, marriages and births; but our spiritual outlook would be different. We would lay less stress on "facts and figures" and more on a good memory, on applied psychology, and on the capacity of a man to get along with his fellow-citizens. If our educational system were fashioned after its bookless past we would have the most democratic form of "college" imaginable. Among the people whom we like to call savages all knowledge inherited by tradition is shared by all; it is taught to every member of the tribe so that in this respect everybody is equally equipped for life.

It is the ideal condition of the "equal start" which only our most progressive forms of modern education try to reach again. In primitive cultures the obligation to seek and to receive the traditional instruction is binding on all. There are no "illiterates"--if the term can be applied to peoples without a script--while our own compulsory school attendance became law in Germany in 1642, in France in 1806, and in England in 1976, and is still non-existent in a number of "civilized" nations. This shows how long it was before we considered it necessary to make sure that all our children could share in the knowledge accumulated by the "happy few" during the past centuries. Education in the wilderness is not a matter of monetary means. All are entitled to an equal start. There is none of the hurry that, in our society, often hampers the fui1 development of a growing personality. There, a child grows up under the ever-present attention of his parents; therefore the jungles and the savages know of no "juvenile delinquency". No necessity of making a living away from home results in neglect of children, and no father is confronted with his inability to ’"buy" an education for his child.

A. The Significance of Education

B. Educational Investment and Its Profit

C. Education and Modern Civilization

D. Education: A Comparison of Its Past and Its Present

据人民网转载《江南时报》报道,关于第三只眼的说法由来已久,在东方的许多宗教仪式上,人们习惯在双眉之间画上第三只眼,认为这样便可获得与宇宙进行直接交流的通道。古希腊哲学家认为,第三只眼位于大脑中心部位,将其比喻为宇宙能量进入人体的闸门。直至今日,现代医学对第三只眼的研究也从未停止过。不久前,俄罗斯《总结》周刊的一篇文章对“第三只眼”作了详尽报道。古人类学家别洛夫认为,这一器官退化痕迹残留在大脑半球下。“退化的眼睛”与松果体类似,是一个不大的非对称器官。
第三只眼出现在胚胎发育两个月时,即晶体、感光器和间脑区域的神经细胞形成阶段。奇怪的是,它刚一出现,马上就开始退化。著名的海克尔生物基因定律为此提供了最有力的证据。根据这一定律,胚胎在很短的时期内会经历其所属物种的整个进化史。即人类在胚胎时期能够出现我们的先祖所具备的某些形态特征。人类学家认为,人体的某个器官会发生退化,然后便不复存在。从古代两栖动物的进化中可以发现它们同样伴有退化。新西兰的斑点楔齿蜥已经存在了2亿年,它的颅骨上有很小的眼眶,在一层透明的膜下隐藏着一只真正的眼睛。古生物学家发现,许多灭绝的爬行动物头顶都有眼睛,它是这些动物视觉器官的重要补充。正是因为具有这一独特的器官,爬行动物才对地震、磁暴和火山爆发等自然灾害非常敏感。动物的第三只眼确实能够物尽其用,而且还可以保护自身安全,但人要它来做什么呢
别洛夫认为,先知者眼前出现的画面,正是松果体作用的结果。大脑将宇宙中的能量汇集起来,而身体与地面振荡保持一致。所以,松果体能够从宇宙获得超凡的想象力,将其化作神经冲动,到达丘脑下部。然后,这些信号随着神经进入视网膜,视网膜上便出现虚拟的图像,同时,图像以神经冲动的形式继续传入大脑的视觉皮层,产生意识。未卜先知的画面通常是闭眼而非睁眼时出现的。未卜先知的能力应该是在我们的祖先失去了头顶上的眼睛后,作为对这一消失器官的补偿而出现的。
别洛夫认为,祭司充分利用了这一退化器官。为发挥第三只眼的功能,他们用钻石做头饰,在宗教仪式时佩戴。或许,宇宙的神秘能量正是通过宝石透明剔透的结构,以光束的形式汇聚到头顶。电磁波到达松果体并作用于其组织,水晶起的作用与晶体类似,只是它吸收的并非普通光线,而是宇宙能量。在宗教仪式上,祭司正是借助人为的第三只眼,洞悉一切。
在旧石器时代末期,一些宗教学说的信徒通常会被施以脑颅环锯术,他们的头顶会被挖出不同形状的洞。环锯术的被施予者都是祭司的候选人,不知这是不是为了减轻宇宙神秘能量进入松果体的难度。松果体是否是第三只眼睛,它是否具有特殊功能目前尚无定论。
圣彼得堡的生物学专家对松果体进行了研究。他们发现这种神秘腺体在性成熟前发挥着重要的作用,随后它的作用形式发生了变化。因此学术界一直认为,它跟阑尾一样毫无用处。但俄罗斯学者发现它在不同时期都发挥着积极作用。其组成细胞类似视网膜的色素细胞,有能够分泌激发肌体活性的血清素和具有镇静作用的褪黑激素,两者的分泌量也是相当恒定的。人到了另一个时区作息会失调,身体机能会发生暂时紊乱,正是松果体在捣乱。
古代曾经有能量中心之说,这一中心很早就被冠以第三只眼之名,因为它能够接收和反映出具体的图像,看来古人的结论不无道理。
(邵月明《人类第三只眼确实存在》)

从作者的若干结论中找出本文的中心是:

A.古代的能量中心之说被冠以第三只眼之名有道理。
B.人类可以获得与宇宙进行直接交流的通道。
C.动物的第三只眼确实能够保护自身安全物尽其用。
D.松果体、第三只眼、特殊功能关系目前尚无定论。
