概括下面这段文字的主要内容。（不超过25字）（3分）
对于五四时期的新文学阵营而言，所谓“新”，代表着晚近的先进的事物，代表着现在和未来的发展方向，而“旧”则是落后的腐朽的事物，是应该抛弃和埋葬的，可是在旧文学阵营的眼中，所谓“新”，只是新潮的、还未经过时间考验的东西，往往昙花一现，其中有太多需要去掉的夸饰和虚伪，而“旧”则是经过历史检验的真理，是过去的精华所在。
(C)
The 2012 London Olympics had enough problems to worry about. But one more has just been added - a communications blackout caused by solar storms.
After a period of calm within the Sun, scientists have detected the signs of a flesh cycle of sunspots that could peak in 2012, just in time for the arrival of the Olympic torch in London.
Now scientists believe that this peak could result in vast solar explosions that could throw billions of tons of charged matter towards the Earth, causing strong solar storms that could jam the telecommunications satellites and interact links sending five Olympic broadcast from London.
"The Sun's activity has a strong influence on the Earth. The Olympics could be in the middle of the next solar maximum which could affect the functions of communications satellites," said Professor Richard Harrison, head of space physics at the Rutherford Appleton Laboratory in Oxfordshire.
At the peak of the cycle, violent outbursts called coronal mass ejections (日冕物质抛射) occur in the Sun's atmosphere, throwing out great quantities of electrically-charged matter. " A coronal mass ejection can carry a billion tons of solar material into space at over a million kilometres per hour. Such events can expose astronauts to a deadly amount, can disable satellites, cause power failures on Earth and disturb communications," Professor Harrison added. The risk is greatest during a solar maximum when there is the greatest number of sunspots.
Next week in America, NASA is scheduled to launch a satellite for monitoring solar activity called the Solar Dynamics Observatory (SDO), which will take images of the Sun that are 10 times clearer than the most advanced televisions available.
The Rutherford Appleton Laboratory helped to make the high-tech cameras that will capture images of the solar flares (太阳耀斑) and explosions as they occur.
Professor Richard Hold away, the lab's director, said that the SDO should be able to provide early warning of a solar flare or explosion big enough to affect satellite communications on Earth "If we have advance warning, we'll be able to reduce the damage. What you don't want is things switching off for a week with no idea of what's caused the problem," he said.
72. The phrase "communications blackout" in paragraph 1 most probably refers to during the 2012 Olympics.
A. the extinguishing of the Olympic torch
B. the collapse of broadcasting systems
C. the transportation breakdown in London
D. the destruction of weather satellites
A. alongB. aroundC. byD. in
下列有关债券的说法中，正确的是()。
A．当必要报酬率高于票面利率时，债券价值高于债券面值
B．在必要报酬率保持不变的情况下，对于连续支付利息的债券而言，随着到期日的临近，债券价值表现为一条直线，最终等于债券面值
C．当必要报酬率等于票面利率时，随着到期时间的缩短，债券价值一直等于债券面值
D．溢价出售的债券，利息支付频率越快，价值越低
艺术和科学的共同基础是人类的创造力，它们追求的目标都包含着某种普遍性。
艺术，列入诗歌、绘画、音乐等，用创新的手法去唤起每个人的意识或潜意识中生藏着的、已经存在的情感。如李白在《把酒问月》中写道：“青天有月来几时？我今停杯一问之………今人不见古时月，今月曾经照古人。古人今人若流水，共看明月皆如此。”而三百多年后，苏轼作了《水调歌头》：：明月几时有？把酒问青天……人有悲欢离合，月有阴晴圆缺，此事古难全。但愿人长久，千里共婵娟。”在咏诵这些诗的时候，它们的相似之点和不同之处同样感动着读者。尽管李白、苏轼生活的时代和今天的社会已经完全不同了，但这些几百年乃至一千年前的诗歌在今天人们的心中仍然能够引发强烈的感情共鸣。
同样，我们现在阅读莎士比亚的著作，或者观赏莎士比亚的戏剧，不论是原文或译文，也有着和几百年前英国的读者观众相似的情感共鸣。情感越珍贵，反响越普遍，跨越时空、社会的范围越广泛，艺术就越优秀。
科学，例如天文学、物理学、化学、生物学等，对自然界的现象进行新的准确的抽象，这种抽象通常被称为自然规律。定律的阐述越简单、应用越广泛，科学就越深刻。尽管自然现象不依赖于科学家而存在，但对自然现象的抽象和总结却属于人类智慧的结晶，这和艺术家的创造是一样的。
在科学中，人们研究物质的结构，知道所有物质都是由分子、原子构成，原子又都由原子核和电子构成，原子核又由质子、中子组成，质子、中子又由夸克组成等。人们认识了物质的基本结构，进而去认识世界和宇宙。
科学技术的应用形式会不断的发生新的变化，但其科学原理并不随这些应用而改变，这就是科学的普遍性。
在19世纪和20世纪之交，科学上有两个关键性的发现，它们看上去似乎有些神秘，与我们的日常生活无关。一个是迈克耳孙和莫雷在1887年做的光速实验，另一个是普朗克在1900年发现的黑体辐射公式。前者是爱因斯坦狭义的相对论的实验依据，后者为量子力学奠定了基础。正是有了相对论和量子力学，20世纪的科技发展，如核能、原子物理、分子束、激光、X射线技术、半导体、超导体、超级计算机等，才得以存在。因此，科学原理应用越广泛，在人们社会生活中的表现形式也越多样化。
