多样性(diversity)、中国人(chinese)、物理量(physical quantity)、甲骨文、特征描述(feature description)、根本原因(basic reason)、使用时间(hour of use)、磁感应强度(magnetic induction)、书法家(calligrapher)、头状花序(head)
[单选题]下列理解和分析,不符合原文内容的一项是
A. 在字形的繁难复杂方面,秦隶和汉隶要超过真书,甲骨文又要超过秦隶和汉隶,可以说这是真书使用时间(hour of use)特别长久的根本原因。
B. 古时候书法流派不多,当时甚至没有“书法家(calligrapher)”这一称呼,而到唐代书法大盛,流派逐渐增多,看来书法的发展跟社会的崇尚有很大的关系。
C. 中国人自古就把书法作为人的品格和形象的代表,所以北朝人所谓“尺牍素书,千里面目”,也就是今人所谓“见字如见其人”的意思。
D. 在唐代有些无名书法家(calligrapher)的水平也很高,唐人碑版的书法其实并不代表当时的最高水平,只是因为它们是皇帝、大官所写,才为世人所推崇。

[单选题](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.
A. 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.
B. 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.
C. "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.
D. 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.
E. 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.
F. 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.
G. 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.
H. 72. The phrase "communications blackout" in paragraph 1 most probably refers to during the 2012 Olympics.
I. the extinguishing of the Olympic torch
J. the collapse of broadcasting systems
K. the transportation breakdown in London
L. the destruction of weather satellites
