伟大的喜剧艺术从不以彼岸世界为其目标，它所追求的并不是要予人以神秘玄惑感，它并不会通过将任何与善不一样的事物烙上罪恶的印记而否认那些模棱两可的情形。伟大的喜剧艺术家们认为，真理可呈现出各种不同的表现形态，故而他们力图强调社会行为中的对立矛盾，而不是通过诉诸于那些代表着神圣目标、字宙目的、或自然法则的超社会象片符号去掩饰或超越它们。伟大的喜剧艺术中的超越瞬间乃是一个社会性瞬间，源自这样一个坚定信念，即我们终是凡夫俗子，尽管我们竭力想成为神灵。艺术家们所致力表现的那个不乏喜剧色彩的社会，是一个由那些具有理性思维能力、充满爱心、快乐、和富于怜悯之心的人类构成的社会，他们甘愿承担人类理性行动的风险。伟大的喜剧艺术根本不祈求神灵或魔鬼，相反，它激发起我们对于理性的无畏勇气，这种勇气缘自对人类作为人所能做到的一切的信心。

答案：(C)
It has long been known that the SE,－
rate of oxidative metabolism (the o-m
process that uses oxygen to convert for
into energy) in any animal has a
(5) profound effect on its living patterns.
The high metabolic rate of small
animals, for example, gives them
sustained power and activity per unit of
weight, but at the cost of requiring
(10) constant consumption of food and water.
Very large animals, with their
relatively low metabolic rates, can
survive well on a sporadic food supply,
but can generate little metabolic energy
(15) per gram of body weight. If only SE，∨
oxidative metabolic rate is considered,
therefore, one might assume that
smaller, more active, animals could
prey on larger ones, at least if they
(20) attacked in groups. Perhaps they could SE
if it were not for anaerobic glycolysis, a-g
the great equalizer. +
Anaerobic glcolysis is a process in TS
which energy is produced, without
(25) oxygen, through the breakdown of muscle
glycogen into lactic acid and adenosine ATP
tri-phosphate (ATP), the energy
provider. The amount of energy that can
be produced anaerobically is a function
(30) of the amount of glycogen present-in all 0.5%
vertebrates about 0.5 percent of their
muscles' wet weight. Thus the anaerobic
energy reserves of a vertebrate are
proportional to the size of the animal.
(35) If, for example, some predators had
attacked a 100-ton dinosaur, normally
torpid, the dinosaur would have been
able to generate almost instantaneously,
via anaerobic glycolysis, the energy of
(40) 3,000 humans at maximum oxidative
metabolic energy production.This SE
explains how many large species have
managed to compete with their more
active neighbor: the compensation for
(45) a low oxidative metabolic rate is
glycolysis.
There are limitations, however, to this SE, ∨
compensation. The glycogen reserves
of any animal are good, at most, for
(50) only about two minutes at maximum ∨
effort, after which only the normal
oxidative metabolic source of energy
remains. With the conclusion of a burst
of activity, the lactic acid level is
(55) high in the body fluids, leaving the
large animal vulnerable to attack until
the acid is reconverted, via oxidative
metabolism, by the liver into glucose,
which is then sent (in part) back to the
(60) muscles for glycogen resynthesis. During
this process the enormous energy debt
that the animal has run up through
anaerobic glycolysis must be repaid, a
debt that is proportionally much greater ＞
(65) for the larger vertebrates than for the
smaller ones. Whereas the tiny shrew can ﹥﹤
replace in minutes the glycogen used
for maximum effort, for example, the
gigantic dinosaur would have required
(70) more than three weeks. It might seem
that this interminably long recovery
time in a large vertebrate would prove
a grave disadvantage for survival.
Fortunately, muscle glycogen is used +
(75) only when needed and even then only in ⊙
whatever quantity is necessary. Only in ⊙
times of panic or during mortal combat
would the entire reserves be consumed.
科学家长期以来已知，氧化新陈代射（oxidative metabolism，亦即使用氧气将食物转化为能量的过程）的速度，在任何动物身上，会对其生存方式产生重大的影响。例如，小动物较高的新陈代谢率，以其体重的每单位计算均能赋予动物以持续不断的能量和活动能力，但其代价是，要求它们不间断地消耗水和食物。而大动物，以其相对低的新陈代谢率，仅凭着不规则的食物供应即可安然无恙，但以体重的每一克来计算，几乎不能产生任何新陈代谢能量。倘若仅仅考虑氧化新陈代谢速度的话，人们或许会假设，那些较小的、较为活跃的动物可以捕食较大的动物，至少是如果它们成群结队发起攻击的话。或许它们能做到这一点，假若不是因为无氧糖酵解（anaerobic glycolysis）这一举足轻重的均衡因素的话。
无氧糖酵解指的是这样一个能量产生的过程：在没有氧气的情况下，通过将肌肉糖原（muscle glycogen）分解成为乳酸（lactic acid）和三磷酸腺苷（adenosinetriphosphate，简称ATP），一种提供能量的物质。以无氧方式（anaerobically）产生的能量的数量，是所存在的糖原数量的一个函数——在所有脊椎动物（vertebrate）身上，大约是其肌肉湿重的0.5%。因此，一头脊椎动物的无氧能量储备是与该动物的尺寸大小成正比的。例如，如果某些食肉动物向一头100吨重的恐龙——一般表现得迟缓呆钝——发起攻击的话，这头恐龙极有可能几乎在瞬间内，通过无氧糖酵解，产生出相当于3000个人在最大程度上氧化新陈代谢能量产生过程中所产生的能量。这足以解释许多庞大的动物种类如何得以成功地与它们那些更为活跃的“邻居”相竞争抗衡的：对于较低的氧化新陈代谢率，动物的补偿机制就是糖酵解。
然而，这种补偿机制也不乏缺陷。任何动物的糖原储备在全力以赴的搏斗中最多只能维持两分钟的有效时间，在此之后，仅剩下通常的氧化新陈代谢能量来源。随着一阵剧烈活动的终结，体液（body fluid）中的乳酸含量极高，致使大动物陷入一种易受攻击的状态，直到乳酸通过氧化新陈代谢过程，由肝脏重新转化成葡萄糖（glucose），这些葡萄糖随后——部分地——被传送回肌肉进行糖原的再合成（glycogenresynthesis）。在此过程中，动物通过无氧糖酵解迅速积累起来的巨大的能量缺失（energy debt）必须予以弥补，从比例上看，这种能量的缺失对于较大的脊椎动物要远甚于较小的脊椎动物。例如，虽则体小的 仅在几分钟之内就能补充殊死搏斗中所消耗的糖原，而庞然大物恐龙却需要三个多星期的时间。这似乎会让人觉得，大脊椎动物身上这种没完没了的漫长复原期将对其生存构成一严重不利的影响。值得庆幸的是，肌肉糖原只是在必需的时候才会被使用，而即使在这些时候也只是按必要的数量来使用。唯有在惊慌失措之际，或在生死攸关的撕杀中，全部的糖原储备才会被彻底耗竭。
