4、项A.mistakeB.faultC.disadvantageD.defect【答案】C【解析】考查固定搭配。be at a disadvantage “处于不利的地位”。选项C符合题意。5. 单选题It has long been known that the rate of oxidative metabolism (the process that uses oxygen to convert food into energy) in any animal has a profound effect on its living patterns. The high metabolic r
5、ate of small animals, for example, gives them sustained power and activity per unit of weight, but at the cost of requiring 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 metab
6、olic energy per gram of body weight. If only oxidative metabolic rate is considered, therefore, one might assume that smaller, more active, animals could prey on larger ones, at least if they attacked in groups. Perhaps they could if it were not for anaerobic glycolysis, the great equalizer.Anaerobi
7、c glycolysis is a process in which energy is produced, without oxygen, through the breakdown of muscle glycogen into lactic acid and adenosine triphosphate (ATP), the energy provider. The amount of energy that can be produced anaerobically is a function of the amount of glycogen present in all verte
8、brates about 0.5 percent of their muscles net weight. Thus the anaerobic energy reserves of a vertebrate are proportional to the size of the animal. If, for example, some predators had attacked a 100-ten dinosaur, normally torpid, the dinosaur would have been able to generate almost instantaneously,
9、 via anaerobic glycolysis, the energy of 3,000 humans at maximum oxidative metabolic energy production. This explains how many large species have managed to compete with their more active neighbors: the compensation for a low oxidative metabolic rate is glycolysis.There are limitations, however, to
10、this compensation. The glycogen reserves of any animal are good, at most, for 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 high in the body fluids, leaving the
11、large animal vulnerable toattack until the acid is reconverted, via oxidative metabolism, by the liver into glucose, which is then sent (in part) back to the muscles for glycogen resynthesis. During this process the enormous energy debt that the animal has run up through anaerobic glycolysis must be
12、 repaid, a debt that is proportionally much greater 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 more than three weeks. It might seem that this intermin
13、ably long recovery time in a large vertebrate would prove a grave disadvantage for survival. Fortunately, muscle glycogen is used 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.1.The primary
14、purpose of the passage is to（ ） .2.According to the author, a major limitation of anaerobic glycolysis is that it can（ ） .3.The passage suggests that the total anaerobic energy reserves of a vertebrate are proportional to the vertebrates size because（ ） .4.The author is most probably addressing whic
15、h of the following audiences?5.Which of the following best states the central idea of the passage?问题1选项A.refute a misconception about anaerobic glycolysisB.explain anaerobic glycolysis and its effects on animal survivalC.describe the limitations of anaerobic glycolysisD.analyze the chemistry of anaerobic glycolysis and its similarity to oxidative metabolism问题2选项A.produce in large animals more lactic acid than the liver can safely reconvertB.necessitate a dangerously long recovery period in large animalsC.produce energy more slowly than it can
