As if you needed another reason to hate the gym, it now turns out that exercise can exhaust not only your muscles, but also your eyes. Fear not, however, for coffee can stimulate them again. During【C1】______ exercise, our muscles tire as they run out of fuel and build up waste products. Muscle performance can also be affected by a【C2】______ called " central fatigue" , in which an imbalance in the body’s chemical messengers prevents the central nervous system from directing muscle movements【C3】______ It was not known, however, whether central fatigue might also affect motor systems not directly【C4】______ in the exercise itself, such as those that move the eyes. To find out, researchers gave 11 volunteer cyclists a carbohydrate {碳水化合物)【C5】______ either with a moderate dose of caffeine (咖啡因) , which is known to stimulate the central nervous system, or as a placebo (安慰剂) without, during 3 hours of【C6】______ After exercising, the scientists tested the cyclists with eye-tracking cameras to see how well their brains could still【C7】______ their visual system. The team found that exercise reduced the speed of rapid eye movements by about 8% ,【C8】______ their ability to capture new visual information. The caffeine, the equivalent of two strong cups of coffee, was【C9】______ to reverse this effect, with some cyclists even displaying【C10】______ eye movement speeds. So it might be a good idea to get someone else to drive you home after that marathon.
A) cautiously I) phenomenon
B) commit J) preventing
C) control K) sensitive
D) cycling L) slowing
E) effectively M) solution
F) increased N) sufficient
G) involved O) vigorous H) limited
【C8】
选项
答案
J
解析
空格前为完整的句子The team found that exercise reduced the speed of rapid eye movements by about 8%(研究团队发现运动使得眼球快速移动的速度下降了8%),而空格后为名词加不定式。又结合句意可知,眼球快速移动的速度下降,应该是不利于眼睛捕捉新的视觉信息,故空格处应填入一个现在分词,表示主句的动作造成的结果。备选项中只有preventing(防止,阻止)符合句意,故答案为J。
