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
【C4】
选项
答案
G
解析
空格前为副词directly,空格后为介词in,故本空需要填入一个动词。本句是一个省略结构,完整的句子应该是whether central fatigue might also affect motor systems which are not directly ______ in the exercise itself。结合句意可知,人运动时,许多运动系统没有直接参与到其中。备选项中只有involved(使参加)符合句意,故答案为G。
