题型介绍
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 1 them again. During 26 exercise, our muscles tire as they run out of fuel and build up waste products.
好像你还需要其他理由痛恨健身馆似的，现在证明锻炼不仅使肌肉感到疲劳，还会让眼睛困倦。但是不用害怕，因为咖啡能使它们重新恢复活力。在 (26) 剧烈运动时，随着能量耗尽、废物积累，我们的肌肉会感到疲劳。
Muscle performance can also be affected 2 by a 27 called "central fatigue 3," in which an imbalance in the body's chemical messengers prevents the central nervous system from directing muscle movements 28 . It was not known, however, whether central fatigue might also affect motor systems not directly 29 in the exercise itself, such as those that move the eyes.
肌肉的性能也受被称之为“中央疲倦” (27) 现象的影响，即身体中传递化学物质的信使不均衡，导致中央神经系统不能 (28) 有效地指导肌肉运动。但是，之前人们并不知道中央疲倦是否可能影响未直接 (29) 参与锻炼的运动肌肉系统，例如那些使眼睛活动的肌肉。
To find out, researchers gave 11 volunteer cyclists a carbohydrate 4 (碳水化合物的) 30 either with a moderate dose of caffeine (咖啡因), which is known to stimulate the central nervous system, or as a placebo 5 (安慰剂) without, during 3 hours of 31 . After exercising, the scientists tested the cyclists with eye-tracking cameras to see how well their brains could still 32 their visual system.
为了查明这一点，在3小时的 (31) 骑行中，研究人员给11名自行车手志愿者一支碳水化合物 (30) 溶剂，有的含有适量的咖啡因，能够刺激中央神经系统；有的是作为安慰剂，不含咖啡因。在锻炼后，科学家用追踪眼动的摄像机检测这些车手，以发现他们的大脑对视觉系统 (32) 控制如何。
The team found that exercise reduced the speed of rapid eye movements by about 8%, 33 their ability to capture new visual information. The caffeine, the equivalent of two strong cups of coffee, was 34 to reverse this effect, with some cyclists even displaying 35 eye movement speeds. So it might be a good idea to get someone else to drive you home after that marathon.
研究团队发现，锻炼大约降低了快速眼动速度的8%，从而 (33) 妨碍了眼睛捕捉新的视觉信息的能力。溶剂中的咖啡因相当于两杯浓咖啡，(34) 足以扭转这一影响，有的自行车手眼动速度甚至 (35) 加快了。因此，跑完马拉松后，找人开车送你回家也许是个好主意。
