Fear not, however, for coffee can perk them right up again. During 26 exercise, our muscles tire as they run out of fuel and build up waste products. Muscle performance can also be affected by a 27 called “central fatigue,” in which an imbalance in the bodys 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 itselfsuch as those that move the eyes. To find out, researchers gave 11 volunteers a carbohydrate 30 either with a moderate dose of caffeinewhich is known to stimulate the central nervous systemor as a placebo 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. The team found that exercise reduced the speed of rapid eye movements by about 8%, 33 their ability to capture new visual information. The caffeinethe equivalent of two strong cups of coffeewas 34 to counteract this effect, with some cyclists even displaying 35 eye movement speeds, the team reports today in Scientific Reports. So it might be a good idea to get someone else to drive you home after that marathon.A) cautiouslyB) commitC) controlD) cyclingE) effectivelyF) increasedG) involvedH) limitedI) phenomenonJ) preventingK) sensitiveL) slowingM) solution N) sufficientO) vigorousSection BDirections: In this section, you are going to read a passage with ten statements attached to it.

As much as we would like to cling on to our past, even the saddest moments can be washed away with time.B Ask Nima Veiseh what he was doing for any day in the past 15 years, however, and he will give you the details of the weather, what he was wearing, or even what side of the train he was sitting on his journey to work. “My memory is like a library of video tapes, walk-throughs of every day of my life from walking to sleeping,” he explains.C Veiseh can even put a date on when those tapes started recording: 15 December 2000, when he met his first girlfriend at his best friends 16th birthday party. He had always had a good memory, but the thrill of young love seems to have shifted a gear in his mind: from now on, he would start recording his whole life in detail. “I could tell you everything about every day after that.”D Needless to say, people like Veiseh are of great interest to neuroscientists (神经科学专家) hoping to understand the way the brain records our lives. A couple of recent papers have finally opened a window on these peoples extraordinary minds. And such research might even suggest ways for us all to relive our past with greater clarity.E Highly superior autobiographical memory (or HSAM for short), first come to light in the early 2000s, with a young woman named Jill Price. Emailing the neuroscientist and memory researcher Jim McGaugh one day, she claimed that she could recall every day of her life since the age of 1
