Barley was an unexpected find: The crop was domesticated in western Eurasia and didn’t become a _____(33)food in central China until about 2000 years ago, according to the researchers. Based on that timing, they suggest barley may have _____(34)in the region not as food, but as_____(35)material for beer brewing beer.
part 2原文
Beer recipes change over time. Hops, for example—which give many a modern brewski its bitter, citrusy flavor—are a relatively recent addition to the beverage, first mentioned in reference to brewing in the ninth century. Now, researchers have found a surprising ingredient in residue from 5000-year-old beer brewing equipment. While excavating two pits at a site in the central plains of China, scientists discovered pottery fragments from pots, funnels, amphorae, and stoves (stove fragment pictured). The different shapes of the containers suggest they were used to brew, filter, and store beer—they may be ancient “beer-making toolkits,” and the earliest direct evidence of beer brewing in China, the researchers report online today in the Proceedings of the National Academy of Sciences. To test that hypothesis, the team examined the yellowish, dried dregs inside the vessels. about a third of the starch grains they found were pitted, swollen, folded, or distorted—types of mangling that can occur during the malting and mashing needed to make beer. The majority of the grains—about 80%—were from cereal crops like millet and barley, and about 10% were bits of tubers, including yam and lily, which would have sweetened the brew, the scientists say. Barley was an unexpected find: The crop was domesticated in western Eurasia and didn’t become a staple food in central China until about 2000 years ago, according to the researchers. based on that timing, they suggest barley may have arrived in the region not as food, but as fodder for brewing beer.
part 3As 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 perk them right up again. During vigorous exercise, our muscles tire as they run out of fuel and build up waste products. Muscle performance can also be affected by a phenomenon called “central fatigue,” in which an imbalance in the body’s chemical messengers prevents the central nervous system from directing muscle movements effectively. It was not known, however, whether central fatigue might also affect motor systems not directly involved in the exercise itself—such as those that move the eyes. To find out, researchers gave 11 volunteers a carbohydrate solution either with a moderate dose of caffeine—which is known to stimulate the central nervous system—or as a placebo without, during 3 hours of cycling. After exercising, the scientists tested the cyclists with eye-tracking cameras to see how well their brains could still control their visual system. The team found that exercise reduced the speed of rapid eye movements by about 8%, preventing their ability to capture new visual information. The caffeine—the equivalent of two strong cups of coffee—was sufficient to counteract this effect, with some cyclists even displaying increased 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.
