Researchers say sleep is probably the best tool we have for memory and learning. Getting a good night39。s sleep is important for the learning and memory process. It39。s important because it stores （儲(chǔ)存） the training and learning exercises into our memory forever while we39。re sleeping 78 hours in bed. And then the next morning when we wake up, our mind is better prepared to act on that information, Twery, an expert on the science of sleep said. But what about getting rest during the middle of the day? Past studies have shown that napping can help babies and young children learn better. In fact, napping can help older adults with their brain performance and may also help this group of people fight off agerelated （年齡相關(guān)） memory loss. The researchers studied 3, 000 people and found that those who took an hourlong nap did much better on mental （智力的） tests. The hourlong nappers also did better on the tests than those who napped for shorter and longer periods. But researchers note that these findings are for those over 65, and for young, healthy adults, an hourlong nap may be too long. At present, we39。re suggesting that we try to nap for about 30 minutes or less. Thirty minutes is enough to remove （消除） the pressure and will help us feel more awake. If we nap longer, we will get trapped into （陷入） the deep sleep, which can be hard to get out of, Twery said. This feeling is called sleep inertia （遲鈍）—the period when you awake from a very deep sleep. For a time, you are unable to think clearly.（1）From Paragraph 1, a good night39。s sleep ________.
