Studies have shown that a good night's rest helps us stay healthy, both mentally ( 精神上) and physically. Dr. Michael Twery, an expert（专家） on the science of sleep and sleep disorders, says,"Getting a good night's sleep is important for learning because it stores the training and learning exercises into our long-term memory while we're sleeping 7 to 8 hours. And then the next morning, our mind is better prepared to perform. "
But what about getting some rest during the middle of the day? Does napping (sleeping for a short time) also help our brain work better? If it is really helpful, then how long can a proper nap last?
Napping can help babies and young children learn better. Also, it can stop older people suffering (遭受) from memory loss. Some people have sleep problems at night, so they nap during the day as a way of paying off a sleep debt. They hope napping may make them feel less tired and sleepy during the day.
In America, it is a shame for people to admit (承认) that they do take a nap. They suppose napping shows they are weak or short of energy. That only children, the very old, sick or lazy people nap is a widely-accepted opinion. However, that may be changing. Many offices now offer napping rooms, and napping cafes are appearing in many U. S. cities.
Unlike America, napping is part of a normal, everyday life in other parts of the world. For example, China is generally considered as a land of nappers. Researchers found nearly 60 percent of old Chinese people took a nap after lunch and most of them napped for about an hour. The study found that people who took an hour-long nap did much better on mental tests than those who did not nap or who napped for longer periods. It seems that the most helpful nap lasted for about an hour.
But Dr. Michael Twery mentions that an hour-long nap may be too long for young, healthy adults. "We're suggesting that we try to nap for about 30 minutes or less. And 30 minutes is enough to help us feel more awake. " He also found that someone who naps because of bad sleep at previous night may not experience the same improvements from napping as a healthy, well-rested person would. So, the right thing to do is to get enough sleep at night and take a proper nap for about 30 minutes. But remember not to take a nap later than 3:00 in the afternoon, which may cause a sleep problem.
1.According to the passage, Dr. Michael Twery probably agrees that
A. napping only helps the healthy, well-rested people improve their brain performance
B. napping shows people are very sick and lazy in some countries
C. people had better take a nap before 3:00 in the afternoon
D. young, healthy adults should nap longer than older people
2.The words "paying off a sleep debt" probably mean
A. having some sleep during the work
B. making up for shortness of sleep

D. improving the sleep quality
3.What can we know from the passage?
A. Only the one-hour napper group finished their mental test.
B. China has the most young nappers in the whole world.
C. People should be better prepared to get a good nap.
D. More and more Americans are accepting napping.

九年级英语单词拼写困难题查看答案及解析
Studies have shown that when students join in team sports, their overall educational experience is greatly improved. In fact, no matter they are good at sports or not, there are still benefits to be got from playing team sports! Here are four lessons team sports can teach students.
Have a Bigger Picture
At some point in life, everyone goes through challenges. People may think that the choices they make only affect themselves, but as it turns out, that simply isn't true! Team sports teach students about friendship and a sense of belonging to something bigger than themselves. When they play sports on a team, they quickly learn that every choice they make has an influence on their teammates and their opponents(对手)!
Be Decisive
Making choices can often be difficult for many people since they often over-complicate(过度复杂化)very simple decisions. Playing team sports gets students to reason and come to a decision faster than they might in their day-to-day life. And then, making quick decisions can help students develop a sense of self-confidence.
Never Give Up
It's always exciting to win in life, but sometimes the greater lessons come from losses in team sports games. To deal with those losses, students should accept them peacefully, move on and try again! Team sports teach students that great comebacks do happen and a loss is never final if they refuse to give up!
Put Others First
Perhaps the most important lesson that team sports can teach students is how to put others first in difficult situations. Sometimes, they may have to be ready for being second-best for the greater good, because there is often more at play than they can see at first. Sometimes the most pleasing choice students can make is the one to help others even when it is inconvenient. Learning self-sacrifice(自我奉献）is a lesson that students will certainly carry throughout the course of their life!
Students don't have to be athletic to succeed at sports, and there are countless benefits of team sports for them.
1.Do students need to be good at sports in order to benefit from team sports?
2.Why do many people find it difficult to make choices?
3.How should students deal with losses in team sports games?
4.What is probably the most important lesson students can learn from team sports?
5.What's the main idea of this passage?
