Ⅵ.閱讀理解

• 31．How do you remember the way to your house？Where do dreams come from？It is your brain that does these things．A British scientist showed that"sleep can improve one's memory．"It's not a dream for students to study when they sleep．In fact，your brains is working day and night．If you learn words before bed，a certain part of the brain may help you to remember the words while you sleep．What's more，another scientist in the USA found that there was a"talent button（天才按鈕）"in the human brain．It might make a person more talented．
  There are more interesting things about the brain．Your brain uses less energy than a fridge light．Just two bananas can give the brain enough energy to work for a whole day．According to some scientists，yawning（打哈欠） keeps our brains"cool"，which makes us think quicker．
  Here are some pieces of advice to keep a good brain：
  ?Eat healthy food．
  ?Get a lot of playtime or exercise．
  ?Don't drink or smoke．
  ?Use your brain a lot．

Ⅶ.閱讀短文，根據(jù)短文內(nèi)容回答問題

• 32．Sleep is very important. A person who does not sleep dies faster than a person who does not eat. We spend about one third of our lives in sleeping. That's about 121 days a year!
      How much sleep do we need？ We are all different. A baby needs 16 hours of sleep every day. Children 6 to 12 years old need an average（平均） of 10 to 12 hours of sleep. Teenagers need 9 to 10 hours of sleep. An adult needs an average of 7 to 8 hours a night. There are some people who need only 3 hours of sleep. Others need 10 hours of sleep. After the age of 50， the average sleep time goes down to 6.5 hours a night. We need less sleep as we get older.
      About one in three Americans has a problem with sleep. Many of these people cannot fall asleep. The name of this problem is insomnia（失眠）. Some people say， "I didn't sleep all night." But that's not really true. They may sleep lightly and wake up several times. In the morning， they only remember the times they were awake， so they think they were awake all night.
      This is not a new problem. Many famous people in history had insomnia. Some of these people had special ideas to make them sleep. Benjamin Franklin had four beds. He moved from one to the other to fall asleep. Mark Twain had a different way. He lay on his side across the end of the bed!
  （1）Do you spend one third of your lives in sleeping？

  
  （2）If you are 13 years old， how many hours of sleep do you need every day？

  
  （3）Do we need less or more sleep as we get older？

  
  （4）Did many famous people in history have insomnia according to the passage？

  
  （5）What is the purpose of the passage？
