sleep a night. Others need ten hours of sleep a night. Most Americans sleep an average of seven to
eight hours a night. After age fifty, the average sleep time goes down 6.5 hours a night.
      Most people have a night when they cannot sleep. About one in three Americans has a problem with
sleep .Many of these people cannot fall asleep. The name of this problem is insomnia.

special ideas to make them sleep. Benjamin Franklin, the famous statesman and inventor, had four beds.
He moved from bed to bed to fall asleep. King Louis of France had 413 beds and hoped to fall asleep
in one of them. Mark Twain, the famous American writer ,had a different way. He lay on his side across
the end of his bed!

                                                                          Healthy eating
     What's the best thing to eat on a hot summer day? Many people would say ice cream. Yes, eating ice
 cream with some fruit on top is a great way to cool down. But think before you eat. If your body is hot
 from playing sports, it's not the best time to eat ice cream.
     When your body is hot, a lot of ice cream may give your stomach some problems, and you could get
 diarrhoea (腹泻). You can eat some ice cream after you've cooled down a bit and had some tea. Just try
  not to eat too much all at once!
     After dinner is another time people shouldn't eat or drink anything cold. Drink something hot after you
 eat, and your stomach will digest (消化) your food better. If you love fruit, summer is a great time for you.
  Go to the market and pick out the best fruit of the season. If you want to stay cool, oranges, bananas,
 pears and watermelons can help. Also, try to eat more ginger and gram. They will help you stay cool and
  healthy.
     In summer, bacteria (细菌) grow very fast and make your food go bad quickly. Try hard to keep
  yourself and your home clean in summer. Always eat clean, fresh food. When you feel like eating a cold
 dish, put vinegar in it to disinfect it. If you can't finish your food and want to eat it again next day, make
 sure you heat it enough to kill the bacteria in it. And when you put food in the fridge, make sure to keep
 the cooked food away from the uncooked food.
     Stay healthy this summer, and enjoy a nice treat now and then. What's inside your favourite snacks?

     On March 27, Saturday evening, people all over the world once again tumed  their lights off for an 
hour to help fight against global climate changes and give the world a brighter future.
      For Earth Hour 2010, many best-known buildings went dark from 8:30 to 9:30  local time, such as 
the Eiffel Tower, Big Ben, Sydney's Opera House and Beijing's  Forbidden City, etc.  Millions of businesses 
and homes around the world also tumed  off their lights.         
     Some 4 000 cities in more than 120 countries volunteered to tum off Saturday to reduce energy
consumption (能量消耗). " We have everyone from Casablanca to the camps of Namibia and Tanzania 
taking part," said Greg Boume, CEO of WWF  ( World Wildlife Fund)  in Australia, which started Earth 
Hour.          
      Earth Hour began in Sydney, Australia, in 2007.  In 2008, the event tumed into an intemational one, 
which has drawn the participation of hundreds of towns and cities worldwide. Now in its fourth year, more 
and more cities from the world took  part in Earth Hour as a show of support for action against global 
warming.        
      In a WWF survey after Earth Hour 2009, 80 million US citizens said they had  participated,  according to 
Ann.  " Earth Hour has always been an event about families and individuals as well,"  Ann said,  " and it's really 
about Americans and people all over the world standing up and saying climate change is real and we need to 
do something about it now. "        
      However, Earth Hour's energy-saving influence is limited. But WWF says that   Earth Hour's real value is 
symbolic (象征的).
