     An apple a day keeps the  doctor away. Well, milk may work in the same way！

     Milk is the natural food for mammalian (哺乳动物) babies. It helps them grow strong because it is rich

  in protein (蛋白质),calcium (钙) and witamins. Milk can also help you sleep better because it calms you

  down. But remmber to drink milk with care. Find out how old the milk is. Make sure it is fresh and hasn't

  gone bad. Don't drink milk when yoour stomach is empty. Eat some bread or corn at  the same tome.

 That'll help you take in more protein and vitamins. Doctors say teens need at least 500ml of milk a day.

 That's  two to three  cups.

     Milk-drinking started ling ago, as early as 6000~8000BC. At that time pepole started to keep cows,

 sheep and goats to get their milk.

     Of course what you drink today isn't that fresh from the cow. People cool the fresh milk down to 4 ℃

 to stop the bacteria growing. In factories, milkis pasteurized (灭菌) to stop it going bad. After

 disinfection (消毒) and packaging , it goes to the supermarkets.

     Yogurt (酸奶) also comes from milk. People make some special bacteria to change the  taste of milk

 and make the nutrients (营养) in it easier for people to take in . Maybe that's why it's  getting more

  popular with pepole!
