As you can see,water works hard in your body every day.That's why it's important  to give your body the water it needs to carry out all its different jobs.On a regular day,your body loses 2 to 3 quarts of water--enough to fill a 2liter soda bottle.You probably guess that water is lost when you sweat--especially   on a hot day.

Eating and drinking is one way to replace the water your body loses.Most foods have a lot of water in them,especially fruits and vegetables.Grapes,watermelons,oranges,and cantaloupes are delicious and full of water. But you can't _ food alone to get that water back,and that's why it's also a good idea to drink water  every day.You might have heard someone say that people need to drink 6 to 8 cups (1.4 to 1.9 liters) of water each day.Depending on how much  water you're getting from foods and other liquids,6 to 8 cups might not be necessary.If you eat a lot of fruits and vegetables,or you like to eat soup every day,you'll get some of the water your body needs. Your body has to give enough water to your skin in order to  _  .
