题目内容
4.What do you,the trees,and a bird have in common?(71)B All living things must have water to survive,whether they get it from a water fountain,a rain cloud,or a little bottle attached to the side of a bird cage.(72)C Water makes up more than half of your body weight and a person can't survive for more than a few days without it.Why?Your body has lots of important jobs and it needs water to do many of them.For instance,your blood,which contains a lot of water,carries oxygen to all the cells of your body.Without oxygen,those tiny cells would die and your body would stop working.
Water is also in lymph,a fluid(流体) that is part of your immune syst(免疫系统),which helps you fight off illness.(73)A Water is needed for digestive juices,urine,and poop.And you can bet that water makes up most of sweat.
In addition to being an important part of the fluids in your body,each cell depends on water to function normally.
(74)E Any fluid you drink will contain water,but water and milk are the best choices.Lots of foods contain water,too.(75)G You could probably tell that if you've ever bitten into a peach or pear and felt the juices dripping down your chin!Vegetables,too,contain a lot of water-think of biting into a fat tomato from the garden.
A.You need water to digest your food and get rid of waste,too.
B.You all need water.
C.Without water,your body would stop working properly.
D.How much is enough?
E.Your body doesn't get water only from drinking water.
F.When you drink is also important.
G.Fruit contains quite a bit of water.
