Question

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 2?liter soda bottle.You probably guess that water is lost when you sweat—especially?? on a hot day.

But your body also loses water in an almost invisible way—evaporation (蒸發(fā))．Water escapes from your body through your skin and in your breath.How？Your breath contains droplets (小滴) of water that are usually too tiny to see.They become visible for a quick second in the cold when you can “see your breath”．But water evaporates this way all year round.Your skin also contains water，which escapes in tiny droplets that go into? the air.The water in your skin evaporates into the air，but fortunately，your body can replace the water it loses so your skin doesn’t dry out.

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 rely_on 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.

Answer 1

【答案】

1.C

2.D

3.B

4.C

【解析】

1.

解析　細(xì)節(jié)理解題。根據(jù)第一段可知，人喝水的主要原因是人體每天都通過各種途徑失去很多水，為了保持人體的水平衡，人們才需要不斷地喝水。

2.2】　D

解析　細(xì)節(jié)理解題。根據(jù)第一段最后一句和第二段前兩句可知，出汗、蒸發(fā)及呼吸是人體消耗水分的途徑，而吃飯是獲得水分的有效途徑，所以D項符合題意。

3.3】　B

解析　細(xì)節(jié)理解題。根據(jù)第二段最后一句中“...but fortunately，your body can replace the water it loses so your skin doesn’t dry out.”可知，人體為皮膚提供水分是為了使皮膚不干燥。

4.4】C

解析　詞義猜測題。根據(jù)上文并聯(lián)系下文的“...and that’s why it’s also a good idea to drink water every day.”可判斷，該詞組的意思是“依靠”，只靠吃水果、蔬菜來補(bǔ)充水分是不夠的。
