The Drink Your Body Needs MostI Our bodies are estimated to be about 60% to 70% water. Blood is mostly water,andour muscles,lungs,and brain all contain a lot of water. Water is needed to regulate bodytemperature and to provide the means for nutrients（滋养物）to travel to all our organs. Water also transports oxygen to our cells,removes waste,and protects our joints andorgans.2 We lose water through urination（排尿）,respiration（呼吸）,and by sweating. If youare very active,you lose more water than if you do not take much exercise.Symptoms ofmild dehydration（脱水）include chronic pains in joints and muscles, lower back pain, headaches, and constipation（便秘）.A strong smell to your urine, along with a yellowcolor indicates that you are not getting enough water. Thirst is an obvious sign ofdehydration and in fact,you need water long before you feel thirsty.3 A good rule of thumb（好的做法）is to take your bod犷weight in pounds and divide thatnumber in half. That gives you the number of ounces（盎司）of water per day that youneed.For example,if you weigh 160 pounds,you should drink at least 80 ounces of waterper day.If you exercise you should drink another 8-ounce glass of water for every 20minutes you are active.If you drink coffee or alcohol,you should add at least an equalamount of water. When you are traveling on an airplane,it is good to have 8 ounces ofwater for every hour you are on board the plane.4 It may be difficult to drink enough water on a busy day.Be sure you have water handy atall times by keeping a bottle for water with you when you are working,traveling,orexercising.If you get bored with plain water,add a bit of lemon for a touch of flavor.Thereare some brands of flavored water available,but some of them have sugar or artificial sweeteners that you don't need. The amount of water your body needs per day is closely related________.A:in your bodyB:without waterC:before longD:for a changeE:on a busy dayF:to your weight

Water is needed to regulate body temperature and to provide the means for nutrients（滋养物）to travel to all our organs. Water also transports oxy-gen to our cells,removes waste,and protects our joints and organs.2. We lose water through urination（排尿）, respiration（呼吸）, and by sweating. If you are very active,you lose more water than if you do not take much exercise.Symptoms of mild dehydration （脱水）include chronic pains in joints and muscles,lower back pain,headaches,and constipation（便秘）.A strong smell to your urine,along with a yellow color indicates that you are not getting enough water. Thirst is an obvious sign of dehydration and in fact,you need water long before you feel thirsty.3 .A good rule of thumb（好的做法）is to take your body weight in pounds and divide that num- her in half. That gives you the number of ounces（盎司）of water per day that you need.For ex-ample,if you weigh 160 pounds,you should drink at least 80 ounces of water per day.If you ex- ercise you should drink another 8-ounce glass of water for every 20 minutes you are active.If you drink coffee or alcohol,you should add at least an equal amount of water. When you are traveling on an airplane,it is good to have 8 ounces of water for every hour you are on board the plane.4 .It may be difficult to drink enough water on a busy day.Be sure you have water handy at all times by keeping a bottle for water with you when you are working,traveling,or exercising. If you get bored with plain water,add a bit of lemon for a touch of flavor. There are some brands of fla-vored water available,but some of them have sugar or artificial sweeteners that you don't need. Paragraph 3________A: Ounces of water needed per dayB:.Importance of waterC: Composition of waterD: Signs of dehydrationE: Supply of waterF: Necessity for bringing a bottle for water

Lisa was running late.Lisa,25,had a lot to do at work,plus visitors on the way:her parents were coming in for Thanksgiving from her hometown.But as she hurried down the subway stairs,she started to feel uncomfortably warm.By the time she got to the platform,Lisa felt weak and tired—maybe it hadn′t been a good idea to give blood the night before,she thought.She rested herself against a post close to the tracks.
Several yards away,Frank,43,and his girlfriend,Jennifer,found a spot close to where the front of the.train would stop.They were deep in discussion about a house they were thinking of buying.
But when he heard the scream,followed by someone yelling,"Oh,my God,she fell in!"Frank didn′t hesitate.He jumped down to the tracks and ran some 40 feet toward the body lying on the rails."No!Not you!"his girlfriend screamed after him.
She was right to be alarmed.By the time Frank reached Lisa,he could feel the tracks shaking and see the light coming.The train was about 20 seconds from the station.
It was hard to lift her.She was just out.But he managed to raise her the four feet to the platform so that bystanders could hold her by the arms and drag her away from the edge.That was where Lisa briefly regained consciousness,felt herself being pulled along the ground,and saw someone else holding her purse.
Lisa thought she′d been robbed.A woman held her hand and a man gave his shirt to help stop the blood pouring from her head.And she tried to talk but she couldn′t,and that was when she realized how much pain she was in.
Police and fire officials soon arrived,and Frank told the story to an officer.Jennifer said her boyfriend was calm on their 40-minute train ride downtown—just as he had been seconds after the rescue,which made her think about her reaction at the time."I saw the train coming and I was thinking he was going to die,"she explained.
How did Frank save Lisa?A.By lifting her to the platform.
B.By helping her rise to her feet.
C.By pulling her along the ground.
D.By dragging her away from the edge.
