已water为话题的作文 提示词：precious,liquid gold,important,we need water for.,without water

答案

Water is the common name applied to the liquid form (state) of the hydrogen and oxygen compound H2O.Pure water is an odorless,tasteless,clear liquid.Water is one of nature's most important gifts and kind of liquid gold to mankind.Essential to life,a person's survival depends on drinking water.We can't live without water.Water is one of the most essential elements to good health -- it is necessary for the digestion and absorbtion of food; helps maintain proper muscle tone; supplies oxygen and nutrients to the cells; rids the body of wastes; and serves as a natural air conditioning system.Health officials emphasize the importance of drinking at least eight glasses of clean water each and every day to maintain good health.
Water is a key component in determining the quality of our lives.Today,people are concerned about the quality of the water they drink.Although water covers more than 70% of the Earth,only 1% of the Earth's water is available as a source of drinking.Yet,our society continues to contaminate this precious resource.Water is known as a natural solvent.Before it reaches the consumer's tap,it comes into contact with many different substances,including organic and inorganic matter,chemicals,and o ther contaminants.Many public water systems treat water with chlorine to destroy disease-producing contaminants that may be present in the water.Although disinfection is an important step in the treatment of potable water,the taste and odor of chlorine is objectionable.And,the disinfectants that are used to prevent disease,can create byproducts which may pose significant health risks.Today,drinking water treatment at the point-of-use is no longer a luxury,it is a necessity!Consumers are taking matters into their own hands and are now determining the quality of the water they and their families will drink by installing a drinking water system that will give them clean,refreshing,and healthier water.

Here are some interesting facts about Why Water is Important.
Water is necessary to all living things.
Water is all around us,in the air and in the ground.It is in milk,vegetables,fruit,meat,leaves,trunks,roots,and branches of a tree; it is even in stones.
Water is used for many things:
To drink:people should drink 8 glasses of water each day to stay healthy.
To wash things:dishes,cars,clothes,ourselves as needed.
To cook things in (eggs,vegetables); to use in things we cook (cakes,soup).
To put out fires.
To play in:pools,ponds,lakes,oceans; or to play with when using hoses,sprayers,or sprinklers.
To water plants,lawns,trees,bushes.
To transport cargo and people on ships or boats.
More plants and animals live in water (saltwater or in fresh water) than on land.
Seventy percent of the earth is made up of water.Huge bodies of water can absorb and store large amounts of heat coming from the sun especially during daytime and the summer season.During the winter and the nighttime,the gradual cooling of water can warm up the air.This property of water helps stabilize the temperature of the oceans thus creating a favorable habitat for marine life.
Because of water鈥檚 high specific heat,it can keep the earth鈥檚 fluctuations in temperature on land or at sea within limits that is favorable for life.Since organisms (animals,floral and fauna) are made up of water as well,they are more capable of resisting changes in temperature.Ninety-seven percent of the earth鈥檚 water is in oceans and seas while two percent is found on the icecaps.
Water needs to be considered an essential nutrient.Because of easy access we take water for granted and do not realize the importance of proper hydration.According to experts,water is ranked second only to oxygen as essential for life.Your overall body weight is 2/3 water.A person can survive about two months without food,but only a few days without water.
Water is the most abundant ingredient in the human body through all phases of growth and development.Every system in your body depends on water to function.
Water is essential to your body's temperature regulation,keeping it cool through perspiration.
Water flushes out toxins and wastes.
Water is a major component of blood which carries nutrients and oxygen to and from all cells.
Water provides a moist environment for all body tissues.It is the major component of saliva and mucous which lubricates the membranes that line our digestive system beginning with the mouth.Mucous membranes in the nose and eyes function better when well hydrated.
Water cushions joints and protects tissues and organs like the brain from shock and damage.
Water helps maintain a healthy weight.It is hard to distinguish between hunger and thirst.If you feel hungry,drink some water first and then reassess your hunger status.
Water is an important part of your daily bodily functions,so it is important to continually replenish it.Each day,your body loses 2-3 quarts of water through sweat,urination,excretion and breathing.The body loses even more water if you exercise,live in hot or dry climates,consume high fiber diets,and consume caffeine or alcohol.It is recommended to drink 8-10 cups of fluid a day,adding more water if any of the previously stated situations apply.
Signs of illnesses,such as fever,vomiting or diarrhea,cause your body to lose additional fluids.In these cases,you should drink more fluids and may even need oral rehydration solutions like Gatorade or Powerade.Bladder infections and urinary tract stones also require increased water intake.On the other hand,conditions such as heart failure and certain conditions relating to the kidney,liver or adrenal glands may impair excretion of water and may require a limited fluid intake.
Consuming caffeinated beverages may be a concern because caffeine acts as a diuretic and can cause increased urination.Caffeine is found in coffee,teas,and many soft drinks.Try to drink caffeinated beverages in moderation and focus on consuming more water.
To help increase your water consumption,try:
Adding lemon or lime to water.Drink no-calorie flavored water.
Eat foods that have higher water content like:cucumber,watermelon,lettuce,celery,grapes,oranges,tomatoes.
Drink non-fat milk.
Keep a water bottle handy.
Mix ice and fruit in a blender to create a smoothie.
Try decaffeinated tea or coffee.
Soda and juice are okay once in awhile,but it is preferable to drink other liquids because soda and juice have more calories and sugar than water.Soda has caffeine while water and juice do not.
