[对应知能达标训练P21] Ⅰ.阅读理解 Proper diet and regular exercise seem to be the only method for losing weight.However，the importance of water should be added in the process.While medical science has proven the positive effects of water，most people still do not drink enough each day. The reason why water is so important for weight loss has something to do with metabolism (新陈代谢) of fat.The liver (肝脏) is in charge of this process when it comes to turning stored fat into energy.However，the liver is also responsible for helping the kidneys (肾脏) that need enough water in order to function properly.The liver has to perform all the functions of the kidneys on its own when they are short of water.This means the liver doesn't have enough energy to metabolize fat.So，drinking water allows the kidneys to focus on their job and the liver to focus on its job. Also，studies have shown that water can make us feel full when drunk before meals.Without even making an effort，most people who drink a glass of water before a meal will eat 33% less.This is due in part to the fact that they simply get fuller quicker because the water is taking up space.The other reason is that the food will expand as soon as it hits the water-filled stomach. Water is important for every aspect of the health of the human body.By drinking more water and improving the health of the body，weight loss goals can be achieved with greater ease.
