　　Drinking water is good for your health．There are some scientific ways of drinking water．

　　1．It is the best medicine to drink two glasses of water in the morning．

　　2．Drink clean water．

　　3．Drink the water that has not been boiled．

　　Many people think boiled water is safe and good to people's health．In fact, it is not true．The boiling point of water is 100℃．By boiling it, most bacteria(细菌)in water can be killed．In the past, the water was less polluted．So boiling was a good way to make clean water．But heavy metals and other dangerous things in today's water are much more terrible than bacteria．Boiling doesn't fix that problem．And boiling water may give us more of the dangerous things in our glass．

　　4．Never use soft drinks to take the place of water．

　　5．Water is also needed in winter．

　　6．Drink water at the right time．

　　1)After getting up in the morning, you have less water in your body, because you weren't drinking for the whole night．So you should drink some water to keep your health after getting up in the morning．That can prevent high blood pressure, cerebral hemorrhages(脑溢血)and so on．

　　2)Drinking water at about 10 am helps your body keep enough water．

　　3)Drinking water at about 3 pm can clean out the wastes in your body．

　　4)About eight o'clock in the evening is the best time to drink water．Your blood gets thicker when you sleep．Water will make your blood less thick．

　　Besides, we should drink 2L of water every day．Water is so important for our life．We should drink water often．

　　A group of swans flew down to a beach where a crow(乌鸦)was jumping around．The crow watched them with disdain(鄙视)．

　　“You have no flying skills at all!” he said to the swans．“All you can do is to move your wings．Can you turn over in the air? No, that's beyond you．Let's have a flying competition．I'll show you what real flying is!”

　　One of the swans, a strong young male, took up the challenge．The crow flew up and began to show his skills．He flew in circles, performed other flying tricks, and then came down and looked proudly at the swan．

　　Now it was the swan's turn．He flew up, and began flying over the sea．The crow flew after him, making all kinds of comments(评价)about his flying．They flew on and on till they couldn't see the land and there was nothing but water on all sides．The crow was making fewer and fewer comments．He was now so exhausted that he found it hard to stay in the air, and had to struggle to keep himself from falling into the water．

　　The swan pretended(假装)not to notice, and said, “Why do you keep touching the water, brother? Is that another trick?”

　　“No,” said the crow．He knew he had lost the competition．“I'm in trouble because of my pride! If you don't help me, I'll lose my life…”

　　The swan took pity on him, and took him on his shoulders and flew back to the beach．
