Water is the most important in our lives. Not Many people understand this but it’s quite true. The human body can go without food for a long time. We’ve got many examples for this. Yet two or three dayswithout water can usually make people die. Man can’t live without water.
Many people don’t understand how much water the human body needs to work well, and many people, especially young people, do not drink enough water, even in very hot weather. About two thirds of our body is water. When we do sports, some of the water will get away from our body. If we don’t drink some water, our body won’t have enough water. And if we don’t have enough water, we’ll feel tired and many of us will get ill. So you know how important water is to us.
But at present we face water crisis(危机). Water is becoming less and less. So， we should protect water resources(资源) and try our best to save water in our daily life. Here are some tips for saving water:
1. Turn off the tap(水龙头) in lime.
2. Take shorter showers.
3. Don’t let water run while washing your face and reuse the water after we finish washing.
4. Encourage your friends and neighbors to join in the action of saving water.
【小题1】 Nobody can live without water.
【小题2】 About one third of our body is water
【小题3】 If one doesn't have enough water, he’ll feel tired and may get ill.

If you have a bottle of water recycled(再利用) from urine(尿), would you drink it? Astronauts at the ISS may soon do so.
NASA(美国航空航天局) said it would use a high-tech machine to recycle wastewater at the ISS. The machine will recycle water for washing hands, shower water, water for brushing teeth and even urine to make drinking water. It will save millions of dollars each year.
At present, each ISS astronaut uses about 4.4 liters(升) of water every day. It costs about 24 million dollars a year to send water up to the ISS. A liter of water costs about $ 11,000.
The machine will be sent to the ISS later. NASA hopes it will recycle about 93% of all the water used on the station.
Will the water be clean? Different chemicals will be put in the wastewater. The water will be heated to 130℃ to kill bacteria(细菌). Scientists say that the recycled water is thousands of times better than the water from a city tap.

Summer is coming soon. When is the best time for swimming in the day in summer?

If you would like to swim indoors, a good time in the day is the early hours-the body has the most energy to use because the body has woken up and will be ready for all kinds of different activities of the day. The body is going to work with enough energy and therefore a person will feel more comfortable if he swims during the early hours of the day.

Swimming early in the day can also be good for anyone who plans to swim outdoors. The conditions outside will be excellent: the water will not be too cold or too hot, and the air will be just clean and fine. Everything is suitable.

Usually, it is not a good idea to swim later in the day because one’s body is tired after work for a whole day and also the weather conditions can be the worst in the later parts of the day.

However, there are still some exceptions. Different people feel different and one’s body acts differently at different time of the day. When a person is feeling active and is not tired at all after work, it may be a better time to swim for him than for others. If he is alert(警觉的) that time, he is safe in the water.

In a word, the best time can change for every person. The person’s body condition decides when the best time for swimming is.
