Bad teeth, a heavier body? And now, weaker bones. Last week, American scientists found another bad thing about cola: It’s bad for our bones, especially women’s bones.
Well, if cola is bad for us, you may want other popular drinks , for example, energy drinks(功能饮料). Energy drinks look cool. Their makers say they give you energy and make you better at sports. So, many students drink them before exams to help them stay awake.
But wait. To keep you awake, most energy drinks have a lot of caffeine(咖啡因). They are like a strong cup of coffee or tea. If you drink a lot of them, your heart will beat faster. You will feel nervous(紧张). You could also have sleeping problems and find it hard to live without them.
Amanda Smith is a 16-year-old US junior high school student. She drinks one or more energy drinks every day. She started to do this a year ago before dance class. But now, Smith says, “I drink them whenever I feel weak or before a test. I cannot help drinking them.”
The energy you get from the drinks helps for only a short time. You may feel good for an hour or so, but then you’ll feel worse than before.

When astronauts （宇航员）are in space, they eat, sleep, wash, work and play. They do the same things as us, but they do them differently. On Earth, we put food on a plate and water in a glass. Gravity (重力) holds the food down and keeps the water in the glass. But in space, there is almost no gravity. So food can float away, and astronauts must eat and drink carefully.
Sleeping is very different in space. Some astronauts like to float in the air, but most astronauts like to be in a sleeping bag. They tie the bag to a wall so that they can’t float away.
Washing is difficult. There is no shower or bath, so astronauts must use a wet sponge（海绵）. They brush their teeth normally, but very carefully. They don’t want wet toothpaste to float around the spacecraft（太空舱）! Toilets are easy to use. A space toilet is like a vacuum (真空) cleaner with a seat.
Exercise is very important in space. On Earth, your legs carry your body, but in space, astronauts float, so they do not use their legs. This is very bad for their legs, so they must exercise for thirty minutes every day. They often use an exercise bicycle for this.
After a day’s work, astronauts relax（放松）. They listen to music, read, watch films, play games, write e-mails or talk to their friends and families by radio. Sometimes they just enjoy floating in the air. On the international Space Station, astronauts sometimes race from one end of the station to the other. The most popular pastime（娱乐） is looking out of the window, looking at space and watching the Earth.
根据上文完成以下给宇航员的建议，每空一词
1.Eat and drink carefully because food and water can __________away.
2.Tie your sleeping bag to a __________ before sleeping.
3.Wash with a __________ sponge.
4.Exercise for __________an hour every day.
5.Bring music books and videos with you so that you can __________.
