同學们一定对宇航员在太空的饮食起居感兴趣吧？本文从洗漱、三餐、娱乐、睡眠等方面来展现宇航员在太空的日常生活。

Many people may wonder what the astronauts life was like when working in space. In fact， they did many of the things as we do on Earth.

They brush their teeth， wash their hair and go to the bathroom. However， because of the microgravity（失重）environment，they take care of themselves in different ways. They wash their hair by using the no?rinse shampoo to get it clean because there are no real showers in the spaceship.

Astronauts eat three meals a day： breakfast， lunch and dinner. But how much they eat depends on the astronauts. A small woman astronaut often needs only about 1，900 calories （卡路里） a day， while a large man requires about 3，200 calories. So there are many kinds of foods ready， such as fruits， nuts， chicken， beef and seafood. They can also drink coffee， tea and orange juice.

Astronauts can have much fun， too. They look out of the window， enjoying the wonderful sunsets and sunrises which happen every 45 minutes. Very often， they play with their food or even jokes on their workmates. Believe it or not， astronauts can even spend weekends， when they can watch movies， play music， read books and talk to their families.

After a long day at work， ▲ .Just like on Earth， an astronaut goes to bed at a certain time， then wakes up and prepares for work again. But there are a few differences. Astronauts have to sleep in sleeping bags in special cabins （柜子）. Generally，astronauts are planned to have eight hours of sleep. Like on Earth， they may wake up in the middle of their sleep to use the toilet. And astronauts also have dreams.
