Every morning you get up, wash your face, brush your teeth, eat breakfast and get ready for your day. These daily actions are so common that you don't think about them much. But what if you were in space? There is no gravity there, so weights are not as heavy as they are on Earth. When you drop something, it doesn't fall to the floor. It floats slowly away in the air. This means that astronauts can't just put down a tool. They need to tie it down. And how do astronauts drink? In space, water just breaks into small drops and hangs in the air.

每天早上你起床、洗臉、刷牙、吃早飯然后開(kāi)始一天的生活。這些日常行為很常見(jiàn)你不會(huì)考慮太多。但是如果你在太空中呢？那里沒(méi)有重力，重量不像在地球上那樣重。當(dāng)你扔?xùn)|西的時(shí)候，它不會(huì)掉到地上，會(huì)在空中慢慢飄走。這也就意味著宇航員們不能把工具放下。他們需要把它系起來(lái)。那么宇航員們?nèi)绾魏人?？在太空中水?huì)分解成小水滴懸浮在空中。

Well, astronauts eat and drink differently in space. They have special plates so that their food doesn't float away. They use special bags for drinks so that the drink stays inside.

宇航員在太空中吃飯喝水是不一樣的。他們用特殊的盤(pán)子所以食物不會(huì)飄走。他們用特殊的包來(lái)裝飲品，因此飲品才不會(huì)流出來(lái)。

Sleep is also different in space. Astronauts tie themselves to the wall so that they don't float around when they are sleeping. Since they have to work hard, they need to get plenty of rest. The sun rises and sets so often that it can be confusing. The astronauts have alarms and sometimes music to wake them up.

在太空中睡覺(jué)也是不一樣的。宇航員們把自己系到墻上面因此他們?cè)谒X(jué)的時(shí)候才不會(huì)飄浮不定。因?yàn)樗麄冃枰ぷ?，所以他們需要充足的睡眠。頻繁的日出日落會(huì)讓人感覺(jué)時(shí)間錯(cuò)亂，宇航員們有鬧鐘有時(shí)候音樂(lè)會(huì)把他們叫醒。

Exercise is important for astronauts as well. Since there is no gravity and astronauts float instead of walking or running, their muscles become weak very quickly. They have to exercise on special machines every day so that this doesn't happen. No one wants to become ill in space and exercise helps them stay healthy.

鍛煉身體對(duì)宇航員們來(lái)說(shuō)也很重要。因?yàn)闆](méi)有重力，宇航員是飄著的不能走路或者奔跑，他們肌肉很快就會(huì)變得無(wú)力，他們必須每天鍛煉防止這種情況發(fā)生。沒(méi)有人想在太空中生病，鍛煉能讓他們保持健康。

However, it is not all hard work in space. When they are not doing science experiments, writing reports or exercising, there is a little time for fun. They watch movies, read the news and call family members and friends. The astronauts on the International Space Station can even connect to the Internet.

然而在太空中也不全是辛苦的工作。當(dāng)他們不做科學(xué)實(shí)驗(yàn)、寫(xiě)報(bào)告或鍛煉的時(shí)候，也會(huì)有一些娛樂(lè)時(shí)間。他們看電影、看新聞或者給家人朋友打電話，在國(guó)際太空站的宇航員甚至可以連接網(wǎng)絡(luò)。
