生活越过越好，人却越来越累。虽然不愁吃不愁穿，可是每天总有那么多烦恼。我们总是把自己搞得很累，顾虑这个，抱怨那个，人活一世，说长不长，说短不短，忧虑也是过一天，开心也是过一天。人还是活得洒脱点好！今朝有酒今朝醉，事情来了就解决，别总是放在心里累坏自己。昨天再好，也回不去；明天再难，也要抬脚继续。日子，过得是心情。压力大的时候，就出去走走，听听歌，看看窗外抒解下心情。看开一点，放轻松一点，带着好心情，过好每一天！

Life is getting better and better, but people are getting tired. Although I don't worry about food and clothing, I always have so many troubles every day. We always make ourselves very tired. We worry about this and complain about that. People live a lifetime, saying whether it is long or short. Worry is also a day, and happiness is also a day. People still live free and easy! If you are drunk today, you can solve the problem when it comes. Don't always put it in your heart and spoil yourself. No matter how good yesterday was, I couldn't go back; No matter how difficult it is tomorrow, we must raise our feet and continue. Life is a mood. When the pressure is high, go out for a walk, listen to songs, look out the window and express your feelings. Look open, relax, live every day with a good mood!

As space science develops,man has learned more and more about space.Space is not only amazing but also dangerous.While working in space,spacemen are facing danger.

Scientists have found out that radiation is the greatest danger to spacemen in space.When spacemen are working in space,they are in danger of radiation from the sun and other stars,which is bad for their health.The damage done by radiation won’t be discovered until their children or even grandchildren are born.Some special medicine may work a little,but no really helpful medicine has been.

Space junk is also thought a great danger to spacemen.It’s reported that there are 9,000 man-made things flying in space.About 30% of these are man-made satellites,10% are spaceships,and the rest are space junk.An explosion in 1996 made a cloud of 300,000 fragments,each at least 4 mm in size,and even a small piece of these knocked against a spaceship window and did some damage.Scientists are watching and reporting any possible danger all the time.They are working on helpful ways to do with space junk.

Although space is really dangerous,it interests everyone on the earth.In the near future,it may become usual for people to spend a few days in a space hotel.We may even choose to leave the earth and live in space for a few years.So we should care for space and do something to help improve the space environment.

随着空间科学的发展，人类对空间的了解越来越多。 太空不仅令人惊奇，而且很危险。 在太空工作时，宇航员面临着危险。  

科学家已经发现辐射对太空中的宇航员是最大的危险。 当宇航员在太空工作时，他们面临着来自太阳和其他恒星的辐射的危险，这对他们的健康有害。 辐射造成的损害直到他们的孩子甚至孙辈出生后才会被发现。 一些特殊的药物可能起一点作用，但没有真正有用的药物。  

太空垃圾也被认为对宇航员有很大的危险。 据报道，有9000个人造物体在太空中飞行。 其中大约30%是人造卫星，10%是宇宙飞船，剩下的是太空垃圾。 1996年的一次爆炸产生了30万个碎片，每个碎片至少4毫米大小，甚至其中的一小块碎片撞到了飞船的窗户上，造成了一些破坏。 科学家们一直在观察和报告任何可能的危险。 他们正在研究处理太空垃圾的有效方法。  

虽然太空真的很危险，但它引起了地球上每个人的兴趣。 在不久的将来，人们在太空旅馆住上几天可能会变得很平常。 我们甚至可能选择离开地球，在太空生活几年。 所以我们应该关心太空，做一些事情来帮助改善太空环境。
