Life in space is much different from life on earth. How do astronauts live in space?

　 Eating In the past, astronauts could eat only small pieces of dried food. But now astronauts are able to eat more everyday food like fruit, vegetables and ice cream.

　 Sleeping All the people in the ISS(国际空间站) have their own rooms. They have to tie (系) themselves to their beds, or they’ll fly away! That seems like a strange way to sleep, but astronauts say sleeping in space is really not too bad.

　 Exercising This is more important in space than on earth. Astronauts exercise on bikes and other machines(机器) for about two hours every day. That way, they can still be healthy when they get back home.

Having fun Astronauts can read books, play cards, listen to music or send e-mails to their friends and families when they aren’t working. Sometimes they just sit and look out of the window. It’s also much fun! .

Astronauts are hardworking whether in space or on the earth. Though the work sometimes is difficult, they are still interested in it and love the job. Many people think their lives are very interesting and their dream jobs are to be the astronauts.

Last month I got the chance to take part in an underwater research project in an area of the Gulf of Mexico called the Flower Gardens. A team of professional researchers, led by the scientist Dr Matt Phillips, was trying to learn more about the fish and different creatures that live in this part of the sea. The Flower Gardens are a long way from the shore (海岸) and we spent three days on a boat.

The team used a piece of underwater equipment(装备) called ROV to collect information. The ROV was great fun. It was controlled by a computer on the boat, and I was allowed to operate it a few times. However, the thing I enjoyed most was diving into the water. At first, I was quite scared---mainly because I couldn’t see land in any direction. But as soon as I jumped into the water, I wasn’t afraid any more. It was amazing to see the colorful fish swimming around and I could see all the ways to the Flower Gardens, which are almost 30 meters down.

I will never forget the Flower Gardens. The trip was like a holiday but I also learnt new things about science and research projects. It was a great chance and it has made me think about my goals in life. The experience will help me work harder to become a scientist.
