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 as well as success.

Scientists have found out that radiation(辐射) 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(危害) 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(垃圾) 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 satellites, 10% are spaceships, and the rest are space junk. An explosion(爆炸) in 1996 made a cloud of 300,000.fragments, each at least 4mm 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 m space in a few years. So we should care for space and do something to help improve the space environment.

My father woke me up early one summer morning when I was fourteen and announced: “Get up, you're going with me to cut the grass in the garden. ”

  The idea that my father thought I was old enough to help him in his business made me feel proud and excited. From sunup to sundown, my father, my younger brother and I worked in the large garden. By the end of the day I was too tired to say a word but I felt good. This was my first time to help my father in his business. I got $ 6 for my work that day.

  One day my father found some leaves I had missed and pulled me aside. “Take away these leaves! ”he said, “and don't make me have to tell you to do it again.” The message was clear. Today I value(珍视)the importance of doing a job well the first time. It will never fail to impress(给……留下印象) the person you are working for.

  After two years, my father told me and my brother that he felt we were old enough to cut the grass by ourselves. Every Saturday during my last two years of high school, we set off early in the morning with the same strong wish we had gained while working under our father.

  Looking after the garden was neither exciting nor high paying, but that didn't matter. It taught me that any job was a good job and that whatever I was paid was more than I had before.

  A newspaper reporter once asked me how someone could possibly live with hard work and low pay. “If you're only thinking about hard work and money, you probably don't want to do any better than you are doing.” I answered. In every job, from cutting the grass to washing dishes, I've learned much. I've learned something that helps me in my next job.

  If you work hard enough, you can learn from any job you do.
