【文章內(nèi)容簡(jiǎn)介】 ace is not only amazing but also dangerous. While working in space, spacemen are facing danger as well as success. Scientists have found out that the radiation（輻射） is the greatest danger to spacemen in space. When spacemen are working in space, they are in danger of the radiation from the sun and other stars, which is bad for their health. The harm of the radiation won39。t be found until their children even grandchildren are born. Some special medicine may work a little, but no really effective medicine has been found so far. Space rubbish is also thought to be a great danger to spacemen. It39。s reported that there were 9,000 manmade things flying in space. About 30% of these are satellites, 10% are spaceships, and the rest are space rubbish. An explosion（爆炸） in space in 1999 made a cloud of 300,000 fragments, each at least 4 mm in size. A small piece of these even knocked a spaceship window and caused some damage（損壞）. Scientists are watching and reporting any possible danger all the time. They are working to deal with space rubbish. Although space is really dangerous, it interests many people on the earth. In the near future, it may bee possible for people to spend a few days in a space hotel. We may even choose to leave the earth and live in space in a few years. So we should do something to help improve the space environment.（1） shows the manmade things in space in the correct way.

Perhaps it doesn39。t need to feel this way. Our experience of time can be possibly changed. By understanding the psychological （心理學(xué)的） processes behind our different experiences of time, we might be able to slow down time a little. One basic law of psychological time is that time seems to slow down when we39。re exposed （接觸） to new environments and experiences. The law is caused by the relationship between our experience of time and the amount of information our minds process. The more information our minds take in, the slower time seems to pass. It follows, then, that we have different experiences of time in different situations. In some situations, our life is full of new experiences. Our minds process a lot of information and time seems to slow down. In other situations, we have fewer new experiences and the world around us bees more and more familiar （熟悉的）. We bee insensitive to our experience, which means we process less information, and time seems to speed up. How can we slow down time? Here are two suggestions. Firstly, since we know that familiarity makes time pass faster, we can expose ourselves to as many new experiences as possible. We can give ourselves new challenges, meet new people, and expose our minds to new information, hobbies and skills. This will increase the amount of information our minds process and expand （增加） our experience of time. Secondly, and perhaps most effectively, we can give our whole attention to an experienceto what we are seeing, feeling, tasting, smelling or hearing. This means living through our senses rather than through our thoughts. For example, on the way home, focus your attention outside of yourself, instead of thinking about the problems you have to deal with. Look at the sky, or at the buildings you pass, traveling among them. This open attitude to your experiences
