the green desert plant----cactus I bought a pot of cactus for hearing that its function of radiation protection. Having a computer, I spend most of my time sitting in front of it. It is impossible for us to touch the radiation, so I can feel little about the radiation. Only gazed at the computer screen for a long time can I have some uncomfortable feeling in my head and my eyes. At first, I bought a radiation protection glasses according to my friend’s recommend. However, I am not accustomed to wear the glasses and then I just left the glasses alone. When I went into my classmates’ dorm, I found that most of them have a pot of cactus on their desk. Some of the cactuses are very beautiful and attractive. It is wonderful to have a green plant close to the computer. So I do believe that it is necessary to buy some plant to absorb the radiation. There are so many green plants fit for protecting radiation, what had me made a decision to buy a cactus is that it is easy to keep. I don’t need to pay too much attention to take care of it. What’s more, it requires litter water and few skills to cultivate it so it is the most economy way to keep a plant. It is a real thing that I feel better after having a cactus beside the computer. When I feel tired after staring on the computer screen for a period, I will turn to the cactuses. At that time, I can feel a bright color in my eyes. It is so relax and comfortable to see the cactus. With the cactus, it is easy for me to have a good mood. I like its yellow flowers, just like a ball. There are some thorns. I have been pricked by its thorns. But I still love it so much. For I benefit more from it than harm. In my eyes, the cactus is a companion for me. It decorates my desk and my soul.
