Ray Travers sat back at the large desk, and looked around his plush（豪华的）office. He was tired
Ray's eyes stopped at a painting on the wall. It was a gift given by an old friend，Bull，as a farewell gift when he left his hometown He recalled the life spent in that small town; pleasant times. The many hours he spent talking to his good friend, and the tales he was told about hunting in the Africa of old.
Memories flowed back more than ten years; he remembered how he enjoyed hearing about the wonderful hunting，and how he wished he could have shared those times.
Ray opened his desk drawer and brought out a wooden box. He opened the lid and exposed a work of art，a hand-made hunting knife. This was a gift from Bull，given to Ray more than 20 years ago. It was one of the first knives Bull had made, and Ray had called it "Zambezi"，the river where Bull had been so many times.
He closed the box and sat upright at his desk；he was driving himself hard, and deserved a break. Things were going well with the business，everything running smoothly. He could afford a week off！
He went back home. A week in the hometown would be like going back in history. "Man, it's going to be good,”Ray said aloud，as he turned onto the highway and watched the city lights fast disappearing，as he looked in the rearview mirror. The powerful car going its way through the night, headlights piercing（穿透）the darkness. Memories danced through the man's mind. Memories of good times，when he knew what it was to relax, to talk，and to really visit.
Slowly entering town he looked around. Ray sat in his car, looking at the old building，smiling. Inside it was almost as though it was the same people as 15 years ago.

While everybody enjoys fresh cut flowers around his house, few people know how to keep them for as long as possible. This may be done by keeping in mind a few simple facts. The key to keeping fresh cut flowers for a week or more without floral preservatives(which contain biocides that kill bacteria and fungus) is to keep the water fresh and the stems free of air pockets so they can continue to draw up water.
【小题2】
An important thing to remember about cut flowers is that they are sensitive to temperature. For example, studies have shown that cut carnations(康乃馨) retain their freshness eight times longer when kept at 12℃ than when kept at 26℃. Keeping freshly harvested flowers at the right temperatures is probably the most important aspect of flower care.
【小题3】
Flowers are not intended by nature to live very long. Their biological purpose is simply to attract birds or insects, such as bees, for pollination (授粉). After that, they quickly dry up and die. The process by which flowers consume oxygen and produce carbon dioxide, called respiration (呼吸), generates the energy the flower needs to give the flower its shape and colour. The making of seeds also depends on this energy. While all living things respire, flowers have a high level of respiration. A result of all this respiration is heat, and for flowers the level of heat relative to the mass of the flower is very high. Respiration also brings about the eventual death of the flower. Thus the greater the level of respiration, the sooner the flower dies.
【小题4】
How, then, to control the rate at which flowers die? By controlling respiration. How is respiration controlled? By controlling temperature. We know that respiration produces heat, but the reverse is also true. Thus by maintaining low temperatures, respiration is reduced and the cut flower will age more slowly.
【小题5】
Another vital factor in keeping cut flowers is the quality of the water in which they are placed. Flowers find it difficult to “drink” water that is dirty or otherwise polluted. Even when water looks and smells clean, it almost certainly contains harmful substances that can endanger the flowers. To rid the water of these unwanted substances, household chlorine bleach (含氯漂白剂) can be used in small quantities. It is recommended that 15 drops of chlorine bleach(at 4% solution) be added to each litre of water. The water and solution should also be replaced each day.
