小题1:______________
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 flower for a week or more without preservatives ( which contain biocides (杀虫剂) that kill bacterial 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 retain their freshness eight times longer when kept at 12℃ than when kept at 26℃. Keeping freshly harvested flowered at the right temperatures is probably the most important aspect of flower care.
小题3:_____________
The process by which flowers consume oxygen and produce carbon dioxide, called respiration (呼吸), supplies the energy the flower needs to give the flower its shape and color. 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 speed at which flowers die? By controlling respiration. How is respiration controlled? By controlling temperature, we know that respiration produces heat, but the reverse ( 反面 ) is also true. Thus by keeping 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, chlorine bleach ( 含氯漂白剂 ) can be used in small quantities. It is recommended that 15 drops of chlorine bleach be added to each liter of water. The water and solution （ 溶液 ）should also be replaced each day.

Thanks very much for your story. The plot is very touched. Now listen to me carefully. It’s very funny.

Well, he thought that it was belonged to the people in the house, but he paid no attention to it. He just pressed the bell, and the owners asked him in, and the dog went in, either. He greeted them with a smile and then he sat down, and a couple gave him a cup of coffee and some cookies. Well, the dog ate one of the cookies off the plate, and sat in his knee. The young man don’t want to seem rude, so he petted the dog gentle and continued talking to the couple. Anyway, gently when it was time to go, he thanked them and left. When the young man left, the woman called after him, “Excuse me, don’t forget to take your dog!
