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 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.
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.
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 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.
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.
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 liter of water. The water and solution should also be replaced each day.

How to Simplify Your Life
Less is more.This is why we say: reduce things by half instead of doubling them, get rid of junk instead of piling it up, relax instead of stressing, slow down instead of speeding up.Apply these principles in your everyday life in a conscious way.You will then find yourself well along on your journey to simplification.
1.___ _______.
When you concentrate on one task, you find you have energy that you didn't even know you had.Just imagine: you are at a fair and you have to carry two heavy pigs over 100 yards.If you keep grabbing one and then the other, it will take forever, because one of them will keep slipping out from under your arm and running off.But if you tie one pig in a place, pick up the other, gather all your strength and make a dash for the finish line, pause for a moment, run back and get the other one, and with great determination, carry the second pig to the finish line, then you can be sure of success.
2.__________.
The pressure at work is on the increase in all occupations.In the modern nuclear family, the expectations that formerly would have been shared among all the relatives are now concentrated on the individual partner.
If you have the feeling that 24 hours per day are not enough for all the things you need to do, then it’s not because the day has too few hours, but because you have too many activities.A simple fact that overloaded people often tend to forget.The solution is equally simple: refuse to accept so many work assignments in your private life or your working life.
3. ______.
“I can handle stress” is regarded as a positive statement in the world of work.People who can handle stress are given more and more to cope with — until one day they break.
Pay careful attention to the signs that tell you that you are under more stress than you can cope with.These signals came from various areas of life.You become ill, or your work efficiency decreases.
If you have any of these symptoms, change your life goals and decrease your tolerance of stress.Say quite openly, "I can't manage that."
4. _____.
"If only I were slimmer, more beautiful, richer, cleverer, then I would be happier." This is a dream that makes a lot of people ill, depressed, and unhappy.Life has its flaws, defects, comets, and edges.Only those who accept this reality can lead a really full life.
Of course there are activities in which errors are dangerous; driving a car, crossing the road.But life doesn't consist entirely of these things.In among them there is a lot of room for small and large mistakes.
5.___________.
Successful people all have their own places where they can withdraw in order to work.Find out which places improve your creativity.For me it's the train.When I know that I'm going to be traveling for four hours without phone calls and people knocking on my door, I find my mind is free and I can read or write complex articles.There can be problems working on the train, of course: if the person sitting opposite you keeps talking away, or if train trips make you tired (some people fall asleep after a few miles).
