Keeping Cut Flowers
1 While everybody enjoys fresh cut flowers around his/her 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.
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 lon-ger when kept at 12℃ than when kept at 26℃. Keeping freshly harvested flowers at the right tem- peratures 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 at-tract 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 (二氧化碳). 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 ot heat relative to the mass of the flower is very high. Respiration also brings about the eventualdeath 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 respi-ration controlled? By controlling temperature. We know that respiration produces heat, but the re-verse(相反的过程) 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 (漂白剂) can be used in small quantities. It is recommended that 15 drops of chlorine bleach (at 4% solution) be add-ed to each litre of water. The water and solution should also be replaced each day.

Car Crime
1、 A million motorists leave their cars filled up with petrol and with the keys in the ignition every cars are sitting in petrol stations while drivers pay for their Automobile Association(AA)has discovered that cars are left unattended for an average three minutes and sometimes longer as drivers buy drinks，sweets，cigarettes and other consumer payment of credit cards becoming more and more common，it is not unusual for a driver to be out of his car for as long as six minutes，providing the car theft with a golden opportunity.
2、 For more than ten years there has been a big rise in car crime than in most other types of crimes. An average of more than two cars a minute are broken into or stolen in the UK. Car crime accounts for almost a third of all reported offenses with no signs that the trend is slowing down.
3、 Although there are highly professional criminals involved in car theft, almost 90 percent of car theft is committed by the opportunists. Amateur thieves are aided by our own carelessness. The AA recommends locking up whenever you leave the car and for however short a period. A partially open sunroof or window is a further come-on to thieves.
4、 There are many other traps to avoid. The AA has found little awareness among drivers about safe parking. Most motorists questioned made no efforts to avoid parking in quiet spots-just the places thieves' love. The AA advises,drives to park in places with people around-thieves don't like audiences.
