A. Control of Respiration
B. Basic tips for preserving cut flowers
C. Role of Respiration
D. Most Important Aspect of Flower Care
E. Need for Clean Water
F. Ways of Stopping Respiration

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 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.

On January 5th, students in our school visited Robot World, which we saw a great diversity of robots. It was amazed to find those robots could do a great number of things just as real people do, included playing chess, playing the piano and draw pictures. Besides, the robots were in different kinds and shapes, which makes us delighted. However, that excited me most was the show given by a group of robots.

I always wanted to be great scientist. I had a dream of discovering a new drug that would save hundreds of people’s life. Unfortunately, I was never very well at chemistry at school and the teacher was used to get angry with me. I decided to becoming an inventor and designed an amazing new product. My parents were encouraging, but told me to be a few more realistic. A few weeks late, I had an idea of designing a pen to write in water. In my disappointment, a friend of me pointed out that it was not a new invention.

B.		Why Mother’s Day Horrified, Ruined Its Own Mother Born of war, Mother’s Day grew to horrify its own mother, whose fight to fix the holiday “cost her everything, financially and physically.”

F.		Earth Day at 40: What Good Is It Now? After 40 years, outsourced activism is replacing traditional Earth Day activities, and green’s gone mainstream, experts say. So what’s the point?

以下是这些报道的简要内容介绍，请配对它们的标题。
小题1:Where did this most popular day for couples come from? And how does it come into beings, year after year? Noel Lenski, professor of the University of Colorado, said the lovers’ holiday traces its roots to raucous annual Roman festivals held every year on February 15 and remained wildly popular well into the fifth century A.D.
小题2:The first Earth Day in 1970 was a raucous, radical teach-in that helped spur clean-air, clean-water, and endangered species legislation in the United States. Now, 40 years later, Earth Day is every day, as the saying goes. The thing is, it’s also everyday- environmentalism that has become a routine with greenness as much a marketing tactic as a moral pursuit.
小题3:Some 242 million turkeys were raised in the U.S. in 2010 for slaughter, according to the U.S. Department of Agriculture’s National Agricultural Statistics Service. Last year’s birds were worth about U.S. $3.6 billion. Before the big dinner, debunk the myths, we need to know that the first “real” U.S. Thanksgiving wasn’t until the 1800s and get to the roots of Thanksgiving 2010.
小题4:Father’s Day traditionally takes a backseat to Mother’s Day, and, for the most part, dads are cool with that, experts say. Nevertheless, as traditional roles around the house gradually change, fathers are gaining more attention on their special day, at least as measured in the monetary value of gifts estimated to be given on June 19, 2011, when the holiday will be celebrated in dozens of countries.
小题5:Cookouts, fireworks, and, of course, a chance to wish Uncle Sam a big “happy birthday” —the day means summer in full swing across the United States and beyond. Besides the founders of the US, Fireworks, first authorized by Congress in 1777, are another legacy. More than 14,000 fireworks displays light up U.S. skies each year.
