    　　When you hear the word "roses", you would often assume that it is the red rose that is being referred to．Why is this so?Simply because there is no flower that has been respected and celebrated as much as the red rose．

    　　The modern red rose we are now familiar with was introduced to Europe from China in the 1800's．Evidence suggests that the red rose is nearly 35 million years old．The most commonly available roses belong to two broad categories：the Oriental species and their hybrids(杂交品种),and the European species and their hybrids．It is possible to grow a red rose anywhere in the world, if the species which it belongs to is selected according to climatic conditions．

    　　The red rose is a universal symbol of romance, passion and most importantly true love．Red roses are most often used as a strong expression of love, especially on special occasions like Saint Valentine's Day．Back in the 18th century, during a time when speaking aloud about one's heartfelt feelings was not in line with social customs, a special rose language was developed．This secret language acted as a system of communication between lovers who were forced to hide their true emotions by the society．Since then, the red rose has come to symbolize true love that will overcome all difficulties and the test of time．

    　　The red rose is also one of the most universal of all symbols．Apart from being the ultimate(最终的)symbol of love, red roses can also be used to celebrate courage, send out message of congratulations, and symbolize power．Scientific researches show that the red rose cure be used to cure some diseases．

    How Long Can People Live?

    　　She took up skating at age 85, made her first movie appearance at age 114, and held a concert in the neighborhood on her 121st birthday．

    　　Whe n it comes to long life, Jeanne Calment is the world’s recordholder．She lived to the ripe old age of 122．So is 122 the upper limit to the human life span(寿命)?If scientists come up with some sort of pill or diet that would slow aging, could we possibly make it to 150－or beyond?

    　　Researchers don’t entirely agree on the answers．“Calment lived to 122, so it wouldn’t surprise me if someone alive today reaches 130 or 135,”says Jerry Shay at the University of Texas．

    　　Steve Austad at the University of Texas agrees．“People can live much longer than we think,”he says．“Experts used to say that humans couldn’t live past 110．When Calment blew past that age, they raised the number to 120．So why can’t we go higher?”

    　　The trouble with guessing how old people can live to be is that it’s all just guessing．“Anyone can make up a number,”says Rich Miller at the University of Michigan．“Usually the scientist who picks the highest number gets his name in Time magazine．”

    　　Won’t new anti-aging techniques keep us alive for centuries?Any cure, says Miller, for aging would probably keep most of us kicking until about 120．Researchers are working on treatments that lengthen the life span of mice by 50 percent at most．So, if the average human life span is about 80 years, says Miller,“adding another 50 percent would get you to 120．”

    　　So what can we conclude from this little disagreement among the researchers?That life span is flexible(有弹性的)，but there is a limit, says George Martin of the University of Washington．“We can get flies to live 50 percent longer,”he says．“But a fly’s never going to live 150 years．”

    　　“Of course, if you became a new species(物种)，one that ages at a slower speed, that would be a different story,”he adds．

    　　Does Martin really believe that humans could evolve(进化)their way to longer life?“It’s pretty cool to think about it,”he says with a smile．
