17．The ancient Egyptians appeared to be among the first early civilizations to learn how to grow roses．In 1888，at Hawara in the El Faiyum area of Egypt，two-thousand-year-old roses were found in ancient tombs．The discovery suggested roses were an important part of the complex burial ceremony which took place when an important person died．The roses found in the tombs are thought by modern experts to be the oldest preserved flowers ever found in the world．They must have been cut and dried before flowering so that they would remain undamaged．Over the centuries，the roses had shrunk and became tight balls，but on careful examination it was discovered that the petals （花瓣） themselves were hardly damaged．
Egypt's skill in mass-cultivation（大面积栽培）of roses in early times led to the flowers becoming an important export product．At the height of the Roman Empire，Egypt exported large quantities of roses to the Roman courts．Wealthy Romans loved the beautiful colors and sweet smells of roses．So the Romans attempted to grow their own roses and they eventually mastered the art of mass cultivation．Egypt then decided to concentrate on growing grain instead of roses，so grain soon took over as the number-one agricultural product of Egypt．
Roses were appreciated in other early civilizations too，including Greece and Persia．They are a decorative feature on coins，sculpture，and vases dating back thousands of years．There is also evidence that roses were highly valued by the Chinese who believed that the flowers could be used to help treat a wide range of illnesses，from toothache to skin and chest diseases．
In the modern world，the rose has not lost its popularity as the"Queen of Flowers"-the name given to it by the Greek poetess Sappho．Even today more roses are sold than any other flower．Modern techniques have enabled people to create ever more beautiful roses．Transportation by air makes it possible to grow roses in countries with favorable climates and sell them within twenty-four hours in profitable markets all over the world．Tons of roses are transported this way every week．Roses from Ecuador，a country in northern South America，can be bought in Holland，even though that country itself has a huge rose-growing business．

5．The light from the campfire brightened the darkness，but it could not prevent the damp cold of Dennis's Swamp （沼泽地） creeping into their bones．It was a strange place．Martin and Tom wished that they had not accepted Jack's dare．They liked camping，but not near this swamp．
"So，"Martin asked as they sat watching the hot coals．"How did this place get its name？"
"Are you sure you want to hear it？It's a scary story，"warned Jack．
"Of course!"cried out Tom．"If there were anything to be scared of，you wouldn't have chosen this place!"
"Ok，but don't say I didn't warn you，"said Jack，and he began this tale．
"Way back in time，a man called Dennis tried to start a farm here．He built that cottage over there to live in．In those days，the area looked quite different--it was covered with tall trees and the swamp was a crystal-clear river．After three hard years，Dennis had cleared several fields and planted crops．He was so proud of his success that he refused to listen to advice．
"‘You are clearing too much land，warned one old man．‘The land is a living thing．It will hit back at you if you abuse it．
"Silly fool，said Dennis to himself．If I clear more land，I can grow more crops．I'll become wealthier．He's just jealous!"
"Dennis continued to chop down trees．Small animals that relied on them for food and shelter were destroyed．He was so eager to expand his farm that he did not notice the river flowing slowly towards his door．He did not notice salt seeping to the surface of the land．He did not notice swamp plants choking all the native plants．"
"What happened？"Martin asked．It was growing colder．He trembled，twisting his body closer to the fire．
"The land hit back--just as the old man warned，"Jack shrugged．"Dennis disappeared．Old folks around here believe that swamp plants moved up from the river and dragged him underwater．His body was never found．"
"What a stupid story，"laughed Tom．"Plants can't …"Before he had finished speaking，he screamed and fainted（晕倒）．The other two boys jumped up with fright，staring at Tom．Suddenly，they burst out laughing．Some green swamp ivy （常春藤） had covered Tom's face．It was a while before Tom could appreciate the joke．
