Passage 19

(08·宁夏、海南、全国ⅠB篇)

More than 10 years ago, it was difficult to buy a tasty pineapple．The fruits that made it to the UK were green on the outside and, more often than not, hard with an unpleasant taste within．Then in 1996, the Del Monte Gold pineapple produced in Hawaii first hit our shelves．

The new type of pineapple looked more yellowy-gold than green．It was slightly softer on the outside and had a lot of juice inside．But the most important thing about this new type of pineapple was that it was twice as sweet as the hit-and-miss pineapples we had known．In no time,the Del Monte Gold took the market by storm, rapidly becoming the world’s best-selling pineapple variety,and delivering natural levels of sweetness in the mouth,up until then only found in tinned pineapple．

In nutrition (营养) it was all good news too．This nice-tasting pineapple contained four times more vitamin C(维生素C)than the old green variety．Nutritionists said that it was not only full of vitamins,but also good against some diseases．People were understandably eager to be able to buy this wonderful fruit．The new type of pineapple was selling fast,and the Del Monte Gold pineapple rapidly became a fixture in the shopping basket of the healthy eater．

Seeing the growing market for its winning pineapple, Del Monte tried to keep the market to itself．But other fruit companies developed similar pineapples. Del Monte turned to law for help,but failed．Those companies argued successfully that Del Monte’s attempts to keep the golden pineapple for itself were just a way to knock them out of the market．

Passage 18

(09·全国ⅡC篇)

GUATEMALA CITY (Reuters) – A fish that lives in mangrove swamps(红树沼泽)across the Americas can live out of water for months at a time, similar to how animals adapted(适应)to land millions of years ago, a new study shows. 　

The Magrove Rivulus, a type of small killifish, lives in small pools of water in a certain type of empty nut or even old beer cans in the mangrove swamps of Belize, the United States and Brazil. When their living place dries up, they live on the land in logs(圆木)，said Scott Taylor, a researcher at the Brevard Endangered Lands Program in Florida.　

The fish, whose scientific name is Rivulus marmoratus, can grow as large as three inches. They group together in logs and breathe air through their skin until they can find water again.　

The new scientific discovery came after a trip to Belize.　

　“We kicked over a log and the fish just came crowding out,” Taylor told Reuters in neighboring Guatgemala by telephone. He said he will make his study on the fish known to the public in an American magazine early next year.　

In lab tests, Taylor said he found the fish can live up to 66 days out of water without eating.　

Some other fish can live out of water for a short period of time. The walking catfish found in Southeast Asia can stay on land for hours at time, while lungfish found in Australia, Africa and South America can live out of water, but only in an inactive state. But no other known fish can be out of water as long as the Mangrove Rivulus and remain active, according to Patricia Wright, a biologist at Canada’s University of Guelph.　

Further studies of the fish may tell how animals changed over time.　

　“These animals live in conditions similar to those that existed millions of years ago, when animals began making the transition(过渡)from water onto land,” Wright said.
