Britain’s seed bank the only one in the world aiming to collect all of the planet’s wild plant species, has reached its goal of banking 10 percent by 2010．
The Millennium Seed Bank Project．run by Kew Gardens－one of the oldest botanical gardens－will officially deposit the 24,200th species on Thursday, a pink, wild banana from China．
More than 50 countries are now on board with Kew’s giant task but vast places of the globe, including India and Brazil, still need to join in and donate seeds, direcfor Paul Smith said．
The seed bank is one of the largest and most diverse in the world with more than 1.5 billion seeds．Its goal is to help protect the planet’s bio-diversity during a time of climate change．
The wild banana seed is under threat of extinction(灭绝)in southwest China from agricultural development．It is a vital food source for Asia．elephants and important for growing bananas for human consumption．
Stored at minus-20 degrees centigrade．So they can last for thousands of years, the seeds await the day that scientists hope never comes－when the species no longer exist in the wild．
It is a race against time, Smith said, because in the last decace alone, 20 plants held in the bank have already been wiped out in the wild．He estimates that between a third and a quarter will become extinct this century．
“It is urgent and it is happening now．An area, the size of England, is cleared of primary vegetation(植被)every year．”Smith said．
Because most of the world’s food and medicines come from nature,protecting wild plant species is quite important, scientists say．There are already many other seed banks safeguarding food crops, which only account for 0.6 percent of plany diversity．
For Kew’s next goal－to collect a quarter of wild varieties by 2020－the botanists need 10 million pounds a year, or a further 100 million pounds on top of the 40 million they have already been granted．

Suppose we built a robot(机器人)to explore the planet Mars．We provide the robot with seeing detectors(探测器)to keep it away from danger．It is powered entirely by the sun．Should we program the robot to be equally active at all times?No．The robot would be using up energy at a time when it was not receiving any．So we would probably program it to stop its activity at night and to wake up at dawn the next morning．
According to the evolutionary(进化的)theory of sleep, evolution equipped us with a regular pattern of sleeping and waking for the same reason．The theory does not deny(否认)that sleep provides some important restorative functions(恢复功能)．It merely says that evolution has programmed us to perform those functions at a time when activity would be inefficient and possibly dangerous．However, sleep protects us only from the sort of trouble we might walk into; it does not protect us from trouble that comes looking for us．So we sleep well when we are in a familiar, safe place, but we sleep lightly, if at all, when we fear that bears will nose into the tent．
The evolutionary theory explains the differences in sleep among creatures．Why do eats, for instance, sleep so much, while horses sleep so little?Surely cats do not need five times as much repair and restoration as horses do．But cats can afford to have long periods of inactivity because they spend little time eating and are unlikely to be attacked while they sleep．Horses must spend almost all their waking hours eating, because what they eat is very low in energy value．Moreover, they cannot afford to sleep too long or too deeply, because their survival(生存)depends on their ability to run away from attackers．

Several years ago, my parents, my wife, my son and I ate at one of those restaurants where the menu is written on a blackboard．After a wonderful dinner, the waiter set the check in the middle of the table．That’s when it happened：my father did not reach for the check．
Conversation continued．Finally I realized that I should pick up the check!After hundreds of restaurant meals with my parents, after a lifetime of thinking of my father as the one with dollars, it had all changed．I reached for the check, and my view of myself suddenly changed．I was an adult．I was no longer a kid．
Some people mark off(区分)their lives in years, I measure mine in small events．I didn’t become a young man at a particular age, like 16, but rather when a kid who wandered in the streets called me “mister．” These events in my life are called “milestones”(里程碑)
There have been other milestones．The cops(policemen)of my youth always seemed big, even huge, and of course they were older than I was．Then one day they were suddenly realized that all the football players in the game I was watching were younger than I was．They were just big kids．With that milestone gone was the dream that someday, maybe I, too, could be a football player．Without ever having reached the hill, I was over it．
I never thought that I would fall asleep in front of the TV set as my father did．Now it’s what I do best．I never thought that I would go to the beach and not swim, yet I spent all of August at the shore and never once went into the ocean．I never thought that I would appreciate opera, but now the combination of voice and orchestra attract me．I never thought that I would prefer to stay home in the evenings, but now I find myself passing up parties．I used to think that people who watched birds were strange, but this summer I fond myself watching them, and maybe I’ll get a book on the subject．I feel a strong desire for a religious belief that I never thought I’d want, feel close to my ancestors(祖先)long gone, and echo my father in arguments with my son．I still lose…
One day I bought a house．One day－what a day!–I became a father, and not too long after that I picked up the check for my own father．I thought then it was a milestone for me．One day, when I was a little older, I realized it was one for him, too, another milestone．

It was at least two months before Christmas when nine-year-old Almie Rose told her father and me that she wanted a new bicycle．As Christmas drew near, her desire for a bicycle seemed to fade, or so we thought．We bought the latest rages．Baby-Sitter’s Club dolls, and a doll house．Then, much to our surprise, on December 23rd, she said that she “really wanted a bike more than anything else．”
It was just too late, what will all the details of preparing Christmas dinner and buying last-minute gifts, to take the time to select the “right bike” for our little girl．So here we were－Christmas Eve around 9∶00 p. m., with Almie and her six-year-old brother, Dylan, nested snug in their beds．Now we could only think of the bicycle and the disappointment of our child．“What if the bicycle out of clay(a kind of earth)and write a note that she could trade the clay model in for a real bike?” her dad asked．“This is an expensive item and she is ‘such a big girl,’ and it would be much better for her to pick it out．”So he spent the next four hours painstakingly working with clay to make a tiny bike．
On Christmas morning, we were excited for Almie to open the little heart-shaped package with the beautiful red and white clay bike and the note．Finally, she opened it and read the note aloud．“Does this mean that I trade in this bike that Daddy made me for a real one?”Beaming, I said,“Yes．”Almie had tears in her eyes when she replied,“I could never trade in this beautiful bicycle that Daddy made me．I’d rather keep this than get a real bike．”At that moment, we would have moved heaven and earth to buy every bicycle on the planet!
