Britain’s seed(种子) 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(植物的) gardens—will officially place 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, director Paul Smith said.
The seed bank is one of the largest and most diverse(多样的) 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 Asian elephants and important for growing bananas for human eating.
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 ten years 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 pressing 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 plant diversity.
For Kew's next goal—to collect a quarter of wild varieties（种类）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.What’s the final purpose of the Britain’s seed bank?

The Netherlands on Monday introduced its first-ever " intelligent bicycle , fitted with electronic devices to help bring clown the high accident rate among elderly cyclists in the bicycle-mad country．
Developed for the government by the Netherlands Organization for Applied Scientific Research （TNO） , the intelligent bicycle, runs on electricity．A commercial-available bicycle is expected to be on the market in the next two years and should sell for between 1, 700 to 3, 200 euros per bicycle．
The devices on the bike are linked through an onboard computer with a vibrating （震动的） warning system fitted in the bicycle's saddle and handlebars to warn cyclists of the coming danger.
The saddle vibrates when other cyclists approach from behind, while, the handlebars do the same when barriers appear ahead．
" Accidents often happen when cyclists look behind them or get a fright when they are passed at high speed," said Maurice Kwakkernaat, one of TNO's research scientists involved in the project．"The onboard system technology has already been at work in the car industry," he said．
'' More and more elderly people are using a bicycle, not only for short distances, but also for longer distances," Dutch Environment and Infrastructure Minister Melanie Schultz van Haegen told AFP．"This type of bicycle is truly needed in the Netherlands because it will help us bring down the number of elderly people who are injured every year and allow them to continue to enjoy cycling," she said．
In the Netherlands, bicycles outnumber the population of 17 million by at least one million and there are some 25,000 km of bicycle path in the country．Those statistics are set to grow as more and more people take to two-wheeled transport, leading to an increased risk of injury．
Last year, 184 cyclists died in the country, of which 124, or 67% , were older than 65, according to the Central Statistics Office．The year before, 200 cyclists died, the majority of victims also being elderly．
The current model weighs 25 kilograms but researchers are working on making the onboard systems smaller．The intelligent bicycle is aimed to ______．
| A．protect the environment |
| B．help reduce traffic pressure |
| C．popularize the use of bicycles |
| D．improve safety for elderly cyclists |
Which part of the intelligent bicycle will vibrate when other cyclists approach it from behind?
| A．The saddle． |
| B．The wheels． |
| C．The handlebars． |
| D．The onboard computer． |
We can learn from the passage that ______．
| A．the elderly ride bicycles wherever they go |
| B．the elderly are planning to give up cycling |
| C．the number of elderly cyclists is decreasing |
| D．the accident rate among elderly cyclists is high |
Which is the best title for the passage?
| A．A Test Bicycle |
| B．Elderly Cyclists |
| C．A Smart Bicycle |
| D．A Bicycle-mad Country |
All you have is what you bring with you
I've always felt a need to be prepared for whatever situation I've found myself in．
My mother once took me to a store when I was seven years old．She and I got to the checkout counter, and she realized she had forgotten a couple of things on her shopping list．She left me with the cart and ran off to get what she needed．
"I'll be right back．" she said．
She was gone just a few minutes, but in that time, I had loaded all the things on the belt and everything was rung up．I was left staring at the cashier, who was staling at me．"Do you have money for me, son?" she said．"I'll need to be paid．" -
I didn't realize she was just trying to amuse herself．So I stood there, ashamed and embarrassed．
By the time my mom returned, I was angry．"You left me here with no money! This lady asked me for the money, and I had nothing to give her I"
Now that I'm an adult, you'll never catch me with less than $200 in my wallet．I want to be prepared in case I need it．
I've always admired people who are over-prepared．In college, I had a classmate named Norman．One day he was giving a presentation on an overhead projector and in the middle of his talk, the light bulb （灯泡） on the projector blew out．We would have to wait ten minutes until someone found a new' projector．
"It's Okay．" he announced．"There's nothing to worry about．"
We watched him walk over to his bag and pull something out．He had brought along a spare bulb for the Overhead projector．Who could even think of that?
I often told my students, " When you go into the wilderness, the only thing you can depend on is what you take with you．" And essentially, the wilderness is anywhere but your home or office．So take money．Pack a light bulb．Be prepared．Why did the cashier ask a seven-year-old boy to pay for the purchases'?
| A．The boy was shopping by himself． |
| B．The boy's mother asked her to do so． |
| C．The cashier was playing a joke on him． |

Why was the boy angry with his mother?
| A．His mother left him alone． |
| B．He lost face in front of the cashier． |
| C．His mother forgot to buy something． |
| D．He had just quarreled with the cashier． |
Why did Norman bring a spare bulb with him?
| A．He was always well-prepared． |
| B．His presentation was about bulbs． |

Things Your Pilot Won't Tell You
You may not be getting the airline you paid for．
You may go to an airline website and buy a ticket, and get onto an airplane that has a similar name painted on it, but half the time, you're really on a regional （地方的） airline．The regionals aren't held to the same safety standards as the majors: their pilots aren't required to have as much training and experience, and the public doesn't know that．
—Captain at a major airline
If you're a nervous flier, book a morning flight．
The heating of the ground later causes bumpier （颠簸的） air, and it's much more likely to thunderstorm in the afternoon．
—Jerry Johnson , pilot, Los Angeles
The smoothest place to sit is often over or near the wing．
The bumpiest place to sit is in the back．If you're in the middle, you don't move as much．
—Patrick Smith, pilot, and author of Cockpit Confidential
Sit in the front if you want fresher air．
The general flow of air in any airplane is from front to back．So if you're really concerned about breathing the freshest possible air or not getting too hot, sit as close to the front as you can．Planes are generally warmest in the back．
—Tech pilot at a regional airline, Texas
You never know where the safest seat is．
There is no safest place to sit．In one accident, the people in the back are dead; in the next, it's the people up front．
—John Nance, aviation safety analyst and retired airline captain, Seattle
I've been struck by lightning twice．
Most pilots have．Airplanes are built to take it．You hear a big boom and see a big flash and that's it．You're not going to fall out of the sky．
—Charlotte, pilot for a regional earner,．North Carolina
People don't understand why they can't use their cell phones．
Well, what can happen is 12 people will decide to call someone just before landing, and I can get a false reading on my instruments saying that we are higher than we ideally are．
—Jim Tilmon, retired American Airlines pilot, PhoenixJerry Johnson advises nervous fliers to ______．
| A．sit in the back |
| B．fly in the morning |
| C．fly with major airlines |
| D．avoid flying in bad weather |

| B．make it difficult for pilots to control the plane |
| C．cause the instruments of the plane to break down |
| D．affect pilots' judgment about the height of the plane |
This summer, Monika Lutz’s life took an unusual turn. Instead of heading off to college, the high school graduate packed her bags for a Bengali jungle. Lutz, like a growing number of other young Americans, is taking a year off. Gap(间隔) years are quite common in Britain and Australia, but they are just beginning to catch on in the U.S. Lutz, who grew up in Boulder, Colo., has put together a 14-month schedule that includes helping deliver solar power to some communities in India and interning (实习) for a fashion designer in Shanghai---experiences that are worlds away from the lecture halls and university dormitories that await other students. “I could not be happier,” she says.
Why are students attracted to the gap-year concept? According to new survey data from Karl Haigler and Rae Nelson, education-policy experts and co-authors of The Gap-Year Advantage, the most common reason for this is to avoid burnout. “I felt like I was focused on college as a means to an end,” says Kelsi Morgan, an incoming Middlebury College freshman who spent last year interning for a judge in Tulsa, Okla., and teaching English at an orphanage in the Dominican Republic. The hope is that after a year out of the classroom, students will enter college more energized, focused and mature. That can be an advantage for colleges too. Robert Clagett, dean of admissions at Middlebury, did some research a few years ago and found that a single gap semester was the strongest predictor of academic success at his school.
Most experts recommend securing a spot in college before taking a gap year and warn against using the time off to lengthen your resume. “Most admissions folks can see right through that,” says Jim Jump, the academic dean of St. Christopher’s School in Richmond, Va. But for students like Lutz, who, after getting rejected from five Ivies, decided to take time off, a gap year can help focus interests. Lutz now plans to apply mostly to non-Ivies that have strong marketing programs. “This experience has really opened my eyes to the opportunities the world has to offer,” she says.
But at least one education expert doesn’t want schools spreading the gap-year message. In a study that followed 11,000 members of the high school class of 1992 for eight years after graduation, Stefanie DeLuca, a sociology professor at Johns Hopkins University, found that, all things being equal, those who delayed college by a year were 64% less likely to complete a bachelor’s degree than those who didn’t. DeLuca did not say whether these students voluntarily started college late, but at the very least, her work indicates that taking a gap year doesn’t guarantee success. “I’m not going to say that time off does not have benefits,” says DeLuca. “But I think we should not be so enthusiastic.”The students take gap years mainly because ______.
| A．they want to be more unusual |
| B．they want to refresh themselves |
| C．some experts advise them to do so |
| D．their parents think it good for them |
According to Lutz, the gap year has made her more ______.
| A．energetic | B．relaxed |
| C．practical | D．enthusiastic |
Stefanie DeLuca probably agrees that ______.
| A．students should think twice before taking gap years |
| B．taking gap years enables students to achieve success |
| C．schools should encourage their students to take gap years |
| D．taking gap years increases students’ chances of getting a good job |
What’s the author’s attitude towards gap years?
| A．Sceptical. | B．Positive. |
| C．Disapproving. | D．Objective. |
A bargain is something offered at a low and advantageous price. A more recent definition is: a bargain is a dirty trick to force money out of the pockets of silly and innocent people.
The cost of producing a new - for example - toothpaste would make 80p the proper price for it, so we will market it at £1.20. It is not a bad toothpaste, and as people like to try new things it will sell well to start with; but the attraction of novelty soon fades, so sales will fall. When that happens we will reduce the price to £1.15. And we will turn it into a bargain by printing 5p OFF all over it.
Sometimes it is not 5p OFF but 1p OFF. What breathtaking rudeness to advertise 1p OFF your soap or washing powder or whatever! Even the poorest old-age pensioner ought to regard this as an insult(侮辱), but he doesn’t. A bargain must not be missed. People say one has to have washing powder (or whatever) and one might as well buy it a penny cheaper.
The real danger starts when unnecessary things become ‘bargains’. Many people just cannot resist bargains. Provided they think they are getting a bargain they will buy clothes they will never wear or furniture they have no space for. Once I heard of a man who bought an electric saw as a bargain and cut off two of his fingers the next day. But he had no regrets: the saw had been truly cheap.
Quite a few people actually believe that they make money on such bargains. A lady once told me: “I’ve had a lucky day today. I bought a dress for £120, reduced from £400; and I bought a beautiful Persian carpet for £600, reduced from £900.” It will never occur to her that she has actually wasted £720. She feels as though she had made £580. She also feels, I am sure, that if she had more time for shopping, she could make a living out of it.
Some people buy in large quantities because it is cheaper. Once a couple bought enough sugar for their lifetime and the lifetime of their children and grandchildren. They thought it a bargain not to be missed. When the sugar arrived they didn’t know where to store it – until they realized that their toilet was a very spacious one. So that was where they piled up their sugar. Not only did their guests feel rather strange whenever they were offered sugar to put into their coffee, but the toilet became extremely sticky.
To offer bargains is a commercial trick to make the poor poorer. When greedy fools fall for this trick, it serves them right.Which word best describes the language style of the passage?
