Farmers&39; Markets
Charlotte Hollins knows she faces a battle. The 23-year-old British farmer and her 21-year-old brother Ben are fighting to save the farm from developers that their father worked on since he was14. __________ (46)
"You don&39;t often get a day off. Supermarkets put a lot of pressure on farmers to keep prices down. With fewer people working on farms it can be isolating," she said. "There is a high rate of suicide and farming will never make you rich!"
Oliver Robinson,25, grew up on a farm in Yorkshire. __________ (47) "I&39;m sure dad hoped I&39;d stay," he said. "I guess it&39;s a nice, straightforward life, but it doesn&39;t appeal. For young,ambitious people, farm life would be a hard world." For Robinson, farming doesn&39;t offer much "in terms of money or life style". Hollins agrees that economics stops people from pursuing farming rewards: "providing for a vital human need, while working outdoors with nature".
Farming is a big political issue in the UK. __________ (48) The 2001 foot and mouth crisis closed thousands of farms, stopped meat exports, and raised public consciousness of troubles in UK farming.
Jamie Oliver&39;s 2005 campaign to get children to eat healthily also highlighted the issue. This national concern spells (带来) hope for farmers competing with powerful supermarkets.__________ (49)
"I started going to Farmers&39; Markets in direct defiance (貌视) of the big supermarkets.__________ (50) It&39;s terrible," said Londoner Michael Samson.

关系表达式x＜5的相反表达式为_____
Researchers have learned that the slapping noise pigeons make when they suddenly take off is the sound of super charged lift. They call it the "clap fling" effect.
Here at SRI International scientists try to duplicate the pigeons' thrust. A flashing strobe reveals the secret.
Scott Stanford, a scientist at SRI, says, You re looking at the clap fling effect, where the two wings will come together and peel apart 【C2】______ each other, thus augmenting lift 【C3】______ drawing air from the top to the bottom. "
This mechanical bug won't get off the ground. 【C4】______ its flapping wings demonstrate a potential propulsion system for robotic birds: man-made rubbery muscle.
Roy Kornbluh works at SRI. "There, I'm turning the voltage on and off, and you can see when the voltage is on, the material is larger 【C5】______ when the voltage is off."
Super computers show high-speed airflows over supersonic aircraft.
But scientists have only begun to see how air flows 【C6】______ really low speeds.
Professor Max Platzer of the Naval Postgraduate School, says, "The flapping wing is generating a thrust, this way, this is the basic physics of the phenomenon."
It's pelicans--not pigeons--the Navy is looking at. The Navy is looking at the smooth easy flight of pelicans low over water--called "ground effect." Researchers at the Naval Postgraduate School are trying to imitate the pelican's efficiency.
Assistant Professor Kevin Jones of the Naval Postgraduate School says, " 【C7】______ flapping the wings, symmetrically, we're 【C8】______ effect imitating ground effect. We now have the same feature a bird sees when it's flying, over a ground plane."
An electric motor drives the flapping wings. Researchers here are working 【C9】______ ways to beam power to the tiny bird.
David Jenn of the Naval Postgraduate School says, "There's no battery inside of here, so we're going to set this inside the radar beam, and the energy is extracted from the radar beam and will be used to propel the motor."
Scientists are learning it's one thing to build an airplane, 【C10】______ quite another to build a bird.
【C1】______
