【C1】______ nearly a hundred years of powered flight, scientists are still trying to figure out how birds fly.

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】______

I was just a boy when my father brought me to Harlem for the first time, almost 50 years ago. We stayed at the Hotel Theresa, a grand brick structure at 125th Street and Seventh Avenue. Once, in the hotel restaurant, my father pointed out Joe Louis. He even got Mr Brown, the hotel manager, to introduce me to him, a bit paunchy but still the champ as far as I was concerned.

Much has changed since then. Business and real estate are booming. Some say a new renaissance is under way. Others decry what they see as outside forces running roughshod over the old Harlem. New York meant Harlem to me, and as a young man I visited it whenever I could. But many of my old haunts are gone. The Theresa shut down in 1966. National chains that once ignored Harlem now anticipate yuppie money and want pieces of this prime Manhattan real estate. So here I am on a hot August afternoon, sitting in a Starbucks that two years ago opened a block away from the Theresa, snatching at memories between sips of high-priced coffee. I am about to open up a piece of the old Harlem -- the New York Amsterdam News -- when a tourist asking directions to Sylvia's, a prominent Harlem restaurant, penetrates my daydreaming. He's carrying a book: Touring Historic Harlem. History. I miss Mr Michaux's bookstore, his House of Common Sense, which was across from the Theresa. He had a big billboard out front with brown and black faces painted on it that said in large letters: "World History Book Outlet on 2,000,000,000 Africans and Nonwhite Peoples." An ugly state office building has swallowed that space. I miss speaker like Carlos Cooks, who was always on the southwest corner of 125th and Seventh, urging listeners to support' Africa. Harlem's powerful political electricity seems unplugged -- although the streets are still energized, especially by West African immigrants. Hard-working southern newcomers formed the bulk of the community back in the 1920s and '30s, when Harlem renaissance artists, writers, and intellectuals gave it a glitter and renown that made it the capital of black America. From Harlem, W. E. B. DuBois, Langston Hughes, Paul Robeson, Zora Neal Hurston, and others helped power America's cultural influence around the world. By the 1970s and '80s drugs and crime had ravaged parts of the community. And the life expectancy for men in Harlem was less than that of men in Bangladesh. Harlem had become a symbol of the dangers of inner-city life. Now, you want to shout "Lookin' good!" at this place that has been neglected for so long. Crowds push into Harlem USA, a new shopping centre on 125th, where a Disney store shares space with HMV Records, the New York Sports Club, and a nine-screen Magic Johnson theatre complex. Nearby, a Rite Aid drugstore also opened. Maybe part of the reason Harlem seems to be undergoing a rebirth is that it is finally getting what most people take for granted. Harlem is also part of an "empowerment zone" a federal designation aimed at fostering economic growth that will bring over half a billion in federal, state, and local dollars. Just the shells of once elegant old brownstones now can cost several hundred thousand dollars. Rents are skyrocketing. An improved economy, tougher law enforcement, and community efforts against drugs have contributed to a 60 percent drop in crime since 1993. At the beginning the author seems to indicate that Harlem A．has remained unchanged all these years. B．has undergone drastic changes. C．has become the capital of Black America. D．has remained a symbol of the dangers of inner-city life.
