Scientists have discovered a genetic defect that appears to cause deficit-hyperactivity disorder, more commonly known as hyperactivity. People afflicted with this disorder have trouble focusing their attention and controlling impulses, and tend to be rest-less and aggressive. The defect occurs in a gene that regulates the body's use of the thyroid hormone. This finding was made in continuing study organized by the National Institute of Diabetes and Digestive and Kidney Diseases in which 70 percent of children inheriting the gene were hyperactive while only 20 percent of the children not inheriting the gene were hyperactive. And although the researchers admit that this defective gene probably accounts for only a fraction of cases of hyperactivity, this discovery will allow doctors to spot newborn babies likely to have the disorder, and also to provide clues for its cause and treatment.

【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】______

Almost Human？ Scientists are racing to build the world’s first thinking robot .This is not science fiction：some
say they will have made it by the year 2020.Carol Packer repots.
Machines that walk，speak and feel are no longer science fiction.Kismet is the name of an android(机器人)which scientists have built at the Massachusetts Institute of Technology(MIT).Kismet is different from the tradition。al robot because it can show human emotions.Its eyes.ears and lips move to show when it feels happy.sad or bored.Kismet is one of the first of a new generation of androids—robots that 100k like human beings—which can imitate human feelings.Cog，another android invented by the MIT, imitates the action of a mother However,scientists admit that so far Cog has the mental ability of a two year old.
The optimists(乐观主义者)say that by the year 2020 we will have created humanoids(机器人)with brains similar to those of an adult human being.These robots will be designed to look like people to make them more attractive and easier to sell to the public.What kind of jobs will they do？ In the future，robots like Robonaut ，a humanoid invented by NASA，will be doing dangerous jobs，like repairing space stations They will also be doing more and more of the household work for US.In Japan，scientists are designing androids that will entertain US by dancing and playing the piano.
Some people worry about what the future holds：will robots become monsters(怪物)？Will people themselves become increasingly like robots？ Experts predict that more and more people will be wearing micro-computers，connected to the Internet，in the future.People will have micro-chips in various parts of their body，which will connect them to a wide variety of gadgets(小装置).Perhaps we should not exaggerate(夸大)the importance of technology，but one wonders whether , in years to come，we will still be falling in love，and whether we will still feel pain.Who knows？
第11题：Kismet is different from traditional robots because
A．it thinks for itself
B．it is not 1ike science fiction
C．it Can 100k after two-year—olds
D．it seems to have human feelings
