Some researchers 21 more than 1,300 children in different grades for a year. They asked both the kids and their parents to estimate how many hours per week the kids spent watching TV and playing video games, and they 22 the children’s attention spans by 23 their schoolteachers. 24 studies have examined the effect of TV or video games on attention problems, but not both. By looking at video-game use 25 TV watching, these scientists were able to show for the first time that the two activities have a similar relationship 26 attention problems. Shawn Green, a psychologist at the University of Minnesota, points out that the study doesn’t distinguish between the type of 27 required to excel at a video game and that required to excel in school. “A child who is capable of playing a video game for hours 28 obviously does not have a 29 problem with paying attention,” says Green. “30 are they able to pay attention to a game but not in school? What expectancies have the games set up that aren’t being delivered in a school 31?” Modem TV shows are so exciting and fast paced that they make reading and schoolwork seem 32 by comparison, and the same may be true 33 video games, the study notes.“We weren’t able to break the games down by educational versus noneducational 34 nonvio-lent versus violent ,” says Swing ,35 that the impact that different types of games may have on at-tention is a ripe area for future research. 21.

The first computers — room-size behemoths — were referred to as “giant brains” or uelectronic brains , " in headlines and everyday speech. As computers improved and became capable of some tasks familiar to humans, like playing chess, the term used was “artificial intelligence”. DNA,it is said, is the original software. For the most part, the biological metaphor has long been just that — a simplifying analogy rather than a blueprint for how to do computing. Engineering, not biology, guided the pursuit of artificial intelligence. As Frederick Jelinek, a pioneer in speech recognition, put it, “airplanes don’t flap theirwings. “Yet the principles of biology are gaining ground as a tool in computing. The shift in thinking results from advances in neuroscience and computer science, and from the push of necessity.The physical limits of conventional computer designs are within sight — not today or tomorrow,but soon enough. Nanoscale circuits cannot shrink much further. Today’s chips are power hogs, running hot, which curbs how much of a chip’s circuitry can be used. These limits loom as demand is accelerating for computing capacity to make sense of a surge of new digital data from sensors, online commerce, social networks, video streams and corporate and government databases. To meet the challenge, without gobbling the world’s energy supply, a different approach will be needed. And biology, scientists say, promises to contribute more than metaphors. “Every time we look at this, biology provides a clue as to how we should pursue the frontiers of computing,” said John E. Kelly, the director of research at I. B. M. Dr. Kelly points to Watson, the question — answering computer that can play “Jeopardy!” and beat two human champions earlier this year. The I. B. M. ’s clever machine consumes 85,000 watts of electricity, while the human brain runs on just 20 watts. “Evolution figured this out, ” Dr. Kelly said. Several biologically inspired paths are being explored by computer scientists in universities and corporate laboratories worldwide. One project, a collaboration of computer scientists and neuroscientists begun three years ago, has been encouraging enough that in August it won a $21 million round of government financing. In recent months, the team has developed prototype “neurosynaptic” microprocessors ,or chips that operate more like neurons and synapses than like conventional semiconductors. 36.Paragraph 1 mainly tells. A.what the biological metaphor isB. how computers have improved C . when modem computing beganD. why DNA is the original software 37.Frederick Jelinek’s quotation implies that. A.technology is created by humans rather than by God B.airplanes differ from birds when using their wings C.computers can hardly match human brains D.biology can barely serve to explain computing 38.To meet growing demands computers need to be.
