A group called the Education Arcade recently held a conference in Los Angeles to discuss the future of educational games．The Education Arcade brings together international game designers, publishers, teachers and policymakers．They say they want to lead a change in the way the world learns through computer and video games．

       The conference is part of the E-three, the Electronic Entertainment Exposition．This is a yearly trade show where companies show off new games and educational products．

       The Education Arcade started at the Massachusetts Institute of Technology, near Boston．Professors worked with the Microsoft Company to create what they called the Games-to-Teach Project．The group began to explore ways to use technology in teaching and learning．They worked with game designers to develop ideas about how mathematics and science could mix with game playing．The Education Arcade is the research part of this Games-to-Teach Project．

       The group recently announced that a “Games for Learning” statement would be placed on some products．Their goal is to help people find games that are fun but will also teach．The Education Arcade says it also wants to get businesses to produce more games that teach．

       The Entertainment Software Association says fifty percent of all Americans who are around six years old play computer and video games．Sales of such games in the United States grew eight percent last year, to seven thousand million dollars．The industry group says the average age of a game player is twenty-nine years old．And it says thirty-nine percent are women．

  Even plant can run a fever, especially when they’re under attack by insects or diseases. But unlike humans, plants can have their temperature taken from 3, 000 feet away - straight up. A decade ago, adopting the infrared（红外线）scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide（杀虫剂）spraying rather than rain poison on a whole field, which invariably includes plants that don’t have pest（害虫）problems.

　　Even better, Paley’s Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3, 000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a color-coded map showing where plants were running “fevers”. Farmers could then spot-spray, using 50 to 70 percent less pesticide than they otherwise would.

　　The bad news is that Paley’s company closed down in 1984, after only three years. Farmers resisted the new technology and long-term backers were hard to find. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt that technology works. “This technique can be used on 75 percent of agricultural land in the United States, ” says George Oerther of Texas A & M. Ray Jackson , who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only if Paley finds the financial backing which he failed to obtain 10 years ago.

1.Plants will emit an increased amount of heat when they are________.

　 A. sprayed with pesticides              B. facing an infrared scanner

　 C. in poor physical condition            D. exposed to excessive sun rays

2.In order to apply pesticide spraying precisely, we can use infrared scanning to____.

　 A. estimate the damage to the crops       B. measure the size of the affected area

　 C. draw a color -coded map                D. locate the problem area

3.Farmers can save a considerable amount of pesticide by________.

　 A. resorting to spot – spraying           B. consulting infrared scanning experts

　 C. transforming poisoned rain           D. detecting crop problems at an early stage

4.The application of infrared scanning technology to agriculture met with some difficulties due to ________.,

　 A. the lack of official support               B. its high cost

　 C. the lack of financial support              D. its failure to help increase production

Canadian scientists have found a method to help aging people get less forgetful by improving their cognitive（认知） abilities through well-designed training. Everyone experiences some degree of memory loss and cognitive decline as they get older. The decline usually becomes noticeable after 50, when people may find it slightly more difficult to focus on tasks, organize everyday jobs and remember how to do things in the right order.

A team of psychologists（心理学家）in Toronto created a strategy(策略) of cognitive training to help people preserve these abilities. "Our primary emphasis was on improving the use of general strategic abilities because they are particularly weak to the aging process," Dr. Donald Stuss, director of the study, said in a press release. The team examined 49 healthy older adults with normal cognitive decline. All of the participants were between the ages of 71 and 87. Over the course of 12 weeks, psychologists taught them methods to improve their strategic abilities. Afterwards, researchers saw a 15 to 40 percent improvement in the memories of all participants. “Over a period of six months their improvement not only maintained, but increased," said Dr. Gordon Winocur, coordinator of the study.

The 12-week course was broken up into three four-week sections, focusing on a different skill involved in strategic abilities: memory, goal management and psychosocial function.

The memory training emphasized how to preserve and recover information, while goal management focused on methods to lower the chance of memory slips. Psychosocial training was aimed at increasing the participants' confidence in their mental abilities.

“We wanted to develop a cognitive training program that would produce improvement over a relatively short period of time, so participants could benefit more on that while they're still functional and slow down the rate of decline," said Winocur. "If we can work with people in the early stages of cognitive decline, then we can slow down the rate of this decline and help them maintain a higher level of function for a longer period of time."
