The study focuses on ―fort food‖ and how it makes people feel. ―For me personally , food has always played a big role in my family, ‖ says Jordan Troisi, a graduate student at the University of Buffalo, and lead author on the study. The study came out of the research program of his coauthor Shira Gabriel. It has looked at nonhuman things that may affect human emotions. Some people reduce loneliness by bonding with their favorite TV show, building virtual relationships with a pop song singer or looking at pictures of loved ones. Troisi and Gabriel wondered if fort food could have the same effect by making people think of their nearest and dearest. In one experiment, in order to make participants feel lonely, the researchers had them write for six minutes about a fight with someone close to them. Others were given an emotionally neutral writing assignment. Then, some people in each group wrote about the experience of eating a fort food and others wrote about eating a new food. Finally , the researchers had participants plete questions about their levels of loneliness. Writing about a fight with a close person made people feel lonely. But people who were generally secure in their relationships would feel less lonely by writing about a fort food. ―We have found that fort foods are consistently associated with those close to us, ‖ says Troisi. ―Thinking about or consuming these foods later then serves as a reminder of those close others. ‖ In their essays on fort food, many people wrote about the experience of eating food with family and friends. In another experiment, eating chicken soup in the 天宇 考王職稱英語 、新東方 理工類 6 lab made people think more about relationships, but only if they considered chicken soup to be a fort food.

The Romans saw owls as omens of impending disaster and many ancient cultures viewed elephants as sacred animals endowed with special powers or attributes. 第五篇 Singing Alarms Could Save the Blind 【警報器救盲人】 If you cannot see, you may not be able to find your way out of a burning building — and that could be fatal. A pany in Leeds could change all that with directional sound alarms capable of guiding you to the exit. Sound Alert, a pany run by the University of Leeds, is installing the alarms in a residential home for blind people in Sommerset and a resource centre 天宇 考王職稱英語 、新東方 理工類 4 for the blind in Cumbria. The alarms produce a wide range of frequencies that enable the brain to determine where the sound is ing from. Deborah Withington of Sound Alert says that the alarms use most of the frequencies that can be heard by humans. It is a burst of white noise that people say sounds like static on the radio, she says. Its lifesaving potential is great. She conducted an experiment in which people were filmed by thermalimaging cameras trying to find their way out of3 a large smokefilled room. It took them nearly four minutes to find the door without a sound alarm, but only 15 seconds with one. Withington studies how the brain processes sounds at the university. She says that the source of a wide band of frequencies can be pinpointed more easily than the source of a narrow band. Alarms based on the same concept have already been installed on emergency vehicles. The alarms will also include rising or falling frequencies to indicate whether people should go up or down stairs. They were developed with the aid of a large grant from British Nuclear Fuels. 完形填空文章 _理工類 _B 級 第六篇 Car Thieves could Be Stopped Remotely【遠(yuǎn)程制止偷車賊】 Speeding off in a stolen car, the thief thinks he has got a great catch. But he is in a nasty surprise. The car is fitted with a remote immobilizer and a radio signal from a control center miles away will ensure that once the thief switches the engine off , he will not be able to start it again. For now, such devices are only available for fleets of trucks and specialist vehicles used on construction sites. But remote immobilization technology could soon start to trickle down to ordinary cars, and should be available to ordinary cars in the UK in two months. The idea goes like this. A control box fitted to the car incorporates a miniature cellphone, a microprocessor and memory, and a GPS satellite positioning receiver. If the car is stolen, a coded cellphone signal will tell the unit to block the vehicle‘s engine management system and prevent the engine being restarted. There are even plans for immobilizers that shut down vehicles on the move, though there are fears over the safety implications of such a system. In the UK, an array of technical fixes is already making life harder for car thieves. ―The pattern of vehicles crime has changed,‖ says Martyn Randall of Thatcham, a security research anization based in Berkshire that is funded in part by the motor insurance industry. He says it would only take him a few minutes to teach a novice how to steal a car, using a bare minimum of tools. But only if the car is more than 10 years old. Modern cars are a far tougher proposition, as their engine management puter will not allow them to start unless they receive a unique ID code beamed out by the ignition key. In the UK, technologies like this have helped achieve a 31 per cent drop in vehiclerelated crime since 1997. But determined criminals are still managing to find other ways to steal cars. Often
