高考英语二轮复习考前三个月专题一阅读理解细做模拟试题,题 型分类突破（七）主旨大意之段落大意题 主旨大意之段落大意题 A Do you know electricity can change the way we taste food ？Proving this fact is a revolutionary electric fork designed by Japanese researchers that can make any dish taste salty. According to Hiromi Nakamura ，a Post Doc Research Fellow at Tokyo’s Meiji University，the technology can be very useful for people on special diets.Patients with high blood pressure ， for instance ，can easily go on a low-salt diet and still enjoy delicious food.And with the fork ，there’s absolutely no risk of over-salting the ir food.Luckily ，the voltage(电压) is so small that there is no risk of electrocution(触电) either. The idea of adding electricity to food was first exposed as an experiment at the Computer Human Interaction Conference in Austin ，Texas ，in 2012.Nakamura and her t eam connected a wire to a 9-volt battery and passed it through a straw placed in a cup of sweet lemonade.Volunteers reported that the charged lemonade tasted “blander”，because the electricity created the taste of salt. Nakamura has improved the technology to be able to transfer an electric charge to food through forks and chopsticks.“The metallic part of the fork is one electrode(电极) ， and the handle is the other ，” Nakamura explained.“When you take a piece of food with the fork and put it in your mouth ，you connect the circuit.When you remove the fork from your mouth ， you disconnect the circuit.So it actually works as a switch.” Simon Klose ，host of food program Munchies ，who recently visited Nakamura to try out the fork himself ，called this form of “food hacking” one of the greatest eating experiences he’d ever had. “When I first heard of electric food，it sounded scary ，” he said.He later continued to use a charged fork to eat pieces of fried chicken ，an
