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 Japane rearchers that can make any dish
taste salty.
According to Hiromi Nakamura，a Post Doc Rearch Fellow at Tokyo’s Meiji University，the technology can be very uful 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 expod 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 pasd it through a straw placed in a cup of sweet lemonade.Volunteers reported that the charged lemonade tasted “blander”，becau 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 Klo，host of food program Munchies，who recently visited Nakamura to try out the fork himlf，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 u a charged fork to eat pieces of fried chicken，and found that the saltiness considerably incread as the electricity was connected.
Nakamura has been eating “electric” food for the past three to four years in an attempt to understand it better.“For me，‘food hacking’ is about strengthening or weakening real food，” she said.“It may em like we’re cooking but we’re actually working on the human ns.”

In anticipation(预料) of an extraordinary visit，the streets and buildings of Havana，Cuba，were cleaned and painted by dozens of workers.What was the occasion?
For the first time in nearly 90 years，a sitting United States president was coming to Cuba，an island nation 90 miles south of Florida.On Sunday，President Barack Obama，joined by his family，stepped off Air Force One and onto a rainy runway，where Cuban dignitaries(高官) eagerly awaited him.“It’s wonderful to
