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 their 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 team 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, and found that the saltiness considerably increased 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 seem like we’re cooking but we’re actually working on the human senses.”

1.The electric fork may benefit people who__________.

A. need to go on a diet B. have high blood pressure

C. prefer food free of salt D. show interest in tasty food

2. Paragraph 4 mainly tells us _________.

A. how the electric fork works

B. what makes the circuit connected

C. how the technology was improved

D. why the electric fork was invented

3. From the passage, we learn that the electric fork______.

A. creates virtual taste B. changes people’s diets

C. helps cure diseases D. replaces salt in cooking

If you put all the books you own on the street outside your house, you might expect them to disappear immediately. But one man, Hernando Guanlao in Manila, tried it and found that his collections grew.

He’s a lovely man in his early 60s, with one ever-lasting love—books. They’re his pride and joy, because, whether he likes it or not, they seem to be taking over his house. Guanlao has set up a “library” outside his home in central Manila. Readers can take as many books as they want, for as long as they want. As Guanlao says, “The only rule is that there are no rules.”

You might consider it would end very quickly. But in fact, in the 12 years he’s been running his library. He’s found that his collection has grown rather than become smaller, as more and more people help the activity. “It seems to me that the books are speaking to me,” he says with a smile, “The books are telling me they want to be read.”

Guanlao started his library in 2000, shortly after the death of his parents. He was looking for something to honor their memory, and that was when he hit upon the idea of promoting the reading habit passed on to him from his parents. So he put the books outside the door of his house to see if anyone wanted to borrow them. They did, and they brought the books back with others to add to the collection. The library was born. The library is not advertised, but somehow, every day, a steady stream of people find their way there.

To help the poorest communities in Manila, Guanlao doesn’t wait for them to find him on his “book bike”. He wants to set up a “book boat”, traveling around the islands of Sulu and Basilan. As we sat outside Hernando Guanlao’s house in the midday sun, watching people look through his collection, he thought it was worth spending all his time.

4.What caused Guanlao to have the idea of setting up a library?

In this influential work about the surprising divide between children and the outdoors, child supporter expert Richard Louv directly links the lack of nature in the lives of today’s wired generation---he calls it nature-deficit(赤字)----to some of the most disturbing childhood trends, such as the rises in obesity, attention disorders, and depression.

Last Child in the Woods is the first book to bring together a new and growing body of research indicating that direct exposure to nature is essential for healthy childhood development and for the physical and emotional health of children and adults. More than just raising an alarm, Louv offers practical solutions and simple ways to heal the broken bond---and many are right in our own backyard.

This new edition reflects the great changes that have taken place since the book was originally published. It includes:

·100 actions you can take to create change in your community, school, and family.

·35 discussion points to inspire people of all ages to talk about the importance of nature in their lives.

·A new progress report by the author about the growing Leave No Child Inside movement.

·New and updated research confirming that direct exposure to nature is essential for the physical and emotional health of children and adults

Last Child in the Woods: Saving our Children from Nature Deficit Disorder has promoted a national dialogue among educators, health professional, parents, developers and conservationists. This is a book that will change the way you think about the future of your children.
