3 . According to a research, more than 130 billion pounds of uneaten food go to waste in Laura’s county each year. That is about 30% of the yearly food supply (供应). It is a sad fact, especially when you consider how many families and homeless people are in hunger.

When Laura saw her school dining hall throw away food that was not eaten at all every day, she came up with an idea. She started a project to help her school dining hall to give away uneaten food to homeless shelters (避难所) in her community. In the past three years, the same protect has spread to other schools and some fast food restaurants throughout the city. The project is called Feed & Find, which has already fed thousands of people in her city.

How does it work? Through an app, Feed & Find matches local homeless shelters with school dining halls and restaurants that have uneaten food to provide. When dining halls or restaurants have uneaten food left, they can use the app to share the information about the food. A truck driver working for the project is then sent to pick it up and take it to a shelter.

Pretty cool, right? It’s not surprising that people in other cities have got in touch with Laura, to hoping that she could help develop similar projects for their communities.

Some people, however, dread the safety of the uneaten food. They think such food may not be clean enough. Still, this project is a clever way to help solve the problem of food waste and it helps those in need.

6 . The Great Fire of London started in the very early hours of September 1666. In four days it destroyed more than three-quarters of the old city, where most of the houses were wooden and close together. One hundred thousand people became homeless, but only a few lost their lives.

The fire started on Sunday morning in the house of the King’s baker(面包师)in Pudding Lane. The baker, with his wife and family, was able to get out through a window in the roof. A strong wind blew the fire from the bakery(面包房)into a small hotel next door. Then it spread quickly into Thames Street. That was the beginning.

By eight o’clock three hundred houses were on fire. On Monday nearly a kilometer of the city was burning along the River Thames. Tuesday was the worst day. The fire destroyed many well-known buildings, old St Paul’s and the Guildhall among them.

Samuel Pepys, the famous writer, wrote about the fire. People threw their things into the river. Many poor people stayed in their houses until the last moment. Birds fell out of the air because of the heat.

The fire stopped only when the King finally ordered people to destroy hundreds of buildings in the path of the fire. With nothing left to burn, the fire became weak and finally died out.

After the fire, Christopher Wren, the architect(建筑师), wanted a city with wider streets and fine new houses of stone. In fact, the streets are still narrow; but he did build more than fifty churches, among them new St Paul’s.

The fire caused great pain and loss, but after it London was a better place: a city for the future and not just of the past.

8 . Like a tired marriage, the relationship between libraries and publishers has long been dull. E-books, however, are causing heartache. Libraries know they need digital wares if they are to remain relevant, but many publishers are too cautious about piracy (盗版) and lost sales to cooperate. Among the big six, only Random House and Harper Collins license e-books with most libraries.

Publishers are wise to be nervous. Owners of e-readers are exactly the customers they need: book- lovers with money. If these people switch to borrowing e-books instead of buying them, what then? Electronic borrowing is awfully convenient. Unlike printed books, e-book files can be downloaded at home from digital libraries anytime. The files disappear from the device when they are due automatically. Awkwardly for publishers, buying an e-book costs more than renting one but offers little extra value.

E-lending is not simple, however. There are lots of different and often incompatible (不兼容的) e-book formats, devices and licenses. Most libraries use a company called OverDrive, which secures rights from publishers and provides e-books and audio files in every format. Yet publishers and libraries are worried by OverDrive’s global market dominance, as the company can control fees and conditions. Publishers were annoyed when OverDrive teamed up with Amazon, the world’s biggest online bookseller, last year. Owners of Amazon’s Kindle e-reader who want to borrow e-books from libraries are now redirected to Amazon’s website, where Amazon follows up library frequenters directly, letting them know they can “Buy this book” when the loan falls due.

According to Pew, an opinion researcher, library users are a perfect market for Amazon. Late last year Amazon introduced its Kindle Owners’ Lending Library, which lets its best customers borrow free one of thousands of popular books each month.

Library supporters argue that book borrowers are also book buyers and that libraries are vital spaces for readers to discover new works. Many were cheered by a recent Pew survey which found that more than half of Americans with library cards say they prefer to buy their e-books. So, publishers keep adjusting their lending arrangements in search of the right balance. Random House raised its licensing prices earlier this year, and Harper Collins limits libraries to lending its titles 26 times.

9 . Rocky Lyons was five years old when his mother, Kelly, was driving along the country road with him. He was asleep on the front seat of their truck, with his feet resting on her lap. As his mom drove carefully down the winding country road, she turned onto a narrow bridge. The truck hit a rock and slid off the road. She attempted to bring it back up onto the road by pressing hard on the gas pedal(踏板)and turning the steering wheel to the left. But Rocky's foot got caught between her leg and the steering wheel and she lost control of the truck.

The truck fell into a 20-foot ravine(峡谷). When it hit the bottom,Rocky woke up. “What happened, Mom?”   he asked. “Our wheels are pointing toward the sky.”

Kelly was seriously wounded and blinded by blood. “I’ll get you out, Mom, ” announced Rocky, who had surprisingly escaped injury. He climbed out from under Kelly, slid through the open window and tried to yank his mother out. But she didn’t move.

“Just let me sleep,” begged Kelly,who was out of consciousness(意识). Rocky insisted,“Mom, you can’t go to sleep.”

Rocky managed to push Kelly out of the truck and told her he’d climb up to the road and stop a car to get help. Fearing that no one would be able to see her little boy in the dark, Kelly refused to let him go alone. Instead they slowly moved up to the road. The pain was so great that Kelly wanted to give up, but Rocky wouldn’t let her.

Rocky kept repeating the inspirational phrase, “I know you can. I know you can.” When they finally reached the road, Rocky broke into tears seeing his mother’s torn face clearly for the first time. Waving his arms and shouting, “Please stop!” the boy stopped a truck. His mother was sent to hospital.

It took eight hours to rebuild Kelly’s face. She looks quite different today-she has a few scars but has recovered from her injuries.

Rocky’s heroics were big news. Everyone was surprised at this little boy’s power. “It’s not like I wanted it to happen,” the boy explained. “I just did what anyone would have done.” “If it weren’t for Rocky, I’d have died,” said his mother.
