Even at school there had been an unhealthy competition between George and Richard.

    “I'll be the first millionaire in Clifford!” Richard Pike used to say.

    “And you'll sorry you knew me,” George would reply “because I'll be the best lawyer in town!”

    George never did become a lawyer and Richard Pike never made any money. Instead both men opened bookshops on opposite sides of Clifford High Street. It was hard to make money from books, which made the competition between them worse.

    Now with only one bookshop in town, business was better for George. But sometimes he sat in his narrow, old kitchen and gazed out of the dirty window, thinking about his former rival(竞争对手). Perhaps he missed him?

    George was very interested in old dictionaries. He had recently found a collector in Australia who was selling a rare first edition. When the parcel arrived, the book was in perfect condition and George was delighted. But while he was having lunch, George glanced at the photo in the newspaper that the book had been wrapped in. He was surprised—the smiling face was older than he remembered but unmistakable! Trembling, George started reading.

    “Bookends have bought ten bookstores from their rivals Dylan. The company, owned by multi-millionaire Richard Pike, is now the largest bookseller in Australia.”

    Chairman of the State Affairs Commission of the Democratic People's Republic of Korea

Dear Mr. Chairman,

    We greatly appreciate your time, patience, and effort with respect to our recent negotiations and discussions relative to a summit (峰会) long sought by both parties, which was scheduled to take place on June 12 in Singapore.

    We were informed that the meeting was requested by North Korea, but that to us is totally irrelevant (不重要的). I was very much looking forward to being there with you.

    Sadly, based on the unacceptable and unfriendly statement, I feel it is not proper, at this time, to have this long-planned meeting.

    Therefore, please let this letter to serve to represent that the Singapore summit, for the good of both parties, but to the detriment of the world, will not take place.

    You talk about your nuclear capabilities (能力), but ours are so massive and powerful that I pray to God they will never have to be used.

    I felt a wonderful dialogue was building up between you and me, and ultimately, it is only that dialogue that matters. Some day, I look very much forward to meeting you.

    In the meantime, I want to thank you for the release of the hostages (人质) who are now home with their families. That was a beautiful gesture and was very much appreciated.

    If you change your mind having to do with this most important summit, please do not hesitate to call me or write. The world, and North Korea in particular, has lost a great opportunity for lasting peace and great prosperity and wealth. This missed opportunity is a truly sad moment in history.

Sincerely yours,

Donald J. Trump

    President of the United States of America

    Does your local high school have a student newspaper? Only 1 in 8 of New York's public high schools has student newspapers – and many of those are published just a few times a year. A few more are online, which can leave out poorer schools.

    Rebecca Dwarka, an 18-year-old senior who works for her student paper said, “Facebook is the new way of finding out what happened. Nobody wants to actually sit down and read a whole article about it. This makes a 'whole article' sound a little like a long sentence in lonely places.”

    I am not nostalgic about high school student newspapers and never worked for mine. I put out what was then called a personal magazine with a group of friends because we wanted to write about peace, war and rock 'n' roll without school officials warning us not to make jokes about the local officials.

    School newspapers are in decline because students now find out what happened on social networking websites. This is a little discouraging because it proves that for millions of Americans, journalism is becoming a do-it-yourself thing. Every citizen can be a reporter.

    When something happens, we look for social media messages. Facebook posts and Tweets have become the means by which citizens and reporters can prove, deny, pass on stories and express opinions without the press' challenging, researching or slowing the message.

    But truly good journalism is a craft, not just a blog post. It requires seeing something carefully and it uses an eye for details to help prove a larger view. And even journalism that conveys an opinion tries to be fair. If school newspapers begin to disappear, I hope there are other ways for students to learn that.

    I had mixed feelings today, nervous, worried, happy, excited… My heart went down when Miss Chan, our head teacher, said that Matthew and Beth, two students from England, would spend three months with us! I was worried that I had to speak English so much! But at the end of the school day, I was happier than I thought: the morning with them today was more enjoyable than I expected.

    Today is the most unforgettable first day I have had! Matthew is fantastic! His English is clearer and easier to listen to than I thought. The other English student, Beth, is the most helpful girl I've ever met. There were lots of things to do on the first day. Beth offered to help Miss Chan put up all the notices. Of course, some of the credit (功劳) should also go to ME because I translated some of the notices for her. Miss Chan praised us!

    We finished all the preparations 10 minutes earlier than expected, then Beth and I talked for a while, Matthew sang several English songs and did some stand-up comedy (单人喜剧表演) at the party. We all praised him. When the bell rang to end the first school day, none of us wanted to leave.

    When I went back home, I had a little headache. I have probably spoken more English today than the whole of last year.

    It was really a happy day! I hope our friendship can continue, even after they gone back to England!

Biologists from the John Innes Centre in England discovered that plants have a biological process which divides their amount of stored energy by the length of the night. This solves the problem of how to portion out (分配) energy reserves during the night so that the plant can keep growing, yet not risk burning off all its stored energy.

While the sun shines, plants perform photosynthesis (光合作用). In this process, the plants change sunlight, water and carbon dioxide into stored energy in the form of long chains of sugar, called starch (淀粉). At night, the plants burn this stored starch to fuel continued growth.

"The calculations are precise so that plants prevent starvation but also make the most efficient use of their food," said study co-author Alison Smith. "If the starch store is used too fast, plants will starve and stop growing during the night. If the store is used too slowly, some of it will be wasted. "

The scientists studied the plant Arabidopsis, which is regarded as a model plant for experiments. To give the plants some math tests, the biologists let night arrive unexpectedly early or late for them.

During one of the exams, they shut off the lights early on them that had been grown with twelve-hour days and nights. Putting them into darkness after only an eight-hour day means they didn't have time to store as much starch as usual. And this forced the plants to adjust their normal nightly rhythm.

Amazingly, even after this day length trick, the plants did very well in their exams and ended up with just five percent of starch left over at the end of the night. They had neither starved, nor stored starch that could have been used to fuel more growth.

The authors suggested that similar biological calculators may explain how a migratory bird, the little stint, can make a five-thousand-kilometer journey to their summer habitat in the Arctic and arrive with enough fat reserves to survive only approximately half a day more, on average.

The results of the study were published in e Life.
