With brown curly hair and a pair of glasses, 19-year-oldNicholas Allegra from New York state, US, looks like a real-life Harry Potter.However, rather than waving a wand, Nicholas is a "wizard " at"jailbreaking ". This is probably why he ended up with an intern­shipat Apple, a job many of his fellow Brown University students dream of.

Jailbreaking is the process of removing the limitations set byApple on devices with the iOS oper­ating system. These devices include theiPhone, iPod Touch, and iPad. It allows users to gain full access to theoperating system and download additional materials that are unavailable through the official Apple App Store.However, it is estimated that Apple loses $100 million (640million yuan) fromjailbreaking each year.

Nicholas, with a famous nickname "Comex", is theteenage hacker behind the jail-breaking site JailbreakMe. com. The site tellsusers how to unlock their iPhones using software that is not approved by Apple.The jailbreaking software he made has been downloaded millions of times byusers around the world.

Then Forbes magazine suggested in an article that Apple's securityteam might need him as a new intern. It seems that they do. Little more than aday after Steve jobs stepped down as CEO, Apple welcomed Nicholas Allegra.Nicholas wrote on his Twitter on August 26 that " It's been really, reallyfun, but it's also been a while and I've been getting bored. So, the week afternext I will be starting an internship with Apple.

Apple is not the only company embracing the skills ofhackers. Facebook recently hired iPhone jailbreaker George "Geohot"Hotz as a full-time employee.

However, there are still hot debates about whether employinghackers is a wise solution. The word "hacker" has always had a doublemeaning. In the press, "hacker" means someone who breaks intocomputers. They steal from people's bank ac­counts, download sensitiveinformation and attack legal websites. Among computer lovers, it means a coolpro­grammer who can make a computer do whatever he wants.

Hiring a hacker does have its advantages. A talented hacker isprobably quite capable of finding problems and suggesting corrections. On theother hand, because of a hacker's former behavior, many people doubt theirmorals .Can the company trust them with its valuable assets ? And can someonewho is so used to working alone in the dark fit into a new role within acompany?

One thing is for sure- Comex isn't the first member of thehacker community to land the job of his dreams. It's likely that he won't bethe last.

    Machu Picchu is an unusual site in Peru and one of the most mysterious wonders of the world. Built at almost 10,000 feet on the top of an Andean mountain, the Incas built hundreds of structures made of stone. A large number of Machu Picchu's surrounding structures date back to the early 13th century, but it was considered a chief sacred site far before then. The Inca people changed the large site into a very small but wonderful city, completely self-sufficient and hidden from below. Agricultural terraces (梯田) surrounded the entire city, fed by natural spring water, supporting the entire population.

Inca Trail

    The trail is one of the most famous in the world and regarded as one of the best. It covers only 26 miles, combining cloud forest, green mountain scenery, forest, and plenty of tunnels, paving stones, and ruins. The four-day hike begins slowly but quickly changes into a difficult journey suitable for those in excellent shape. The trail winds through the Andes, leading alongside and through ruins. Though independent hiking was once permitted, now it must be done with a guide.

Funerary Rock

    It is believed that the Funerary Rock at Machu Picchu was used as a place to prepare Inca nobles for preservation, or mummifying (做成木乃伊), a common habit among the tribe. Nobles would be laid out to be mummified by the hot sun and freezing cold nights after their organs were removed. The rock is also famous as a spot from which a view of the city is afforded.

Temple of the Sun

    Within the city's castle, deep within Machu Picchu, is the Temple of the Sun, accessed only by the Emperor and

    Inca priests. It means the Inca's advanced knowledge of religion, weather, and nature, showing the great extent

    Incas went to adapt to and learn about nature. Still unbroken, the temple was built to honor the god Inti, who is exactly the sun. The temple was effectively protected. It was also a very important scientific center, built in half-moon shape with openings facing north and east. The windows' shadows in the center of the temple helped see the start of winter solstice (至日), showing farming season.

    With the Chinese language growing in popularity,the UK government plans to invest（投资）10 million pounds to help more kids learn Mandarin（普通话）.Do you think it is necessary for the UK pupils to learn Mandarin?Some people share their opinions online.

    Ted(UK): The learning of any language can be valuable and rewarding,but it is not suitable for everyone. Chinese is a difficult language to learn and the UK has a poor reputation for teaching foreign languages.Why should they learn Chinese when most people in the world speak English?

    Mark(US): I studied French for 2 years in high school and German for 4 years in college.I studied Mandarin informally for about 4 months before moving to China.Now I speak Mandarin every day as my wife doesn't speak English.But it is far from being fluent.Learning additional languages is a great thing,which offers a different perspective on the world around us.Nowadays,it's almost necessary to be able to speak more than just your native tongue.

    George(UK): No,unless they're taught from a very early stage of childhood.Mandarin is so difficult.If China really is going to dominate the world,it'll have to do so by speaking the world's dominant language—English.

    Sam(UK): I don't think Chinese will become as widely spoken throughout the world as English.It is too difficult to learn as a second language.To learn Chinese you completely have to devote yourself to learning how to write and read it.If you have to learn it besides other subjects you can't be good at it.But Chinese will become more popular, and that is a good thing.

    Happy, angry, amazed—these are some of the emotions we like to express these days when we're sending a message on our smartphones! That's why many of us now add little pictures to our texts to brighten up someone's mobile screen but we're also using them as a quick way of telling someone how we're feeling. Yes, emojis (表情符号) have become a popular tool for communication.

    The emoji was first invented in Japan in the late 1990s and the word “emoji” comes from the Japanese words for “picture” and “character”. The number of different images has greatly increased since then and now we have a picture for nearly every mood or situation.

    Why are emojis widely used today? Professor Vyv Evans says, “Increasingly, what we're finding is that digital communication is replacing face-to-face talk in some ways. One of the reasons why emojis are so interesting is that they really do enable us to express our emotional selves much more effectively.”

    Another advantage of emojis is that they are an international language—they don't use words but tell a message with pictures so they can be easily understood whatever your native language is.

    But as linguist (语言学家) Neil Cohn says, “To many, emojis are an exciting evolution (进化) of the way we communicate; but to others, they are linguistic Armageddon.” It does show by using emojis, there is a lot more to our communication than words alone, but does this also mean that the traditional writing will die out one day?

A Letter that Changed My Life

    I was about 30 years old and was working as a firefighter in the South Bronx's Engine Co. 82. It was a restful Sunday and between alarms I rushed to the office to read a copy of the New York Times. I read an article on the Book Review section which openly stated what I took to be a calumny – that William Butler Yeats had gone beyond his Irishness and was forever to be known as a universal poet. As I read it, my blood began to boil.

    There were few things I was more proud of than my Irish heritage, and ever since I first picked up a book of his poems from a shelf when I was in the military, Yeats had been my favorite Irish writer, followed by Sean O'Casey and James Joyce.

    I grabbed a piece of paper and wrote out a letter of anger to the editor. Throughout Yeats' poetry, his view of the world and the people in it was basically Irish. He had lived his life and written his poetry through the very essence of his Irish sensibility. It was offensive to think Irishness was something to be transcended(超越).

    I don't know why I felt it my duty to safeguard the reputation of the world's greatest poet. I just knew that I had to write that letter.

    After my letter got published, I received a letter from The New Yorker, asking for an interview. When my article Fireman Smith appeared in that magazine, the editor of a large publishing firm called me, asking if I was interested in writing a book about my life. I had little confidence to write a whole book, though the subject was worthy. I wrote Report From Engine Co. 82 in six months, and it sold really well. In the years that followed, I wrote three more best-sellers.

    Being a writer had been far from my expectations. How had it happened? I often found myself thinking about it, and my thoughts always came back to that letter to the New York Times. For me, the writing was a natural consequence of the passion I felt and the subjects represented the great values burning within me as I wrote.

    Over the years, my five children have come to me with one dilemma or another. My answer is always the same. Think about what you're feeling and measure the heat of the fire in your heart, for that is your passion. Your education and your experience will guide you toward making a right decision, but your passion will enable you to make a difference in whatever you do. That's what I learned the day I stood up for Ireland's greatest poet.

    About 30 years ago, I left Cuba for the United States with my son. After getting settled finally in Brunswick, New Jersey, I enrolled (注册) my son in kindergarten. Several weeks later, my son's teacher asked me to meet him at his office.

    In the teacher's office, and exchange of greetings was followed by his questions: "Is your son mentally retarded (弱智的)? Does he suffer from any kind of mental disability?"

    Was he talking about my wonderful Scola? No, no, it can't be. What a helpless, lonely moment! I told him that Scola was a quiet, sweet little boy, instead. I asked him why he was asking me all these questions.

    My son could not follow the teacher's directions, he told me, and thus, Scola was disrupting the class. Didn't he know my son did not speak English yet? He was angry: "Why hasn't your son been taught to speak English? Don't you speak English at home?"

    No, I didn't speak English at home, I replied. I was sure my son would learn English in a couple of months, and I didn't want him to forget his native language. Well, wrong answer!

    What kind of person would not speak in English to her son at home and at all times? "Are you one of those people who come to this country to save dollars and sent them back to their country, never wanting to be a part of this society?"

    Needless to say, I tried to tell him I was not one of "those people." Then he told me the meeting was over, and I left.

    As I had expected, my son learned to speak English fluently before the school year was over. He went on to graduate from college and got a job, earning close to six figures. He travels widely and leads a well-adjusted, contented life. And he has benefited from being bilingual (双语的).

    Speaking more than one language allows people to communicate with others; it teaches people about other cultures and other places- something very basic and obviously lacking in the "educator" I met in New Jersey.
