I am peter Hodes ,a volunteer stem courier. Since March 2012, I've done 89 trips of those , 51 have been abroad, I have 42 hours to carry stem cells（干细胞）in my little box because I've got two ice packs and that's how long they last, in all, from the time the stem cells are harvested from a donor(捐献者) to the time they can be implanted in the patient, we've got 72 hours at most, So I am always conscious of time.

I had one trip last year where I was caught by a hurricane in America. I picked up the stem cells in Providence, Rhode Island, and was meant to fly to Washington then back to London. But when I arrived at the check-in desk at Providence, the lady on the desk said: “Well, I'm really sorry, I've got some bad news for you-there are no fights from Washington.” So I took my box and put it on the desk and I said: “In this box are some stem cells that are urgently needed for a patient-please, please, you've got to get me back to the United Kingdom.” She just dropped everything. She arranged for a flight on a small plane to be held for mere-routed(改道)me through Newark and got me back to the UK even earlier than originally scheduled.

For thiscourier job, you're consciously aware than that box you're got something that is potentially going to save somebody's life.

    It's normal that people sometimes feel nervous. Everybody gets stressed from time to time.{#blank#}1{#/blank#} Some ways of dealing with stress 一like screaming or hitting someone一don't solve (解决)，much. But other ways, like talking to someone you trust, can lead you to solving your problem or at least feeling better.

    Four steps for fighting stress, try taking these four steps, the next time you are stressed:

1) Get support. When you need help, reach out to the people who care about you. Talk to “trusted adult, such as “parent or other relatives. {#blank#}2{#/blank#} They might have had similar problems, such as dealing with a test, or the death of a beloved pet.

2) Don't take it out on yourself. Sometimes when kids are stressed and upset they take it out on themselves. Oh, dear, that's a good idea. Remember that there are always people to help you. Don't take it out on yourself. {#blank#}3{#/blank#}

3) Try to solve the problem. After you're calm and you have support from adults and friends, it's time to get down to business. {#blank#}4{#/blank#} Even if you can't solve it all, you can solve a piece of it.

4) Be positive. Most stress is temporary(暂时的).Remember stress does go away, especially when you figure out the problem and start working on solving it. These steps aren't magic, but they do work. And if you can stay positive as you make your way through a tough time, you'll help yourself feel better even faster.{#blank#}5{#/blank#}

A. Ask for a helping hand to get you through the tough situation.

B. Notice your friends' feelings and find a way to help them.

C. Different people feel stress in different ways

D. Ah, it feels so good when the stress is gone.

E. You need to figure out what the problem is.

F. And don't forget about your friends.

G. Then, find a way to calm down.

    I know that there are times when friends are apart for a while – or even forever – and that your lives take different paths. Yet, I always hope for a happy ending. I know that friends reconnect again when it makes sense.

    My friend Julie and I had a long period in our friendship. We used to see each other daily. I would eat brown rice in her kitchen while we shared our secrets.

    Later, we celebrated each other's weddings. My husband and I welcomed Julie's first son (born on my birthday). By the time he was learning to walk, Julie and her family had moved to another city. We spoke on the phone sometimes and exchanged Christmas cards.

    After they welcomed their third son, they moved to Edmonton, which is a farther city. We haven't seen each other since then. They changed their phone numbers. I received a letter from her, but I couldn't find that envelope later. I e-mailed her a few times, but didn't get a reply.

    It was painful not to be in touch with an old friend. I let it go. I knew that Julie and I would reconnect again, when it made sense.

    Last year, Julie's husband got in touch with me on Facebook. I felt something bad, and soon my feeling proved true: Julie had passed away the month before. She died of cancer.

    I regretted that I had not been part of Julie's support system, or the last years of her joyous, painful time on Earth. I cried. I'm so sorry, Julie, for counting on more chances.

    Last week, I donated my hair in memory of Julie to make wigs (假发) for cancer patients. It was a small way of showing that I loved her and will never forget her. And that I look forward to us reconnecting again – when it makes sense.

    You may not know a lot of people when you start high school. Maybe your friends from middle school are going to a different high school. Even if you know other freshmen(新生), you still feel nervous that you don't know any upper-classmen. How are you going to make friends among this sea of unknown faces?

    Most high schools hold a freshman orientation(训练) before school actually starts. These are helpful not only because you learn your way around the building and get to meet some of your teachers, but you also get to meet fellow freshmen. That way, when you show up on your first day of school, you may already recognize a few familiar faces.

    When you talk to people at orientation, you'll probably find that a lot of them are feeling just like you are. They're all new to the school and don't know what to expect. Talking about a common concern with your classmates can help you develop friendships.

    The work in high school is something freshmen are probably worried about. The work in high school builds on what you learned in middle school, giving you a more advanced knowledge of many subjects. So you may find you have more work to do or that it's a bit more challenging. If you ever find your work too difficult, teachers can give you extra help.

    High school also has more after-school activities than middle school did, such as clubs, music and theater groups and sports teams. This is a good time to explore your interests and try new things.

    Middle school taught you the basics of academics, time management, and social skills while providing you with a little extra support and guidance. High school gives you the chance to learn how to be more independent and responsible.

    Since his students began using Quizlet, English teacher Tristan Thorne has noticed an improvement in their ability to learn and use new words. Quizlet is a learning App, a computer program you use on your mobile phone. It can help users build and test their knowledge of English words. Quizlet has word sets for millions of subjects. And, it is quickly becoming a useful mobile tool for language learners.

    Thorne teachers at Columbia University in New York City. Thanks to learning Apps, Jeff Strack, another English teacher, has also notice improvement in his students' ability to remember information. He teaches at Hostos Community College, also in New York. He and Thorne are part of a growing number of language educators adding mobile Apps to their classes.

    Strack and Thorne seem to agree that the days when teachers would not permit the use of mobile phones are gone. When they use Apps, language learners communicate more differently than in a traditional classroom. Users act on or respond to something, instead of just listening to new information.

    Thorne believes that Apps can help learners become more active in learning. For example, each week, his students are required to add vocabulary words into Quizlet for others to use. He says some Apps also make it easy for students to know their language strengths and weaknesses.

    The biggest improvement Strack has seen in his students is that they are much more active inwhole-class or small-group discussions. “Apps let all students take part in the activity, whether it's a game, quiz or practice activity.” he says.

    Many existing learning Apps are designed for students of all ages and levels. Some are designed for group activities. Some support independent learning. Still some are good for homework. Thorne says he especially likes Quizlet and three other Apps: QR Codes, Socrative and Evernote.

    Nobel prize winners sometimes display as much uniqueness when deciding how to spend their prize money as they did on the work that won them the award in the first place.

    When Sir Paul Nurse won the Nobel Prize for Medicine in 2001, he decided to upgrade his motorbike. A fellow winner in 1993, Richard Roberts, installed a croquet lawn in front of his house. Austrian author Elfriede Jelinek, who won in 2004, said the prize meant "financial independence."

    Lars Heikensten, executive director of the Nobel Foundation, said there were no obvious shopping trends among winners.

    "I think it depends a lot on which country they come from, their personal finances... what kind of incomes they have when they get the prize," he said.

    Real estate, however, is a popular option, at least among those willing to reveal what they spend the money on. Phillip Sharp, the American co-winner of the 1993 medicine prize, decided to splash out on a 100-year-old Federal style house. "I took that money and bought a little bit bigger house... It's a beautiful old place," he told AFP(法新社), adding that "The money is a nice part of the process", but "the important thing about the prize is the recognition."

    For winners of the peace prize the decision is often more clear-cut, as the honor tends to go to politicians, organizations and activists who are under more public supervision. Many, like US President Barack Obama in 2009 and the European Union in 2012, donate to charities.

    Literature winners tend to be more private about how they use the money, but the choice is often equally straightforward. "Even if Nobel-winning authors are quite well known, many of them will not have made much money from writing," said Anna Gunder, a Nobel literature expert at Uppsala University. While the prize might keep the wolf from the door for some years, giving them freedom to write, it can also briefly have the opposite effect. "It really changes their careers… During the first year after they've won they often write less, but they generally continue after a year or two," said Gunder.
