The following is a selection of the 2017 summer programs offered at colleges and universities around the world．

    These days, more and more Chinese people enjoy sending and receiving messages on the phone. It can help them to get the latest news and communicate with friends. But I think I should read more books besides the textbooks, the more, the better. It can open my eyes and improve my language skills. Of course, it also can help me to get good grades. Do you know how to read more and learn more? Here are some tips for you.

    Clear your purpose for reading

    Before you start reading, ask yourself why you are reading this book. Most people read for two main reasons, pleasure or knowledge. Clearing about your reading purpose can not only help you choose the books you really need to read, but also remind you why reading the book is important to you, so you will keep reading and complete the book faster.

    Read only what you are interested in

    No matter what you are reading, it is important to enjoy what you read. Your friends may tell you the books they love, but those books might not necessarily be the ones you enjoy.

    Give up books that you don't enjoy

    You may have chosen books that you are interested in, and they are right to your purpose. But while you are reading them, there may still be some books that you don't enjoy reading. Whenever you realize that you aren't enjoying the book you are reading, give it up. Remember reading shouldn't be a chore (苦差事).

    Set a reading goal

    It is interesting that I read the books borrowed from libraries faster than those I bought. The reason is the books I bought don't have a due date! I don't need to return those books. Having a reading goal helps you work out how much reading you need to do in a week or even a day. Before you read each book, ask yourself what time you need to complete this book by.

    When people find themselves in difficult conflicts, they often turn to mediation(调解). Mediator are advised to listen attentively, avoid favoring the ideas of one party, and make both sides feel at ease. Surprisingly, new research that my colleagues and I conducted shows that, to effectively help people settle their conflicts, mediators should adopt a hostile(敌对的) attitude rather- than a calming one. A hostile mediator, we find, brings better results than a nice one

    Why would adding more negativity to an already hostile situation prove beneficial? Consider how parents typically react when they can't get their children to stop quarreling: "I don't care who started it, both of you, go to your rooms!" At first sight, a calm mediator seems likely to be more effective. But as anyone with brothers or sisters knows, parents' seemingly unsympathetic treatment of the situation can have an unusual effect,

    In our research, we created situations in which pairs of negotiators were part of a heated conflict. In some cases, the mediator had a "nice" approach-calm and polite. In others, he was hostile-aggressive and somewhat rude. Across different types of conflicts, we found that negotiators were more willing and able to reach an agreement in the presence of a hostile mediator than in the presence of a nice one.

The main result of the test is not that hostility pays off. In fact, recent research has documented the social costs of negative behavior. For example, being the target of rude behavior reduces people's performance on a variety of tasks. Other research shows the social benefits of positive behavior. People are more likely to close deals and become future business partners.

    Even with the widespread social benefits of positive behavior and costs of negative behavior, hostility can pay off in certain situations.

    Here's an idea whose time has come: A flu shot that doesn't require an actual shot.

    For the first time, researchers have tested a flu vaccine patch (疫苗贴) in a human clinical experiment and found that it delivered as much protection as a traditional injection with a needle. Doctors and public health experts have high hopes that it will increase the number of people who get immunized (免疫的) against the flu.

    Seasonal flu is responsible for up to half a million deaths around the world each year according to the World Health Organization. A team led by Georgia Tech engineer Mark Prausnitz has come up with an alternative method that uses “microneedles”. These tiny needles are so small that 100 of them, arranged in order on a patch, can fit under your thumb (拇指). Yet they're big enough to hold vaccine for three types of flu.

    None of the study volunteers had serious side effects. The groups that got patches had mild skin reactions that were not seen in the regular needle group, while the volunteers in the regular needle group were more likely to experience pain. Overall, 70 percent of the volunteers who got vaccine patches said they'd rather use them again than get a traditional flu shot. The study authors declared it a success on all fronts.

    The biggest beneficiaries could be people in low- and middle-income countries, where flu vaccines are hard to come by. Reducing pain is nice, but other benefits—the patch costs less, is easier to transport, doesn't require refrigeration, can be self-administered and doesn't cause waste of needles—are even better.

    "Microneedle Patches have the potential to become ideal candidates for vaccination programs," wrote Katja Hoschler and Maria Zambon of Public Health England.

    The movie The Wizard of Oz has thousands of fans around the world. But back in 1939 when the film opened, audiences were not particularly fond of it. It was only a modest box office success. It was nominated for Best Picture at that year's Academy Awards, but so were nine other great films. It lost out to Gone with the Wind.

    The Wizard of Oz really gained an audience when it was broadcast regularly on TV. That began in the 1950s. The film's plot follows young Dorothy who is knocked unconscious during a tornado. She dreams about following a Yellow Brick Road through the Land of Oz to the Emerald City. She wants to meet the Wizard of Oz who lives there. He's the only one who can help her to return home to Kansas. Along the way she makes friends with the Scarecrow, the Tin Man and the Cowardly Lion. They help her and her dog Toto overcome the Wicked Witch of the West!

    According to the Library of Congress, The Wizard of Oz is the most watched movie of all time. What is it about the film that appeals to people? It includes themes that people can relate to. Through most of the movie Dorothy is trying to get home to Kansas. When she finally gets to go, she speaks the words, "there's no place like home." People identify with that thought. Home is the welcoming place where they feel secure.

    At the beginning of the film, Dorothy sings of a place "over the rainbow." There, the dreams that you dare to dream really do come true. So while home is a great place, dreaming about something different is all right too.

    The Wizard of Oz also deals with courage. Dorothy learns that true courage isn't being unafraid. It's facing danger when you are afraid. Her friends face plenty of danger to rescue her.

    As one of the true classics of American literature, The Wizard of Oz has stirred the imagination of young and old alike for over four generations. Celebrate the 80th year of this fabulous film by watching it again.

If you were told to stop from breathing through your nose, could you do it? Journalist Nestor made it for about 10 days,{#blank#}1{#/blank#} (plug) up his nose and breathing only through his mouth as part of an experiment at Stanford University. The effects were systemic—sleeping troubles, high blood pressure and, of course, discomfort.

Breathing is so automatic an activity that most of {#blank#}2{#/blank#}(we) never think about doing it. But as Nestor shows through his own experiences and conversations with dozens of {#blank#}3{#/blank#} (expert), the way we breathe makes {#blank#}4{#/blank#} difference to the body's overall health.{#blank#}5{#/blank#} (base) on the results of the experiment, he published a book Breath: The New Science of a Lost Art, where he explores everything from the role our noses play in hormone regulation（激素调节） and digestion, to {#blank#}6{#/blank#} some athletes build up the lung capacity（肺活量） to run marathons in extreme conditions or div e into icy water for more than an hour at a time. The topic is {#blank#}7{#/blank#} (seeming) simple—an entire book about breathing. But actually every chapter {#blank#}8{#/blank#} (reveal) new details about how body and breath work together at the same time.
