The days when a cellphone was used for nothing beyond calling and texting are gone. Today, we turn smart phones into magical machines with apps that transform them into musical instruments or business machines or video players. But it turns out that we are only searching the surface. Who knew that smart phones would make pretty good satellites?{#blank#}1{#/blank#}

Smart phones forecast the weather

      Networking expert Open Signal has discovered something interesting: the sensors in Android phones designed to measure battery  temperature, light, pressure and 80 on can be used to generate surprisingly accurate weather reports. {#blank#}2{#/blank#}

Smart phones save the rainforests

       Detecting illegal logging(盗伐) may sound like a novel app, {#blank#}3{#/blank#}: in Indonesia, the non-profit organization Rainforest Connection' wants to use donated Android phones to detect illegal logging. As Newscientist reports, “The phonesare equipped with solar panels specifically designed to take advantage of the brief periods when light reaches the forest floor. Their microphones stay on at all time, and the software listens for the sound of a chainsaw(链锯).”

        Researchers at the university of Illinois have developed an iPhones app that turns the phone into a fully featured mobile medical lab that uses the phone's camera to detect proteins, bacteria, viruses and other organisms.

    Doctors say anger can be an extremely damaging emotion, unless you learn how to deal with it. They warn that anger can lead to heart disease, stomach problems, headaches, emotional problems and possibly cancer.

     {#blank#}1{#/blank#} Some people express anger openly in a calm reasonable way. Others burst with anger, and scream and yell. But other people keep their anger inside. They can not or will not express it. This is called repressing anger.

    For years many doctors thought that repressing anger was more dangerous to a person's health than expressing it. They said that when a person is angry, the brain releases the same hormones (荷尔蒙). They speed the heart rate, raise blood pressure, or sugar into the blood, etc. {#blank#}2{#/blank#} 

    Some doctors say that both repressing and expressing anger can be dangerous. They believe that those who express anger violently may be more likely to develop heart disease, and they believe that those who keep anger inside may face a greater danger of high blood pressure.

     {#blank#}3{#/blank#} They say the first step is to admit that you are angry and to recognize the real cause of the anger, then decide if the cause is serious enough to get angry about. If it is, they say, “ {#blank#}4{#/blank#} Wait until your anger has cooled down and you are able to express yourself calmly and reasonably.”

    Doctors say that a good way to deal with anger is to find humor in the situation that has made you angry. {#blank#}5{#/blank#}

A. Anger may cause you a cancer.

B. Do not express your anger while angry.

C. In general the person feels excited and ready to act.

D. They said that laughter is much healthier than anger.

E. Doctors say the solution is learning how to deal with anger.

F. Anger is a normal emotion that we all feel from time to time.

G. Expressing anger violently is more harmful than repressing it.

    I like travelling very much.{#blank#}1{#/blank#}They are wonderful adventures filled with new sights and experiences. And my wife and I have another trip in the planning stages．

    We're home now and have settled back into our daily routine of life.{#blank#}2{#/blank#} I find that when I am at home, particularly for a while when we have just returned from a trip, I feel very comfortable. Perhaps it is because everything around me is familiar and the daily routine is so much the same and I can move through it almost without thinking.{#blank#}3{#/blank#}Perhaps it is because we can have meals at home instead of always being in restaurants, although it's nice to let someone else do the cooking, and because I can sleep in my own bed. There are times I think it would be nice to simply stop travelling and stay home．{#blank#}4{#/blank#}

    Yet I guess I am probably a restless soul because I know that after I have been home for a while I will start to think about other places we might go and other things we want to see.{#blank#}5{#/blank#} We will travel again and we feel fortunate to be able to do so. Still, one of the best things about travelling for me is coming home. I'm very comfortable here at home even if it is difficult to say exactly why．

A. I enjoy local food while travelling．

B. I like being home，for whatever reason．

C. Perhaps it is because our friends are here．

D. And I enjoy my daily life at home so much．

E. It's lucky that my wife and I both love travelling.

F. The world is filled with people who are travelholic．

G. I have been fortunate enough to make trips to many countries.

    Whoever wrote the song “it's the Most Wonderful Time of the Year” must have never experienced Holiday blues. Fortunately, psychological research suggests some effective ways you can beat the holiday blues. The key point is that sadness and other tough emotions are not what we should try to avoid. {#blank#}1{#/blank#}. Here are four strategies to help you make your own happiness recipe this holiday season.

    Don't force cheer

    At family gatherings with cousins you secretly can't stand, you tend to put on a happy face. Indeed, that might even seem like the most mature response—no drama, no conflict. But a 2011 study followed dozens of bus drivers, looking to see when they gave forced or honest smiles at their passengers. The results showed when the drivers pretended to have a good mood, their actual moods got worse. {#blank#}2{#/blank#}.

    Let off sadness

    The results of the bus-driver study can be explained by researchers, who find that negative feelings like sadness or anger only increase when we try to control them. {#blank#}3{#/blank#}. We don't like contradictory behavior.

    Respond cautiously

    Recently, scientists have been paying special attention to the benefits of caution. When you respond cautiously to an emotional trigger (e.g. overcooking the holiday turkey), you pause rather than reacting at once. {#blank#}4{#/blank#}. Besides, it is associated with less anxiety, and may even carry physiological benefits.

    {#blank#}5{#/blank#}.

    Of course, the holidays will bring a mix of highs and lows, but the most important lesson to keep in mind is that this variety of emotions might be the best thing possible for your overall well-being. In other words, sadness, anger, and other difficult emotions are nothing to fear. Just make sure you're balancing them with lighter experiences. And don't forget to give yourself a break.

A. Relax your mind

B. Enjoy a mix of emotions

C. We tend to deny the important function emotions serve

D. Instead, they can help contribute to a healthy and happy life

E. So trying to force happiness seems to have the opposite effects

F. A cautious response to a negative event reduces sadness we experience

G. We feel bad when our appearance contradicts how we truly feel inside

    We know that choosing a college major can be very hard. But have no fear! Your choice of major will not lock you into a specific career for the rest of your life. Here's what you need to know about college majors before you commit.

    What is a major?

    {#blank#}1{#/blank#}Beyond general college requirements, you'll also take a group of courses in a subject of your choosing such as Chemistry, Literature, or Political Science.

    How important is my major?

    The major you choose will neither predict nor guarantee your future. Many graduates find jobs that have nothing to do with what they studied in college. If you intend to earn a professional degree after college, you will probably need certain courses. {#blank#}2{#/blank#}

    When do I declare a major?

    This varies widely across schools and programs. {#blank#}3{#/blank#}Others require that you declare upon a major by the time that you set foot inside your first class.

    {#blank#}4{#/blank#}

    Definitely. One of the most exciting aspects of college life is that it introduces you to new subjects and arouses new passions. However, keep this in mind. Every major has necessary coursework. If you change your major late in the game, it may take more than the traditional four years to earn a degree.

    What are minors and double majors?

    If one field of study doesn't satisfy your intellectual appetite, consider a minor. A minor is similar to a major in that it's an area of academic concentration. {#blank#}5{#/blank#}A double major provides you with an understanding of two academic fields. It allows you to become familiar with two sets of values and views while it also requires you to fulfill two sets of requirements.

A. Can I change my mind?

B. Is my major time-consuming?

C. It's your specialized area of study in college.

D. Most students find one major is more than enough.

E. Some schools may give you one year or more to decide.

F. But many future doctors major in non-science related fields.

G. The only difference is that it doesn't require as many classes.

Courage is a quality that everyone has, but it sometimes disappears because of bad experiences or memories.{#blank#}1{#/blank#}So, how can people build courage? By identifying the source of any lack of courage and actively changing your behaviour, you can build courage. 

Determine your specific fears. People are often unwilling to admit that they are afraid of something. In order to begin building courage, you need to determine your specific fears.{#blank#}2{#/blank#}This may help you to work out a plan to overcome them and build your courage. 

Recognize your courage. Just as it's important to identify your fears, you should also recognize that you also have courage in many situations. {#blank#}3{#/blank#}It can help you to figure out how to apply this quality to situations that cause fear. It can also help develop your behaviour and build courage.

Develop a practical plan to build your courage. Once you've identified your specific fears and recognized situations where you exhibit courage, make your plan to build your courage and update it when necessary. {#blank#}4{#/blank#}The reason for that is it helps you be on track if you have difficulties and see your progress over time.

Avoid comparing yourself with others. Every person is different and comparing yourself with other people can minimize your self-confidence. Focusing on yourself is essential to building your confidence and courage.

 {#blank#}5{#/blank#}Two characteristics of courageous people are that they not only have confidence, but also they believe in their ability to succeed and overcome fears. By developing and projecting confidence in yourself, you set yourself on the path to building and maintaining courage. 

A. Part of building your courage is taking risks.

B. Embrace the positive and avoid the negative.

C. Make a list of your fears as you figure them out.

D. Having a clear strategy you can follow is important.

E. Take the time to acknowledge that you are courageous.

F. Have confidence and believe in your ability to be courageous.

G. Showing courage is necessary to succeed in many situations in life.
