While dog keepers realize their dogs can read their moods accurately,scientists have always been a little doubtful.Now thanks to some researchers at the University of Veterinary Medicine in Vienna,Austria,we finally have some convincing evidence.

    For their study,biologist Corson Miller and his team exposed eleven selected dogs to digital images of women that were either angry or happy.Half the dogs were rewarded for touching the screen when shown a happy face,while the other half got their treat for selecting those that appeared angry.

    Interestingly,the dogs were not provided with the entire face.Some dogs were shown only upper halves while the others observed lower halves.That's because the scientists believe humans show their emotions on their entire face.

    After some training like how to recognize small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions,the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face.The researchers concluded the dogs were smart enough to read human emotions.

    They also found those being trained to read angry expressions took a longer time to learn.They guess it may be because dogs find angry faces disgusting,causing them to withdraw quickly.However,once the smart dogs realized they were getting rewarded,the trepidation seemed to disappear.In fact,the dogs had such a good time playing the computer "game" that scientists had a hard time keeping them away from the touch screens after the study was completed.

    The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctl. Since the touchscreen models were all females, this confirmed what has been observed in previous studies-dogs are more efficient at reading facial expressions of people that are the same gender as their owner.

    Most people who move to a foreign country may experience a period of time when they have a lot of stress in the new culture. This feeling is often called “culture shock” and it is important to learn how to deal with culture shock. First of all, you should know that everyone in a new situation will go through some form of culture shock. There are four general stages of cultural adjustment(适应).

    The first stage is usually referred to as the honeymoon stage. Upon arriving in a new environment, you'll be interested in the new culture. Everything will seem exciting, and everyone will seem friendly and helpful.

    The second stage is called the withdrawal stage. The excitement that you felt before changes to frustration(沮丧) as you find it difficult to deal with new problems. The language is hard to learn; friends are hard to make; simple things like shopping and going to the bank are challenges. It is at this stage that you are likely to feel anxious and homesick.

If you are one of those who manage to stick it out (坚持下来), you will enter the third stage—- the recovery stage. At this point, you'll feel more confident in the new culture. You'll start to understand and accept the way things are done and the way people behave in your new environment.

The last stage is the stability stage—- this is the point when people start to feel at home in the new culture. At this stage, you will behave well in the new culture, and prefer some aspects(方面) of the new culture to your own culture.

    There is, in a sense, a fifth stage to this process. If you decide to return home after a long period in a new culture, you may experience what is called “reverse culture shock”. This means that you may find aspects of your own culture “foreign”, because you're so used to the new culture. Reverse culture shock is usually pretty mild(温和的) and doesn't last for very long.

    Eat your vegetables.Wash your hands.Always say“please”and“thank you”.We are full of advice for our children, but when it comes to money,we often have little to say.As a result,our children may grow up with clean hands and good manners,but without any idea how to manage their money.

    Here are some basics that will help guide them their entire lives:

    Show them the future.If your 13-year-old girl were to save $1.000,invest（投资）it at 8% and add $100 every month,by the time she's 65,she would have $980,983!

    Be careful of credit（信用）.Credit cards can help you buy necessary things and build a credit history,but they must be used responsibly,which means paying off your debt in time.Explain to your children that when you buy something using a credit card,you can easily end up paying two or three times what you would have paid if you used cash.

    Teach patience.Suppose your child wants a new bicycle that costs $150.Rather than paying the cash,give him some regular pocket money and explain that by putting aside,say,$15 each week,he will be able to buy it for himself in only ten weeks.

    Provide incentive（激励机制）.Tell your children the importance of saving."For every dollar he or she agrees to save and invest rather than spend,you agree to add another dollar to the pot,"says Cathy Pareto,expert in money planning.

    Explain your values.Values and money are deeply intertwined（纠缠在一起）,says Eilleen Gallo,co-author of The Financially Intelligent Parent.When your child demands that you buy something,explain why you really don't want to buy it.“You might say,‘I'd rather save that money for your education,'”advises Gallo.Every time you spend or don't spend money,you have a chance to share your values.

    You may not know a lot of people when you start high school. Even if you know some new students, you still feel nervous that you don't know any upperclassmen (高年级学生) and teachers. How are you going to make friends among this sea of unknown faces?

    Most high schools welcome new students before school actually starts. These are helpful not only because you learn your way around the buildings and get to meet some of your teachers, but also because you get to meet new students. 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, you'll probably find that a lot of them are feeling just like you. 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 (有挑战性的). If you ever find your work too difficult, teachers can give you extra help.

    High school also has more activities after class than middle school, 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 (独立的) and responsible (有责任的).

    Microsoft has developed a new smartphone app that interprets eye signals and translates them into letters, allowing people with motor neurone disease to communicate with others from a phone.

    The GazeSpeak app combines a smartphone's camera with artificial intelligence to recognize eye movements in real time and convert them into letters, words and sentences. For people suffering from ALS（渐冻症）, also known as motor neurone disease, eye movement can be the only way they are able to communicate.

    "Current eye-tracking input systems for people with ALS or other motor impairments are expensive, not robust under sunlight, and require frequent re-calibration and substantial, relatively immobile setups," said Xiaoyi Zhang, a researcher at Microsoft who developed the technology.

    "To mitigate the drawbacks…we created GazeSpeak, an eye-gesture communication system that runs on a smartphone, and is designed to be low-cost, robust, portable and easy to learn."

    The app is used by the listener by pointing their smartphone at the speaker. A chart that can be stuck to the back of the smartphone is then used by the speaker to determine which eye movements to make in order to communicate.

    The sticker shows four grids of letters, which each correspond to a different eye movement. By looking up, down, left or right, the speaker selects which grids the letters they want belong to. The artificial intelligence algorithm is then able to predict the word or sentence they are trying to say.

    Zhang's research, Smartphone-Based Gaze Gesture Communication for People with Motor Disabilities, is set to be presented at the Conference on Human Factors in Computing Systems in May.

    For high school leavers starting out in the working world, it is very important to learn particular skills and practise how to behave in an interview or how to find all internship(实习). In some countries, schools have programs to help students onto the path to work. In the United States, however, such programs are still few and far between.

    Research shows that if high schools provide career-related courses, students are likely to get higher earnings in later years. The students are more likely to stay in school, graduate and go on to higher education.

    In Germany, students as young as 13 and 14 are expected to do internships. German companies work with schools to make sure that young people get the education they need for future employment.

    But in America, education reform programs focus on how well students do in exams instead of bringing them into contact with the working world. Harvard Education school professor Robert Schwartz has criticized education reformers for trying to place all graduates directly on the four-year college track. Schwartz argued that this approach leaves the country's most vulnerable(易受影响的) kids with no jobs and no skills.

    Schwartz believed that the best career programs encourage kids to go for higher education while also teaching them valuable practical skills at high school. James Madison High School in New York, for example, encourages students to choose classes on career-based courses. The school then helps them gain on-the-job experience in those fields while they're still at high school.

    However, even for teens whose schools encourage them to connect with work, the job market is daunting. In the US， unemployment rates for 16-to-l9-year-olds are above 20 percent for the third summer in a row.

    “The risk is that if teenagers miss out on the summer job experience, they become part of this generation of teens who had trouble in landing a job,” said Michael, a researcher in the US.
