Have you ever felt a sudden feeling of joy because you heard a favorite song playing? Then you know that music can have a strong effect on your emotions. {#blank#}1{#/blank#} It can help get you out of a bad mood (心情) or stay in a good one, says Alicia Ann Clair, professor at the University of Kansas. {#blank#}2{#/blank#}

    To cheer up, listen to Latin music or anything with a strong beat or a fast speed{#blank#}3{#/blank#}. When you want to relax after a busy day, music with a slower speed can calm you down.     

    Listen to calming music before you start any stressful activities, advises Dr. Clair. "Once you' re in a good state of mind, it' s easier to keep it." You can lower stress at work with music, too, by playing relaxing tunes (曲调). {#blank#}4{#/blank#} "If you listen to them all day long, you'll stop noticing them," Dr. Clair explains. Then the music won't have any effect.

    {#blank#}5{#/blank#}."To feel energetic, start with something relaxing, and then gradually increase the speed and beat," says Dr. Clair. For example, first play some nice slow love songs, and then listen to something more energetic. When you want to calm down after a busy week at work, just do the opposite.

    A hobby is an inverstment of time. It also can be an investment of money and commitment. Many people choose to developing more than one type of hobby. {#blank#}1{#/blank#} When it comes to choosing the hobby, consider the following factors.

    Hobbies are usually an activity of some sort that brings out a certain skill that you have. When you have a talent like painting or woodworking, it can be easy to determine which hobby suits your skill. {#blank#}2{#/blank#} Skill can be developed and challenged as you go along. It is not a necessary requirement. A hobby is fitting because you love it, not because you're a professional at it.

    Some people particularly enjoy taking part in hobbies that they can do in a group with others. It can be a lot more fun to become a member of a hobby group than to sit alone in your basement. {#blank#}3{#/blank#} It's important to share interests and network with other hobby enthusiasts that do what you do.

    {#blank#}5{#/blank#} But most of the skilled hobbies like art, building or writing have a series of lessons or tutorials that you can take to further your skills. In some cases it's a really good idea to take lessons, especially if you are clueless as to where or how to begin. Step by step books for most hobbies can often be found in bookstores as well.

    View emails with a careful eye

    It's best to view all emails with care. Hackers can make emails look like real company emails.{#blank#}2{#/blank#} It's best to search for the original source of the information, and try to find the direct link from the site instead of using the link provided in the email.

    Use two-factor authentication（双重认证）

    Two-factor authentication adds a second level of security to an account.{#blank#}3{#/blank#}It's a security option that requires a password as well as an additional piece of information only the user would know.

    Update apps and operating systems

    {#blank#}4{#/blank#}   While these updates may appear to only change the way your phone's software looks, they often come with security improvements. There may be a bug（软件漏洞）. Those bugs are discovered by cell providers or smartphone makers, so it's a good idea to upgrade them.

    {#blank#}5{#/blank#}    It's no surprise that changing your password has always been a basic form of protection. But what we pick as passwords and how we manage them are important. First, passwords should never include your personal information. So stay away from names and birthdates. Ideally, passwords are a combination of lowercase（小写）and uppercase（大写）letters and random characters. It could be a strong, long password that doesn't have any personal information, making it harder to remember.

A. Manage passwords security

B. Here are some steps to make it.

C. Often users are unwilling to update their mobile devices.

D. Combine your personal information with random figures

How northern Europeans beat the winter blues

    Ask a child from northern Europe to draw two pictures—one on a rainy day and a second in the sunshine—and this is what you will get: in the first, as raindrops fall from the top of the page, the man behind the window has an unhappy expression. When a yellow sun sends out some light from the corner, the man is smiling.

    Northern Europeans associate rain with sadness and sunshine with happiness. They think this is true because they are so aware of how their environment affects them{#blank#}1{#/blank#}In October 2008, a group of researchers examined the influence of different daily weather factors, including temperature,wind and sunlight, on 1,200 participants. The conclusion was that good or bad weather had little effect on people's feelings{#blank#}2{#/blank#} A person who is upset on dark or cold days suffers from a negative mood, and he will be likely to experience a sad winter. This is the basis of an illness called Seasonal Affective Disorder (SAD){#blank#}3{#/blank#} 

    AniKalayjian, professor of psychology at Fordham University, advises that we should take steps to strengthen the brain's system against weather-driven mood changes. Research on SAD has been focused on the brain's response to darkness and light. When our eyes detect darkness, the brain gives off melatonin, which starts sleep cycles{#blank#}4{#/blank#} It takes over to help us wake up and feel better when we detect light.“We can encourage people to take charge of their feelings,” says Kalayjian.“We tell them to leave the computers and the indoor games and get out there in the sun{#blank#}5{#/blank#}”

    A day of rain can potentially destroy your plan and affect your mood. But as the Scottish comedian Billy Connolly once said:“There is no such thing as bad weather, only the wrong clothing.”

A. Another chemical called serotonin, however, can make people happy.

B. It affects about10% of the population of northern Europe each year.

C. That's when people can recharge their serotonin and get a better mood.

D. Yet that link has no scientific basis.

E. Most studies prove that a negative feeling is associated with bad weather.

F. They determined that people actually differ in their sensitivity to weather changes.

G. It is seriously doubted among the people who suffer from SAD.

    Who would win in a competition to memorize numbers, a chimp or a teenager? The teenager? Think again. Scientists have proved that chimps perform better than human beings when it comes to this kind of problem.

    Memory is our ability to learn something, save it and recall it when needed. Our memories are important to our sense of self, our personalities, and our ability to understand the world.

    {#blank#}2{#/blank#} There is short-term memory and long-term memory. Your short-term memory saves information for a few seconds or a few minutes. {#blank#}3{#/blank#} Long-term memory involves the information you try hard to keep, because it's meaningful to you-an example is data about family and friends. And then there is visual memory and sound memory. But these are not hard and fast. In fact, Scientists argue a lot about the nature of memory.

    {#blank#}4{#/blank#} Some memorize better with the help of pictures. Others are helped more by sounds. One thing's for sure though: If you can put the different kinds of memory together, there can be great results. {#blank#}5{#/blank#} At the same time, you could listen to recordings of the same group of words. These things may help when it comes to memorizing the words.

    Imagination and association can be useful too. By imagination, scientists mean picturing a word in your mind, while association means relating the word to something you already know.

A. So why not try pictures with English words?

B. Then how do chimps have better memories than us?

C. Scientists say that there are different types of memory.

D. We may have to rethink what we believe about human memory.

E. Scientists have also found that people memorize things in different ways.

F. For example, the time it takes to compare the prices of a few items in a store.

G. Short-term and long-term memory differ in the amount of information they can store.

How to Fight Laziness?

    Lazy people will never gain anything in life. However, laziness can be defeated once a few changes have been made in your mind. {#blank#}1{#/blank#} Many people lack sleep constantly, since they stay up too late and get up too early to prepare for work. These people have little motivation (动力) once they arrive home. Laziness works hand in hand with a lack of motivation and a tendency (趋势) to put off things. By adjusting your sleep schedule to provide a few more hours of meaningful rest, you can fight laziness throughout the day.

    Another way to fight laziness is to change your mind from passive to active. Some people treat their lives as if they were pushed from task to task. Others take a more positive approach viewing each task as a challenge they must overcome alone. {#blank#}2{#/blank#}

    Some people fight laziness by removing the temptations (诱惑) that surround them. A television in the living room may provide entertainment, but watching too much TV often contributes to laziness. {#blank#}3{#/blank#} Complete a few tasks and reward (回报) yourself with what you enjoy, such as a good dinner or a film.

    Laziness can also be a lasting problem at home. Couples and children may all have different energy levels, but laziness can be spread if not dealt with immediately. {#blank#}4{#/blank#} Be the first to collect and wash dishes after a meal. Others at home may finally follow your example and perform their own tasks. It is difficult to practice laziness when you are surrounded by motivated people.

    {#blank#}5{#/blank#} Enough exercise and a balanced diet can help you to develop a healthy lifestyle, thus enabling you to have more energy and help lift your spirits.
