If you're wondering when you might get the flu, a new study indicates you should keep an eye on your local weather report.

    According to a research published in the Journal of Clinical Virology, if you keep your eye on the weather and watch for the first major dip in the temperature, you can essentially mark your calendar in prediction for an outbreak the flu.

    To figure out how the weather and flu outbreak may be connected, researchers analyzed statistics of 20,000 people in an area over three seasons. The number of people who caught the flu was then compared with local weather data.

    After each season, the team noticed one consistent finding: The first really cold period with low outdoor temperatures and low humidity (湿度) was always followed by a week of a mass influenza outbreak.

    The researchers say that aerosol particles (气溶胶粒子) containing virus and liquid are more able to spread in cold and dry weather. So, in theory, if you sneeze or cough and the surrounding air is very dry, the air will absorb the moisture and the particles containing the virus keep spreading through the air for a longer period of time.

    Luckily there are ways to keep off the illness regardless of the weather. Washing your hands, coughing into the crook (弯曲) of your arm and getting vaccine (疫苗) are the best ways to prevent the flu from spreading. People over the age of 65, pregnant women and young children are at the highest risk of developing complications (并发症) related to the virus, according to the CDC.

    While everyone overthinks situations once in a while, some people are troubled by thinking all the time. Overthinkers rethink conversations they had yesterday, second-guess every decision they make, and imagine disastrous outcomes-all day. Their minds are like a movie where they imagine their car going off the road or they replay distressing events over and over again.{#blank#}1{#/blank#}

Keep the focus on problem-solving

    Keeping the focus on your problems isn't helpful-but looking for solutions is. If it's something you have some control over, consider how you can prevent the problem or challenge yourself to identify five potential solutions.

    If it's something you have no control over-like a natural disaster—think about the strategies you can use to cope with it.{#blank#}2{#/blank#}

    Schedule time for reflection

    Worrying about your problems for long periods of time isn't productive, but brief reflection can be helpful. Thinking about how you could do things differently or recognizing potential traps to your plan, could help you perform better in the future.

    Add 15 minutes of “thinking time” into your daily schedule. During that time let yourself worry, or think about whatever you want.{#blank#}3{#/blank#}

    Learning mindfulness skills

    It's impossible to rehash（反复推敲）yesterday or worry about tomorrow when you're living in the present. Mindfulness will help you become more aware of the here and now.

    {#blank#}4{#/blank#}There are classes, books, apps, courses, and videos available to help you learn mindfulness skills.

    {#blank#}5{#/blank#}

    Do this in your brain by changing your activity. Exercise, engage yourself in a conversation on a completely different subject, or work on a project that draws away your attention. Doing something different will put an end to the negative thoughts.

A. Change the channel.

B. Change your attitude.

C. Focus on the things you can control, like your attitude and effort.

D. Just like any other skill, mindfulness takes practice, but over time, it can decrease overthinking.

E. Overthinking can become such a habit that you don't even recognize when you're doing it.

F. There are four tips that can help you stop overthinking.

G. When your time is up, move onto something else.

    Ways to make a great first impression

    You've heard it a million times already, but it really does take but a few seconds to make that all-important first impression (印象). Here are some easy ways for you to impress your classmates or teachers.

    {#blank#}1{#/blank#}

Before you shake hands with somebody, make sure that your hands are clean. The handshake should not be too strong or weak. Most people use their right hands, unless they have a reason to use the left.{#blank#}2{#/blank#}

    Be on time

    When meeting someone for the first time, arriving on time is as important as breathing. You may have an excuse, but that will leave the person who hardly knows you with a bad impression.{#blank#}3{#/blank#}It's better to be hanging around the place than be stuck in traffic.

    Introduce yourself and ask for names

    Make sure you properly introduce yourself. Ask for their name in a polite way.  {#blank#}4{#/blank#}This will increase the chances of their remembering your name in the future. Always remember to stand up when greeting someone and be sure to introduce them to anyone you're with.

    Make good conversation

To get the most out of your discussion, try to find something common between the two of you. {#blank#}5{#/blank#}A person will feel more comfortable with someone they can relate to (产生共鸣).

A. Use body language

B. Have a proper handshake

C. Repeat the name and use it later in conversation.

D. As a general rule, plan to arrive about 30 minutes early.

E. It could be a similar taste in clothes or a common hobby.

F. You'll be in serious trouble if you leave them with a bad impression.

G. However, don't have your left hand in your pocket because this appears impolite.

    Mother's Day is a time of memory and celebration for Mom. The earliest Mother's Day celebrations date back to ancient Greece in honour of Rhea, the Mother of Gods. During the 1600s, England celebrated a day called “mothering Sunday”. Celebrated on the fourth Sunday of Lent(四旬斋)，“mothering Sunday” honoured the mothers England.

    During the time many of the England's poor worked as servants for the wealthy.AS most jobs were located far from their homes, the servants would live at the houses of their employers. On Mothering Sunday, the servants would have the day off and were encouraged to return home and spend the day with their mothers. A special cake, called the mothering cake, was often brought along.

As Christianity(基督教) spread throughout Europe, the celebration changed to honour the “Mother Church”—the spiritual power that gave them life and protected them from harm. Over time the church festival combined with mothering Sunday celebration. People began honouring their mothers as well as the church.

    In the United States Mother's Day was first suggested in 1872 by Julia Ward Howe as a day devoted to peace. Then in 1907 Ana Jarvis, from Philadelphia, began a campaign(运动) to establish a national Mother's Day. Ms Jarvis persuaded her mother's church in Grafton, Virginia to celebrate Mother's Day on the second anniversary of her mother's death, the 2nd day Sunday of May. By the next year Mother's Day was also celebrated in Philadelphia.

    Ms Jarvis and her supporters began to write to ministers, businessmen, and politicians demanding to establish a national Mother's Day. It was successful as by 1911 Mother's Day was celebrated in almost every state. President Woodrow Wilson, in 1914, made the official announcement that Mother's Day was a national holiday and it was to be held each year on the 2nd Sunday of May.

    While many countries of the world celebrate their own Mother's Day at different times throughout the year, there are some countries such as Denmark, Finland, Italy, Turkey, Australia, and Belgium which also celebrate Mother's Day on the 2nd Sunday of May.

    October 15^th is the Global Handwashing Day. Activities are planned in more than 20 countries to get millions of people in the developing world to wash their hands with soap. For example, donators (捐赠者) will give 150,000 bars of soap to schools in Ethiopia.

    Experts say people around the world wash their hands every day, but very few use soap at so-called important moments. These include after washing the toilet, after cleaning a baby and before touching food.

    Global Handwashing Day is the idea of the Public-Private Partnership for Handwashing with Soap. Partners include the United Nations Children's Fund, American government agencies, the World Bank and soap makers Unlever and Procter and Gamble. The organizers say all soaps are equally effective at removing disease-causing germs(细菌). They say the correct way to wash is to wet your hands with a small amount of water and cover them with soap. Rub(揉搓) it into all areas, including under the fingernails. Rub for at least twenty seconds. Then rinse well under running water. At last, dry your hands with a clean cloth or wave them in the air.

    The Partnership for Handwashing says soap is important because it increases the time that people spend in washing hands. Soap also helps to break up the dirt that holds most of the germs. And it usually leaves a pleasant smell. The Partnership for Handwashing also says washing with soap before eating or after using the toilet could save more lives than any vaccine(疫苗) or medicine. Hand washing could also prevent the spread of other diseases. When people get germs on their hands, they can infect(感染) themselves by touching their eyes, noses or mouths. Then they can infect others.

With more recognition than Halloween and less than Christmas, Valentine's Day as an imported festival faces a dangerous situation in China, where it's caught between forces of tradition and fashion. Valentine's Day has a natural enemy in China. And it is not the Chinese equivalent, which falls on the seventh day of the seventh month on the lunar calendar, usually around half a year away from Feb. 14. It is the Spring Festival, also known as the Chinese New Year, that will influence the Feast of Saint Valentine.

The real disagreement between East and West probably took place over a century ago, when China's door was forced open by Western powers and Chinese scholars supported westernization as a means to strengthen our nation's ability to compete.

The introduction of the solar calendar and Western measurements was both an acknowledgment of their influence and an effort to be accepted by the world order.

For a full century, we have had two systems running in parallel. When it comes to the eventual outcome, practicality usually beats all other concerns. Laws can help, such as the three traditional festivals of Tomb Sweeping, Dragon Boat and Mid­Autumn gaining legal status in 2008 and giving every Chinese citizen a day off, but laws cannot push what people have no feelings for. So, the celebration or boycott of imported holidays or homegrown ones should be no cause for worry. If they are irrelevant, no social media will change the public's mind; and if they are accepted, there must be a need which they happen to satisfy.

Since we have no global Qin Shihuang to force one system on every country, we can always rely on a dual (双重的) approach by which we share with the outside world on the one hand but preserve our own ways of life on the other.
