      The meaning of silence varies among cultural groups. Silences may be thoughtful, or they may be empty when a person has nothing to say. A silence in a conversation may also show stubbornness, or worry. Silence may be viewed by some cultural groups as extremely uncomfortable; therefore attempts may be made to fill every gap(间隙)with conversation. Persons in other cultural groups value silence and view it as necessary for understanding a person's needs.

        Many Native Americans value silence and feel it is a basic part of communicating among people, just as some traditional Chinese and Thai persons do. Therefore, when a person from one of these cultures is speaking and suddenly stops, what maybe implied(暗示) is that the person wants the listener to consider what has been said before continuing. In these cultures, silence is a call for reflection.

        Other cultures may use silence in other ways, particularly when dealing with conflicts among people or in relationships of people with different amounts of power. For example, Russian, French, and Spanish persons may use silence to show agreement between parties about the topic under discussion. However, Mexicans may use silence when instructions are given by a person in authority rather than be rude to that person by arguing with him or her. In still another use, persons in Asian cultures may view silence as a sign of respect, particularly to an elder or a person in authority.

Nurses and other care-givers need to be aware of the possible meanings of silence when they come across the personal anxiety their patients may be experiencing. Nurses should recognize their own personal and cultural construction of silence so that a patient's silence is not interrupted too early or allowed to go on unnecessarily. A nurse who understands the healing(治愈) value of silence can use this understanding to assist in the care of patients from their own and from other cultures.

    Peng Liyuan, wife of President Xi Jinping, has drawn extensive attention from people both at home and abroad for her charisma and grace. Accompanying her husband on his first overseas trip after becoming president, Peng Liyuan exhibited graceful demeanor, a pleasant personality and well-chosen dress, prompting people to coin the term “Liyuan style”.

Peng Liyuan, as one of China's best-known singers, was popular among Chinese people long before her husband became the president. Loved by her fans, she has been in touch with the people for years.

    “Liyuan style” is not only representative of a fashion idol, but also overpass cultural and diplomatic barriers. The beautiful handbags Peng has carried, and the plain but elegant and delicate dresses she has worn have become popular. Her choice of clothing, made-in-China instead of luxurious foreign brands, shows her belief in domestic dress designs.

But “Liyuan style” is not only about clothing and a woman's paraphernalia. It is also about diplomacy and promoting China's soft power. In Moscow, Peng visited a boarding school for orphans and children estranged (疏远) from their parents, encouraging them to strive for a better life, which brought out the maternal side of her character. In Tanzania, she donated sewing machines and school bags to women and children. And as a World Health Organization ambassador in the fight against AIDS, Peng is devoted to many public causes, including those relating to charity and healthcare.

    Some observers have already started saying that Peng's activities have become part of public diplomacy in China.

Also, “Liyuan style” has boosted the confidence of the Chinese people. Modem but not flashy, elegant but not arrogant, Peng has all the virtues of a Chinese woman and carries them to the international stage.

Since the 18th Party Congress and the annual sessions of the NPC and CPPCC, the country's new leadership has vowed to adopt a down-to-earth work style to connect with the people. Peng's plain but elegant style shows that thriftiness and an earthy style need not be drab and boring.

    So it can be said that Peng's first appearance on the international stage has kicked off well.

    I've learned that you have to make the choice if you want to get anywhere. If you just let other people decide what is going to happen for you, then all your goals and dreams may never be achieved.

    Everyone always says that studying abroad in college can change your life. I made the decision to experience it for myself during my junior year. I chose to study in the Dominican Republic. As it got closer to the deadline, an advisor told me I had received a scholarship from an alumni (校友) family foundation.

    During my first semester in the country I fell in love. I was becoming bilingual (双语的) but also learning so much about a new culture. I had begun working with a local grassroots organization, taking part in a project supporting an underdeveloped community just outside the city. My main role was to become aware of the issues facing populations such as these and support community education. I was in no way ready to leave this new life. I felt as if I needed more time to get what I wanted.

    As the next semester began, I realized again that I needed to take a chance. I got involved with a local boarding school for girls living in poverty. I first approached the head of the school to volunteer to teach music classes, asking for money from my college church. I could have never predicted the results of this small action. Another volunteer and I were able to put together a benefit (义演) to show off what the students had learned. We invited community members, friends and other students from local universities to support the girls. We also sold art that the students themselves had created to increase the funding (资助) of the arts program. I felt good when I left, knowing that I had laid the foundation for a good cause and bettered the lives of young girls.

    There will always be people that think they know what is best for you, but you ultimately know what you want in life. My time in the Dominican Republic changed my life by giving me the realization of how fortunate I am and the fact that there is always a chance to give back. You have to go after anything and everything you desire or there may be a missed opportunity. My trip to Santo Domingo taught me to take advantage of new possibilities.

    A Russian spacecraft traveling to the International Space Station Thursday had to make an emergency landing when a rocket engine failed to fire. It was the latest in a recent series of failures for the Russian space program, which is also used by the U.S. to carry its astronauts to the station.

    United States astronaut Nick Hague and Russian astronaut Alexei Ovchinin landed safely about 20 kilometers from Dzhezkazgan in Kazakhstan. The city is about 450 kilometers from the Russia's Baikonur space center, which Russia operates through an agreement with the Republic of Kazakhstan.

    Both the U.S. space agency NASA and Russia's Roscosmos reported that the two were quickly recovered from the landing area by rescue crews. A spokesman for Russian President Vladimir Putin said, "Thank God the crew is alive" after they had landed safely.

    About two minutes after launching, the three-stage Soyuz booster rocket suffered an unspecified failure of its second stage. Russia's TASS news agency said the capsule carrying the two men separated from the troubled rocket safely. This caused the capsule to drop very sharply into the Earth's atmosphere. Parachutes（降落伞）helped slow the returning capsule. Search and rescue teams were sent to recover the crew.

    Russia's RIA news agency reported that Russia has immediately put off all manned space launches after the failure. Roscosmos head Dmitry Rogozin said he had ordered a state commission to carry out an investigation into what went wrong. He said Russia will share all relevant information with the U.S.

    The TASS news agency said that the ISS crew has enough supplies and that the failed launch will not affect operations.

    The U.S. and other nations have depended on Russia to carry astronauts to the ISS since the retirement of the Space Shuttle program in 2011. In coming years, American aerospace companies SpaceX, with its Dragon 2, and Boeing, with its Starliner, are expected to return to space.

    The term "crocodile tears" refers to insincere sadness. This term has an etymology dating back several centuries. As early as the fourth century, crocodile tears are referenced in the literature with the meaning of insincere sorrow. It is said that crocodiles weep while eating their hunted animals because they are sad; however, this sadness is not honest.

    The term crocodile tears became widely popular after it was documented in a fifteenth-century book titled The Voyage and Travel of Sir John Mandeville, Knight. A passage from the book reads: "These crocodiles kill men and they eat them weeping."

    As you may already know, crocodilians(鳄目动物) likely feel bad about little—especially feeding. However, the assumption of the crocodile-tears metaphor may be true. In a 2007 paper published in BioScience titled "Crocodile Tears: And they eat them weeping", researchers observed 7 crocodilians in cages during feeding time at a reserve (4 caimans and 3 American alligators). The researchers observed the crocodilians outside of water at feeding stations to better find out whether tearing developed.

    Five of the 7 crocodilians developed something like tears in their eyes before, during or after feeding. The researchers suggest that these crocodile tears occur because a crocodilian hisses (发出嘶嘶声) while it eats, and this hissing forces air through the spaces in the bone behind the nose and out the eye, in the process picking up nasolacrimal secretions (鼻泪管分泌物.)

    In humans, crocodile tears is a medical condition that causes a person to tear up while eating. Crocodile tears typically occur because of a temporary loss of facial control due to damage of the facial nerve. Specifically, when the facial nerve grows again, it does so incorrectly thus resulting in tears during chewing food.

Nobody likes an old idiot(傻子).Developing a sense of humor is part of becoming a mature,emotionally healthy individual.Laughter is good for the soul,which builds friendships and relieves stress.It serves as the glue for social situations and as an ice-breaker for sadness and boredom.If you've ever been told to "lighten up" or "chill out",you should save the blue attitude for serious situations and develop your sense of humor.

Forgive the accident.A sudden fall is humorous not because we like to see people fall,but because it surprises us.From a spilled water glass in a meeting to Aunt Rae's teeth coming off in the Thanksgiving Day,the embarrassment of accidents can be relieved by humor and a helping hand.After making sure that nobody is hurt,forgive accidents with a chuckle(咯咯地笑) rather than a scolding.

Look for the unexpected.The kid who used to look at you with his eyes closed during a test had the idea.Parents who serve green eggs and ham to their children on graduation day get the idea.Unexpected action lightens the atmosphere and relaxes people.
