A day in the life of 18-year-old David Lanster is full of typical teenage stuff: school, baseball practice, homework. And then he starts cooking.

    “Some nights I'm up until I am making pies, or even later if we're braising (蒸) beef,” said the student at Ransom Everglades High School in Florida, US.

    For the past year, Lanster and Kelly Moran, his classmate, have been hosting fancy dinner parties at Lanster's parents' home. Their meals have 17 courses and are all made by them.

    Their guests used to give them gifts to thank them, until the pair decided to do something nice for charity (慈善).

    “We got some really great Miami Heat tickets, a nice watch, and many kitchen gadgets (小物件),” Lanster said. “But we wanted to make this something positive for people other than us.”

    Lanster and Moran focused on Common Threads, a charity that aims to teach kids in poor communities (社区) to cook and make healthy eating choices.

    The young cooks ask their guests to give however much they want as payment for their meals. It all goes to Common Threads because Lanster's parents cover their food costs. After their last 12-person event, Lanster and Moran gave $1,600 (10,600 yuan) to the charity.

    Now, they're taking their show out of the kitchen and on the road. Lanster and Moran have started to organize private dinner parties with a similar model: the host pays for the ingredients, and the guests make a donation to a charity of their choice.

    Without formal (正规的) training, Lanster said he had been interested in cooking since he helped his mom in the kitchen when he was very young. He learned how to cook by reading cookbooks and watching TV programs.

    Outside the kitchen, the two are busy preparing their college applications.Neither is sure what they will do in the future, but they've promised their parents that they'll leave professional cooking alone until they finish school.

    The wonderful experiment I am going to introduce proves that air is just all around and that it presses down upon us. Air pressure is a wonderful force. When you swim underwater, you can feel water push down your body. The air all around you does the same. However, your body is so used to it that you do not notice this. The pressure is caused by a layer of air called the atmosphere. This layer surrounds the Earth, extending to about five kilometers above the Earth's surface.

    The following experiment is an easy one that you can do at home. But make sure that you are supervised, because you will need to use matches. Now for the experiment！

    What you need:

·A hard-boiled egg without the shell

·A bottle with a neck slightly smaller than the egg

·A piece of paper

·A match

Method:

1） Check that the paper will sit firmly on the neck of the bottle.

2） Tear the paper into strips and put the strips into the bottle.

3） Light the paper by dropping a burning match into the bottle.

4）Quickly sit the egg on the neck of the bottle.

Result:

    Astonishingly, the egg will be sucked into the bottle. Your friends will be amazed when you show them the experiment. But be careful when you handle matches.

    Why it happened

    As the paper burns, it needs oxygen and uses up the oxygen（air）in the bottle. The egg acts as a seal in the neck of the bottle, so no more air can get inside. This reduces the air pressure inside the bottle. The air pressure must equalize, so more air from outside must enter the bottle. The outside air pressure against the egg and then the egg is pushed into the bottle! This proves that air is all around and that it is pressing down on it.

    Peruvian novelist, Mario Vargas Llosa, who received Nobel Prize for Literature in 2010, is one of the central writers in Latin America, but he began his literary career in Europe.

    Mario Vargas Llosa was born in Arequipa, but from age one he lived in Cochabamba, Bolivia, where he was brought up by his mother and grandparents after his parents separated. However, Vargas Llosa once said that "I feel very much an Arequipan"．He also spent some time in Piura, northern Peru (1945～1946)．

    Vargas Llosa attended Leoncio Prado Military Academy (1950～1952), and Colegio Nacional San Miguel de Piura (1952), Peru． In 1955 he married Julia Urquidi; they divorced in 1964.From 1955 to 1957 Vargas Llosa studied literature and law at the University of San Marcos, Peru. He then attended post-graduate school at the University of Madrid, Spain, where he received his Ph.D.in 1959.

    In the 1950s, while still a student, Vargas Llosa worked as a journalist for La Industria. His first collection of short stories, LOSJEFES, appeared in 1959."I liked Faulkner but I imitated Hemingway, "he said later. Vargas Llosa moved to Paris because he felt that in Peru he could not earn his living as a serious writer. Although the boom of Latin American fiction in the 1960s opened doors to some authors for commercial success, the great majority of Peruvian writers suffered from the problems of the country's publishing industry. In France Vargas Llosa worked as Spanish teacher, journalist and broadcaster. From the late 1960s Vargas Llosa worked as a visiting professor at many American and European universities. In 1970 Vargas Llosa moved to Barcelona and five years later he settled back in Peru. Most of his novels are set in Peru.

    In addition to the Nobel Prize, Vargas Llosa has received many other honors. Among the most notable are Leopoldo Alas Prize (1959), Peruvian National Prize (1967) and Miguel de Cervantes Prize (1994).

    Have you ever run into a careless cell phone user on the street? Perhaps they were busy talking, testing or checking updates on WeChat without looking at what was going on around them. As the number of this new "species" of human has kept rising, they have been given a new name — phubbers (低头族).

    Recently, a cartoon created by students from China Central Academy of Fine Arts put this group of people under the spotlight. In the short film, phubbers with various social identities bury themselves in their phones. A doctor plays with his cell phone while letting his patient die, a pretty woman takes selfie(自拍照) in front of a car accident site and a father loses his child without knowing about it while using his mobile phone. A chain of similar events eventually leads to the destruction of the world.

    Although the ending sounds overstated, the damage phubbing can bring is real. Your health is the first to bear the effect and result of it. "Constantly bending your head to check your cell phone could damage your neck," Guangming Daily quoted doctors as saying. "The neck is like a rope that breaks after long-term stretching." Also, staring at cell phones for long periods of time will damage your eyesight gradually, according to the report.

    But that's not all. Being a phubber could also damage your social skills and drive you away from your friends and family. At reunions with family or friends, many people tend to stick to their cell phones while others are chatting happily with each other and this creates a strange atmosphere, Qilu Evening News reported.

    It can also cost you your life. There have been lots of reports on phubbers who fell to their death, suffered accidents, and were robbed of their cell phones in broad daylight.

    A man going abroad to work leaves his young lady crying. "Don't worry, I will write to you every day," he said. For years he did write to her. But since he was happy with his job, he had no immediate plans of going home. One day, he received a wedding invitation. His girlfriend was scheduled to be married. To whom? To the mailman bringing regularly the letters of her boyfriend! Indeed, distance does make hearts struggle.

    While presents are important, love demands what is basic: presence of the beloved.

    Martha was busy with her job. She believed she had to work harder because she loved her father who had serious disease. She had to provide for his expensive medicine. Her brothers and sisters meanwhile stayed with their father most of the time. They bathed him, sang for him, spoon­fed him or simply kept him company.

    One day Martha was hurt. She overheard her father telling her mother, "All our children love me except Martha." "How can this be?" Martha thought. "Am I not the one killing myself in my work to earn money to buy for his medicine? My brothers and sisters do not even provide their share in the expenses as much as I do."

    One night, as Martha was as usual late in going home, she peeped for the first time in the room where her father was lying. She noticed that her father was still awake. She decided to come close at his bedside. Her father held her hands and said, "I miss you. I don't have much time. Stay with me." And she stayed with her father holding his hand the whole night.

    The next morning Martha said to everyone, "I have taken a leave of absence. I would like to be with my father. I will bathe him and sing for him from now on." Her father had a beautiful smile. He knew this time Martha loved him.

    As children, we need the assuring presence of our loved ones. Adult people need no less.
