There is an English saying that “Laughter is the best medicine.” Until recently, few people took the saying seriously. Now however, doctors have begun to look into laughter and the effects it has on the human body. They have found that laughter can really improve people's health.

    Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their hearts, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise. It increases blood pressure, makes the heart beat quicker and makes people breathe deeper; it also works on several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial.

    Other tests have shown that laughter appears to be able to reduce the effects of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group that tolerated（忍耐）the pain for the longest time was the group which listened to a funny program. The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemical in the brain which diminishes both stress and pain.

    As a result of these discoveries, some doctors in the United States now hold laughter clinics, in which they help to improve their patients' condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.

    High school plays a major role in shaping up your future and your whole development. Extracurricular (课外的) activities along with the studies can be very helpful. Make yourself take part in various activities and at the same time try to stand out in your studies. When you move out to college these efforts that you put in may count for a lot.

    High school is not just about books or classes. Schools always provide opportunities for students to socialize (社交). There are various group tasks designed which allow the students to learn to work together.

    High school is the right time for you to discover yourself and bring out some of your hidden talents. In your lessons, you may find that you are better at English than you were earlier or have grown an interest for Math. High school also provides many other opportunities for students to take part in. These help develop leadership skills and management skills at an early age, which in turn is a way of preparing students to manage and plan their careers (事业) better.

    Balancing all activities is an experience in time management. If you have taken up a part-time job along with your high school you would have to arrange your time for studies, and extracurricular activities. Such management can go a long way in teaching you to manage things better when you take up a job. Moreover, they help build your character. You would be better prepared for additional stress that you may feel sometimes.

    When at high school you should pick up your classes wisely. Depending upon what you like and your career plan you should choose suitable classes. Doing something that you hardly like may get you very low grades as well as lose valuable time. Take up interesting and challenging classes that would allow you to put in those extra efforts.

I have happy memories of trips to Europe, but my trip to Romania (罗马尼亚) was unique. When I was there as recalled, it was like being in a "James Bond" movie. My husband was born there, but his family sent him to study in Italy. Before he left, his mother told him, "As long as I write in pencil, don't come back. When I write to you in pen, it's safe to return." But she never wrote in pen.

    My husband lived a poor life in Italy. He applied to go to America, but there was a limit in number and he was rejected. He was accepted by Canada, though, and from Calgary he jumped onto a train to San Francisco. There he stayed —illegally. He became a US citizen when we got married. By then he was a charming European with a Romanian accent and the manners of a prince.

    With seven years' experience in America, a US passport, and two children later, he felt it was safe to visit Romania. He hadn't seen his mother, two sisters, and two brothers since he was sixteen. We flew to Munich, Germany; picked up the German-made car we had purchased in the States; and drove to Romania via Austria and Hungary. When we reached Bucharest, the capital city of Romania, his family was waiting outside his sister's house to greet us. After a long time of hugging, kissing, and crying, his family also hugged me, the American wife with two young children. They had great interest in me. Few Americans visited Romania at that time, and most Romanians had little chance to travel. I had brought an English-Romanian dictionary with me and managed to communicate, using only nouns, with no verbs. My Romanian improved, and the family's stock of English words increased, but mostly I spoke in broken, New York-accented Romanian. The sisters loved their gifts of skirts and purses, the brothers loved the radios, and the children loved the candy. We made side trips to the Black Sea and enjoyed sightseeing in beautiful mountains. Dining at outdoor cafes to the music of violins was fantastic with fancy flavor, but nothing was as special as family dinners.

    Romania didn't have many dry cleaners. Most homes had old-fashioned washing machines but no dryers, and it was a hot summer. My husband's relatives didn't want to risk dirtying their clothes. Their solution was as simple as it was shocking: the women only wore their bras(胸罩) and slips (衬裙) at dinner table. The men were eating without shirts. They all had jobs, so time was precious. Having dinner without proper clothes was a small inconvenience compared with the effort of washing clothes —at least in my husband's home, perhaps all across Romania. I, of course, having just met them, ate fully clothed. I washed my clothes by hand and hung them outdoors to dry.

On the last night of our three-week stay, we had a large family dinner. I was tired of washing my clothes. So I pulled my dress over my head and placed it on the chair behind me. All men and women applauded for my action. Even with my poor Romanian, I understood that they were saying, "She's part of our family now."

My children were 4 and 5 at the time, but they still have memories of that trip. They know how to say, "Good morning." and "There are apricots (杏子) on the tree." I can still say, "Do you speak Romanian?" and "I swim in the Black Sea." But most of all, I remember sitting at a long dining-room table in my bra, enjoying meatballs with fresh garlic (大蒜).

    One morning more than thirty years ago, I entered the Track Kitchen, a restaurant where everyone from the humblest(卑微的) to the most powerful came for breakfast. I noticed an empty chair next to an elderly, unshaven man, who looked somewhat disheveled. He was wearing a worn-out hat and was alone. I asked if I might join him. He agreed quietly and I sat down to have my breakfast.

    We cautiously began a conversation and spoke about a wide range of things. We never introduced ourselves. I was concerned that he might have no money and not be able to afford something to eat. So as I rose to go back to the counter and buy a second cup of coffee, I asked,

    “May I get you something?”

    “A coffee would be nice.”

    Then I bought him a cup of coffee. We talked more, and he accepted another cup of coffee, Finally, I rose to leave, wished him well, and headed for the exit. At the door I met one of my friends. He asked,

    “How did you get to know Mr. Galbreath?”

    “Who?”

    “The man you were sitting with. He is chairman of the Board of Churchill Downs.”

    I could hardly believe it. I was buying, offering a free breakfast, and feeling pity for one of the world's richest and most powerful men!

    My few minutes with Mr. Galbreath changed my life. Now I try to treat everyone with respect, no matter who I think they are, and no matter another human being with kindness and sincerity.

    Engineers have put a huge garbage collector to gather plastic material in the Pacific Ocean between California and Hawaii, the world's largest spread of garbage, twice the size of the state of Texas.

    The Ocean Cleanup organization created the collector. The group's founder, Boyan Slat, an inventor born in 1994, was just 16 when he was moved to clean up the oceans when he was on a dive and saw more plastic bags than fish

    Last Saturday, a ship pulling the pipe-shaped floating barrier left San Francisco. Attached to it is a screening skirt that hangs three meters down in the water. The screen is designed to collect the plastic as it moves through the water. Sea animals can safely swim under the barrier.

    The cleanup system also comes with lights powered by the sun, cameras, and other special devices, so the system can communicate its position at all times. That way a support ship can find it every few months to remove the plastic that has been collected.

    Shipping containers will hold all the plastic gathered, including bottles and fishing equipment and are expected to be back on land within a year. Then the plastic will be recycled. The free-floating barriers are made to survive extreme weather conditions and damage from continual use. They will stay in the water for twenty years, thus collecting 90% of the garbage in the area.

    The Ocean Cleanup has received $ 35 million in donations to pay for the project, hoping to put 60 free-floating barriers in the Pacific Ocean by 2020. "It's important to turn off the taps on plastic entering the ocean, but I also think people can do more than one thing at a time to deal with this problem," Slat said.

    I'm a real book lover. Every time my friends visit me, my nose is buried in a book. Wherever I go, I always have a book with me. Novels, history books, stories about people, journals and news­I read them all and I've learnt a lot, too. For example, many things in life happen for the best even if we don't like or understand them.

    Why is reading such an enjoyable pastime for me? I probably first learned about it from my parents. My mother read to me at night in my childhood and bought me picture books. The greatest gift she has given me is a love for reading. And it will be a life-long habit.

    No one ever asked me why I liked to read. They just saw me and asked, "Oh? Is that for school work?" And I just shook my head, "No. It's just for fun." While reading a good book, I can totally forget myself and fly to another world. It's like exploring through someone's eyes, which is just as exciting as watching a movie.

    Reading is also necessary in order to learn about writing, to improve my use of words and phrases and broaden my knowledge. What a pity to see our imagination disappear, for we don't exercise it often. Reading can even be good for one's health, I think. Everyone should read sad stories that make us cry and also books with humor that make us laugh out loud!
