Yesterday I went to the nursing home to visit my grandma. She just got out of the hospital recently where she had some serious operations. I wanted to surprise her after work so I stopped by for a quick visit.

    When I got there, she was so happy to see me. We hugged, kissed and exchanged greetings. Then I heard a woman crying. It was my grandma's roommate. The curtain was drawn so I could not see her. She started calling out a name that wasn't mine but she was certainly talking to me, begging me to go to her side of the room.

I ignored her at first and continued talking with my grandma. Then she started begging and saying, "Please, come to see me!" So I went to see her.

    When I drew the curtain back, she looked so old but flashed me the biggest smile! She opened her arms wide for me to hug her so I bent low and gave her a hug. I sat on her bed and talked with her for a few minutes. She kept calling me by the other name, but I did not correct her. She told me stories as if I had been there when they happened.

Finally I went back to talk with my grandma. Then the woman started crying again, saying, "Please, come back." She finally slept.

    I stopped by the nurse's station and the nurse told me that the lady suffers from Alzheimer's (老年痴呆症). I mentioned the name she had called me. The nurse told me it was the lady's daughter's name. Then I understood why she wanted me to go to visit her.

    We will all get old some day. Some of us will have broken minds like the lady and some of us will have broken bodies like my grandma. As I was leaving, I promised I would go back and visit the lady, even after my grandma moved back to her home.

    Some international languages are widely used for many purposes. Some minority languages will die out and some nations tend to keep minority languages. I reckon that most common used international languages ease our life quality and communication with different nationalities. On the other hand, we need to help improve minority languages.

    There are many languages in the entire world but two or three minority languages die out each year. Some countries try to save dying languages. For instance, Australian Government created a project to save the language and culture of Maori who are Australian aborigines. And there are other projects to keep minority languages such as American Indian language.

    However, the worldwide job market usually requires candidates who can speak English or other international languages. People who cannot speak lingua franca (共通语) could hardly be promoted at work. For example, some companies need an employee who can deal with foreign companies. So most people tend to learn at least one international language that helps them to find a better job.

    Therefore, world needs one common lingua franca that should be spoken in any country. Consequently, one common language should be a required subject in every school. So anyone speaking one common language can travel without worries to any point of the world and trade their products. People will not be forced to learn many languages.

    In conclusion, we should help minority nations to keep their languages for the cultural diversity. To ease the worldwide communication among nations, we should create a common language and provide courses of it. As a result, no one will face a language issue.

    All over the world people enjoy sports, Sports help to keep people healthy and happy, and to live longer.

    Many people like to watch others play games. They buy tickets or turn on their TVs to watch the games. Often they get very excited when "their" player or team wins.

    Some sports are so interesting that people everywhere go in for(参加)them. Football, for example, has spread (展开)around the world. Swimming is popular in all countries near the sea or in those with many rivers. What fun it is to jump into a pool or lake, whether in China, Egypt or Italy! And think of people in cold countries. Think how many love to skate or ski(滑雪)in Japan, Norway or Canada.

    Some sports or games go back thousands of years, like running or jumping. Chinese wushu, for example, has a very long history. But basketball and volleyball are rather new. Neither one is a hundred years old yet. People are inventing new sports or games all the time. Water-skiing is one of the newest in the family of sports.

    People from different countries may not be able to understand each other, but after a game together they often become good friends. Sports help to train(培养，训练)a person's character(性格，品格).One learns to fight hard but fight fair, to win without pride and to lose with grace(胜不骄，败不馁).

Museum lets visitors walk in the shoes of a police officer

Police shows on TV are filled with high- speed car chases and crimes solved in a few minutes. But that's not a typical day for a real- life police officer. To get a more accurate picture, head to the National Law Enforcement Museum in Washington. Exhibits there invite visitors to use their senses of sight, hearing, touch and smell to gather information the way police do.

Let's look at a few exhibits.

K-9 Units

See a video of how dogs are trained to join K-9 Units. Test your ability to smell and identify various scents(气味). Learn which kinds of dogs are better at tracking bad persons while others are better at sniffing out dangerous goods.

The Web of Law Enforcement

You' ll quickly learn that crime- solving is a team effort, not only within one department, but among organizations across the country. Inspection Service is just one of the law enforcement groups helping local police when needed. For example, six organizations worked together on a national park graffiti(涂鸦) case.

Five Communities

Every community is different. Learn how the needs and challenges of five communities are being dealt with. These communities goals are to develop programs, while increasing trust between local people and police. What might work in your neighborhood? There's a place for visitors to share their thoughts.

The Training Simulator

Those aged 12 and older can try the same training scenarios(方案) and . equipment used in professional law enforcement classes in which police try to resolve difficult situations. Short videos test participants' abilities to observe accurately and think quickly before reacting.

The exercises give an understanding of what officers face on a daily basis.

" Many kids first think it's like a video game," said Alan Davis, an educator and New York police officer." They soon realize that real- life decision- making in a second isn't easy, and they freeze. For real police there are no second chances."
