Article: Looking through a magazine in a waiting room recently, I came across an article with the title "My top five most precious possessions".It was just a few lines of text with pictures, but it caught my imagination. It's interesting how inanimate objects can take on such significance and become woven into a person's, and sometimes a whole family's life history. Anyway, the article had me considering what my most precious possessions are. It was difficult to choose only five, but here are mine: An old cardboard box filled with my children's baby photos. A yellow pocketsized birthday book of special things (poems, pictures of flowers and trees, etc) given to me by my dad when I was probably about seven or eight years old. A 21st Birthday card from my mum. In it she's written her congratulations, her love, and her hopes for my future. She died not long after, when I was in my early twenties. A few ancient but very beautiful botany books that were once my great grandmother's. She was a botanist in a time when it was ly unusual for women to be qualified in this field and I think she was probably a remarkable and very interesting woman. I'd like to have known her. A brooch left to me by my muchloved grandmother. It was given to my great grandmother (her mother) by my great grandfather on his return from World War I. It is not worth anything in terms of money. However, it not only stands for a link between four generations of women, but it is also a reminder of one young man's return from World War I. How about you? I'd love to hear what you feel are your most precious possessions.

Article: Most middle school students find it boring to learn math. But students in Yet Sen Middle School in New York, US, don't think so. Why? Because they are in the school of One Program, which asks students to work on their own or in small groups on computers to have math lessons. "The program gives the students a new learning style. No traditional classroom can compare with it. We give each lesson according to the students' interest and their strong and weak points, "said Joel. Klein, the school's headteacher, "We're looking for a new way that interests students. " Students enjoy these math lessons, especially lessons with video games. They must find out the answers to math problems to get through the game. One such game is Dimension M. As students move through mazes with their keyboards, some questions come up. Caleb Deng had to answer the question: What is 5+(6x3)? He _ on paper quickly because there was just a minute left to play. "I was right, "said Deng, 14, as he ended the game with a high score . "This really makes math lessons more exciting, since we are fighting to learn better. "

Article: My heart sank when the man at the immigration counter gestured to the back room. I was born and raised in America, and this was Miami, where I live, but they weren't quite ready to let me in yet. "Please wait in here, Ms. Abujaber," the immigration officer said. My husband, with his very American last name, accompanied me. He was getting used to this. The same thing had happened recently in Canada when I'd flown to Montreal to speak at a book event. That time they held me for 45 minutes. Today we were returning from a literary festival in Jamaica, and I was shocked that I was being sent "in back" once again. The officer behind the counter called me up and said, "Miss, your name looks like the name of someone who's on our wanted list. We're going to have to check you out with Washington." "How long will it take?" "Hard to say...a few minutes," he said, "We'll call you when we're ready for you." After an hour, Washington still hadn't decided anything about me. "Isn't this computerized?" I asked at the counter, "Can't you just look me up?" "Just a few more minutes," they assured me. After an hour and a half, I pulled my cell phone out to call the friends I was supposed to meet that evening. An officer rushed over. "No phones!" he said, "For all we know you could be calling a terrorist cell and giving them information." "I'm just a university professor," I said. My voice came out in a squeak. "Of course you are. And we take people like you out of here in leg irons every day." I put my phone away. My husband and I were getting hungry and tired. Whole families had been brought into the waiting room, and the place was packed with excitable children, exhausted parents, and even a flight attendant. I wanted to scream, to jump on a chair and shout: "I'm an American citizen; a novelist; I probably teach English literature to your children." After two hours in detention , I was approached by one of the officers. "You're free to go," he said. No explanation or apologies. For a moment, neither of us moved. We were still in shock. Then we leaped to our feet. "Oh, one more thing," he handed me a tattered photocopy with an address on it, "If you aren't happy with your treatment, you can write to this agency." "Will they respond?" I asked. "I don't know--I don't know of anyone who's ever written to them before." Then he added," By the way, this will probably keep happening each time you travel internationally." "What can I do to keep it from happening again?" He smiled the empty smile we'd seen all day, "Absolutely nothing." After telling several friends about our ordeal, probably the most frequent advice I've heard in response is to change my name. Twenty years ago, my own graduate school writing professor advised me to write under a pen name so that publishers wouldn't stick me in what he called "the ethnic ghetto"--a separate, secondary shelf in the bookstore. But a name is an integral part of anyone's personal and professional identity--just like the town you're born in and the place where you're raised. Like my father, I'll keep the name, but my airport experience has given me a whole new perspective on what diversity and tolerance are supposed to mean. I had no idea that being an American would ever be this hard.
