Barack Obama was born on August 4, 1961 in Honolulu, Hawaii. His father came to America from Kenya, which is a country in Africa. His parents, Ann and Barack, met when they were students at the University of Hawaii. Since Barack had the same name as his father, young Barack went by the nickname “Barry”.

    In 1979, after he finished high school, Barry went to Occidental College in Los Angeles, California. There, he started to learn about his African roots and decided to use his African name, Barack. After two years in L.A., he went to Columbia University in New York City to study politics.

    After college, he moved to Chicago, Illinois, where he worked to help poor people in his city. He traveled to Africa to meet his grandmother and cousins for the first time. He went back many times over the years to visit with his family and learn about where he came from. At work, he met a lawyer named Michelle Robinson. They worked together in a big law firm. Then he left Chicago to go to Harvard Law School in Cambridge, Massachusetts. He did very well in law school.

    After he was done with school, Barack moved back to Chicago and in 1992 he married Michelle. He worked as a lawyer, devoted to helping poor people for free who had been treated unfairly. He worked hard to get the people he helped to vote.

    He made many people believe that their votes were important, and helped them feel like they could make a difference.

    There is a story about a man who lost his legs and left arm in an accident. After the accident, only a finger and thumb on his right hand remained.

    He was a brilliant, creative, and educated man. He had gained a lot of experience while traveling around the world, so he became very depressed after his accident. He was afraid that he would spend the rest of his life suffering and would no longer be able to spend his life in a meaningful way. Then, he realized that he still had partial function of his right hand and could still write even though it was very difficult. An idea occurred to him. “Why not write to other people who need encouragement?”

    He wrote to the prison ministry about sending letters to the prisoners. The prison minister replied, “Writing to the prisoners is acceptable, but your letters will not be answered.”

    Filled with excitement, the man knew he could write his letters. He began sending one-way messages of God's love, hope, strength, and encouragement. He wrote twice a week, testing his strength and ability to the limit. He poured his heart and soul into his words and shared his experience, sense of humor, optimism, and faith.

    It was difficult to write those letters, especially without hope of a reply. One day he received a letter from the prison ministry. It was a short note from the officer who monitored and checked the prison mail.

    The letter said, “Please write on the best paper you can afford. Your letters are passed from cell (囚房) to cell until they literally (逐字地) fall to pieces!”

    No matter what circumstances life may present, we all have unique experiences, abilities, and God-given talents. We can discover ways to reach others who desperately need messages of encouragement and strength.

    Mom wanted only one thing for her birthday. “Can you find me another copy of this song?” she asked, and handed me a worn-out cassette tape (磁带). I knew exactly what was recorded on it: My Redeemer (救世主). I heard the song played at least a thousand times while growing up. After so many years, the cassette tape was too worn out to be used. I promised her I would find a replacement.

    My Redeemer became Mom's favorite song after my younger brother Tim was killed by a drunk driver in 1973. The only thing that helped her calm down was the soulful sound of My Redeemer from the local radio station.

       We recorded it on a cassette tape so she could listen to it any time she wanted but none of us knew who the soloist (独唱者) was. These days, I thought the song would be easy to find out. I went home and searched the Internet. Several songs with that title popped up, but none of them was the one Mom loved. I got frustrated.

    Mom's birthday drew near and then one day, I was driving home, listening to our local radio station. A familiar tune came on. It was My Redeemer! As soon as I could, I phoned the station. I got a line on the soloist, who was called Alan Parks. I typed his name into Google and found his home number in South Carolina. Minutes later, I was telling him how much his recording meant to Mom. He offered to ship two CDs out to me personally. I gave him my address.

    'Red Lion, Pennsylvania?' he said. 'Do you know the Logans?' 'They are our neighbors!' 'I've been friends with them for 25 years,' Alan said. 'They'll be at my concert at York Gospel Chapel on April 17th. Would you and your mom come too” We sure would. Mom was excited to hear Alan sing My Redeemer to her, live in concert —on the evening of her 87th birthday.

    As I was thinking about language learning the other day, the image of baking bread came into my mind. I compared some of the exercises and drills that we put ourselves through in order to learn a language to the various ingredients that go into baking a loaf of fresh bread.

    Real language learning takes place in human relationships. No one sits down and eats a cup of flour, even if he is hungry and in a hurry. You don't become bilingual（双语的）by learning lists of vocabulary. You don't become a speaker of a language by memorizing verb conjugations（动词的词形变化）and agreement rules. You become bilingual by entering a community that uses that other language as its primary means of communication.

    I am not suggesting that we can make bread without ingredients. Flour is necessary, as are yeast, salt, water and other ingredients. Vocabulary is part of any language and will have to be learned. Grammatical rules exist in every language and cannot be ignored. But merely combining the appropriate ingredients in the recommended proportions does not result in bread. At best, you only end up with a ball of dough（面团）.

    In order to get bread, you have to apply heat to the dough. And in language learning, that heat comes from the community. Anyone who has learned a second language has experienced that heat. It creeps up your neck when you ask the babysitter, “Have you already been eaten?” when you meant to say, “Have you already eaten?” When you try to say something quite innocent and the whole room bursts into laughter, you are experiencing the heat that turns raw dough into good bread.

    Remember the old saying, “If you can't stand the heat, get out of the kitchen”? This is where language learning often breaks down because we find the heat uncomfortable and we stop the baking process. In other words, we can't stand the heat, so we get out of the kitchen.

    However, the language learner who stays in the kitchen—in the heat—until the combined ingredients are thoroughly transformed will enjoy the richness of a quality loaf of bread. He said that he did not “get out of the kitchen” at the critical moment when the oven seemed too hot. The dedicated language learner knows that becoming bilingual cannot be achieved without the heat!

    My challenge for you is this: to read a book for 15minutes every single day for a month.

    Let me explain a bit, by telling you where the challenge came from. I have many things in common with my dad, like music taste and sense of humor, but sadly reading isn't one of them. I can happily spend a whole day with a book, but my dad can't read a book for longer than about 5 minute. He reads emails, websites and papers for work, but not book. He's busy, so I think sitting down to read for just 15minutes a day is a good way to relax and to introduce him to reading.

    My dad is not the only person who avoids book. I know lots of people would rather relax on their computers or in front of the TV. Everyone is different and has their own interests, but I think there are lots of benefits to reading, which screen﹣based activities don't have.

    Firstly, it's better for your eye. Looking at screens can be very stressful for your eye muscles, and clearly you should avoid looking at screens for an hour before bed, to get a good night's sleep.

    One thing I personally love reading, is being transported to another world﹣I often forget the time or things around me! Reading is a great way to switch off before you go to bed, because you think more about the world of the book, rather than the real world, so you can truly relax. I know you can be transported to a different world in a film or a TV show, but I think books do it better.

    I also enjoy hearing what people are doing and finding out what they think. Reading gives me the chance to get to know hundreds of new people! It also teaches you to see things from other people's point of view, and understand other people's decisions or opinion. With a book, you can hear everything a character is thinking or feeling﹣you really can be inside someone else's head!

    So give it a go! Take 15 minutes when you are waking up, going to bed, eating lunch, or having a coffee. If you read a lot, why not try 15 minutes of an English book, or pass the challenge on to someone else？ Good luck, and happy reading!

    If English means endless new words, difficult grammar and sometimes strange pronunciation, you are wrong. Haven't you noticed that you have become smarter since you started to learn a language?

    According to a new study by a British university, learning a second language can lead to an increase in your brain power. Researchers found that learning other languages changes grey matter. This is the area of the brain which processes information. It is similar to the way that exercise builds muscles.

    The study also found the effect is greater when the younger people learn a second language. A team led by Dr. Andrea Mechelli, from University College London, took a group of Britons who only spoke English. They were compared with a group of "early bilinguals" who had learnt a second language before the age of five, as well as a number of later learners.

    Scans showed that grey matter density (密度) in the brain was greater in bilinguals than in people without a second language. But the longer a person waited before mastering a new language, the smaller the difference.

    "Our findings suggest that the structure of the brain is changed by the experience of learning a second language," said the scientists.

    It means that the change itself increases the ability to learn.

    Professor Dylan Vaughan Jones of the University of Wales, has researched the link between bilingualism and maths skills. "Having two languages gives you two windows on the world and makes the brain more flexible (灵活的)," he said. "You are actually going beyond language and have a better understanding of different ideas."

    The findings were matched in a study of native Italian speakers who had learned English as a second language between the ages of two and thirty-four. Reading, writing, and comprehension were all tested. The results showed that the younger they started to learn, the better. "Studying a language means you get an entrance to another world," explained the scientists.
