Have you ever noticed what happens to an idea once you express it?Just talking about it or writing it down causes you to make it clear in your own mind.How can you use this to increase your brain power?Start writing.

    By putting thoughts into words,you are telling yourself the logic behind what you think,feel,or only partly understand.Often,explaining a thought is the process of understanding.In other words,you increase your brain power by exercising your “explain power”.

    Another benefit of writing is that it helps you remember.Many,if not most,highly productive people are always taking notes.You can try keeping it all in your head,but if you keep a journal of your ideas,the next time you're working on a big project,you'll probably have more success.

    Want to understand a topic?Write a book about it.That's an extreme example,but if you are learning something new,write a letter to a friend about it,and you will understand it better.Want to invent something?Write an explanation of the problem—why you want to solve it,and why it is worth solving,and you're halfway there.

    Writers don't always write because they clearly understand something beforehand.Often,they write about something because they want to understand it.You can do the same.Writing will help bring you to an understanding. Give it a try.

    Old age may not sound exciting.But recent findings offer good news for older people and for people worried about getting older.Researchers found that people become happier and experience less worry after they reach the age of fifty.In fact，they say by the age of eighty­five，people are happier with their life than they were when they were eighteen years old.

    The findings came from a survey of more than three hundred forty thousand adults in the United States.The Gallup Organization questioned them by telephone in 2008.At that time，the people were between the ages of eighteen and eighty­five.The researchers asked questions about emotions like happiness，sadness and worry.They also asked about mental or emotional stress.

    Arthur Stone in the Department of Psychiatry and Behavioral Science at Stony Brook University in New York led the study.His team found that levels of stress were highest among adults between the ages of twenty­two and twenty­five.The findings showed that stress levels dropped sharply after people reached their fifties.

    The study also showed that men and women have similar feeling patterns as they grow older.However，women at all ages reported more sadness，stress and worry than men.

    Researchers say they do not know why happiness increases as people get older.One theory is that，as people grow older，they grow more thankful for what they have and have better control of their feelings.They also spend less time thinking about bad experiences.

    Professor Stone says the emotional patterns could be linked to changes in how people see the world，or maybe even changes in brain chemistry.

    The researchers also considered possible influences like having young children，being unemployed or being single.But they found that influences like these did not affect the levels of happiness and well­being related to age.

    Growing ups I always envied my friends who lived in one town in their whole lives. Coming from a military family makes this impossible. My brothers and I soon found that if we didn't like a place we lived in, we'd soon be moving to a new place. Through all the ups and downs, I now realize that' everything I've done, seen, and learned has made me into the person I am today.

    The field day was the best day ever created. Being good at sports which I had done together with parents seemed to help me find my position at a new school. Despite the hot weather in San Antonio, Texas, I had to take outdoor activities. Sometimes we •took the family mountain biking after school. My brothers and I were arranged to join in the swim team and practice yoga. These are the things I remember about my childhood. Now I thank my parents for teaching me these vital principles, which I will have with me the rest of my life.

I was always the shy girl and afraid to be myself. This didn't bother me until I reached junior high school, when some girls judged me by what I wore, who I talked to and how skinny I was. I felt like I'd never done anything wrong to deserve such criticism. It was not until last year that I realized that I had to stay different from them and live my life according to my principles. I decided to be my own person. I never thought that being nice could cause me to be disliked. Anyway, I began hanging out with girls who had a lot in common with me like preferring outdoor sports. They were accepting and non-judgmental. I am now content in u knowing that I am my own person and don't let others control my life.

    A British friend told me he couldn't understand why Chinese people love eating sunflower seeds as a snack so much. “I've met a lot of older Chinese and many have a crack in their front teeth; I believe that's from cracking the seeds, ” he said.

    I had never noticed the habit, but once he mentioned it, I suddenly became more aware. I realized that whenever I'm watching TV or typing a report, I always start mindlessly cracking sunflower seeds. My friend doesn't like sunflower seeds, and, to him, it seems unnecessary to work so much just to get one small seed.

    When we were young, the whole family would usually get together for Chinese New Year. Then, we all lived close to one another, usually in a small city, and sometimes even neighbors would go door-to-door on Chinese New Year's Eve to check out what every household was making.

    I remember my parents would be in the kitchen cooking. Out in the living room , a large table would already be laid out, complete with fancy tablecloth, ready-made dumpling fillings, and dishes full of candy, fruits and sunflower seeds. Some of the dishes were to be offered to our ancestors later, while others were for neighbors and children to eat before the evening feast. I must have learned how to crack sunflower seeds back then.

    I don't think it's right to criticize one's choice in food or eating habits, no matter how strange they may seem.

    It's not only in China. When I went abroad, I found people had all sorts of strange habits when it came to food. In Denmark, they put salted red fish on bread and eat it for dinner, no matter how much it ruins your breath. They think it's a delicacy, and it's connected to their culture. I think it's a wonderful tradition.

    There is a lake near a forest in Sweden. The water in lake is very clear and everything is quiet and still. On the far side of the water is some farmlands and further away, across the fields, is an old church built on a hill. It has just stopped raining. The brook flowing into the lake is full and there is still some half-melted snow from last winter on the ground.

    The reason the water is so clear and everything is so quiet and still, is that most of the plant and animal life in and around the lake is died. There are no birds because all the fish and insects, which the birds need for food, have disappeared. Many trees in the forest are losing their leaves and bark, and are sick and dying. Others were blown down by the high winds of last winter. A farmer is working in a field planting something, but unless he plants a stronger kind of seed this year, the crop will be between 25 to 40 percent lower than a few years ago. The stones of the old church tower are turning to power and unless the tower is repaired soon, it will fall down.

    The smoke coming out of factories and poisonous gases from cars and trucks causes all the death and destruction in this place. And yet this silent lake is hundreds of kilometers away from the nearest factory and highways.

    Christmas is a time for eating great food, giving and receiving presents, and most importantly spending time with your family watching some classic Christmas movies.

The Grinch (2000)

    This is a Christmas must-watch and one of Jim Carrey's best performances. It was also originally a nursery tale book written by Dr Seuss. It's the story of a green monster who wants to ruin Christmas but who in the end discovers the power of love and generosity. I promise it's a great film with plenty of laughs along the way.

    Love Actually (2003)

    While this is not a personal favourite of mine, people in the UK absolutely love this film. It has many featuring actors and actresses. It might be a little difficult to follow as there are complex plots, so I recommend watching a translated version or enabling subtitles (字幕) in your native language. However, the heart-warming elements of the film make it worth watching.

    Home Alone (1990)

    This amusing masterwork is one of my favourite films of all time. It tells the story of a boy, Kevin, who is left alone in his house when his large family forgets to take him on vacation with them. While the families are away, burglars try to rob the house and Kevin must protect his home by setting traps. The trips, falls and traps will have you laughing out loud as you watch a 10-year-old boy beat two grown men.

    Miracle on 34th Street (1994)

    You can't have Christmas in an English-speaking country without watching this movie. It's not funny like Home Alone or The Grinch, but it is incredibly touching. It's about a man who claims to be Santa, but nobody believes him except a lawyer and a little girl. The story-line may seem a little childish but you can enjoy it at any age.
