Our lifestyles today are very busy. We have family, school, sports, entertainment and social activities to fit into a time that seems never enough. We need to be healthy to meet the demands of daily life. But what does it mean to have a healthy lifestyle?

To have a healthy lifestyle, we need to:

◆ eat different kinds of healthy food most of the time

◆ do exercise often

◆ have time to relax

◆ get enough sleep to give our bodies time to grow healthy and strong

Read about a normal day in the lives of two children.

    No matter which kind of lifestyle you agree on, just remember it's important to balance all aspects of life.

    It was the men's figure skating final of the Winter Olympics when I was 16.I lay on our living room floor excitedly watching the battle between the Brains: American Brain Boitano facing Brian Orser in Canada. Both of them had been world champions. Both of them deserved to win. As a Northern Californian, I was for my fellow countryman. He also grew up in Northern California. We'd skated on the same ice. Brain performed successfully. The champion! I jumped in the air when his score went up.

    But what happened next is what I'll never forget. Brain sat in front of the camera, surrounded by a group of journalists. Brain was talking about his career and his medal, talking to the whole world. A terrible sinking feeling went through me. I could never be in the Olympics,

    I thought, I loved skating because I could express myself with my jumps and dances better than words.

    What if journalists asked me questions like they asked Brain? I'd freeze up like the ice beneath my skates! And yet, there was so much I would love to say, about my family and all the support they'd given me and about following my dream of being a skating champion.

    I worked very hard the next few years — on the ice and especially off. After journalists talked to me and although my heart pounded every time I spoke to them, I got to know them. And they got to know me. Slowly I learned that the best approach was simply to be myself, to be honest and gracious and do my best, just like on the ice, to answer their questions.

    So when my big moment came four years after Brain's, I was ready. Remember: when you do the thing you fear most, you put an end to fear.

                                                                                 Is There Life on Earth

    There was great excitement on the planet of Venus this week. For the first time Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since.

    The satellite was directed into an area known as Manhattan(named after the great Venusian astronomer Prof. Manhattan, who first discovered it with his telescope 20,000 light years ago). Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information as to the feasibility(可行性)of a manned flying saucer(飞碟)landing on Earth. A press conference was held at the Venus Institute of Technology.

    “We have come to the conclusion, based on last week's satellite landing,” Pro. Zog said, “that there is no life on the Earth.”

    “How do you know this?” the science reporter of the Venus Evening Star asked.

    “For on thing, Earth's surface in the area of Manhattan is composed of solid concrete and nothing can grow there. For another, the atmosphere is filled with carbon monoxide and other deadly gases and nobody could possibly breathe this air and survive.”

    “What does this mean as far as our flying saucer program is concerned?”

    “We shall have to take our own oxygen with us, which means heavier flying saucer than we originally planned.”

    “Are there any other risks that you discovered in your studies?”

    “Take a look at his photo. You see this dark black cloud floating over the surface of Earth?” We call this the Consolidated Edison Belt. We don't know what it is made of, but it could give us a lot of trouble and we shall have to make further tests before we send a Venus Being there.”

    “If what you say is true, won't this set back the flying saucer program several years?”

    “Yes, but we shall proceed as soon as the Grubstart gives us the added funds.”

    “Pro. Zog, why are we spending billions and billions of zilches to land a flying saucer on Earth when there is no life there?

    “Because if we Venusians can learn to breathe in an Earth atmosphere, then. We can live anywhere.”

    My daughter Kelly is a cautious person. She needs to warm up to situations' and is hesitant to try new things. When with close friends, she becomes a leader who laughs loudly and chants, “Girls rule, boys drool.” But when that comfort zone is not around her, she is shy and nervous.

    This has been challenging for me at times. “Shy” is not a word that I think has ever been used to describe me. But this has been a year of firsts for my girl that has filled her with a new sense of confidence. This year she moved to lap lane in swimming where she was preparing for a swim team. This year she learned to ride a bike without training wheels. And this year she completed her first kids' triathlon (三项全能).

    On Saturday, with a thunderstorm coming soon and my son's birthday party later in the day, we all went out in the dark of the morning for Kelly to participate in her first triathlon. We practiced transitions from swim to bike to run with her, we got all the equipment she'd need, and we kept talking about the race. But as we waited the two hours for the older kids to finish before her turn, she held my leg a little harder and told me she loved me a few too many times. She was nervous but trying to keep it together.

    And then it was her turn. From the second she jumped into the water, my heart soared. My daughter transformed into the most confident human being I had ever seen. She dominated that swim, crushed that bike ride and ran to the finish with the biggest smile on her face.

    I can honestly say that I never felt so proud of someone in my entire life. It wasn't because she did a sport or anything like that. It was because she was afraid of something and conquered that fear with confidence and a fire I hadn't seen before.

    All day I would find myself just looking over at her and smiling. She might be wearing the finalist medal but I felt like I won that day. I won the chance to see my girl shine.

Shine on, sweet baby.

    I grew up in New York my whole life. I studied in a perfect college that happened only to be an hour away from home. Then, about three weeks before the spring term was over, my parents told me we were moving to Arizona that summer. They asked me if I was going to transfer (转学) to another college. I said no. I was not going to change everything in my life at one time and I loved my college and all the amazing things I was doing there. It was my second home; I would not leave everything I knew at the same time since that was asking for trouble.

    I never imagined it would be this hard but, at the same time, the best thing that could have happened to me.

    When out in Arizona, life was hard. I didn't know anyone other than my family and friends. I couldn't bear the extreme heat. But it has helped me so much. I have started working on my writing. I also have time to work out in the gym. It has helped me realize that no matter where you are or who you know you can always find something that you enjoy.

    When back at school in New York, it was hard as well. Living close to home was my security blanket. If something was wrong I could get in my car and drive home and see my family. After my family moved to another city, I lacked security and was always controlled by anxiety. However, it helped me learn independence and forced me to be brave.

    I' m so thankful that I didn't transfer to a different school, which has given me the opportunity to go back and see best friends in my hometown. A year ago, I officially left my hometown for good. It has helped me grow and I am so thankful that I have had this experience. Now, when I graduate from college, I can go anywhere I want. I am no longer afraid to go out on my own into the world. The world is full of opportunities and pleasure and I can't wait to see where I will be next.

    Who is smarter? A human being or artificial intelligence?

The question swept the world last week when a Google-developed program called AlphaGo defeated the world top player, South Korean Lee Se-dol, 4-1.

    So, what comes next?

    Some people have been arguing that artificial intelligence, or AI in short, will be a bad thing for humans. In an interview with the BBC in 2014, UK scientist Stephen Hawking warned that “The development of full artificial intelligence could mean the end of the human race.”

    So are we really about to live in the world shown in the Terminator movies?

    “Not quite,” answered The Economist. After all, it's not hard to get a computer program to remember and produce facts. What is hard is getting computers to use their knowledge in everyday situations.

    “We think that, for the human being, things like sight and balance(视觉平衡), are natural and ordinary in our life.” Thomas Edison, founder of Motion Figures, a company that is bringing AI to boys, told the newspaper. “But for a robot, to walk up and down just like human beings requires various decisions to be made every second, and it's really difficult to do.”

    As The Economist put it, “We have a long way to go before AI can truly begin to be similar to the human brain, even though the technology can be great.”

    Meanwhile, John Mark off of The New York Times said that researchers should build artificial intelligence to make people more effective.

    “Our fate is in our own hands,” he wrote. “Since technology depends on the values of its creators, we can make human choices that use technology to improve the world.”
