Any time of the day you can devote to exercising is a good time for getting active, but if you want to make a healthy fitness plan, it may be helpful to keep several points in mind and find out the best time to exercise.

    First, try to know what kind of person you are. Especially, are you an early bird who always wakes up early in the morning, or a night owl(猫头鹰)who almost never goes to bed before midnight? Once you are generally aware of what your sleep characteristics are, you will have a better understanding of when your body needs exercise, either early in the morning, sometime during the day, or later on in the evening.

    Second, consider your daily plan. When do you seem to be most busy, and when do you plan your most important tasks? Try to fit in your exercise before or at least around these events if possible, so that you can keep exercising and your life won't be influenced as well.

    Third, think about when you feel you have the most energy. For most people, that time is usually in the morning after a good night's rest, or after a long day of work. After a busy or much stressful day, exercising can reduce your working stress from hard work.

    Lastly, find out the place you plan to do exercise. Your house provides exercise at any time if you own fitness equipment(设备)，but if there is a gym(健身房)down the street or along the way home from work, it will make it more suitable for you to exercise.

    More importantly, you need to make a plan and try sticking to it for one week. If you do so and can get through the exercise without being pulled in another direction, make it a habit. And once you have set up your fitness plan, don't make any great changes to it unless your doctor allows you to.

    There was once a King and he wanted to find out who could paint the best picture of peace. And he would offer a prize to the artist. Many artists tried. The King looked at all the pictures but there were only two he really liked and he had to choose between them.

    One picture was of a calm(平静的) lake. The lake was a perfect mirror for peaceful mountains all around it. Overhead was a blue sky with white soft clouds. Everyone thought that was a perfect picture of peace.

    The other picture had mountains too. But these were rugged(崎岖的） and bare（无遮蔽的）.Above was an angry sky. And it was raining and lightening. Down the side of the mountain, a waterfall fell quickly. This did not look peaceful at all.

    But when the King looked carefully, he saw behind the waterfall a bush(矮树丛)growing in a crack（裂缝） in the rock． In the bush a mother bird had built her nest（巢，窝）, There, she sat on her nest… in perfect peace.

    Which picture do you think won the prize?

    The King chose the second picture."Because, "said the King, "peace does not mean to be in a place where there is no noise, trouble, or hard work. Peace means to be in the middle of all those things and still be calm in your heart. That is the real meaning of peace.

    Have you ever seen Korean writing before? In many people's eyes it looks lovely but difficult. Do you know the history of this special alphabet?

    Long ago, Korean people didn't have its own alphabet. At that time, Koreans used Chinese characters. Because Chinese is hard to learn, only rich people had the money and time to find teachers to teach them.

    One of their kings was called Sejong. He decided to invent a Korean alphabet.

    He thought hard. One day, on October 9,1446, he looked at a window frame and shouted: "I know what our alphabet should be!" He got the idea from the frame and invented characters of all the same size, like they were put in a frame.

    Hunmin Chongum, the earliest Korean alphabet was born.

    King Sejong said," Chinese characters can't express Korean meanings. These letters are very easy to learn. It is my hope that they can help all people learn to read."
