Many people run for exercise. But what will you do if you are not a “born” runner or jogger (慢跑者)? You may still want a kind of exercise that's inexpensive and easy to do. Why not try walking?

Walking requires no special equipment (装备). It is a kind of exercise that almost any normal, healthy person can do. Walking is good for your health like jogging or running; it will just take longer. Jogging and running make your heart work harder than walking. They also put more stress on your legs and feet than walking does.

    The problem with walking is that most people don't take it seriously. But there's a big difference between serious walking and the walking that most of us do. Walking, like jogging, should have a steady and continuous motion (稳健而持续的动作).

If you want to get your exercise by walking, you need to have your own walking plan. After all, runners and joggers set goals for themselves. Walkers need goals, too. You also need to set a course to walk. Start by walking about 15-30 minutes a day. Increase your time and distance (距离) slowly. And try increasing your walking speed little by little.

If you prefer to jog or run, follow the same advice. Start off slowly. Spend most of the first few days just walking. Then, start walking and running on the same day. Run or jog a short distance, then walk for a while, then, run, then walk. Follow that pattern for 15-30 minutes a day. Slowly make each run longer and each walk shorter. Later on, you can increase your distance, speed and exercise time.

    On May 5^th, 2017, at Shanghai Pudong International Airport, China's first Homemade jet airliner(喷气式客机), the C919, took off successfully for the first time. It has taken about ten years for the scientists and researchers to make this Chinese dream come true. It's a pride of the whole nation. So far, more than 23 countries have already ordered 570 C919 planes from China. But we still have a long way to go before the C919 carries passengers by 2020.

    What's more, China is working on the new high-speed trains with the highest speed of 400km/h. It will be ready by 2020. Many countries, especially the ones in Central Asia, Southeast Asia, the Middle East and Eastern Europe, are planning to build high-speed rail lines or to improve their railways with the help of China.

    China has made great progress in both science and technology. And it makes a great contribution(贡献)to humans，too. All of these are changing the daily life of Chinese people，even of the people around the world.

    Nick and his friends were talking about things that can bring them luck.

    "I have a lucky red pen," said Andy. "Every time I take a test, I carry my lucky red pen."

    "I have a lucky coin," said Peter. "Every time I take a test, I carry my lucky coin."

    Nick thought for a moment, and said, "My blue socks."

    "Blue socks?" the boys were surprised and asked together.

    Nick said that every time he wore his blue socks to school before a test, he got a good mark.

    The next day Nick had a Chinese test. He was sad because he couldn't find his blue socks.

    "Mom!" shouted Nick. "Where my blue socks? I have a Chinese test today, and I need to wear them."

    "Don't be silly," Nick's mom said. "They need to be washed." "When I wear them, I get a good grade," Nick said.

    "Did you prepare for your test?" asked Mom.

    "Yes."

    Mom encouraged him,"①那就不用担心了。尽你的最大努力吧。"

    A few days later, Nick's teacher told him that he got 95 in his test. ②Nick was so excited that he couldn't wait to tell Mom that he did well in his test.

    Mom said, "It wasn't the blue socks that made you success. In fact, it was made by yourself."
