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.

    Do you know oil platforms (石油钻井平台)? They pump out (大量生产) oil from under the ocean (海洋). There can be over 100 people living and working on an oil platform. {#blank#}1{#/blank#}

    The people on oil platforms do a number of different jobs. There are engineers, cooks, doctors, cleaners, etc. But the roughnecks (石油钻井工人) have the hardest job. {#blank#}2{#/blank#}It's hard, dangerous work.

    There are no weekends on oil platforms. Usually, people work every day for two weeks. Then they go back to land to have two or three weeks off from work.

    The people on oil platforms can play games and watch TV when they don't work or sleep. {#blank#}3{#/blank#}There's not much space, and you can't just go for a walk.

    Oil platforms are dangerous places. Everyone needs to work carefully.{#blank#}4{#/blank#}An accident (事故)on the platform Deepwater Horizon in 2010 killed eleven people and a lot of oil went into the ocean.

    After that accident, some people said that oil platforms were just too dangerous.{#blank#}5{#/blank#}So we still need people to work in these difficult, dangerous places.

    There are different outdoor activities for different seasons. In spring we can fly kites .In summer, we can go swimming or sailing. In autumn, it is a good idea to camp or hike. In winter, we can go to ski or skate. They bring us a lot of fun .They make us strong and fit, too. So it is important for people of all ages to take part in some outdoor activities at the right time.

    There are many group activities ,like football and basketball .The members work together for the same goal（目标）. So group activities need team spirit(团队精神). It is very useful for a person to have team spirit. It is good for us in life and work.

    Old people like walking and jogging .These outdoor activities don't need much strength（气力）. Young people like exciting activities ,like diving（潜水）, skiing and horse riding. Children like fun activities like flying kites.

    Some outdoor activities are dangerous, like climbing rocks. So we must be careful when we take part in them.

    Bikes and cars are two important (重要的) things. Many Chinese people have cars now, but most Chinese people still like to ride bikes. Do you know why?

    We all know that the bike can't go quickly, but it's easy for people to buy and ride it. As for the car, it needs too much money.

    Most Americans live far from the center of cities or their working places. So they need cars to go shopping or go to work every day. Most Chinese people live near their working places, so they don't need cars to go to work. And it's good for the environment (环境) if people stop driving. That's why it is “No­Car Day” on September 22nd every year.

    For me, I like to go to school by bike. It is easy and healthy.

    American schools begin in September after a long summer holiday. There are two terms in a school year; the first term is from September to January, and the second is from February to June. Most American children begin to go to school when they are five years old. Most children are seventeen or eighteen years old when they finish high school.

    High school students take only five or six subjects each term, they usually go to the same classes every day, and they have homework for every class. After class, they do a lot of interesting things.

    After high school, many students go to colleges. They usually have to pay a lot of money. So many college students work after class to get money for their studies.
