2 . Parkour Around a City

There are many ways to travel within a city.    1     But no matter which way we travel, we have to follow the route the city planners laid down for us.

    2     To them, there are no designed routes. There are no walls and no stairs they jump, climb and crawl to move across, through, over and under anything they find in their path.    3    

The International Gymnastics Federation (FIG) has noticed that this activity is drawing more and more people to it—there are 100,000 people taking part in parkour (跑酷) today in the UK alone, according to The Guardian and how it is helpful for people to be much stronger: It trains coordination and balance.    4    

But parkour enthusiasts themselves don’t seem to be happy with the idea. They see parkour as “a lifestyle”.    5     Indeed, many do parkour just to escape the daily routine and experience the city in different ways. They see parkour as a way to express themselves through relaxing moves and creative routes while freeing themselves from the pressure.

It’s great that the FIG wants to develop a new sport and stay close to a new cultural form. But it would be greater if they knew that not everything in life is a competition.

3 . Running is a very popular sport. Millions of people run because they enjoy it or want to be in good physical shape. A runner does not need special skills or equipment.    1    .

Daily running improves a person's physical condition. It helps oxygen circulate (循环) through your body and makes your heart and leg muscles stronger.    2    .What's more, running helps you control your weight because when you run, you burn up the fat in your body.   

Many runners like taking part in long distance races like marathons (马拉松).     3    .They are held in many cities all over the world. For a good runner, taking part in a famous marathon is an honour of a running career.

There are no official world records in marathon races because courses are different all over the world.     4    . However, sometimes a course may be hilly with lots of ups and downs. Bad weather with a lot of wind and rain also makes it more difficult for runners to achieve good results.

    5    .Don't start to fast, or you will become tired very quickly and can't continue. This is called "hitting the wall". In most cases, runners then give up completely. On the other hand, you shouldn't start too slowly, or you won't reach the time limit you want to achieve.
