Rope skipping is a sport suitable for people of all age. People skip rope for fun and exercise. Every student can learn to skip. You can skip alone or with my classmates. If you skip alone, you just need short rope about double the length of your high. You can't turn to the rope too fast so that you can skip safe. It might help if you can sing a rhyme while skips. When you skip rope, your heart beats fast than usual and your body is stressed. Therefore, stop for a rest after you injure yourself. So, pick up a rope, finding a silly rhyme and start skipping.

I love running. I started running in 2016, look forward to building up my body. Every weekday I stay actively by running on the track with other student. On weekends, in company by my father, I typically get out to explore the neighborhood in that I live. If the weather is bad, I usually take my advantage of the treadmill(跑步机)at home．The other day I go for a 22-km run. I was very exciting，“Wow, I've been running such long distance，”I will plan to keep increasing the distance over the next few weeks, but I'm sure I will make it.
