PE classes have become a nightmare (噩梦) for Liu Fei, a 15-year-old student. He has to run at l  4 laps (圈) of the playground in every PE class. That’s n  1,500 meters!
Liu is p  for the PE test next spring. Many Junior 3 students have started doing so. The test is very important. It is w   40 points in the senior high school entrance examination (中考).
It usually i long-distance running, long jump, rope skipping and sit-ups (仰卧起坐).
“Now I can run 1000 meters in only 3 minutes 40 seconds, about 30 seconds f than before.” Liu said.
A PE teacher from Zhenjiang with teaching e  of 10 years, said, “Long-distance running r lots of energy and endurance (耐力), which cannot be gained in a short time.
Taking up other activities early is also n  . Teachers will teach you some skills and you need time to practice.
Training is important, but don’t forget to protect yourself. He s   that students should warm up before training. Start slowly and build up the activity a little at a time.
