In front of Instructor Kan was a long bridge about three meters long and one foot wide. The long bridge is about 0.5 meters above the ground, and 10 meters to the east of the long bridge is a two-meter-high wooden plank wall. Instructor Kan did not demonstrate, but first explained: "When crossing the bridge, you should look ahead, not at the bridge." After crossing the bridge, you should sprint to the side of the plank wall as fast as possible, and jump quickly at a distance of 0.5 meters from the wall. Grab the side of the wooden wall with both arms and force upwards, raise your body to the left, roll over the wooden wall, and easily land. Let's take a look at the demonstration. ”

The students listened attentively to Instructor Kan's explanation, carefully watched Instructor Kan run, cross the bridge, sprint, jump, turn over the wall, and finally land smoothly with both feet. Seeing Instructor Kan's skillful movements, everyone secretly admired in their hearts, and at the same time worried about whether they would be able to cross the bridge and climb over the wooden wall when they were practicing. Instructor Kan finished the demonstration and returned to the front of the queue. He looked at everyone with encouraging eyes and said, "Which student would like to be the first to practice?" ”

The classmates present, you look at me, I look at you, no one has a base in their hearts, and they don't dare to try rashly. Just when everyone was hesitating, I heard someone in the male queue say, "Report to the instructor, I'll try." "I don't have to turn around to look, I can confirm that this person is Shen Zhe, the deputy squad leader, just by his voice. Instructor Kan said, "Shen Zhe is out of the ranks. Shen Zhe shouted: "Yes." "Ran to the west end of the single-plank bridge in front of the queue and stood still. Instructor Kan said, "Are you ready?" Shen Zhe said, "Ready." As soon as Instructor Kan whistled, Shen Zhe quickly ran towards the wooden bridge. The three-meter wooden bridge, Shen Zhe crossed it in a few steps, without any suspense. Run and sprint, take off, raise your hands, grab the wooden wall, lift your arms up, raise your body to the left, turn over the wall, and stand still. No omissions were found in a few steps, and the two training subjects were successfully completed.

Instructor Kan said: "The action is very good, but it is a little sluggish when climbing over the wall, this is because the speed of the sprint is not enough, and the jump is too early, so pay attention to correcting the action when you practice next time." Shen Zhe said, "Yes, thank you, instructor." Instructor Kan said, "Please return to the team." Shen Zhe turned around and ran back into the queue.

Instructor Kan said to the students again: "Who else is willing to try, is there any girl who takes the initiative to practice." At this time, I heard someone in the female queue shouting: "Report to the instructor, I am willing to try." Everyone turned their heads to see that the person reporting was Shen Haiyan, who was not too tall in our class. Instructor Kan said, "Please ask this girl to come out of the ranks." Shen Haiyan said: "Report to the instructor, my name is Shen Haiyan." Instructor Kan immediately corrected and said, "Please ask Shen Haiyan to come out of the ranks." Shen Haiyan said, "Yes." He put his arms on his arms and ran out of the queue to the front of the wooden bridge.

Shen Haiyan, 1.63 meters tall. The facial features are upright, the face is a little white and red, the figure is neither fat nor thin, and the appearance is also beautiful. It's just that today I was wearing a training uniform, green rubber shoes, and a training hat on my head, and my clothes looked a little fat and a little unfavorable. Instructor Kan saw that Shen Haiyan was ready, and as soon as he whistled, Shen Haiyan ran onto the bridge. When he ran to the middle of the bridge, he shook his body and almost fell off the wooden bridge. Instructor Yan shouted from the side: "Look ahead." The classmates all sweated for Shen Haiyan.

After adjusting her posture, Shen Haiyan still ran over the single-plank bridge without danger. Ten meters sprint, jump to the side of the wooden wall, grab the wall with both hands, use both arms, lean to the left, step over the wall of the wooden wall with the right elbow, the body follows the inertia, flips over the wall, moves two steps on the ground with both feet, and finally stands still. Instructor Yan shouted: "Good job, whether it is a male classmate or a female classmate, everyone must learn from Shen Haiyan." Instructor Kan said: "When crossing the bridge, pay attention to the eyes ahead, and when turning over the wall, you should pay attention to the hands to spread quickly, and you can't drag mud and water, and return to the team." Shen Haiyan shouted: "Yes." "Run back into the queue.

Instructor Kan said, "Let's practice in groups, the girls practice here, and the boys practice on the field behind you." Please pay attention to your own safety when practicing in groups, do you remember? The classmates shouted, "Remember." ”

Instructor Kan shouted: "All the girls listen to my command and take two steps forward." The girls took two steps forward. Instructor Kan said, "Please ask Huo Caixia to come out of the ranks." Huo Caixia said: "Yes." "The voice is not high, and the run comes to the front of the queue. The girls began to train on a person-by-person basis.

Instructor Yan shouted, "All the boys listen to my command and turn back." 121, 121, standing. "Everyone came to the south side of the wooden bridge and the wooden wall and stood still. We found that Director Liu was also in our queue. Instructor Yan said, "Next, please ask Ma Wangcai to come out of the ranks." Ma Wangcai, the tallest and thinnest man in the class, shouted: "Yes." "Ran out of the queue and came to the bridge. After hearing Instructor Yan's whistle, he quickly started running. Ma Wangcai, who was already very high, crossed the bridge in three or two shakes on the bridge. Jiang Zhu said: "Don't blow the wind, blow away this straw." Director Liu glanced at Jiang Zhu and said, "Don't speak, watch people's movements carefully." Jiang Zhu stuck out his tongue, grimaced, and stopped talking.

Ma Wangcai, who is tall, can get to the wall without much trouble, but because the speed is not enough, he didn't climb the wooden wall in front of the wall, so he had to regretfully return to the queue. The second place, Shen Zhe, once again followed the run, crossed the bridge, sprinted, jumped, climbed over the wall, and landed. Instructor Yan shouted, "It's been a success. "Third place Li Xiaogang, fourth place, Di Tengmei, fifth place Jiang Dajun...... The male classmates all practiced for the first time in turn, and Chen Zhen and I were left. I'm a little nervous, I don't know if I'll be able to pass this time.
