The second grade students read pictures and wrote words on the playground as follows:

In physical education class, the students were doing exercises on the playground. Some are playing tug of war, some are high jumping, playing basketball, and some are shooting rubber balls. The most interesting thing is the tug of war.

The referee whistled and waved a small flag. Some students held the rope tightly, standing straight with their heels staring at the ground. The person at the back bowed and lowered the rope. Searching hard on the shoulders, at the end of the competition, this group won first place.

Extended information:

1. The playground is a venue used for physical exercise. It usually refers to a dedicated venue for sports and teaching activities in schools.

Physical education class is the basic organizational form of physical education. It mainly enables students to master basic knowledge of sports and health care, basic techniques and skills, realizes students' ideological and moral education, and improves sports technology level.

2. Schools should organize and implement physical education teaching activities in accordance with the regulations of the education administrative department. Physical education classes must be offered in all grades of ordinary primary and secondary schools, agricultural middle schools, vocational middle schools, secondary vocational schools and in the first and second grades of ordinary colleges and universities. Ordinary colleges and universities offer physical education elective courses to students in grade three or above.

3. According to the "Experimental Plan for Compulsory Education Curriculum" issued by the Ministry of Education in 2001, Chinese, mathematics, physical education and health courses are all national courses offered at the compulsory education stage.

4. Since the end of the 18th century and the beginning of the 19th century, when European countries such as Denmark and Germany first made physical education a required course in primary and secondary schools, most countries have included physical education in primary and secondary schools. In the U.S. education law, there are no specific provisions stipulating the establishment of physical education courses in primary and secondary schools. However, in about 1/2 of the states in the country, physical education courses are compulsory, and most of the remaining schools also take physical education courses as electives.

5. In China, physical education is one of the required courses in primary and secondary schools. It is taught by physical education teachers in an organized and planned manner based on the class teaching system based on the physical education syllabus promulgated by the Ministry of Education, focusing on practical classes. It is the basic organizational form of sports in primary and secondary schools.

6. The structure of a lesson refers to the several parts that make up a lesson, the order of teaching materials in each part, organizational teaching methods and time allocation, etc. In physical education classes, students are mainly engaged in various physical activities. The organism has to bear certain physiological loads and also undergo certain intellectual activities.

7. Therefore, the structure of physical education classes must not only follow the general laws of human cognitive activities, but also follow the laws of physiological function activities. The laws of physiological function activities are generally divided into three stages: rising - stable - declining, which reflects the general trend of changes in the human body's working ability.
