2. How important is the high school proficiency test? Different provinces have different subjects and contents.
Generally speaking, high school compulsory modules are the main ones, and the presentation of grades tends to be hierarchical. Judging from the examination contents of the ordinary high school level examination in each province, the examination subjects and contents in each province are different. The first category is the level examination of various scientific professions, representing provinces and cities such as Anhui, Tianjin, Shandong and Heilongjiang.
For example, the academic level examination for senior high school students in Anhui Province includes six subjects: Chinese, mathematics, foreign language (including listening), humanities and social foundation (ideological and political, history, geography), science foundation (physics, chemistry, biology), and technical literacy (information technology and general technology), all of which test the learning content stipulated in the compulsory credits of related disciplines in senior high school. The integration of general technology into the test discipline and the computer test of information technology are the highlights of the academic level test for ordinary high school students in Anhui Province.
Tianjin ordinary high school academic level examination is divided into municipal examination and district and county examination. Municipal examinations include Chinese, English, mathematics, ideological and political, history, geography, physics, chemistry, biology (including content, chemistry, biology experiment and English listening test; Open-book examination is implemented in ideological and political disciplines).
Information technology and general technology are set up in district and county examinations. This paper mainly investigates the contents of compulsory modules, among which elective modules are added to Chinese and mathematics subjects.
The examination subjects organized by Heilongjiang Province are ideological politics, history, geography, physics, chemistry, biology, information technology and general technology. The school organizes examinations in Chinese (Korean or Mongolian), English (Russian or Japanese), mathematics, physics, chemistry, biological experimental operation and comprehensive practical activities. It is a compulsory course content stipulated by the examination course standard.
The second category is the academic proficiency test of some subjects, and the representative provinces are Hainan and Jiangsu. The basic examination subjects in Hainan Province include politics, history, geography, physics, chemistry, biology, information technology and general technology, and the "reverse examination" is implemented.
Candidates who intend to enter the college entrance examination for literature, history and art must take the basic examinations of physics, chemistry, biology, information technology and general technology; Candidates who intend to apply for science, engineering and physical education must take the basic examinations of ideological and political, history, geography, information technology and general technology. The examination scope of the basic examination includes compulsory modules in all subjects and elective modules required for graduation compulsory credits.
The subjects of the academic level examination in Jiangsu Province include politics, history, geography, physics, chemistry, biology and technology (including information technology and general technology), which are divided into compulsory subjects and elective subjects, including 5 compulsory subjects and 2 elective subjects. Elective subjects are history, physics 1, politics, geography, chemistry, biology 1.
Of the seven academic proficiency test subjects, except for two optional subjects, the other five are compulsory subjects. Compulsory subjects only test the compulsory content, and elective subjects include compulsory and elective modules.
Whether it is the academic proficiency test of all subjects or the academic proficiency test of some subjects, except that Hainan Province converts the score into 10%, which is included in the total score of the college entrance examination, all provinces and cities basically adopt the A, B, C and D grading system to present candidates' scores.

Analysis: In the process of spring ejecting the projectile, the elastic force does work on the projectile. According to the relationship between elastic work and elastic potential energy change, it is known that the elastic potential energy of the spring will decrease and the kinetic energy of the projectile will eventually increase regardless of the mass of the projectile and the amount of elastic work.

Analysis: The velocity of particle P passing through a semi-circular arc for the first time is greater than that for the second time, so the pressure and friction force passing through the circular arc for the first time are greater than that for the second time, and the object does work on the friction force for the first time is greater than that for the second time. According to the kinetic energy theorem, there are
