First, for students who are not good at physics and history, the "3+3" model has 20 combinations for students to choose from, and Zhejiang Province has more, while the "3+ 1+2" model has 12 combinations for students to choose from, because physics or history is a compulsory subject, which is obviously unfair to students who are not good at these two subjects, because in "3+3"
On the other hand, the second kind of students are very good students in physics and history. He could have chosen to combine the two subjects, but now he has to give up. In fact, the history discipline focuses on cultivating students' historical interpretation, historical evidence, feelings of home and country, and the ability to analyze problems from multiple angles and innovative thinking. These are just a powerful supplement to studying physics, which is helpful to cultivate science and engineering talents with feelings and innovative thinking. Therefore, the role of history in physics is more important than geography and politics, even more important than biology and chemistry. For students who are good at physics, there are many students who are good at history or physics. It is not difficult to learn history well, but the mode of "3+ 1+2" blocks the way for students.
