Only when he finds the cause of the error, he himself is awakened, can we really solve the problem. Otherwise, the student is wrong today and will be wrong tomorrow. As a first-line teaching mathematics teacher, I agree with this passage. Before taking a test at the academic level, I chose the 2014 pumping test organization simulation exercises. This one
