A

Test question analysis: Any organism is itself but not itself at every moment, and is always in constant change. Explain that things are the unity of absolute motion and relative stillness. The flowers are similar every year, but the people are different every year. Just like sitting on the ground and traveling eighty thousand miles a day, surveying the sky and looking at a thousand rivers in the distance. It is the unity of absolute motion and relative stillness. Therefore, choose option A for this question. Thousands of sails pass by the side of the sunken boat, and thousands of trees spring in front of the diseased trees. The underlying philosophy is that new things triumph over old things. The swirling hills and mountains are always quiet, and the rivers are racing but not flowing. The philosophy behind them is movement. Items ② and ④ are correct in themselves but do not conform to the meaning of the question and should be eliminated.

Comments: This question requires students to use the unity of absolute motion and relative stillness to answer the question. It also requires students to learn to draw conclusions through the analysis of materials. This is also a convention for college entrance examination questions. This question is of moderate difficulty.
