Analysis of test questions: This question examines the dynamic role of consciousness. An opinion is not philosophical, so it doesn't fit the meaning of the question. The stem of the question says that "turning evil into good is also a drug bait", which shows that consciousness has a regulating effect on people's physiological activities, so C is in line with the meaning of the question, and B and D are correct but not in line with the meaning of the question, so the answer should be C.

Comments: All the options in this question are correct. The key lies in the examination of the topic, the analysis and understanding of the materials and the multiple-choice questions of the materials. If candidates don't understand the materials, they don't know how to choose them, so candidates should first understand the meaning of the materials, and then choose the corresponding options according to the knowledge they have learned. The college entrance examination often tests this type of questions. This question is moderately difficult.
