Analysis of test questions: Education is both a citizen's right and a citizen's obligation. Xiao Li only realized that education was his right, but neglected that education was his obligation. He doesn't know that rights and obligations are unified. Any citizen enjoys the rights stipulated by the Constitution and laws, and at the same time must fulfill the obligations stipulated by the Constitution and laws. There is no right without obligation, and there is no obligation without right. Therefore, what fits the meaning of the question is ① ③. ② It is a misunderstanding of the stem. This statement itself is wrong.

Comments: What is confusing about this knowledge point is that education is not only a right, but also an obligation. For example, Xiao Gang thought learning was boring, so he stopped going to school. The teacher goes to his home to work. He said, education is my right. Whether I go to school or not is none of your business. Please explain to him what you have learned.
