近几年高考文综试题有一个特点,即一组选择题往往都由一句或一段背景知识引导。背景知识不是可有可无的,它对选择题的解答有很强的指导性。下面举两例。例一:民主与法制对中国革命与建设至关重要。回答20～23题(2003年全国高考文综题)23.中共十三大制定的党在社会主义初级阶段? In recent years, the college entrance examination papers have a special feature, that is, a group of multiple-choice questions are often guided by one sentence or background knowledge. Background knowledge is not dispensable. It has strong guidance on the answer to multiple-choice questions. Here are two examples. Example 1: Democracy and the legal system are crucial to the Chinese revolution and construction. Answer 20 to 23 questions (2003 national college entrance examination papers) 23. What is the party’s enactment of the 13th National Congress in the initial stage of socialism?
