近年的中考试题大多以生产生活中发生的重大事件为情境考查化学知识,强调知识的迁移与运用。展望2007年中考,这种命题模式定会继续采用。现将生产生活中发生的与化学知识有关的重大事件归纳整理,并设计了相应习题,供参考。 In recent years, most of the medium-term examination questions are based on the major events that occurred in production and life as the context to examine chemical knowledge, emphasizing the transfer and application of knowledge. Looking into the 2007 midterm exam, this propositional model will continue to be adopted. The major events related to chemical knowledge that have occurred in production and life are summarized and organized, and corresponding exercises are designed for reference.
