高中生物教材中总是有很多的语句隐含了前提条件,教师在教学过程中如果不将它们挖掘出来,不注重强调和补充,学生往往会对该知识产生严重的片面性理解。 There are always many sentences in the high school biology textbooks that imply the preconditions. If teachers do not dig them out during the teaching process, they do not pay attention to emphasis and supplement, and students often have a serious one-sided understanding of the knowledge.
