新学年开始,又迎来了一批高一新生。为了使他们迈好初中到高中的第一步,顺利地学好高中化学。在讲授高中新知识之前,我们安排了几课时来复习初中内容,这实质上是初步完成初、高中知识的过渡复习,让新生扎实迈 At the beginning of the new school year, we welcomed a group of freshmen. In order for them to take the first step from junior high school to high school, they can successfully learn high school chemistry. Before teaching high school new knowledge, we arranged several lessons to review the content of junior high school. This is essentially a preliminary review of the transition from early to high school knowledge, so that new students will take a solid step forward.
