教材有时颇让高中语文教师心生尴尬:文意过分显豁的课文,教起来索然无味,“少慢差费”;因为各种原因内容过于艰深的课文,教起来力不从心,顿生敬而远之之意。我以为《空间和时间旅行》的前半部分属于前者,后半部分内容由于涉及“时间膨胀”等非经典物理学的知识而属于后一种情况 Textbooks sometimes make high school Chinese language teachers feel uncomfortable: texts that are overly visible and explicit; they are uninteresting in teaching, and they are “less than slow”; because the texts are overly arduous for various reasons, they cannot be taught, and they are far removed from the mind. . I think that the first half of “Space and Time Travel” belongs to the former, while the latter part belongs to the latter because it involves knowledge of “non-classical physics” such as “expansion of time.”
