由于各种原因，后进生与优等生在知识、智能、兴趣、特长、性格和个性品质等方面存在着一定的差异。他们总有一两个甚至几个方面处于班级水平线下或是最底层。又因不被人重视，经常受冷落，得不到呵护，所以，后进生与进步学生的距离常会拉得越来越大。我认为，要真正有效缩短? For a variety of reasons, there are some differences in the aspects of knowledge, intelligence, interests, specialties, personality and individual qualities among students who have graduated from high school and those who are excellent students. They always have one or two or even a few classes below the class level or the bottom. And because of not being valued, often ignored, without care, so the distance between students and progress students will get bigger and bigger. In my opinion, to really shorten effectively?
