中学生时期是人生的一个关键时期,一个人的思想逐渐发展、定型,知识不断丰富,身体发育成长.要努力全面发展.不要偏废. 在长知识方面,我想谈谈怎样学好数理化.有的同学觉得数理化很难,我想主要是由于学习方法不好.要学好数理化,首先,上课要专心.特别是在学期开始时,一定要弄懂新的课程内 The period of middle school students is a crucial period of life. A person’s thinking gradually develops, stereotypes, knowledge is constantly enriched, and the body grows and develops. It is necessary to strive for all-round development. Do not neglect. In terms of long knowledge, I want to talk about how to learn mathematics and physics. The students think that mathematics and chemistry are very difficult. I think the main reason is that the learning methods are not good. To learn maths and physics and chemistry, first of all, class should be attentive. Especially at the beginning of the semester, we must understand the new curriculum.
