| Editor, Recently, my classmates have had a heated discussion about that we should have optional courses (选修课) in high schools. Some students were on favor of the optional courses. They say interest is the best teacher and our spare time will be colorful and meaningful. Students can not only enlarge their knowledges but also improve their abilities. However, others are against the idea, said that optional courses will take up too much time as well as energy. In addition to, some optional courses have something to do with the College Entrance Examination. They are afraid they"ll fall behind their classmates if they will take the optional courses. I"d like to take one or two of the optional courses, which, I think, will certain benefit me a lot. | 1._______ 2._______ 3._______ 4._______ 5._______ 6._______ 7._______ 8._______ 9._______ 10._______ |
