14、康。关于这个问题，有不同的观点。一部分同学反对吃补品，因为补品会令他们增肥，那样不适合他们的健康发展。还有，如果父母给子女买补品，给他们过多的关心，会对高三学生有很大的影响。当他们没有考到父母所期待的高分时,他们会感到沮丧而且羞愧。此外，他们不相信只靠吃补品就能使他们的努力得到回报。然而，有些同学的观点与此完全不同。他们赞同这样的观点：高三学生学习紧张，容易感到疲劳，补品能令他们尽快恢复精力，所以吃补品很有利。答案：With the College Entrance Exam coming,from timeto time we hear students discuss whether Se

43、varietyof knowledge by reading extensively.As to me,I agree with the former opinion.Admittedly,we canabsorb knowledge by reading extensively,but it doesn，tfollow that we should read without discrimination.As ourtime and energy are limited,we should devote our limitedtime and energy to reading relevant and beneficial books.It，sawasteoftimetoreadirrelevantbooks.Furthermore,some books are harmful to one，s mind.If wedont read books selectively,we will be misled by harmfulbooks.祝您
