Score is not equal to knowledge, my head teacher always keeps telling me this, because he wants us to master all the knowledge we need to understand. I do not put his word in mind, because in my heart, score comes the first. One day, chemistry teacher taught us some knowledge and then asked us to finish a paper test. Whoever passed the text can do the experiment. I got a high mark by guessing. I was very happy, but tragedy happened. I made a small explosion by not mastering the knowledge. I was scared and finally understood the sentence, Score is not Equal to Knowledge.

　　分数并不等于知识， 班主任对我说，因为他希望我们能够掌握所有需要了解的知识。我并没有把他的话放心上，因为我觉得分数是最重要的。有一天，老师教了我们一些知识，然后就让我们考试。只要通过了考试才能去做实验。我瞎猜猜得了很高分。我很高兴，但是悲剧也就发生了。因为知识不牢固而导致了一个小爆炸。我被吓到了，也终于明白了那句话， 分数并不等于知识。
