今年我升初三,多了一个陌生的科目,那就是——化学!刚开始接触化学方程式的时候,我真是欲哭无泪啊!很明显的沉淀或气体,我却时常忘记给它们标上一个向下或者向上的箭头。这可让我出了大糗。“这节课我们来写化学方程式!嗯,现在请3个同学到黑板上来写。”一次课堂上,化学老师周永华说道。我被点名了,心怀忐忑地走上讲台,拿起笔,准备答题。 This year, I started my third year with an unfamiliar subject, that is - Chemistry! When I first came into contact with the chemical equation, I really did not cry! Obviously precipitation or gas, but I often forget to mark them A downward or upward arrow. This will get me out of the big room. “This class we write chemical equations! Well, now 3 students to the blackboard to write. ” In a class, chemistry teacher Zhou Yonghua said. I was named, heartfully embarked on the podium, picked up the pen, ready to answer.
