夜晚的实验课

夜晚，实验室里弥漫着浓浓的气味和微弱的光线。这是我们每周一次的实验课，我们的老师，一位年轻的女教授，在黑板前讲解着实验的原理和步骤。

在她的指导下，我们开始了实验。我们仔细地称量着每一份试剂，小心翼翼地进行反应。虽然实验室里静悄悄的，但我们的心却在跳动着，因为我们知道，一旦有了一点偏差，整个实验都会失败。

时间一分一秒地过去，我们的实验渐渐接近了尾声。我们把最后一滴试剂滴入试管中，静静地等待着反应的结果。当试管里的液体开始变色时，我们的心情也随之变得激动起来，因为我们知道，我们的实验成功了！

夜晚的实验课虽然疲惫，却充满了成就感和满足感。在实验的过程中，我们不仅学到了知识，还锻炼了实验技能和团队合作能力。这样的实验经历将伴随着我们的整个学习生涯，成为我们成长的一部分。

Night Experimental Class

At night, the laboratory was filled with strong smell and weak light. This is our weekly experimental class, and our teacher, a young female professor, was explaining the principles and steps of the experiment in front of the blackboard.

Under her guidance, we started the experiment. We carefully measured each portion of reagent and conducted the reaction carefully. Although the laboratory was quiet, our hearts were beating because we knew that if there was any deviation, the whole experiment would fail.

Time passed by every minute, and our experiment was gradually coming to an end. We dropped the last drop of reagent into the test tube and waited quietly for the reaction result. When the liquid in the test tube began to change color, our mood became excited because we knew that our experiment was successful!

Although the night experimental class was tiring, it was full of a sense of achievement and satisfaction. In the process of the experiment, we not only learned knowledge but also developed experimental skills and teamwork ability. Such experimental experience will accompany our entire learning career and become a part of our growth.
