今天,老师带了许多东西走进教室,神秘地对我们说:“同学们,今天我们来做一个实验——烧纸船。”大家听了,都觉得很奇怪:“纸船有什么好烧的,烧久了不就变成灰了?”大家都用好奇的目光看着老师。老师先请程涛当助手,又拿出早就准备好的一只纸船、一杯水、一盏酒精灯和一铁架台。 Today, the teacher brought many things into the classroom and said mysteriously to us: “My classmates, today we are going to do an experiment - a paper-burning boat.” Everyone listened and felt very strange: “What a good burning paper boat , Burn a long time not become gray? ”Everyone looked curious eyes on the teacher. The teacher first invited Cheng Tao as an assistant, but also took out a paper boat that had been prepared for a long time, a glass of water, an alcohol lamp and an iron stand.
