1.I am always interested in experiments(实验),especially chemistry ones.Experiments were fun for me until a recent accident.The accident happened when I was heating a big test tube (试管),talking to my partner while waiting for chemical changes.All of a sudden,the tube broke.Even though I jumped from my seat,the hair on my forehead was burnt (燃烧).But I had no time to be sad about my hair:the liquid (液体) in the test tube poured onto the table and caught fire.I'd never experienced anything so bad!It was scary.Then I quickly covered the fire with a damp cloth.Soon the fire was put out (扑灭)The teacher told me that the test tube broke in half because we didn't dry it properly before heating it.After a while we did the experiment again.But our hearts were still beating rapidly even after we walked out of the lab.But my bad luck didn't end there!During the following class,I felt a pain in my leg.Soon it became more and more painful and I touched the area with my finger,trying to make things better.But to my great surprise,the material of my trousers turned into powder (粉末)"Vitriol (硫酸)"!The terrible word came into my mind.I rushed out right away to wash and examine my poor leg.Luckily,it was not a serious hurt.
After changing my trousers I sat down and told myself:danger is no joke!
