The teacher came, see her only a hand puts rearward, a hand took a tray only, an iron plate was put inside dish, a forceps, a bottle of alcohol, a match and a handkerchief, connect Chinese book to also was not taken.
“铃铃铃……”上课了，同学们静静地等待着老师的到来。老师来了，只见她一只手放在背后，一只手只拿了一个盘子，盘子里面放了一个铁碗，一把镊子，一瓶酒精，一盒火柴和一块手帕，连语文书也没有拿。
My heart thinks: What medicine is what sell after all in teacher calabash? The teacher says: “ does an experimental —— to burn not bad handkerchief today! I listened to ” astonied! Think in the heart: How this is likely!
我心想：老师葫芦里到底卖的是什么药？老师说：“今天来做个实验——烧不坏的手帕！”我听了大吃一惊！心里想：这怎么可能呀！
The teacher takes a chair, put on the desk, put the dish of a white on the chair again. Next teacher handle handkerchief is put in dish, cap of alcohol of to turn on, enter dish in. “ can burn more exuberant more so, teacher. ” is the same as doctrine. See the teacher takes forceps only, handle handkerchief dips in even, a pungent alcohol flavour is tangy and come, “ is really unpleasant! I am holding ” nose says.
老师拿起一把椅子，放在桌上，再把一个白色的盘子放在椅子上。然后老师把手帕放在盘子里，拧开酒精瓶盖，倒入盘中。“这样会越烧越旺盛，老师。”一个同学说。只见老师拿起镊子，把手帕蘸均匀，一股刺鼻的酒精味扑鼻而来，“真难闻！”我捏着鼻子说。
Then, the teacher is taking ignition match, toward on the handkerchief a bit, lighted on handkerchief of “ Zhi ” deep and remote blue flame, I worry for the destiny of small handkerchief really. Some learns to be able to 't restrain curiosity with the composition, stood, the fellow student that takes in in front of relies on body in the future, small flame of for fear that comes here to swim to the “ on him body ” . Passed a little while, the teacher took sheet iron, buckle go up in dish.
接着，老师拿着点燃的火柴，往手帕上一点，“吱”的一声手帕上燃起了幽蓝的火苗，我真为小手帕的命运担心。有的同作文学按捺不住好奇心，站了起来，坐在前排的同学把身体往后靠，生怕小火苗到自己身上“到此一游”。过了一会儿，老师把铁碗拿了起来，倒扣在盘子上。
“ witnessed miraculous time to arrive! Mr. ” took sheet iron, take safe and sound handkerchief next, appeared a black smoke. “ ! Very magical! Everybody says ” agape. Is “ how to return a responsibility then? Mr. ” asks, immediately, the blast in the classroom opened boiler. A classmate says: “ is fireproof thing was included on the handkerchief! ”“ is incorrect, incorrect, pron any thing was not included on the handkerchief. Mr. ” says. Another classmate stands up say: Because “ has moisture content in alcohol. ” one's voice in speech just fell, the teacher is laughing at an alcohol to take us to look, writing on brand: 75% alcohol, 25% water. It is fire cooks alcohol first so, alcohol was burned heat water again, water burned what burn a handkerchief again, just had “ to burn not bad handkerchief so. ” illustration 3
“见证奇迹的时间到了！”老师把铁碗拿了下来，然后拿起安然无恙的手帕，冒出了一缕青烟。“哇！好神奇呀！”大家目瞪口呆地说。“那是怎么回事呢？”老师问，顿时，教室里炸开了锅。一个同学说：“是手帕上包了防火的东西！”“不对，不对，手帕上没有包任何东西。”老师说。又一个同学站起来说道：“因为酒精里有水分。”话音刚落，老师就笑着把酒精拿上来给我们看，商标上写着：75%酒精，25%水。原来是火先烧酒精，酒精烧完了再烧水，水烧完了再烧手帕的，所以才有了“烧不坏的手帕。”插图三
