Taking a thick alcohol taste, teacher face takes the classroom that comes smilingly to clamorous. Immediately, not even a crow or sparrow can be heard in the classroom, classmates sorption nose, happen to coincide the ground searchs alcohol flavour origin. At this moment the teacher sends a word suddenly: We should do “ today an interesting experiment, the name makes burn not bad handkerchief. ”
带着一股浓浓的酒精味，老师面带微笑地来到了闹哄哄的教室。顿时，教室里鸦雀无声，同学们吸着鼻子，不约而同地寻找酒精味儿的来源。这时老师突然发话了：“今天我们要做个有趣的实验，名字叫烧不坏的手帕。”
Classmates hear this experiment name to comment in succession, my uncertainty ground thinks: How can be the handkerchief burned not bad? Proper my feel puzzled when, the teacher does not no hurry unbearably the ground takes out a neat handkerchief. Use alcohol handle handkerchief to be soaked completely first, twist dry. Then, place the handkerchief cautiously with forceps dish in, ignite with match, classmates are looked at absorbedly, for fear that misses which wonderful instant. Did not wait for everybody full marks / delay crosses a god to come, listen to “ to breathe out of ” only, handkerchief upblaze, change of flame straight upgrade, fire is burned more jump over flourishing, classmates mouth of magnify of eye of each goggle at. Finally, the teacher sees baked wheaten cake is gotten about the same, use big bowl to buckle dish, let fire go out. When waiting to put away big bowl again, see dish of medium handkerchief only unexpectedly safe and sound.
同学们一听到这个实验名字就议论纷纷，我半信半疑地想：手帕怎么会烧不坏呢？正当我疑惑不解的时候，老师不慌不忙地拿出一块整洁的手帕。先用酒精把手帕完全浸湿，并拧干。接着，小心翼翼地用镊子将手帕夹到盘中，并用火柴点燃，同学们全神贯注地看着，生怕错过哪个精彩瞬间。没等大家满分/缓过神来，只听“呼”的一下，手帕燃烧起来了，火苗直往上窜，火越烧越旺，同学们一个个瞪着眼睛张大嘴。最后，老师见火烧得差不多了，就用大碗把盘子扣起来，让火熄灭。等再次把大碗拿开时，只见盘中的手帕居然安然无恙。
Look at classmates the appearance of each stare tongue-tied, the teacher tells us the burning point of alcohol is very actually low, lower than cloth and paper, when encountering fire, the alcohol of ignition point lowest begins to burn first, before alcohol evaporates completely, the handkerchief is to burn what do not wear, paper also is same principle.
看着同学们一个个瞠目结舌的样子，老师告诉我们其实酒精的燃点很低，比布和纸都低，当遇到火时，燃点最低的酒精先开始燃烧，在酒精完全蒸发完前，手帕是烧不着的，纸也是同样的原理。
Pass this today's test, I remembered a famous remark: Knowledge is treasury, but the key of open treasury is practice.
通过今天的这个实验，我想起了一句名言：知识是宝库，但开启宝库的钥匙是实践。(文/谢鑫悦)
