2011.12英语六级阅读:气球放入微波炉
停!接下来的这个实验很危险。为了你和你周围的人的安全,请不要在家尝试。切忌不要尝试。
This is a balloon, but not just any balloon. It's filled with oxygen. No big deal,you might think, there is oxygen everywhere. True, but not pure oxygen.
现在这儿有一个气球,但是它不单单是一个气球。里面充满了氧气。你也许会想,没什么了不起的,到处都是氧气。没错,但是那不是纯氧。
Attached to the balloon is some tin foil, which will provide a spark.When the balloon is ignited,you don't see much of a flame. Due to the speed at which oxygen combusts, it burns so fast and clean

与气球相接的是一些锡箔,它们会产生火花。当气球被点燃时,你不会看见火焰。由于氧气燃烧的速度,燃烧的过程会如此的快和彻底以至于微波炉不会因火焰而受到一点损坏,而是被吹走
It is, however, nicely

我们做了这个实验因此你不必要
