樟脑丸----Mothball

大家好，欢迎来到小强英语。生活中，为了驱除飞蛾一类的小动物，有时候会用到樟脑丸。今天，我们来看樟脑丸用英语怎么说。Mothball. 这个词的构造挺有意思：moth是蛾的意思，而ball是球，合在一起就是樟脑丸。我们来看一下例句：

Mothballs are small balls made from chemicals that are placed in clothing to repel moths.
樟脑丸是用化学物质制成、放在衣物当中用来驱除飞蛾的小球。

Studies on mothballs have suggested that they may be carcinogenic, so people should be careful around them.
关于樟脑丸的研究表明他们可能致癌，所以大家要小心。

使用樟脑丸的时候需要注意两点：
No.1 For mothballs to work, they must be kept in a sealed container.
为了让樟脑丸起效，得把他们放在密闭的容器内。这一方面是让气体聚集，另一方面是保证人体的安全；

No.2 When someone wants to use something which has been mothballed in storage, it should be aired for a day or so before being worn or used, to allow the gas to dissipate. 简单地说，要使用经樟脑丸封存的物品，事先一天左右要拿出来通风，让气体消散后方可使用。
