蟑螂是地球上最古老的昆虫之一，它们曾经与恐龙生活在同一时代。据化石证据显示，蟑螂早在4亿年前就出现在地球上了。但是，蟑螂非常不受地球人欢迎，它们臭名昭著，偷吃剩饭剩菜，有时还会咬破婴儿的皮肤。“蟑螂”和“蟑螂药”用英语怎么说呢?我们一起来学习。
首先，我们来看一段BBC官网的文章节选：
There was also a giant cockroach, but now we have a new super cockroach killer that we are going to test. Apparently one drop is enough and then as the cockroaches die the othercockroaches eat them and they die too. Luckily I will have left before we have a carpet of dead cockroaches in the house.

其实答案已经非常清楚了：
cockroach /ˈkɔkrəutʃ/ 蟑螂
cockroach killer 蟑螂药
