CET6丨IELTS丨TOEFL

外刊例句

The substance doesn't kill honeybees, and it works well on insecticide-resistant mosquitoes, too. So if it turns out to be safe enough to use around humans, the pesticide will give a whole new meaning to "bye-bye, sucker!”

这种化合物不会杀死蜜蜂,但是适用于抗药性的蚊子。如果结果证明在人类周围使用这些化合物是足够安全的,那这种农药就会有新的意义:“再见了,吸血鬼!”

——《科学美国人》

基本释义

pesticide:Pesticides are chemicals that farmers put on their crops to kill harmful insects.

n. 杀虫剂

追根溯源

单词pesticide里的词根cide来自拉丁语cidium,表示“杀”,所以,在英语里包含cide的单词,多与此相关。例如:

suicide /ˈsuːɪsaɪd/ v. 自杀

homicide /ˈhɒmɪsaɪd/ n. 杀人犯

genocide /ˈdʒenəsaɪd/ n. 种族灭绝

所以,pest(害虫) i(连接字母) cide=杀死害虫的东西→杀虫剂
