台湾籍旅美老师今天交给我们的句子是：
Mosquitoes have been around for a lot longer than people, millions of years, and have survived lots of predators and environmental changes. So that would be a lot of tough insects to kill, and a lot of bug deaths that wouldn’t affect humans at all.
蚊子存在于世界上已有数百万年，历史比人类还悠久，躲过了掠食者的侵袭、也度过了环境的变迁。所以要杀死所有的蚊子，就意谓着要杀掉一堆难缠的虫子，而且很多虫子即使死了对人类也不会有任何影响。
