First, bird flu apparently leaves an odor imprint on bird feces, and so dogs-and even mice-could be trained to recognize it.

首先，显然，禽流感在禽类粪便上留下了气味，于是狗儿们，甚至小老鼠们训练后都可以辨别出来。

Even though the desk is wide, keyboards and mice take up room, so there can be a lot of jostling and adjustment on the desktop, and chairs and such can collide as well.

即使桌子较宽，有足够的空间给键盘和鼠标，同样会存在拥挤、调整桌面和椅子所带来碰撞等问题。
