Then, they found a cow grazing in a field.

突然，他们发现了一头正在牧场上吃草的奶牛。

Anyone who's seen cows grazing knows it's usually animals that eat plants, but some plants have turned the evolutionary tables to eat animals instead.

任何见过牛吃草的人都知道通常是动物吃植物，但一些植物已经改变了进化的方向，转而以动物为食。

If you look around me today, you see corn growing right up to the base of a wind turbine, another spot you'll see cows grazing right up to the base of a wind turbine.

而今如果你环顾四周，你会看到玉米一直长到风力机跟前，你将看到的另一个场景是奶牛吃草一直吃到风力机跟前。
