比尔喜欢在闲逛时间观察鸟类。几年前,比尔买了一幢新房子,附近草木葱茏。入住后的第一个周末,他就在后院里装了个喂鸟器。就在当天日暮时分,一只松鼠弄倒了喂鸟器,吃掉里面的食物,把小鸟吓得四散而去。在接下来的两周里,比尔绞尽脑汁想出各种办法让松鼠远离喂鸟器,就差没有使用暴力了。但丝毫不起作用。 Bill likes to watch birds during strolling. A few years ago, Bill bought a new house with verdant vegetation nearby. On the first weekend after his arrival, he installed a bird feeder in the backyard. At the time of the day, a squirrel set up a bird feeder, ate the food, and scared the bird away. In the next two weeks, Bill racked his brains to come up with a variety of ways to keep the squirrel away from bird feeders, so he did not use violence. But nothing happens.
