　What does it mean to say that we live in a world of persuasion? It means that we live among competing interests. Your roommate’s need to study for an exam may take priority(优先)over pizza. Your instructor may have good reasons not to change your grade. And the object of your romantic interest may have other choices.

　In such a world, persuasion is the art of getting others to give fair and favorable consideration to our point of view. When we persuade, we want to influence how others believe and behave. We may not always prevail - other points of view may be more persuasive, depending on the listener, the situation, and the merits of the case. But when we practice the art of persuasion, we try to ensure that our position receives the attention it deserves.

　Some people, however, object to the very idea of persuasion. They may regard it as an unwelcome interruption into their lives. Just the opposite, we believe that persuasion is unavoidable - to live is to persuade. Persuasion may be ethical(合乎道义的)or unethical, selfless or selfish, inspiring or degrading. Persuaders may enlighten our minds or prey on our vulnerability. Ethical persuasion, however, calls on sound reasoning and is sensitive to the feelings and needs of listeners. Such persuasion can help us apply the wisdom of the past to the decisions we now must make. Therefore, the most basic part of education is learning to resist the one kind of persuasion and to encourage and practice the other.

　Beyond its personal importance to us, persuasion is necessary to society. The right to persuade and be persuaded is the bedrock of the American political system, guaranteed by the First Amendment to the Constitution(美国宪法)

　BROOKSVILLE - It’s the time of year again, when young bears are on their own for the first time. And that means more sightings where bears usually aren’t supposed to be.

　This weekend, a 258-pound black bear took a brief tour of Brooksville, with police and firefighters chasing.

　Another black bear, weighing just 100 pounds, was spotted Saturday, crossing busy U. S. 19 near a retirement community in Spring Hill. Several other bear reports have come from Citrus County.

　“It is really difficult for the younger bears to find their own land around here,” said Niki Everitt, bear hot line director for the Gulf Coast Conservancy.

　Brooksville’s bear first was spotted late Thursday crossing State Road 50, headed toward Tom Varn Park. Police and firefighters tracked the bear through the park and the Brooksville Quarry golf course.

　The bear then wound down the middle of Broad Street before being surrounded near Luigi’s Pizza. An official with the Florida Game and Fresh Water Fish Commission came with a tranquilizer spear (加入镇静的剂的矛), planning to stick the bear by hand.

　“The guy saw the size of the bear and figured that wasn’t a great idea,” said Capt. Frank Phillips of the Brooksville Fire Department.

　Emergency officials waited until a tranquilizer gun was brought from Land O’Lakes. The bear then got a free ride to the Chassahowitzka Wildlife Management Area.

　It is not unusual for bears to move into living areas this time of year, experts say. Mothers give their male baby bears the boot once the youngsters are 2 years old. With living areas growing, the young bears keep finding smaller and smaller areas in which they can set up their own land.

　“They’re trying to find a land of their own, where they won’t get beat up,” said Lt. Rip Stalvey, a game commission spokesman.

　Everitt said people should not be too concerned about the recent bear sightings, since “we have never had a bear attack in Florida.”

　Black bears mainly eat the tender and fresh leaves of Sabal palms, as well as acorns and berries. Recent weeks of dry weather likely have reduced their food supply.

　“If we don’t get some relief soon,” Everitt said, “we’re probably going to see a lot more of it.”
