Kevin Hines, a manic-depressive, was 19 and in one of his weekly downswings on an overcast Monday morning in 2000. He went to the nearby Golden Gate Bridge to kill himself mostly because, with only a four-foot (1.2-metre) railing to leap, "I figured it was the easiest way." He dived over, but flipped and hit the water at 75mph with his feet first. His legs were crushed, but he somehow stayed conscious and started paddling with his upper body until the Coast Guard fished him out. Mr. Hines is one of 26 people who have survived suicide attempts at the bridge, but 1 223 are known to have succeeded (i. e., were seen jumping or found floating). People are throwing themselves off the bridge at the rate of two a month, which makes it the most popular place in the world for suicides. One book on the subject says that the Golden Gate is "to suicide what Niagara Falls is to honeymooners". Many San Franciscans think that the solution is to emulate the Empire State Building, the Sydney Harbour Bridge, the Eiffel Tower, St. Peter’s basilica and other such places and put up a simple barrier. This, however, is a decision for the 19 board members of the Golden Gate Bridge, Highway and Transportation District, an entity that oversees the bridge itself and the buses and ferries that operate in the area. Most of its revenues’ come from tolls and fares, and the district loses money. A barrier would cost between $15 million and $ 25 million. So the Psychiatric Foundation of Northern California, which has adopted the barrier as its cause, considers it a success that the board has merely allowed a feasibility study, for which various private and public donors have raised $ 2 million. Mel Blaustein, a director at the foundation, has heard several arguments against a barrier over the years-too ugly, too expensive, and so forth--but the most persistent has been that people would simply kill themselves somewhere else, so why bother.’ This is nonsense, he says, "Most suicides are impulsive and preventable." A bridge without a barrier, adds Pat Hines, Kevin’s father, is "like leaving a loaded gun in the psychiatric ward.\ What will the author mention after Paragraph 4

二、定义判断。每道题先给出定义,然后列出四种情况,要求你严格依据定义,从中选出一个最符合或最不符合该定义的答案。注意:假设这个定义是正确的,不容置疑的。 请开始答题: 不完全归纳推理就是根据一类事物中的部分对象具有(或不具有)某种属性从而推出该类事物的全部对象都具有(或不具有)某种属性的推理。 下列事例中,属于不完全归纳推理的是( )。 ①一个贩毒团伙共有六名成员,通过考察了解到这个团伙的每一个人都有前科,于是得出结论:这个贩毒团伙的所有人都有前科。 ②鲁班将“手被叶子为锯齿状的草划破”的事实用于“更快捷省力地伐木”的问题情景,从而创造出锯子。 ③人们发现元素的排列,天体的运动,四季的交替,生物的进化,社会的发展都是具有规律的,由此概括出:一切物体运动的形式都是有规律的。 ④一法医通过解剖几具溺水而亡的尸体,乙、丙溺水死亡内脏有硅藻反应,于是得出结论:凡是溺水者,其内脏都有硅藻反应。 ⑤麻雀会飞,燕子会飞,鸽子会飞,喜鹊会飞,老鹰会飞,海鸥会飞,因此所有鸟都会飞。
