阅读下文,回答相关问题

      ①有所不为,才能有所为。人生有很多可以放弃的东西,但万万不可轻言放弃的是:努力。
      ②你是否知道鲮鱼和鲦鱼的习性?鲮鱼喜欢吃鲦鱼,鲦鱼总是躲避鲮鱼,有人曾经用这两种鱼做了一个实验:实验者用玻璃板把一个水池隔成两半,把一条鲮鱼和一条鲦鱼分别放在玻璃隔板的两侧,开始时,鲮鱼要吃鲦鱼,飞快地向鲦鱼游去,可每次都撞在玻璃板上,游不过去。过了一会儿工夫,鲮鱼放弃了努力,不再向鲦鱼那边游去。更有趣的是,当实验者将玻璃板抽出来之后,鲮鱼也不再尝试去吃鲦鱼了!鲮鱼失去了吃掉鲦鱼的信心,放弃了已经可以达到目的的努力。
      ③其实,作为万物之灵的人,有时也会犯鲮鱼那样的错误。记得4分钟跑完1英里的故事吧?自古希腊以来,人们一直试图达到4分钟跑完1英里的目标。为了达到这个目标,人们曾让狮子追赶奔跑者,也曾喝过真正的老虎奶,但是都没实现目标。于是,许许多多的医生、教练员和运动员断言:人在4分钟内跑完一英里路程是绝对不可能的,因为,我们的骨骼结构不对头,肺活量不够大,风的阻力又太大。理由实在很多很多。
      ④然而,有一个人首先开创了4分钟跑完1英里的纪录,证明许许多多的医生、教练员和运动员的断言都错了。这个人就是罗杰•班尼斯特。更令人惊叹的是,一马当先竟引来了万马奔腾。在此之后的一年里,又有300名运动员在4分钟内跑完了1英里的路程。
      ⑤训练技术并没有重大突破,人类的骨骼结构也没有大的改变,数十年前被认为是根本不可能的事情,为什么今天变成了现实?是因为有人没有放弃努力,是因为有了榜样的力量。
      ⑥在由失败通往胜利的路上,有时候障碍的确存在,甚至很多;但有时候障碍已经消失,或已在不知不觉中被我们克服,可我们还误认为障碍仍然存在,不可逾越。可以说,有好多障碍并不是存在于外界,而是存在于我们的心里。
      ⑦几乎每个胜利者,都曾经是个失败者。胜利者与失败者的重要区别是:胜利者屡败屡战,决不轻易放弃努力;失败者偶遇挫折,却很快放弃了努力。
      ⑧在由失败通往胜利的征途上有道河,那道河叫放弃。
      ⑨在由失败通往胜利的征途上有座桥,那座桥叫努力。
