[解析]
(1)推理判断题。根据第一段He had devoted his life to acting but had never been quite successful.(他把一生都献给了表演,但从未获得过成功。)可知,作者的老朋友想成为一名成功的演员的努力都失败了。D.He failed in all attempts to become a successful actor.(他想成为一名成功演员的所有努力都失败了。)符合文意,故选D。
(2)推理判断题。根据第四段Persistence pays off when it is rewarded with success,but it does not reward every person.For every JK Rowling,there are thousands of aspiring writers who will never get published.(坚持会得到成功的回报,但这并不会回报每一个人。对于每一个JK罗琳来说,都有成千上万的有抱负的作家永远无法出版自己的作品。)可知,作者提到JK罗琳主要是表明成功是不会发生在每个人身上的,故选B。
(3)词句猜测题。根据第四段Persistence pays off when it is rewarded with success,but it does not reward every person.(坚持会得到成功的回报,但这并不会回报每一个人。)以及For every Olympic athlete,there are innumerable(无数的)others who trained every day of their lives and never...( 对于每一位奥运会运动员来说,还有无数其他人每天都在训练,但从未…)可知,本段主要讲的是不是每个人都会成功,因此划线短语所在句子的意思是"虽然无数的奥林匹克运动员每天训练,但是却不成功",也就是不一定会达到标准,划线短语的意思是"符合要求的标准",故选B。
(4)推理判断题。根据倒数第二段Quitting when you're not ahead is sometimes the smartest thing to do.(当你没有领先的时候放弃有时候是最聪明的做法。)以及Sometimes,it is wise to put your energy into something else.(有时候,把你的精力放在其他事情上是明智的。)可知,如果我们失败了很多次,作者建议我们努力尝试新事物,故选A。
