(2013·高考北京卷，B)Two dolphins race around in a big pool in the Ocean Park.The smaller dolphin，Grace，shows off a few of her tricks，turning around and waving hello to the crowd.The most amazing thing about her，however，is that she’s even swimming at all.She doesn’t have a tail.

Grace lost her tail as a baby when she got caught up in a fish trap.When the dolphin arrived at the Ocean Park in December 2005，she was fighting for her life.“Is she going to make it？”Her trainer，Abbey Stone，feared the worst.Grace did make it—but her tail didn’t.She ended up losing her flukes and the lower part of her peduncle.
Over the past six years，she has learned to swim without her tail.Dolphins swim by moving their flukes and peduncle up and down.Grace taught herself to move another way—like a fish! She pushed herself forward through the water by moving her peduncle from side to side.
The movements put harmful pressure on Grace’s backbone.So a company offered to create a man­made tail for her.The tail had to be strong enough to stay on Grace as she swam but soft enough that it wouldn’t hurt her.
The first time Grace wore the artificial tail，she soon shook it off and let it sink to the bottom of the pool.Now，she is still learning to use the tail.Some days she wears it for an hour at a time，others not at all.“The new tail isn’t necessary for her to feel comfortable，”says Stone，“but it helps to keep that range of motion (动作) and build muscles (肌肉)．”
Now，the dolphin is about to get an even happier ending.This month，Grace will star in Dolphin Tale，a film that focuses on her rescue and recovery.Her progress has inspired more than just a new movie.Many people travel from near and far to meet her.Seeing Grace swim with her man­made tail gives people so much courage.

(答案→)C 解析：　本文为一篇记叙文，属励志类文章。讲述了海洋公园的小海豚Grace尽管没有尾巴，却能克服困难，用另外一种方式游泳，并且还要拍电影《海豚的故事》以激励人们要勇敢地面对困难。【小题1】解析：选C。细节理解题。由文章第二段可知，当这只海豚在2005年12月刚到海洋公园时，“she was fighting for her life”，它的训练员说“Is she going to make it？”，由此我们知道，刚开始，它的训练员担心它能不能活下来。故正确答案为C项。【小题2】解析：选C。推理判断题。由文章第三段可知，小海豚Grace形成了它自己的游泳方式；由第五段内容可知，给海豚戴上人造尾巴不是为了让海豚舒服，而是为了让它保持一系列的动作，同时锻炼肌肉，也就是说，它带着人造尾巴的目的是调整游泳方式，故C项正确。【小题3】解析：选D。推理判断题。A项表示“坚持梦想”；B项表示“友好地对待动物”；C项表示“珍惜所拥有的”；D项表示“要勇敢地面对困难”。由文章内容可知，尽管小海豚Grace没有了尾巴，但是它克服了困难，以另外一种方式游泳，最后还提到，它要拍电影给人们带来鼓励，由此可知，这个故事是激励人们要勇敢地面对困难，故D项为正确答案。

这个解释是对的
